Prediction market has been touted as one of the potential killer apps of crypto, but no breakout product yet. Thoughts on why?

My quick takes are 1) hard to get liquidity unless huge events like a presidential election, and 2) payout conditions and odds are hard to understand.

what if someone built GMX for prediction markets? overcoming slippage issue with a CFMM

You can just replicate the book of someone else with a great book. So if at draftkings you can get 1:10 odds on Macgregor beating DWR, the AMM would show the same, and your entire order would be filled at that price

not familiar with GMX - how does that help with liquidity?
