Microsoft eyeing startup deals for life after OpenAI

Microsoft is actively pursuing acquisitions of artificial-intelligence startups to reduce reliance on its partnership with OpenAI, according to five people familiar with the matter. The company considered buying Cursor, a code-generation startup, earlier this year but abandoned the idea due to regulatory concerns over its existing ownership of GitHub Copilot. Instead, Microsoft is now in discussions with Inception, a Stanford University-backed startup founded in mid-2024 that uses diffusion techniques—commonly applied in image and video generation—to accelerate text production. Microsoft’s venture fund M12 led Inception’s $50 million seed round in late 2025, signaling early interest. However, the startup is now negotiating with SpaceX, which recently acquired Elon Musk’s AI research firm xAI and also pursued Cursor after Microsoft withdrew. Inception has engaged a bank to seek a valuation over $1 billion, reflecting the competitive and high-stakes nature of the AI startup market, where top researchers command salaries in the tens of millions. The race to build cutting-edge AI models is intensifying, with frontier labs developing systems featuring up to 10 trillion parameters—up from 1 trillion three years ago. Inception’s diffusion-based approach, which refines multiple tokens simultaneously, could improve speed but remains unproven for scaling to massive models. Microsoft’s strategy includes integrating talent from acquisitions into existing teams, such as those led by DeepMind co-founder Mustafa Suleyman. Microsoft’s $13 billion investment in OpenAI, with $11.8 billion already disbursed, has driven growth in its Azure cloud business since the 2019 partnership. Yet the company now faces pressure to diversify, as OpenAI’s dominance and regulatory scrutiny complicate future collaboration. With AI talent in high demand and valuations soaring, Microsoft’s acquisition efforts reflect both ambition and the challenges of competing in a rapidly evolving landscape.
