Elon Musk has once again made headlines with one of his most audacious declarations to date. Standing firm in his belief that Tesla will surpass every other company on the planet, Musk is now claiming that Tesla’s market capitalization will exceed $10 trillion, catapulting it far beyond current tech titans like Nvidia, Apple, and Microsoft. He didn’t stop there.Musk is actively urging investors to seize what he calls a “golden opportunity” to buy Tesla stock before it skyrockets.

While many regard this as classic Musk-style bravado, others are beginning to wonder if, despite Tesla’s recent struggles, there might be a deeper vision at play. But with Tesla’s stock performance wavering and its core business facing headwinds, is this a moment of visionary foresight—or a delusion disconnected from reality?To put Musk’s claim in perspective, consider that Tesla’s current market cap hovers around $900 billion. For it to cross the$10 trillion mark, it would need to multiply in value more than tenfold. This would make Tesla worth more than the five most valuable companies today—combined.

That list includes Nvidia, whose AI-fueled growth has made it the poster child for the current tech boom, as well as Apple, Microsoft, Alphabet, and Amazon. Together, those companies account for over $10 trillion in total market value. And yet, Musk believes Tesla alone will exceed that sum.Such a bold claim would be easier to entertain if Tesla’s core business—its automotive division—were thriving. But that is far from the case.

In the first quarter of this year, Tesla reported a 13% drop in vehicle deliveries year-over-year, falling to 337,000 units.At the same time, its automotive revenue plummeted by 20%, a decline that outpaced the drop in deliveries due to massive price cuts implemented by the company. These cuts were a desperate attempt to maintain volume in the face of rising competition and weakening demand, especially in key markets such as China, the United States, and Europe.The much-anticipated Cybertruck has turned out to be more of a PR stunt than a game-changer. With production delays, safety questions, and tepid consumer enthusiasm, the vehicle has failed to generate any meaningful revenue. Tesla’s other promised innovations, like the Cybercab and fully autonomous vehicles, remain stuck in perpetual development.

Despite years of promises, Tesla has yet to deploy a functioning robotaxi fleet, while rivals like Waymo are already performing over 250,000 rides per week. These delays and failures have begun to erode investor confidence in Tesla’s ability to deliver on its promises.Meanwhile, Tesla’s profit margins have shrunk considerably. Over the past 12 months, its operating margin has dropped to 7.4%. With revenue falling and price cuts continuing, it is likely that this margin will contract even further in the coming quarters.Tesla has not issued long-term guidance for 2025, but forward-looking indicators suggest that the decline in sales may continue throughout the year. Without new models or breakthrough technologies reaching consumers, Tesla’s automotive business looks increasingly stagnant.And yet, amid this turmoil, Musk is undeterred. His latest pitch to investors hinges not on cars, but on robots. Musk is now placing Tesla’s future on the back of the Optimus Bot—a humanoid robot designed to perform physical tasks for humans.According to Musk, if Tesla can build and sell 100 million units of the Optimus Bot at $100,000 each, the company could generate $10 trillion in revenue. That’s not a rounding error; that is the entire vision.

However, this vision has major holes. Tesla has never demonstrated a fully autonomous humanoid robot. The versions shown to the public have been remotely controlled and extremely limited in their capabilities.For Tesla to suddenly go from zero to 100 million units sold annually would be an industrial and technological miracle unlike anything ever achieved. Moreover, even if such a product existed, it is difficult to imagine sustained global demand for millions of $100,000 robots. There is a finite number of corporations and wealthy individuals who could justify such a purchase. Without clear use cases or working models, this entire revenue stream exists solely in Musk’s imagination.Despite the lack of substance behind these claims, Musk continues to use them to drive investor enthusiasm. His cult-like following on social media and among retail investors remains strong, and his ability to influence market perception is unparalleled. But the data tells a different story.Tesla currently trades at a price-to-earnings (P/E) ratio of around 150, compared to an industry average closer to 10. For context, Toyota—one of the most successful automakers in history—trades at a fraction of Tesla’s valuation, despite having higher global sales and consistent profitability.

This means that Tesla’s current valuation is already pricing in enormous success in the future—success that has not yet materialized. With auto sales down, margins shrinking, and no major innovations hitting the market, Tesla looks more like a struggling carmaker than the next $10 trillion tech titan. And yet, Musk continues to ask investors to look past the numbers and believe in the dream.Many seasoned analysts argue that this is the wrong time to buy Tesla stock. Despite the recent dip to $275 per share, the company remains significantly overvalued given its earnings and performance outlook. There is little indication that the core business will recover in the near term. And while Musk’s vision of AI-powered robots and autonomous fleets is appealing, it remains entirely speculative.Investors would do well to examine the risks. If Tesla cannot turn around its automotive business and continues to delay its futuristic products, the stock could face continued downward pressure. Moreover, if economic conditions worsen, high-P/E growth stocks like Tesla are often the first to be punished by the market.

And yet, to Musk’s credit, some of his wildest predictions have come true. He brought electric vehicles into the mainstream when many doubted the concept. He built SpaceX into the most successful private aerospace company in history. His ability to bend reality through vision and execution is undeniable. But every bold claim must eventually meet the hard limits of physics, economics, and competition.In the case of Tesla’s path to $10 trillion, there is simply too much uncertainty, too many assumptions, and too little evidence. Unless the Optimus robot becomes the most successful product in history, or Tesla achieves technological breakthroughs far beyond anything currently on the horizon, this valuation remains a fantasy.Still, for the dreamers, Musk’s message is clear: Now is the time to buy. “This is your golden moment,” he tells investors. Whether that moment is truly golden—or fool’s gold—will depend not on words, but on results.
