Two companies are openly working together, and one has an option to buy the other.
Then the buyer's lawyer told everyone to stop talking unless they had to - and that's the strange dance now playing out between xAI and Cursor.
James Burnham, xAI's general counsel, sent guidelines to xAI staff last week telling them that contact with Cursor employees should not go beyond what is needed to run the technical partnership the two announced last month.
Burnham is not a random in-house lawyer - he joined xAI in November after serving as general counsel at DOGE through the first half of the year.
He also worked in the Trump White House and clerked for Justice Neil Gorsuch.
The warning lands in the middle of a tricky moment: Musk's SpaceX has the option, reported by Bloomberg at $60 billion, to acquire Cursor outright on xAI's behalf later this year.
Pre-deal contact between staff at two separate companies can create antitrust and securities risk, which is exactly the kind of thing general counsel get paid to head off.

xAI's coding tool, known inside the company as Macrohard, has been through more than one restart, and the team brought in two senior executives from Cursor to help rebuild it.
Cursor has become the favorite of working developers - one of the fastest-growing developer tools in recent memory by reported revenue.
xAI has the money and the compute, with its Colossus supercomputer and large fundraising rounds well known.
What it has not had is a developer product that programmers actually want to use day to day - and Grok, its chatbot, has not closed that gap against ChatGPT and Claude, even as AI tools keep pulling in users.
A working coding tool would change that story fast.
The legal memo is a tell - when a buyer asks staff to back away from the target's people, it usually means a deal is real enough that lawyers are guarding the process.
Watch for filings, a formal acquisition agreement, or further moves from Cursor to xAI.
For investors in public AI names like Microsoft, Alphabet, and Nvidia, the question is simple: does another well-funded competitor finally show up in the developer tools market?
