Microsoft reportedly considered acquiring AI coding startup Cursor before SpaceX’s $60 billion deal. Despite Cursor’s strong valuation, Microsoft opted not to bid, likely due to existing investments in OpenAI and Anthropic and its own AI development strategy. This underscores the intense competition in the AI coding market, where established players like GitHub Copilot compete with emerging platforms. Microsoft appears focused on fostering existing partnerships and advancing its proprietary tools amidst rapid industry shifts.

AI startup Cursor is reportedly in advanced talks for a $2 billion funding round, potentially valuing it over $50 billion post-money. Andreessen Horowitz, Nvidia, and Thrive Capital are expected to co-lead. This significant investment reflects strong investor interest in AI coding agents, a competitive field where Cursor faces rivals like Google and OpenAI. The company previously raised substantial funding and recently introduced updates enhancing AI agent autonomy and auditing capabilities.

The startup targets tech-focused companies, planning a wider rollout later this year.
