Four teams left, and the market is reading both games backwards. France meet Spain at AT&T Stadium on Tuesday in a rematch of the Euro 2024 semifinal, and Kalshi has moved France to a clear favorite the model simply doesn't see. Then England and Argentina renew one of the sport's oldest grudges in Atlanta on Wednesday, both dragging 120 minutes of quarterfinal football in their legs. Two games, two price gaps, one Play of the Day.
France vs. Spain (AT&T Stadium, Dallas — Tuesday, July 14, 3:00 PM ET)
The mispriced semifinal. The 90-minute market on Kalshi trades France at 43¢, the draw at 30¢ and Spain at 30¢. The model's 10,000-run read on the same three outcomes: Spain 37.1%, draw 30.0%, France 32.9%. The draw is priced perfectly. The two sides are swapped. That makes Spain to win in regulation at 30¢ a seven-point value gap — the widest on the card — and France at 43¢ a ten-point premium you should be selling, not buying.
Where did the gap come from? Recency. France's quarterfinal was the controlled 2-0 over Morocco in Boston — never stressed, never chasing. Spain needed Mikel Merino's 88th-minute header to put away Belgium 2-1 at SoFi after Charles De Ketelaere had equalized. One win looked routine and one looked like an escape, and the market repriced the semifinal off the look. The simulation doesn't watch highlights: head-to-head it gives Spain the slight edge, 1.41 to 1.32 expected goals, in a 2.72-total game. It's also worth saying out loud that Spain won the last meeting that mattered — the Euro 2024 semifinal, 2-1, the night Lamine Yamal announced himself — and this Spain side still builds through Yamal, Pedri's control and Fabián Ruiz's arrival from deep.
The totals are the pass here. Over 2.5 trades at 52¢ against a 51.2% model read — no edge either way — and both-teams-to-score at 61¢ is actually rich against the sim's 57.4%. The scoreline board is stacked tight: 1-1 (14.4%), 0-0 (8.8%), 1-2 Spain (8.6%), 2-1 France (8.0%). This is a coin-flip with a Spain tilt, and the only number worth owning is the cheap side of the flip. If you'd rather hold the extra-time and penalty paths too, Spain to advance trades at 41¢ — but the regulation contract at 30¢ is where the model's edge is concentrated.
England vs. Argentina (Mercedes-Benz Stadium, Atlanta — Wednesday, July 15, 3:00 PM ET)
The rivalry, and the second value side. First World Cup meeting since 2002, in a series that gave the sport the Hand of God, the Goal of the Century and Beckham's red card. Both semifinalists earned this the hard way, on the same Saturday, in the same fashion: 1-1 after 90 minutes, then extra time. England beat Norway 2-1 on a Jude Bellingham double — the winner three minutes into extra time — and Argentina put away ten-man Switzerland 3-1, Julián Álvarez and Lautaro Martínez striking in the 112th and 121st minutes after Breel Embolo's 72nd-minute red card finally told. Equal rest, equal miles, no fatigue asymmetry to price.
The market makes England the favorite: 37¢ to win in 90, the draw at 33¢, Argentina at 32¢. The model flips it — Argentina ~37%, England ~33%, the draw 30% — off the defending champions' higher overall rating and tournament-hardened knockout profile. That's a five-point gap on Argentina in regulation at 32¢, and it comes with the same recency warning as Dallas: Bellingham's heroics were the last thing the market watched, and Argentina winning ugly in extra time is exactly how Scaloni's side has always traded — undervalued in regulation because they refuse to win pretty. The sim refreshes nightly against live data, so check the matchup page before kickoff for the current line.
The supporting lean is under 2.5 goals. Over 2.5 trades at just 42¢ — the market already knows what this is — and the profile agrees: Tuchel's England are built on structure, Scaloni's Argentina grind tournament knockouts (three of their last four went past regulation), and both quarterfinals sat at two goals through 90 minutes. Both-teams-to-score at 52¢ is the coin-flip version of the same question and worth a pass. If you want a scorer expression instead, Harry Kane against a 120-minute-old Argentine back line is the cleaner route than chasing Messi's price into England's control — check both on the matchup page against each side's team total.
Play of the day: Spain to win in regulation (30¢ on Kalshi, model 37.1%). The widest model-market gap of the semifinal round, on the side the simulation actually favors. The contract already pays you to carry the extra-time risk — a 30¢ price on a 37% outcome is the definition of taking the good side of variance — and the fallback expressions are all priced fairly or rich, so this is where the whole edge lives. The value stack is Argentina in regulation at 32¢ on Wednesday, the same trade in a different shirt: the model's favorite selling at an underdog price. Both value sides in regulation form a natural two-leg on the Combo Edge Builder — separate settlements, correlated as a fade-the-recency card, so price the stack before you build it. Size everything quarter-Kelly, and sanity-check any price move against the EV calculator before entry.
One housekeeping note, because we grade everything: the quarterfinal card split. France in regulation at 62¢ and the Spain–Belgium over at 52¢ both cashed; Saturday's two regulation favorites both needed extra time, so England-in-regulation at 52¢ graded a loss even though England advanced. That's the deal with regulation contracts — the discount you're paid up front is the extra-time risk. The full graded ledger is on the track record page.
