AI Analysis

●●SolidSolve My ProblemDark HorseSlick

Cross-exchange prediction market data without scrolling six platforms; arbitrage finder included.

Strengths

•Solves a real aggregation pain: traders currently check Polymarket, Kalshi, and others in isolation.
•Arbitrage finder and probability normalization across exchanges add utility beyond raw data pulls.
•Clean, dark-themed UI makes heavy data (50K+ historical markets) navigable and scannable.

Weaknesses

•API aggregation of existing platforms; no proprietary data, novel methodology, or predictive edge.
•Early-stage with acknowledged bugs; filtering and region-tagging still experimental.

Post Description

I’ve been following prediction markets for a while, mostly around elections and international tensions. One thing that kept bugging me is the data is kind of scattered across platforms and it’s hard to compare things side by side.

So I built PoliticaHub to pull some of it together.

Right now it aggregates markets from Polymarket and Kalshi and shows the implied probabilities for things like election outcomes, conflict escalation, recession odds and similar stuff. The idea is basically just to see what traders are pricing in across different events.

Under the hood it just pulls data from their APIs, normalizes the probabilities and refreshes every few minutes. Nothing super fancy. I’m still experimenting with things like filtering by region or event type and maybe highlighting big probability swings.

Its still pretty early and im sure there are bugs or weird things I havent noticed yet. Would appreciate any feedback from the HN crowd, especially if something looks broken or confusing.
