Add-on tools for prediction markets (Polymarket / Kalshi): track public wallets, event alerts, cross-platform odds, subscription. The platforms are booming, but only one new tool is making money
Watching Trackable · a tool that lives in a gap left by big platforms First spotted 2026-11-01 · Last updated 2026-11-03
- Status
- Watching (single sample; upgrades if a second new tool gets into the us Finance Top Grossing top 100)
- Why now, and how long the window lasts
- Kalshi and Polymarket are in a user boom in the US, and the platforms don't themselves offer "see how others are betting"; a solo 60-day app made the Finance Top Grossing top 40. The window depends on whether the platforms build wallet leaderboards and copy-trading alerts themselves, and on state-level US regulation; estimate roughly 12 months (inferred).
- Confidence
- Low (single sample). What would overturn this: Prediction Radar drops out of the us Finance Top Grossing top 100 within 30 days; or Polymarket or Kalshi officially launches wallet leaderboards and copy-trading alerts. What would upgrade it: a second new tool enters the us Finance Top Grossing top 100, or Prediction Radar enters the us overall Top Grossing chart.

The hardest step
Earn user trust without touching regulation. Users expect "copy trades that win," and negative reviews come fast ("a 1-star and a 5-star trader are no different," "cancelled during the trial and still got charged"); platform API fees or bans, and shifting state attitudes toward prediction markets, are all moving targets.
Who it's for
Individual developers who understand on-chain data or the Kalshi API; subscriptions; localization outside the US is still untouched (Polymarket is legal in Europe and Asia, but Curie only charts in the us).
Should every product builder know this?
No.

Prediction Radar's first move into a second major market: es Finance Top Grossing #22 (on the threshold list "first entry into a major-market top grossing chart"), gb #75; us Finance Top Grossing 38→41, rating 1,024. Still a single sample, but it's expanding across language stores. Not upgrading.
