How to get up to 48% ROI per bet with betting on tennis matches
Learn how to profit from the most accurate sports predictions based on state-of-the-art machine learning algorithms

I know, the headline is pretty catchy, right? But it’s not a fake, as I will later prove to you. I recently launched a web service called sports-ai.dev, which offers sports predictions for football/soccer, basketball, tennis, handball, hockey, volleyball and handball based on machine learning algorithms. If you’re interested in the technical aspects of my web service, please feel free to check out this article I wrote.
Profit accumulated from betting on tennis matches
In the following analysis we are taking a look at the tennis markets from March 1st until April 12th.
Here’s a little example of how you would take a betting decision. Let’s take the match Berretini vs. Harris from the Indian Wells played on the 15th of March. Sports AIs algorithms predicted a probability of 24.33% Harris winning the match. If you transform the probability to an odds format (1/0.2433) you get fair odds of 4.11. 1xBet for example offered a price of 4.36 for a win of Harris, which leads to an edge of approximately 6%. In such a case, it is advisable to bet on this outcome at that price of 4.36 offered by 1xBet.
If you apply this strategy to the period under consideration, then following results would have been achieved.

As you can see in the chart above, the results are very satisfying, even though we struggled with being profitable for the first 200 bets. With a fixed stake of 100€ per bet, 628 bets could have been placed and a profit of approximately 5.000€ could have been accumulated. In the end, with this strategy, a ROI of 7,77% could have been achieved.
Best betting strategy to achieve the highest ROI per bet
The results above show the results with the following strategy: Bets were placed if an edge of at least 3% was found. The higher the edge needs to be in order to place a bet, the higher the ROI will probably be. That is what we saw in our profit report regarding the football/soccer predictions and the same trend is identifiable here too. You can see that there is a positive correlation between the minimum edge of a bet (called threshold on the right side) and the ROI. The downside though, is that the amount of matches meeting the criteria get lower the higher the threshold is set. With a threshold of 14% we achieved a ROI of 48%%!

Which bookmakers to use with Sports AIs tennis predictions?
The following bookmakers were included in the analysis: Bet365, William Hill, Marathon Bet, Unibet, Bet at home, GGBet, bwin, PariBet and 1xBet.The chart below shows how many betting opportunities were found for each bookmaker. The results refer to the strategy where a minimum edge of 3% was used.

The results show that 1xBet is the best bookmaker to use with our strategy when it comes to the amount of betting opportunities. With 191 bets placed at 1xBet, this bookie takes the lead at this statistic followed by MarathonBet with 114 bets. At the end of this statistic we will find bet-at-home with only 5 betting opportunities.
At this point, there is no use in comparing the ROI per bookmaker since the amount of bets varies a lot between bookies. That’s something that can be analyzed in the future.
