SoftBank Group CEO Masayoshi Son said he was interested in investing in ride-hailing firms Uber Technologies and Lyft but had not made a decision.
"We are interested in discussing with Uber, we are also interested in discussing with Lyft, we have not decided which way," he told reporters and analysts on Monday after the company announced its quarterly results.
"Whether we decide to partner and invest into Uber or Lyft, I don't know what will be the end result," Son added.
This is the first time SoftBank has publicly indicated an interest in Uber, after having so far put funds into its rival Grab in Southeast Asia and China's Didi Chuxing. Last month, a media report said Uber shareholders and its board were mulling a stock sale to SoftBank and other investors.
