- Didi Chuxing raises over $4 billion in funding from investors including Japan's Softbank
- Funds will be used for international expansion, artificial intelligence and new business initiatives
- Didi's international push will be a threat to Uber, which is also looking abroad for growth
China's ride-hailing giant Didi Chuxing has raised over $4 billion in its latest round of funding, the company said on Thursday, posing a challenge to its U.S. rival Uber in its efforts to branch out overseas.
The latest investment values Didi at over $50 billion, according to Reuters, and equips it with the cash needed to aggressively pursue expansion opportunities abroad.
Didi said it intends to use the proceeds to "scale up investments in AI (artificial intelligence) talent and technologies, to further build up its intelligent driving and smart transportation capabilities, and to bring more innovative and diversified transportation services to broader communities around the world."
Didi said the fundraising attracted both Chinese and international investors.
Softbank of Japan said in an email to CNBC that it participated in the funding. The company did not disclose how much it invested.
Abu Dhabi state fund Mubadala Capital also invested in the funding round, the Wall Street Journal reported, citing sources. Mubadala did not immediately respond to a CNBC request for comment.
In late November, Mubadala CEO Khaldoon Al Mubarak told CNBC his firm invested in SoftBank's $93 billion Vision Fund — the largest tech fund ever put together — which is also pouring cash into Chinese companies.
Didi's global push will be a threat to Uber.
The two companies have been in a slow-moving war for years. In 2016, Didi muscled Uber out of its home base of China. Uber had rolled out its ride-hailing services in 60 different cities there, with 150 million trips driven per month through its platform. But Uber was also racking up losses of more than $1 billion in China annually.
Didi has also invested in Uber's rivals globally, including U.S.-based Lyft, Brazil-based 99 and Singapore-headquartered Grab.
