Tesla ( TSLA) stock jumped more than 6% Friday amid speculation that CEO Elon Musk could potentially buy TikTok. The social media platform needs to find an American buyer, or it will effectively face a countrywide ban starting next week — and Musk is reportedly the most likely candidate.

Americans are going to lose access to TikTok in less than a week, unless China green-lights a sale to what Congress has deemed a non-adversary of the United States — something China is unlikely to do but might.
