SAINT LOUIS, October 26, 2026--The U.S. Chess Championships delivered a wild ride from start to finish, with high drama, hard-fought battles and championship dreams on the line in both divisions. In the Open, Grandmaster (GM) Fabiano Caruana and GM Wesley So battled their way into a playoff to decide the title, with So ultimately emerging as champion and taking home $56,000 – marking So's fourth title. The U.S. Women's Championship was equally action-packed, as 16-year-old rookie Woman International Master (WIM) Rachael Li of Plano, Texas, made a spectacular debut, claiming her first U.S. Women's Championship title and $45,000 in prize money.

"This year's championships showcased the incredible strength and depth of American chess," said Rex Sinquefield, co-founder of the Saint Louis Chess Club. "From Wesley So's championship run to Rachael Li's standout breakthrough, these events demonstrated the determination, talent and unpredictability that make chess so compelling. We are proud to bring the nation's top players to Saint Louis and give fans the opportunity to experience these extraordinary moments."

Wesley So Wins U.S. Chess Championship After Unforgettable Tournament

GM Wesley So of Excelsior, Minnesota, emerged as the 2026 U.S. Chess Champion after a tournament filled with unexpected twists and remarkable individual performances. So's victory capped a championship in which even the tournament's highest-ranked players faced formidable challenges from across the field.

The Open section produced two particularly striking upsets. In Round 5, bottom-seeded GM Andy Woodward defeated top-seeded GM Fabiano Caruana, ending Caruana's 54-game unbeaten streak. Woodward went on to finish fifth outright, delivering one of the tournament's strongest performances.

In Round 11, GM Sam Sevian, who entered the game in last place, defeated So, who was leading the standings at the time. The victory ended So's 48-game unbeaten streak and was Sevian's only win of the championship.

Despite the setback, So won a Rapid Chess playoff and finished the tournament as champion. Caruana placed second, while GMs Jeffery Xiong and Grigoriy Oparin tied for third. Woodward's fifth-place finish further underscored the depth and unpredictability of the field.
