John Gruber (Daring Fireball) investigated Y Combinator's OpenAI stake, determining it's approximately 0.6% — worth over $5 billion at the $852B valuation. Gruber argues that when Paul Graham is quoted as an Altman character reference (as in the New Yorker), the billions in personal financial interest should be disclosed. Simon Willison shared this on May 5, calling it 'devilishly difficult information to obtain.'
