A prediction market is a real-money contract that pays $1 per YES share if the stated outcome occurs, and $0 if it does not. The current price is therefore the crowd's probability estimate — set by thousands of traders competing in a live order book, not a bookmaker. PolyGram routes your order into the same Polymarket venue, adds an email-first login and USDC deposits, and settles on Polygon within minutes of the result.
