United States 4–1 Paraguay: how the Jarvis supercomputer's prediction held up

USA 4–1 Paraguay: a dream opening night for the hosts

SoFi Stadium witnessed a perfect night for the World Cup 2026 co-hosts. The United States went into their Group D opener against Paraguay in good form after a run of pre-tournament friendlies, where Christian Pulisic and Folarin Balogun repeatedly left their mark up front. The 4–1 scoreline reflected the run of play: the hosts took control early and never let their opponents settle.

Before kickoff, the Jarvis supercomputer model predicted USA with a 49.0% chance of winning, compared with 28.4% for a draw and just 22.5% for Paraguay. With a roaring home crowd behind them and key names such as centre-back Chris Richards back in the fold, Jarvis rated the hosts' winning chances as clearly superior, and the pitch confirmed it.

How it unfolded: a costly own goal, Balogun's brace and a 90+8 full stop

Paraguay were rated highly for their low-block defending and counterattacking, but it was their own back line that threw the door wide open. In the 9th minute, defender Juan Jose Caceres turned the ball into his own net, gifting the hosts the opening goal as the American crowd erupted. The early setback forced the South American side to push forward, and that was when the hosts' attack punished them.

Folarin Balogun became the standout name of the match. The number 20 striker made it 2–0 in the 31st minute, then completed his brace in the 45+5 minute, all but wrapping up the game right before the break. In the second half, Paraguay pulled one back through Mauricio in the 73rd minute, lighting a brief spark of hope.

But the hosts allowed no upset. In the 90+8 minute, Giovanni Reyna, who had not been in the starting eleven, scored to seal the 4–1 win and cap a joyous opening night exactly as the American fans had hoped.

Jarvis prediction review: right on the home win

Before the match, Jarvis put out three probabilities: USA to win 49.0%, a draw 28.4%, Paraguay to win 22.5%. The scenario given the highest rating was a home win, and the 4–1 result matched that read completely. That is a plus for the model in an opening game full of psychological variables.

What stands out is that Jarvis did not treat this as an absolute one-way contest: 22.5% for Paraguay and 28.4% for a draw showed the model still respected the South American side's ability to cause problems with tight defending and counterattacking threats like Julio Enciso. On the pitch, Paraguay did manage a goal, but the gap in quality and the 9th-minute mistake turned Jarvis's near-50% scenario into reality.

Starting lineups

USA starting eleven: goalkeeper Matt Freese (24); defenders Sergino Dest (2), Chris Richards (3), Antonee Robinson (5), Tim Ream (13), Alex Freeman (16); midfielders Tyler Adams (4), Weston McKennie (8), Malik Tillman (17); and the attacking pair of Christian Pulisic (10) and Folarin Balogun (20). Chris Richards's timely return let head coach Mauricio Pochettino run his three-centre-back defence exactly as intended.

For Paraguay: goalkeeper Orlando Gill (12); defenders Omar Alderete (3), Juan Jose Caceres (4), Junior Alonso (6), Gustavo Gomez (15); midfielders Diego Gomez (8), Miguel Almiron (10), Andres Cubas (14), Damian Bobadilla (16); together with the two forwards Antonio Sanabria (9) and Julio Enciso (19). This framework was built to defend tightly and lie in wait, but Caceres's early own goal wrecked the entire plan.

Conclusion: the hosts send a message, Jarvis scores on opening night

The 4–1 win was a firm statement from the United States on their home opening day: an attack sharpened by Balogun, Pulisic as the focal point, and squad depth deep enough that a substitute like Reyna could still get his name on the scoreboard. For Paraguay, Mauricio's goal was a rare comfort on a night when everything fell apart from the 9th minute onward.

As for the model, Jarvis began this World Cup with an accurate prediction: the highest-probability outcome (USA to win, 49.0%) was exactly the final result.
