02:18 PM EDT, 04/30/2026 (MT Newswires) -- Elon Musk testified that he never had a written agreement governing the terms of his early donations to Microsoft ( MSFT ) -backed OpenAI, telling a federal court that he relied on the company's nonprofit charter rather than a formal contract, Bloomberg reported Thursday.

Musk is suing OpenAI and CEO Sam Altman, alleging the company abandoned its original nonprofit mission and pivoted toward profit in partnership with Microsoft ( MSFT ). OpenAI denies the claims and says Musk's lawsuit is intended to undercut a competitor as his own AI startup, xAI, grows.

Under questioning, Musk said he did not have representatives prepare documents outlining conditions for the funds he committed when OpenAI launched in 2015, the report said. At the time, the nonprofit said Musk had pledged up to $1 billion in phased donations, and Musk now says he has contributed $38 million "in strict monetary terms," according to the report.

OpenAI did not immediately respond to a request for comment from MT Newswires.
