Matchbook employs a unique commission structure for its tennis betting, where it typically charges a commission based on the net losses of its users during a specific betting period. This means bettors only pay a commission on their losses, rather than on the total amount staked, which can be more favorable for users. The standard commission rate can vary but often ranges from 1-2% depending on the specifics of the market and user agreement. Users should also note the terms and conditions, which may include details on the calculation of net losses, any applicable minimums or maximums on commissions, and potential promotional offers that could affect rates. It's crucial to read the latest terms directly on Matchbook's website or customer support resources for the most accurate and updated information.
