AI for mathematics and theoretical physics Tomorrow's problems on yesterday's machines Axiom - École nationale des ponts et chaussées
Axiom launched six months ago with one conviction: mathematics is the right foundation for building systems that reason. Today we announce Axiom's Series A. We raised $200M at a $1.6B+ valuation, led by @MenloVentures, to extend our lead in formal mathematics into Verified AI.
1/ AxiomProver has solved Fel’s open conjecture on syzygies of numerical semigroups, autonomously generating a formal proof in Lean with zero human guidance. This is the first time an AI system has settled an unsolved research problem in theory-building math and self verifies.
1/ We’re proud to announce the Aarhus Math&AI Workshop, sponsored and co-organized by Axiom. Speakers include Fields Medalists Terence Tao and Maryna Viazovska✨ From Axiom: Francois Charton @f_charton, Alberto Alfarano @albe_alfa, Seewoo Lee @antimath3 See you in Denmark! ❄️
1/ AxiomProver got 12/12 of Putnam 2025. Today we release the Lean proofs AxiomProver generated autonomously. We also provide our take of the problems, proof visualizations, and compare how humans vs AI approach differently. Tons of fun math and Lean! Our findings in thread.
1/ The Collatz conjecture has humbled mathematicians for near 90 years. Paul Erdös said "mathematics is not yet ready for such problems." 🧵 So we handed it to transformers. What they learned stunned us! New research from Axiom's math discovery team, blog live this morning.
Axiom's new research blog: axiommath.ai/territory/lear… Learning Collatz - The Mother of all Rabbit Holes What happens when you train a transformer on one of math's most infamous unsolved puzzles -- and then study how it fails?
9/ Axiom's discovery team @f_charton @albe_alfa @KenOno691 is currently looking for a highly selected group of PhD interns. We are searching for candidates with advanced mathematics and strong machine learning backgrounds. Apply: axiommath.ai/join-us 📧 careers@axiommath.ai

Putnam, the world's hardest undergrad math contest, ended 4pm PT yesterday. By 3:58pm, AxiomProver @axiommathai autonomously solved 8/12 of Putnam2025 in Lean, a 100% verifiable language. Last year, our score would've been #4 of ~4000 and a Putnam Fellow (top 10 in recent yrs)
AxiomProver keeps getting stronger. And @axiommathai keeps growing. I'm excited to share that Prof. Ken Ono @KenOno691 has joined Axiom as Founding Mathematician and FTE #15. He left his tenured position as STEM Advisor to Provost at UVA to build an AI mathematician with us. Here's Ken's story. (1)

Introducing Axiom's discovery team: @albe_alfa Alberto's path runs from the IMO → trading → training AI to crack a 130-year-old conjecture. He found new Lyapunov functions while no general algorithm existed before. AI for math discovery redefines the boundary of human minds.
