Affiliate marketing is still profitable in 2026 because advertisers pay only for sales: US affiliate spending is forecast at $13.81 billion, up 11.3% and faster than the 6.7% growth of US retail e-commerce, and retail programs return about $11 in sales per $1 spent while travel programs return $19. The risks are real, though: Amazon cut some Associates commissions by up to 50% in 2026, and Google search referrals to news publishers fell 38% in the US in the year to November 2025.
Affiliate Marketing 2026 – Introduction
Why is affiliate marketing still profitable 2026? The answer is arithmetic. US advertisers are forecast to spend $13.81 billion on affiliate commissions this year, according to eMarketer, and the channel is expected to influence $241.03 billion in US e-commerce sales. That is about $17.50 in sales for every $1 paid out, and brands pay only after a sale happens. The Performance Marketing Association (PMA) found spending grew 49.8% between 2021 and 2024, nearly twice the pace of e-commerce.
Profit is not evenly shared. Advertisers enjoy strong returns, while publishers face falling search traffic and a major commission cut at Amazon. This report separates the two stories. It covers market size, return on ad spend, spending by industry, publisher types, AI search and the 2026 Amazon changes, and every figure carries its source. Data run through October 2026.

Source: eMarketer, US Affiliate Marketing Spending Forecast, September 2025; Performance Marketing Association, Industry Study 2025 (London Research, eight affiliate networks). The two series use different scopes, so 2025 and 2024 figures should not be compared directly.
The chart shows steady growth with one apparent dip. PMA counts $13.62 billion in 2024, while eMarketer’s narrower series shows $12.42 billion in 2025. They measure different things, so the dip is not a decline. Inside the eMarketer series, spend rises 11.3% to $13.81 billion in 2026, about 1.7 times the 6.7% growth of US retail e-commerce.
The table explains the appeal. PMA found the channel drove $113 billion in sales on $13.62 billion of spend, which works out to about $8.30 of sales per $1. Retail returns $11 per $1 and travel $19. Only 54% of publishers feel confident about their own affiliate business, and that gap between advertiser returns and publisher confidence runs through this report.

| US advertiser spend, 2025 | $12.42 billion | eMarketer |
| US spend forecast, 2028 | Nearly $16 billion | eMarketer |
| Global affiliate industry, 2024 | $18.5 billion | Cognitive Market Research |
| Affiliate platform market, 2026 | $23.8 billion | Grand View Research |
| Platform market growth, 2026–2033 | 5.9% a year | Grand View Research |
Source: eMarketer; Cognitive Market Research; Grand View Research, 2026. Global estimates vary by definition and range from about $17 billion to $28 billion.
Sales per dollar of spend is the number advertisers watch. eMarketer’s forecast implies $17.45 of influenced sales per $1 of commissions in 2026, and PMA’s 2024 study implies $8.30. The first counts sales the channel influenced, and the second counts sales it drove, which explains most of the gap. Both are well above $1, and neither is an audited total, because attribution in affiliate marketing is contested.
Global figures are looser. Cognitive Market Research values the industry at $18.5 billion in 2024. Grand View values the software and platform layer at $23.8 billion in 2026, growing 5.9% a year through 2033, and vendor estimates elsewhere run from $17 billion to $28 billion. For US planning, the eMarketer and PMA series are the most defensible. Many roundups also repeat a “$15 for every $1” return, but one 2026 review of affiliate statistics found no traceable study behind it.
Affiliate Marketing ROI 2026: Return on Ad Spend by Industry

Department stores | █████████████████████ 21
Office supplies | ████████████████████ 20

| Department stores | $21 : $1 |
| Office supplies | $20 : $1 |
| Travel | $19 : $1 |
| Auto parts | $19 : $1 |
| Clothing and accessories | $12 : $1 |
| Retail overall | $11 : $1 |
Source: Performance Marketing Association, Industry Study 2025, data from eight affiliate networks including Awin, CJ, Partnerize and Rakuten Advertising.
Every vertical returns at least $11 of sales per $1 of spend. Department stores lead at $21, followed by office supplies at $20 and travel and auto parts at $19. Retail overall averages $11, and clothing and accessories reach $12. Return on ad spend counts revenue, not profit, so margins decide how much of each sale is left after commissions and costs.
The model explains why budgets keep growing. Advertisers pay on results, so failed clicks cost nothing, and a Forrester survey commissioned by Awin found 81% of advertisers and 84% of publishers already run affiliate programs. Marketers ranked affiliate and partner marketing the third most effective channel, behind content marketing and pay-per-click.
Affiliate Spending by Industry 2026: Retail Loses Share
SHARE OF US AFFILIATE SPEND, 2024
Retail | █████████████████████████ 63%
Financial services | ██████ 15%
Travel | ████ 9%
Telecom | ███ 7%
Other | ██ 6%
| Industry | Share of Spend, 2021 | Share of Spend, 2024 |
|---|---|---|
| Retail | 76% | 63% |
| Financial services | 12% | 15% |
| Travel | 5% | 9% |
| Telecom | 3% | 7% |
Source: Performance Marketing Association, Industry Study 2025. The remaining 6% of 2024 spend is the balance across other industries.
Retail still dominates but is no longer the whole channel. Its share fell 13 points, from 76% to 63%, as other industries grew. Telecom more than doubled from 3% to 7%, travel rose 80% from 5% to 9%, and financial services climbed from 12% to 15%. Retail also generates a larger 71% of revenue, according to PMA’s reading of the data.
That diversification lowers risk for the channel as a whole. A retail slowdown now matters less than it did in 2021, because 37% of spend sits outside retail, up from 24%. It also explains why high-value verticals such as travel and finance pay publishers well. Higher order values and longer buying journeys can support commissions that thin retail margins cannot.
Affiliate Publisher Types 2026: Who Gets Paid
SHARE OF US AFFILIATE SPEND BY PUBLISHER TYPE, 2024
Cashback and loyalty | ██████████████████ 35%
Content publishers | ████████ 16%
All other types | █████████████████████████ 49% (balance)
| Measure | Figure |
|---|---|
| Cashback, loyalty and rewards share of spend | 35% |
| Content publishers’ share of spend | 16% (up from 15%) |
| Publishers confident in future of their affiliate business | 54% |
| Advertisers running affiliate programs | 81% |
| Publishers running affiliate programs | 84% |
Source: Performance Marketing Association, Industry Study 2025; Forrester Consulting survey commissioned by Awin, 2024.
Cashback and loyalty sites capture the largest share, at 35%, and content publishers hold 16%, up one point. Those numbers matter because content sites depend most on search traffic, the source now under pressure. Cashback sites are less exposed to search, and one 2026 analysis says they may hold a temporary edge as search changes. The other 49% is split among coupon, comparison, influencer and other partners.
Creators are the pressure point and the opportunity. Brands are moving budget toward people with audiences that buy, and the budget and engagement benchmarks behind that shift are in these influencer marketing statistics. The finding that 54% of publishers are confident, against 84% running programs, suggests most of them are staying in the channel while changing how they promote.
AI Search and Affiliate Traffic 2026: The Biggest Threat to Publishers

| Search referrals, small publishers (2 years) | −60% | Chartbeat via Axios |
| Expected search decline, next 3 years | −43% | Reuters Institute survey |
| Top-ranked click-through rate with AI Overview | −58% | Ahrefs |
Source: Reuters Institute, Journalism, Media and Technology Trends and Predictions 2026 (Chartbeat data, November 2024 to November 2025); Axios, March 17, 2026; Ahrefs data reported by The Media Copilot, May 27, 2026.
Search referrals are falling fast. Chartbeat data covering more than 2,500 sites show Google search traffic down 33% globally and 38% in the US in the year to November 2025, and small publishers lost 60% over two years against 22% for large ones. Ahrefs found click-through rates for top-ranked results 58% lower when an AI Overview appears. One affiliate specialist told Press Gazette that review and buyer’s-guide traffic fell by as much as 50% at some publishers, with affiliate revenue down 20% to 40%.
Read these figures carefully. They come mostly from news sites, not affiliate sites, and the Reuters Institute itself says it is unclear how much of the drop AI Overviews caused. Still, affiliate publishers rely on the same search clicks, and news executives surveyed by the Reuters Institute expect search traffic to fall 43% on average over three years. Click-based attribution is the model AI answers disrupt, and how marketers measure results without third-party cookies is covered in these cookieless advertising statistics.
Amazon Associates Commission Cuts 2026: What Changed
AMAZON ASSOCIATES RATE IN CATEGORIES CUT, 2026
Previous top rate | ██████████ up to 10%
Reported new rate | ████▌ as low as 4-5%
| Change | Detail |
|---|---|
| Commission cuts | Up to 50% for some publishers |
| Rates in affected categories | Up to 10% down to as low as 4%–5% |
| Milestone bonuses | Removed for most publishers |
| Operating Agreement update | Effective April 14, 2026 |
| Reported internal target | Cut program costs by 20% |
| Public rate ceiling | “Up to 10%” still advertised |
Source: Adweek, May 18–19, 2026 (interviews with seven publishers and partners); eMarketer, May 19, 2026; industry analyses of the April 14, 2026 Associates Operating Agreement update. Amazon did not publicly announce the rate changes.
Amazon’s cuts show the risk of building on one partner. Adweek reported rate cuts of up to 50%, and categories that paid up to 10% now pay as little as 4% to 5%. Milestone bonuses that rewarded higher volume were removed for most publishers, and publishers said the changes followed an instruction to cut program costs by 20%. One deal-site publisher expects its 2026 Amazon revenue to land 50% below its earlier projection.
The cuts did not hit everyone equally. Publishers with long relationships kept better terms, while paid-media-driven affiliate businesses were hit hardest. The response is diversification. Creators are moving toward video shopping and other programs, and how that income splits between ads, sponsorships and shopping is covered in these YouTube channel income statistics. A program that depends on one retailer’s discretion is a cost center for the retailer and a risk for the affiliate.
