The ASEAN Cup 2026 creates an extraordinary milestone in the history of the competition, with all four semifinalists having once lifted the trophy: Vietnam, Thailand, Malaysia, and Singapore.
In Group A, Vietnam secured the top spot and will face Malaysia, the runner-up of Group B. The other semifinal pair is a clash between Thailand, the Group B winners, and Singapore, the Group A runners-up.
Notably, all four teams boast impressive ASEAN Cup championship histories. Thailand is the most successful with seven titles: 1996, 2000, 2002, 2014, 2016, 2020, and 2022. Singapore ranks second among the four in terms of titles with four triumphs: 1998, 2004, 2007, and 2012. Vietnam has won the championship three times: 2008, 2018, and 2022. Meanwhile, Malaysia has claimed the regional crown once, in 2010.

Thus, the four semifinalists of the ASEAN Cup 2026 have collectively won 15 championships in the tournament's history. Thailand accounts for nearly half of these titles, while Singapore and Vietnam have also repeatedly asserted their dominance in the regional competition.
This is the first time the ASEAN Cup has featured a semifinal round where all four teams have previously been champions. In 2007, the same quartet of Thailand, Vietnam, Singapore, and Malaysia appeared in the semifinals. However, at that time, Vietnam and Malaysia had not yet secured their first ASEAN Cup titles. Thailand and Singapore had already won, while Vietnam claimed its first championship only in 2008. Malaysia had to wait until 2010 for its inaugural triumph.
Nearly two decades later, these four teams once again find themselves together in the round of the strongest four, but this time, each has at least one championship to its name.

The presence of Vietnam, Thailand, Malaysia, and Singapore also highlights the special nature of the ASEAN Cup 2026. No surprise was big enough to allow a team that had never won the title to break into the semifinals. Instead, the four most traditional powers in the region continue to compete for the prestigious trophy.
Vietnam and Malaysia will face off in the first semifinal, while Thailand takes on Singapore in the other clash. With a combined total of 15 past championships, the ASEAN Cup 2026 semifinals are undoubtedly a gathering of the most storied forces in Southeast Asian football.
