June 16, 2026 — Just four days after pulling off the largest IPO in history ($85 billion raised at $135/share), Elon Musk's SpaceX dropped a bombshell: it's acquiring Cursor (the AI coding platform behind Anysphere) for $60 billion in an all-stock deal. The news sent SPCX shares surging ~16% on Tuesday, briefly pushing the company's market cap past Amazon and Microsoft to claim the #4 spot among U.S. publicly traded companies.
This isn't just another tech acquisition. It's a masterclass in dealmaking, a lifeline for a struggling AI division, and a signal that the AI coding arms race has entered a new, terrifyingly expensive phase.
On Tuesday, SpaceX formally exercised an option it secured back in April 2026 — the right to acquire Cursor for $60 billion in Class A common stock, or walk away by paying a $10 billion breakup fee ($1.5 billion termination fee + $8.5 billion in computing resources).
SpaceX chose the $60 billion buy. The deal, disclosed via an SEC filing, is expected to close in Q3 2026, pending regulatory approvals.
Cursor will become a wholly owned subsidiary of SpaceX, tasked with supercharging the company's AI ambitions — specifically, revitalizing xAI's Grok models, which have been struggling badly against competitors.
Cursor was founded in 2022 by Michael Truell and three other MIT graduates. Truell is just 25 years old. In four years, he built a company valued at roughly $60 billion.
Cursor's explosive growth tells the story:
Before SpaceX came knocking, Cursor was on track to close a $2 billion funding round from Andreessen Horowitz, Thrive Capital, and Nvidia at a $50 billion valuation. Instead, Truell took a bet on joining the SpaceX empire.
"A big risk, or a big bet, that we're making," Truell told employees about the potential merger, according to Business Insider.
This is where the deal gets really interesting. The structure was surgical:
April 2026 — SpaceX secures an option to buy Cursor for $60 billion in stock, or pay $10 billion for a pure partnership. This gave SpaceX ~2 months to test Cursor's technology internally before committing.
June 12, 2026 — SpaceX IPOs at $135/share, raising $85 billion — the largest IPO ever.
June 16, 2026 — Barely 2 trading days later, SpaceX exercises the option. By now, SPCX stock was trading above $200/share, meaning the $60 billion acquisition cost only 3.4% dilution at IPO valuation.
The math is mind-bending: SpaceX's stock surged so fast post-IPO that it added roughly $1 trillion in market cap in days — enough to buy ~16 Cursors at this price.
"Elon's super currency," Fortune called it. SpaceX's surging stock effectively paid for the acquisition in just a few hours of trading.
The acquisition wasn't a luxury — it was a necessity. Here's what was happening behind the scenes at xAI:
SpaceX merged with xAI in February 2026. The Cursor acquisition is Musk's most aggressive move yet to fix the mess. In recent months, Musk posted on X that new Grok versions showed improved performance after being trained on "a lot" of Cursor data.
SpaceX pitched IPO investors on a staggering $26 trillion addressable market in AI — broken down into:
The Cursor acquisition is SpaceX's first major step toward capturing that market. But the competitive landscape is brutal:
| Player | AI Coding Market Share | Status |
|---|---|---|
| Anthropic | ~50% | Controls the lead, backed by Google |
| Cursor (now SpaceX) | ~26% | Just got $60B war chest and rocket fuel 🚀 |
| OpenAI | Significant | Still the household name |
| Other (GitHub Copilot, etc.) | Remainder | Fighting for scraps |
Thrive Capital — the VC firm holding stakes in both SpaceX and Cursor — now sits on a combined position worth over $10 billion, according to a source familiar with the figure.
This deal reshapes the AI investing thesis across multiple fronts:
1. AI Coding Valuations Just Went Nuclear — At $60 billion, Cursor set a new ceiling for AI coding tools. Any comparable startup just got a massive valuation boost by association.
2. Watch for the Anthropic IPO — With 50% market share, Anthropic is now the clear leader in AI coding. If they IPO, expect fireworks.
3. SPCX Is Now an AI Stock — SpaceX just transformed from a rocket company into a rocket + AI company. The $60 billion price tag was paid in stock, not cash — no cash burn, just dilution.
4. Nvidia & AMD Benefit Indirectly — All these AI coding models need GPUs. More AI spending = more chip demand.
Caveat from the pros: Michael Burry (of "The Big Short" fame) reportedly said he's considering shorting SPCX due to valuation concerns. At a $2.5T+ market cap just days after IPO, the stock has certainly priced in a lot of optimism.
