Anysphere

Anysphere built Cursor, the fastest-growing AI-native code editor in the developer-tools market, and SpaceX now owns it — an all-stock purchase worth roughly $60 billion closed on August 14, 2026, the largest price ever paid for a startup. Cursor operates inside SpaceX's SpaceXAI division alongside xAI. Founded in 2022 by CEO Michael Truell and MIT classmates, Anysphere reached approximately $2 billion in annual recurring revenue and 360,000+ paying customers by early 2026, with over 1 million active users. The company's Series D closed in November 2025 at a $29.3 billion post-money valuation, backed by Andreessen Horowitz, Thrive Capital, NVIDIA, and Battery Ventures — and its customer base now includes NVIDIA, Stripe, and 90%+ of Salesforce developers.

Cursor is built as a fork of VS Code — same extensions, keybindings, and settings — but rebuilt from scratch with AI as the primary interface. Headline capabilities include Cursor Tab (multi-line predictive completions), Cmd+K inline editing, @-mention chat with full codebase indexing, Agent Mode for autonomous multi-file tasks, and the in-house Composer model line for multi-file orchestration — currently Composer 2.5, built on Moonshot AI's open-source Kimi K2.5 checkpoint and trained with 25-times more synthetic tasks than Composer 2 plus a new sharded-Muon distributed-training setup. Composer 2.5 is priced at $0.50 per million input tokens and $2.50 per million output ($3 / $15 for the fast variant), with double-usage promo in the first week of release. Recent 2026 additions include Bugbot (auto-detects and fixes issues in pull requests), Automations (cloud-based async agents), and JetBrains integration via the Agent Client Protocol. Cursor offers multi-model choice between Claude Opus 4.7, GPT-5.5, Gemini 3.1 Pro, and Composer.

On June 16, 2026, SpaceX agreed to acquire Cursor outright in an all-stock deal worth roughly $60 billion — its largest acquisition ever — converting the purchase option it first secured on April 21, 2026 into a definitive agreement expected to close in the third quarter of 2026. The price marks a steep premium over Cursor's $29.3 billion Series D valuation. Microsoft reportedly explored acquiring Cursor earlier in 2026 before SpaceX secured the original option. The strategic rationale is to pair Cursor's product and customer base with Colossus — SpaceX/xAI's training supercomputer (555,000 NVIDIA GPUs, scaling to 1 million by late 2026) — to train next-generation coding models. The acquisition closed on August 14, 2026, and Cursor now operates inside the SpaceX/xAI group rather than as Anysphere.

On August 17, 2026 Cursor moved beyond the editor and began hosting code. Origin — repositories, browsing and pull requests — rolled out in early beta on every paid plan, and is built so that no migration is required: GitHub repositories sit alongside Cursor-hosted ones and pull-request comments sync in both directions within seconds. The launch landed as GitHub was in the middle of an outage, one of 257 the incumbent logged over the previous year.
