OpenAI's new model, GPT-6 Astra, has captured approximately 13% of enterprise AI spending within two weeks of its launch, Reuters reported. OpenRouter data shows OpenAI's share rapidly climbing to about 65%, surpassing Anthropic (approximately 35%) for the first time. Facing fierce competition and loss of enterprise market share, Anthropic is evaluating the possibility of an early release for its new model, and its IPO plans may be postponed until November.
