Claude vs ChatGPT, Priced: A $965B Challenger Against an $840B Incumbent
The comparison table, from the board
Claude vs ChatGPT is usually argued on features. On this site it is argued on the figures both makers have actually published or had reported. Latest reported valuation: Anthropic $965 billion (Series H, May 2026) against OpenAI $840 billion (February 2026 round, announced as $110 billion raised at a $730 billion pre-money value). Reported valuation points on the board: six each, Anthropic's running from $4.1 billion in May 2023, OpenAI's across the same span. Latest reported revenue: OpenAI $20 billion annualized (December 2025, reported by Reuters) against Anthropic $16.8 billion annualized for Q3 2026, a single quarter the company disclosed to investors. Public status: Anthropic has filed its S-1 (October 26, 2026, Nasdaq: ANT, price range pending); OpenAI remains private.
Where each side leads
On the last private mark, the challenger leads: $965 billion is the highest valuation on the board, printed three months after OpenAI's round. On revenue run-rate, the incumbent leads: $20 billion against $16.8 billion, though the two figures are not measured the same way, one a reported December 2025 annualization and the other a company-disclosed single quarter nine months later. On trajectory, Anthropic's six marks climb without a flat round in the set the board records, and its next price will be set by public markets rather than by another private negotiation.
The verdict, by what you are pricing
If the question is which company public investors will get to price first, it is Claude's maker, and its private marks stop updating the day the IPO prices. If the question is which business is larger today on reported revenue, it is ChatGPT's maker. And if the question is which assistant to use, this table deliberately does not answer it; it answers the prior question of what each company is worth while the argument runs.
Watch both lines
The Tickers for the Tickerless compare view holds both lines on one chart, every point dated and sourced, and it will mark the day Anthropic leaves the board. The filing itself is walked through in the Anthropic S-1 article on this blog, and questions about the wider dataset route through the contact page.
