SpaceX (SPAX.PVT) on Tuesday announced that it had struck a deal with AI coding tool maker Cursor, which gives SpaceX the option to purchase the startup later this year for $60 billion.<\/p>\n

\u201cSpaceXAI and @cursor_ai are now working closely together to create the world\u2019s best coding and knowledge work AI,\u201d the post said.<\/p>\n

\u201cThe combination of Cursor\u2019s leading product and distribution to expert software engineers with SpaceX\u2019s million H100 equivalent Colossus training supercomputer will allow us to build the world\u2019s most useful models,\u201d the post said. \u201cCursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.\u201d<\/p>\n

The deal is part of SpaceX CEO Elon Musk\u2019s plan to transform the rocket company into an AI behemoth ahead of its upcoming IPO. Musk merged SpaceX with his xAI startup in February.<\/p>\n

The SpaceX-Cursor tie-up also shows how AI startups continue to find larger partners in order to secure the compute needed to continue improving their models.<\/p>\n

Earlier this week, for instance, Amazon (AMZN) announced a $5 billion investment in Anthropic that will give the AI startup broader access to its trainium chips.<\/p>\n

The SpaceX IPO, targeted for June, is aiming for a $1.75 billion to $1.8 trillion valuation, potentially making it the largest in history.<\/p>\n

Notes:<\/p>\n

Platform Dependency: Cursor is a fork (modified version) of VS Code, which is owned and controlled by Microsoft.<\/p>\n

Infrastructure & Investment: Cursor relies on AI models, and with Microsoft owning a significant stake (up to 49% of profits) in OpenAI, Microsoft benefits from the increased API usage generated by Cursor.<\/p>\n

Microsoft does not own Cursor outright but controls the underlying technology (VS Code) and holds a major stake in its AI provider (OpenAI).<\/p>\n

More Notes:<\/p>\n

Yes, xAI\u2019s Grok AI models are deeply integrated into tools and platforms developed by Microsoft. As of 2025-2026, Grok and Microsoft have collaborated to host Grok models within Microsoft\u2019s enterprise ecosystem.
\nKey Microsoft tools and platforms used by\/with Grok include:<\/p>\n

\u2022 Azure AI Foundry: Grok 3, Grok 3 Mini, and Grok 4.0\/4.1 are available in Microsoft\u2019s Azure AI Foundry (formerly Azure AI Studio) for developers, featuring managed access, enterprise-grade safety, and integration with Azure\u2019s infrastructure.
\n\u2022 Microsoft Copilot Studio: Grok 4.1 Fast is available within Microsoft Copilot Studio, allowing users to build low-code, specialized copilots.
\n\u2022 Azure AI Content Safety: Microsoft\u2019s safety service is applied to Grok\u2019s models within the Azure environment to detect and filter content.
\n\u2022 Microsoft 365 (Upcoming): Elon Musk announced that Grok plugins are planned for Microsoft Office applications, including Excel, PowerPoint, and Word.
\n\u2022 Microsoft Teams: Grok integrates with Microsoft Teams through automation tools like Albato to enable AI-powered workflows, such as content generation and data analysis.<\/p>\n

Despite tensions, Microsoft\u2019s Azure AI Foundry acts as a neutral hosting platform, providing Microsoft-managed infrastructure for xAI\u2019s models.<\/p>\n
