Polymarket, the world's second-largest prediction market by trading volume, today completed the first institutional block trade ever executed on-chain in the prediction-market category — a six-figure transaction between prime broker FalconX and AI-risk clearinghouse AneraLabs that hedges exposure to Nvidia H100 GPU rental prices, the protocol said in a press release.

The trade settled against the Ornn Compute Price Index, a transaction-based H100 rental benchmark developed by Ornn AI Inc. and now distributed on the Bloomberg Terminal.

Polymarket runs $474.6 million in total value locked on Polygon and cleared $127.5 million in 24-hour volume against $917.2 million over the last seven days, per DefiLlama. Settlement of the FalconX-AneraLabs trade is recorded on Polygon as a publicly auditable transaction.
