Taylor Swift Super Bowl Show Odds Jump After Engagement Announcement

Taylor Swift’s engagement to Kansas City Chiefs tight end Travis Kelce has triggered fresh speculation about next year’s Super Bowl halftime act.

On the prediction market, Kalshi, trading activity shifted heavily in her favor, with 61% backing her to perform at Levi’s Stadium in Santa Clara. That placed her well ahead of Post Malone at 16% and Metallica at 11%.

Her recent appearance on New Heights, the podcast hosted by Travis and Jason Kelce, also drew attention. During the episode, she discussed baking sourdough bread, something often associated with San Francisco culture, and repeatedly highlighted the number 47. 

Observers quickly pointed out that the local team’s mascot is “Sourdough Sam” and that Levi’s Stadium, which will host Super Bowl LX, was also the site of the 47th stop on her Eras Tour.

Swift, 35, has been linked to halftime show rumors for years, but was previously considered unlikely due to her Coca-Cola sponsorship, as Pepsi held the naming rights to the event. When Apple Music took over in 2022, the company invited her to appear at Super Bowl LVII. In that game, Kansas City defeated Philadelphia, but she declined to focus on touring and re-recording her albums.

Although she has never been the headline performer, Swift has been visible at recent Super Bowls in her role as Kelce’s partner. She has been seen celebrating on the field after Chiefs wins and sitting in the stands during last season’s loss to the Eagles.

Polymarket and Kalshi feud ramps up

The surge in interest in Swift's potential performance highlights the growing role of prediction markets, where entertainment outcomes trade alongside politics and sports. Within that sector, Polymarket and Kalshi, the two largest platforms, have become direct rivals, with Donald Trump Jr. now an advisor to both. 

Trump Jr. joined Kalshi as a strategic advisor in January, and this week, he took a similar role at Polymarket after his firm, 1789 Capital, made a strategic investment in the exchange.

His dual involvement has raised eyebrows, particularly after he described Polymarket as "the largest prediction market in the world" and stressed the importance of US access to it. Kalshi, which he had praised earlier this year after the platform's accurate forecast of his father's election win, has not commented publicly on his shift.

Competition between the two exchanges has intensified as Polymarket reopens to US users through QCEX, a licensed exchange it acquired earlier in 2025. In 2022, the Commodity Futures Trading Commission (CFTC) fined Polymarket $1.4 million and ordered it to block US customers. Its re-entry now pits it directly against Kalshi, which the CFTC also regulates.
