How these tools work
Alert tools push a message when something happens on a market or in a wallet: a price crosses a level, a large trade prints, a wallet you follow opens a position, a new market lists. This category also holds the two news products, Prediction News and Adjacent, which publish articles rather than triggers.
For Polymarket the wallet-following bots are plentiful because wallet activity is public on-chain: Polylerts, PolyTracker, Drops Odds and PolyTradeAlerts all do the same core job in Telegram. PolyAlertHub and the Polymarket Alerts app add price, volume and whale triggers. Kalshi has no on-chain trail, so wallet-following does not exist there and none of the tools on this page cover it.
Pick by delivery channel and by whether you need filters. A bot that posts every fill from a busy wallet is noise; size floors and digests are what turn it into a signal.
How to choose
- Decide where alerts must land. Telegram is universal; Discord is PolyAlertHub only; phone push is the Polymarket Alerts app only; webhooks and email are rare.
- Check for a minimum-size filter and a side filter. Polylerts and PolyTradeAlerts have them; PolyTracker and Drops Odds do not.
- Count wallets. Polylerts caps at 15; PolyTradeAlerts charges $12 every 4 weeks per wallet; the others do not publish a cap.
- Treat self-reported win rates as marketing. None of the tools on this page publish an audited track record for their signals.
- Confirm the tool only alerts. Several products in this category also sell wallet-connected trading; the alert side of each is what these pages cover.
Questions about news & alerts tools
What is the best free Polymarket whale alert bot?
For wallets you name, Polylerts (up to 15 wallets, size and side filters) and Drops Odds (DropsTab, no cap stated) are free in Telegram. For threshold alerts across all wallets, PolyAlertHub's free plan and the Polymarket Alerts phone app offer whale alerts above a value you set.
Are there Kalshi price alert tools?
None of the tools in this category cover Kalshi. Kalshi has no public on-chain wallet activity, so wallet-following bots do not exist for it.
Do Polymarket alert bots copy trades?
The tools on this page do not. Polylerts, PolyTracker, Drops Odds and PolyTradeAlerts send notifications only; what you do with them is your decision.
Trackers find the edge. Calculators size it. Alerts time it.
