Prior to the election, SoftBank said Saudi Arabia's Public Investment Fund (PIF) would be the lead partner in the fund and could invest up to $45bn over the next five years. SoftBank expects to put in at least $25bn. Several other large, unnamed investors are in talks on their participation and could bring the total size of the new fund up to $100bn, SoftBank said. Son, who wore a red tie and red sweater under his suit jacket, told reporters his company would create jobs by investing in startup companies in the United States. "We are going to invest $50bn into the US and commit to create 50,000 new jobs," Son said, adding that he saw a lot of "deregulation" under a Trump administration. Trump and Son did not give a timeline for the investment. Trump's four-year term will begin after his January 20 inauguration.Masa (SoftBank) of Japan has agreed to invest $50 billion in the U.S. toward businesses and 50,000 new jobs....

SoftBank formed and announced this $100 billion fund before you were elected. But cool story, bro. https://t.co/uH6fpnYJY6— Chris Sacca (@sacca) December 7, 2016US-listed shares of SoftBank gained 3% to $30.99. Son had hoped to merge Sprint with T-Mobile US to take on US market leaders AT&T Inc (T.N) and Verizon Communications Inc. Shares of Sprint briefly reached their highest level in 2-1/2 years, soon after Son's comments. They closed up 1.5% to $8.17 in heavy trading, ending well below session highs. Shares of T-Mobile US were up 1.8% at $55.99. It was not immediately clear how much of SoftBank's investment had been disclosed before. Softbank said on November 7, the day before the US election, it planned to make future large-scale investments via the $100bn tech fund, rather than on its own, to avoid growing already-bloated debt.

The Dow Jones industrial average closed at another record level on Tuesday, its 11th new high since the November 8 vote. Should the SoftBank fund grow as large as $100bn, it would be one of the world's largest private equity investors and a potential kingpin in the technology sector. SoftBank has also been stepping up investment in new areas. It agreed to buy UK chip design firm Arm Holdings in July in Japan's largest ever outbound deal.
