Thailand’s digital ad landscape is expanding fast, supported by near-universal connectivity and heavy social usage. In 2026, Thailand has 67.8 million people online, equal to 94.7% of the population, and 56.6 million social media identities (79.1%). Against that backdrop, multiple forecasts point to a sharp step-up in spend. Research and Markets expects Thailand’s digital ad spend market to reach US$6.60 billion by 2026, reflecting 11.0% annual growth. Another cited benchmark puts 2025 digital advertising spend at USD 5.95 billion, also growing 11% annually through 2029.
Audience scale explains why budgets keep shifting to the biggest platforms. LINE reported 56 million monthly active users in late 2025, equal to 78.2% of Thailand’s population and 82.6% of internet users, making it a default channel for ongoing CRM via Official Accounts. Meta still delivers reach, with Facebook ads reaching 51.5 million people in Thailand in 2026, while Instagram’s ad reach stands at 20.6 million. Video remains central, and YouTube’s ad reach is listed at 47.2 million. Daily social media time is 2 hours 35 minutes, reinforcing why brand and performance activity both cluster where attention concentrates.
TikTok Shop and Influencers Push Spend Toward Performance
TikTok’s ad inventory is expanding, and that scale is colliding with commerce. DataReportal reports TikTok had 56.6 million users aged 18 and above in Thailand in late 2025, with potential ad reach increasing by 3.00 million (+5.6%) between end-2024 and late 2025. TikTok ads reached 96.3% of adults aged 18+ and equaled 83.5% of Thailand’s internet user base at the end of 2025. On the spend side, DAAT data cited in local marketing stats shows Meta (Facebook and Instagram) at around 26% of digital ad spend, followed by TikTok at 16%, edging past YouTube at 15%. This is a clear signal that short-form video and creator-led formats are reshaping buying plans.
Social commerce makes the budget shift more measurable. Thailand’s fastest-growing e-commerce segment is social commerce, which hit USD 5.20 billion in 2025 and grew 18.6% year on year. In platform behavior, Shopee leads with 75% usage among online shoppers, followed by Lazada at 67%, while TikTok Shop is increasingly prominent with 51% awareness and climbing toward 40%+ active usage. As these platforms merge entertainment and conversion, more spend naturally moves to performance tactics such as search, social conversion, and affiliate activity, alongside video placements across YouTube, TikTok, and Instagram Reels.
Influencers sit at the center of this reallocation. The creator economy in Thailand was valued at 45 billion baht in 2024, reflecting the growing business model around influencers, micro-influencers, and content creators. For brands planning in the Thailand digital advertising market, the takeaway is not just “more spend,” but different spend: more creator-led video, more commerce-integrated campaigns, and more focus on measurable outcomes. Meanwhile, audience realities still matter: X is listed at 13.3 million (down 1.7%), and DataReportal flags Reddit’s 4.15 million figure as influenced by a reporting change, reinforcing why most large budgets continue to concentrate on the dominant platforms.
