Venture capitalist Jason Calacanis predicts Tesla Inc. (NASDAQ: TSLA) will produce 1 billion Optimus humanoid robots worldwide by 2036. He argues the product will generate more value than Apple Inc.’s (NASDAQ: AAPL) iPhone.
Speaking on the This Week in Startups podcast, Calacanis stated he had recently viewed a non-public demonstration of Optimus. He claimed Tesla’s hardware is roughly "one and a half generations" ahead of competitors seen at the World Humanoid Robot Games in Beijing.
Optimus vs iPhone Value Proposition
Calacanis described Optimus as potentially "the greatest product ever made by humanity." He asserted it would sell and provide more value than the iPhone. His confidence stems from observing Tesla’s superior "brain" technology compared to robots competing in Beijing.
The World Humanoid Robot Games featured more than 2,000 robots from 666 teams. Events tested skills ranging from running and tennis to factory assembly. Reuters reported that while China showed rapid progress, robots still struggled with practical tasks like plugging in cables.
| Metric | Detail |
|---|---|
| Prediction | 1 billion Optimus units by 2036 |
| Comparison | Surpasses iPhone in value |
| Hardware Lead | 1.5 generations ahead of Beijing competitors |
Production Shifts and Scaling Challenges
Tesla is replacing its Model S and Model X production area with an Optimus line. CEO Elon Musk confirmed this shift earlier this year, ending production of both vehicles to accommodate robots. The company committed more than $20 billion to capital spending in 2026.
Tesla’s website now lists Fremont as producing Model 3, Model Y, and Optimus. Musk cautioned during the second-quarter earnings call that Optimus will be the "hardest product to scale manufacturing" due to the need for a new supply chain.
Market Skepticism and Targets
Musk has targeted 1 million robots annually from the Fremont line, with a larger Texas operation planned later. He warned that initial production would be "agonizingly slow."
Not all investors share Calacanis’ certainty. Investor Ross Gerber questioned Optimus’ near-term commercial prospects. Unitree founder Wang Xingxing suggested humanoids could still be years from their "ChatGPT moment."
What the Numbers Show
Calacanis’ projection of 1 billion units by 2036 implies massive scale relative to Musk’s target of 1 million annually. This divergence highlights the gap between long-term venture capital optimism and near-term manufacturing constraints acknowledged by Tesla leadership.
How will Tesla's $20 billion capital expenditure in 2026 impact its near-term automotive margins and cash flow while building the Optimus supply chain?
What specific regulatory or safety frameworks must be established before humanoid robots can achieve the mass adoption required to reach 1 billion units?
Could the shift of production capacity from Model S/X to Optimus alienate Tesla's premium vehicle customer base and affect brand loyalty?
