Greenlight Commodities executes first institutional prediction market trade on Kalshi

Greenlight Commodities has placed what it describes as the first institutional trade executed through a prediction market, completing an over-the-counter transaction on Kalshi between a Houston-based environmental hedge fund and Jump Trading Group.

The Houston-based introducing broker, which is regulated by the Commodity Futures Trading Commission (CFTC), said it structured the contract, sourced counterparties, coordinated with the exchange, and oversaw execution of the transaction.

The trade was linked to the outcome of the upcoming May 20, 2026, California Air Resources Board Joint Auction #47, where companies purchase carbon allowances required to emit greenhouse gases under California’s cap-and-trade system.

The transaction signals a new use case for prediction markets, which have largely been associated with retail participation and event-based contracts tied to sports and politics.

“The milestone marks a new phase for event contracts and prediction markets: institutional block orders are now here,” the company said in a statement.

According to Greenlight, the transaction was completed under an existing regulatory structure that includes National Futures Association registration, CFTC oversight, and execution through designated contract markets and derivatives clearing organizations such as Kalshi.

Carbon auction contract

The trade opportunity was initially identified by Montauk Capital, which Greenlight said recognized institutional demand for event contracts tied to environmental commodities.

Instead of trading carbon allowances directly, the hedge fund used a Kalshi event contract designed specifically for the auction to take a position on the clearing price.

“Rather than trading the underlying carbon allowances directly, the hedge fund used a Kalshi event contract, created and certified for this purpose, to express a view on the auction’s clearing price,” Greenlight said. “The structure enabled a defined-risk position tied to a specific, measurable outcome.”

On the other side of the transaction, Jump Trading Group provided liquidity for the trade.

Greenlight said California carbon allowance prices can fluctuate significantly and noted that auction volume for the 2024 and 2026 vintages exceeds 195.1 million allowances, creating trading opportunities tied to pricing expectations.

Institutional expansion efforts

John Conlon, director at Greenlight Commodities, said the transaction could signal increased institutional participation in prediction markets.

“This is the shot heard round the world for institutional prediction markets. We have been saying for months that event contracts were coming to an institutional scale. Today we proved it. First movers win, and today every party on this trade is a first mover,” Conlon said.

“What we proved today is that risk touches every part of the world. Every business. Every person. And now there is a simple, pure, institutional hedge for it. There is not a single event on earth that cannot be hedged, almost perfectly, with an event contract. Today was day one,” he added.

Conlon also credited Montauk Capital for identifying the market opportunity early.

“Montauk identified this opportunity early and understood where the market was heading,” Conlon said. “Today’s transaction reflects that foresight and the value of backing emerging market infrastructure before consensus forms.”

Greenlight’s team handled onboarding, compliance checks, regulatory processes, and coordination between counterparties to complete the trade.

The transaction comes as Kalshi continues efforts to attract more professional traders. Last month, the exchange received approval from the National Futures Association to offer margin trading to professional clients, a move viewed as part of its push to expand institutional participation and reduce reliance on sports-related event contracts.

“As more institutions seek new ways to express views, hedge exposure, and access event-driven opportunities, prediction markets are evolving into a serious component of modern market structure,” Conlon said. “This first block trade is only the beginning.”
