Copy-trading tools
All copy-trading botsHaileyWelch fails our checks, but these tools can follow any wallet — start from one that passes.

Rainmaker
AI-agent terminal that unifies arbitrage, copy-trading and analytics across Polymarket, Kalshi and Novig. Its Cloud9 agents snipe arbitrage between venues, score and replicate winning traders, and mine analytics — with a focus on sports markets (NFL, NBA, NCAA).

Whalidate
Verified PartnerCopy trading for Polymarket that starts with the question a profit leaderboard skips: how did the wallet make its money? Its WhaleFinder tool replays each wallet's public history and scores the return on the money put in, the number of settled trades, the worst drawdown and how much of the profit came from a single bet. By default a wallet needs a 15% return, 30 settled trades, a drawdown of 25% or less and no more than half its profit from one trade; on Sep 30, 2026, 166 of the 1,346 wallets scored in full passed. You pick the wallets and set the rules — entry price band, slippage cap, market categories, caps per market and per event, daily, weekly and drawdown loss limits — and Whalidate copies only the new buys that pass, with a fill-or-kill order at the price the book offers. Every strategy runs on paper for free with no time limit. Live copying needs a paid plan from $49 a month, takes no fee per trade, and runs from a trading wallet whose keys Whalidate holds.

PolyWin
Verified PartnerTelegram bot that puts the whole Polymarket workflow in one chat: copy trading, two snipers, backtests and AI trader discovery. Copy Trade mirrors — or counter-trades — any wallet you pick, sized as a fixed USD amount, a percentage of the leader’s stake, or portfolio-weighted so your allocation matches theirs with a 0.01–10× multiplier, under category, price-range, market-volume and daily-spend limits with take-profit and stop-loss on every copied fill. Final Snipe fires a market order the second your entry conditions pass; Reversal Snipe ladders limit orders into an overreaction and cancels unfilled rungs about five seconds before resolution — both across BTC, ETH, SOL, XRP, BNB, DOGE and HYPE on 5m, 15m, 1h and 4h. Every snipe strategy can be backtested against a pre-computed pool of parameter combinations first, returning Most Profitable, Fast and Safest variants. AI Picks re-scores Polymarket traders every six hours, discarding wallets that show wash trading or leaderboard farming. Non-custodial: a Polygon wallet is deployed on first start, keys are encrypted per wallet and exportable, and TOTP 2FA gates withdrawals and key exports. No KYC, and deposits from ten chains auto-bridge to USDC.
