The AI segment the S-1 showed deep in the red flipped to positive Adjusted EBITDA of $1.1B — funded by $15.8B of AI capex in a single quarter. Starlink hit 12M subscribers. Every figure from the filed 8-K exhibit. *Every figure below traces to SpaceX's Q2 2026 earnings release, filed August 4, 2026 as Exhibit 99.1 to Form 8-K (accession `0001628280-26-052515`), with S-1 baselines from accession `0001628280-26-036936`. Research, not investment advice.* Our [Monday preview](https://evidinvest.com/blog/aug4-2026-spacex-ghm-earnings-preview-2026-08-03) made one argument about grading [SpaceX](https://evidinvest.com/valuation/SPCX) (**[$SPCX](https://evidinvest.com/valuation/SPCX)**)'s maiden public quarter: with no earnings history to anchor on, the S-1 was the only scoreboard, and the number that mattered most was the one everyone would be tempted to skip — the AI segment that the S-1 showed losing billions after the February xAI merger. The Q2 release, filed August 4, answered exactly that question. **The headline first.** Revenue of **$7.8 billion, up 92% year over year**. Net loss narrowed to **$541 million**, from a $1.0 billion loss a year earlier. Adjusted EBITDA of **$3.5 billion, up 191%**. SpaceX ended the quarter with **$100 billion in cash and marketable securities** and a **$47.5 billion backlog** — the balance sheet the June IPO (638.9 million Class A shares, ~$85.7 billion net proceeds) and the $25 billion inaugural bond issuance were built to create. **The AI turn is the story.** The segment the preview flagged reported revenue of **$2.6 billion, up 247%** year over year, cut its operating loss by 49% sequentially to $(1.26) billion, and — the line the S-1 could not have shown — delivered **positive AI Adjusted EBITDA of $1.1 billion**. A segment that was a pure cash drain in the prospectus generated positive segment-level cash economics in its first public quarter. The engine underneath: **$14.1 billion of new Cloud Services Agreements** signed in the quarter (contracted sales), of which $1.6 billion landed as incremental AI infrastructure revenue right away, plus Grok and X subscription growth. Compute capacity reached **1.4 GW**, up from 0.4 GW a year ago. The counterweight sits in the same table, and it is enormous: **AI capital expenditure of $15.8 billion in a single quarter** — more than twice the company's entire revenue — as SpaceX built out Colossus II and beyond. Total capex across all three segments was $18.4 billion for the quarter. The positive segment EBITDA is real; so is the fact that it is being bought with capital spending on a scale almost nothing else in the filings this season approaches. Management also announced an agreement to **acquire Cursor for $60 billion**, expected to close in Q3. **Starlink kept compounding.** The Connectivity segment did **$4.29 billion, up 66%** year over year, with income from operations up 79% to $1.66 billion and segment Adjusted EBITDA up 64% to $2.6 billion. Subscribers **doubled to 12.0 million**, up 1.7 million sequentially, with new enterprise wins including American Airlines and Starlink Mobile carrier deals (SoftBank, NTT Docomo, Spark NZ). The one number to keep honest: **ARPU fell to $66, from $85** a year ago — the subscriber base is growing faster than revenue per user, the classic consumer-broadband scale trade. **Space, the original business, is now the smallest segment.** Launch and related revenue was **$962 million, up 29%**, on 38 launches and 485 metric tons to orbit, while the segment ran an operating loss of $542 million as R&D poured into Starship V3 (Flights 12 and 13 completed, the latter deploying 20 production V3 satellites). Starshield added over $6 billion in multi-year U.S. government contracts. So the preview's question resolves cleanly: the AI segment was the one to watch, and it inflected — from the prospectus's biggest loss line to positive segment EBITDA — but the maiden print reframes the whole company as a capital allocation story. Three businesses at very different points on the curve (Starlink compounding at scale, AI inflecting on gigantic spend, Space absorbing Starship R&D), funded by a fortress balance sheet. The [valuation page](https://evidinvest.com/valuation/SPCX) has the segment build and a DCF you can point at the assumption that actually decides the number: whether $15.8 billion of quarterly AI capex keeps producing $14 billion contract cohorts. *Every figure traces to accession `0001628280-26-052515` ([sec.gov](https://www.sec.gov/Archives/edgar/data/1181412/000162828026052515/earningsreleaseq22608042.htm)).
