Version 2

SpaceX has secured roughly $26 billion in annual AI compute commitments from two contracts: Anthropic pays $1.25 billion per month for the full 220,000-GPU Colossus 1 supercluster [1][2], and Google pays $920 million per month for 110,000 Nvidia GPUs at xAI data centers from October 2026 through June 2029 [3][4]. Both deals were disclosed in connection with SpaceX's June 12, 2026 IPO, which is reportedly 2x oversubscribed with roughly $150 billion in demand for a $75 billion offering [6]. SpaceX characterizes its AI business as targeting a $23 trillion market [6], while skeptics argue the implied $2 trillion company valuation is not supportable on current revenue fundamentals [10][11].

The IPO is the test for whether SpaceX's compute revenue is priced as durable infrastructure or a temporary revenue line: a sustained $2 trillion valuation would set a public market benchmark for AI infrastructure companies. The outcome also reveals how investors weigh multi-year compute contracts that concentrate strategic dependence in a single Musk-controlled entity.

SpaceX acquired xAI in February 2026, gaining control of the Colossus 1 supercluster — a 220,000-GPU data center in Memphis — and quickly positioned it as a third-party AI compute supplier. Anthropic agreed to lease the full cluster for $1.25 billion per month, roughly $15 billion per year [1][2]. In early June 2026, Google disclosed through IPO-related SEC filings that it agreed to pay $920 million per month for access to 110,000 Nvidia GPUs at xAI data centers, from October 2026 through June 2029, totaling approximately $30 billion [3][4]. Together, the two contracts commit roughly $2.17 billion per month — about $26 billion annually — from two of the highest-profile AI organizations to a single Musk-controlled entity [5].

Both deals surfaced in the weeks surrounding SpaceX's planned June 12 IPO. The Google contract was disclosed through SEC filings one week before that date [3]. As of June 6, the $75 billion offering is reported to be approximately two times oversubscribed, with around $150 billion in investor demand [6]. SpaceX's own filings frame its AI business as targeting a $23 trillion market and argue that space-based infrastructure can enable AI compute capacity beyond what Earth-based companies can achieve [6]. Morgan Stanley has projected SpaceX revenue could reach $3.4 trillion by 2040, with xAI's compute rental business as the primary long-run growth driver [7].

The deals and IPO have drawn competing interpretations. Bullish commentators argue SpaceX has entered a new category — AI infrastructure as a commodity — with leverage comparable to energy or launch markets [8]. The implied approximately $8,400 per GPU per month rate in the Google deal has been cited as repricing SpaceX's entire public offering story [9]. Critics from ProfG and investor Pierre Rochard argue the $2 trillion implied valuation doesn't hold up against current revenue multiples, noting that space and telecom historically drove nearly all of SpaceX's actual revenue [10][11][12]. A structural critique from infrastructure observers holds that renting Colossus to outside customers shows xAI failed to generate sufficient internal AI demand — commercially convenient for SpaceX's IPO but an implicit signal about xAI's own product traction [13][14]. Grok, xAI's public-facing AI, counters that Google's need for third-party GPUs reflects Gemini Enterprise demand outrunning Google's internal build-out, framing the rentals as market-driven [15].

A structural feature of the arrangement noted by observers is the circular capital flow: Google is a major investor in Anthropic, Anthropic pays SpaceX $1.25 billion per month for compute, and Google now also pays SpaceX $920 million per month directly [16]. Both Anthropic and SpaceX are separately preparing public offerings — Anthropic filed a confidential S-1 in early June 2026 [17] — requiring each to disclose the financial and competitive risks of their interdependence at scale. A parallel story involves space-based compute: SpaceX has filed details on orbital data center satellite plans [18], and a startup called Starcloud raised $170 million at a $1.1 billion valuation for space-based compute [19], though technical debate over whether space-based cooling is economically viable remains open [20][21].
