SoftBank's Masayoshi Son proposed the establishment of a US-Japan sovereign wealth fund, with an initial capital of about $300 billion.

On May 25, according to the Financial Times, three insiders revealed that SoftBank CEO Masayoshi Son recently proposed the establishment of a joint sovereign wealth fund between the U.S. and Japan, aimed at making large-scale investments in U.S. technology and infrastructure. This proposal has been discussed at the highest political levels in both countries and could serve as a model for other governments to deepen investment cooperation with the U.S. According to the proposed structure, the U.S. Treasury and Japan's Ministry of Finance will act as co-owners and operators of the fund, each holding significant equity, and then open it up to other limited partner investors, potentially allowing the general public in the U.S. and Japan to subscribe for shares. Insiders stated that to achieve investment goals, the fund size needs to reach a "massive" level — with initial capital potentially being $300 billion, followed by operations with high leverage.
