SpaceX 2026年第3四半期決算：全体像

What SpaceX Reported

SpaceX (Nasdaq: SPCX) published its third-quarter 2026 results as an SEC Form 8-K, Exhibit 99.1, on October 20, 2026. Revenue was $14.6 billion (vs. $5.6 billion a year earlier), income from operations $2.8 billion, net income $4.4 billion and Adjusted EBITDA $8.8 billion. Adjusted EBITDA is a non-GAAP measure that adds back items such as depreciation and share-based compensation, so it should be read alongside the GAAP figures.

Why the segment structure matters

The company reports three segments: Space (launch services), Connectivity (Starlink) and SI, short for Super Intelligence, which was previously reported as AI. SI generated $7.56 billion of the $14.58 billion in Q3 revenue, about half of the total, versus roughly 15% a year earlier ($0.81 billion of $5.58 billion). The mix of the business has therefore shifted quickly from a launch-and-broadband company toward one that also sells AI models and compute infrastructure.

Reading the release

This document contains no analyst consensus, so a beat or miss cannot be judged from it alone. What it does offer is a clean year-over-year and quarter-over-quarter comparison across all three segments.

Two readings

• Constructive: revenue nearly doubled from the prior quarter ($7.8 billion), and two of the three segments posted operating profits.
• Cautious: quarterly capital expenditure of $19.6 billion is heavy, and net income includes non-operating items.

What to watch next

The release does not state the next earnings date. Management held a live webcast at 4:30 pm ET on October 20. The 800 MHz spectrum purchase is expected to close in the first half of 2027, subject to regulatory approval.

要点1：SI部門の急拡大

Inside the SI Segment

SI (Super Intelligence) is the segment SpaceX previously reported as AI. In Q3 it earned $7.56 billion, up 195% from the prior quarter and 830% from a year earlier, according to the release.

Revenue mix

• SI solutions & infrastructure: $7.02 billion (vs. $2.19 billion in Q2 and $0.36 billion a year ago).
• Advertising: $0.54 billion (vs. $0.37 billion in Q2 and $0.45 billion a year ago).

Growth is therefore concentrated in selling compute and AI solutions rather than in advertising.

Profit: GAAP vs. adjusted

SI posted operating income of $0.43 billion, after a loss of $1.26 billion in Q2. Adjusted EBITDA was $4.95 billion, but that figure adds back $2.47 billion of depreciation and $2.04 billion of share-based compensation ($0.82 billion regular plus $1.22 billion tied to the Cursor deal). The gap between the two measures is large, which is common for capital-intensive AI infrastructure businesses.

The Cursor deal

SpaceX closed the Cursor acquisition on August 14, 2026, at an implied equity value of $60 billion. GAAP purchase consideration was $42.5 billion, and $23.4 billion of equity awards relate to post-acquisition service. Cursor contributed $608 million of revenue from closing to September 30, so Q3 includes only about six weeks of its sales.

Independent view

This structure is closer to a cloud and AI platform provider than to a traditional aerospace segment. Compute capacity (‘nameplate compute’) rose to 1.7 GW from 1.4 GW in Q2 and 0.6 GW a year earlier.

Two readings

• Constructive: SI moved to an operating profit even after a large acquisition-related expense.
• Cautious: part of the growth is acquired, and organic growth cannot be isolated from this release. The next earnings date is not stated.

要点2：稼ぎ手と投資の使い手

Who Earns, Who Spends

Connectivity: the profit engine

Connectivity (Starlink) earned $2.37 billion in operating income (vs. $1.66 billion in Q2 and $1.19 billion a year ago), an operating margin of about 45% on $5.25 billion of revenue. Adjusted EBITDA was $3.50 billion, about 67% of revenue. Consumer revenue grew 57% YoY and enterprise & government revenue 91%. Consumer subscribers reached 13.6 million (12.0 million in Q2, 7.2 million a year ago). One caveat: monthly ARPU was $69, above Q2’s $66 but below the $83 of a year earlier, so subscriber growth is outpacing revenue per user.

Capex: concentrated in SI

Total Q3 capex was $19.6 billion (Q2: $18.4 billion; a year ago: $6.9 billion), of which SI was $16.4 billion. Capex for the first nine months was $48.1 billion, about 3.7 times operating cash flow of $13.1 billion. Operating cash flow was helped by a $4.9 billion increase in deferred revenue, which reflects customer prepayments.

Balance sheet and funding

Cash was $51.3 billion and marketable securities $38.6 billion. Long-term debt was $36.1 billion, of which $10.7 billion is owed to related parties. Funding in the nine-month cash flow statement includes net IPO proceeds of $85.7 billion and $51.8 billion of new borrowings against $39.8 billion of repayments.

Independent view

The pattern resembles other large technology builders of AI capacity: profits from a mature cash-generating line fund a very large infrastructure program. Here, the cash-generating line is satellite broadband.

Two readings

• Constructive: liquidity of roughly $89.9 billion gives substantial room to keep building.
• Cautious: most capex sits in SI, so payback can only be assessed in future quarters.

質疑で深める：黒字の中身と次の注目点

From Operating Income to Net Income

The bridge ($ billions)

• Operating income: 2.79
• Interest expense: -0.68 (of which related-party 0.35)
• Interest income: +0.87
• Other income, net: +1.03 (of which related-party 0.56)
• Pre-tax income: 4.01
• Income tax benefit: +0.39
• Net income: 4.40

The $1.61 billion between operating income and net income therefore comes from financial items, other income and a tax benefit rather than from operations. More than half of the ‘other income’ line is tied to related parties, which is worth reading in the full filing.

Per-share view

Diluted EPS was $0.35 versus -$0.36 a year earlier. The weighted diluted share count rose to 12.475 billion from 2.941 billion, reflecting the IPO and the conversion of preferred stock, so per-share comparisons across periods need care. For the nine months, net loss remains $0.41 billion, so the company is not yet profitable on a year-to-date basis.

Why GAAP vs. adjusted matters

The release itself cautions that Adjusted EBITDA is not a substitute for net income. For an SEC-registered company, GAAP operating income of $2.79 billion is the cleaner measure of core profitability, and it is positive.

Two readings

• Constructive: operating profit is positive, Connectivity carries most of it, and SI turned positive after absorbing acquisition-related stock compensation.
• Cautious: SI’s profit is a single quarter, and the net income margin is flattered by non-operating items.

What to watch

SI revenue growth excluding the acquisition, and whether revenue keeps pace with capex. The next earnings date is not stated; the 800 MHz spectrum deal is expected to close in the first half of 2027.
