SpaceX (SPCX -4.05%) closed its $60 billion acquisition of Cursor last week, just days after releasing its latest AI model, Grok 4.6. The deal gives SpaceX an instant foothold in the enterprise AI market through Cursor's popular code editor.
Cursor brings an installed base of over 50,000 companies, including nearly two-thirds of the Fortune 500. Those users generate valuable streams of interaction data that have helped train Composer, Cursor's own coding model. That team now trains on SpaceX's own compute, and Composer 3 is expected to arrive soon.
The deal improves SpaceX's competitive position in a rapidly growing market. Recently, Bloomberg reported that Anthropic's annualized revenue had crossed $65 billion, and OpenAI's had exceeded $40 billion.

Grok is in the game
Grok 4.6 scored 61 on the benchmark Artificial Analysis Intelligence Index, matching GPT-5.6 Sol and sitting just behind the newest Claude models. On the SWE-bench that ranks large language models as tools for coding, it's in the top cluster.
The difference is price. Grok 4.6 launched at a fraction of the cost of the most advanced models, an advantage enabled by SpaceX's Colossus clusters. The company ended June with 1.4 gigawatts of nameplate compute and expects to surpass 2 gigawatts by year's end.
The next generation, Grok 4.7, is expected within weeks as xAI aims to gain ground on the latest GPT and Claude models.
What Cursor brings
Few domains in AI have become as lucrative as coding, and Cursor gives SpaceX a seat at the table. Before this acquisition, SpaceX was a laggard in that market. Now, it has two model families in Grok and Composer, the coding tools, and an AI agent in Grok Bot. Those sit on top of the company's expanding power and data center assets. This level of vertical integration provides an edge over the frontier labs, which still rent much of their capacity.
The decision to buy Cursor was a smart bet, but SpaceX still lacks a large recurring profit center like Alphabet's Search or Microsoft's Office to fund its AI ambitions. Meanwhile, the stock price will face new pressures through mid-2027 as the lock-up periods currently keeping most of its shares out of the public float expire.

Key Data Points
But if SpaceX can leverage Cursor to make its models a top choice for software developers, that would put it in the same conversation as Anthropic and OpenAI, both of which are targeting trillion-dollar-plus valuations in their upcoming IPOs.
The $60 billion price SpaceX paid for Cursor was steep, but I think it will be the key that unlocks a much larger opportunity.
