Anthropic has updated Claude's usage policy to prohibit users from employing the AI tool to replicate specific existing video games. Claude may still assist in developing original games, games of particular genres, and games based on users' own designs and assets; however, even if a user renames a replicated game or passes it off as original, such use is not permitted. Company representatives said the move is intended to prevent Claude from being used to infringe on others' game intellectual property, and that related compliance projects are, in principle, unaffected; the rules will continue to be adjusted to define an appropriate scope of restrictions. The policy change comes as a growing number of hobbyist projects use AI to process large volumes of game code and create browser-based versions, with AI-developed browser-playable versions of several well-known games already having surfaced. Anthropic has previously faced repeated intellectual property disputes: in 2025, it agreed to a $1.5 billion settlement in a class-action lawsuit brought by roughly 500,000 authors who accused it of using copyrighted material to train its AI models, and the Elvis Presley estate subsequently filed a similar suit against the company.
