On January 5, employees at Cursor returned from the holiday weekend to an all-hands meeting with a slide deck titled “War Time.”

During the break, employees playing with Anthropic’s latest model, Opus 4.5, had experienced an uncomfortable realization: its coding abilities had advanced to the point where developers no longer needed to review every line of output. Instead of collaborating with an AI assistant inside Cursor’s code editor, developers could issue high-level instructions to autonomous agents and receive back completed features — sometimes, even the finished product. And that was a problem.

Cursor was built on a different premise. CEO Michael Truell described it to Forbes in 2024 as a kind of “Google Docs for programmers,” a collaborative editor where humans and AI refined code together.

But if the AI doesn’t need a human collaborator, why bother with the editor? If writing and editing code line by line was no longer central to a programmer’s workflow, Cursor’s central product thesis was suddenly in question.

At the all-hands, Cursor leadership warned that the months ahead would be turbulent ones. Projects might be scrapped, priorities shifted. The company’s new mandate was labeled “P0 #1”—priority zero: “Build the best coding model.”

Not the best wrapper. The best model. Call it a vibe shift. Inside Cursor, it felt like a reckoning.

Which is what makes this moment so jarring. Until recently, Cursor seemed nearly unstoppable. The company began 2025 with roughly $100 million in annualized revenue. By November, that figure had surpassed $1 billion. Its latest financing round valued the company at nearly $30 billion, minting its four cofounders as billionaires and placing Cursor among the top 20 most valuable private companies in the world.

But in the fast-moving world of AI, perceived momentum can appear – or evaporate – overnight.

By February, after Anthropic released an even more advanced version of Opus, X started to fill up with startup founders claiming their teams had ditched Cursor, arguing that model makers like Anthropic and OpenAI would absorb the coding layer themselves.

“Most of the companies I mentioned…their view is that Cursor is obsolete today,” Insight Partners founder Jerry Murdoch said on the 20VC podcast last week.

But the numbers throw that narrative into question. According to a source familiar with Cursor’s finances, annualized revenue has now crossed $2 billion, doubling within three months. And data from corporate credit card companies Ramp and Brex show continued revenue growth through February, though Ramp says Cursor’s adoption rates among businesses buying AI products are declining slightly. It’s not........
