Ask HN: What are the algorithms used by predictions markets like Polymarket?
I am curious how prediction markets like polymarket and kalshi work behind the scenes. I assume it&#x27;s more like stock options than sports betting.<p>Is there something like a market maker to help provide liquidity?<p>Is it setting probabilities&#x2F;prices using something like black-scholes?<p>How would you design a very simple prediction market MVP?
