Jefferies Warns Tesla May Become SpaceX Proxy — With a 196x P/E Risk

For Tesla investors, the bull case has long transcended auto manufacturing. But Jefferies now warns that the stock may be absorbing hype from Elon Musk’s other crown jewel—SpaceX. After SpaceX’s recent landmark event, Tesla could morph into a space arbitrage play, adding a volatile layer to its already stretched 196x forward P/E valuation.

Jefferies analyst Philippe Houchois has introduced a fresh dimension to the Tesla (TSLA) valuation debate, warning that the electric vehicle maker's stock could be increasingly influenced by Elon Musk’s private space company, SpaceX (SPCX). In a note released on June 24, 2026, Houchois maintained a Hold rating and a $375 price target on Tesla, but his overarching message was that Tesla may be transforming into a public-market proxy for SpaceX, which recently made an earth-shattering debut—likely a reference to a landmark IPO or a highly successful orbital milestone that has captured investor imagination. This concern arrives at a time when Tesla shares are already under pressure, having declined 17% over the past six months and nearly 5% in the past month, yet still trade at a daunting 196 times forward non-GAAP earnings, a multiple 67% above its five-year average. Such a premium suggests the market has long been pricing in a future far beyond vehicle deliveries, encompassing autonomy, energy storage, robotics, and artificial intelligence. The Jefferies warning adds a new layer: that SpaceX’s success may now be slipping into that narrative, raising the stakes for Tesla shareholders who might inadvertently be betting on a space company they do not directly own.

Jefferies analyst Philippe Houchois has introduced a fresh dimension to the Tesla (TSLA) valuation debate, warning that the electric vehicle maker's stock could be increasingly influenced by Elon Musk’s private space company, SpaceX (SPCX).

Tesla’s identity as a 'battleground stock' is well established. For years, bulls have argued that the company is a technology and energy powerhouse rather than a mere automaker, justifying a valuation that dwarfs any traditional car manufacturer. The recent pullback, however, underscores how sensitive the stock remains to narrative shifts. Even after shedding nearly a fifth of its value, the shares command a forward earnings multiple that most growth companies would envy. Houchois’s note essentially suggests that SpaceX’s rising prominence could amplify Tesla’s already speculative bid, because public market investors have few pure-play avenues to bet on the commercial space frontier. As a result, they may flock to Tesla as the next best thing, given Musk’s role as the bridge between the two enterprises. This dynamic risks distorting Tesla’s valuation, making it even harder to disentangle the company’s own fundamentals from the halo effect of Musk’s broader empire.

The SpaceX effect is not entirely hypothetical. Following the company’s recent breakthrough—whether it was the successful deployment of a next-generation Starship, a major NASA contract, or a Starlink-backed public offering—media and analyst attention has surged. For Tesla, this means that any positive SpaceX headline could inadvertently lift its shares, just as any setback in the space venture could trigger a sell-off. This introduces a new vector of volatility that traditional automotive analysts like Houchois find troubling. His price target of $375 reflects a more grounded assessment, one that likely accounts for steady electric vehicle growth and incremental progress in autonomy, but not for a stratospheric space premium. The note underscores the risk that Tesla’s stock could increasingly diverge from its own operating performance, turning into a multi-industry sentiment play rather than a transparent investment.
