SoftBank Eyes $25B Stake in OpenAI Amid $40B AI Funding Surge

OpenAI is reportedly nearing a massive $40 billion funding round led by Japan’s SoftBank Group, according to Bloomberg. The investment could make SoftBank the largest backer of the ChatGPT creator after Microsoft. The round also includes participation from Magnetar Capital, Coatue Management, and Altimeter Capital.

Bloomberg noted SoftBank may contribute up to $25 billion, reflecting CEO Masayoshi Son’s bold strategy to dominate the artificial intelligence landscape. This comes on the heels of a $500 billion joint initiative between SoftBank and OpenAI—dubbed Project Stargate—aimed at building expansive AI infrastructure in the U.S., including data centers to boost OpenAI’s computing capabilities.

Increased compute power is critical for OpenAI’s performance, especially with the recent upgrade of its GPT-4o model to support image generation. SoftBank’s investment aligns with its broader vision to lead in next-generation tech innovation, placing AI at the core of its future plans.

However, the surge in AI infrastructure spending has raised concerns. Microsoft reportedly canceled several data center leases in the U.S. and Europe over the past six months due to oversupply worries. Similarly, Alibaba Chairman Joe Tsai recently warned of an emerging AI data center bubble in the U.S., as industry focus shifts from large model training to more efficient, inference-based applications.

Despite these cautionary signals, OpenAI’s continued expansion and SoftBank’s aggressive AI push underline the race to build foundational infrastructure for the future of artificial intelligence. The deal, if finalized, would mark one of the largest private investments in the AI sector to date, reinforcing OpenAI’s status as a global leader in generative AI.
