Former President Donald Trump has an ambitious idea: create a US sovereign wealth fund that could potentially buy TikTok. The proposal, announced Monday, is part of his ongoing efforts to keep the popular app accessible to its 170 million American users.

Trump suggested the fund would operate similarly to those in countries like Norway or Saudi Arabia, which invest in assets like stocks and real estate. “TikTok could be part of this fund,” he said, adding that the US might also partner with private investors.

This idea comes as TikTok faces a deadline to sell or be banned in the US. Earlier this year, a bipartisan law gave TikTok’s Chinese parent company, ByteDance, until April to divest its stake. Trump has previously hinted at the US taking a 50% ownership position in a deal, but the sovereign wealth fund idea adds a new twist.

However, experts say the plan has major hurdles. Setting up such a fund would take time, and TikTok’s fate needs to be decided soon. Additionally, the US government owning a social media platform raises tricky questions about free speech and governance. “It gets very complicated very quickly,” one legal expert noted.

There’s also the issue of public trust. Many users have expressed concerns about the government monitoring their activity or controlling content. “Nobody wants to be on a platform owned by the feds,” one TikTok user commented.

Even if the US government manages to acquire TikTok, there’s no guarantee its users or advertisers will stick around. As the clock ticks, TikTok’s future remains uncertain—and the sovereign wealth fund idea is just one of many possibilities on the table.
