2026 Fields Medals go to Hong Wang, Yu Deng, John Pardon and Jacob Tsimerman at ICM Philadelphia
At the opening of the International Congress of Mathematicians in Philadelphia on July 23, 2026, the IMU awarded the Fields Medals to Hong Wang, Yu Deng, John Pardon and Jacob Tsimerman. The awards are human results, but the congress was dominated by debate about AI in mathematics, and Tsimerman used his platform to talk about AI.
Key facts
- Hong Wang (NYU and IHES): co-authored the 2025 proof of the three-dimensional Kakeya conjecture; the third woman to win, after Mirzakhani (2014) and Viazovska (2022)
- Yu Deng (University of Chicago): rigorous derivation of fluid equations across scales (Boltzmann equation from hard-sphere dynamics)
- John Pardon (Stony Brook): symplectic geometry, virtual fundamental cycles, knot distortion (solved as a Princeton undergraduate)
- Jacob Tsimerman (University of Toronto): André–Oort conjecture, o-minimality in arithmetic and algebraic geometry
- Tsimerman on AI (Scientific American): 'One of the many scary things about AI is that we don't really understand the system very well'
- AI context: the next day Terence Tao gave the ICM public lecture 'Mathematics in the age of AI'. Tsimerman also took part in OpenAI's August 'future of mathematics' summit, per Daniel Litt's thread
What happened
The International Mathematical Union announced the four 2026 Fields Medallists at the start of ICM 2026 in Philadelphia (July 23–30).
Why it matters
This is context for the AI-and-mathematics story of 2026. The medals went for human work while AI systems were starting to settle open problems, and ICM discussions (Tao's lecture, and later the Fields Medallists' open letter of September) were largely about how mathematics should respond.
