Tennis Futures Bets: Grand Slam Winners in 2025

Nothing beats winning a Grand Slam in professional tennis. The only thing that comes close might be correctly predicting which men’s or women’s player will do so at top online sportsbooks.

You can win a bunch of cash if you can predict the Grand Slam winners in 2025, and my goal is to help point you to the likely winners. A lot goes into betting on Grand Slams, of course, as recent form, odds, seeding, opponent history, event history, and health all roll into one tough to predict ball of mayhem.

Seriously, you can have everything right, but if an injury pops up, or poor seeding sets up a less than ideal second or third round matchup for a favorite, your perfect pick can go up in flames in a hurry.

That said, even this far out, there is value in eyeing the 2025 Grand Slam tennis champions. Some will be familiar names – and for good reason – while others could be interesting values that are worth our time.

Join me as I predict the 2025 Grand Slam winners for both men’s and women’s tennis.

What is a Grand Slam in Tennis? 

A Grand Slam refers to a professional tennis player winning all four Grand Slam titles in a calendar year. These are all grand slam events individually, but the feat is more impressive if a specific individual can “sweep” the key tournaments in one season.

These key grand slam events include the Australian Open, the French Open, Wimbledon, and the US Open. 

The Australian Open is held in Melbourne, Australia every January and played on hard courts. The French Open is held in Paris, France and is the only grand slam event played on clay courts.

Wimbledon is played in London, England over the course of June and July, and is played on grass courts. Finally, the US Open is typically in New York, USA between August and September and is played on hard courts.

2025 Tennis Grand Slam Schedule

Ready to bet on who will win each tennis grand slam in 2025? First, check out the official schedule for the coming season.

• 2025 Australian Open (Melbourne, Australia) – Jan 13th-Jan 20th
• 2025 French Open (Paris, France) – May 26th-June 2nd
• 2025 Wimbledon (London, England) – June 30th-July 7th
• 2025 US Open (New York, USA) – August 25th-September 1st

The new season started off the right way with a massive grand slam in Australia. Whoever wins that for either the men’s or women’s side will officially be on Grand Slam watch, and will be among the top contenders to win the French Open.

The second grand slam of the year comes way later in May, so there is a mild layoff and plenty of other tournaments to bet on before we get there.

The 2025 tennis season wraps up pretty quickly after that when looking at it from a high level, with the last two grand slams completed within a two month stretch.

2024 Tennis Grand Slams Winners

Sometimes the quickest way to a successful grand slam bet is simply looking at past results. Tennis champions don’t always repeat in back-to-back seasons, but here’s a look at last year’s winner for each grand slam:

It was all Jannik Sinner and Carlos Alcaraz for the men’s side in 2024. Sinner started 2024 off with a bang by snagging the Australian Open, and while he missed the mark in the next two grand slams, he capped the season off with his second grand slam of the year.

Carlos Alcaraz dominated in between Sinner’s wins, as he fended off the great Novak Djokovic at Wimbledon to win his second grand slam of 2024. Prior to that, he took down first place at the French Open.

For the women’s side, Aryna Sabalenka was the most dominant force. She followed Sinner’s path in starting off 1-0 in 2024, and then won her second grand slam of the season at the US Open.

Men’s Tennis Grand Slam Winners For 2025

Okay, so who will win the tennis grand slams in 2025? History tells us a lot, but at some point you need to read the signs and make some predictions.

Here are three guys from the men’s side I’ll be eyeing for big wins this year.

Jannik Sinner (-375)

Sinner was a force with two grand slam wins last year, and it feels like the 23-year old is just scratching the surface of how good he can be. Of course, he will have to navigate new territory, seeing that he was involved in a controversial doping scandal.

The present #1 ranked men’s tennis player, Sinner should have a fantastic chance to add to his hardware, as he’ll be a viable contender in virtually every tournament he competes in.

He has yet to advance past the Semifinals at the French Open or Wimbledon, but I wouldn’t be shocked to see him find more success (and even win it all) at one of those tourneys. That said, in his young career, he only has one tourney title on clay, so I’d lean toward a Wimbledon victory.

What’s more likely, however, is a title defense. Most tennis betting sites peg Sinner as the 2025 Australian Open favorite, and I have a hard time fighting the logic. I think he could open the year up with another win here, and instantly be thrust in the grand slam conversation.

Even if he doesn’t, however, he’d again be a strong candidate to win the US Open, and he’d be live to win any grand slams in 2025.

Bet: Yes (-375)

Carlos Alcaraz (-450)

Much like Sinner, I don’t see much reason to shy away from Alcaraz. He might be even more fun to bet on, though, as he’s even younger at 21, but has already been far more successful in grand slam tournaments.

Alcaraz won two of them last year, but he also won Wimbledon in 2023 and secured a men’s US Open title the year prior in 2022. That makes three different grand slams for the Spaniard, and at least one grand slam tourney title won in each of the last three seasons.

Alcaraz has been a bit more dominant than Sinner, and he’s also displayed the ability to win on clay. At this point, the only grand slam event he hasn’t won is the Australian Open. He could do the funniest thing ever by winning the 2025 Australian Open and instantly thrust himself in the running for a grand slam sweep.

I doubt that happens, but he’s a very real threat for all four grand slams this year, with Wimbledon standing out the best pick since he’s won there in each of the last two years.

Bet: Yes (-450)

Novak Djokovic (-140)

Lastly, let’s not write off the legendary Novak Djokovic just yet. At 37, he isn’t quite dust just yet, and he did reach the final at Wimbledon last year. Moreover, he reminded everyone who was boss in men’s Olympic tennis by winning gold in Paris last summer,

It’s worth noting that the competition is getting younger and faster, of course, but he’s still spry and skilled enough to hang with the best of them. Novak knows all of these events better than anyone, too, seeing as he’s claimed titles in each of them.

Djokovic is always going to be a tough out, no matter the grand slam. He’s secured three French Open championships, four US Open titles, seven Wimbledon wins, and an insane 10 titles at the Australian Open.

His success at the Australian Open has me eyeing the first grand slam of the year for a possible upset. I think he’s a fun contender at +400 there, while he could be a solid bet at Wimbledon, too. Regardless, he has more experience and titles than anyone going, so he will be live for the upset no matter what.

Bet: Yes (-140)

Women’s Tennis Grand Slam Winners For 2025

Things tend to be a little less predictable on the women’s side. Let’s see which ladies are the best bets to secure a grand slam in 2025 – and which titles they’re likely to snag.

Aryna Sabalenka (-260)

This one feels like a fairly easy call, seeing as Aryna was dominant with two grand slam wins in 2024. Those weren’t her first grand slam wins, either, as she also won the Australian Open in 2023. That gives the 26-year old two wins in that tourney and three grand slams overall.

She has reached the semifinals in both the women’s Wimbledon and French Open, too, so it isn’t crazy to think she could push the envelope in different grand slam events. First up, of course, is the 2025 Australian Open, where she’s among the most likely picks to win again.

That’d give her a third consecutive championship there. That is where I’d predict her grand slam win for 2025 to come from, but I wouldn’t rule out a second title elsewhere. 

Bet: Yes (-260)

Iga Swiatek (-375)

Swiatek feels like an even safer bet to secure at least one grand slam win in 2025. She won the French Open last year, but she’s a lot more accomplished than Sabalenka, especially when you consider that she is just 23 years old.

Swiatek is in good form coming into a new season, as she secured a bronze medal at the Paris Games, and will be looking to get off to a hot start. That isn’t impossible, as she did make it to the semifinals at the Australian Open in 2022.

Of course, due to Sabalenka’s presence, that might not be the tourney I actually bet on Swiatek to win. Rather, I’d focus on the French Open or the women’s US Open – both of which she’s won. The lean is hard toward Roland Garros, though, seeing as she’s racked up four titles there at this point.

Swiatek has a clear edge on clay courts, and she should roll into the 2025 French Open as the favorite or come very close to it. I wouldn’t put Wimbledon or another US Open title out of reach, but I think banking on another French Open title makes her a fine bet overall this year.

That said, keep in mind she’s yet another big name that has been involved in doping scandals, and she already served a one-month ban.

Bet: Yes (-375)

Jasmine Paolini (+1100)

I could take it easy and look at solid players like Barbora Krejccikova or even Coco Gauff, but I like the price on Jasmine Paolini.

The 26-year old came awfully close to scoring a grand slam last year, finishing as runner-up in both the French Open and at Wimbledon. Obviously that doesn’t guarantee she even reaches the final for even a single grand slam, but I know positive momentum when I see it.

She’s been in strong form, as she won the gold medal in doubles at the 2024 Paris Olympics, and helped the Italian squad win the 2024 Billie Jean King Cup. Could she use this momentum as he approaches a brand new tennis tour? It’s not the likeliest of bets, but at +1100, I don’t mind swinging for the fences.

Paolini is presently the #1 ranked Italian tennis player and it’s quite arguable she has finally hit her stride. If she can continue playing as she has been, it’s conceivable that she can again advance to a final and potentially finish the job. 

Bet: Yes (+1100)

Who Has The Most Grand Slams In Tennis?

If you’re betting on grand slams, it might pay to know some history. Here’s a quick look at who has racked up the most grand slams in tennis for both the men and women.

Most Grand Slams In Tennis Women

Margaret Court still stands in with the most grand slams in women’s tennis history, and she was the first to ever win all four in the same year (1953). Court even managed to do that again (1970), and she’s still the only female tennis player to accomplish the feat twice.

She won each of the four grand slam tournaments at least twice, with most of her dominance presiding over the Australian Open.

Serena Williams is a little more well known these days, as the somewhat recently retired phenom has the most titles in the Open era. She’s regarded by many as the best female athlete of all-time, and arguably women’s greatest tennis champion.

Steffi Graf isn’t far behind these ladies, of course. She originally set the bar in the Open era and ranks third with 22 grand slam singles titles. She also is the only female tennis player to hold the Golden Slam, which is winning all four grand slams and securing an Olympic gold medal in the same year.

Most Australian Open Wins

Margaret Court leads all women with 11 wins at the Australian Open. She dominated at this event and the next closest player was Serena Williams with 7 titles.

Most French Open Wins

Chris Evert cracked the top-5 in grand slam titles and a big reason why is her dominance at the French Open. Her hold over this event might not last forever, as she won seven titles here, but is only three ahead of Iga Swiatek (4) who is still obviously very much active.

Steffir Graf sits behind her with six and Margaret Court had five wins at this prestigious clay court event.

Most Wimbledon Wins

Martina Navratilova was incredibly dominant at Wimbledon and her 9 career wins still lead the way for all women. She actually tied for most overall wins to make it into the top 5 technically, but most of her damage was done here.

Right behind her is Helen Wills (8), while Steffi Graf and Serena Williams both notched seven wins at Wimbledon over the years.

Most US Open Wins

Molla Mallory had an impressive 8 US Open titles, which still stands as the most for that grand slam. Helen Willis is in second with seven wins, while Chris Evert and Serena Williams (six a piece) rank third.

Most Men’s Tennis Grand Slams

If you’ve followed men’s tennis over the past three decades, you’ve enjoyed the golden era in terms of grand slam dominance. Sure, there are other tennis greats, but none come close in terms of sheer dominance at the biggest events.

Nobody has done it better than Novak, who holds the record for most grand slam single titles. Of course, Nadal and Federer aren’t far behind him and the legendary Sampras cracks the top five.

Most Australian Open Wins

As I alluded to earlier, Novak Djokovic is the most dominant player in Australian Open history, winning the event a record 10 times. At age 37, it’s possible he can still add to his hardware.

Most French Open Wins

Nobody has been better on clay when it mattered most than Rafael Nadal. He’s one of the best tennis players of all-time, but he was especially dominant at the French Open, where he still holds the record for most wins (14).

Max Decugis ranks second with eight all-time wins in this event, but Bjorn Borg has the best mark (6) in the Open era. Nobody else has more than three titles here in that span.

Most Wimbledon Wins

Wimbledon was Roger Federer’s bag (8). He won here eight times and thanks to the competitive nature of the prestigious tennis event, nobody has sniffed 10 wins yet. Pete Sampras and Novak Djokovic (7 each) are the closest.

Most US Open Wins

If we’re talking all-time, there is a three-way tie at the US Open, with Richard Sears, William Larned, and Bill Tilden all winning seven times. In the Open era only, Roger Federer and Pete Sampras are more recognizable names that have rattled off five title wins.
