What is PredictionHero?

The table brings chance, price, liquidity, volume and time remaining into one discovery view. Expand a group to see its constituent markets and filter by exchange, category or expiry. Coverage includes Polymarket, Kalshi, Opinion and Limitless alongside other venues.

Trending, breaking, new and ending-soon modes offer different research horizons. Account watchlists, thematic aggregates such as the War Index, and explanatory Insights add monitoring and reading paths. Source links take users to venues, so the interface should not be treated as evidence of in-app execution.

Who it is for

For researchers comparing venue coverage or looking for newly listed and soon-to-resolve questions.
For readers monitoring a theme who are willing to inspect the events and methodology behind an index.

Workflows with PredictionHero

Compare the underlying contracts

Search a question, expand its group and compare liquidity, expiry and venue links before reading each source market’s rules.

Monitor an index theme

Open a thematic index and inspect both its constituent events and its methodology before interpreting the headline value.

Research a near deadline

Combine ending-soon and category filters, then check the venue’s source rules and settlement timing.

Pricing and total cost

Public discovery and editorial pages can be browsed. Account features use signup and login; the reviewed interface lists no subscription price.

Getting started

Before you start: Read an index’s own methodology; a headline aggregate is not interchangeable with every underlying contract probability.

Search a question or choose a category, then set exchange and expiry filters.
Expand a matched event and compare its contracts and source rules.
Create an account if you want saved-event features.

Contracts grouped under one question can differ in definition, outcome and settlement time.

Our take on PredictionHero

Matched groups, liquidity filters and thematic views make broad discovery useful. Headline probabilities still need a contract-level reading because definitions and index construction can differ.
