The Arc · recap

The Arc: the 2026 U.S. Open

On Thursday morning, before a single shot, we published a win-probability on every player in the field. By Sunday night, some of those numbers looked prophetic and some looked foolish. This is the honest scorecard — the winner’s arc, the round that broke our expectations, and the places the board got humbled.

We do this because it’s the one thing no golf outlet does: we commit a calibrated probability before the event, then show you, after, exactly where we were right and where we were wrong. The pre-tournament board is the win-probability we publish; the live Sunday swing below is liveslip’s own in-play engine, replaying every shot of the final round. Wyndham Clark won the 2026 U.S. Open at four under, by a single stroke over Sam Burns — but the story is in how the probabilities moved to get there.

Act I — what the board said Thursday

Coming in, the favorites on our board were Scottie Scheffler (12.3% to win), Rory McIlroy (6.7% to win), Jon Rahm (5.1% to win). The eventual champion, Wyndham Clark, sat at 1.2% to win (6.7% for a top-5) — a genuine longshot on our board, not a quiet favorite.

Act II — the tournament arc

Seventy-two players survived to the weekend. The story of the week belonged to the final round, where our live win-probability did something it rarely does for a 54-hole leader: it cracked, then healed. Sam Burns made the loudest charge of anyone else on Sunday — but our live model never turned the leaderboard over to him, and the lead held.

Act III — the champion’s arc

Clark carried the lead into Sunday, and our live model opened him around 72%. Then he gave shots back early, and the number sank to 53.4% — for a stretch, a coin-flip rather than a coronation. He steadied, the rest of the field never landed the knockout, and our line climbed all the way back — peaking at 97.2% through 16 — before he closed out a one-stroke win at four under, our last reading at 96.3%. A leader who survived the scare — the rare arc that dips through the danger and comes out the other side.

Act IV — where the board got humbled

This is the part most outlets skip. We don’t.

• Jon Rahm — the third favorite on our board at 5.1% to win (18.9% for a top-5). Missed the cut. The single biggest gap between what the board expected and what happened.
• Rory McIlroy — our second favorite at 6.7%, never contended and finished T32.
• Bryson DeChambeau — a 2.1% outright on our board, also missed the weekend.
• Where the board held up: our top overall favorite, Scottie Scheffler (12.3%), finished T4 — in the mix to the end, just not the winner.

Every one of these is a model estimate measured against what happened — not betting advice, and not a guarantee of anything. It’s a calibration check we publish in public, every tournament.

What’s next

That’s the arc. We earned some and gave some back — and you saw the receipts either way. Next up: The Read: the Travelers Championship, where we’ll publish our win-probability favorites before the first tee, so we can do this all over again next Sunday.
