What Happened to Anysphere, Inc. (doing business as Cursor)?
Cursor AI, an AI-native code editor founded in 2022, experienced unprecedented growth, reaching $4 billion in annualized revenue by May 2026. It was acquired by SpaceX for $60 billion in an all-stock deal, which closed on August 14, 2026, integrating it into SpaceXAI. However, on August 29, 2026, OpenAI announced it would terminate Cursor's access to its models by November 12, 2026, citing distrust of SpaceX's adherence to terms of service.
Quick Answer
Cursor AI, initially Anysphere, Inc., rapidly grew into a leading AI-native code editor, achieving a $29.3 billion valuation by late 2025 and $4 billion in annualized revenue by May 2026. In August 2026, it was acquired by SpaceX for $60 billion, becoming a wholly owned subsidiary of SpaceXAI to leverage its vast computing power. However, this acquisition led to OpenAI terminating Cursor's access to its models, effective November 12, 2026, due to concerns over SpaceX's past contractual compliance.

🔍Deep Dive Analysis
Founded in 2022 by MIT students Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger, Anysphere, Inc., operating as Cursor, quickly emerged as a significant player in the AI coding landscape. The company's core product, Cursor, is an AI-native code editor built on a fork of Visual Studio Code, designed to enhance developer productivity through natural-language instructions and advanced AI agents.
Cursor's growth trajectory was exceptionally rapid, often described as the fastest-scaling SaaS company in history. After an $8 million seed round in October 2023, it secured a $60 million Series A in August 2024, valuing the company at $400 million. By January 2025, Cursor had crossed $100 million in annual recurring revenue (ARR), escalating to over $500 million ARR by June 2025 following a $900 million Series C round that valued it at $9.9 billion. This explosive growth continued, with a $2.3 billion Series D round in November 2025 pushing its valuation to $29.3 billion and ARR past $1 billion. By May 2026, Cursor's annualized revenue had soared to $4 billion, with projections of exceeding $6 billion by year-end.
The company's product evolution was marked by a shift towards 'agentic development,' where the AI could autonomously handle complex, multi-file tasks, moving beyond simple autocomplete. Despite its success, Cursor faced intense competition from rivals like Anthropic's Claude Code and GitHub Copilot, leading to an internal 'emergency all-hands meeting' in January 2026 to address competitive pressures. Some early criticisms also pointed to Cursor's overinvestment in AI features at the expense of basic IDE functionality.
A pivotal turning point occurred in April 2026 when SpaceX announced an option to acquire Cursor's parent company, Anysphere, for $60 billion, or engage in a $10 billion joint work agreement. This deal was largely driven by Cursor's need for massive computing power for model training and SpaceX's desire to integrate AI capabilities into its broader ecosystem, particularly through its SpaceXAI division (which absorbed xAI). SpaceX exercised this option, and the $60 billion all-stock acquisition officially closed on August 14, 2026, making Cursor a wholly owned subsidiary of SpaceXAI.
The most recent development, as of August 29, 2026, is OpenAI's announcement to terminate Cursor's access to its models by November 12, 2026. OpenAI cited a lack of confidence that SpaceX would adhere to its terms of service, referencing past contractual non-compliance by other Elon Musk-owned entities like X (formerly Twitter) and xAI. This decision escalates the ongoing feud between Elon Musk and OpenAI CEO Sam Altman, posing a significant challenge for Cursor as it transitions to relying more heavily on SpaceXAI's internal models and compute infrastructure.
