The ATP China Open, held annually in Beijing as part of the ATP 500 series, presents a distinctive betting landscape shaped by several factors. The tournament's position in the late-season Asian swing means players are managing fatigue from a long calendar year, creating volatility that sharp bettors can exploit. Tennis scoring's inherent structure — where a single break of serve can decide a set — amplifies this variance. Market depth for the China Open is solid but not as extensive as for Grand Slams or Masters 1000 events; bettors will find robust moneyline and set betting markets, but prop offerings like game handicaps and exact score lines can thin out considerably in early rounds, particularly for lower-profile matchups.

Vigorish on ATP 500 events like the China Open tends to sit in a middle band — tighter than Challenger-level or early-round ATP 250 markets, but wider than what books offer on Grand Slam marquee matches. Expect moneyline margins in the range of 4-6% from major sportsbooks during early rounds, compressing toward 3-4% as the draw reaches the quarterfinals and beyond. This compression happens because books receive sharper action and higher volume on matches featuring top-ranked players, incentivizing them to post more competitive lines to attract handle. Comparing vig across books becomes especially valuable in the first two rounds, where pricing discrepancies are most pronounced.

The tournament typically runs in late September or early October, coinciding with the broader Asian swing that includes events in Tokyo, Shanghai, and elsewhere. This scheduling creates unique dynamics: players arriving from different time zones may struggle with jet lag, and those who performed well the prior week in Tokyo often carry form but also fatigue. Beijing's outdoor hard courts and autumn weather — occasionally humid with the possibility of rain delays — can disrupt match rhythms and affect serve-dominant players differently than baseline grinders. Bettors should pay close attention to head-to-head records on hard courts specifically, recent workload across the Asian swing, and any nagging injuries that tend to surface this deep into the season.

Frequently Asked Questions

What are the best ATP China Open lines today?

The table below shows which sportsbook has the best available price on each side of every upcoming ATP China Open event. Line shopping across multiple books can save you 1–3% per bet compared to sticking with a single sportsbook.

What is vig (vigorish) in sports betting?

Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.

How often is this data updated?

We pull fresh odds from The Odds API every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.

How is the vig grade calculated?

Each sportsbook is graded on average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.

Why does lower vig matter for bettors?

Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.

What sportsbooks do you track?

We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnything). Data comes from The Odds API, which aggregates real-time lines from licensed sources.

How We Calculate These Numbers

Data Source
All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
Update Frequency
We pull a fresh snapshot of every tracked market every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
Vig Calculation
Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
Per-Market Breakdown
We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
Grading Scale
Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
Trend Tracking
We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
