Kalshi completed its first block trade with liquidity from Jump Trading to bring prediction markets closer to traditional finance tools.
Kalshi, a U.S.-regulated prediction markets platform overseen by the CFTC, for the first time executed a bespoke block trade where Jump acted as the market maker on the other side.
According to a Bloomberg report, the transaction was arranged by Greenlight Commodities for a Houston-based environmental hedge fund. Instead of using a standard listing, the trade relied on a custom-built contract tied to the clearing price at a May auction for carbon allowances in California.

Small Ticket, Familiar Structure
The size came in at a six-figure sum. That’s small compared to traditional block trades, where single transactions in equities or commodities can easily exceed $10 million and often run into the $50 million-$100 million range depending on liquidity conditions.
According to Bloomberg, the deal was cleared through Kalshi’s own futures clearing setup.
- Jump Trading already has exposure to Kalshi, holding a small equity stake tied to its role as a liquidity provider across the platform’s contracts. The firm is also reportedly an investor in Polymarket, a key rival in the prediction markets space.
For now, Kalshi remains heavily retail-driven. Typical trade sizes on prediction platforms often range from under $100 to a few thousand dollars, far below institutional ticket sizes. But moving into block trades starts to open the door for funds that need to deploy larger chunks of capital in a single go.
Early Signs of Scale on Kalshi
Prediction markets remain tiny compared to global financial markets. For context, foreign exchange markets alone see about $9.6 trillion in daily trading volume, while OTC interest rate derivatives add roughly $7.9 trillion per day, according to data from the Bank for International Settlements.
A Jump representative said in a statement shared with Bloomberg that demand from institutional players is expected to expand across a wider range of contracts, signaling early interest even if volumes remain limited for now.
