Show HN: PredictionHunt – Compare probabilities across prediction markets

https://predictionhunt.com/

Hey HN - my friend and I built Prediction Hunt, a site that aggregates data from prediction markets like Kalshi, Polymarket, and PredictIt into one simple dashboard.

It updates every few minutes, shows probabilities for each event, and even highlights arbitrage opportunities when markets disagree. I made it after getting tired of flipping between tabs just to see how each market was pricing the same question. Would love feedback on the product, data accuracy, and any ideas for what you'd want to see next.

It's so cool that you made this. Are you planning on adding more categories? Like trending topics or culture?

This sounds like a great idea. For the arbitrage opportunity could be nice to be able to set and receive a notification if the delta goes above a certain threshold
