However, concerns linger that selling large amounts of Arm stock could adversely affect its share price, especially since SoftBank has already borrowed $8 billion against its Arm shares.

Despite skepticism from some analysts regarding SoftBank's ability to deliver on this investment promise, Son's history of unexpected successes keeps the door open for optimism.

SoftBank, founded by Masayoshi Son in 1981, has a diverse investment portfolio that includes major players like Yahoo, Alibaba, and Nvidia, and has recently reported profits from its Vision Funds after two years of losses.

Son is a strong advocate for artificial intelligence, believing it will surpass human intelligence within the next decade and transform industries, positioning SoftBank's stake in Arm as crucial for expanding AI applications.

The uncertainty surrounding Trump's potential economic policies, including higher import taxes and immigration reforms, could complicate the inflation outlook and influence the Federal Reserve's decisions on interest rates.

As the story develops, further updates on the investment and its implications for the U.S. economy and job market are anticipated.

In previous statements, SoftBank indicated plans to invest approximately $9 billion annually in AI, although specific targets for this investment have not been disclosed.

President-elect Donald Trump is poised to announce a monumental $100 billion investment from SoftBank, spearheaded by CEO Masayoshi Son, with the ambitious goal of creating 100,000 jobs in the U.S. over the next four years.

This new investment pledge is a significant increase from the $50 billion commitment Son made in 2016, which was revealed during Trump's first term.

Trump has characterized this investment as a 'historic investment' that underscores confidence in the future of the American economy.

While the specifics of how SoftBank will finance this commitment remain unclear, potential sources include its Vision Fund or its chip design company, Arm Holdings, with SoftBank currently holding around $30 billion in cash.
