2026 U.S. Open — Wyndham Clark wins

The 2026 U.S. Open—Wyndham Clark wins a second title at Shinnecock

Wyndham Clark won the 2026 U.S. Open at Shinnecock Hills Golf Club, closing at 4-under to finish one clear of Sam Burns. Clark led wire-to-wire—carrying a six-stroke cushion into Sunday and grinding out par after par to hold off the charge—becoming the 24th multiple U.S. Open champion, adding to his 2023 title at Los Angeles Country Club. The USGA's $22.5M purse paid him $4.5M.

This workspace is the cross-exchange record of how the books priced the major. Kalshi's full-field winner Categorical (KXPGATOUR-USO26) and Polymarket's outright winner book (2026-us-open-winner) both resolved Clark; the pies below preserve the final implied distribution each exchange carried into Sunday, alongside the Round 1 leader Categorical and the season-long majors context.

Winner: Wyndham Clark (−4), by one over Sam Burns.
Venue: Shinnecock Hills Golf Club, Southampton, NY—its sixth U.S. Open.
Settled: June 21, 2026.

Kalshi's KXPGATOUR-USO26 was the deepest U.S. Open winner book this year; the pie shows the full field with no count cap, so the long tail behind Clark stays visible. Polymarket's outright winner Categorical sits beside it for the cross-exchange read—both resolved Wyndham Clark Yes.

The Round 1 leader Categorical settled after Thursday's round—it was the cleanest first-mover tell, repricing on every morning low score and converging as the afternoon wave finished.

Season-long context: who's banking PGA majors in 2026 (Multiple, settles December 31)—still live with the U.S. Open now in the books and the Open Championship to come—alongside the now-settled U.S. Open field Multiple.

• Cross-exchange spread on the winner. Kalshi and Polymarket both ran deep winner books into Sunday; the spread between them on the eventual champion is the cleanest read on which exchange priced Clark's wire-to-wire lead faster.
• Wire-to-wire convergence. The history chart shows the outright book tightening onto Clark from Thursday's lead through the six-shot Sunday cushion—a rare front-runner hold at a U.S. Open.
• PGA majors-in-2026 Multiple, still live. Kalshi's KXPGAMAJORWIN-26 tracks every player's major-win count across all four 2026 majors and settles December 31; the U.S. Open result now feeds it, with the Open Championship still ahead.
• Scheffler's majors-count Cumulative. Kalshi prices Scottie Scheffler's full-year major count as a Cumulative—the distinctive chart form stays in the stack as the season's remaining majors play out.
