Elon Musk Thinks Tesla Will Become the World's Most Valuable Company. Here's Why Its Stock Could Plunge by 70% (or More) Instead.

Tesla is facing significant financial headwinds as its passenger EV sales continue to decline, with a 1% drop in 2024 and a 13% year-over-year decrease in both Q1 and Q2 2025, leading to a 9% revenue contraction and 71% earnings plummet in Q1 2025. This downturn is largely attributed to fierce competition, especially from lower-priced Chinese EV manufacturers. Despite the recent launch of a supervised robotaxi program and CEO Elon Musk's long-term vision for autonomous mobility, Tesla's stock maintains a sky-high P/E ratio of 173.4, significantly above industry peers, indicating a potential for a 70%+ valuation correction if EV sales continue to shrink or its robotaxi business fails to rapidly scale and overcome substantial regulatory and competitive challenges.

Analysis

Tesla's financial performance is under significant pressure due to a clear and accelerating decline in its core passenger electric vehicle business, which constitutes 72% of its revenue. EV deliveries fell 1% in 2024, followed by a sharper 13% year-over-year drop in both Q1 and Q2 2025. This downturn, driven by intense competition from lower-priced Chinese EVs like BYD in key markets such as Europe, has directly impacted profitability, evidenced by a 9% revenue contraction and a 71% plummet in GAAP earnings in Q1 2025. While the company is pivoting toward a long-term vision centered on autonomous mobility with its supervised robotaxi program, this initiative faces substantial hurdles. It is still in a nascent, supervised phase and lags behind competitors like Alphabet's Waymo, which already operates a scaled, unsupervised paid service and is partnered with Uber. This creates a stark disconnect with Tesla's valuation; the stock trades at a price-to-earnings ratio of 173.4, a multiple that is nearly five times the average of its large-cap tech peers (35.4), suggesting a valuation highly dependent on the successful, timely, and dominant execution of a speculative robotaxi business that is currently unproven.

Key Decisions for Investors

• Investors should critically evaluate the significant valuation risk, as Tesla's P/E ratio of 173.4 appears disconnected from its deteriorating core business fundamentals, including declining sales and a 71% drop in earnings.
• Monitor upcoming vehicle delivery reports closely, as continued year-over-year declines would signal deepening competitive challenges from lower-cost manufacturers and further pressure on financial results.
• Assess the competitive landscape in autonomous driving, paying attention to the progress of established players like Alphabet's Waymo, as their existing scale and partnerships represent a major challenge to Tesla's future robotaxi ambitions.
• Consider the binary nature of the investment thesis, which heavily relies on the success of the FSD and robotaxi ventures to justify the current valuation, exposing the stock to substantial downside risk if these projects face regulatory delays or fail to achieve commercial dominance.
