The wealth rankings of Thailand's billionaires for 2025 have revealed notable shifts, influenced by market conditions and individual business developments. The Chirathivat family's wealth experienced a 13% decline, bringing their total net worth to $8.6 billion, attributed to weakened consumer sentiment in the retail sector. In a significant development last October, the Central Group, led by the Chirathivat family, entered a partnership with Saudi Arabia’s Public Investment Fund, which acquired a 40% stake in British retailer Selfridges, while the Chirathivat family retains the remaining 60% stake.

Overall, 19 individuals in the billionaire list faced declines in their net worth. Notably, Prayudh Mahagitsiri, the coffee magnate, experienced a decrease after the conclusion of PM Group's long-standing joint venture with Nestlé. The list also reflects the passing of two notable figures since the last ranking: Vanich Chaiyawan, chairman emeritus of Thai Life, and Pongsak Viddayakorn, cofounder of Bangkok Dusit Medical Services. Their fortunes are now represented by the Chaiyawan family and the Viddayakorn family, respectively.

Despite a decrease in the minimum net worth requirement to qualify for this year's list—from $550 million to $420 million—four individuals fell off the rankings, including renewable energy magnate Somphote Ahunai, due to financial difficulties facing his company, Energy Absolute.
