Banks are eyeing the betting game: Prediction markets get serious

Big banks smell money in prediction markets—places where people bet on real-world events like election outcomes or sports results. Jamie Dimon, CEO of JPMorgan, casually mentioned his firm might jump in, but ruled out betting on sports or politics. Goldman Sachs is already deep in talks with leading prediction platforms, sending teams to meet their founders and learn the ropes. Prediction markets used to be a quiet corner of finance, run by just Polymarket and Kalshi. Now, crypto companies like Coinbase and Robinhood have joined the game, making it easier for regular people to place bets. The market has exploded in size and value, with Polymarket reaching a $20 billion valuation and Kalshi hitting $22 billion after fresh funding.The two platforms operate very differently. Polymarket runs on blockchain tech, using smart contracts to settle bets automatically once events conclude. Kalshi, on the other hand, works like a traditional exchange, matching orders centrally and settling trades the old-fashioned way. It’s unclear whether big banks will copy this tech or stick to familiar systems. Regulation is the big unknown. U. S. rules on what kinds of bets can be placed—and how they’re classified—are still being shaped. Until the legal dust settles, banks like JPMorgan and Goldman Sachs will likely hold back, waiting to see how the game is played before making their move.
