Cursor Challenges Anthropic: The Rapid Rise of an AI Giant

⚡

Key Takeaways

1Cursor, backed by OpenAI, reaches $2 billion in annual recurring revenue in just 33 months.

2In March 2026, Cursor transforms its intelligent editor into a platform for autonomous agents in the cloud.

3The Cursor plugin marketplace, launched in February 2026, integrates partners like Figma and Stripe.

💡Why it matters — Cursor is redefining the enterprise AI sector, threatening Anthropic's dominant position with its rapid innovations.

The Founders of Cursor

Cursor stands out among the well-funded AI coding startups. Since their initial funding round by the OpenAI Startup Fund (that is, Sam Altman) and their Series A, it has been challenging to fully appreciate what they are building as a leader in the enterprise AI space.

Rapid Growth

Cursor has achieved one of the fastest growth trajectories in SaaS history, reaching $2 billion in annual recurring revenue (ARR) by early 2026. It took Anysphere just 33 months since its founding in 2022 to surpass this milestone in February 2026. Their pivot towards Enterprise has been the main driver of this growth, with revenues doubling over the last three months (from December 2025 to February 2026).

Recent Transformations

Cursor underwent a massive transformation in early 2026, shifting from an "intelligent editor" to a platform for autonomous agents in the cloud. Their automation feature was launched on March 5. They also introduced security automations, such as an Agentic Security Review that detects security issues in new code before it goes live. These security automations, built and tested in-house, are now available for other security teams.

Why I Am Optimistic About Cursor

Cursor is one of the fastest-growing startups in the field of AI development tools, expanding at the right moment in the history of generative AI. Backed by giants like Google and Nvidia, their command-line interface (CLI) is already legendary. In 2026, Cursor generates about 60% of its revenue from enterprise clients, where large engineering organizations (such as those from Nvidia, Uber, and Shopify) have moved from pilot programs to large-scale deployments.

Comparison with Anthropic

I believe that Cursor, rather than OpenAI, will become the biggest competitor to Anthropic in enterprise AI. Anysphere, which is only a year younger than Anthropic, is by far the most promising AI coding startup entering the realm of autonomous agents.

The Impact of Plugins

Plugins are transforming Cursor, Claude Code, and Cowork into true workflow engines. Cursor launched its own plugin marketplace on February 17, with partners like Figma, Stripe, and Linear. These tools allow AI to connect directly to the tools companies use, read data, and execute complete processes autonomously.

What is "Vibe Working"?

"Vibe working" refers to an environment where AI takes care of repetitive tasks in every role. Plugins eliminate the need to act as an intermediary between AI and the tools you use, bundling skills and instructions that teach AI how to connect to your services and execute complete processes.

Plugin Comparison

Claude Code: Operates in the terminal with the largest ecosystem of plugins, including those built by partners and the community.
Cursor: Operates in its code editor and launched its marketplace with most of the same plugins as Claude Code, with prospects for expansion.
Cowork: Operates within the Claude desktop application, designed around visual interfaces and slash commands, covering functions such as sales, finance, and marketing.

Installing and Using Plugins

To install plugins, you can browse the plugins for Cowork and Claude Code here and those for Cursor there. Once installed, you can use one or more plugins in the same conversation, depending on your needs.

The impact of these innovations on the way we work is significant, and mastering the use of Cursor and its features could prove to be a valuable skill in the future.
