Elon Musk says Tesla Optimus is hardest product to scale, warns of supply chain challenges

Musk says Optimus will be the hardest product Tesla has ever scaled

Musk told investors Optimus has no supply chain and every part is new, as Tesla quietly dropped mass production language from its Q2 deck Elon Musk told investors on Tesla's second-quarter earnings call that Optimus will be "the hardest product to scale manufacturing that we've ever made at Tesla," warning that the humanoid robot has no existing supply chain and that every component is new. He said he wanted to "calibrate people correctly" on expectations, acknowledging that the initial production ramp will follow a normal curve but with a flat early stretch that could last longer than investors hope. Tesla also quietly removed references to Optimus mass production from its Q2 shareholder presentation, after using that language as recently as the first quarter. The admission marks a sharp change in tone from previous quarters. Last year Musk said he would be "shocked" if Tesla was not producing 100,000 Optimus robots per month within five years, and in January 2025 he projected 50,000 to 100,000 units for 2026. By January of this year he acknowledged that zero Optimus robots were doing useful work in Tesla's factories, with the more than one thousand Gen 3 units deployed across Fremont and Gigafactory Texas collecting training data rather than performing productive tasks. Musk was candid about the engineering barriers, saying Optimus needs at least human-level dexterity before it can be useful outside controlled factory settings and calling the human hand "an incredible thing" that no robotics company has managed to replicate. Tesla must also solve memory, logic, and chip packaging challenges while securing AI processors from partners including Samsung and TSMC. The robot contains roughly 10,000 unique parts, and unlike Chinese competitors that can tap an existing smartphone supply chain for actuators and precision motors, Tesla is building its manufacturing base from scratch. The financial backdrop adds pressure. Tesla reported Q2 revenue of $28 billion, up 26 percent, but adjusted earnings of 33 cents per share badly missed the 51 cents analysts expected, and operating income fell 57 percent. Capital expenditure jumped to nearly $6 billion in the quarter, part of Tesla's $25 billion full-year spending plan, pushing free cash flow to a negative $1 billion and sending shares down about seven percent in pre-market trading on Wednesday. Musk's compensation deal ties part of his payout to delivering one million Optimus robots within a decade, a target that now sits uncomfortably against his own warnings about how difficult scaling will be. Tesla has converted its Fremont Model S and Model X lines for Optimus production and is building a dedicated facility near Gigafactory Texas, but the company has stopped promising when volume output will begin. Tesla's China president has described the Shanghai Gigafactory as a "golden key" to mass-producing Optimus, though that factory has not yet begun robotics manufacturing either.

Elon Musk Says This Will Be Tesla's 'Biggest Product Ever' -- If It Can Solve the Supply Chain Issue

Elon Musk said Tesla's humanoid robot, Optimus, will be its "biggest product ever." But first, the company must build nearly the entire supply chain needed to make it. "This is going to be the hardest product to scale manufacturing that we've ever made at Tesla because everything on the robot is new," Musk told investors during Tesla's second-quarter earnings call Wednesday. Unlike electric cars, which can use established suppliers for wheels, mirrors, glass, and body panels, Optimus has no ready-made supply chain, Musk said. Tesla must develop suppliers or manufacture components itself. It also lacks enough AI chips to scale production and must solve constraints involving memory, logic, and chip packaging. Musk said suppliers are beginning to fill some of those gaps. Samsung and TSMC are investing tens of billions of dollars in semiconductor factories that could support Optimus and Robotaxi, he said, while Micron has given Tesla "very significant" allocation of memory despite what he called "pretty insane" prices.
