Tesla CEO Elon Musk Elon asserts that the market for humanoid robots, like the Tesla Optimus Robot, will be 1 billion units per year, and Tesla can make $1 trillion a year selling them. He predicts that they will ultimately sell for around $20,000 at a cost of $10,000, and Tesla will capture at least a 10% market share of the humanoid robot market. Musk believes that there will be at least one robot per human, and perhaps even more than that.
