TL;DR:

Recap: The USA's run ended in the Round of 16 with a 4-1 loss to Belgium in Seattle on July 6; Malik Tillman scored the US goal. Spain won the tournament. The USMNT trades 3-5% YES to win the 2026 World Cup outright on Kalshi and Polymarket. Above sharp model consensus (1.8-2.5%) because US retail flow keeps a structural 3-5 point premium. Reach round of 16: 55-65% YES. Reach quarterfinals: 22-32%. Reach semifinals: 8-14%. Reach final: 3-6%. The cleanest trade is 'reach quarterfinals YES at 22-28%', direct hosting-advantage expression without paying the championship-tail premium. Kalshi has the deepest USMNT book for round-by-round and match contracts (US retail concentrates there); Polymarket has tighter pricing relative to model consensus. In-game pattern: USA contracts gap up 4-8 points in the first 20 minutes on Kalshi; if the US hasn't scored by the 30th minute, the contract over-extends and is a clean fade. CFTC-regulated and available to eligible California residents (dispute pending).

The USMNT is the highest-volume retail contract on US prediction markets for the entire 2026 World Cup. Home flow keeps the US 3-5 points above sharp model consensus across every round, which makes the knockout-stage USMNT contracts both the most-traded and the most consistently mispriced on the board. Here's where the US sits on Kalshi (opens in a new tab) and Polymarket (opens in a new tab), where the home-flow premium lives, and the cleanest knockout trades for California fans.

TL;DR:

The USMNT trades around 1.5% to win the 2026 World Cup but is the highest-volume retail contract on Kalshi and Polymarket all tournament. Home-crowd flow runs the US 3-5 points above sharp model consensus across every knockout round, making the round-of-16 and quarter-final contracts the most consistently mispriced on the board.

What are the USMNT's 2026 World Cup knockout odds?

The USMNT trades 3-5% YES to win the 2026 World Cup outright on Kalshi and Polymarket. Sharp model consensus (Opta SuperComputer, FiveThirtyEight-style frameworks) puts the US at 1.8-2.5%, so the home-flow premium is structural and persistent. Where the market is more honest:

StageOdds
USA reaches round of 1655-65% YES, broadly in line with model consensus.
USA reaches quarterfinals22-32% YES; 2-4 point home premium.
USA reaches semifinals8-14% YES; 3-5 point home premium.
USA reaches final3-6% YES; 2-3 point home premium.

When are the USMNT's knockout matches?

If the USMNT advances from Group D, the round of 32 runs June 28: July 2, round of 16 July 4-7, quarterfinals July 9-11, semifinals July 14-15, final July 19 at MetLife Stadium. The US has confirmed host-nation positioning in the upper half of the bracket, with most projected US knockout matches landing on the East Coast (Philadelphia, MetLife, Atlanta, Dallas). California traders watching from PT see typical kickoffs at 12pm and 3pm PT.

What USMNT knockout contracts are tradable?

Five contract families on Kalshi and Polymarket:

  1. USA wins World Cup outright: 3-5% YES. Deepest US flow of any single contract on the entire tournament board.
  2. USA round-by-round survival contracts: reach round of 16, quarters, semis, final. The cleanest expression of a structured view.
  3. Individual match contracts: listed 24-48 hours before each knockout fixture. Tightest spreads of any USA contract.
  4. USA vs Mexico knockout: conditional bracket contract; 8-12% YES that the two CONCACAF nations meet in the round of 16 or quarterfinals.
  5. Christian Pulisic / Folarin Balogun top-USA-scorer: player props on Polymarket and Fanatics Markets.

First-hand note

"The single most consistent fade I've watched in three tournament cycles: USA contracts gap up 4-8 points in the first 20 minutes of every USMNT knockout match on Kalshi as US retail flow piles in. If the US hasn't scored by the 30th minute, the contract over-extends and is a clean fade against Polymarket where global flow doesn't have the same emotional pressure. The trade isn't a championship view. It's a flow-arbitrage view."

: Catie Di Stefano, Editor-in-Chief · June 16, 2026

USMNT contracts trade 3-5 points richer on Kalshi than Polymarket: not because of skill divergence between the books, but because US retail flow doesn't fully arbitrage out across borders.

Three trades with the best risk/reward profile:

  1. USA reach quarterfinals YES at 22-28%: direct expression of a host-advantage view without paying the championship-tail premium. The historical hosting bump is +8 to +12 points on round-of-16 win probability; pre-bracket pricing typically under-weights this.
  2. Fade USA outright YES at 4-5% on Kalshi: buy the identical contract 1-2 points cheaper on Polymarket, or skip the lottery ticket entirely.
  3. USA vs Mexico knockout conditional: the cleanest narrative trade on the board if both teams advance from groups. Covered in depth in our USA vs Mexico World Cup hub.

How does host-nation advantage actually move the price?

Hosting historically swings round-of-16 win probability by +8 to +12 points for the host nation, based on every World Cup since 1990. The mechanics are well-understood: shorter travel, no jet lag, friendly officiating dynamics in front of home crowds, and a 60-80% home-supporter share in stadium attendance. The market does price hosting advantage. But inconsistently, with the largest mispricings showing up in the round-of-16 'reach quarterfinals' contract where retail under-weights structural advantages relative to roster-based form.

Available, dispute pending (as of October 13, 2026). California residents 21+ can trade these contracts on CFTC (opens in a new tab)-regulated exchanges while the courts decide how far state gambling law reaches. California has no legal online sportsbook. These are the only legal venues for real-money USMNT trading in the state. Full picture in our California prediction markets guide and the World Cup 2026 California legal guide.

Where's the deepest USMNT book. Kalshi or Polymarket?

Kalshi has the deepest USMNT-specific book for round-by-round and match contracts because US retail flow concentrates there. Polymarket has tighter pricing relative to model consensus because global flow keeps the US contract closer to fair value. For California traders the best setup is Kalshi for a downloadable profit-and-loss statement and match-flow liquidity, Polymarket for cleaner pricing on outright and 'reach final' contracts. See our Kalshi vs Polymarket fees comparison for the full cost side.

How do I deposit to trade USMNT contracts?

Kalshi accepts ACH, debit card and bank wire, with same-day funding for deposits under $10,000. Polymarket US is funded in US dollars inside its app; see how to deposit on Polymarket from California for the steps. New users who deposit $10 with code CAPREDICTS get a $25 trading bonus.

What's the in-game USMNT playbook?

Four concrete moves for any USA knockout match:

Game MomentPlaybook Action
Pre-game (T-2 hours)Cross-platform check. If Kalshi USA YES is more than 4¢ above Polymarket, fade Kalshi, buy Polymarket.
First 20 minutesWatch for the home-flow gap-up on Kalshi. If the US hasn't scored, the contract typically over-extends.
30th minute scorelessFade window. The over-extension corrects over the next 15 minutes.
Late game with USA aheadBuy 'reach next round' contracts; they often lag the in-game probability by 4-6 points until the final whistle.

How does this fit with the broader USA-Mexico hub?

Frequently asked questions

What are the USMNT's 2026 World Cup odds?

The USMNT trades 3-5% YES to win the World Cup outright on Kalshi and Polymarket. Sharp model consensus puts the US at 1.8-2.5%, so the home-flow premium is structural. Reach round of 16: 55-65% YES. Reach quarterfinals: 22-32%. Reach semifinals: 8-14%.

When are the USMNT's knockout matches?

If the USMNT advances from Group D: round of 32 runs June 28: July 2, round of 16 July 4-7, quarterfinals July 9-11, semifinals July 14-15, final July 19 at MetLife Stadium. The US has confirmed host-nation positioning in the upper bracket half, with most projected knockout matches on the East Coast.

What USMNT knockout contracts are tradable?

Five families. USA wins World Cup outright (3-5% YES, deepest US flow on the board). USA round-by-round survival. Individual match contracts (24-48 hours before each fixture, tightest spreads). USA vs Mexico knockout conditional (8-12% YES). Pulisic/Balogun top-USA-scorer player props on Polymarket and Fanatics Markets.

Where's the cleanest USMNT knockout trade?

Three. USA reach quarterfinals YES at 22-28%, direct host-advantage expression without championship-tail premium. Fade USA outright YES at 4-5% on Kalshi against the same contract 1-2 points cheaper on Polymarket. USA vs Mexico knockout conditional. Cleanest narrative trade if both teams advance from groups.

How does host-nation advantage move the price?

Hosting historically swings round-of-16 win probability by +8 to +12 points based on every World Cup since 1990. Shorter travel, no jet lag, friendly officiating dynamics, 60-80% home-supporter stadium share. The market prices hosting inconsistently. Largest mispricings show up in the 'reach quarterfinals' contract where retail under-weights structural advantages relative to roster-based form.

Where's the deepest USMNT book. Kalshi or Polymarket?

Kalshi has the deepest USMNT-specific book for round-by-round and match contracts because US retail flow concentrates there. Polymarket has tighter pricing relative to model consensus because global flow keeps the contract closer to fair value. California traders typically use Kalshi for a downloadable profit-and-loss statement and match-flow liquidity, Polymarket for cleaner pricing on outright and reach-final contracts.

Is USMNT trading legal in California?

Available, dispute pending (as of October 13, 2026). Kalshi and Polymarket accept California residents (minimum age 18; we recommend 21+) and list these contracts on CFTC-regulated exchanges. Whether states can apply their gambling laws to sports contracts is still being decided: in August 2026 the 9th Circuit, whose rulings cover California, ruled at the preliminary stage that Kalshi is unlikely to show federal law overrides Nevada's gaming law, and three petitions to the Supreme Court are pending (Nos. 26-299, 26-338 and 26-344; none granted). California has not brought its own case against the platforms.

Does California law prohibit trading on USMNT match outcomes?

No. California residents (minimum age 18; we recommend 21+) can legally trade USMNT contracts on CFTC-regulated platforms such as Kalshi and the Polymarket US app. Propositions 26 and 27 failed to legalize online sportsbooks in California, but prediction markets operate under federal event-contract rules rather than state sports betting law.

Are USMNT knockout contracts settled based on 90 minutes or the final result?

Settlement depends on the specific contract rules. 'To Advance' contracts settle based on which team reaches the next round, including extra time and penalties. 'Match Result' contracts typically settle based on the score at the end of 90 minutes plus stoppage time. Users should check the individual contract rules on Polymarket or Kalshi before trading.
