How We Rate and Review Prediction Market Platforms

Every score published on this site comes from one weighted scorecard, applied with real money on a real account and verified by a second reviewer. This page documents the full process — what gets a platform listed, how each criterion is tested, and what happens when a platform falls short.

How we make money: some outbound links on this site are affiliate links. Commissions never influence scores or ranking order — this page explains the safeguards that keep the two separate. 18+.

Before a platform enters testing at all, it must clear four non-negotiable gates. Placeholder copy expanding on each gate in a neutral, documentary register.

  • Valid licence or registration with a recognised supervisor, verifiable in a public register.
  • Segregated customer funds or an equivalent documented protection arrangement.
  • Published terms and fee schedule that we can quote verbatim in our reviews.
  • Working limit-setting and self-exclusion tools available to every account holder.

No pay-to-play

Operators cannot pay to be listed, cannot pay for a higher position, and are not shown drafts before publication. Placeholder sentence on how commercial and editorial teams are separated.

Our step-by-step rating process

ILLUSTRATION: review checklist and magnifier (key: methodology-checklist)
  1. Register and verify a real account

    Placeholder: we sign up as an ordinary user, complete identity checks and time every stage.

  2. Deposit our own funds

    Placeholder: a standard test budget is deposited with the platform's most common payment method.

  3. Trade across three market categories

    Placeholder: identical test orders in sports, politics and economics markets; spreads and fills are logged.

  4. Test support, limits and tools

    Placeholder: support contacted with real questions; deposit limits and self-exclusion configured and confirmed.

  5. Withdraw everything

    Placeholder: a full withdrawal is requested and timed against the operator's stated window.

  6. Score, fact-check, publish

    Placeholder: the reviewer scores the scorecard; a second reviewer re-checks every figure before publication.

SHIELD ILLUSTRATION (key: regulation-shield)

The heaviest-weighted criterion. Placeholder paragraphs describing what we verify: the supervising authority and licence reference, where customer funds are held, how outcome disputes are resolved, account-security features such as two-factor authentication, and the operator's complaint history.

Placeholder note: we re-check register entries at every quarterly re-test and after any reported licence change. A platform that loses its licence is removed the same day we confirm it.

Markets, liquidity and trading experience

Placeholder explanation of how category breadth is counted, how order-book depth is sampled on the five most-traded markets during one fixed week, and how we judge the clarity of the order ticket — price, implied probability and depth shown before confirmation.

Welcome offers and promotions

Offers are scored on transparency, not size. Placeholder copy: a modest offer with clear conditions outscores a large headline number with restrictive small print. We read the full published terms, register fresh test accounts when an offer changes, and quote conditions verbatim in our offer directory.

We never present an offer as "free money". Every offer summary on this site states the minimum deposit, turnover requirement, eligible markets and expiry window next to the headline figure. 18+.

Payments, fees and money handling

Placeholder description: we deposit and withdraw real funds with each supported method, record the time from request to arrival, and compare every charge against the published schedule. Undisclosed fees are treated as a serious finding and flagged in the review.

  • Deposit methods, minimums and crediting times — tested, not copied from marketing.
  • Withdrawal speed measured end to end, including identity-check delays.
  • Fee schedule cross-checked line by line against what our account was charged.

Customer care

Placeholder method note: we contact support through every advertised channel with a beginner question, a payments question and a responsible-gambling question, and grade response time, accuracy and tone. Channels, hours and our measured response times appear in each review.

Mobile apps

Placeholder method note: reviews cover the iOS, Android and web versions separately where they differ — onboarding, order ticket usability, price alerts, accessibility settings and feature parity with desktop. Screenshots in reviews come from our own test accounts.

APP CHECK

Onboarding

Placeholder: registration and verification completed on-device.

APP CHECK

Order ticket

Placeholder: price, probability and fees visible before confirming.

APP CHECK

Safer-play tools

Placeholder: limits and self-exclusion reachable within the app.

What happens when a platform isn't up to scratch

Placeholder policy statement: platforms that fail a gate criterion are not listed at all; platforms that score poorly are listed with their low score and a clear explanation, because a documented warning is more useful to readers than silence. Scores are re-assessed quarterly and after any major fee or rule change.

A high score is not a recommendation to trade

Our ratings compare platforms; they say nothing about whether event trading is right for you. Real money is at risk on every platform listed, however well it scores.
