Rooney commented on the midfield show in the World Cup final, predicting that the market transaction volume will exceed US$5.5 billion.
Wayne Rooney's straightforward evaluation of the midfield show in the first final of the World Cup quickly became popular on the Internet. At the same time, the two major platforms, Polymarket and Kalshi, set a transaction record of US$5.5 billion during the event.
Core Points
Wayne Rooney called the World Cup final halftime show "garbage" on the live broadcast, and the relevant footage spread online within hours. Kalshi traders priced songs and surprise guests for the halftime show in advance, pushing World Cup betting totals above US$5.5 billion. Spain's 1-0 victory over Argentina set a record for the largest forecast market transaction in history.
Comments on Rooney's midfield show
On July 19, Rooney, as a BBC commentator, said at the Metropolitan Life Stadium that the highlight of the show "was when it ended." The 40-year-old former England striker added: "I like a lot of these artists, but I thought the performance was garbage." He told the audience that the performance "didn't excite me at all." Fans responded quickly, with many believing the former England striker spoke the hearts of most Britons.
The 11-minute performance, curated by Coldplay lead singer Chris Martin, brought together Madonna, Shakira, Bulletproof Boys, Justin Bieber, the Bernard Boys and the Muppets Show. FIFA has extended the usual 15-minute intermission to more than 27 minutes to accommodate all of these performances. Spain then defeated Argentina 1-0 in extra time, with substitute Ferran Torres scoring the winner in the 106th minute.
Kalshi's midfield show market
The performance, which Rooney criticized, has been a tradeable event in previous weeks. Kalshi data showed that on the eve of the final, Sabrina Carpenter led the "surprise guest" market with odds of 30%, followed by Post Malone with 24%, and Swee Lee with 19%. Traders believed that the probability of Shakira singing "Dai Dai" was as high as 98%, and her chorus with the Bernard Boy that night confirmed this prediction.
The same market believed that Bieber had a 14% chance of singing "Daisies", but he ultimately chose to sing "Everything Hallelujah". Polymarket's championship contract transaction volume reached US$4.28 billion, and Kalshi's Spain vs. Argentina market attracted US$1.29 billion. Before the start of the game, the total World Cup transaction volume on the two platforms had exceeded US$5.5 billion. Polymarket uses USDC to settle, so most transactions are completed through the cryptocurrency track.
Platform data shows that as of mid-week, the total transaction volume of all World Cup contracts has exceeded US$25 billion. This figure far exceeds the approximately $2 billion in the NBA Finals and the approximately $1 billion in the Super Bowl. These data mark a hot year for Polymarket's championship market, which was launched in July 2025 and has now grown into the largest single contract in platform history, even surpassing the 2024 U.S. presidential election market. In June alone, monthly transaction volume was close to US$11 billion, most of which was driven by World Cup deals.
