I See an 'Insufficient Allowance' Error
What the insufficient allowance error means on Polycopy: Polymarket's current exchange needs its own one-time approval, and how to grant it from your Polymarket portfolio.
Last updated August 21, 2026
This error usually means your Polymarket account needs a one-time approval it has not given yet. Polymarket's current exchange needs its own approval, separate from any approval you granted its earlier version. Granting it takes a minute on polymarket.com, and after that trading works everywhere, including through Polycopy.
What the approval actually is
An approval, sometimes called an allowance, is permission you grant on Polymarket for its exchange to move your pUSD when your orders fill. Polycopy never holds your funds, so the approval sits between your wallet and Polymarket. That is why the fix happens on polymarket.com rather than inside Polycopy.
Why approving once wasn't enough
Polymarket has run more than one version of its exchange, and each version needs its own approval. If you approved a long time ago, that approval likely covers the old exchange, not the current one. Your funds are fine. The current exchange just has no permission to trade them yet.
How to fix it
Open your Polymarket portfolio
Go to polymarket.com/portfolio and sign in with the account you use with Polycopy.
Complete any "Enable trading" prompt
If Polymarket shows an Enable trading prompt, complete it. That grants the one-time approval for the current exchange.
Retry your trade on Polycopy
Come back and try the trade again. It goes through once the approval is in place.
Nothing to enable? Contact support
If no prompt appears, the error can be transient state on our side rather than a real allowance problem. Use the Get Help form (the ? icon in the top navigation) and we will check it from our end.
