Ultimate Fighting Bots · 2026
Ultimate Bots
Ultimate Fighting Bots, trading as Ultimate Bots, is the largest American humanoid fighting league and the one this site was missing.
It began in 2025 as invite-only fights in the basement of Frontier Tower on Market Street in San Francisco, the first in July, founded by Vitaly Bulatov, Xenia Bulatov and Michael Cho. Season 1 moved to Temple SF.
The machines are Unitree G1s and Booster T1s, driven with standard game controllers — and, unusually, from a browser, which means a pilot can compete from anywhere. Unitree became the league's official robotics partner in November 2025. In January 2026 UFB staged a humanoid bout inside the BattleBox at CES, in partnership with BattleBots.
Season 2 runs 1 October 2026 to 31 March 2027: four teams, a $100,000 prize pool, and a league-assigned Unitree G1 for every team, so nobody has to buy a robot to enter. Other partners include Nebius, Weights & Biases, MongoDB and Virgin Music Group.

How to enter
Create an account. Signing up IS the registration — there is no separate application. Pilots drive the humanoids in the arena; the league is explicitly recruiting gamers, athletes and performers rather than engineers.
Same signup, different role. A Ghost works the Physical AI stack behind the robot rather than driving it.
