By joining the platform and selecting the welcome bonus during registration, players can receive a 100% deposit match worth up to $250. This exclusive offer is designed to give newcomers a powerful start, allowing them to explore a wide range of live sports markets with extra funds at their disposal.
To participate, new users must select the welcome bonus option while filling out the registration form. After creating an account, the first deposit must be made by 20:59 GMT on 31 December 2025. A minimum deposit of $5 is required to qualify, and the amount of the bonus will equal 100% of that first deposit, up to a maximum of $250. Once credited, the bonus funds will appear in the customer’s Bonus Balance, where they can be used for betting immediately after activation.
The promotion runs from 09:00 GMT on 6 December 2024 until 20:59 GMT on 31 December 2025. During this time, all new customers who meet the qualifying criteria can take part. The offer applies only to first-time depositors, and each player may claim the welcome bonus once. The terms are straightforward: make the initial deposit, receive an equivalent bonus amount, and then meet the wagering conditions to unlock the funds for withdrawal.
In order to transfer the bonus funds from the Bonus Balance to the main balance, players must complete a turnover requirement. The combined amount of the initial deposit and the bonus must be wagered five times on qualifying live bets. These live, or in-play, bets must have minimum odds of 1.50 to count toward the rollover total. All qualifying bets must be placed and settled within 14 days of the first deposit. Bets placed outside this window or at lower odds will not count toward fulfilling the conditions.
To illustrate how the turnover requirement works, consider two examples. If a player makes a first deposit of $25, they will receive a $25 bonus. To transfer this $25 bonus into the main balance, they will need to place qualifying live bets totalling at least $250 (that is, five times the combined amount of the $25 deposit and $25 bonus). If a player deposits $250 or more, they will receive the maximum possible bonus of $250. In this case, the combined amount of $500 must be turned over five times, requiring qualifying bets totalling $2,500 before the funds can be released.
The Bonus Balance functions as a supplementary bankroll. When the main balance is insufficient, bonus funds will automatically be used for betting and will still count toward the turnover requirements. Any winnings generated from bets placed with bonus funds will be credited to the Bonus Balance as well. Once the wagering requirement has been met in full, those winnings will be transferred from the Bonus Balance to the main balance within 48 hours. At that point, the funds become available for further betting or withdrawal, subject to normal account conditions.
The maximum amount that can be transferred from the Bonus Balance to the main balance is limited to 100% of the qualifying deposit, up to $250. This ensures that the welcome bonus remains a true one-to-one match of the player’s first deposit. If at any point a withdrawal is made before completing the turnover requirement, and the remaining amount in the main balance falls below the original deposit total, the bonus and associated winnings will be voided.
Only live (in-play) sports bets at minimum odds of 1.50 qualify for this promotion. Customers may choose from any available live sports market on the website. For single bets, the individual odds must meet or exceed 1.50. In doubles, trebles, or accumulator bets, the combined odds must be at least 1.50, while for multiple-line bets, each selection must independently meet the minimum odds requirement. If a match is postponed or a result is voided, and the bet no longer satisfies the qualifying criteria, that bet will not count toward the rollover total, though it will still stand and settle according to its terms.
All bets placed as live wagers—meaning bets placed while the event is taking place in real time—are eligible, regardless of the section of the site where they are found. Whether the qualifying bet wins or loses, the stake amount will count toward the total wagering requirement. This means that every live bet contributes toward unlocking the bonus, offering flexibility and transparency for the player.
It is important that players complete the turnover requirement within 14 days of their first deposit. Failure to do so will result in the bonus being voided, and any remaining bonus funds will be forfeited. Similarly, certain types of bets and products are excluded from this promotion. Bets placed on Casino, Live Casino, Toto, or any non-Sportsbook product will not count as qualifying bets. Cashed-out bets, edited bets (using the “Edit Bet” feature), or wagers made with Free Bets will also be excluded. In addition, voided bets do not contribute toward the turnover calculation.

In summary, the Marathonbet welcome bonus offers new players a simple yet generous way to double their starting bankroll. By depositing a minimum of $5 and placing live bets at odds of 1.50 or higher, newcomers can turn their initial stake into a rewarding betting experience worth up to $250 in extra funds. Meeting the five-times rollover requirement within 14 days is key to unlocking the full value of the promotion, after which winnings become fully withdrawable. With transparent conditions and flexible betting options, this promotion provides an ideal introduction to Marathonbet’s live sports markets, giving every new player a strong start and a fair chance to build their balance responsibly.
