Perplexity AI submitted a revised merger proposal to TikTok’s Chinese parent ByteDance as the popular video-sharing app stares down a national ban, according to multiple reports. Under the new proposal, the US government would own up to half of the company after a future initial public offering, a source familiar with the matter told CNBC.

The revised proposal allows for a new structure merging Perplexity AI and TikTok's U.S. business. The U.S. government could acquire up to a 50 percent nonvoting stake after a public offering valued at $300 billion or more. ByteDance would maintain equity in the new entity but cede control to a U.S. board.
