SpaceX Kills Cursor's $2B Round With $60B Buyout Option, Hands VCs a Multibillion Windfall

Cursor was 48 hours from closing a $2 billion Series C led by Sequoia when SpaceX dropped the bomb. Elon Musk's team offered a $60 billion acquisition option or a $10 billion partnership fee, instantly vaporizing the startup's funding talks. Cursor's board chose the SpaceX route, sources tell TechCrunch, effectively ending any independent fundraising plans.

The deal structure is brutal in its elegance. Either SpaceX swallows Cursor whole for $60 billion later this year, or it writes a $10 billion check for continued collaboration. No middle ground. The $2 billion round that almost happened now looks quaint by comparison.

Andreessen Horowitz and Thrive Capital, who led Cursor's early rounds, are the clear winners here. Their combined stakes could be worth north of $15 billion if SpaceX exercises the full buyout, according to Bloomberg's calculations. Not bad for a company that was valued at $400 million in its last private round.

SpaceX just pulled off the ultimate pre-IPO flex. By killing Cursor's funding round, Musk's team eliminated a potential competitor in the AI coding space while simultaneously adding a $60 billion asset to its balance sheet. Investors evaluating the IPO now see a company that doesn't just build rockets but also executes surgical strikes on the hottest AI startups.

The timing is viciously smart. With SpaceX's public debut expected this fall, the Cursor deal creates a narrative that extends far beyond launch services. Either SpaceX becomes the owner of the AI coding tool that every startup uses, or it pockets $50 billion in cash while maintaining access to Cursor's tech. Both scenarios juice the IPO valuation.

Wall Street analysts are already recalibrating their models. "This isn't just about adding revenue streams," says one tech banker who asked not to be named. "It's about demonstrating that SpaceX can move markets. That's worth a premium multiple."

Andreessen Horowitz and Thrive Capital placed early bets on Cursor when it was just another AI coding startup. Their gamble paid off spectacularly. According to Bloomberg's math, a16z's 12% stake could be worth $7.2 billion in an acquisition scenario. Thrive's 8% stake clocks in at $4.8 billion.

These aren't paper gains. If SpaceX exercises the buyout, the cash hits their funds immediately. For context, a16z's entire Fund VIII raised $9 billion. This single deal could return most of that fund's capital.

The firms declined to comment on specifics, but partners at both shops have been unusually quiet on Twitter this week. Sources close to the situation say they're in quiet celebration mode. When your seed investment turns into a 100x return, you don't tweet about it. You just count the money.

SpaceX has until December 31st to exercise the $60 billion option. Until then, Cursor operates as an independent company with a gun to its head. The partnership fee structure means they'll keep building AI tools for SpaceX regardless, but everyone knows this is temporary.

Cursor employees are already updating their LinkedIn profiles. Some are excited about the SpaceX rocket money. Others are updating their resumes, worried about culture clashes between a buttoned-up space company and a startup that let engineers work from Bali.

The broader startup ecosystem is watching nervously. If SpaceX can kill a $2 billion round with a single offer, what's stopping other cash-rich giants from doing the same? The message is clear: when the big dogs come knocking, independent fundraising might not be an option.
