Why do almost all Fields Medalists hold mathematics PhDs?

The Fields Medal is widely considered one of the highest honors in mathematics, traditionally awarded to researchers holding doctorates in mathematics. However, the prize's history includes rare exceptions. Notably, out of dozens of recipients, exactly two individuals have received the medal despite holding PhDs in physics rather than mathematics.

What we know

• The Fields Medal is awarded every four years to two, three, or four mathematicians under 40 years of age. [1, 2]
• With the exception of two PhD holders in physics, Edward Witten and Martin Hairer, only people with a PhD in mathematics have won the medal. [2]
• A total of 68 people have been awarded the Fields Medal as of 2026. [2]
