Taylor Swift Wedding Sparks $5 Million Betting Frenzy as Madison Square Garden Venue Pays Out

3 articles · Updated · Hollywood Reporter · Jul 3

$5 million-plus in wagers piled into Kalshi and Polymarket as Taylor Swift's wedding began, with more than $2 million reportedly backing Madison Square Garden as the venue at 84 cents for a $1 payout.
Kalshi and Polymarket turned nearly every wedding detail into a market, from groomsmen and bridesmaids to guest appearances by Selena Gomez and Justin Trudeau, with lower-probability bets drawing attention as potential value plays.
Kalshi says it typically verifies outcomes through source reporting within 12 hours and pays about three hours later, while Polymarket uses a proposer-and-challenge process that can stretch to days if disputes go to token-holder voting.
The markets rely on consensus reporting from major outlets to confirm outcomes, underscoring how a private celebrity event with an estimated $25 million price tag became a public trading spectacle.
