Six nations compete in a round-robin format, with each tie played as best of three rubbers (two singles, one doubles).

The top two teams advance to the Billie Jean King Cup play-offs in November 2026; the bottom two drop to Group II. If you're new to the sport, understanding how tennis scoring works can help you follow the action more closely.

Quick Picks

Our pick: New Zealand to win

Value bet: Indonesia to qualify

Long shot: India across matches in handicap markets

Betting Preview

The six nations to be participating in Asia/Oceania Group I are:

• India (hosts)
• Indonesia
• South Korea
• Mongolia
• New Zealand
• Thailand

Many top players will be competing in this section of the tournament. New Zealand named Erin Routliffe, Lulu Sun, Monique Barry, Valentina Ivanov, and Aishi Das, captained by Matt Hair. Indonesia includes world No. 40 Janice Tjen.

Betting Markets to Watch

New Zealand and Indonesia stand out as pre-event favourites for the top two spots, thanks to higher-ranked players such as Erin Routliffe for NZ and Janice Tjen (top 50) for Indonesia.

Thailand can be considered very competitive with the squad they have been able to select, and should be able to overcome nations perceived as weaker, especially with players lower down the rankings.

Peangtarn Plipuech offers plenty of experience as an accomplished doubles player, having ranked inside the top 100 as recently as 2024. Understanding different tennis playing styles explained can help you assess how these matchups might unfold.

South Korea offers solid depth across singles and doubles. Their history in Asia/Oceania Group I, including recent ties and consistent performance (e.g., most wins records by players like Sung-Hee Park), positions them as challengers beyond just top singles.

Mongolia and host India appear vulnerable for the bottom two positions. Mongolia earned promotion recently but lacks top singles rankings, while India's players (e.g., Ankita Raina, around No. 300) trail despite home advantage.

Still, it's worth noting that they could be big underdogs in particular games, which could see them offer value in specific markets like the handicap or match props.

We think the most likely winners of Group 1 Asia/Oceania in the Billie Jean King Cup will be New Zealand. They have a better pool of players than other nations and should thrive on the Indian hard courts.

Our long shot is for India to have a solid competition and cause some upsets throughout.

They have home-court advantage, and the home support could help them power through against the nations that find the pressure too much to handle.
