SpaceX owns Cursor. Elon Musk’s SpaceX bought Anysphere, Inc., the company that makes Cursor, in an all-stock deal valued at $60 billion that closed on August 14, 2026. Anysphere now runs as a wholly owned SpaceX subsidiary, and Musk controls SpaceX (SEC).
Who owns Cursor? The ownership chain
Level | Who | What it means |
|---|---|---|
The product | Cursor | The AI code editor and coding agent |
The company | Anysphere, Inc. | Cursor’s legal maker; its terms of service still name Anysphere |
The owner | SpaceX (Space Exploration Technologies Corp.) | Owns 100% of Anysphere since August 14, 2026 |
SpaceX’s shareholders | Public since June 2026 (Nasdaq: SPCX) | Anyone can buy shares; Cursor has no stock of its own |
Control | Elon Musk | About 84% of SpaceX’s votes after its IPO, through 10-vote Class B shares |
Cursor’s own blog put it simply: “Cursor is now a part of SpaceX” (Cursor). Its terms of service, last updated in September 2026, still welcome users to “Anysphere, Inc. … makers of the Cursor software platform” (Cursor), because Anysphere survived the merger as the legal company behind the product.
Cursor announced the deal on its blog on August 14, 2026, the day it closed.
Does Elon Musk own Cursor?
Not personally, but he controls the company that does. SpaceX is a public company with two classes of shares, and Musk’s Class B shares carry 10 votes each: after the June 2026 IPO he held about 84.4% of the voting power and elects a majority of the board (SEC). His economic stake is smaller, about 48% of the shares on an as-converted basis in his August 2026 filing (SEC). Google (about 7.2%) and Antonio Gracias’s Valor (about 6.5%) are the next-largest reported holders. Musk is also SpaceX’s CEO.
How SpaceX bought Cursor
SpaceX first signed a compute deal with Cursor in April 2026, with an option to buy the company. “Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together,” SpaceX posted on April 21 (X). The offer pre-empted a $2 billion funding round that would have valued Cursor at $50 billion (TechCrunch).
Date | Step |
|---|---|
Apr 19, 2026 | Compute agreement and option to buy Cursor signed |
Apr 21, 2026 | Announced: buy Cursor for $60B later in the year, or pay $10B for the joint work |
Jun 12–15, 2026 | SpaceX’s IPO at $135 a share; it lists on Nasdaq as SPCX |
Jun 16, 2026 | SpaceX exercises the option and signs the merger agreement (SEC) |
Aug 14, 2026 | Merger closes; Anysphere becomes a wholly owned SpaceX subsidiary |
Oct 12, 2026 | Cursor is folded into “The X Subscription” with Grok and X Premium |
Anysphere’s shares turned into 389,289,254 SpaceX Class A shares, priced on SpaceX’s average share price over the seven trading days before closing, for an implied equity value of $60 billion; no cash changed hands. Employees’ vested and unvested equity became SpaceX shares, options and restricted stock (CNBC). Had SpaceX walked away, it owed Cursor $10 billion: a $1.5 billion termination fee plus $8.5 billion of deferred compute services.
Where Cursor sits inside SpaceX
Cursor belongs to SpaceX’s Super Intelligence segment (formerly its AI segment), alongside the Grok models and the social network X. That unit came from SpaceX’s acquisition of xAI, completed on February 2, 2026, and now goes by SpaceXSI. Cursor brought in $608 million of revenue between the close and September 30, 2026, SpaceX’s quarterly report shows (SEC).
Michael Truell, who co-founded Cursor, is still its CEO; neither SpaceX’s filings nor Cursor have announced a leadership change since the deal. The sale made each of the founders a billionaire: Forbes estimated each one’s fortune at about $2.7 billion.
Who owned Cursor before SpaceX?
Four MIT students founded Anysphere in 2022: Michael Truell, Sualeh Asif, Arvid Lunnemark and Aman Sanger. Before the sale, they and Cursor’s employees held common stock, and venture investors held the rest. Its last completed round, in November 2025, raised $2.3 billion at a $29.3 billion valuation from investors including Accel, Thrive, Andreessen Horowitz, Coatue, NVIDIA and Google (Cursor). Andreessen Horowitz held about 10% and Thrive about 7% at the sale, Forbes reported (Forbes Argentina); every investor was paid in SpaceX shares.
Round | Date | Amount | Lead | Valuation |
|---|---|---|---|---|
Acquired by SpaceX | Aug 14, 2026 | All stock | SpaceX | $60B |
Round dropped for the deal | Apr 2026 | About $2B | Andreessen Horowitz, Thrive, NVIDIA and others | $50B |
Series D | Nov 13, 2025 | $2.3B | Accel and Coatue | $29.3B |
Series C | Jun 2025 | $900M | Thrive Capital | $9.9B |
Series B | Jan 2025 | Not disclosed | Thrive Capital | Not disclosed |
Series A | 2024 | $60M | Andreessen Horowitz | $400M |
Seed | Oct 2023 | $8M | OpenAI Startup Fund | Not disclosed |
What changed for Cursor users
Plans: since October 12, 2026 Cursor is sold as part of “The X Subscription,” which bundles Grok, Cursor and X Premium from $0 to $200 a month (xAI). The older Pro, Pro+ and Ultra plans are now “legacy” plans.
Models: Cursor still offers models from OpenAI, Anthropic, Google and SpaceXSI (Cursor). Third-party models cost extra, at API list prices.
OpenAI: in August OpenAI said it would stop supplying its models to Cursor, citing “our experience with Elon Musk’s companies violating contracts,” with a proposed cut-off of November 12, 2026 (CNBC). It has since temporarily extended Cursor’s access past that date, and GPT-5.6 models are still listed in Cursor.
Anthropic: Anthropic said it would keep increasing compute for Claude models in Cursor.
Is Cursor owned by xAI, OpenAI or Microsoft?
xAI: no. xAI is itself a SpaceX subsidiary, so Cursor and xAI are sister companies inside SpaceX.
OpenAI: no. OpenAI’s Startup Fund led Cursor’s 2023 seed round, and OpenAI tried to buy Anysphere in 2024 and again in 2025 (NBC), but the talks failed; it is now in a dispute with Cursor’s owner.
Microsoft: no. Cursor is built on Microsoft’s open-source VS Code, but Microsoft owns no part of it, and some of Microsoft’s own extensions no longer work in Cursor (The Register).
Is Cursor a Chinese company?
No. Anysphere is an American company based in San Francisco, and its parent, SpaceX, is incorporated in Texas. The confusion comes from Cursor’s Composer 2 model, which started from Kimi K2.5, an open-weight model from China’s Moonshot AI; Cursor says about three-quarters of the training compute was its own (TechCrunch). Moonshot owns no part of Cursor.
Can you buy Cursor stock?
Not directly. Cursor has no shares of its own, since SpaceX owns all of Anysphere. The only way to own a piece of Cursor is to buy SpaceX’s Class A shares, listed on Nasdaq under SPCX, which also gives you Starlink, the launch business, Grok and X.
Could Cursor’s owner change again?
Possibly. On October 20, 2026 SpaceX’s board formed a special committee to evaluate a combination with Tesla. No decision had been made as of SpaceX’s third-quarter report.
