When did the 2026-27 La Liga season start?

Saturday 15 August 2026, with Alavés v Getafe. Barcelona, Real Madrid and Atlético Madrid were given extra recovery time after the World Cup, so Atlético opened on 19 August, Real Madrid play Real Sociedad on 26 August and Barcelona face Athletic Club on 27 August.

Who is favourite to win La Liga in 2026-27?

Barcelona, chasing a third straight title after winning 2025-26 with 94 points. Mid-August prices put Barcelona at 8/11, around 58% implied, Real Madrid at 6/5, around 45%, and Atlético Madrid a distant third at 14/1.

Which World Cup 2026 players are in La Liga?

Most of Spain's World Cup-winning squad: Lamine Yamal, Pau Cubarsí, Pedri, Dani Olmo and Ferran Torres at Barcelona. Kylian Mbappé, the tournament's Golden Boot winner, and Vinícius Júnior play for Real Madrid, and Julián Álvarez is at Atlético Madrid.

Which La Liga prediction markets are most popular?

Season champion, Pichichi top scorer, top four and relegation, and per-match results. The champion market is efficient because two clubs hold almost all the probability; the top-four and top-scorer contracts carry the widest disagreement between platforms.

Is trading La Liga contracts legal in the US?

Yes. La Liga event contracts on Kalshi and Polymarket are federally regulated derivatives rather than state-licensed sportsbook wagers, so they are available in all 50 states to traders aged 21 and over.
