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.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
