Masayoshi Son

The announcement may come at the Choose France Summit to attract foreign investment.

Son lowered his pledged shares by 19.4 million to about 154.2 million, with roughly 31% of his holdings now used as collateral.

SoftBank saw its profit rise mainly due to higher valuations of its holdings in AI and chip companies such as Nvidia and Intel.

Son overtook Tadashi Yanai, chairman and largest shareholder of Uniqlo’s parent company Fast Retailing, who held the top spot for over three years.

SoftBank has already raised at least US$24 billion in loans and bonds in 2025, making this one of its largest funding efforts to date.

Arm’s stock has risen 38% in 2025, boosting SoftBank’s borrowing capacity, and the new loan would raise total margin loans to US$18.5 billion.

His wealth is now estimated at US$31.3 billion, making him the second richest person in Japan.

SoftBank’s Vision Fund also sold nearly US$2 billion in public and private assets in the first half of 2025.

Son praised Miyakawa’s leadership and said he rarely needs to intervene in his work.

The project has yet to secure financing or start detailed discussions with banks and investors.
