The US Open isn’t just tennis’s final major—it’s a proving ground for in-play excellence. And for forward-thinking sportsbooks, it presents a chance to drive sustainable acquisition, boost engagement, and differentiate via a sport uniquely built for live betting.
With a bold new mixed doubles format and a digitally native audience, Flushing Meadows could be the smart marketer’s secret weapon this year.
Why tennis remains the in-play king
According to Entain, 90% of all tennis bets are placed in-play. Globally, tennis is now the second-most popular in-play sport—behind football in the UK and basketball in the US.
The appeal is structural. Unlike football’s fixed halves, tennis offers:
- High-frequency betting windows – every point is a new opportunity.
- Volatility with structure – set breaks and momentum swings drive repeat engagement.
- Extended session lengths – five-set epics can deliver 6+ hours of continuous betting.
The implication is clear: operators optimising their US Open strategy can extend session time, increase bet frequency, and build cross-sell momentum ahead of the NFL and Premier League Q4 ramp.
A different kind of Grand Slam: Mixed doubles, reimagined
This year’s US Open marks a shift in tennis storytelling—with the new-look mixed doubles format designed for shorter, punchier matchups that reflect how people consume sport today.
In a world where attention spans are shrinking, shorter formats win. Mixed doubles now offer fast-paced, high-stakes contests without the six-hour slog of a five-set marathon—perfect for in-play bettors looking for more action in less time.
- Shorter matches = better engagement
Fast, accessible contests that fit modern viewing and betting habits.
- Big players in unison
The only place you’ll see top stars from the men’s and women’s game team up.
- New storylines that sell themselves
From unexpected partnerships to potential upsets—this is a marketer’s dream.
Whether it’s Alcaraz and Raducanu joining forces or Olga Danilovic with Novak Djokovic, the format opens the door to creative campaigns that resonate across multiple fan segments. For sportsbooks, that’s an opportunity to craft standout content, launch novelty markets, and build buzz with casual fans.
What are bettors actually backing?
Despite tennis’s complexity, three markets drive 85% of in-play stakes:
- Match Winner – volatile throughout, even in one-sided contests
- Current Game Winner – frequent settlements, point-by-point engagement
- Set Winner – perfect for bettors seeking mid-length markets
But the real growth is happening elsewhere. Micro-markets like ‘next point winner’ and ‘exact score’ are seeing double-digit growth—especially among mobile-first users and casual fans.
A smart in-play strategy means surfacing these markets contextually, not overwhelming the UI. The right mix can increase dwell time without sacrificing user experience.
Understanding the tennis better—and their value
YouGov profiling reveals tennis bettors are younger, more affluent and more digitally engaged than the average sports fan. They:
- Engage heavily via mobile
- Are open to backing new or international players
- Show high cross-sport interest—making them ideal for broader acquisition strategies
During Grand Slams, these users become even more valuable. They bet more frequently, stay on-platform longer, and are more likely to explore new markets. This makes the US Open not just a short-term opportunity, but a trigger point for longer-term customer value.
Our five ways to serve tennis in-play bettors
- Prioritise speed
Sub-two-second latency between point completion and market update is critical. Even minor delays cost conversions.
- Invest in premium data feeds
Official ATP/WTA feeds reduce settlement disputes and enable faster market creation.
- Surface momentum markets
Test “next break of serve” or “player to win three games in a row” to reflect real-time narrative shifts.
- Geo-target creatively
Launch Alcaraz-focused offers in Spain, while using Raducanu/Emma Navarro promotions in UK and US markets respectively.
- Tap into parlay culture
Same-match tennis parlays, made popular by FanDuel, appeal to recreational bettors and increase average stake size.
The final Slam, the final say
Tennis isn’t a niche sport. It’s a cornerstone of the in-play economy—especially during Slams. And the US Open, with its prime-time slots and cross-market appeal, is arguably the most commercially potent of all.
Operators that nail their in-play offering now won’t just win Q3—they’ll lay the groundwork for sustained growth into NFL, Champions League and beyond.
