Sutskever Testifies on His $7 Billion Stake and the Events Behind Altman's Removal from OpenAI

Ilya Sutskever, the former chief scientist and co-founder of OpenAI, testified Monday in the Musk v. OpenAI lawsuit, disclosing his ownership stake of approximately $7 billion in the company's for-profit arm. He also provided the most detailed public account yet of what happened when the board voted to remove CEO Sam Altman in November 2023 — a move that lasted only a few days before Altman was reinstated.

In his hour of testimony, Sutskever explained his role in gathering evidence against Altman over the course of a year, claiming the CEO had engaged in a pattern of deception. He also revealed that he had turned down a $6 million annual job offer from Google to join OpenAI, highlighting the financial incentives that drew the company's founders. OpenAI is now valued at $850 billion.

The November 2023 Board Action

Sutskever's testimony focused on his involvement in the board's decision to oust Altman, a moment that sparked a company-wide backlash and Altman's return to the CEO role within days. Court records show that Sutskever spent roughly a year gathering material he believed demonstrated that Altman was being dishonest, working with other board members to build a case for removing him.

During the attempted ouster, Sutskever helped draft a memo — now referred to as the "Brockman memo" in legal filings — that became central evidence in Musk's lawsuit. A court order required Sutskever to turn this memo over to the plaintiffs, though its full contents have not been released publicly.

Sutskever testified that he has not spoken with Altman or co-founder Greg Brockman since the failed coup. The break widened when Sutskever departed OpenAI in 2024 and launched his own competing AI research company. He also revealed that he stayed offline over the weekend following Altman's firing, suggesting the intense public backlash took the board members by surprise.

The Money and What It Means

The courtroom testimony put numbers on the stakes at play. Sutskever's $7 billion stake is a large piece of OpenAI's $850 billion valuation. Co-founder Greg Brockman holds roughly $30 billion in shares. These figures matter because Musk's core legal argument is that OpenAI abandoned its original mission — operating as a nonprofit focused on AI safety — and instead prioritized profit.

Think of it this way: when you create something with a nonprofit mission but later shift to a for-profit model, the financial rewards to the people running it can get very large. Musk's lawyers contend that these big financial incentives may have changed OpenAI's priorities, moving the company away from its stated goal of developing AI for humanity's benefit and toward growth and shareholder returns.

Sutskever's choice to leave a lucrative offer from Google in favor of joining OpenAI also shows how the founders calculated early on: equity in a high-potential company could be worth more than a large salary.

Safety Research and What Happened to It

Sutskever had overseen OpenAI's superalignment team, which was focused on making sure future AI models would be safe and aligned with human values. The company disbanded this team in May 2024, shortly after Sutskever left.

That move — shutting down the safety research program that Sutskever had led — has become important in Musk's lawsuit. It suggests that OpenAI may have shifted its priorities away from safety research, the research approach that helped define the company's original mission.

Who Said What in Court

Musk's legal team tried to treat Sutskever as a hostile witness, which is telling. Even though Sutskever had played a role in removing Altman, Musk's lawyers seemed to believe his testimony would not help their case. This suggests the motivations and loyalties among OpenAI's former leaders are complicated and don't neatly fit the lawsuit's narrative.

The trial, overseen by US District Judge Yvonne Gonzalez Rogers, has also heard from other executives, including Microsoft CEO Satya Nadella and OpenAI's board chair Bret Taylor. Former OpenAI executives Greg Brockman, Mira Murati, and Shivon Zilis have testified as well, building a detailed record of how the company made its major decisions.

What This Case Is Really About

At its core, this lawsuit raises a question that extends beyond OpenAI: when a nonprofit organization becomes a for-profit company, how do you ensure it stays true to its original mission. We have seen this tension before in the history of technology — think of early internet companies founded with idealistic goals that later shifted to profit-focused models. The difference here is the stakes. Decisions about how to develop advanced AI systems carry implications that go well beyond a typical business dispute, affecting society more broadly.

Sutskever's departure and his decision to launch a competing AI lab shows that this is not just a legal battle. It reflects a real disagreement among OpenAI's founders about the right path for AI research and whether safety should come first or second.

The financial stakes revealed in Sutskever's testimony are striking. Billions of dollars in personal wealth hang on decisions about what OpenAI prioritizes. When the financial incentives for company leaders become this large, those incentives inevitably shape which projects get funded, which get cut, and which safety measures get prioritized. The fact that OpenAI disbanded its superalignment team shortly after Sutskever left suggests that safety research, however well-intentioned, became harder to sustain under the commercial pressures the company faces.

This case will likely set precedent for how the law views nonprofit-to-for-profit transitions in the technology industry. As OpenAI's story unfolds in court, it is also shaping questions about AI governance and what structures we might need to ensure that advanced AI development serves broader human interests, not just shareholder returns.
