ByteDance, owner of the popular short video app TikTok, may see its plan to go public postponed until late 2022, after regulatory hurdles in China are resolved, according to three people briefed on the matter. One source told the South China Morning Post that the start-up, the world’s largest unicorn with some private investors valuing it at US$400 billion, is unlikely to receive the go-ahead from Chinese authorities to float the company before the Communist Party’s 20th congress, which is expected to take place next autumn. ByteDance valuation reaches US$400 billion in anonymous online trades With government efforts to formulate new data regulations still under way, there is little possibility that the Beijing-based firm, founded by Chinese entrepreneur Zhang Yiming nearly a decade ago, could win quick approval for an initial public offering, a second source with close ties to ByteDance investors said. In a major revision of its cybersecurity review rules proposed in July, the Cyberspace Administration of China (CAC) is seeking to demand a review of any digital platform operators holding personal data from at least one million users ahead of overseas listings. That came after the internet watchdog announced a cybersecurity probe into ride-hailing giant Didi Chuxing, citing national security grounds. The result of that review has yet to be announced, and public canvassing for the updated IPO rule only concluded recently. It is yet unclear how future cybersecurity reviews would be implemented and whether they would apply to listings in Hong Kong, a city usually not considered a “foreign” market under Chinese regulations. A third source told the Post that authorities advised ByteDance, which added a government delegate to the board of its main domestic subsidiary earlier this year, “not to rush” to go public. The sources declined to be identified as the matter is private. In response to a request for comment by the Post , a ByteDance representative reiterated its previous statement in April that the company has no IPO plans. It also denied a Financial Times report in August that it would seek to list in Hong Kong in either the fourth quarter of 2021 or early next year. ByteDance founder Zhang Yiming tops China’s under 40 business leaders list With the company’s IPO now on the back-burner, some existing shareholders have tried to cash out. Bloomberg News reported on Thursday that the US-based options trading firm Susquehanna International Group, one of ByteDance’s earliest and largest investors, is looking to sell about US$500 million of its shares, citing unidentified sources. Another shareholder recently sold its equity stakes valuing the company between US$360 billion and US$370 billion, according to the report. Trades in ByteDance shares published anonymously on Chinese internet service platforms such as 36Kr also show an active market for stakes in the company. The question of when ByteDance will go public has been a guessing game among investors for a while. Last year, the company generated more than 236 billion yuan (US$36.8 billion) in revenue – an increase of 11 per cent from a year ago, according to public financial information. Its main video sharing app in China, Douyin, has over 600 million daily active users. Will Zhang Yiming stay in charge at ByteDance after stepping down as CEO? Plans for ByteDance to expand its business in China this year, however, have run into several road bumps. The company has laid off thousands of people in its online education unit and downsized its financial arm after Beijing increased control over those industry sectors. It has also dismissed staff at its local offices in smaller cities such as Wenzhou and Jinhua in Zhejiang province, as well as Luoyang in Henan province, according to Chinese media, as the government tightened its grip on algorithms , a key part of TikTok and Douyin’s smart recommendation technology. In contrast, TikTok has thrived abroad after former US president Donald Trump failed in his attempt to ban the app in the country. The company announced last month that the app’s monthly global users reached 1 billion. Despite TikTok’s growth, 38-year-old Zhang announced in May that he would step down as chief executive of the company that he founded. He has been out of the public eye for months, apart from appearing in a photo taken in his hometown in the southeastern Fujian province in June, when he donated 500 million yuan to support local education. Zhang recently overtook Tencent Holdings founder Pony Ma as the richest person in China’s internet industry with a net worth of US$59.4 billion, according to Forbes’ real-time billionaire ranking.
