The exchanges bought the bookies. Now comes the data war
Intercontinental Exchange, parent of the NYSE, completed a $2 billion commitment to Polymarket in March, $1 billion in October plus a fresh $600 million, with the platform now discussing new funding near a $15 billion valuation.Kalshi raised more than $1 billion this spring at a $22 billion valuation, roughly doubling in months, on volumes that reached $31.5 billion in June against Polymarket’s $10.8 billion, with fee revenue estimates running from $850 million to $1.5 billion annualized.The tell is the deal structure: ICE bought global distribution rights to Polymarket’s event data and launched institutional probability feeds within months, chairman Jeffrey Sprecher framing the stake as a new layer of financial intelligence, not a venture flyer.The consolidation is visible everywhere: the rival CEOs jointly backed a $35 million VC fund for the sector, Kalshi struck institutional distribution through Tradeweb, Robinhood’s event contracts out-earned its crypto business, and banks project the industry toward $10 billion in annual revenue by 2030.All of it is happening against maximal legal hostility: at least seven bills targeting the category in 2026, a bipartisan act to ban sports contracts outright, and the 50-state jurisdictional war this publication has mapped, a contradiction the valuations are pricing as temporary.
