Anysphere, the startup behind the AI-powered code editor Cursor, has skyrocketed to a $9 billion valuation, attracting major investors like Thrive Capital and Andreessen Horowitz.
While its rapid growth has made waves, the real story lies in the missed opportunity of FTX’s liquidators. What started as a small investment in Cursor now represents a multi-million-dollar missed opportunity.
San Francisco-based Anysphere, the startup behind the AI-powered code editor Cursor, has secured a significant funding boost that, according to sources familiar with the matter, has raised its valuation to an estimated $9 billion.
The latest round, totaling $900 million, was led by Thrive Capital, an early investor in OpenAI, with additional backing from Andreessen Horowitz, Accel, and others.
Founded in 2022 by four MIT alumni in their twenties, Anysphere has quickly risen to prominence in the generative AI space. Just months ago, the company raised $105 million at a $2.5 billion valuation, making this new deal a remarkable tripling in value in a short period.
The dramatic leap in valuation is primarily attributed to explosive revenue growth. By April, Anysphere’s annual recurring revenue had soared to approximately $200 million, placing it among the fastest-scaling software startups on record.
Cursor’s $900 million funding round underscores a remarkable surge in confidence around AI development tools. But what’s making waves is the connection to Alameda Research and the now-collapsed crypto exchange FTX.
Alameda Research, the trading firm once controlled by FTX and led by Sam Bankman-Fried’s ex-partner Caroline Ellison, initially invested $200,000 in Cursor during its early stages.

Following Bankman-Fried’s conviction and FTX’s fall into bankruptcy, liquidators decided to sell Alameda’s stake in Cursor for the same $200,000 the firm invested initially. In retrospect, that choice has cost them an estimated $500 million in unrealized value, given the current Cursor’s evaluation.
Cursor has captured the attention of tech giants and developers with its AI-powered software development toolkit, writing nearly 1 billion lines of working code daily.
The tool accelerates productivity by enabling programmers to use natural language to direct the AI instead of writing code manually, which is especially valuable for highly sought-after coding skills.
Despite competing with tools like GitHub Copilot, Cursor counts tech powerhouses such as Stripe, OpenAI, and Spotify among its clients, along with notable AI researchers like Andrej Karpathy.
Karpathy, a former Tesla and OpenAI engineer, even coined the term “vibe coding” to describe the almost trance-like process of creating software with Cursor’s AI.
