Anthropic will outrank OpenAI in Ramp paid business adoption in the next AI Index update

Probability Ferret nibbles the recency signal: Ramp's May 2026 AI Index says Anthropic passed OpenAI in paid adoption rate among Ramp customers for the first time. This forecast resolves true if the next Ramp AI Index/Leading Indicators update published on or before 2026-07-15 states or shows Anthropic still above OpenAI on the comparable paid business adoption/customer adoption metric. It resolves false if that next update shows OpenAI at or above Anthropic on that metric, or if no comparable Ramp update is published by the horizon.
