Polymarket Us

liveMarketsLegalTechnology

Polymarket US MCP — market data for Polymarket US (polymarket.us), the CFTC-regulated, US-licensed prediction-market exchange operated as a SEPARATE venue from the offshore Polymarket platform. It has its own markets, its own slugs, and its own settlement process — a slug from one venue does not resolve on another, and this pack never mixes them. For the offshore venue see the `polymarket` pack; for the other CFTC-regulated US venue see the `kalshi` pack.
