The International Mathematical Union (IMU) announced the 2026 Fields Medal winners at the opening ceremony of the International Congress of Mathematicians (ICM 2026) at the Pennsylvania Convention Center in Philadelphia on 23 July 2026 local time. The four laureates are Yu Deng of the University of Chicago, Hong Wang of New York University and France's IHES, John Pardon of Stony Brook University, and Jacob Tsimerman of the University of Toronto. Deng was recognised for work in partial differential equations and Wang for harmonic analysis and geometric measure theory — the first time Chinese-born mathematicians have won the award, and Wang is only the third woman ever to receive it. Often called the "Nobel Prize of mathematics," the Fields Medal is awarded once every four years to mathematicians under 40. The Abacus Medal went to Shayan Oveis Gharan of the University of Washington and the Chern Medal to Graeme Segal of Oxford.

Background & Context
There is no Nobel Prize for mathematics, which is why the Fields Medal is treated as the discipline's highest honour. Two features make it unusual. It is awarded only once every four years, at the International Congress of Mathematicians, so at most a handful of medals exist per cycle. And it carries an age limit of 40 — the intent is to recognise work that will shape the field going forward, not to crown a career. That is what the separate Chern Medal does, honouring lifetime achievement, while the Abacus Medal recognises mathematical contributions to computer science.
