- Trade was placed on Kalshi
- Trade arrives as prediction market operators are wooing more business from professional investors
- It involved the outcome of an upcoming California Air Resources Board (CARB) auction
The first confirmation of prediction markets’ potential utility to institutional market participants is here with Greenlight Commodities laying claim to the first ever institutional-level trade in the still nascent history of yes/no exchanges.
Houston-based Greenlight, an introducing broker regulated by the Commodities Futures Trading Commission (CFTC) — the same regulator overseeing prediction markets — said it structured the contract, worked with counterparties and coordinated with Kalshi to bring the trade from concept to reality to finalization.
The milestone marks a new phase for event contracts and prediction markets: institutional block orders are now here,” according to a statement issued by Greenlight. These transactions can be facilitated through the same established regulatory framework used across traditional wholesale commodities markets, including NFA registration, CFTC market oversight, and execution through designated contract markets (DCMs) and derivatives clearing organizations (DCOs), like Kalshi and other regulated exchanges.
The trade occurred between a Houston hedge fund and Jump Trading Group, one of the largest providers of liquidity to prediction markets as well as an investor in Kalshi and Polymarket.
Trade Details
The transaction facilitated by Greenlight, which was identified as an opportunity by Montauk Capital, centers around an upcoming carbon credits auction of the California Air Resources Board (CARB).
Under California’s onerous cap-and-trade program, companies must purchase carbon allowances to emit greenhouse gases. CARB holds related auctions on a quarterly basis. California carbon allowance prices can be volatile and auction volume for the 2024 and 2026 vintages is north of 195.1 million, indicating there’s ample opportunity for institutional traders to provide more accurate views on carbon pricing.
“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. The structure enabled a defined-risk position tied to a specific, measurable outcome,” adds Greenlight in the statement.
Jump Trading Group was on the other side of the trade, providing liquidity, price discovery and “institutional scale.”
Greenlight Trade May Be Start of Something for Kalshi
It’s just one trade, but the Greenlight Commodities transaction may be the start of something more substantial for Kalshi as the largest prediction markets operator continues efforts to broaden its appeal to institutional market participants.
Kalshi is taking various steps in that direction. Last month, the company won approval from the National Futures Association (NFA) to offer margin trading to professional clients.
Efforts such as those are viewed as central to expanding prediction markets’ use cases, increasing participation among professional traders and reducing yes/no exchanges’ dependence on sports event contracts.
