HOW WE RUN FUTURES

How open88 Manages the Futures Market

Transparency on how futures are priced, settled, and adjusted matters more on long-horizon bets. Here's what you can count on when you place a tennis futures wager with us.

Odds Transparency

Current futures prices are displayed alongside the implied probability so you can judge the line clearly — no hidden margins buried in formatting. Prices update when seedings or player news changes.

Withdrawal Rules Published

Our house rules on player withdrawals and tournament cancellations are published in the betting rules section before you place a futures wager — no surprises at settlement time.

Market Integrity Checks

We monitor futures markets for unusual activity and adjust lines accordingly. If a line is suspended ahead of a major announcement, the board shows a clear suspended status rather than silently removing it.

Settlement Timeline

Futures bets settle within one business day of the official tournament result being confirmed. Winnings post directly to your account wallet, where you can move them to PayPal or Venmo.

open88 What Our Tennis Futures Board Covers

What Our Tennis Futures Board Covers

Our futures board runs deeper than tournament-week moneylines. You can lock in a position on Australian Open, French Open, Wimbledon, or US Open outright winners months before the draw is posted. We also carry ATP and WTA leading ranking futures, year-end championship odds, and next-Major-winner lines that update as players report injuries or withdraw. Odds shift when seedings are announced, so checking

the board early gives you access to longer prices before the market tightens around the favorites. Access depends on your state's applicable laws and eligible regions.

Tennis Futures Terms Worth Knowing

New to futures betting on tennis? These are the terms that come up most when you're reading a Grand Slam outright board or evaluating a season-long line.

01
What is an outright winner bet in tennis?

An outright winner bet is a futures wager on which player wins an entire tournament. You place it before the draw and your stake rides until the final match is played.

02
What does 'each-way' mean on a tennis futures bet?

Each-way splits your stake into a win portion and a place portion. If your player reaches the final or semifinal depending on terms, the place part of the bet pays out at reduced odds.

03
What is a futures market void or non-runner rule?

If a player withdraws before competing, most futures books void that selection and return the stake. Always check the specific rules posted on the market before placing.

04
What does 'implied probability' mean on a futures line?

Implied probability converts American odds into a percentage chance the outcome happens. A +400 line implies roughly a 20 percent chance of winning, before the house margin is factored in.

05
What is the difference between a Grand Slam future and an ATP ranking future?

A Grand Slam future is a bet on one specific tournament's winner. An ATP or WTA ranking future is a season-long position — typically on who finishes the calendar year ranked number one.

06
What does 'chalk' mean in tennis futures?

Chalk refers to the heavily favored player in a futures market — the short-priced option the majority of money backs. Betting chalk means accepting low odds for a higher-probability outcome.
