Key Takeaways
SpaceXAI and Cursor plan to ship their first joint AI model as soon as Wednesday, per a staff memo.The model was trained on SpaceX’s Colossus cluster, scaling to roughly 1 million H100-equivalent GPUs.SpaceX, which holds 18,712 BTC, exercised its option to buy Cursor after a $60 billion deal set in April.
Preparing For Launch, No Pun Intended
SpaceXAI, the artificial intelligence (AI) arm of Elon Musk’s SpaceX, is preparing to release its first jointly developed AI model with Cursor as soon as Wednesday. Reuters reported that the companies had pushed back a launch planned for earlier this week in order to improve the model’s efficiency.
The model is set to ship inside both Cursor, the popular AI code editor, and Grok Build, SpaceXAI’s developer-facing product. Training has been running on SpaceX’s Colossus supercomputer, a cluster scaling to roughly one million H100-equivalent graphics processing units (GPUs).
The launch would mark the first product of a rapid corporate courtship. SpaceX announced it had exercised its option to acquire Cursor in an all-stock transaction, writing:
“SpaceX has exercised the option to acquire Cursor in an all-stock transaction with the goal of building the world’s most useful AI models. For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon.”
From Partnership to Powerhouse
The Cursor deal traces back to April 21, when SpaceX and the startup announced a partnership to jointly build coding-focused AI, with SpaceX holding an option to buy Cursor outright for $60 billion. As Bitcoin.com News reported at the time, the option period was expected to run through the end of 2026, a window Musk’s company did not need.
SpaceX acquired Musk’s separate AI venture xAI in February 2026 in an all-stock deal valuing the combined entity at roughly $1.25 trillion, uniting rockets, satellites, and frontier AI models under one roof. The combined company then went public, hitting a $2.1 trillion valuation on its June 12 Nasdaq debut, a listing that also made Musk the world’s first trillionaire on paper.
The company’s ambitions extend well beyond code editors given Musk has argued that space is the “only way to scale” AI, with SpaceX chasing 1 gigawatt of orbital data centers by 2027 and mass-producing “AI satellites” at its new 11-million-square-foot Gigasat factory in Texas.
Why Crypto Markets Are Watching
For digital investors, SpaceX is more than an AI story owing to the fact that the company holds 18,712 BTC on its balance sheet, making it one of the largest corporate bitcoin holders (Musk’s other ventures too have a long history of moving digital asset markets with product announcements and offhand posts alike).
The launch also comes during a bruising stretch for Musk’s personal fortune as his estimated net worth dropped $62.7 billion in a single day this week, according to Forbes data, as investors fled volatile AI trades.
In any case, the joint model enters a market where OpenAI, Anthropic, and Google ship frequent upgrades, and where coding assistants have become the industry’s most closely watched commercial battleground.
