SpaceX agreed to acquire Cursor, the AI coding startup formerly known as Anysphere, in an all-stock deal worth roughly $60 billion — its largest purchase ever and a sharp pivot into AI software days after its record public offering. Cursor was valued near $29 billion in its last round, so the price marks a steep premium. The deal folds one of the most popular AI coding tools into SpaceX's xAI division and pits Elon Musk directly against Anthropic and OpenAI in the developer market.
The US Justice Department urged a court to let xAI keep running 57 unpermitted natural-gas turbines at its Colossus data centers near Memphis, arguing a shutdown would threaten national, economic, and energy security. The filing backs xAI against a Clean Air Act lawsuit from the civil-rights group NAACP and the Southern Environmental Law Center, who say the turbines have worsened air quality in an already-polluted region. It is a striking case of the federal government intervening to shield a frontier AI lab's infrastructure from environmental enforcement.
SpaceX began trading on the Nasdaq under the ticker SPCX, raising about $75 billion at a valuation near $1.75 trillion — the largest initial public offering in history, and a company worth more than Tesla on its first day. The listing takes Musk's merged AI arm public: xAI, the Grok chatbot, and Starlink now sit inside one firm. SpaceX's filing disclosed that xAI lost $2.4 billion last quarter as Grok usage slid, even as rival Anthropic pays it $1.25 billion a month for data-center compute.
Google will pay SpaceX about $920 million a month from October 2026 through June 2029 — roughly $30 billion in total — for access to around 110,000 Nvidia chips, capacity SpaceX first built for its own xAI division. Google Cloud called it short-term "bridge capacity" for its Gemini Enterprise platform while its own data centers scale up. The deal lands days before SpaceX's IPO, where Google already holds about a 5 percent stake, and echoes an earlier SpaceX compute arrangement with Anthropic worth roughly $1.25 billion a month.
At a JPMorgan roadshow hosted by Jamie Dimon on June 4, Elon Musk made space-based AI data centers the centerpiece of his case for SpaceX's roughly $1.5 trillion IPO, which lists this week. Launching solar-powered compute into orbit, he argued, could become "the primary means by which AI can be expanded," sidestepping the power and permitting bottlenecks that limit data centers on the ground. SpaceX, which absorbed Musk's xAI in February, plans to spend about $12.7 billion on AI this year — though critics called the pitch long on vision and short on operational detail.
SpaceX, now merged with Musk's AI lab xAI, set a fixed price of $135 per share for an offering that values the combined rocket, Starlink, and xAI group at roughly $1.75 trillion — the largest IPO on record, aiming to raise about $75 billion. The company prices on June 11 and begins trading on Nasdaq the next day under the ticker SPCX. Starlink, with about 10.3 million subscribers, is the profit engine; xAI folds frontier-AI ambitions into the same stock.
In this week's Stratechery analysis, Ben Thompson argues that SpaceX's rumored IPO at a $2 trillion valuation only makes sense if Starship enables data centers in orbit. His core thesis: terrestrial data center expansion is now constrained more by community zoning opposition than by power generation, and the existing Starlink V2 Mini satellite form factor — about 7.4 meters by 2.7 meters — is comparable to NVIDIA's NVL72 rack. Combined with Starlink's laser interconnects, the constellation already has the network topology required for distributed orbital compute; power dissipation and radiation hardening become engineering problems rather than fundamental obstacles to agentic-inference workloads.
TechCrunch reports xAI is now buying $2.8 billion more unregulated natural-gas turbines to power its Memphis-area data centers, abandoning the *"solar-electric economy"* commitment Elon Musk wrote into Tesla's 2023 Master Plan 3. The pitch for the eventual fix: SpaceX-launched orbital solar arrays that the company claims can deliver more than five-times the energy of terrestrial panels with constant illumination. A SpaceX filing argues *"terawatt-scale annual AI compute growth"* will eventually force data centers off-planet — a long-horizon framing that does not yet address the methane the Memphis turbines burn today.
According to the Wall Street Journal, OpenAI is preparing to file confidentially with the SEC within days and could list publicly as soon as September, with Goldman Sachs and Morgan Stanley leading the underwriting. The move arrives alongside Elon Musk's recently-resolved suit against the company and a parallel SpaceX IPO filing, setting up a head-to-head financial event between two of the year's most-watched offerings. Valuation and float details have not yet been disclosed.
Per SpaceX's S-1 filing, Anthropic will pay xAI $1.25 billion per month for 300 megawatts of capacity at the Colossus 1 data center in Memphis, running through May 2029 — a contract worth over $40 billion. xAI burned $6.4 billion last year and Grok usage has dropped sharply, leaving the lab with excess capacity it is now monetizing by selling to a direct competitor. The arrangement underscores how blurred the line between rival AI labs and their cloud-supplier parents has become.
TechCrunch's Sean O'Kane published a pointed editorial on the May 7 Anthropic-SpaceX deal, framing it as evidence that xAI is abandoning frontier model training to become a neocloud — renting GPUs to a rival rather than building competitive AI itself. The deal hands Anthropic all compute at xAI's Memphis-based Colossus 1 (220,000 NVIDIA GPUs, 300 megawatts) and is projected to generate $3 to $6 billion in annual revenue for the merged SpaceXAI entity. O'Kane reads it as "a major heat check before the IPO" and notes that Grok has limited traction outside X and is not used for enterprise tasks even internally at xAI. The interpretation matters: if xAI is no longer a serious frontier-model contender, the US frontier-lab landscape collapses from four labs to three (OpenAI, Anthropic, Google DeepMind).
In this week's Stratechery analysis, Ben Thompson argues that AI compute is bifurcating into three distinct workload categories that need fundamentally different hardware. Training keeps high-bandwidth GPUs (NVIDIA's lock-in); answer inference rewards token speed (Cerebras's WSE-3 packs 44 gigabytes of on-chip SRAM at 21 petabytes per second of bandwidth versus NVIDIA H100's 80 gigabytes of HBM at 3.35 terabytes per second); agentic inference, where humans aren't in the loop, mostly cares about memory capacity and cost-per-token at scale. Thompson treats Cerebras's revised IPO pricing of $150 to $160 per share (up from $115 to $125) and Anthropic's lease of 220,000 NVIDIA GPUs at SpaceX's Colossus 1 (the 300-megawatt Memphis data center) as concrete evidence that buyers are now sorting their compute spend by workload category rather than picking a single vendor.
Anthropic announced two structural changes the same day. First, **Claude Code's five-hour rate limits double across Pro, Max, Team, and Enterprise plans**, and the peak-hours throttle is removed for Pro and Max — an immediate boost for paying developers. Second, Anthropic gains access to **over 300 megawatts of compute (more than 220,000 NVIDIA GPUs) at SpaceX's Colossus 1 data center**, with capacity deployable within a month. The compute deal materially diversifies Anthropic away from its existing Amazon Trainium and Google TPU reliance and is the first time SpaceX has been named as a frontier-lab compute partner.
In a TechCrunch sit-down, Replit CEO Amjad Masad said Cursor is in talks to be acquired by SpaceX for roughly $60 billion, attributing the move to Cursor's reported "negative 23% margins." Masad framed Replit as the contrast — gross-margin-positive for over a year, 300% net revenue retention, no plans to sell — and aired a separate fight with Apple over an iOS App Store update freeze that has lasted months. He said Replit "can take it much further" before any exit.
