Ara Kharazian, who runs the Ramp AI Index, posted on 2026-09-16 that as of this week GPT-6 Astra takes 13% of enterprise AI spend versus Fable's 8%, and that OpenAI's growth is coming from shifts off GPT-5.6 Sol, off some Anthropic models, and from net-new usage. He reads it as Anthropic's "pace the frontier" position costing it frontier adoption. That cuts against the September 9 Ramp index, which had Anthropic ahead on breadth at 43.8% of U.S. businesses paying for it versus OpenAI's 39.8% — two different questions, how many companies buy you versus how much of the frontier budget you get, and they now point opposite ways.
