Week three of the Musk v. Altman trial opened Monday with something nobody in that Oakland courtroom had experienced in three weeks of testimony: a tech CEO who answered questions. Completely. Without philosophical objections to the nature of yes or no.

Satya Nadella walked in wearing a navy suit and a blue tie. He had been seen pacing the hallway before taking the stand. He answered every question. He finished his testimony and left. No threats sent over the weekend. No prediction market on his posting volume. No request from the judge to please consider the concept of social media restraint.

The jury appeared briefly confused by the experience.

One irony worth naming upfront: Musk's lawyers called Nadella as their witness. He ended up throwing cold water on their case.

The IBM email is the most interesting document of the day. In an internal memo written as Microsoft was preparing to invest another $10 billion in OpenAI, Nadella wrote that he didn't want Microsoft to "be IBM and OpenAI to be Microsoft." The reference is to IBM's 1980 deal with a young Microsoft over DOS — the arrangement that let Microsoft sell the operating system to every other PC maker and eventually become the more powerful company.

Musk's attorney walked him through it in court. Then noted that Microsoft's market cap is now $3 trillion. IBM's is $210 billion.

Nadella confirmed both numbers. His strategic anxiety about being outmaneuvered was right there in his own writing. The investment was never charitable. It was a calculated bet against becoming the smaller company in a defining partnership. He said as much on the stand: Microsoft's funding was commercially motivated from the beginning.

Which is actually useful for OpenAI's case. You can't breach a charitable trust using money that was never donated as charity.

The knife Microsoft's own lawyers then deployed: they walked Nadella through three major moments in the partnership — the 2019 investment, the 2020 GPT-3 license, the 2023 $10 billion round — and asked each time whether Musk had contacted Nadella to raise concerns. Each time: no. They have each other's phone numbers. The man suing over the betrayal of the partnership never called the partner to complain about it.

And then the detail that should interest the California AG more than anyone: under cross-examination, Nadella acknowledged he was not aware of any full-time employees at the OpenAI nonprofit before March 2026. No grants. No research. No open-sourced technology the nonprofit had produced.

Microsoft invested $13 billion in a partnership with an entity whose nonprofit shell had, apparently, nothing inside it. Nobody asked. Nobody checked. The Microsoft CEO found out in federal court.

He described the November 2023 crisis — when Altman was briefly fired and nearly everything fell apart — as "amateur city."

Three weeks in, that might be the most accurate two words spoken in that building.

After Nadella wrapped, Ilya Sutskever took the stand.

The man who planned Altman's removal for at least a year. Who sent a 52-page memo as disappearing emails that lawyers kept copies of. Who described the board that acted on it as "rushed and inexperienced" — meaning himself.

He testified Monday that he spent about a year gathering evidence that Altman had displayed a "consistent pattern of lying." Altman's conduct included "undermining and pitting executives against one another." He had discussed removing Altman with Mira Murati — the same CTO who said "No" under oath last week — for a long time.

His entire defense of OpenAI's mission pivot landed in seven words:

"The mission of OpenAI is larger than the structure."

That's it. That's OpenAI's entire defense. The nonprofit structure was never the point. The technology and what it does in the world is the point. Musk is suing over the wrapper. Sutskever just told the jury the wrapper was always beside the point.

He also testified there were never any promises made that OpenAI would remain a nonprofit. Which, if the jury believes it, ends the breach of charitable trust argument entirely.

Board chairman Bret Taylor rounded out Monday, telling the jury repeatedly that the company remained dedicated to saving humanity. The jury has now heard that phrase enough times that it is either very comforting or has completely lost meaning.

Meanwhile, outside the courtroom, Monday kept going.

Cerebras bumped its IPO price range Monday — the chip company at the center of the undisclosed self-dealing testimony, where both Brockman and Altman held personal stakes while OpenAI signed a $20 billion-plus compute commitment — from $115-$125 per share to $150-$160, pushing the fully diluted valuation toward $48.8 billion. The offering is reportedly more than 20 times oversubscribed. It prices Wednesday. The same week the trial wraps.

Sutskever just confirmed on the stand that his OpenAI stake is worth $7 billion. Brockman's is $30 billion. Both held undisclosed Cerebras positions while that deal was being structured. The Cerebras IPO prices Wednesday. The trial closes Wednesday.

The timing is not subtle.

And OpenAI announced the Deployment Company — a new $4 billion vehicle backed by 19 private equity firms including TPG, Brookfield, Bain Capital, and SoftBank, designed to push OpenAI's technology into corporate clients. SoftBank — the same SoftBank holding a $40 billion unsecured bridge loan with one repayment path — is now also a founding partner of the enterprise deployment vehicle. They are very committed to this IPO working out. The PE firms aren't just capital providers. Their portfolio companies now have aligned financial incentives to adopt OpenAI tools. It's not a product announcement. It's a captive demand mechanism dressed up as a company.

The CFO went to the Journal saying OpenAI wasn't ready to meet public reporting standards. The Deployment Company is one answer to the revenue problem that doesn't require the math to work on its own.

Anthropic announced an identical vehicle the same day. Same structure. Same timing. Both of them. Simultaneously.

The timeline has accelerated sharply. Evidence wraps Wednesday. Closing arguments Thursday. The jury could begin deliberating by end of week.

Everything the trial has produced — Murati's "No," Brockman's journals, Zilis's texts, Sutskever's disappearing emails, the Cerebras undisclosed stakes, the two sets of numbers, the CFO going to the Journal — is now sitting in the record around him before he says a single word.

His turn.

Read the terms. They're more honest than the marketing.
