- SpaceX spent $15.83 billion on AI infrastructure in the second quarter, more than double the previous quarter and 86% of companywide capital expenditure. [1][2] - AI revenue reached $2.56 billion, while $14.1 billion of signed cloud contracts helped the segment produce positive adjusted EBITDA for the first time. [1] - The AI division still posted a $1.26 billion operating loss because adjusted EBITDA excludes $1.89 billion of depreciation and amortization and $516 million of stock-based compensation. [1] - SpaceX generated $3.47 billion of operating cash flow during the first half but recorded $28.48 billion of capital expenditure, a roughly $25 billion gap before other investing activity. [1][2]
SpaceX spent $15.83 billion on artificial-intelligence infrastructure in the second quarter, more than twice its first-quarter outlay and more than six times the revenue produced by its AI division. The scale of that buildout overshadowed a better-than-expected earnings report, with the shares falling more than 8% in after-hours trading.[1][4]
Executives argued that the spending is already producing unusually fast returns. Chief Financial Officer Bret Johnsen said on the earnings call that new compute infrastructure is achieving a payback period of less than one year, according to CNBC. The company supported that claim with $14.1 billion of signed cloud-services contracts, $1.6 billion of incremental quarterly infrastructure revenue and positive adjusted EBITDA in the AI segment.[1][3]
Those figures show genuine commercial traction. They do not resolve the larger cash-flow question. SpaceX spent $18.37 billion across all three divisions during the quarter and $28.48 billion in the first half, compared with $3.47 billion of first-half operating cash flow. The difference is being financed from the company’s enlarged balance sheet following its IPO and bond sale rather than by current operations.[1][2]
Compute contracts transformed the AI segment #
SpaceX reported second-quarter revenue of $7.81 billion, up 92% from a year earlier and above the roughly $6.9 billion expected by analysts surveyed by S&P Visible Alpha. Its net loss narrowed to $541 million from $1.01 billion, while adjusted EBITDA rose 191% to $3.54 billion.[1][4]
The AI division supplied most of the acceleration. Revenue increased 247% year over year and 213% sequentially to $2.56 billion. AI solutions and infrastructure generated $2.19 billion, while advertising contributed $367 million. The mix shows that the division’s growth came primarily from compute and AI services rather than advertising.[1]
SpaceX said several cloud-services agreements signed during the quarter represented $14.1 billion of non-cancellable contracted sales. Those agreements generated $1.6 billion of incremental AI infrastructure revenue during the quarter. The company did not identify the customers or disclose the contracts’ individual durations, pricing structures or minimum utilization requirements in its earnings materials.[1][2]
Compute capacity rose to 1.4 gigawatts from 1 gigawatt in March and 0.4 gigawatts a year earlier. SpaceX said it is continuing to expand its Colossus II data-center system. Musk said on the call that the company intends to use Nvidia chips exclusively for future infrastructure and could have up to 10 gigawatts of compute capacity by the end of 2027.[1][4]
Positive adjusted EBITDA does not mean the AI buildout is profitable #
The AI segment produced $1.15 billion of adjusted EBITDA, reversing a $609 million loss in the first quarter. Its operating result remained a $1.26 billion loss. The roughly $2.4 billion difference largely consisted of $1.89 billion in depreciation and amortization and $516 million of stock-based compensation excluded from the adjusted measure.[1]
That distinction is especially important for a capital-intensive compute provider. Depreciation is a non-cash charge in the current period, but it reflects servers, power systems and data-center equipment that required cash upfront and may become obsolete quickly. Excluding it can clarify near-term utilization economics, but it does not establish the return on the full infrastructure investment.
At the gross-profit level, the early contracts look attractive. AI revenue of $2.56 billion minus $1.11 billion in cost of revenue implies a gross margin of about 57%. Research and development consumed another $2.18 billion, while selling, general and administrative expenses totaled $532 million.[1]
Johnsen’s under-one-year payback statement therefore appears to describe the economics of newly deployed, contracted compute capacity rather than the entire AI division. That is an inference from the reported figures: SpaceX did not publish the calculation, define which costs it includes or disclose whether the estimate assumes full customer utilization.[1][3]
Starlink remains the financial counterweight #
Connectivity remains SpaceX’s largest and most profitable operating division. Revenue rose 66% to $4.29 billion, and operating income increased 79% to $1.66 billion, producing an operating margin of about 39%. Adjusted EBITDA reached $2.60 billion.[1]
Starlink ended June with 12 million subscribers, double the year-earlier count and 1.7 million above March. Average monthly revenue per user held at $66 after falling from $85 a year earlier. Consumer revenue grew 44% to $2.49 billion, while enterprise and government revenue more than doubled to $1.81 billion.[1]
The company also disclosed more than $6 billion of multi-year Starshield awards, primarily from two U.S. Space Force contracts covering low-Earth-orbit communications and sensing constellations. These awards contributed to a companywide backlog of $47.5 billion, though SpaceX did not provide a schedule for converting that backlog into revenue.[1][2]
The space division remains a development operation as much as a launch business. Its revenue rose 29% to $962 million, but it posted a $542 million operating loss after spending $1.08 billion on research and development, principally for Starship. Space capital expenditure was $1.17 billion, less than one-thirteenth of the AI division’s outlay.[1]
The cash cushion buys time, not proof #
SpaceX finished the quarter with $93.52 billion in cash and $6.49 billion in marketable securities. The balance sheet expanded after the company raised about $85.7 billion in gross IPO proceeds and completed a $25 billion bond issuance in June. The bonds carry a weighted average interest rate of 5.855% and mature between 2031 and 2056.[1][2][5]
First-half operating cash flow was $3.47 billion, while capital expenditure reached $28.48 billion. Subtracting those figures gives a simple free-cash-flow deficit of about $25 billion before acquisitions and other investing activity. Johnsen said investors should expect similar capital expenditures over the next two quarters, according to the Associated Press.[1][2][6]
SpaceX’s first public report therefore showed two AI stories at once. The commercial story improved quickly: compute contracts drove revenue, gross profit and adjusted EBITDA. The capital story became more demanding: AI absorbed 86% of quarterly capital expenditure, and the company’s reported payback claim depends on contract terms and utilization data that investors have not received.
SpaceX shares had risen 9.4% during regular trading on August 4 to $125.33 before falling more than 8% after the results. The regular-session close remained below the $135 price set for the company’s June 12 IPO.[4][5]
