SoftBank Races to Secure $22.5 Billion OpenAI Funding Commitment Amid Potential $900 Billion Valuation Surge

SoftBank Mobilizes Assets to Meet Year-End Deadline

SoftBank Group is reportedly racing against a year-end deadline to finalize a massive $22.5 billion funding commitment to artificial intelligence leader OpenAI. The Japanese technology investment giant, known for its Vision Fund, is employing a range of financial maneuvers to raise the necessary capital, according to sources familiar with the matter.

The urgency stems from the need to secure the funds before the close of the year. To achieve this, SoftBank is considering:

  • The sale of stakes in marquee holdings, potentially including shares in Nvidia and T-Mobile.
  • Tapping into undrawn margin loans secured against its valuable ownership in chip firm Arm Holdings (ARM).

This commitment is seen as a strategic move, particularly as SoftBank also prepares for the potential initial public offering (IPO) of its payments subsidiary, PayPay.

OpenAI Valuation Skyrockets, Promising Paper Gains

The timing of SoftBank's commitment is proving highly advantageous. Since the initial agreement, the valuation of OpenAI has risen dramatically. The company is currently in discussions to raise additional funding from new investors, including Amazon (AMZN), which could potentially triple its valuation to close to $900 billion, one source indicated. Should the transaction be completed at this elevated level, SoftBank would realize a significant paper gain on its investment.

“SoftBank Group (SFTBY) is racing to close a $22.5 billion funding commitment to OpenAI (OPAI.PVT) by year-end through an array of cash-raising schemes, including a sale of some investments, and could tap its undrawn margin loans borrowed against its valuable ownership in chip firm Arm Holdings (ARM),” sources told Reuters.

Strategic Alignment in AI Infrastructure

The relationship between SoftBank and OpenAI extends beyond this direct funding commitment. Both entities are key investors in Stargate, a massive $500 billion initiative dedicated to building advanced AI data centers. These centers are crucial for both training and inference capabilities, which executives believe are vital for the U.S. government's broader strategy to maintain its technological lead over China in the critical field of artificial intelligence.

The use of margin loans against the Arm Holdings (ARM) stake highlights the strategic importance SoftBank places on this investment. Arm, a foundational player in the semiconductor industry, remains one of SoftBank’s most valuable assets, and leveraging it provides immediate liquidity without requiring a full divestiture of the chip designer.

Market Implications and Financing Strategy

SoftBank’s need to raise $22.5 billion quickly could lead to market activity in its publicly traded holdings, such as Nvidia (NVDA) and T-Mobile (TMUS). While the specific size and timing of any potential sales remain undisclosed, large block sales could temporarily pressure the share prices of these companies. However, the primary financing mechanism appears to be the utilization of existing credit facilities, specifically undrawn margin loans, offering a more controlled method of capital generation.

The successful fulfillment of the $22.5 billion commitment will solidify SoftBank’s position as a major backer of the world’s leading generative AI company, positioning the conglomerate to benefit substantially from the ongoing AI boom, especially given the anticipated near-$900 billion valuation of OpenAI.
