Elon Musk announced Tesla's ambitious goal to build 10,000 Optimus robots in 2025, though he anticipates producing only a few thousand units that will perform useful tasks. Tesla is also developing a production line capable of 10,000 units per month and plans to sell the robots to third parties next year, with a target price under $20,000 when production reaches 1 million units annually. Musk envisions the Optimus program becoming a significant revenue source for Tesla, despite acknowledging the challenges ahead.
