The quarterfinals move to Los Angeles with the tournament's most complete team against the one that keeps scoring. SoFi Stadium gets Spain — unbeaten in the group and 2-0 through the knockouts, the market's standing favorite — against Belgium, a side that outlasted Senegal in extra time and then put four past the USA. One game on the July 10 card, and the model's read is a clean contrast to Thursday: Spain control it, but the goals come.
Spain vs. Belgium (SoFi Stadium, Los Angeles)
The favorite is right, and this time the total goes with it. The model has Spain at 59.2% to win in 90, the draw at 25.3% and Belgium at 15.5%, off a 1.93-to-0.92 expected-goals edge — the widest favorite number of any quarterfinal. That makes fair value on Spain in regulation right around 59¢: a play when the live Kalshi line trades under it, a pass when the market has already run past it. When the favorite is fairly priced, you look for the cleaner supporting expression — and here, unlike Thursday's under, it points up.
Over 2.5 goals is that expression. Spain project to 1.93 expected goals, Belgium to 0.92, for 2.84 total — a full third of a goal higher than the France-Morocco grind. The scoreline distribution runs hotter: the 1-1 draw (12.1%), 2-0 Spain (10.8%), 2-1 Spain (9.9%) and 1-0 Spain (9.4%) lead the board, over 1.5 is up at 79.4%, and over 2.5 prices at 54.1%. This is where Belgium reinforce the read rather than threaten it: the side that scored four on the USA and needed extra time to shake Senegal is not a deep, low-event block — they keep the ball moving and BTTS lives at 53.1%. Spain to win and over 2.5 is the side-and-total hybrid for anyone who wants a single script — the favorite controls the tie, but both attacks touch the scoreboard. Belgium's live out is the shootout: the draw pushes this to extra time and penalties, where they have already gone the distance once this tournament.
The scorer market is the last layer. Lamine Yamal drives the Spain attack as the tournament's chief creator, but it's Mikel Oyarzabal — four goals, two braces already — who's Spain's live Golden Boot outsider. Belgium's open, two-way shape is a different backdrop than a stingy block — the goals are there, so the scorer prices reflect it. Read the price on the matchup page against the model's team totals before you take it; the moneyline and the over are the higher-confidence numbers.
Play of the day: Spain to win in 90 minutes (fair value ~59¢). The model's cleanest number on the card — 59.2% in regulation on a 1.93-to-0.92 expected-goals edge — against a Belgium side the same model gives 15.5% to win outright. It's a play at a discount and a pass at a premium, so anchor to the live line: take Spain in regulation only where Kalshi is offering below ~59¢, and let the draw-and-shootout branch talk you out of overpaying. Prefer the total? Over 2.5 goals at ~54¢ fair is the supporting play, and the two stack naturally — Spain in regulation plus the over is a favorite-controls-a-goals-game card. Size it quarter-Kelly, and build the two-leg on the Combo Edge Builder so you're pricing the correlation, not ignoring it.
