Polymarket completes first institutional block trade as prediction markets target larger investors

Institutional participation in prediction markets took another step forward after Polymarket completed its first block trade, a six-figure transaction between digital asset brokerage FalconX and Anera Labs, a trading technology startup building a clearinghouse for AI risk.

The trade involved a contract linked to the Ornn Compute Price Index, a benchmark that tracks rental pricing for Nvidia's H100 GPU chips.

While retail traders have driven a rise in prediction market volumes over the past year, operators are increasingly pursuing institutional activity as another source of growth. Polymarket said FalconX will serve as a dedicated market maker for future block trades on its platforms.

“Prediction markets are emerging as one of the most powerful venues for institutional block trades, and this transaction is proof,” said Brooke Rizzetto, Head of Institutional Liquidity at Polymarket, in a statement. “Seeing an institutional counterparty use Polymarket to hedge real GPU compute exposure at scale is exactly the future we have been building toward.”

Block trades are large transactions negotiated privately between parties and typically executed outside public markets to limit price volatility. Such transactions are commonly used in equity markets by institutional participants.

“This transaction highlights the accelerating demand for financial infrastructure in the compute space,” said FalconX Global Co-Head of Markets Ravi Doshi in a statement. “We’re proud to collaborate with pioneers like Polymarket to deliver deeper liquidity and clearer price discovery to this crucial, rapidly evolving commodity market.”

Competition for institutional order flow

The announcement comes slightly more than a month after Kalshi, Polymarket's chief rival, completed what it described as the first block trade on a prediction market platform.

However, Polymarket noted its transaction was the first institutional prediction market trade conducted on-chain. The company's international platform operates on the Polygon blockchain.

The international exchange operates independently from Polymarket's US platform, which launched in December. The company had been prohibited from operating in the United States in 2022 after regulators determined it had not properly registered.

In July, the Commodity Futures Trading Commission and the Department of Justice ended their investigations into Polymarket without filing charges. The Commodity Futures Trading Commission regulates the company's US platform.
