stock market debut, even through merging with a special-purpose acquisition company (SPAC) instead of an IPO, the sources said. Details of Pony.ai's discussions with the Chinese authorities could not be learned. Pony.ai had been in exclusive talks to go public through a merger with VectoIQ Acquisition II. The deal would have been financed with a private placement from investors of roughly $1.2 billion, and the company had aimed to list by October, according to the sources.Ī spokesperson for Pony.ai said the company has no current plan or timeline to go public and declined to comment on the talks. The Cyberspace Administration of China, which has been leading the crackdown on technology companies such as Didi, did not immediately respond to a request for comment. Had Pony.ai gone ahead with the listing, it would also have faced U.S scrutiny. Securities and Exchange Commission said last month it would not allow Chinese companies to raise money in the United States unless they fully explain their legal structures and disclose the risk of Beijing interfering in their businesses. The Committee on Foreign Investments in the United States, which reviews deals of companies with foreign ties for potential national security risks, has also been scrutinizing SPAC deals. Pony.ai CEO James Peng told Reuters in June that the company was considering going public in the United States to help fund its goal of commercializing driverless ride-hailing services. He provided no details of how this would happen. SPACs, which raise money through their IPOs to buy private companies within a certain time frame, have become a popular way for self-driving tech companies to go public. In May, Plus, an autonomous truck company with operations and partnerships in China, clinched a deal to go public through a $3.3 billion merger with Hennessy Capital Investment Corp V, before China's technology crackdown.

That deal is still expected to close by the third quarter. Pony.ai, which develops and tests its autonomous driving vehicles in the United States and China, said in November that its valuation reached $5.3 billion after raising more than $1 billion in funding. In June, the company hired Lawrence Steyn, vice chairman of investment banking at JPMorgan Chase & Co, as its chief financial officer to prepare for a public listing. VectoIQ II is the second SPAC to be led by former General Motors Vice Chairman Steve Girsky, whose first SPAC struck a deal with electric truck maker Nikola Corp. It raised $345 million in an oversubscribed IPO in January.
