Kalshi CEO Tarek Mansour announced on X, citing Bloomberg, that Kalshi has completed its first custom block trade, with liquidity support from Jump Trading. According to Odaily, this transaction was facilitated by Greenlight Commodities this month on behalf of a Houston-based environmental hedge fund. The fund sought exposure to a contract tracking whether a specific price would be achieved in California's May carbon emissions allowance auction.
Mansour noted that the institutional application of prediction markets could represent a $10-15 trillion market, with potential for further growth depending on how widely these products, currently exclusive to Wall Street, are adopted.
