Affiliate Marketing Statistics 2026: 25+ Sourced Facts & Trends

Affiliate marketing has grown from a niche performance-marketing tactic into a core acquisition channel for brands of every size, and the numbers below show why. Global spend is climbing past $18 billion, US advertisers alone are on track to spend nearly $14 billion in 2026, and affiliate-referred customers consistently outspend and out-retain shoppers acquired through other channels.

We pulled the following 25+ statistics from named, checkable reports — including Awin, eMarketer, the Performance Marketing Association, Cognitive Market Research, DemandSage, Grand View Research, PayScale, and Rewardful's own program-level data — rather than repeating unsourced round numbers that circulate on other "stats" pages. Where sources disagree (which happens often in this space, since methodologies vary widely), we've noted the range instead of picking one figure arbitrarily.
