Polymarket US registered $2.72 billion in notional trading volume last week, marking a sharp surge in activity on the decentralized prediction market.

The notional volume reflects the total value of all open positions and settled trades across the platform's event-based markets. Polymarket uses automated market makers to provide liquidity for prediction shares, allowing users to take positions on future event outcomes and exit before resolution.

The protocol's on-chain architecture settles market outcomes through external data sources or designated resolution agents, providing transparent and verifiable trade execution and payouts.

The nearly 4,400 percent increase from January's $60.8 million signals accelerated adoption for Polymarket US, positioning it as a key player in on-chain derivatives for event contracts.
