Upvote PredictionBell Share ## About PredictionBell PredictionBell is a dashboard that aggregates prediction market data from Polymarket and Kalshi into a single view. It covers live sports markets alongside broader event-driven categories such as equities, crypto, the Fed, macro indicators, earnings, and volatility contracts. The tool is built around research and discovery rather than trading execution, pulling live odds from both venues so users can see how the same event or outcome is being priced across platforms without switching between sites. Beyond basic aggregation, PredictionBell highlights overnight repricing, making it easier to spot how odds shifted while markets were less active, and it surfaces cross-venue gaps where Polymarket and Kalshi diverge on the same question. This positions it as an analytics and arbitrage-discovery tool for anyone trying to compare pricing across markets rather than rely on a single source. Its scope spans both the fast-moving world of live sports contracts and the slower-moving, news-driven markets tied to macroeconomic and financial events, giving it use as a general-purpose lens on prediction market pricing. The service is free to use, with the core value proposition being consolidation: instead of checking Polymarket and Kalshi separately, users get both feeds, sports and non-sports markets, in one dashboard oriented toward spotting pricing differences and market movement.
