World Cup 2026 Winner Odds — At a Glance

The 2026 FIFA World Cup runs June 11 to July 19 across the United States, Mexico, and Canada. With $321M+ already traded on the tournament winner contract across Kalshi and Polymarket, this is the largest single sports prediction market in history. For Florida residents, prediction markets are the only fully-legal way to take an outright winner position — Hard Rock Bet (Florida's only legal sportsbook) doesn't list World Cup futures with anywhere near the same liquidity or pricing.

Kalshi vs Polymarket: Which Has Better World Cup Pricing?

Both exchanges are CFTC-registered and legal for FL residents. The differences matter:

• •Kalshi — works on iOS, Android, web. Deeper liquidity on US-favorite teams (USA, Mexico, England). New users who trade $25 get $25 with code MIAPREDICTS.
• •Polymarket — iOS-only in the US (no Android, no desktop trading via app — web is read-only). Generally tighter spreads on European teams and Argentina because of larger international order book. Use code MIAPREDICTS for a $50 trading bonus.

The arbitrage tell: when Kalshi and Polymarket disagree by 2+ cents on a major contract, the European-fund-heavy Polymarket is usually closer to true. The Kalshi premium on US-friendly teams is a real, recurring pattern.

• •Top scorer (Golden Boot) — Mbappé, Haaland, Vinícius Jr. lead.
