Ask most punters what summer betting looks like, and they'll say football. Fair enough. This year, the World Cup was the biggest betting event the US has ever seen, and Hard Rock Bet likened it .

But take football off the table, and the summer slate is still rammed. Below, Ìýreveals the five sports that kept betting sitesÌýbusy, with every figure sourced. Money is shown in U.S. dollars at exchange rates on Oct. 19, 2026, and all data is accurate as of that date.

Of course, none of this indicates who'll win anything. It tells you where the money goes, which isn't the same thing at all.

1. Horse racing — the one that never takes a summer offÌý

  • Hong Kong racing turnover 2025/26:Ìý, up 3.2%
  • World Pool (global shared racing pools) 2025:Ìý, across all World Pool races
  • Melbourne Cup 2025:ÌýA record Ìýbet on the race itself, up 16.4%

Racing's flat-cap image hides a serious betting machine, and it broke records again over the past 12 months.

Start in Hong Kong. The Jockey Club took Ìýon racing in the 2025/26 season, up 3.2% on the year before. A record Ìý$4.39 billion of that came from punters overseas betting into Hong Kong's pools, up 8.3%.

That overseas money is where Royal Ascot comes in. Ascot runs on World Pool, the Hong Kong-run system that lets punters on different continents bet into one shared pot. The 2025 meeting took around $201 million through World Pool, 10% up on 2024 and only about . Across 2025 as a whole, World Pool turnover on races outside Hong Kong Ìýto $1.19 billion over 57 race days. There's no full-meeting World Pool figure for Royal Ascot 2026 yet.

Not that 2026 was plain sailing. Coral and Ladbrokes said staking came in a little under expectation, and Ìýrunning alongside it. Then Ìýmade it an expensive week for the bookies. Not a week to be a bookmaker.

Down under, the race that stops a nation stopped it harder than ever. A record $72.7 million went on the 2025 Melbourne Cup, beating the 2021 record of $157.6 million, and Cup Day as a whole took Ìý$267 million. Racing Victoria says the Cup takes Ìýthe turnover of any other Australian race. The 2026 renewal isn't run until November, so 2025 is still the latest result (November is stretching the definition of summer, granted, but it's too big to leave out).

2. Baseball — summer's quiet workhorseÌý

  • Missouri, July 2026:ÌýMLB took Ìýof the $246.8 million total handle, more than half
  • Indiana, July 2026:ÌýBaseball handle of , 17.3% of the state's $384.2 million
  • Legal U.S. reach:ÌýÌýrun legal sports betting, around 31 with statewide online betting, as of July 2026

With the NBA and NHL done and the NFL not back yet, Ìýthrough July and August. The Ìýopened on 25 March with the Giants vs. Yankees, the earliest traditional Opening Day the league has staged, and runs to 162 games before the October World Series.

The state reports show how much of the summer it soaks up. In Missouri, live only since December 2025, baseball was more than half of all July handle (the total amount staked). That's well clear of multi-leg parlays at $79.6 million, and soccer at Ìýin a World Cup year. Indiana's Ìýput baseball at 17.3% of handle, with a big chunk of the month's money going on NFL futures that won't settle until the new year.

It wasn't all one-way traffic for the sportsbooks, mind. Nevada's baseball win in June 2026 came to $17.9 million, Ìýon a record June 2025, and the Ìýpulled casual money towards football through June and July. But a game every day, deep player-prop markets and new wrinkles like the 2026 automated ball-strike challenge systemÌýkeep baseball the backbone of U.S. summer betting.

3. Cricket — huge, mostly hidden, and hit hard this yearÌý

  • India:ÌýCricket estimated at 80%-90% of all sports betting revenue, with participation rising to around 370 million during the IPL
  • IPL 2026 (March 28-May 31):Ìý, then seven straight weeks of decline under India's new online gaming ban
  • UK:ÌýThe Hundred's Ìýran July 21-Aug. 16

No sport changed shape more this year than cricket.

Its betting heartland is India, where the Think Change Forum reckons cricket drives 80%-90% of all sports betting revenue, almost all of it . In August 2025, India passed the PROG Act, Ìýon real-money online games, and enforcement landed just as IPL 2026 got going.

What followed was a season like no other. Betting demand on the opening match, RCB vs. Sunrisers Hyderabad, was the highest for an IPL opener in nine seasons of Blask tracking. Then it fell for seven weeks straight. Authorities had blocked around 8,400 betting sites and apps before a ball was bowled, and told VPN providers to cut access.

You'll still see big headline numbers for IPL betting floating about. Take them with a pinch of salt. Because almost all of that betting is illegal, they're estimates, not reported figures.

In England, the cricket summer was as busy as ever. Ìýplayed five T20Is and three ODIs between July 1-19, then Ìýran from July 21 to Finals Day at Lord's on Aug. 16. The Ìýincluded defending champions MI London, formerly Oval Invincibles.

4. Tennis — built for betting in-playÌý

  • Wimbledon 2026:ÌýJune 29-July 12,
  • Operator view:ÌýBetway called Wimbledon by far Ìýon the tennis calendar for its brand
  • Long-cited benchmark:ÌýCoral has said roughly Ìýcomes during the Wimbledon fortnight, an older figure, not updated for 2026

Tennis could have been designed with in-play betting in mind. Momentum swings on grass make Ìýat Wimbledon, and UK bookmakers price up hundreds of markets on the event, .

The 2026 Championships gave in-play punters plenty to work with. Ìýwas blown open early when Aryna Sabalenka, Iga Swiatek and Elena Rybakina all went out, reshuffling the outright market mid-tournament. Ìýwent all the way to the men's semi-finals before Alexander Zverev ended the run.

In the end, though, the favorites largely delivered. World No. 1 Ìýbeat Novak Djokovic in straight sets in the semis, then came from a set down to beat Zverev 6-7, 7-6, 6-3, 6-4 and keep his title, . The bookmakers' Ìýfor the fortnight included retirement-rule guarantees and in-play insurance.

Over in the U.S., prediction-market platforms now list tennis, too, with Ìýdrawing the most volume.

5. Golf — four weeks that matter, and a 200-1 shockÌý

  • Peak event:ÌýÌýThe Masters its fourth-biggest betting event of the year, behind only the Grand National, the Super Bowl and the Champions League final
  • Majors matter:ÌýThe four majors produce about , and The Masters alone about 40% of that
  • 2026 shock:ÌýÌýwon The Open at up to 200-1

Golf doesn't have baseball's daily volume, but the four majors bring a proper betting bonanza, and 2026 was a year for long shots. , Aaron Rai the PGA Championship and Wyndham Clark the US Open before the final major at Royal Birkdale.

The Masters set the tone in April. At Betway, Bryson DeChambeau Ìýof all outright bets, more than any other player, while favorite Scottie Scheffler drew 9%.

Then came The Open. New Zealand's Ryan Fox, priced at 200-1 with Caesars and 150-1 to 170-1 elsewhere, Ìýwith a third-round 62 and birdied the 72nd hole to win. He finished Ìýof Cameron Young, with defending champion and favorite . Fox banked Ìýfor it, and he was Ìýto win a men's major this year.

That's golf betting in a nutshell. Even the favorite is up against a whole field, and the big prices land just often enough to keep everyone interested.

The bookmakers keep finding new angles, too, such as Ìýon every par three at Augusta.

The betting slip doesn't take a holiday

Summer 2026 showed again that the "quiet season" is a myth. Racing set turnover records in Hong Kong and at Flemington. Baseball carried U.S. sportsbooks through July. Cricket stayed a betting giant even as India's ban hit IPL demand. Tennis lived on in-play action through Wimbledon, and golf served up a 200-1 shock at Royal Birkdale.

The World Cup took the headlines. These five kept punters busy before, during and after it. So next time someone tells you summer is quiet for betting, point them at a racecard, a box score, a scorecard or a leaderboard.

Methodology

All data is accurate as of Oct. 19, 2026, and comes from the sources listed below, with each figure cited where it appears. This update replaces the previous version's global "share of betting revenue" estimates with event- and regulator-level figures, because no comparable 2026 global breakdown has been published. The old IPL betting estimate and the 2023 cricket market valuation were removed because they couldn't be verified for 2026.
