Overview
Anysphere, Inc. is the company behind Cursor, the AI code editor that became one of the defining products of the “vibe coding” era — where developers describe what they want in natural language and AI handles much of the coding. Founded in 2022 by four MIT graduates — Michael Truell, Sualeh Asif, Aman Sanger and Arvid Lunnemark — it rose from a startup to a $29.3 billion valuation in three years, then became the target of the largest startup acquisition on record: SpaceX’s $60 billion all-stock purchase in 2026 (The Economic Times).
The identity: Anysphere, Inc. (“Cursor”)
In SpaceX’s regulatory filings, the company is named exactly once: “Anysphere, Inc. (‘Cursor’)” — the parent company behind the Cursor product (SEC 8-K). The distinction matters because most public discussion uses “Cursor” for both the company and the product. The founders’ early work explored different AI applications, including computer-aided design, before they focused on the core problem — programmers constantly switching between their editor and separate AI chatbots — and brought AI directly into the coding environment (The Economic Times).
The $29.3 billion Series D
In November 2025, Anysphere closed a $2.3 billion Series D — one of the largest venture rounds of the year — setting a $29.3 billion post-money valuation, more than triple its June valuation just six months earlier. The backer list reads like a map of the AI power structure: Accel, Thrive Capital, Andreessen Horowitz, DST Global and Coatue alongside strategic investors Nvidia and Google (Crunchbase News). The company was reportedly used by engineering teams across 64% of the Fortune 500 (The Economic Times).
The SpaceX acquisition — verified from the filing
In April 2026, SpaceX and Anysphere announced a collaboration that included an option: SpaceX could acquire the company for $60 billion or pay $10 billion for the partnership alone (The Economic Times). On June 16, 2026, SpaceX signed the Agreement and Plan of Merger: subsidiary X67 Inc. would merge into Anysphere, with Anysphere surviving as a wholly owned SpaceX subsidiary. Every Anysphere share converts into the right to receive SpaceX Class A common stock (ticker SPCX on Nasdaq), priced at the seven-day volume-weighted average before closing, based on an implied equity value of $60.0 billion (SEC 8-K). SpaceX expected the deal to close in Q3 2026, subject to regulatory approvals.
Per Forbes reporting cited by the Economic Times, the four founders each held roughly 4.5% of Anysphere — stakes worth about $2.7 billion apiece at the $60 billion valuation (The Economic Times).
What this profile does not claim
This profile does not claim the merger has closed — the SEC filing states an expected Q3 2026 closing subject to approvals, and no later regulatory confirmation was reviewed here. It does not assert a definitive founder-equity figure beyond the reported ~4.5% each. It does not claim the 64% Fortune 500 usage figure is independently audited. The strategic rationale (folding Cursor into an AI stack alongside xAI) is press analysis, not a filed statement.

- 2026
- SpaceX secures an option in April to buy Anysphere for $60 billion or pay $10 billion for a partnership.
- 2026
- On June 16, SpaceX signs an Agreement and Plan of Merger with X67 Inc. and Anysphere, Inc. ("Cursor"): X67 merges into Anysphere, which survives as a wholly owned SpaceX subsidiary, with shareholders receiving SpaceX Class A stock at a $60 billion implied equity value.
What we could not verify
These claims came up in research and could not be confirmed. They are recorded here rather than published as fact or quietly dropped. If you hold a source that settles one, please tell us.
- The SEC filing states the merger is expected to close in Q3 2026 subject to regulatory approvals; whether it closed on schedule is not asserted here beyond the filing's expectation.
- Founders' individual ~4.5% stakes (Forbes) are reported via the Economic Times, not from a directly read Forbes piece.
- The 64% of Fortune 500 usage figure is a company claim reported by the Economic Times.

3 sources (2 tier 1, 1 tier 2), each opened and read against the claim it supports. Every source is independent of the subject; no first-party material is cited. See the source policy.
Built from sources fetched and read in full: the SEC Form 8-K of Space Exploration Technologies Corp. dated June 16, 2026 (tier1 primary), the Economic Times (tier1) and Crunchbase News (tier2). The SpaceX acquisition — flagged as unverified at the research stage — was verified directly against the filed 8-K before any claim was written.
