Today's tennis predictions

Welcome to AcesTips, your home for free tennis predictions, available in several languages for fans who follow the tour worldwide. Today is August 20, 2026 and on this page you'll find our previews for today's and tomorrow's matches — 17 matches analysed right now — updated every day across the entire international calendar: from the Grand Slams to the Masters 1000, from the ATP and WTA 500 and 250 events down to the Challenger and ITF circuits.

A prediction is not a promise of winning: it's a probability estimate built with method. That is exactly what AcesTips gives you, a clear analysis to reason with. In this guide we explain how our previews are made and, above all, how to read them and get the most out of them so you can follow tennis with more insight.

How to recognise a reliable prediction

The first step is understanding when a preview truly makes sense. Take a concrete example: Carlos Alcaraz against Jack Draper on the clay of Roland Garros, with the Spaniard a clear favourite. In a context like that, the solid prediction is the one that backs Alcaraz's edge. If instead a preview has the Briton winning with great ease, an alarm bell should ring: it's probably leaning on a feeling rather than the data.

A reliable prediction always starts from the comparison between the real probability of an outcome and how likely the market considers it. That balance is what AcesTips analyses for every match before pointing you to the most sensible outcome. You can check the consistency of our work in the historical results record, where we publish every prediction and how it turned out.

How to get the most out of AcesTips predictions

Receiving a preview is easy. Using it well is what makes the difference. Here's how to get the most from AcesTips predictions.

Follow us every day, not just at the big events

We publish previews every day of the year. A prediction's value isn't only in the Grand Slam finals: often the most interesting opportunities come at the ATP and WTA 250s or in the Challengers, where public attention is lower. Checking the page consistently lets you catch these situations instead of sticking to the most famous matches.

Always read the context, not just the outcome

Every preview is built from an analysis of form, surface and head-to-head. Before following it, spend a minute on that information: understanding why we point to a certain outcome makes you a more aware reader and helps you judge how well that prediction fits what you're looking for.

Combine the prediction with your own knowledge

Know a player or a tournament well? Use our preview as a starting point and enrich it with what you know. AcesTips gives you the statistical picture and the experts' reading; your feel for the individual match completes the reasoning. The best predictions come from this dialogue between data and a personal eye.

Update your assessment at the last minute

In tennis a physical niggle or the weather changes everything. That's why it pays to review the situation as close as possible to the start: we update previews when relevant news emerges, and you do well to keep an eye on the latest before deciding.

Think over the medium term

A single preview may miss the mark: that's the nature of the sport. The right way to judge predictions is to look at consistency over time, not the result of one match. AcesTips works to give you solid, repeatable previews across the whole season.

The factors behind every AcesTips prediction

These are the elements our experts analyse for every match. They're the same ones you can use to read a preview better.

Player level and physical condition

Technical quality is the most obvious starting point. A high-profile player, even below their best, starts ahead of a lower-ranked opponent. But physical condition matters as much as talent, especially in the men's best-of-five Grand Slams, where stamina over the distance is decisive. A recent injury or a crowded schedule can bring even the most solid favourite back to the pack.

Motivation and momentum

Motivation is hard to measure but it shifts the balance. Playing at home — think of the roar behind the Brits at Wimbledon or the American crowds at the US Open — chasing big ranking points or defending a title sparks performances beyond pure technique. Likewise, a player on a losing run struggles to break out of it, while someone in a good moment plays with a confidence you can see on court.

Surface and playing style

The same player can look different depending on the court. A clay specialist builds the point patiently from the baseline; a big server like Taylor Fritz or a shotmaker like Ben Shelton finds fast hard courts ideal. The clash of styles matters too: a devastating serve troubles half the tour on quick surfaces, and it's common for a lower-ranked player to beat a more fancied opponent simply because their game is awkward to face.

Head-to-head and previous meetings

The record of direct meetings says a lot. If a player has already beaten a certain opponent several times on the same surface, that's a signal that weighs in our analysis. But be careful not to stop at the raw number: someone who used to lose consistently may have improved and reversed the trend.

Which tournaments we focus on

The level of unpredictability changes a lot depending on the competition, and that shapes the nature of our predictions.

• Grand Slams (Australian Open, Roland Garros, Wimbledon, US Open): the four most prestigious events, best-of-five sets for the men. Peak preparation from the athletes and, as a rule, fewer surprises in the early rounds.
• ATP Masters 1000 and WTA 1000 (Indian Wells, Miami, Monte-Carlo, Madrid, Rome, Cincinnati, Paris): just below the Slams in importance, with very high-quality draws.
• ATP and WTA 500 and 250: more numerous and less in the spotlight, they're the ground where surprises sprout, because some big names skip them and outsiders arrive highly motivated.
• Challenger and ITF: the lower circuits. They offer plenty of matches every day and are perfect for those who enjoy discovering emerging talent, even if the available data is more limited.
• Olympics, Davis Cup and Billie Jean King Cup: competitions with a particular format, where national pride makes matches less predictable than usual.

The impact of the surface

The surface is one of the most underrated factors for those starting to follow tennis, yet it can flip a prediction. You could almost say that playing on clay or on grass are two different sports.

Clay is slow and rewards players who build the point with long baseline rallies. Grass is fast and slippery, favouring the serve and short points. The hard court, the most common surface through the year, is quick and suits those who hit big and play aggressively. The grass and clay seasons are concentrated in specific periods, while hard-court tournaments run across almost the whole calendar.

That's why, before pointing to an outcome, we always check each player's record on the surface in play. A clay specialist can be vulnerable on grass, and ignoring that would mean basing the prediction on half the picture.

Men's and women's tennis predictions: what changes

The factors aren't identical across the two circuits. In men's tennis, over the five-set distance at the Slams, stamina and depth of game weigh heavily. On the women's tour, best-of-three, serve power, return speed and handling the pressure moments matter more. The balance at the top of the WTA ranking also makes matches often more open, with champions of very different styles like Aryna Sabalenka, Iga Świątek and the American Coco Gauff, while Britain's Emma Raducanu and Katie Boulter keep home fans engaged. AcesTips covers both circuits with the same care, because the interesting opportunities are found among the men and the women alike.

Key rules: what to know to understand tennis better

1. Match format: usually best-of-three sets; best-of-five at the men's Slams. Each set needs at least six games won with a two-game margin (6-4, 7-5). At 6-6 a tie-break is played.
2. The serve: one of the decisive shots. The server starts with an advantage in the game, and holding serve is the basis of any analysis.
3. Scoring: points follow the sequence 15, 30, 40 and game. At 40-40 (deuce) two consecutive points are needed to close it out.
4. The surfaces: hard, clay and grass, each with a different pace and bounce that reward different playing styles.
