After meeting with Donald Trump on Tuesday, Japanese billionaire Masayoshi Son said he would invest $50 billion in the United States and "commit" to creating 50,000 new jobs.
Son said he "came to celebrate" Trump's new job, and said, "The U.S. will become great again."
As the founder and chief executive of Softbank, Son controls the U.S. telecom Sprint. Shares in Sprint spiked after the announcement was made. Son left Trump Tower escorted by the president-elect.
The financial details about the commitment and its time frame are unclear.
But Trump quickly took credit for the commitment, saying on Twitter, "Masa said he would never do this had we (Trump) not won the election!"
