Musk: It Takes “20 to 30 Million Robots” to Match America’s Output. That’s Optimus’ Market David Hanson Thu, November 12, 2026 at 5:19 PM EST 5 min read TSLA +2.30% Trade Tesla on Coinbase Trading disclosure Trading disclosure The above button links to Coinbase.

Elon Musk says about 20 to 30 million humanoid robots would match US output of goods and services, and Tesla's Optimus is chasing that market.
Tesla still has to win a share of that market and earn a margin on it, and analysts don't expect its normalized EPS to get far past fiscal 2023's level until fiscal 2028.
Tesla guides to about $20 billion of capex this year, more than its cash from operations in any of the last five years, and robots, robotaxis and chips all need that money.
At 183x forward earnings, investors are already paying for much of the robot future, and Tesla's 2027 capex guidance in late January is the next marker.
Tesla (TSLA:NASDAQ) is winding down Cybertruck production at Gigafactory Texas around mid-2027 to make room for more Cybercab output. Tesla has only so much factory space and cash, and it's already choosing where they go.
Optimus could need more of both than anything else Tesla makes, and Elon Musk just put a size on its market. In a fireside chat with Ron Baron at the Baron Investment Conference on Nov. 6, Musk put it this way:
"you'd need, you know, about 20 to 30 million robots to match the goods and services output of the United States"

Musk worked it out from the number of workers. About half of Americans are in school or retired, and not everyone of working age does productive work. That leaves him with perhaps 120 million people producing more than they use. He expects a robot to do at least five times a human's work, and 120 million divided by five is 24 million, right in the middle of his range.
On this week's episode of Moonshots with Peter Diamandis, co-host Dave Blundin said Musk is "a bit high," and that "10 million robots will do it because 45% of US jobs are manual jobs."
Either way, Tesla would need to build millions of robots every year. Musk says the high-volume Optimus line in Fremont will reach 1 million units a year, and in October he said it's at least a year from building 20,000 a week. At that pace, it would take that one line a decade to build even Blundin's 10 million.
Musk counted the robots it would take to do America's work. He didn't say how many would be Tesla's, or what Tesla would earn on each one. And Tesla won't have the field to itself: Figure AI is building humanoids too, and Blundin "wouldn't even be surprised" if OpenAI and Anthropic have their own robots within two to three years.
Analysts can only price the business Tesla has today, and they expect its normalized EPS to climb back slowly, to $3.24 in fiscal 2028, barely above fiscal 2023's $3.12:
I wouldn't expect a robot count to move those estimates, since Musk expects Optimus deliveries to outside companies to start around the end of 2027.
Tesla has paid for its factories out of cash from operations, which has run between $11.5 billion and $14.9 billion a year since fiscal 2021:
Management now guides to about $20 billion of capex this year. That's more than twice 2025's $8.5 billion, and more than Tesla's cash from operations in any year on that chart. Management says spending will keep growing, and analysts expect free cash flow of -$9.9 billion in 2027 and -$7.9 billion in 2028.
Tesla has chips to pay for, too. Musk put the cost of Terafab, the chip fab Tesla may share with SpaceX, at tens of billions of dollars through early 2028 alone. Moonshots co-host Alexander Wissner-Gross sees a scenario where most of Optimus' inference runs from the cloud. On where Terafab's chips end up, he said: "my bet is it's going to data centers mostly not to robots."
Tesla can carry this for a while, with $45.4 billion of cash and investments at Sept. 30 and $30 billion of undrawn credit lines. Asked whether Tesla would rent or sell Optimus, Musk told Baron, "I think probably rent them." Blundin argued that rentals give Musk "infinite borrowing power because he's got predictable revenues." Maybe, once a rented fleet is earning money. Until then, the factories get funded by a company that earned a 2.6% GAAP operating margin in the third quarter.
Tesla trades at 183x forward earnings, well above its five-year average of 108x and below its December 2025 peak of 243x:
The way I see it, Musk's count is the easy part. Tens of millions of robots is a real market. But at 183x, investors are already paying for Tesla to win a big piece of it, and Tesla has to build the factories years before the first rental check arrives.
Of course, Optimus could ramp faster than Musk's own October timeline. The first marker is Tesla's 2027 capex guidance with its fourth-quarter results in late January, which will show how the cash splits between robots, robotaxis and chips.
