We would like to inform you that Polymarket has updated its platform and changed the way the fee is deducted.

What has changed

Previously, the fee was deducted from the stake amount:
– You bet $100.
– 2% fee = $2.
– The total stake was $98.

Now, the logic is different, and the fee is deducted on top of the stake:
– You bet $100.
– 2% fee = $2.
– The total stake is now $102.

If you do not take the new fee deduction mechanism into account, this will effectively reduce the actual profit from your bets.

We have already adapted the functionality to the new model, and the fee is now calculated correctly in the calculator. The stake amount you need to place on the Polymarket website will be displayed in the additional «Bet» field.

Please ensure that the fee calculation feature is enabled when using Polymarket.

How to enable

The feature is available in the exchange settings:

My account → Exchanges → Polymarket → Commission type = AUTO.

Once enabled, the fee will be calculated automatically.
