Kalshi's record $17B month tied to new AI 'Harrison' built on Claude

Published Jun 15, 2026

Kalshi quietly built a custom AI named 'Harrison' on Anthropic's Claude to stress-test prediction market contracts amid a record-breaking $17 billion month. The AI system operates as a behind-the-scenes tool for the CFTC-regulated prediction market platform.

Why this matters?

Deploying a proprietary AI for contract design at scale during a record volume month suggests Kalshi is streamlining market creation in ways that could become a competitive edge against Polymarket and other rivals.
