Why hasn't anyone built this?

Imagine a data trading platform where you could apply your research skills to make money.

Things I'd like to trade the trends of:

- Ecosystem Mindshare

- ETF inflows

- Onchain Activity (Volume, Tokens Launched, etc)

- Stablecoin Growth, REV, Fees, Bridge Flows

Polymarket has had major success with the "bet on anything" theme; why isn't a "bet on data" themed platform?

@Blockworks_ @nansen_ai @MessariCrypto @DefiLlama I don't have all the angles here, so maybe this isn't feasible, but I'd love to hear any feedback!
