I’ve been thinking about prediction markets around online creators — does this already exist?

I’ve been noticing how prediction markets in crypto are mostly limited to things like sports, politics, or token prices. Do you guys think there’s room for more unconventional or niche categories? Like markets built around online creators or entertainment trends. Not sure if that’s something people would actually use or if it runs into liquidity/regulation issues, but curious if anyone has seen projects experimenting in that direction.
