Nvidia has not announced any specific collaboration with TikTok. However, it is reported that TikTok owner ByteDance is purchasing Nvidia chips to drive its AI ambitions in China, which could be seen as a form of collaboration1.
ByteDance's purchase of Nvidia chips is motivated by its goal to be the leader in AI in China and overcome export restrictions imposed by the US. While the collaboration does not involve the development of AI technology, it does involve the use of Nvidia's AI hardware by ByteDance, which could lead to increased demand for Nvidia's chips and potentially drive the company's stock higher1.
Nvidia's announcement of its partnership with ByteDance would be a significant development in the tech industry, especially given the geopolitical tensions between the US and China. However, as of now, there is no official announcement or collaboration between Nvidia and TikTok.
