SpaceX Financials: September 2026 Update

The market values SpaceX at $1,865.22B as of September 1, 2026, on trailing twelve-month revenue of $23.04B. The implied revenue multiple sits near 81x, a premium that reflects Starlink’s recurring subscriber base, a swelling government contract book, and the market’s long-dated bet on Starship.

Key points

• Market cap rose to $1,865.22B (from $1,818.43B at the August update), with revenue TTM steady at $23.04B.
• The stock dipped below its $135 IPO price briefly in late August following a share unlock and headlines about increased Chinese launch competition before recovering.
• Nvidia disclosed a $21B SpaceX stake at the end of Q2, and roughly a dozen family offices accumulated about $3.8B in SpaceX holdings in August alone.
• SpaceX announced a planned $100B second Starbase in Louisiana, with construction targeted for 2027 and potential Starship flights by 2029.
• A Washington Post-tracked run of government contract wins underscores how federal revenue is becoming a larger component of the company’s top line.

How does the valuation look right now?

At $1,865.22B, SpaceX is roughly 10x the size of Boeing ($184B market cap, $94B revenue TTM) on a fraction of Boeing’s revenue. The gap is almost entirely multiple-driven: Boeing trades near 2x sales while SpaceX trades at 81x. Lockheed Martin ($138B, $77B revenue) and Northrop Grumman ($82B, $43B revenue) sit in the same 1-2x sales band as Boeing. The distance between SpaceX and any aerospace peer is not a reflection of today’s revenue but of what investors assign to Starlink’s addressable market and to Starship’s eventual economics.

Nvidia disclosed a $21B position in SpaceX at the end of Q2, a figure that illustrates how large the crossover between the AI and space-infrastructure investment theses has become. Family offices added another $3.8B in disclosed stakes during August, a pace of institutional accumulation that suggests the post-IPO price discovery is not finished.

What happened to the stock in August?

The share unlock in late August was the month’s most significant price event. SPCX slipped more than 2% over the week surrounding it, briefly trading below the $135 IPO price. The concurrent news cycle around China’s LandSpace and its reusable-rocket progress added pressure. Both are normal dynamics for a recently listed company: unlock windows bring supply, and competition headlines bring second-guessing. The stock recovered as institutional buying absorbed the unlock supply.

The brief dip is worth framing against the longer trajectory. SpaceX listed at a reported pre-IPO valuation of $800B in December 2025 and now trades at more than twice that level, so the August volatility was a correction of a few percentage points within a post-listing gain of roughly 130%.

What does the operational news add?

Three August developments matter for the revenue picture, even if none of them moves a filed number today.

First, the Louisiana Starbase announcement signals a capital commitment of up to $100B and a construction start in 2027. A second launch site of that scale expands throughput for both commercial and government missions, which has direct implications for future launch revenue and for Starlink’s ability to sustain and grow its constellation.

Second, the string of federal contract wins reported by the Wall Street Journal reinforces the view that government revenue is becoming a structurally larger share of SpaceX’s mix. The deregulatory environment cited in that reporting reduces friction on new awards.

Third, SpaceX is building an in-house natural gas trading desk. Energy is a meaningful operating cost for a company running rocket engines and data centers at scale. Internalizing that function is an operating-margin play, not a revenue story, but it reflects the same vertical-integration logic that has defined SpaceX’s cost structure since the Falcon 1 days.

NASA’s Dragonfly mission, confirmed for a 2028 Falcon Heavy launch, adds another anchor contract to the manifest. It is a single mission, but it extends the visible government backlog.

How do the comparables read?

Company	Market Cap	Revenue TTM	Multiple
SpaceX (SPCX)	$1,865B	$23.0B	81x
Boeing (BA)	$184B	$94.0B	2.0x
Lockheed Martin (LMT)	$138B	$77.0B	1.8x
Northrop Grumman (NOC)	$82B	$42.9B	1.9x

The traditional defense primes cluster tightly between 1.8x and 2.0x sales. SpaceX’s multiple is in a different category entirely, one that only makes sense if Starlink alone is underwriting a substantial portion of that premium and Starship’s commercial potential is treated as a call option on top. Whether that framing holds depends on how quickly the company can convert Starlink subscriber growth and government awards into visible earnings. Filed quarterly results will be the mechanism that either validates or pressures the multiple from here.
