SpaceX Q3 2026 earnings: Starlink ARPU turns up, Supersmart overtakes Connectivity on capex-driven cloud revenue, Starship Flight 15 in November
SpaceX reported Q3 on 20 Oct after the US close (8-K exhibit 99.1, unaudited; cross-checked against SEC EDGAR). Three headlines. (1) Starlink consumer net adds slowed slightly, to 1.6 million from 1.7 million in Q2, but consumer ARPU turned up for the first time, to $69 (up 5% quarter on quarter, still down 17% year on year), and the enterprise and

government share rose to 41%. The price-for-volume phase is showing a turning point. (2) Total revenue was $14.575 billion, up 161% year on year. The Supersmart segment ($7.56 billion) overtook Connectivity, driven by compute-rental cloud contracts and the contribution from the Cursor acquisition ($608 million). Headline net income of $4.4 billion was inflated by $1.025 billion of other income (including $561 million related-party), $873 million of interest income and a $390 million tax benefit; core operating profit was about $2.8 billion. Capex was $19.59 billion for the quarter (84% in Supersmart). The 9M free cash flow of about -$35 billion was financed by the IPO and debt (cash and securities of $89.86 billion, debt and leases of about $38.8 billion). On the call, the CFO guided to Q1 2027 revenue of $33-37 billion on visibility from compute contracts (verbal, not in the 8-K). (3) Starship Flight 15 is due in November and will make the first dual-recovery attempt. Musk is reportedly targeting at least weekly flights by H2 2027. Governance: special committees on a Tesla-SpaceX merger are confirmed (Musk calls it a 'good idea'). A WSJ report on 20 Oct says the Ukraine Starshield geofencing was Musk's own order, given after consulting the Trump administration. That overturns last week's 'White House/military ordered' line and raises single-point-control risk. Separately, a federal court denied the DOJ's motion to dismiss the NAACP suit over gas-turbine emissions at the Memphis Colossus data centre.
Key evidence
- Starlink had 13.6 million consumer subscribers, with 1.6 million net adds in Q3 (1.7 million in Q2). The company says most new adds came from developed markets, and 'tens of thousands' of enterprise subscribers are not in this count
- Consumer ARPU was $69 a month, up 5% QoQ (about $66 in both Q1 and Q2), the first quarterly rise. It is still down 17% YoY (from $83 a year earlier)
- Connectivity segment revenue was $5.248 billion (up 69% YoY and 22% QoQ): consumer $3.121 billion (up 57%), enterprise and government $2.127 billion (up 91%)
- Connectivity segment operating profit was $2.367 billion, an operating margin of 45% (39% in Q2, 38% a year earlier). Adjusted EBITDA of $3.499 billion less capex of $1.543 billion leaves about $1.96 billion, so Starlink is generating substantial cash on its own
- Aviation: more than 3,800 aircraft installed as of 30 Sep. The 800MHz spectrum deal is expected to close in H1 2027
- The enterprise and government share of Connectivity rose from 36% to 41%, shifting the revenue mix towards higher-value customers

- Total revenue was $14.575 billion (up 161% YoY). The Supersmart segment, at $7.56 billion, now exceeds Connectivity, mainly on compute-rental cloud contracts and $608 million from the Cursor acquisition
- Operating profit was $2.79 billion. Net income of $4.4 billion includes $1.025 billion of other income (including $561 million related-party), $873 million of interest income and a $390 million tax benefit. Core operating profit is about $2.8 billion
- Capex was $19.59 billion this quarter, of which Supersmart took $16.44 billion (84%). 9M operating cash flow was $13.1 billion against capex of $48.1 billion, leaving FCF of about -$35 billion. This is funded by the IPO and debt: cash and securities of $89.86 billion, debt and leases of about $38.8 billion
- CFO guidance on the call: Q1 2027 revenue of $33-37 billion, based on visibility of compute contracts (given verbally on the call, not in the 8-K text)
- Launches: 35 this quarter (44 a year earlier), of which 23 were internal Starlink missions (vs 29). The Space segment posted a $7 million operating loss. R&D was $1.225 billion, mostly on Starship
- New contracts: 3 ISS crewed missions, 18 national security launches and 1 Starship lunar payload contract. The Louisiana launch site is targeting a first flight in 2029
- Starship Flight 15 is scheduled for November, the first attempt to recover both booster and ship. Musk reportedly says Starship will fly at least weekly by H2 2027
- Definition change to watch: 'total satellites in orbit' now includes satellites approved for deorbit, so the Q3 figure is about 400 higher than on the old basis. Back this out when comparing with history
- Musk on the call: the Tesla and SpaceX boards have each formed a special committee of independent directors to study a merger, and he personally thinks it is a 'good idea'. On the Tesla side, 50% of all outstanding shares must vote yes, a high threshold
- WSJ, 20 Oct: the Ukraine Starshield geofencing was Musk's own order, made after consulting the Trump administration in advance. This overturns the previous week's 'White House/military ordered' framing and raises single-point-control risk again. The White House and Musk have not responded, and the call did not mention it
- A federal court denied the DOJ's motion to dismiss the NAACP suit over gas-turbine emissions violations at the Memphis Colossus data centre, so the case proceeds. Compute expansion faces environmental and power-supply risk
Catalysts to watch
- November 2026: Starship Flight 15, the first attempt to recover both booster and ship
- Q1 2027: CFO guidance of $33-37 billion revenue, with compute-contract visibility as the stated basis
- H1 2027: the 800MHz spectrum deal is expected to close
- 2029: target first flight from the Louisiana launch site
- Ongoing: the Tesla-SpaceX merger special committee process (see the TSLA brief of the same day)

- Pending: the 10-Q filing with full audited numbers. Current data comes from the unaudited 8-K exhibit 99.1
- The NAACP suit over the Memphis Colossus data centre proceeds. Rulings on gas-turbine emissions could constrain compute expansion
Risks
- Headline net income of $4.4 billion is inflated relative to core operating profit of $2.8 billion by $1.025 billion of other income (including $561 million related-party), $873 million of interest income and a $390 million tax benefit. Investors who read only the headline will overrate earnings quality
- 9M FCF of about -$35 billion: the capex burn is enormous, even with $89.86 billion of cash and securities. Supersmart takes 84% of capex, a bet that compute-rental cloud contracts materialise as the CFO's visibility suggests
- Related-party revenue ($561 million of other income, plus xAI and Megapack flows via Tesla; see the TSLA brief) invites scrutiny of intercompany accounting, more so if the merger proceeds
- Starlink ARPU is still down 17% YoY despite the QoQ uptick. Price pressure is paused, not resolved
- The satellite-count definition change (about 400 higher than the old basis) is the kind of silent shift that erodes trust in disclosure. It needs flagging every time the figure is quoted

- Starshield single-point-control risk is back up: the WSJ reports that Musk himself ordered the Ukraine geofencing. The White House and Musk are silent, and the call did not address it. If governments reduce their dependence, enterprise and government revenue growth (currently 91%) is directly exposed
- The Memphis Colossus environmental suit proceeds. A ruling could cap the pace of compute expansion and add retrofitting costs
- The Starship Flight 15 dual-recovery attempt is a public technical risk. Failure would reset the Starship timeline narrative that currently supports the H2 2027 'weekly flights' target
