Cursor

Sacra estimates that Cursor hit $4B in annualized revenue in May 2026, up from $1.2B at the end of 2025.

[SpaceX](https://www.cnbc.com/quotes/SPCX/) on Tuesday [announced](https://www.sec.gov/Archives/edgar/data/1181412/000162828026043411/spaceexplorationtechnologi.htm) it entered a formal agreement to buy the [artificial intelligence](https://www.cnbc.com/ai-artificial-intelligence/) startup Cursor for $60 billion worth of stock, a hotly anticipated deal.

On Tuesday, [Musk's SpaceX announced](https://www.businessinsider.com/spacex-cursor-coding-xai-deal-acquisition-2026-4) that it struck a deal with Cursor, giving it the right to acquire the AI coding startup for $60 billion or pay $10 billion for Cursor's work if it's not acquired.

"The combination of Cursor's leading product and distribution to expert software engineers with SpaceX's million H100 equivalent [Colossus training supercomputer](https://www.businessinsider.com/elon-musk-xai-data-center-colossus-power-memphis-2025-4) will allow us to build the world's most useful models," SpaceX said in a statement posted on X. "Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together."

AI coding startup Cursor is nearing new funding in which the four-year-old company would raise at least $2 billion in fresh capital, according to four sources familiar with the matter. Returning investors Thrive and Andreessen Horowitz are expected to lead the financing at a $50 billion valuation, prior to the new capital injection, the people said.

Cursor is an AI-powered coding platform where in-editor agents must respond inside the editor feedback loop, making worst-case latency under concurrency a hard requirement. Cursor partnered with Together AI to deploy production inference on NVIDIA Blackwell (GB200 NVL72 / HGX B200), optimize the stack end-to-end, and stand up a repeatable path from new weights to a production-like test endpoint via quantization (TensorRT-LLM + NVFP4).

Today, we’re pleased to announce a new round of financing: our Series D of $2.3B at a $29.3B post-money valuation. We’re excited to deepen our work with existing investors, including Accel, Thrive, and Andreessen Horowitz, and welcome new partners Coatue, NVIDIA, and Google.

On Thursday, Cursor announced a $2.3 billion funding round that valued the company at $29.3 billion, as originally reported by the [Wall Street Journal](https://www.wsj.com/tech/ai/the-ai-coding-startup-favored-by-tech-ceos-is-now-worth-29-3-billion-14c72c02?st=9CAcjj&reflink=desktopwebshare_permalink). This round more than doubles the company’s previous valuation of $9.9 billion, which it achieved in its [$900 million Series C round](https://techcrunch.com/2025/06/05/cursors-anysphere-nabs-9-9b-valuation-soars-past-500m-arr/) in June.

We’ve also crossed $1B in annualized revenue, counting millions of developers and many of the world’s most accomplished engineering organizations as our customers.

Composer is a mixture-of-experts (MoE) language model supporting long-context generation and understanding. It is specialized for software engineering through reinforcement learning (RL) in a diverse range of development environments.

We natively train our models at low precision by combining our MXFP8 MoE kernels with expert parallelism and hybrid sharded data parallelism, allowing us to scale training to thousands of NVIDIA GPUs with minimal communication cost.

The final result is a large-scale model optimized for high-speed use as an agent in Cursor.

Today, we’re announcing new funding to improve Cursor, $900 million at a $9.9 billion valuation from Thrive, Accel, Andressen Horowitz, and DST.

We’re also happy to share that Cursor has grown to over $500 million in ARR and is used by over half of the Fortune 500, including NVIDIA, Uber, and Adobe.

Anysphere, the maker of AI coding assistant Cursor, has raised $900 million at a $9.9 billion valuation, [Bloomberg reported](https://www.bloomberg.com/news/articles/2025-06-05/anysphere-hailed-as-fastest-growing-startup-ever-raises-900-million). The round was led by returning investor Thrive Capital, with participation from Andreessen Horowitz, Accel, and DST Global.

Using Fireworks AI Inference stack, Cursor achieved a remarkable speed bump compared to vanilla inference and their previous GPT-4 deployment.
