Stanford alumnus Peter Chatain surged from fourth place to gold in the men's four at the 2026 World Rowing Championships in Amsterdam on Sunday, Aug. 30.

Chatain and his U.S. teammates clocked 5:41.57, edging the host Netherlands by 0.27 seconds in a finish decided in the closing meters. It was Chatain's first senior World Championship title. He earned a bronze medal in the men's eight at the 2024 Paris Olympics.

The U.S. boat sat fourth through the opening 500 meters before working through the field, according to Stanford Athletics. Chatain rowed the two-seat alongside Gus Rodriguez, Christopher Carlson and Pieter Quinton. The Netherlands finished in 5:41.84, and Great Britain took bronze in 5:44.16.

Chatain also picked up a bronze medal in the mixed eight, where the U.S. finished in 5:38.61 behind gold-medalist Romania (5:35.75) and the Netherlands (5:38.42). The silver medal in that race was decided by 0.19 seconds.

Fellow Stanford alumna Azja Czajkowski rowed on the U.S. women's four, which also won gold. That made history. Stanford Athletics said it was the first time the U.S. men's and women's fours both topped the podium at the same World Championships.

Chatain majored in mathematics at Stanford and was named Pac-12 Rowing Athlete of the Year in 2021. He also earned a master's degree in computer science from the university. After graduating, he joined the Oakland-based California Rowing Club, where he trains under coach Mike Teti.

In an August 2024 interview with the Chicago Tribune during the Paris Olympics, Chatain described the discipline behind balancing elite rowing with his career as a machine learning engineer. "If you have a bad day rowing or the boat's not going well, it's going to weigh down your entire mood if it's the only thing you're thinking about," he said. "You have to have things to get your mind off it."

Two other Stanford alumni competed at the championships. James Wright finished sixth in the men's quadruple sculls, and James Fetter placed 19th in the double sculls. The United States led the overall medal table with three golds and three bronzes.
