Prediction markets move fast. A single whale trade can shift a market by double digits in seconds. A key political event can flip odds overnight. By the time you manually open Polymarket and scroll to the market you care about, the opportunity is already gone.

That’s why we built Polymarket Alerts — a free mobile app that delivers instant push notifications for the activity that matters most to you on Polymarket. No account needed, no personal data collected, set up in seconds.

Here’s everything you can do with it.

Market Price Alerts

Set a target price or percentage change on any Polymarket market. When the price crosses your threshold, you get a push notification immediately.

  • Target price alerts — get notified when a market hits a specific price (e.g., “Alert me when Yes hits 70¢”)
  • Percentage change alerts — track sudden moves (e.g., “Alert me if this market swings 10% in either direction”)
  • One-tap setup — find any market, set your number, done

No more refreshing pages. No more staring at charts. Set it once and let the app watch for you.

User Activity Tracking

Follow specific Polymarket wallets or usernames and get notified in real time when they trade.

  • Trade notifications — know instantly when a user buys or sells a position
  • Comment tracking — stay updated when followed users post comments on markets
  • Unlimited follows — track as many users as you want

This is especially useful for following well-known traders, political insiders, or anyone whose Polymarket activity you find informative.

Whale Alerts

Large trades often signal that someone knows something — or at least has strong conviction. Whale Alerts let you define your own dollar threshold, and the app notifies you whenever a single trade exceeds it.

  • Custom thresholds — set what counts as a “whale” trade for you ($1K, $10K, $100K — your call)
  • Instant notifications — know within seconds when a massive position is opened
  • Market context — see which market the trade happened in and which direction

Whale movements are one of the strongest signals in prediction markets. Don’t miss them.

Insider Trader Detection

One of the most unique features in Polymarket Alerts. The app analyzes trading patterns and flags activity that resembles insider trading.

Detection types

  • Timing-based — traders who consistently enter positions right before major outcomes
  • Profit-pattern — accounts with statistically improbable win rates across resolved markets
  • Volume-based — unusual position sizes from accounts with short trading histories

The most common insider pattern: a new account appears, places one large trade on a specific outcome, and that outcome resolves within days. Our system flags these patterns automatically.

Category filters

You can filter insider alerts by market category — politics, crypto, sports, science, and more — so you only see the activity relevant to your interests.

Watchlist

Organize the markets and users you care about in one place. Your watchlist gives you a quick overview of current prices and recent activity without digging through Polymarket’s interface.

Timeline

Track how your watched markets resolve over time. The timeline shows you a history of outcomes, helping you spot patterns and review past predictions.

Disputes

Polymarket markets occasionally enter a dispute phase where the initial resolution is challenged. Dispute alerts notify you when this happens, giving you time to react before a market re-resolves — which can cause major price swings.

Built for Speed and Privacy

We designed Polymarket Alerts around two principles: fast and private.

  • No account required — open the app and start creating alerts immediately
  • No personal data collected — we don’t ask for your name, email, or anything else
  • No data selling — your alert preferences stay on our servers and nowhere else
  • Dark & light themes — use whichever you prefer
  • Lightweight — the app is small, fast, and doesn’t drain your battery

Available on iOS and Android

Polymarket Alerts is completely free and available on both platforms:
