When is the 2026 World Cup round of 16?

July 4–7, 2026. Eight matches across four days, with the winners advancing to quarterfinals July 9–11. This is the first round of 16 to follow a 32-team knockout round — the surviving 16 teams in 2026 have already played one extra knockout game compared to every previous World Cup.

What round-of-16 contracts can I trade?

Three families on Kalshi and Polymarket. 'Reach round of 16' survival contracts (resolve when group position locks). 'Reach quarterfinals' contracts (cleanest curse-breaker plays for Mexico, USA, Japan). Individual match contracts that list 24–48 hours after the bracket locks with the tightest spreads of the tournament.

Which round-of-16 contracts have the most edge?

'Reach quarterfinals' on teams with historic round-of-16 ceilings. Mexico has lost in the round of 16 in every World Cup since 1994 (seven straight); the 'breaks the curse' contract typically trades 4–7 points below model fair value because retail flow remembers the pattern. USA, Japan, and Switzerland show similar discounts.

What odds should I expect for the favorites?

Top-5 contender vs group runner-up: 70–82% YES. Top-5 contender vs another top-10 nation: 55–65% YES. Mid-tier vs mid-tier: 45–55% YES (tightest spreads). Host nations (USA/Mexico/Canada) carry a 4–8 point home-flow premium.

How does the round of 16 reprice outright winner contracts?

It's the second-largest repricing event of the tournament after group stage end. Each upset redistributes 3–6¢ of championship probability across surviving top-fives. Two favorites eliminated on the same day pushes the next-tier (Portugal, Germany, Netherlands) up 4–8¢ on outrights.

Is round-of-16 trading legal in California?

Yes. Round-of-16 match contracts and 'reach quarterfinals' contracts on Kalshi and Polymarket are CFTC-regulated and available to California residents 21+ under federal commodities law, which preempts state sportsbook prohibitions.
