TL;DR
Take-Two CEO Strauss Zelnick said he views AI-assisted game copying as a creative concern, not currently a financial threat to the publisher. His November 9 remarks followed a question about Anthropic’s rule against recreating specific games; he did not identify a particular AI product, clone or infringement case.

Take-Two Interactive CEO Strauss Zelnick said AI-assisted copying of games is a creative concern rather than a current financial threat to the publisher, while arguing that AI companies should protect others’ intellectual property as well as their own. In an IGN interview published November 9, he was answering a question about Anthropic’s new Claude Code instruction against recreating specific existing games; he did not accuse either Anthropic or OpenAI of a named infringement or identify a particular game clone.
The exchange took place in a phone interview with IGN managing editor Wesley Yin-Poole, published the evening Take-Two reported results for the quarter ended September 30. Asked about hackers using AI to clone games and the prospect of an unofficial version of Grand Theft Auto VI, Zelnick said: “I don’t think it’s a financial matter, in terms of a threat to our business. I do think it’s a creative matter.” He said Take-Two was focused on protecting its intellectual property.
Yin-Poole then asked about Anthropic’s reported steps to block Claude from reverse engineering games and whether OpenAI should take similar steps. Zelnick replied that companies should protect “their own and everyone else’s” intellectual property, adding that it seemed “ironic” for companies in the IP business to “stomp on someone else’s IP and hope that yours is protected.” The companies’ names were introduced in the question. Zelnick did not specify what conduct he meant by “stomp,” or whether he was referring to model training, users’ outputs or another issue.
Anthropic’s Claude Code instruction, present since version 2.1.317, published November 2, tells the model not to build a recreation of a specific existing game, including one using its name, characters, art, music, levels or look, even if presented as renamed or original, a policy issue also discussed in AI game cloning. Anthropic grounds the instruction in its usage policy against infringing third-party IP. OpenAI’s usage policies also bar attempts to infringe others’ intellectual property. The source review found no game-specific instruction in the open-source code of OpenAI’s Codex CLI.

Prompt in, game out: where the line runs
Three example requests (illustrative, not real cases) and what each vendor’s published rules say about them.
“An original racing game with my own art”own idea, own assets
Rule text: build original games and games from the user’s own designs and assets
Nothing in the published usage policies against it
“A heist game with mechanics like [a named hit]”a game named as a reference
Builds an original game in that genre, per Anthropic
No game-specific instruction in the Codex CLI code
“Rebuild [a specific game], just rename it”a copy under a new name
Covers its name, characters, art, music, levels or look; offers to build something similar
Usage policies bar attempts to infringe IP; no game-specific rule found
Outside the tools: Take-Two says it relies on its own “technical defenses” and “legal activities”. Copyright and trademark law apply whichever tool writes the code.
The requests are our own illustrations. The rows summarize published rules, not tests of how the tools behave. ChatGPT’s and Codex Web’s server-side instructions are not public.

Why Game Studios Are Watching AI Rules
For developers and publishers, the exchange highlights a practical distinction: stated platform rules are not the same as a guarantee that users cannot generate or distribute infringing material. Anthropic’s instruction expressly addresses recreation of a particular game, while OpenAI’s cited policy sets a broader IP restriction. Neither policy, by itself, establishes how consistently a system will refuse requests or how a suspected infringement would be handled.
Zelnick also framed the exposure in two ways. He said copying did not currently threaten Take-Two’s finances, but described it as a concern for the creative work and the intended player experience. On the company’s earnings call, he said piracy would become “more of a challenge” and that Take-Two was enhancing its technical defenses and legal activities. That makes the issue relevant to studios weighing platform safeguards, enforcement and the potential effect of unauthorized copies—not just to AI companies.
The Interview Behind the Headlines
Some coverage characterized Zelnick’s comments as a direct callout of Anthropic and OpenAI. The interview transcript is narrower: the interviewer named both firms and asked whether OpenAI should follow Anthropic’s step. Zelnick responded with a general principle and a criticism framed as irony, without citing a specific instance of either company enabling a clone.
The question also used the phrase “reverse engineering,” while the published Claude Code instruction concerns recreating a specific existing game. Those are related but not identical descriptions. On the earnings call, an analyst asked about AI-assisted reverse engineering and decompilation. Zelnick said Take-Two’s business had historically been insulated from piracy by file sizes, technical complexity and server connections, while acknowledging that piracy could become more challenging. He said the company was responding with technical defenses and legal measures.
“I don’t think it’s a financial matter, in terms of a threat to our business. I do think it’s a creative matter.”

What the Policies Do Not Settle
The remarks and policy language do not establish whether a Take-Two game has been cloned using Claude, ChatGPT or another AI system. Zelnick named no case, product or user, and the supplied material provides no evidence of a specific infringement. It also remains unclear what he meant by “stomp on someone else’s IP.”
The available policy descriptions do not show how either company evaluates borderline requests, enforces its rules in practice or responds to a reported game clone. No public response from Anthropic or OpenAI to Zelnick’s remarks was identified in the source material through 21:30 UTC on November 14. The policy and response picture may change after that point.
Policy Enforcement and Studio Defenses
The next developments to watch are whether Anthropic or OpenAI publicly address Zelnick’s comments, and whether either company provides more detail about safeguards for requests involving existing games. For developers, the immediate questions are how platforms apply their published IP policies and what remedies are available when potentially infringing outputs appear.
Take-Two has said it is strengthening technical defenses and legal activity, but the source material does not give a timetable, specific measures or a further milestone. The company’s comments describe its current approach; they do not confirm that a particular AI clone has been detected or that a legal action is underway.
Key Questions
Did Zelnick accuse Anthropic or OpenAI of cloning a Take-Two game?
No specific accusation was made. The interviewer named the companies, and Zelnick responded with a general statement about protecting intellectual property. He cited no game, product or infringement case.
What does Anthropic’s Claude Code rule say about games?
The instruction says Claude Code should not build a recreation of a specific existing game, including its name, characters, art, music, levels or look, even if it is renamed or described as original. The source material dates the instruction to version 2.1.317, published November 2, 2026.
Does OpenAI have a game-specific rule?
OpenAI’s usage policies prohibit attempts to infringe others’ intellectual property. The source review found no game-specific instruction in the open-source code of its Codex CLI; that finding does not establish whether other safeguards exist elsewhere.
Does Take-Two say AI clones are a financial threat?
No. Zelnick said he did not view the issue as a financial threat to the business at that time, but called it a creative concern. On the earnings call, he also said piracy would become more challenging.
What is still unknown?
The source material does not identify a confirmed AI-generated clone of a Take-Two game, explain precisely what Zelnick meant by “stomp on” IP, or detail how Anthropic and OpenAI enforce their policies in individual cases.
