Kalshi, a US-based futures trading platform, has introduced an AI-powered tool named "Harrison" to enhance risk assessment in prediction market contracts. The tool, based on Anthropic's Claude model, is designed to scrutinize contract wording and evidence sources, particularly for markets involving elections and sports, to preemptively identify potential vulnerabilities. Harrison aids in the design and stress testing of over 500 market templates, aggregates news, analyzes competitor contracts, and suggests new market opportunities and liquidity incentives. Traditionally, Kalshi requires two individuals to review new contract rules, a process that takes 1-2 hours. The AI tool also compares its findings with human judgments during market settlements, providing an additional compliance layer, especially for complex events like Supreme Court rulings.
