SpaceX (SPCX) Stock Stays Pricey On Book Value Even After A 35% Fall

Simply Wall St·07/18/2026 00:34:47
Listen to the news

Space Exploration Technologies stock has slipped well below its IPO price over the past month, yet the latest valuation checks still point to a market price that looks rich rather than obviously cheap.

  • Over the past month, Space Exploration Technologies shares have fallen about 35.4%, which has taken some heat out of the stock but has not clearly turned it into a bargain.
  • High expectations around Starlink, orbital AI data centers and other long term projects can support a premium tag, while heavy losses and sizeable debt funding needs may weigh on what investors are willing to pay for that growth.
  • On Simply Wall St's broader valuation checks, Space Exploration Technologies currently scores 0 out of 6, which leans more toward expensive than undervalued across the standard metrics.

The issue now is whether the current share price still bakes in too much optimism, or if the recent pullback has finally brought Space Exploration Technologies closer to a more grounded valuation.

Space Exploration Technologies delivered 0.0% returns over the last year. See how this stacks up to the rest of the Telecom industry.

Has Space Exploration Technologies Run Too Far on Book Value?

P/B is a useful yardstick for Space Exploration Technologies because investors are effectively paying up today for assets that are expected to earn their keep over time.

Right now, Space Exploration Technologies trades at a P/B of 47.3x, compared with a telecom industry average of 1.5x and a peer group average of 16.9x. That is a very large premium to both its sector and closer peers, even before you factor in that the broader telecom group is not priced aggressively on book value. The model behind Simply Wall St’s checks heavily penalises the current losses and balance sheet risk, so the implied “fair” P/B comes out far below the market level and is best treated as a warning flag rather than a precise target.

Despite the recent pullback and ongoing excitement around Starlink and orbital AI data centers, the current P/B still suggests that Space Exploration Technologies stock is pricing in very optimistic outcomes relative to its asset base.

On a P/B basis, Space Exploration Technologies screens as clearly overvalued compared with both its industry and peer benchmarks.

The Bottom Line

For Space Exploration Technologies, the market multiple view still points to an overvalued stock, with a very wide gap between its book value and what peers command. Broader checks lean weak, which means the bar for future execution is high and leaves less room for disappointments around funding needs or profitability. From here, the real swing factor is whether Starlink and the wider orbital infrastructure can eventually earn returns that justify paying so far above the asset base, or whether the current premium proves hard to sustain.
