At least 10 billion humanoid robots by 2040
“If you say like 2040, probably there are more humanoid robots than there are people. So on the order of 10 billion”
Elon Musk predicted well over a billion humanoid robots by Sep 1, 2036. It hasn't happened yet, with 3,602 days left.
Fetched Oct 17 2026: Wikipedia's Optimus page still has Generation 3 unrevealed (as of September 2026). Tesla has published no fleet anywhere near a billion humanoid robots. Deadline 2036-09-01. Status stays pending. Wikipedia — Optimus (robot), fetched Oct 17 2026: Gen 3 unrevealed; nowhere near a billion units ↗
On September 1 2026 at the G20 Innovation Ministerial in Chapel Hill, Elon Musk said that 10 years from now there would be well over a billion humanoid robots, and that he would put serious money on at least a billion robots in 10 years each producing at least five times the output of a human — more productive than all humans combined.
“If you say like 2040, probably there are more humanoid robots than there are people. So on the order of 10 billion”
“That there will be in 5 years, let's say at least 100 million humanoid robots, but maybe a billion.”
What happened: Fetched Oct 21 2026: Electrek Sep 25 reports Tesla ramped Optimus to several hundred/week in August, targeting 1,000/week by year-end — still internal test/training units, not a global installed base of 100 million humanoid robots. Deadline 2031-05-19. Status stays pending. Electrek Sep 25 2026 (fetched Oct 21) — Optimus hundreds/week internal; nowhere near 100 million global units ↗
