PredCopy helps traders make smarter prediction market decisions by tracking and copying the most successful Polymarket whales. We believe that the collective intelligence of top traders can inform better decision-making for everyone. Our platform makes it easy to identify high-performing traders, monitor their positions in real time, and optionally mirror their trades automatically.
PredCopy continuously monitors Polymarket for high-value wallets making significant trades. Once you add a whale wallet to your watchlist, we track their activity around the clock and display their positions, trade history, and performance metrics in your dashboard.
With a Pro subscription, you can enable automatic copy-trading. When a tracked whale opens or closes a position, PredCopy executes a proportional trade on your behalf using your own Polymarket account. You stay in full control — set your own bet sizing, exposure limits, and which wallets to copy.
We source data directly from the Polymarket Data API and Gamma API to ensure accuracy and timeliness. Our engine polls for new trades every 30 seconds, deduplicates transactions, and processes them through a risk management pipeline before executing any copy trades.
Whale identification is based on on-chain trading activity — wallets with significant volume and consistent performance across prediction markets. Our leaderboards rank traders by ROI, volume, and win rate so you can choose who to follow based on transparent, verifiable data.
PredCopy is built with security and reliability at its core. Your Polymarket API credentials are encrypted with AES-256-GCM before storage — we never store plaintext keys. The platform is fully non-custodial: we never hold your funds, and all trades execute directly through your own Polymarket account.
Our copy-trading engine runs as an independent process with built-in risk management including bet sizing limits, maximum exposure caps, stale position detection, and bid collapse protection.
Prediction market trading involves substantial risk of loss. Past performance of any trader does not guarantee future results. The information provided on PredCopy is for informational purposes only and should not be considered financial, investment, or trading advice.
Copy-trading carries additional risks. Whale traders can change strategies, take losses, or exit positions without notice. You should only trade with funds you can afford to lose and carefully evaluate the risks before enabling automatic copy-trading.
