The Thai Digital Advertising Association expects 2026 digital ad spend to grow only 0.3% to about 32,339 million baht, the weakest growth in 14 years. Meta (25% share) and TikTok (24%) lead, while YouTube, LINE and web/app ads are forecast to fall 15-24%. Brands are expected to pause in October-November and spend heavily in December. For a small business, this means ad spend should go to short-form video and creators on Meta and TikTok, and budgets may be cheaper to buy in the slower months, with the December peak in mind.
