Brockman Rebuts Musk, Describes Tesla Work
Greg Brockman, a top OpenAI executive, testified in the Musk v. OpenAI trial, disputing Elon Musk’s account of OpenAI’s early history and rebutting claims about the organisation’s corporate structure and his personal commitments. During testimony he revealed that OpenAI expects to spend roughly $50 billion on compute this year and that the organisation has announced plans for more than $1 trillion in AI infrastructure investments over coming years. Musk alleges co‑founders Sam Altman and Greg Brockman diverted OpenAI’s value into a for‑profit arm; OpenAI contends the nonprofit core retains control and that a for‑profit vehicle was necessary to raise large-scale capital. Brockman also described past interactions involving Tesla staff and addressed personal financial questions raised during cross-examination.
High-profile litigation involving OpenAI and Elon Musk may influence governance, public perception and strategic decisions at a major AI platform provider; implications could ripple across AI industry players and funders but it is not a direct AdTech operational or policy change.

Musk vs OpenAI Trial Reveals Control and Donation Dispute
During the second week of the Elon Musk v. OpenAI trial, OpenAI president Greg Brockman testified that Musk pushed the company to create a for‑profit arm and sought “absolute control” over it. Musk previously testified that OpenAI CEO Sam Altman and Brockman deceived him into donating $38 million by promising to keep the organization nonprofit; OpenAI later accepted large investments from Microsoft and restructured to operate a for‑profit subsidiary. The court proceedings have included testimony, diary excerpts and other witness accounts; the trial is occurring as OpenAI plans a public listing. The reporting is an MIT Technology Review analysis republished on t3n and was written by Michelle Kim (published 2026‑05‑11).
Elon Musk Testifies, Contradicts His Own Tweets
Elon Musk testified in a U.S. federal court on April 29, 2026, in a lawsuit he filed challenging OpenAI’s corporate structure, alleging cofounders misled him and effectively “looted the nonprofit.” Under oath he admitted Tesla is not currently pursuing artificial general intelligence (AGI), contradicting a recent post claiming Tesla would be among companies to build AGI. During cross-examination OpenAI’s lawyer William Savitt questioned Musk about his earlier support for moving OpenAI toward for-profit structures, Microsoft’s evolving investment terms, efforts by Musk-linked companies (Tesla, Neuralink) to recruit OpenAI staff, and past donation amounts. The judge limited but signaled continued questioning about safety approaches; additional witnesses expected include Jared Birchall, Stuart Russell and OpenAI president Greg Brockman. The testimony centers on distinctions around capped-profit investor terms and safety implications of OpenAI’s corporate changes.
Musk Cross-Examined in OpenAI Trial
On April 29, 2026, Elon Musk continued testifying in his lawsuit challenging OpenAI’s conversion from a nonprofit to a for-profit structure. During a heated cross-examination by OpenAI attorney William Savitt, Musk said he lacked detailed knowledge of OpenAI’s internal safety efforts and was unsure what “safety cards” are. Musk reiterated that his roughly $38 million in early donations helped found OpenAI and said Microsoft’s reported $10 billion investment was a tipping point that eroded his trust in the organization. The case centers on claims of breach of charitable trust and unjust enrichment; Microsoft is also a named defendant. Judge Yvonne Gonzalez Rogers is overseeing a two-phase trial (liability then remedies). Musk’s testimony is expected to continue, and Jared Birchall is slated as the next witness.
