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."
This comes months after SoftBank Group announced that it had invested $1.4 billion in the parent of Paytm, giving the digital payments start-up a boost as it looks to expand its user base and maintain its market lead in Asia's third-largest economy.
A source familiar with the matter said SoftBank had bought $1 billion of new shares in Paytm parent One97 Communications, equivalent to a 14.2 percent stake, and a further $400 million of existing shares. SoftBank and Paytm declined to give details.
Solar-to-telecoms conglomerate SoftBank will also get a board seat in Paytm, the Indian firm said in a statement.
