Who will perform at the World Cup final halftime show? — In 2026

These markets ask whether specific artists will perform live at the 2026 FIFA World Cup Final halftime show on July 19 at MetLife Stadium — the first-ever Super Bowl-style halftime show in World Cup history, produced by Global Citizen. A "Yes" resolves if the named artist performs in any capacity, including as a guest; "No" resolves if they do not appear. With the lineup now officially confirmed, most candidates have collapsed toward near-certainty in one direction or another. The confirmed performers are Madonna, Shakira, Burna Boy, BTS, Justin Bieber, conductor Gustavo Dudamel, and the PS 22 Chorus featuring Coldplay. Justin Bieber joined Madonna, Shakira, and BTS as a co-headliner just weeks before the final, which explains why he sits atop the market leaderboard at a consensus 99.1% on Polymarket and Kalshi — reflecting near-certain confirmation. BTS (98.5% Polymarket, 99.0% Kalshi) and Coldplay (96.4% Polymarket, 99.0% Kalshi) show the widest notable cross-platform spreads, at 0.5 and 2.6 percentage points respectively, likely reflecting residual uncertainty over exactly how Coldplay participates, given that the production was curated by Coldplay's Chris Martin rather than the full band headlining outright. Swae Lee leads all unconfirmed acts at 36.0% on Kalshi, followed by Sabrina Carpenter (23.0%), Post Malone and KAROL G (both ~20%), suggesting some bettors anticipate surprise additions. Bieber's addition came just weeks before the final, giving organizers precedent for late additions to the lineup. Across both Polymarket and Kalshi, confirmed performers are priced near certainty while unconfirmed names carry meaningful spreads — a rare case where the two platforms broadly agree on the confirmed acts but diverge on the fringe contenders.
