The fresh capital would form part of a larger funding round. OpenAI is seeking to raise as much as $100 billion in total from various investors.
If successful, the funding round could value OpenAI at approximately $830 billion. This would make it one of the most valuable private companies in the world.
SoftBank CEO Masayoshi Son has described his approach as an “all-in” bet on OpenAI. The executive is working to improve SoftBank’s position in the artificial intelligence sector.
The terms of the investment are still under discussion. Details could change as negotiations continue between the parties.
SoftBank shares rose 8% in Tokyo trading following news of the potential investment. The stock climbed to 4,408.0 yen in early morning trade.
OpenAI Funding Needs and Cost Pressures
OpenAI faces rising expenses to train and operate its AI models. The company is competing with major tech firms including Alphabet’s Google in the AI space.
Son previously had to scramble to gather funds for the December investment. The effort slowed most other dealmaking at SoftBank’s Vision Fund to minimal levels.
OpenAI is exploring multiple funding sources beyond SoftBank. The company is courting Middle Eastern sovereign wealth funds and venture capital investors.
The ChatGPT maker is also considering a potential initial public offering. This would provide another avenue for raising capital to support operations.
Stargate Project Investment
Both SoftBank and OpenAI are investors in Stargate. The initiative aims to build AI data centers for training and inference purposes.
Stargate represents a $500 billion investment in AI infrastructure. Executives describe the project as critical to U.S. government goals in artificial intelligence.
The data centers would help maintain American leadership over China in AI development. This aligns with national security objectives related to technology competition.
The Stargate investment shows SoftBank’s broader commitment to AI infrastructure. The company is not limiting its bets to software companies alone.
OpenAI’s participation in Stargate gives it access to computing resources. These facilities would support the development of future AI models.
Son’s aggressive investment strategy reflects confidence in OpenAI’s business model. The CEO has redirected SoftBank’s focus toward AI opportunities.
The $30 billion investment under discussion would mark one of the largest single investments in an AI company. It demonstrates the scale of capital required to compete in the current AI market.
