Abstract

The "Musk v. Altman" lawsuit proceeding in the Oakland federal district court entered its most pivotal phase in its third week on May 12, 2026, exposing OpenAI CEO Sam Altman's personal investment portfolio to the courtroom. Documents submitted by Musk's lead attorney Stephen Moro revealed that Altman held personal stakes totaling over $2 billion (approximately ¥310 billion) across nine companies doing business with OpenAI, including Helion Energy, Stripe, Reddit, and Cerebras Systems. Silicon Valley VCs have shown a divided reaction to the governance crisis, while OpenAI, which is approaching its IPO, is facing a triple political headwind of a Congressional investigation, SEC review, and inquiry letters from state attorneys general.

Shocking Courtroom Revelation — On May 12, Altman's Portfolio Exceeding 240 Billion Yen Is Exposed

On May 12, 2026, the moment Sam Altman took the witness stand in the Ronald V. Dellums Federal Building courtroom in Oakland, California, the "dual structure" that Silicon Valley had vaguely sensed for more than a decade but never made visible was, for the first time, manifested as courtroom evidence. At the outset of cross-examination, Stephen Mollo, lead attorney for the Musk camp, presented an exhibit listing Mr. Altman's personal investments as of December 31, 2025. The document enumerated Mr. Altman's holdings in nine companies that had commercial or partnership relationships with OpenAI, with a combined market valuation comfortably exceeding $2 billion (approximately ¥310 billion). According to the breakdown reported as court filings by Reuters and U.S. News, the largest was Helion Energy at $1.7 billion (approximately ¥263.5 billion), followed by Stripe at $633 million (approximately ¥98.1 billion), proceeds from the sale of Reddit shares, longevity-medicine startup Retro Biosciences at $258 million (approximately ¥40 billion), Cerebras Systems, HR management software Lattice (formerly Degree), hardware startup Humane, AI software firm Software Applications, and AI pharmaceutical company Formation Bio (formerly Trialspark, $19 million / approximately ¥2.95 billion).

In a key article reported by CNBC on May 13, the scene in which Mr. Mollo pressed, "Are you a person who can be completely trusted?" was emblematic. Mr. Altman repeatedly stated that he had "appropriately distanced himself from conflicts of interest (recused) through formal board procedures," but did not directly address the structural question of why, at the very starting point of discussions, he had been recommending these companies as candidate business partners for OpenAI. The U.S. economic media outlet Sherwood News sharply mocked this configuration, writing "Sam Altman's favorite deal partner? Sam Altman.", and arguing that "Mr. Altman is seated on both sides of the deal, which is precisely the very structure Elon Musk has originally been criticized for." Mr. Altman's net worth is estimated at $4 billion (approximately ¥620 billion), and despite his public statements that he holds no direct equity stake in OpenAI itself, the fact that he had accumulated massive unrealized gains through equity in related business partners has rapidly surfaced as the core of the lawsuit.

The Musk v. Altman Lawsuit — Elon's Fury Over "Having a Charity Stolen"

At its core, this lawsuit concerns how OpenAI—which started as a charitable organization—transformed into a for-profit enterprise in contradiction to its founding spirit, and how, throughout that transformation, co-founder Elon Musk, who in the early days pledged $1 billion in support and actually contributed $44 million (approximately ¥6.8 billion), was completely shut out of governance. In court, Musk repeatedly invoked the line "You can't just steal a charity" as if it were a magic incantation. According to testimony reported by multiple outlets including Al Jazeera, CNBC, and MIT Technology Review, Musk fumed that "the $38 million I provided (approximately ¥5.89 billion, his final actual contribution) was effectively gratuitous funding, and it gave rise to what is now an enterprise valued at $800 billion (approximately ¥124 trillion)."

The suit was originally filed on February 29, 2024, in the California state court in San Francisco, and then refiled on August 5 of the same year in the U.S. District Court for the Northern District of California (N.D. Cal.). Musk initially asserted 26 claims, but by the time the trial began in April 2026, only two remained: "unjust enrichment" and "breach of charitable trust." The remedies Musk seeks boil down to three points. First, a complete return of OpenAI to a nonprofit structure; second, the removal of Mr. Altman and President Greg Brockman from their roles as directors and executives; and third, the redirection of the $134–150 billion (approximately ¥20.8–23.3 trillion) sought in damages to the OpenAI nonprofit foundation. Al Jazeera analyzed that "Musk has structured his suit such that he personally receives no monetary gain whatsoever, which lends his arguments strong legal and moral persuasive force."

The case is being handled by U.S. District Judge Yvonne Gonzalez Rogers. Judge Rogers has divided the case into two stages—a "liability phase" and a "remedies phase"—and indicated that the liability phase is expected to conclude by May 21, 2026. Nine jurors have been empaneled, but their verdict is "advisory," with the final ruling to be issued solely by Judge Rogers.

Background of the Lawsuit and Progression of the Trial — From the 2024 Filing to Testimony in May 2026

Tracing the chronological maturation of this lawsuit, the structure clearly emerges in which the governance crisis traces back to the root of "Altman as an individual investor."

On February 29, 2024, Musk filed his initial complaint in a California state court, claiming that OpenAI had abandoned its original nonprofit mission of pursuing "the benefit of humanity as a whole." On August 5 of the same year, the lawsuit was refiled in federal district court, and in November, Musk filed a preliminary injunction motion seeking to "enjoin OpenAI from completing its full conversion to a for-profit enterprise." His argument relied on the logic that the total $44 million (approximately ¥6.8 billion) he had contributed between 2016 and 2020 was made under the promise of a "nonprofit mission."

On January 7, 2025, a hearing on the preliminary injunction was held in the court of Judge Gonzalez Rogers in Oakland. In February of that year, the judge denied the preliminary injunction, assessing Musk's claim of "irreparable harm" as "a stretch." Also in February, a "corporate-level tectonic shift" that astonished media worldwide occurred when Musk proposed to acquire control of OpenAI itself for $97.4 billion (approximately ¥15.1 trillion), and Altman immediately rejected it. In April, 12 former OpenAI employees submitted an amicus brief to the court arguing that OpenAI had abandoned its nonprofit origins. That same month, OpenAI countersued Musk, arguing that "Musk's series of actions are a deliberate tactic to obstruct a competitor for the benefit of his own company (xAI)."

In November 2025, evidence files submitted by Musk's legal team to the federal district court brought to light an internal message in which, on February 9, 2023, Altman consulted Shivon Zilis (mother of one of Musk's children and an OpenAI board member at the time) about whether to "publicly praise Musk on X."

Then, on April 27, 2026, the selection of nine jurors was completed, and the full-fledged trial began. The first week (April 28-30) featured three consecutive days of testimony from Musk himself. MIT Technology Review summarized the first week as "Musk said he was duped, warned that AI might kill us all, and admitted his own company xAI is distilling from OpenAI models." The second week (May 4-8) centered on testimony from OpenAI President Greg Brockman and Shivon Zilis, with Zilis delivering stunning testimony that "Musk recruited Altman to the Tesla board" and "Musk demanded a 90% stake in OpenAI."

In the third week, on May 11, Microsoft CEO Satya Nadella testified, and on May 12, after OpenAI board chairman Bret Taylor continued his testimony, Altman finally took the stand. And that same day, the decisive moment referenced at the opening of this article arrived: Musk's attorneys presented Altman's personal investment portfolio to the court. Closing arguments are scheduled for Thursday, May 14, and the advisory jury verdict on the liability determination phase and the judge's ruling are expected to be handed down within next week.

Helion Energy — Unrealized gains equivalent to 263.5 billion yen in nuclear fusion startup

The relationship that has received the most coverage as a symbol of Mr. Altman's conflicts of interest is his connection to the nuclear fusion startup Helion Energy. Based in Redmond, Washington, Helion Energy is a company developing nuclear fusion (D-He3 reaction) technology, aiming to deliver electricity at commercial scale by 2028. According to a series of reports by GeekWire and TechCrunch, Mr. Altman has served as Chairman of Helion's board since 2015, and in the 2021 $500 million funding round he personally invested $375 million (approximately ¥58.1 billion) as a central backer, making him one of the top-tier shareholders holding roughly one-third of all Helion shares. The market value of his personal stake reached approximately $1.7 billion (approximately ¥263.5 billion) as of the end of 2025, making it by far the largest position in Mr. Altman's personal portfolio.

The problem lies in dealings with OpenAI. In May 2024, Helion Energy entered into a basic agreement to supply electricity to OpenAI, and reports by TechCrunch and Axios in March 2026 stated that "negotiations are underway toward a larger contract, with the possibility that OpenAI could secure up to 12.5% of Helion's production capacity (equivalent to 5 GW by 2030 and 50 GW by 2035)." Around this same time, Mr. Altman resigned from his position as Chairman of Helion's board in March 2026. This was explained as a "preemptive resolution of conflicts of interest" ahead of negotiations on a large-scale contract that could potentially include OpenAI's investment of around $500 million.

However, critics have dismissed this timing as "far too late." Sherwood News pointed out that "OpenAI's board has offered no convincing explanation as to why it deemed it appropriate to consider investment in and power purchases from a fusion startup chaired by Altman, at a stage when commercialization prospects have yet to be established." A formal letter of inquiry sent to Mr. Altman on May 8, 2026, by Representative James Comer, Chairman of the U.S. House Oversight Committee, specifically named the Helion deal. As detailed by GeekWire, Chairman Comer expressed strong concern regarding this transaction about "the possibility that the financial resources of a nonprofit foundation may have been used in ways that ultimately boosted the valuation of Mr. Altman's personal holdings," and demanded detailed documentation regarding what conflict-of-interest management protocols OpenAI was operating internally.

In court, Mr. Altman acknowledged that "a considerable portion of my time at OpenAI is devoted to securing energy and computing resources," while defending himself by stating, "I have consistently removed myself from Helion-related decision-making and final terms approval." However, whether "recusal" was substantively functioning under a structure in which the CEO is the most important decision-maker at both companies remains at the core of the controversy.

Reddit — Holdings of Over 60 Billion Yen Pressed as "The Most Obvious Conflict of Interest"

Altman's conflict of interest surrounding Reddit can be called the most sensationally handled individual matter in the lawsuit, both in terms of its scale and its nature. According to SEC filings and Fortune magazine reports, Altman has been a long-standing investor who has continuously supported Reddit since his Y Combinator days, and as of the day of Reddit's IPO in March 2024, he held approximately 8.7% of the shares, making him the third-largest shareholder behind the Newhouse family (Advance Publications) and Tencent. On the day of the IPO, Altman's holdings were valued at over $600 million (approximately ¥93 billion), and within his personal portfolio, Reddit was positioned as one of his most successful investments in a "media company."

The issue is the comprehensive data licensing agreement concluded between that very Reddit and OpenAI. This partnership agreement, announced on May 16, 2024, granted OpenAI the right to use Reddit's structured posting data for training and inference of ChatGPT, while Reddit received direct compensation from OpenAI and additionally expected increased traffic to Reddit content through ChatGPT. As of May 2024, Fortune had already written that "Altman is the leader of OpenAI and simultaneously one of Reddit's largest shareholders, standing at the intersection of both companies' interests," seeing through to the heart of the conflict of interest. Moro, the lead attorney for the Musk camp, took up precisely this May 2024 contract negotiation in cross-examination on May 12, asserting that "the discussions led by Altman involved an 'obvious conflict' of interest."

In court, Altman explained that "the final terms were approved by the board of directors," "there were multiple others present besides me," and "this was a standard corporate recusal procedure." OpenAI has officially announced that "the contract was led by OpenAI's COO and approved by the independent board of directors" and that "Altman recused himself from the decision." However, what is noteworthy is the fact, shown in court documents, that "Altman had divested his Reddit holdings by the end of 2025." According to what Slashdot reported as statements by Reddit co-founder Alexis Ohanian, Ohanian said that back in 2015-2016, when Altman proposed "letting him aggressively scrape all of Reddit's data," he "felt in his gut that he should pass," and that he opposed it internally, saying "Altman is very smart, but incredibly cunning, and I don't think he's the world's most charitable person." It is an ironic configuration in which the co-founder's instinctive rejection ultimately exploded in court a decade later as "the central stage of a conflict of interest."

Stripe — ¥98.1 Billion in Held Shares and the Cozy Ties with OpenAI's Payment Infrastructure

Altman's stake in payments infrastructure giant Stripe simultaneously embodies the "oldest entanglement" and the "deepest structural collusion" among the conflict-of-interest allegations. Stripe, a fintech behemoth co-founded in 2010, remains known today as a privately held mega-unicorn (with a market valuation of approximately $159 billion, or about ¥24.6 trillion). A widely circulated anecdote in tech circles holds that Altman invested $15,000 (about ¥2.3 million) in Stripe's early days to acquire roughly 2% of the company, and the current market value of his holdings has swelled to $633 million (about ¥98.1 billion).

This pre-existing investment relationship has come to carry a fraught commercial dimension as OpenAI has adopted Stripe as the core foundation for ChatGPT subscription billing, API billing, and payment settlement for Enterprise contracts. Sherwood News argues, "Stripe is the most important partner standing on the side of commercializing OpenAI's technology, and the two companies are tied together across multiple dimensions including payments infrastructure, sales channels, and joint development initiatives. Altman holds the rare dual privilege of having access to the highest-level decision-making at both companies." Interactions between Stripe co-founder John Collison and Altman have been publicized repeatedly at official events such as "Stripe Sessions," but from critics' perspective, this should be understood not as a mere friendship but as a "market alignment" built atop a long-term, mutually dependent business relationship.

In court on May 12, attorney Molo argued regarding the Stripe matter that "Altman sat at the center of a series of decisions that led OpenAI to adopt, as a business partner, a counterparty from which he personally profits as an investor," asserting that it bears the same structural problems as the Helion, Reddit, and Cerebras cases. OpenAI has countered that "the deal with Stripe is an operational payment-vendor selection, a judgment independent of Altman's personal holdings." However, given that independent alternative payment providers (such as Adyen, Worldpay, and PayPal) offer equivalent functionality, no clear evidence has yet been presented in this lawsuit as to why Stripe continues to be chosen—or whether the OpenAI board went through an explicit comparative selection process.

Cerebras Systems — Warrants and Individual Holdings Swell Amid IPO in the Midst of Litigation

The strangest and most symbolic aspect of the lawsuit was the coincidence in timing: during the very same week the trial was proceeding, Cerebras Systems—a company in which Mr. Altman is a personal shareholder and with which OpenAI has signed a massive compute contract—was listed on NASDAQ. Cerebras Systems is a San Jose-based AI semiconductor startup, known for its innovative design called the Wafer-Scale Engine (WSE), which uses an entire silicon wafer as a single chip. The company's chips are claimed to deliver throughput in inference workloads far exceeding GPU-based systems, and they have attracted attention as one of the few practically deployed contenders challenging NVIDIA's stronghold.

The major contract with OpenAI was reported by TechCrunch on January 14, 2026. Under the multi-year contract, OpenAI is to secure 750 megawatts' worth of compute capacity from Cerebras from 2026 through 2028 for over $10 billion (approximately ¥1.55 trillion), with SiliconANGLE and other outlets later reporting that "in substance, it could reach a scale of $20 billion (approximately ¥3.1 trillion)." More importantly, in conjunction with this compute contract, Cerebras agreed to "issue warrants (rights to purchase shares) equivalent to up to 10% to OpenAI." This corresponds to approximately $5 billion (approximately ¥775 billion) at the midpoint price of Cerebras' IPO. In addition, in December 2025, OpenAI extended a $1 billion (approximately ¥155 billion) loan to Cerebras, which was collateralized by warrants enabling the purchase of over 33 million shares.

Then, on May 13, 2026, Cerebras was listed on NASDAQ under the ticker "CBRS." According to CNBC reports, the initial provisional range—first set at $105–$115/$115–$125—was raised to $150–$160 in response to bullish demand, and shares were ultimately offered at $185 (approximately ¥28,700), a price above the top of the range. By selling 30 million shares, the company raised $5.55 billion (approximately ¥860.2 billion), and its equity market capitalization surpassed $56 billion (approximately ¥8.68 trillion). It became the largest tech IPO of 2026.

Mr. Altman himself held approximately 89,000 Cerebras shares as of the end of December 2025, valued at approximately $16.5 million (approximately ¥2.56 billion) based on the IPO price. Documents presented in court had stated $3.2 million (approximately ¥496 million) as of the end of 2025, but following the surge in the IPO price, the figure jumped roughly fivefold. OpenAI co-founder Greg Brockman and former chief research scientist Ilya Sutskever are also listed among Cerebras' early investors. The critics' point is clear: namely, the $10–$20 billion compute contract by OpenAI pushes up the corporate value and IPO valuation of its counterparty Cerebras, and as a result, structurally produces gains for Mr. Altman and his associates in their personal positions. BanklessTimes wrote, "It was the OpenAI contract that staged the climax of Cerebras' listing. Nearly half of the company's revenue depends on a single counterparty—namely, OpenAI," raising questions about the very commercial soundness of the business itself.

TBPN Acquisition and Reddit Investment — The Dirty Strategy of "Buying Media to Control the Narrative"

To begin with, Altman and OpenAI's strategy of acquiring narrative-shaping power through investments and acquisitions of "media companies" is not limited to a personal investment in Reddit. On April 2, 2026, OpenAI announced its first media company acquisition: the purchase of the popular technology industry talk show "TBPN (Technology Business Programming Network)." According to the Financial Times, the total transaction value was in the "low hundreds of millions" of dollars—that is, roughly $100–500 million (approximately ¥15.5–77.5 billion). TBPN is a daily live-streaming program that only launched in 2025, co-hosted by John Coogan and Jordi Hays. Although mid-sized in terms of audience—with about 58,000 YouTube subscribers and approximately 70,000 daily viewers—it is a "subculture-type" media outlet with extraordinarily outsized influence over Silicon Valley's tech elite, VCs, and founder class. Its advertising revenue in 2025 was approximately $5 million (about ¥775 million), and it was projected to exceed $30 million (about ¥4.65 billion) in 2026.

The problem is the fact that this program has been incorporated into OpenAI's strategic division and placed under the direct jurisdiction of Chris Lehane, OpenAI's chief political operative. Lehane was a crisis management specialist known as the "Master of Disaster" during the Clinton administration, and is renowned as a formidable political and regulatory affairs expert who served as SVP at Airbnb.

Slate.com discussed this acquisition in a scathing article titled "Why Sam Altman's purchase of TBPN is so sleazy." The article's core critique was as follows: at a time when tech media is already deteriorating from "adversarial investigative journalism" into "access-driven friendly coverage," massive capital like OpenAI directly owning such programs will completely transform the tech media environment into a "venue for celebration and promotion," depriving it of the opportunity for critical scrutiny that is genuinely needed. Slate wrote, "If the path to a big hit is making a podcast that Altman will love, the rest of us are in trouble."

CNN Business cut to the chase even more bluntly, framing the structure as: "OpenAI isn't just buying a podcast — it's buying influence." Alex Kantrowitz, a former BuzzFeed reporter who now runs Big Technology, wrote, "The TBPN acquisition is a failure. The moment it comes under OpenAI's umbrella, everything TBPN says will be regarded as 'OpenAI marketing' and will lose its credibility." Tech critic Sara M. Watson similarly argued to NPR, "This is a sign that AI and tech are facing a larger 'narrative shift problem.' Public opinion has already moved into a mode of 'we are skeptical of your claims.'" Implicator.ai published an article with the biting title, "OpenAI bought TBPN. Stop calling it 'editorial independence.'" Inc. magazine summarized it as, "This is the latest form of the strategy Silicon Valley is perfecting—namely, 'cut out traditional tech-skeptical news outlets and build media you own.'"

Returning here to the Reddit investment story, the structural parallel is obvious. As a personal investor, Altman holds the position of Reddit's third-largest shareholder, and that same Reddit, as the largest supplier of AI training data, received compensation from OpenAI reportedly on the order of $200 million (about ¥31 billion)—which simultaneously pushed up Reddit's stock price and Altman's personal unrealized gains. Reddit's IPO (March 2024) took place alongside parallel partnership negotiations with OpenAI, and many market observers have pointed out that "just before the OpenAI deal was publicly announced, Reddit caught a tailwind for its listing." In an article published on Medium, "Reddit's deal with OpenAI might break everything," Dominic Carlon details how the anger among Reddit communities, moderators, and general users centers on the point that "the data they spent more than a decade building was sold off behind their backs, without them receiving any compensation in return, as AI training data in a manner directly tied to the profits of major shareholder Altman."

When these two moves—Reddit and TBPN—are placed side by side, a single strategy emerges. Whether as a personal investor or in his capacity as OpenAI's CEO, Altman is systematically seizing the venues that shape narratives (platforms), data supply sources, and interpretive apparatuses (podcasts). Many media critics have pointed out that, even within the current of so-called "tech-built media" in Silicon Valley, this represents an unusual scale and degree of control.

Silicon Valley VC Reactions — A Divided Response to the Governance Crisis

The reaction within Silicon Valley's VC community is by no means monolithic. Vinod Khosla (Khosla Ventures), known as OpenAI's largest backer, remarked on the underlying structure of the lawsuit during the early-March 2026 podcast "Titans and Disruptors of Industry": "Musk wanted to be CEO. He wanted to run OpenAI as his own 'private fiefdom.' When that didn't happen, he held Sam, Greg and the others hostage, and Sam had no choice but to look for another source of funding." Fortune magazine characterized this as "the moment OpenAI's most important VC backer clearly aligned himself with the Altman camp."

Yet within that same Silicon Valley, other VC figures have voiced serious concerns. Bret Taylor, chair of OpenAI's for-profit corporate board, defended Altman in his May 12 testimony, stating, "Sam has been highly transparent and has openly shared information about outside investments." However, under cross-examination, when pressed by Musk's attorneys with the question, "In November 2023, didn't you yourself initially decline the board seat because you had concluded Sam was a liar?" Taylor acknowledged, "That is correct," before adding, "However, at the time, I was not in possession of all the facts." This was reported as a vivid scene illustrating that the defensive line of the VC and board side in court is more fragile than expected.

The core argument advanced by the board side during the November 2023 ouster drama of Altman — namely that "Altman had not disclosed sufficient information about his startup holdings to the board, making it impossible to understand how he might personally benefit from transactions" — has been re-cited by multiple outlets including Sherwood News. At the time, Reid Hoffman (Greylock), one of the central VC figures who actually criticized the move to oust Altman, took the stance of denouncing the ouster as "a failure of board governance," but as of May 2026 has been avoiding official comment. How the VCs who moved to defend Altman at the time will confront the current scandal has become a focal point of industry attention.

TechCrunch's May 13, 2026 article "Who trusts Sam Altman?" succinctly summarizes Silicon Valley VC's divided psychology. The article wrote: "Investors who continue to back Altman cite OpenAI's scale, speed, and dominant position. On the other hand, investors who have begun to distance themselves are questioning the very credibility of its governance itself." Andreessen Horowitz, SoftBank, Sequoia Capital, and Thrive Capital currently maintain an officially continuing stance of supporting OpenAI, but CFO Sarah Friar's statement that "OpenAI will not be ready for a public listing in 2026" was revealed in April 2026 Fortune reporting, and the realistic possibility that the IPO will be pushed back to mid-to-late 2027 is gaining traction.

In parallel, a line of argument has emerged from within Silicon Valley itself: "Altman's investment structure forces a reconsideration of the entire governance of major tech companies, including OpenAI's principal investors Microsoft and Tesla (Musk's shareholding ratio)." Analyses from NAI 500 and TradingKey pointed out that "Altman's recusal defense raises a question to the entire industry as to whether the traditional safeguards of corporate governance are sufficient to handle the issue of a CEO's personal portfolio." The view is that the practice widely conducted in Silicon Valley of "parallel investment by CEOs into related companies" may, in the wake of the OpenAI lawsuit, change the very nature of board accountability.

Some coldly observant figures in the VC industry view this not as "Altman's personal crisis," but rather analyze it as "the result of Silicon Valley as a whole having structurally neglected CEO conflicts of interest, with the bill coming due all at once as the AI market expands in scale." The growing cynical reception within the industry is that Altman's side portfolio, exceeding $2 billion (approximately ¥310 billion), has made visible the ultimate expression of Silicon Valley-style "concentration of power and capital."

Future Developments — Next Week's Verdict, Congressional and SEC Investigations, and the Blow to IPO Plans

In the short term, the most noteworthy events are the closing arguments on May 14, 2026, followed by the advisory jury verdict in the liability determination phase next week (the week of May 19-22), and the final ruling by presiding Judge Rogers. If the Musk camp prevails, the case will move into a second phase where dramatic remedies will be debated—a structural rollback of OpenAI's for-profit structure, or at the very least the removal of Mr. Altman and Mr. Brockman. If the Altman camp prevails, the IPO plan and the long-term partnership with Microsoft will be secure, but issues concerning his personal portfolio will nonetheless continue along the separate schedules of congressional investigations and SEC review.

In the medium term, the focus will be on the deadline for responding to the House Oversight Committee's (Chair: Rep. James Comer) letter of inquiry dated May 8, and the subsequent holding of hearings. Chairman Comer's questions specifically name Helion Energy and demand the production of all documents related to conflict-of-interest management systems at OpenAI. Republican state attorneys general from Alabama, Arkansas, Florida, Idaho, Iowa, Louisiana, Montana, Nebraska, Oklahoma, and West Virginia (10 states in total) have sent a letter to SEC Chairman Paul Atkins requesting a pre-IPO review of OpenAI. This is both an individual regulatory risk and a political headwind that will have the effect of prolonging the IPO process.

In the long term, the impact on the IPO is serious. As Fortune reported in April 2026, OpenAI CFO Ms. Friar has already revealed an internal divergence of views with Mr. Altman, stating that "there will be no listing during 2026." The listing valuation that OpenAI is targeting—on the scale of $852 billion (approximately ¥132 trillion) to over $1 trillion (approximately ¥155 trillion)—is for institutional investors an issue inseparable from "confidence in Sam's suitability as CEO," and the possibility that the litigation verdict, congressional investigation findings, and SEC determinations will trigger a cascading delay of the listing timing has taken on real plausibility. Multiple analytical sources view "a listing in mid-2027 or later" as the most realistic scenario.

Finally, to organize the key points from a Silicon Valley VC perspective, the following structure emerges. First, the fact that the CEO of the leading company in the AI market holds over $2 billion (approximately ¥310 billion) in personal positions in his partner and counterparty firms combined has been a semi-open secret within the ecosystem for some time, but with its emergence as evidence in court, a structure has formed in which pressure is mounting simultaneously from four directions: institutional investors, regulators, Congress, and state attorneys general. Second, the strategy of dominating media, data, and narrative—through personal investment in Reddit and the corporate acquisition of TBPN—will be recorded as the most integrated example of Silicon Valley's "tech-bro media" movement. Third, the timing of Cerebras's IPO has unfortunately provided regulators, the SEC, and critics with a perfect case study as a textbook example of the circular structure: "OpenAI awards a contract → the contractor's valuation rises → Altman's personal unrealized gains expand."

The moment Silicon Valley's "concentration of power and capital" crosses a certain critical threshold, this series of events will be recorded as the marker. Next week's verdict, the subsequent moves by Congress and the SEC, and the restructuring process of OpenAI's IPO strategy will long be retold as the case that defined new standards for AI industry governance.
