Prediction Markets - Simply Explained
Polymarket is the world's largest prediction markets platform. It allows traders to buy and sell contracts on the outcomes of future events - from political elections to economic decisions and sports results.
How Does It Work?
Each market on Polymarket represents a binary (Yes/No) or multiple-choice question. Prices range from $0 to $1 and represent probability:
- $0.70 for "Yes" = The market estimates a 70% chance the event will happen
- $0.30 for "No" = A 30% chance the event won't happen
If the outcome occurs, those holding "Yes" receive $1 per share. Those holding "No" lose their investment.
Why Do Prediction Markets Matter?
Academic research has shown that prediction markets provide more accurate forecasts than traditional polls and experts. The reason: when people put real money on their opinions, they tend to be more honest and do more thorough research.
Prediction markets are the most efficient way humanity has found to aggregate and disseminate information about future events

Last updated: 16 September 2026
What we collect
- E-mail address and display name - provided by you when signing up with a one-time e-mail link, or received from your Google account if you chose "Continue with Google".
- Your preferred interface language, and your training-mode data: virtual balance, virtual positions and training history.
- A sign-in record for security: IP address and browser type (User-Agent) at sign-in, with the session's expiry time.
- A sign-in cookie (poly_token, up to 30 days) and a language-preference cookie (poly_lang_seen). Anonymous usage statistics via Google Analytics 4 (with IP anonymisation) and an internal measurement pixel that stores neither cookies nor IP addresses.
- We do not collect or store passwords. Sign-in is passwordless - a one-time e-mail link or Google.
Signing in with Google and X
- "Continue with Google" uses Google's official OAuth 2.0 / OpenID Connect flow. You enter your Google credentials only on Google's own page (accounts.google.com); this site never receives, sees or stores your Google password.
- The only permissions requested from Google are the basic ones: openid, email, profile - your e-mail address, name and public profile picture. We do not request access to Gmail, contacts, calendar or any other data, and we do not keep Google's access tokens after sign-in. In practice we store only the e-mail address and name.
- The sign-in Redirect URI is https://polymarkets.co.il/api/v1/auth/google/callback only.
- "Continue with X" is not active and is marked "Soon" on the site. No sign-in, permission request or data collection from an X account takes place.
How we use it
- To run your training account, keep your training progress, and show you on the leaderboard - only if you opted in under account settings.
- To send sign-in links by e-mail, and at most one weekly update if you subscribed - with one-click unsubscribe. E-mails are sent through the Mailgun provider.
- To secure the account and prevent abuse. We do not sell or pass personal data to third parties - in particular not to Polymarket or to any service the site links to.
- Data is stored on our own servers in the European Union (Amsterdam) and kept for as long as the account is active.
