§ Polymarket data is read from their public Gamma API as a publicly-available price source. Posterior is independent — not a Polymarket affiliate, not a counterparty, not routing trades there. See /affiliate-disclosure. Below $50k 24h volume, Polymarket's market is too thin to read as signal; those games render the chart with the Polymarket line absent and the sportsbook + model lines only.
