Analysts view the 2026 ASEAN Cup Group A encounter between Indonesia and Cambodia as a lopsided contest. With the backing of their home crowd and a superior lineup, Indonesia is positioned as the favorite ahead of the opening match.
Based on forecast models and signals from international betting markets compiled from statistics sites and bookmakers, Indonesia has approximately a 75-85% chance of securing victory. The likelihood of a draw ranges from 10-15%, while Cambodia's chances of springing an upset stand at just 5-10%.
| Outcome | Probability |
|---|---|
| Indonesia Win | 75-85% |
| Draw | 10-15% |
| Cambodia Win | 5-10% |
Several other statistical models arrive at a similar evaluation. Although specific percentages vary among prediction algorithms, Indonesia remains the prime candidate to secure all three points thanks to home advantage and superior player quality.
Indonesia enters the 2026 ASEAN Cup with high expectations under coach John Herdman, who was appointed after the World Cup qualifying campaign. The archipelago nation's goal is to conquer its first ASEAN title in history after several near-misses in the final.
Home advantage is also a crucial factor. Indonesia will play in front of tens of thousands of supporters and boasts a deep roster with many naturalized players, some active in Europe or with experience in top-tier competitions. Compared to Cambodia, the hosts have superior speed, fitness, and international experience.

Moreover, Indonesia understands that a convincing win over Cambodia would create a major advantage in the race for the top two spots in Group A, which also includes defending champions Vietnam and Singapore.
Despite being heavily underestimated, Cambodia is not a team that gives up easily. In recent years, the squad has improved through a youth-driven rebuilding process and a more proactive style of play.
Cambodia also recently played a competitive match against Singapore in the opening round, losing narrowly, which shows they can still cause trouble if they capitalize on counter-attacking opportunities. Under less pressure, this side could aim for at least a point if they maintain defensive focus.
Drawing on international prediction models, squad quality, home advantage, and the overall strength comparison between the two teams, Indonesia stands as the clear favorite to win the opening match of the 2026 ASEAN Cup.
If they perform to their potential, John Herdman's squad will likely control the game and create a difference as early as the first half. The most commonly predicted scores are 2-0, 3-0, or 3-1 in favor of the home team.
