Y Combinator’s Stake in OpenAI

A report says Y Combinator likely owns about 0.6% of OpenAI, a stake that could be worth more than $5 billion at OpenAI’s $852 billion valuation.

The piece links that financial exposure to Paul Graham’s public comments about Sam Altman and argues it should be disclosed when Graham is cited as a character reference.

The core concern is a potential conflict of interest: YC figures may have a material financial stake in how OpenAI and Altman are perceived.

That disclosure question could shape how readers judge commentary from YC insiders on Altman’s leadership and trustworthiness.
