SpaceXAI and Cursor plan to release their first jointly developed AI model as soon as Wednesday, according to a staff memo reported by Reuters. The launch was pushed back from earlier this week to improve the model's efficiency. The model was trained on SpaceX's Colossus supercomputer, a cluster scaling to roughly one million H100-equivalent GPUs. SpaceX exercised its option to acquire Cursor in an all-stock transaction following a $60 billion deal set on April 21. The company holds 18,712 BTC on its balance sheet.
SpaceXAI and Cursor Delay Launch to Improve Model Efficiency
Reuters reported that SpaceXAI and Cursor 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 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.
SpaceX Exercises Cursor Acquisition Option Following April Partnership
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. SpaceX announced it had exercised the option to acquire Cursor in an all-stock transaction. The company stated the goal is building the world's most useful AI models, noting SpaceXAI has been jointly training a model with Cursor for the past few months.
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. The combined company went public on June 12 with a Nasdaq debut, hitting a $2.1 trillion valuation. The listing made Musk the world's first trillionaire on paper.
SpaceX Targets 1 Gigawatt Orbital Data Centers by 2027
SpaceX is 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. Musk has argued that space is the only way to scale AI.
For digital investors, SpaceX holds 18,712 BTC on its balance sheet, making it one of the largest corporate bitcoin holders. Musk's estimated net worth dropped $62.7 billion in a single day this week, according to Forbes data, as investors fled volatile AI trades. 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.
