Uber Technologies Inc. is at risk of losing out on another big chunk of the global market.

Grab, the leading provider of ride-hailing services in Southeast Asia, said Monday it raised $2 billion from SoftBank Group Corp. and China¡¯s Didi Chuxing and expects to receive another $500 million from new and existing backers.

The money will help Grab, which already dominates the region, defend its turf against Uber in one of the San Francisco company¡¯s most important global markets after retreats from China and Russia.
