SpaceX acquired Anysphere's AI coding editor, Cursor, on Friday, August 14, 2026. The Verge reported the close on the same day. Cursor is now a wholly-owned SpaceX subsidiary. Cursor said it will work on SpaceX's AI chatbot, Grok, which added an agent feature this week.

It costs $60 billion, but not in cash, in SpaceX stock. That figure isn't new. On June 16, 2026, SpaceX and Anysphere announced a merger agreement. An Aug. 14 SEC filing describes what happened at the close. X67, a SpaceX subsidiary, merged into Cursor. Cursor survived as the subsidiary. Outstanding Cursor common and preferred shares were converted into the right to receive 389,289,254 shares of SpaceX Class A common stock at an implied equity valuation of $60.0 billion. The share price used a seven-day volume-weighted average price of SpaceX stock before the close. 1,752,426 SpaceX Class A shares were received upon conversion of vested Cursor RSUs, net of tax withholding. Unvested RSUs and options were assumed and converted into approximately 29.1 million SpaceX RSUs and approximately 44.4 million SpaceX options.

That's the mechanical version of "SpaceX buys Cursor." SpaceX paper was given to employees and holders. Unvested awards rolled into SpaceX awards. The product sits inside SpaceX the company.

The journey to Friday had begun earlier. SpaceX had an option to buy Cursor for $60 billion later in the year in April 2026. If SpaceX walked away, the IPO filings described a $1.5 billion termination fee plus $8.5 billion in computing resources, often summarized as a $10 billion combined walk-away. SpaceX held back while going public. It was traded on the Nasdaq under the symbol SPCX. On 16 June, it converted the option into a signed merger, to be completed in the third quarter, subject to regulatory approvals. August 14 is that close.

For the business facts behind the deal, CNBC's reporting in June is useful. Cursor was established in 2022. It is an editor for developing, editing and reviewing code. In November, it said it had surpassed $1 billion in annualized revenue. It debuted at No. 37 on CNBC's Disruptor 50 list in 2026. The $60 billion of Class A stock was roughly 3.4% dilution at SpaceX's IPO valuation. Already in 2026, SpaceX had merged with Elon Musk's AI company, xAI. CNBC said the Cursor purchase is an effort to take on Anthropic and OpenAI, which also sell coding tools.

Data on Ramp spending cited by CNBC in June said Cursor's share of that category had fallen from 41% in June 2025 to about 26% in May, with Anthropic around half the category. SpaceX did not provide investors with a full public customer list or updated revenue breakdown at announcement. Both companies had investments from Thrive Capital. SpaceX President Gwynne Shotwell told CNBC that the partnership "makes a huge amount of sense." In April, Cursor CEO Michael Truell said he was excited to partner with SpaceX to scale Composer, Cursor's own model, calling it a step toward "the best place to code with AI." SpaceX said in an announcement it looked forward to collaborating with the Cursor team to push frontier AI capabilities further.

Closed this week is the legal deal, plus a product note: Cursor will work on Grok, and Grok just added an agent. The Verge story is short. It doesn't list a new Cursor feature for Friday. It captures the close and that direction toward Grok staffing and product.

To someone who writes UI for a living, the facts that matter in the editor are still the same facts that they were Thursday. Cursor is an AI-powered coding environment. You tell it to write, edit and proofread. After Friday, the company that owns it is SpaceX, which owns the Grok stack after the xAI merger. The filing doesn't say whether your daily editor changes. Transfer of ownership. This filing is not about a new React toolchain; it is about shares, RSUs and options.

There are a couple of numbers that are easy to mix up, so they are worth repeating in one place. The cash wire is not the $60 billion implied equity value at close. Payment will be made in SpaceX Class A shares at a seven-day average. Cursor stockholders received 389.3 million shares. 1.75 million RSUs vested. Unvested awards converted to SpaceX RSUs and options in the tens of millions. The June deal was reported to involve a dilution of 3.4% at the IPO valuation. The April backup was $1.5 billion in cash and $8.5 billion in compute if the buy didn't happen. These are the figures as recorded. Treat social posts that round them differently as secondary.

Timeline, compact: 2022, Cursor founded. November (reported 2025), annual revenue $1 billion. April 2026, SpaceX option. May 2026, SpaceX IPO process in public view. Signed merger on June 16, 2026. Effective merger August 14, 2026. Same day, The Verge reports Cursor will work on Grok and is part of SpaceX.

It is also fair to state what we do not learn from these sources. We do not have a publicly available, detailed map of when Cursor systems move into Grok, or what systems they are. We don't have the internal customer list for Cursor at SpaceX. There is no guarantee that the pricing, models and Composer roadmap remain frozen. A change of owner is an acquisition close. If there are any product changes, that will be later news.

Short take: the news is the close, not a different way to write CSS. If you're an existing Cursor user, the change documented today is ownership and the team is being pointed at Grok. Read your diffs the same way you read them yesterday.
