Hi all. I've been using Polymarket and Kalshi for a while and recently got really into the idea of building something similar myself. The concept makes total sense to me but once I start digging into the "how" I hit a wall.
Like — do you even need to build everything from scratch or can you use existing protocols? How do platforms actually decide who wins a market? What stops people from manipulating thin markets?
Also curious about the business side — how do these platforms even make money if fees are so low?

dude i went through the same thing lol you don't need to build from scratch. can build on kalshi/polymarket apis, use protocol stuff like gnosis CTF, or full custom. depends on how much control you want resolution is the part everyone underestimates btw. oracles sound simple until your first edge case this basically answers everything you're asking: interexy.com/how-to-create-a-prediction-market-pl… saved me a ton of time when i was figuring this out
