Verdict: A genuinely wide launch-and-Starlink moat with an erratic profit record — priced at about 91 times sales for a future it still has to earn.

SpaceX sells three things: bandwidth from orbit, rides to orbit, and — since the xAI merger — intelligence run near it. The proportions surprise people who still think of it as a rocket company. Of the $18.7 billion collected in 2025, up 33%, the largest share by far was Starlink: $11.4 billion of connectivity, 61% of revenue, from 8.9 million subscribers at the year end whose average bill has deliberately drifted down from $99 a month in 2023 to $81 in 2025 as the network chased scale.12 The launch business — the thing that made the company famous — contributed $4.1 billion across government missions, commercial payloads and rideshares; the AI segment, which carries X's advertising as well as xAI, added $3.2 billion more.3

Revenue by segment, 2025 ($18.7B)Connectivity (Starlink) — 61%Space (launch) — 22%AI (X and xAI) — 17%SpaceX IPO prospectus (Form 424B4), segment note and key business metrics
Starlink earns three-fifths of revenue; the AI segment is mostly X's advertising until 2026's cloud contracts.

The machine behind those numbers is cadence: 167 orbital launches in 2025, up from 26 in 2020, most of them carrying SpaceX's own satellites on SpaceX's own reused boosters4 — the loop where the launch company's best customer is itself, and where reusability turns each additional flight into margin rather than expense. Starlink is the annuity built on top: a subscription utility whose addressable market is every ship, plane, army and farmhouse the cable never reached.

Profit is the unsettled part. On the combined basis of its filings SpaceX lost $4.6 billion in 2023, earned $791 million in 2024 with the help of a tax benefit and other income, and lost $4.9 billion in 2025 — the price of building Starship and AI data centres while operating Falcon — though adjusted EBITDA of $6.6 billion in 2025 says the underlying machine earns money before the future is paid for.5 The June 2026 quarter showed which way the mix is moving: revenue rose 92% to $7.8 billion, Starlink subscribers doubled to 12.0 million, and AI revenue more than tripled to $2.6 billion on new cloud contracts, a third of the total.6 The market prices the future anyway: shares listed at $135 in June 2026, fell below $110 within weeks, and closed at $154.72 on 22 September, about $2.1 trillion or roughly 91 times trailing sales.7

Whether the machine defends itself — reusability's cost lead, the cadence, the Starlink network, the vertical integration — is the moat question, taken up engine by engine in The Moat below. The risks that could stall it live in the threats; the market's arguments in the insights; and the wagers the valuation already assumes — Mars, the phone in the sky, Golden Dome, compute in orbit — under Future Bets. How the three segments divide the revenue and the profit is set out segment by segment in The Revenue Lines.

The number that tests this moat
Moat Explorer calc
Revenue, and where it comes from
$7.8B in Q2 2026: Connectivity 55%, AI 33%, Space 12% (FY2025 $18.7B)

Connectivity was 64% of revenue a year earlier. AI's share rising means the company's revenue is increasingly compute rented to other AI companies.

How it's calculated: Segment revenue $4,291M, $2,561M and $962M of $7,814M (Q2 2026); Connectivity $2,588M of $4,071M (Q2 2025).

Reusability and launch cadence are a genuine lead and Starlink a network; key-person risk and unproven profit temper it.

⚠ Threats to the moat
⚠ THREAT 01
The Key-Person & Musk Risk
One founder holds the vision, the method, the control — and the controversy; the franchise and the man cannot yet be separated.
⚠ THREAT 02
The Profitability & Valuation Question
One profitable year in three and about ninety times sales — the moat is real and the economics are still a promise.
◆ What the market may be missing
◆ THE VARIANT VIEW
What the Market Isn't Pricing In
At about 91 times sales the market prices Starlink's future — the launch monopoly itself comes almost free, and it is the wider moat.
◆ THE VARIANT VIEW
Inside the Latest Quarter (Q2 2026)
The first public quarter: revenue up 92%, AI a third of it on one new cloud customer, and $18.4 billion of capital spent in three months.
