On Wednesday, Reuters reported [reuters.com] that AI bot ChatGPT reached an estimated 100 million active monthly users last month, a mere two months from launch, making it the "fastest-growing consumer application in history," according to a UBS [ubs.com] investment bank research note. By comparison, TikTok took nine months to reach 100 million monthly users, and Instagram about 2.5 years, according [barrons.com] to UBS researcher Lloyd Walmsley.
“In 20 years following the Internet space, we cannot recall a faster ramp in a consumer internet app," Reuters quotes Walmsley as writing in the UBS note.
