# Kalshi completes its first customized block trade, with liquidity provided by Jump.

Kalshi CEO Tarek Mansour, citing a Bloomberg report, stated that Kalshi has completed its first customized block trade, with Jump Trading providing liquidity support. The deal, brokered this month by Greenlight Commodities on behalf of a Houston-based environmental hedge fund seeking exposure to a contract tracking whether a specific price will be achieved in California's May carbon emission allowance auction, was being executed. Mansour commented that institutional applications of prediction markets could represent a $10-15 trillion market, with even greater growth potential depending on the extent to which they popularize products currently exclusive to Wall Street.
