The Affiliate Marketing Industry in 2026: How Big It Is, Who Gets Paid and Is It Still Profitable

Ask how big the affiliate marketing industry is and you'll get a confident number: $17 billion, sometimes $15.7 billion, usually "by 2027". I tried to trace it back to a study and couldn't. The figure travels from one statistics page to the next, and none of them shows who counted it or how.

There are real numbers, though. They come from an industry study of US networks, from the networks' own reports and from the public companies that live on affiliate commissions. Put together, they answer the 2 questions people actually search for: how big is the affiliate industry, and is affiliate marketing still profitable in 2026.

How big is the affiliate marketing industry?

The best-measured market is the US, and it's worth about $13.6 billion a year in spend. The Performance Marketing Association's 2025 industry study, built on data from 8 affiliate networks and more than 50 publishers, puts US affiliate marketing spend at $13.62 billion in 2024, up 49.8% from $9.1 billion in 2021. That's 14.42% a year, about 2 times as fast as US e-commerce, by the PMA's count. The same study says that spend drove $113 billion in e-commerce sales, 9.4% of all US e-commerce.

The global figure is where things fall apart. The "$17 billion" and "$15.7 billion" numbers repeated across statistics pages trace back to market research summaries and blog compilations that publish no method. Nobody adds up affiliate spend across countries the way the PMA does for the US, so any single global number is a guess with a decimal point.

Awin's figures show what a commission really is in money terms. The network says it generated £18 billion in revenue for advertisers and £1.2 billion for its publishers in its last financial year. That's about 6.7% of sales paid out to partners, a useful reality check when a program promises "up to 50%".

How many affiliate marketers are there?

Nobody knows, and the numbers networks publish overlap. Awin says it connects brands with "over a million partners worldwide" and 30,000 brands. But a single publisher usually works with several networks and in-house programs at once, so adding network totals together counts the same people many times.

The more useful question is how many of them earn money, and that's even harder to answer. The income surveys quoted on statistics pages are polls of self-selected audiences, often run by companies that sell affiliate courses, and I couldn't find one with a published method. What public data does show is concentration: on Awin, as the next section shows, a handful of partner types collect most of the sales.

Where the money goes: coupons, cashback and creators

The channel is no longer just coupon and cashback sites, but they still dominate. In its 2026 Power 100 index, Awin found influencers and bloggers are now the second most common partner type, behind the combined group of coupon and cashback sites, and content creators' representation was up 180% on the previous index in 2024.

Inside the incentive sites, the money moved to closed user groups. These are reward schemes for students, NHS staff, employees and other closed audiences. Comparing its top 10 global coupon partners with its top 10 closed user group partners by share of sales, Awin found coupon sites fell from 66% to 48% between 2024 and 2026, while closed user groups rose from 34% to 52%, overtaking coupon sites for the first time.

Measurement decides who gets paid, not just who drives the sale. impact.com describes PUMA's cashback partner capturing 80% of program revenue while every partner was measured and paid the same way. Once PUMA paid each type for what it actually did, active partner growth doubled and its cost per acquisition fell 30%. Our breakdown of types of affiliates covers how each partner type is paid.

Creators are moving platforms, too. Among creators signing up through Awin's app, Instagram's share as the main platform fell from 78% in 2024 to 62% in 2026, while TikTok's grew from 6% to 15%.

Is affiliate marketing still profitable? What public companies report

The listed affiliate businesses give the clearest answer, because they have to publish numbers. And in 2026 those numbers are mostly falling:

Future plc blames search. It attributes the fall in e-commerce affiliate revenue to weaker site traffic after disruption in the search ecosystem. Catena Media is blunter: generative search "continued to transform how users discover brands online, reducing new traffic across the affiliate industry", and its own search rankings fell.

Regulation can switch off a whole market overnight. On September 25, 2026, Brazil's government introduced a Provisional Measure banning the operation, offering and advertising of fixed-odds betting nationwide. Most of Better Collective's Brazilian revenue came from revenue share with licensed operators, so it now assumes none of it for the rest of 2026. India's Promotion and Regulation of Online Gaming Act, 2025, whose rules took effect on May 1, 2026, did the same to online money games there.

Our Amazon Associates card has the current published rates, and our review of Raketech's Q2 2026 report shows how another listed affiliate presented a 17.6% revenue fall.

Why search-led affiliates are losing clicks

AI summaries on Google answer the question before the click. Pew Research Center tracked the browsing of 900 US adults in March 2025. 18% of their Google searches produced an AI summary. When one appeared, people clicked a traditional search result in 8% of visits, against 15% when there was no summary, and clicked a link inside the summary itself in just 1% of visits. They also ended their browsing session on 26% of pages with a summary, against 16% without.

For a review site, that's the business model under attack. A "best X" page that used to collect the click now competes with an answer above it. That's the traffic Future and Catena say they lost, and it's why publishers who depend on Google organic traffic are the part of the industry that's shrinking.

The sites that win in AI answers are the ones affiliates can't own. Pew found Wikipedia, YouTube and Reddit were the most cited sources in both AI summaries and standard results. That's part of why affiliates now buy placements there instead: see our guide to Reddit ad formats.

Where affiliates still make money in 2026

Paid traffic doesn't depend on Google's rankings. Affiliates who buy their own traffic, the media buyers, trade the search risk for ad costs, account bans and regulatory risk, but a ranking update can't take their traffic away overnight. The trade-off is cash: our analysis of why affiliates don't scale past $10K a month shows how holds, caps and accounts become the ceiling.

Closed audiences and creators are growing. Closed user groups and creators are the partner types gaining share on Awin, and both own an audience that doesn't depend on a search click.

Programs, not just channels, can change the deal. Amazon's cuts show that a single program can reprice your traffic without telling you. Keep your links on a tracker or your own redirects, so you can move them when a program changes; our guide to affiliate link management explains how.
