The Chinese technology group ByteDance, owner of the video platform TikTok, has reportedly reached a valuation of about 550 billion US dollars. The estimate is based on a planned stake sale by early investor General Atlantic, which first invested in the company in 2017 when ByteDance was valued at roughly 20 billion US dollars.
The new figure represents a significant increase compared with recent transactions. In mid-2025, a share buyback had valued the company at about 330 billion US dollars, while secondary market trading later that year suggested a value near 480 billion US dollars.
ByteDance operates some of the world’s largest social media platforms, including TikTok and its Chinese counterpart Douyin. Strong user growth, advertising revenues and expansion into artificial intelligence and digital services have contributed to the company’s rising valuation.
Although ByteDance is not publicly listed, private transactions among investors are widely regarded as indicators of market sentiment toward the company. The reported valuation underscores continued demand for shares in one of the most influential technology firms globally.
Industry observers note that such private valuations can fluctuate significantly, as they are not subject to continuous public market pricing. Nevertheless, the scale of the current estimate places ByteDance among the most valuable private companies in the world.
The planned share transfer could be completed as early as March, though details regarding the size of the stake and future ownership structure have not been disclosed.
