Lamine Yamal's hamstring injury has sent ripples through the World Cup betting markets, with Spain losing their sole frontrunner status heading into the summer's most anticipated tournament.

Yamal, the teenage Barcelona star, has been ruled out for the remainder of the club season after tearing his hamstring. While reports suggest the injury will not cost him his place at the World Cup, the markets have reacted swiftly. Spain drifted from +450 — where they stood as the outright favourite — to +500, and France, previously priced at +550, have moved up to match them as co-favourites.

Spain's group dominance still commanding attention

Despite the Yamal news, Spain retain enormous support from bettors. A week before the injury was confirmed, BetMGM reported that Spain held a remarkable 92.5 percent of the handle to win Group H. As of Wednesday morning at theScore Bet, La Roja still attracted 18.2 percent of all World Cup winner wagers and 19.9 percent of the handle — both market-leading figures.

Spain's odds to win Group H edged slightly in the wrong direction for punters backing them, shifting from -500 to -450, while Uruguay's chances shortened from +400 to +370, though their overall World Cup title odds remained unchanged.

Broader market movements since the draw

Since the full tournament field was confirmed — but before the Yamal injury — a number of nations have seen their fortunes shift. Brazil improved from +850 to +800, while Morocco moved from 60-1 to 50-1, Croatia tightened from 90-1 to 80-1, and Switzerland followed a similar path from 100-1 to 80-1.

On the other side of the ledger, Norway drifted from 28-1 to 30-1, Mexico from 70-1 to 75-1, Ecuador from 80-1 to 90-1, and late-qualifier Turkey moved out significantly — from 65-1 to 100-1.

USA benefit from home-crowd sentiment

The host nation, the United States, saw their odds tighten from 65-1 to 60-1, a movement bookmakers attribute largely to outsized domestic betting interest rather than form. DraftKings Sportsbook director Johnny Avello captured the sentiment plainly.

American bettors will bet the U.S. every time they play.

Bookmakers across the market anticipate heavy patriotic backing for the Stars and Stripes throughout the summer, which is expected to continue shaping the odds as the tournament draws closer.
