Reddit's User Agreement can bind Anthropic, a judge rules, and the meter is running

Three claims survive, and they are the expensive ones

Judge Harold Kahn of the San Francisco County Superior Court has overruled Anthropic's demurrer↗ and sent three of Reddit's five claims toward trial: breach of contract, interference with contract, and unfair competition under California law ¹. The order is dated 17 September and was filed the next day ¹. A demurrer decides no liability, only whether allegations state valid claims; Kahn held that three of Reddit's do ¹³.

The two claims trimmed as too vague, unjust enrichment and trespass to chattels, can be refiled by 16 October ¹. Reddit sued in June 2025, saying Anthropic trained Claude on its users' comments without a license ¹.

The defense was that nobody clicked agree

Anthropic's bet was that Reddit's User Agreement is "browsewrap," a page no one affirmatively accepts and so binds no one↗ ¹. Kahn rejected it, finding Anthropic's "conduct sufficient to infer actual knowledge of the terms of the User Agreement↗ and to form an implied-in-fact contract with Reddit" ². The alleged conduct is blunt: more than 100,000 scrapes after Reddit's chief executive publicly called out the practice ¹.

Anthropic also framed the claims as copyright in disguise, which would have opened the fair-use door; the judge held each surviving claim needs an extra element beyond unauthorized copying ²³. Even Claude's admission that it could not say whether scraped user data had been deleted counted toward the interference claim ³.

Terms of service, now with teeth

The reach runs past Reddit. Terms of service can hand any website operator a contract claim beyond copyright, which is the part every content holder with anti-scraping rules is watching ³.

The free-data era did not end with a copyright verdict. It ended with a terms-of-service page being treated like a lease.

The price list already exists

Reddit sells what Anthropic allegedly took. Google's 2024 license is worth about $60 million a year↗ ⁴⁶, OpenAI has its own ⁵⁶, and together the deals run to roughly a tenth of Reddit's revenue, expiring in 2027 ⁶. Both are up for renewal while Steve Huffman says he is "still looking for that win-win↗" ⁵, and the bull case sees hundreds of millions in new profit from renegotiation ².

Reddit negotiates from strength: at least 61 percent revenue growth year over year in each of the past eight quarters↗, profitable in all of them ⁷. RDDT rose 4.5 percent to $157.64 on the first trading day after the order, a rare lift for a stock down 30 percent this year ².

The bill lands on a $2 trillion ledger

Whatever the taking gets priced at, the bearer is about to go public. Anthropic's prospectus shows a $42 billion net loss for 2025↗, revenue up twelvefold to nearly $4.6 billion, and $518 billion in planned cloud and infrastructure spending, in a sale that could value it above $2 trillion and raise as much as $100 billion ⁸⁹. The Reddit claim sits in that stack beside the Pentagon's temporary blacklist, blocked by a US judge in August ⁸.

The template for settling is already signed

Anthropic said in June 2025 it disagreed with the claims and would "defend ourselves vigorously" ². The likely exit is still the Google template: a retroactive payment for what Claude already learned, then a license. That is a prediction, not a holding: the lawyer Kirk Sigmon expects exactly that settlement, with the rivals already paying as the pricing evidence ².

The next dated marker is 16 October, when Reddit refiles its trimmed claims ¹. Discovery is where a decade of free data learns its price.
