The fundraising comes as the truck-hailing platform is planning an offshore initial public offering (IPO) as early as next year, the sources said, with one of them adding that the venue is likely to be New York.
The Chinese company on Tuesday announced the completion of the fundraising, which was led by SoftBank's Vision Fund, Sequoia Capital, Permira and Fidelity.
Full Truck Alliance, the result of a 2017 merger between truck service platforms Yunmanman and Huochebang, connects drivers with truck owners and their mutual client base.
Existing investors, including All-Stars Investment, GGV Capital, Hillhouse Capital Group, Tencent Holding and Yunfeng Capital also joined the funding round, the company said.
Full Truck Alliance, often described as China's "Uber for trucks", did not immediately respond to Reuters queries on its valuation and IPO plans.
The sources declined to be identified as the information is confidential.
The company, which has over 10 million registered truck drivers and over 5 million truck owners on its platform, plans to use the funds for technology, service and business model innovations.
On-demand logistics service in China is crowded, with Manbang, Huolala and Kuaigou as market leaders. Didi is also hiring van drivers for logistics service.
Bloomberg News had earlier reported that the funding round at the Chinese company valued it at about $12 billion after investment.
