Intercontinental Exchange (NYSE owner) added $600M to its Polymarket investment on March 27, bringing total commitment near $2B, alongside plans to purchase up to $40M in Polymarket securities from existing holders. The move comes as rival Kalshi recently raised over $1B at $22B valuation (2x previous mark). Polymarket recently acquired a licensed exchange and clearinghouse, and partnered with Palantir and TWG AI to build trading surveillance for its sports prediction markets.
