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.
In a rare left-right convergence, President Trump said the US government may take equity stakes in OpenAI and xAI, while Senator Bernie Sanders is preparing a bill that would route half of major AI firms' stock into a public sovereign wealth fund. OpenAI has floated donating shares rather than selling them to seed such a fund. Anthropic is notably absent from the talks, a legacy of its February standoff with the Pentagon over usage guardrails.
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.
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.
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.
Nine California jurors unanimously ruled on May 18 that Elon Musk's lawsuit accusing Sam Altman, Greg Brockman, OpenAI, and Microsoft of "stealing a charity" by converting the nonprofit lab to a for-profit was filed too late under the statute of limitations, ending a years-long structural threat to OpenAI ahead of its reported IPO. Musk had sought between $78.8 billion and $135 billion in damages. Judge Yvonne Gonzalez Rogers said there was a "substantial amount of evidence to support the jury's finding." Musk vowed to appeal to the Ninth Circuit.
In a TechCrunch interview, Menlo Ventures partner Deedy Das argues that roughly 10,000 founders and employees at OpenAI, Anthropic, NVIDIA, Meta, and xAI have crossed 20 million dollars in personal wealth over the past five years — while engineers earning under 500,000 dollars a year increasingly fear they cannot get there from here. Das calls the split in San Francisco "the worst I've ever seen" and ties the gap to a broader "deep malaise about work" pervading even well-paid technical roles in the AI era.
The Southern Environmental Law Center, on behalf of the NAACP, filed suit alleging xAI is operating 46 natural gas turbines at its Mississippi data center after state regulators permitted only 15 of them. Mississippi treats the trailer-mounted turbines as "mobile" equipment, which it argues exempts them from federal air-pollution standards for a year — but the complaint contends federal law allows states to regulate trailer-mounted power plants as stationary sources, and that Mississippi is simply declining to enforce. The NAACP frames the unchecked emissions as worsening air quality in an already polluted region. xAI has not responded publicly. The case is the first major regulatory test of the "neocloud" pattern of standing up frontier-scale data centers on temporary fossil-fuel power.
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.
In opening-week testimony for his lawsuit against OpenAI, Elon Musk acknowledged xAI used distillation on OpenAI models when training Grok, calling it "a general practice among AI companies" and answering "partly" when pressed for a direct yes. Distillation — querying a competitor's API to teach a smaller model — has been associated mainly with Chinese labs in public discourse; the partial admission shifts that frame and raises live questions about terms-of-service compliance.
