CopyOdds

Overview

Copy trading for Polymarket in the browser and as a Telegram Mini App. You pick a wallet from its smart-money board or paste any address, look at the wallet's profit curve, drawdown and a copy backtest that adds delay and slippage, then choose how big each copy is — a fixed amount, a share of your balance, or a size scaled to the wallet's largest past fill — and a slippage limit. CopyOdds then mirrors the wallet's buys and sells from a trading wallet it creates and holds for you. The board and backtests are free; every copied fill, opening or closing, costs 0.5% of its size, paid from prepaid Gas sold from $30. The same account runs an eight-level referral program that pays up to 80% of what the people below you spend.

How it works

• This is a referral pyramid as much as a copy-trading tool, and its own code says so. The open backend sets eight partner levels, L1 to L8, that take 10% to 80% of what the people below them spend on Gas, with the difference passed up as many as eight levels. Your first Gas purchase makes you L1; three direct referrals at L1 lift you to L2, and larger networks unlock the levels above automatically up to L7, while L8 can only be bought. Rank is for sale in the store as well: the $4,250 Elite package holds half the Gas of the $850 package and adds level L4, so about $3,400 of its price buys a place in the referral tree. The landing page leads with “Share. Earn.” and “up to 70% commission” rather than with copy trading. The Terms say rewards come only from fees already earned and that the program does not depend on recruiting; that is true of where the money comes from, but it is still paid for by the Gas that the people you bring in buy.
• Copying is custodial. When you sign up, CopyOdds creates a trading wallet for you; its Terms say you do not hold the private key, and the app says the key cannot be exported because the wallet signs remotely through CopyOdds's own custody service. You deposit USDC on Polygon or BSC, and CopyOdds signs the copied trades, the Gas purchases and your withdrawals, which the Terms say can be held for security reviews or legal holds. The Terms name no company, address or country — disputes fall under “the laws applicable to CopyOdds' operation of the Services” — and their support email is on copyodds.com, a domain with no website and no mail record. Users in the United States and mainland China are barred.
• The code is open apart from the part that holds the money. Two public repositories under Apache-2.0 carry a large, tested TypeScript backend and the web app, including the Gas store and the referral levels, but the service that keeps the keys and signs is not among them. Activity is hard to measure: we did not find CopyOdds among the 589 builders in Polymarket's builders Data API, and its code switches between several builder credentials. The public signals are modest — a Telegram group of 840 members and a channel of 50, an X account with 7,744 followers that itself follows 7,022 — and the domain dates from Mar 20, 2026. The developer works in Chinese, and the site's media sits on Tencent Cloud in Singapore.
• The leaders move fast. On the morning of Oct 16, 2026 the public feed of leader trades was mostly one wallet buying five-minute Up or Down windows at around 89¢, plus Dota 2 and Counter-Strike matches; a copy placed after the leader's fill, at your slippage limit, gets a worse price on exactly these markets, which the backtest's delay only estimates. The wallets we checked are real Polymarket accounts — Starlord2, first in the ranking of CopyOdds users, shows $74,435 of all-time profit on Polymarket's leaderboard — but that ranking was dated Oct 6 when we looked, does not say how much of the profit came from copying, and shows each user's email with the middle masked. We read the site, the Terms, the store and the app's interface text, the open code and the public API (the board, the leader feed and the Gas prices answer without sign-in; account routes ask for it). We did not open an account or deposit, so copying itself is untested by us.
