OpenAI Q3 revenue reportedly rises ~50% to $10B with $10.9B adjusted operating loss, trailing Anthropic's $17B

The Wall Street Journal and The Information report, via The Decoder, that OpenAI's Q3 revenue rose about 50% on the previous quarter to roughly $10B, against $3.9B a year earlier. The adjusted operating loss is reported at $10.9B, with margin improving from -150% to -109%. Anthropic is reported to have earned $17B (+47%) with only a $567M operating loss including stock compensation. OpenAI reportedly cut prices on new models, shifted focus to enterprise and Codex, and hired a new head of sales. None of this comes from filed accounts. The extraction found no primary documents, so every figure rests on leaks and secondhand summary.

If the numbers are right, OpenAI's enterprise push is lifting revenue, but it is still losing about $1.09 for every $1 of revenue, while Anthropic is bigger and close to break-even on this measure. That matters most to investors weighing OpenAI's $1.25T valuation and Anthropic's IPO next week, and OpenAI reportedly has raised under half of its planned $30B. Enterprise buyers and developers gain little directly beyond the signal that price cuts and competition between Codex and Claude Code are likely to continue. The impact is mainly on financing and sentiment, not on what the products can do.

The headline comparison is shaky: the two companies may count revenue differently (gross versus net of cloud partner shares, for example), and the loss figures are not like for like, since Anthropic's includes stock compensation and OpenAI's is "adjusted". The user counts (1.2B weekly, 100M paying) and the $1B ads run rate are reported claims, not audited, and the "50% growth" is a single quarter. The framing of OpenAI "trailing" Anthropic is a narrative built on unverified leaks timed around an IPO.

1. 01Anthropic's IPO filing and prospectus next week: do audited revenue, revenue recognition and operating loss match the reported $17B and $567M?
2. 02Whether OpenAI closes the rest of its planned $30B raise, and at what valuation, given it has reportedly raised under half so far.
3. 03OpenAI's Q4 figures and enterprise metrics (Codex and API usage, sales hires, price cuts): does revenue growth hold while the operating loss margin keeps shrinking from -109%?
