About ArbLense
ArbLense is an informational scanner for comparing prediction market prices across Kalshi, Polymarket, and Opinion.
The scanner
Read both sides of a route
Compare route cost and potential profit per contract at top-of-book prices, alongside available depth and resolution timing.
How ArbLense worksThe blog
Understand the context
Read guides to prediction market routes and venue workflows. Articles are dated reading material; prices in an example are not live quotes.
Read the blogInformation for your own decisions
ArbLense does not execute trades or custody funds. You place orders directly with the venues and must check their current terms, eligibility requirements, fees, liquidity, contract wording, and resolution rules.
A displayed price difference is not a guaranteed return. Prices and available depth can change before either side of a route is filled. Read the terms and risk disclaimer before using the scanner.
People and attribution
The author directory identifies contributors with public profiles. Each article carries its own author byline and publication and update dates. A review credit, when present, is separate from authorship.
Our editorial policy explains source expectations, attribution, and how to report a correction.
