AI coding tool Cursor AI just pulled in another massive round of funding, and its valuation is soaring.
On Thursday, the San Francisco–based startup announced it had raised $2.3 billion, bringing its valuation to a staggering $29.3 billion, according to The Wall Street Journal. That’s more than triple its last reported valuation of $9.9 billion, following a $900 million Series C in June.
This latest round was co-led by Accel (an existing backer) and Coatue, which joined the company’s cap table for the first time. Strategic investors also included Nvidia, a major enterprise customer, and Google, one of the AI model providers powering Cursor’s system.
Thrive Capital, the firm founded by Joshua Kushner, led Cursor’s previous two funding rounds and joined this one as well.
Cursor’s CEO and co-founder, Michael Truell, told The Wall Street Journal that the new capital will go toward improving Composer, the company’s in-house AI model unveiled in October.
Right now, Cursor still depends on external large language models from OpenAI, Google, and Anthropic to power much of its coding assistant platform. But the long-term goal is for Composer to handle more of that work, potentially making Cursor less dependent on outside tech.

Cursor has quickly become one of the most talked-about AI development tools on the market, used by software teams to write, debug, and optimize code using natural language prompts.
Its explosive growth mirrors the wider boom in AI-assisted coding, where OpenAI’s Codex, Anthropic’s Claude Code, and GitHub’s Copilot are all vying for developer attention. But Cursor’s mix of enterprise deals, deep integration with Nvidia hardware, and its own upcoming AI model could give it an edge.
The next 12 months will be crucial. As OpenAI and Anthropic continue to refine their coding tools, Cursor will need to prove that it’s more than a fast-growing startup with big numbers, that it can actually build sustainable tech that developers can’t code without.
Because in the AI arms race, speed wins you attention. But substance? That’s what keeps you in the game.
