Meta Platforms Inc.Meta, one of Anthropic's largest customers, is looking to cut its reliance on Anthropic's models as it builds AI capability in house.

Anthropic was weighing the release of a new AI model to counter OpenAI's momentum since the September 3 launch of GPT-6 Astra, Reuters reported, citing three sources. The deliberations came days after CEO Dario Amodei warned that "we must slow the pace at which we improve the capabilities of AI models," and sources said Anthropic was still evaluating the new model's safety profile, with the timing question tangled up in the company's push toward an IPO. GPT-6 Astra accounted for about 13% of enterprise AI spending tracked by corporate expense platform Ramp, compared with roughly 8% for Anthropic's Claude Fable, and developers on OpenRouter spent more on OpenAI's models than Anthropic's last week, the first time that had happened in over two and a half years. Meta Platforms, one of Anthropic's largest customers, was also looking to cut its reliance on Anthropic's models as it builds out more AI capability in house, people familiar with the matter said. On the IPO itself, Anthropic's annualized revenue run rate reached $65 billion by the end of July, up from about $9 billion at the end of 2025, and the company was projecting roughly $190 billion to $200 billion in revenue by 2028; two people familiar with the matter said Anthropic could push its listing past November's US midterm elections, a further slip from the mid-October marketing start it had previously targeted. OpenAI, meanwhile, is also not rushing to public markets in 2026, with CEO Sam Altman citing AI safety concerns as reason to wait.
