Caltech hosts first research-level math hackathon with $2M+ AI credits

Caltech Mathathon – first hackathon ever devoted to research level mathematics

Caltech is running a 40-hour math hackathon on Oct 30 where 100 teams use frontier models from Anthropic and OpenAI to solve open conjectures, then defend results before mathematicians. Over $2M in AI credits is provided. Prizes come in two rounds: first for promising results, second after community verification. The post doesn't disclose prize amounts or eligibility criteria.

Why it matters: Novel format (first research-level math hackathon) backed by concrete AI-math breakthroughs and a sponsor list spanning DARPA to YC. Score held below 85 because the post is an event announcement — it doesn't detail judging criteria, model usage rules, or how the conjecture poo...

This caught my eye because it turns "AI doing math" from preprint headlines into a spectator event. The organizers cite three recent results as proof of momentum: OpenAI's model disproved the 80-year-old Erdős unit-distance conjecture, constructed the first explicit non-sofic group, and a third paper claims the six-sphere admits a complex structure (still unverified). Their framing question is blunt: how fast can AI compress the ideation-to-publication pipeline, and what's left for the mathematician?

The format is the interesting part. Teams defend results in front of mathematicians who judge understanding, not just output. Prizes come in two rounds, with the second gated on community verification—peer review baked into the competition structure.

What's missing: no prize amounts, no eligibility criteria, no word on how the 100 teams are selected. The sponsor list is a who's-who from DARPA expMath to a16z and YC, which reads more like ecosystem positioning than pure academic exercise. I'd treat this as a signal that frontier-model output in pure math is shifting from "surprising one-offs" to something people are trying to organize at scale.
