SpaceX (SPCX) Stock Looks Above Fair Value After Recent Slide

Simply Wall St·10/15/2026 22:39:35
Listen to the news

Space Exploration Technologies has seen its share price slip recently after a strong run of headlines, which puts a sharper spotlight on a simple question for investors. Is the current valuation of SpaceX stock adequately supported by the company’s book value, or has sentiment moved ahead of the balance sheet?

  • The stock is down 7.7% year to date, which puts recent enthusiasm around SpaceX under the microscope and raises the issue of how much fundamental asset backing investors are paying for today.
  • Plans to raise about US$40b in debt to fund a large build out of AI infrastructure may support revenue potential but could also reshape the capital structure that underpins book value per share over time.
  • There is a second opinion on Space Exploration Technologies worth weighing. See what analysts think Space Exploration Technologies's shares could be worth.

The issue now is whether the relationship between SpaceX’s share price and its book value, relative to the industry average, leaves the stock looking well grounded or stretched on this single yardstick.

Does Space Exploration Technologies Look Pricey on Book Value?

P/B is a useful yardstick for Space Exploration Technologies because so much of the story is tied to the hard assets and capital intensity behind its satellite and launch infrastructure.

Right now Space Exploration Technologies trades on a P/B of 15.9x, compared with a telecom industry average of 1.6x and a peer group average around 13.9x. That is a steep premium to both the wider sector and closer comparables, which suggests the market is paying a high price for each dollar of stated equity on the balance sheet.

Because the valuation model is heavily penalising losses and balance sheet risk, this gap looks more like a warning flag about how expensively the stock screens on book value than a precise indication of where P/B "should" land. Despite the enthusiasm around SpaceX’s US$40b AI infrastructure debt plan, the current multiple already embeds a lot of optimism into the share price on this metric. Explore the numbers behind Space Exploration Technologies's P/B valuation.
