Altman's Integrity at Issue in OpenAI Lawsuit as Former Directors Testify

This article is a translation. Read the Japanese original

OpenAI CEO Sam Altman was questioned in a California federal court on 2026-05-13.

Plaintiff's attorney Steve Morrow pointed out that Altman had an economic interest in OpenAI through Y Combinator funds.

Altman explained the circumstances behind his 2023 congressional testimony, where he stated, "I have no equity in OpenAI." He explained that his status as a Limited Partner (LP) at Y Combinator constitutes passive ownership. Morrow pressed Altman on why this point was not disclosed.

The plaintiffs argue that Altman's integrity is one of the central issues. Former OpenAI directors Helen Toner and Tasha Mc collinear testified that Altman had engaged in lying or misleading behavior. Mc collinear stated that there was a "toxic culture of lying" within OpenAI.

The issue of Altman's removal by the board in 2023 was also discussed. Altman questioned whether the primary reason for his dismissal was a lack of integrity, citing the fact that requests for his return arrived the following morning.

OpenAI contends that the current nonprofit board appropriately controls the for-profit arm. Microsoft CEO Satya Nadella described the dismissal turmoil as an "amateurish event." OpenAI board member Bret Taylor testified that they are dealing with Altman with integrity.

This lawsuit questions whether OpenAI's structure aligns with its mission. Specifically, the focus is on whether the nonprofit board can exercise true control over the for-profit sector. Musk's side has presented the 2023 dismissal turmoil as evidence that Altman's influence outweighed that of the board.
