Olympus vs Whalidate

What Whalidate does

Copy trading for Polymarket that checks how a wallet made its money before you follow it. Its WhaleFinder replays each wallet's public history and scores the return on the money put in, the settled trades, the worst drawdown and how much of the profit came from one bet; on Sep 30, 2026, 166 of the 1,346 wallets scored in full passed its default checks. You pick the wallets and set the rules — price band, slippage cap, categories, caps and loss limits — and Whalidate copies only the new buys that pass. Paper trading is free with no time limit; live copying is free for 14 days on Starter, then from $49 a month with no fee per trade, either through a session key on your own Polymarket account that can trade but not withdraw, or from a trading wallet whose keys Whalidate holds.

• WhaleFinder: 15,371 leaderboard wallets scored on return, settled trades, worst drawdown, the share of profit from the best trade and the top five, steadiness and edge per trade. 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; the checks can be changed
• Every rejected wallet shows why: profit resting on one trade, too short a record, too many copiers already
• Entry rules per strategy: the whale's stake, a price band, a slippage cap, time to resolution and categories; rules per whale on Pro and Elite
• Caps per market, per event, on total exposure and on the live budget; daily, weekly and drawdown loss limits stop new entries
• The order book is read again just before sending, then one fill-or-kill order goes out; on paid plans a limit order at the whale's price can wait in the book instead, 30 minutes by default. Copies under $5 are skipped

• Read the methodology, not the landing page. The home page's four whale cards, +$910 to +$5,296 over 120 days, are the best four of the 166 passing wallets. They come from a model with no fees or slippage that exits when the whale does, while the product holds each copy until your own exit or resolution. The methodology itself says copying all 166 came to about break-even. Since Nov 1, 2026, paper trades are priced from the live book and charged the taker fee. Paper still cannot show a live order failing, which happened about 3 times in 100 in October by the vendor's count.
• Preset cards are replays, not records, until a preset has 30 settled trades of its own, and on Nov 9, 2026 some cards annualised a few months into tens of thousands of percent a year. Whalidate sent us every trade behind two cards, and we rebuilt both; when we found the whale's own fee inside its prices, it corrected the cards down. Reef's +27% (Dec 2025 to May 2026, was +34%) uses today's wallets, but they were picked on their record through October. Current's +88% (Jul to Oct 2026, was +94%) re-picks wallets each month by rules tuned on those same months, and only 6 of its 196 copies came from today's wallets. Whalidate's own test of 1,036 wallets found that copying every whale buy lost money after costs; our guide “Does Polymarket copy trading work?” has the numbers.
• Live trading runs one of two ways. With your own Polymarket account, you sign a session key that can place and cancel orders but not withdraw. It lasts up to 180 days, and you can revoke it sooner. Your money stays on Polymarket, but a key that trades can still lose it, and the budget and loss limits are Whalidate's rules, not Polymarket's. Only Deposit Wallet accounts used through a wallet app such as MetaMask or Rabby can connect; e-mail and Google sign-ins cannot. The other way is custodial: you deposit USDC into a trading wallet whose key Whalidate holds, and its Risk Disclosure says a breach, a software mistake or a shutdown could delay or lose those funds, with no insurance. The Terms name no company, address or governing law, only a support email.
