Prediction markets let people trade contracts that pay out based on whether an event happens. Sizing the industry is harder than it looks, and the reason tells you something about how these markets actually behave.
Explainers
Kalshi's per-contract trading fee follows a price-based formula rather than a flat percentage.
Explainers
Prediction market platforms turn questions about the future into tradable contracts whose prices read like odds. Here is what they are, why they exist, and what remains legally unsettled.
Explainers
The best prediction market apps are the ones whose fee math, settlement rules, and market types fit what you actually want to trade. Here is how to compare them.
Explainers
A step-by-step walk through opening an account and placing a contract on PredictIt and Kalshi, including how settlement works, what the fees cost you, and why the two platforms sit under different rules.
Explainers
The most interesting prediction market contracts are the ones regulators have not clearly claimed. Here is where oversight ends and the gray zone begins.

The two AI labs everyone lumps together are priced completely differently on prediction markets. Anthropic reads as near-certain to list; OpenAI barely registers for 2026. Here is why.
Explainers
Kalshi's valuation swings on regulatory outcomes and volume growth, not just fee revenue. Here is how a federally regulated prediction market gets priced, and why the number is contested.
Explainers
Kalshi and Polymarket let you trade on the outcome of real-world events, but they answer to different rules, live on different rails, and settle in different ways. Here is what separates them.
Explainers
Kalshi runs a CFTC-regulated exchange, so its API carries obligations most crypto prediction markets skip: real accounts, identity checks, and a published fee schedule. Here is what that changes for builders.
Explainers
Polymarket advertises zero trading fees, and that is true. But a $100 trade is rarely free. Here is where the money actually leaks out, with a worked example.
Explainers
Kalshi's trading fee is not flat. It follows a curve that peaks when a contract trades near 50 cents and falls toward both price extremes. Here is what that costs on a real trade.
