Claude Code gains community-built prediction market integrations for Polymarket and Kalshi
A Model Context Protocol (MCP) skill listed on MCP Market lets Claude Code query real-time odds from both Polymarket and Kalshi, covering election probabilities and sports markets. Separately, a developer published an MCP server connecting Claude to Kalshi through DFlow on Solana for programmatic yes/no contract trading. A Reddit user also described a personal MCP integration linking Claude Code to a Polymarket trade database spanning 72 million trades and 1.5 million wallets. None of the projects are official Anthropic or platform partnerships; all are community-built tools positioning Claude Code as a frontend for prediction market data and execution.
Kalshi and Polymarket now face the same API-native automation race that equities markets ran a decade ago. Any platform without MCP-standard tooling risks losing quant developers to competitors already wired into Claude-assisted execution stacks.
Polymarket's AI-assisted developer workflow and Kalshi's Solana-based automation layer join DRW, Wintermute, and IMC in building prediction market infrastructure this quarter, as three new integrations in five days turn event-contract platforms into programmable execution venues.
