OpenAI spending overtakes Anthropic on OpenRouter for the first time in 2.5 years

FinanceYF5 · x · 2026-09-16

FinanceYF5 notes a reversal on OpenRouter not seen in about 2.5 years: user spending on OpenAI models has surpassed Anthropic's.

The caveat: this reflects spending on one aggregator platform, not overall AI market share. Still, OpenRouter is widely watched as a proxy for developer model preferences, and the flip suggests OpenAI's recent models have regained developer mindshare.
