The article discusses Y Combinator's stake in OpenAI, which is reportedly around 0.6%, worth over $5 billion at OpenAI's current valuation. This stake creates a potential conflict of interest, particularly for Paul Graham, Y Combinator's co-founder, when commenting on Sam Altman's trustworthiness. The article suggests that this conflict of interest should have been disclosed in The New Yorker's investigative piece on Altman. The exact size of Y Combinator's stake in OpenAI was previously unknown, but the article cites an insider source for the 0.6% figure.
