Kalshi CEO Tarek Mansour cited a Bloomberg report saying that Kalshi has completed its first tailored block trade. According to Odaily Planet Daily, Jump Trading provided liquidity support for the trade. The transaction was matched this month by Greenlight Commodities, executed on behalf of a Houston-based environmental hedge fund that is seeking exposure to a contract that tracks whether “a specific price will be realized” in carbon emissions allowance auctions held in California in May. Mansour said that institutional applications of prediction markets could amount to a $10–15 trillion market, and that its growth potential may be even larger, depending on how widely they adopt products that are currently exclusive to Wall Street.
