Bettors are placing wagers on almost every detail of Taylor Swift and Travis Kelce's upcoming marriage.

The New York Post noted that the best sports betting apps and best prediction markets have launched a variety of specials, starting with whether their engagement announcement will become Instagram's most-liked post.

The photo currently has 35 million likes, but it would need to surpass Lionel Messi's 2022 World Cup trophy post, which has 74 million likes. On Polymarket, the odds of Swift and Kelce overtaking Messi by the end of August stand at 50/1.

Markets are also open on the day the couple will marry. Polymarket lists 10/1 odds for a wedding by Oct. 31 and 7/1 for one by December 31. Analysts estimate that the chances of a wedding before the end of the year are around 12%, with 2026 and later considered the most likely timeframe.

Other wagers include whether Swift will keep her last name, offered at 12/1, and if the pair will marry on the 13th, her favorite number, which is heavily favored at 1/4 offshore.

Engagement sparks Super Bowl speculation

Swift's engagement has reignited speculation about her potential role as the headline act for next year's Super Bowl halftime show. On prediction platform Kalshi, trading shifted sharply in her favor, with 61% backing her to perform at Levi's Stadium in Santa Clara. That figure placed her ahead of Post Malone, at 16%, and Metallica, at 11%.

Her appearance on New Heights, the podcast hosted by Travis and Jason Kelce, fueled further speculation. She discussed baking sourdough bread, a symbol often tied to San Francisco, and highlighted the number 47 several times. They made comparisons of those remarks and Levi's Stadium, where her 47th Eras Tour show was taking place, and the San Francisco 49ers mascot, Sourdough Sam.

Although she has never headlined the half-time show itself, Swift's name comes up in rumors every year. Her Coca-Cola contract was incompatible with Pepsi's naming rights, yet Apple Music's acquisition of it in 2022 changed that.
