A Foundry/Solidity prediction-market stack with PredictionMarket (an LMSR AMM), MarketFactory, and AgentAccount, the last enforcing session-key spending caps with per-call and lifetime USDC limits and settling in Arc native USDC. A Python agent reads market state via web3 from the Arc factory, queries Polymarket Gamma and Claude (via OpenRouter) for calibrated probability, sizes positions with fractional Kelly, and in --live mode signs and broadcasts buy transactions including through AgentAccount.execute(). The autonomous account system, USDC-native gas economics for small consumer positions, and transparent per-decision reasoning logging are offered as reusable reference implementations.
