Overview
Cursor is an AI-assisted code editor developed by Anysphere. The company started in 2022, and its product built on the familiar Visual Studio Code editor while adding code completion, natural-language editing, and conversations about a codebase.[1][2]
SpaceX acquired Cursor in August 2026. Cursor said the completed transaction would give its team more computing capacity for model training. The editor continues as a product within the new ownership group.[3]
Founding Story
Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger started Anysphere while at MIT, according to research firm Sacra. Their company focused on an interface for people to work with AI while writing software.[1]
The editor's starting point mattered. As a fork of Visual Studio Code, Cursor could keep familiar editor conventions and extensions while changing how AI assistance appeared in the workflow. In August 2024, Andreessen Horowitz announced its Series A investment, arguing that the interface between a developer and an AI model was an important part of the product.[2]
Timeline
- 2022: The founders started Anysphere.[1]
- August 2024: a16z announced its Series A investment.[2]
- June 2025: Cursor announced a $900 million Series C and reported more than $500 million in annual recurring revenue.[4]
- November 2025: The company announced a $2.3 billion Series D and said it had crossed $1 billion in annualized revenue.[5]
- April 2026: Cursor announced a SpaceX AI model-training partnership.[6]
- August 2026: Cursor confirmed its acquisition by SpaceX was complete.[3]
What They Built
Cursor combines an editor with model-assisted software development. In its 2024 investment announcement, a16z described next-edit prediction, natural-language changes, and questions about a codebase. The editor used multiple model providers and supported the VS Code extension ecosystem.[2]
The product evolved from line completion toward agents that can work on larger tasks. Cursor also announced an agreement to acquire code-review company Graphite in December 2025. That announcement said Graphite would continue independently while the teams explored integrations; it did not itself establish closing.[5][7]
Market Position
Target Customers
Cursor serves individual programmers and engineering organizations. Its own reports named NVIDIA, Uber, and Adobe among customers. Use by an organization does not disclose the number of seats or the value of its contract.[4]
Market Size
The company reported more than $500 million in annual recurring revenue in June 2025 and more than $1 billion in annualized revenue in November. These are company-reported run rates at different dates, not audited annual revenue or profit.[4][5]
Competition
Cursor competes with coding products from model providers and developer platforms. Associated Press named Claude Code and Codex as competitors and noted that Cursor also relied on models from larger AI research companies. This combination created both flexibility for developers and a dependency on external model suppliers.[6]
Business Model
Cursor sells access through individual and team subscriptions. Its current pricing also describes usage limits and separately billed access to some third-party models. Prices and plan terms can change; subscription revenue must be weighed against model-serving costs, which the public sources do not quantify for the company.[8]
Traction
Cursor reported that more than half of Fortune 500 companies used its product in June 2025. In November it said millions of developers were customers. These are company-reported adoption statements and do not specify active seats or independent retention figures.[4][5]
Outcome and evolution
The editor became a distribution surface
Building on a familiar editor gave the team an existing workflow in which to place AI assistance. Completion, codebase questions, and larger delegated tasks all addressed different parts of development. The company later identified review and collaboration as additional bottlenecks, motivating its announced Graphite deal.[2][7]
Compute became part of the acquisition rationale
In April 2026, Cursor said its model-training work had been constrained by computing capacity and announced a partnership involving SpaceX's Colossus infrastructure. SpaceX subsequently exercised an option to acquire the company. Cursor confirmed the acquisition completed on August 14. Its own statement cited access to computing capacity and continued development of Cursor and models.[6][3]
The acquisition did not end Cursor. Its current pricing lists the editor alongside Grok and X subscription features. This combination also changes the choices available to customers, including the way third-party model usage is billed.[8]
Key Lessons
- Meet developers in an existing workflow. Cursor built on a familiar editor and placed AI assistance where code was already being written.
- Separate run rate from realized results. Cursor's reported annualized figures show the company's stated pace, not audited annual profit.
- Infrastructure can shape ownership. Cursor identified computing capacity as a constraint before its SpaceX partnership and acquisition.
