Affiliate marketing is bigger than it has ever been. But where the growth is coming from has shifted significantly in the past 18 months.
The Industry Size
US affiliate spending is projected to reach $13.81 billion in 2026, according to a September 2025 EMARKETER forecast. That makes affiliate marketing one of the largest performance marketing channels in the US market. Global figures put the industry on a trajectory toward $31 billion by 2031.
Latin America’s e-commerce market is projected to reach $215.31 billion in 2026, presenting significant expansion opportunities for affiliate marketers targeting emerging markets. The geographic story of affiliate growth is increasingly about markets outside the US, UK, and Western Europe.
Reddit’s r/affiliate marketing at https://www.reddit.com/r/affiliatemarketing/ regularly publishes income reports from affiliate marketers working across different geographies. The emerging market threads are consistently showing higher commission rates and lower competition for keywords in markets like Brazil, Mexico, and Southeast Asia.
The Channel Mix in 2026
SEO is the most used channel at 69%, followed by social media at 67%, content marketing at 65%, and blogging at 64%. TikTok Shop GMV reached $23.4 billion, and mobile-first affiliate funnel trends are reshaping how commissions are earned.
The TikTok Shop number is the most striking single data point in the current affiliate landscape. A commerce platform that barely existed three years ago is now generating tens of billions in GMV, and affiliate commissions are a significant part of how products move through that system.
Where AI Is Disrupting the Channel
Generative AI chatbots are reshaping the shopping journey that affiliate marketing depends on. Consumers who use genAI have adopted it for price comparison at 54%, deal finding at 41%, and review checking at 41%.
This creates a core tension for the channel. AI chatbots perform the same tasks that affiliate publishers built businesses around: product comparison, deal hunting, and recommendation.
Di X padahttps://x.com/search?q=affiliate+marketing+AI+disruption+2026the conversation is split between publishers who see AI as an existential threat and those who see it as a distribution layer to optimize for.
The ones treating AI search as a new traffic source to optimize for are building for GEO — generative engine optimization — rather than waiting for the old organic traffic to come back.

The consensus view is that AI is raising the floor on content quality while lowering the ceiling on generic content. The affiliate sites that survive will be the ones where human expertise is genuinely irreplaceable.
