The flattening part is not reported, but based on estimates from a company called TickerTrends. If they were correct it would imply a sudden and unusual departure from some incredibly impressive growth. Even more unusual given the release of their industry leading Opus/Sonnet/Haiku.

The impressive growth is plausible, but it also rhymes with "bubble". There is obviously a value proposition in there, but I'm skeptical it's a trillion-dollar one. It's a machine for turning electricity and silicon into powerpoint and spotify slop
