Affiliates and partners drove 20.4% of all US online holiday-season revenue in 2025, a 15.9% year-over-year jump (Adobe Analytics, 2025 Holiday Shopping Report). On Cyber Monday alone the affiliate and partner share reached 21.8% of a record $14.25 billion in online spending (Adobe Analytics, Cyber Monday 2025). US advertisers are on track to spend $13.81 billion on the channel in 2026, up 11.3% from 2025, while overall retail e-commerce grows just 6.7% (eMarketer, US Affiliate Marketing Spending Forecast 2025).

1. Market Size and Advertiser Spend
Affiliate is no longer a rounding error in the media plan. US advertisers will spend an estimated $13.81 billion on affiliate marketing in 2026, growing 11.3% year over year while overall US retail e-commerce grows only 6.7% (eMarketer, US Affiliate Marketing Spending Forecast 2025). That gap is the headline: brands are moving budget into a channel that pays on outcomes as other channels get more expensive. Global market-size figures diverge sharply depending on whether an analyst counts advertiser commission spend, platform revenue, or total attributed sales, so treat any single global number with caution.
| Metric | Value | Source |
|---|---|---|
| US affiliate marketing spend, 2025 | $12.42 billion | eMarketer, 2025 |
| US affiliate marketing spend, 2026 (forecast) | $13.81 billion (+11.3% YoY) | eMarketer, 2025 |
| US e-commerce sales attributed to affiliate, 2026 | $241.03 billion | eMarketer, 2025 |
| Affiliate spend growth vs. retail e-commerce growth, 2025-2026 | 11.3% vs. 6.7% | eMarketer, 2025 |
| Partner-referred GMV on impact.com, 2025 | $120 billion | impact.com, 2025 Momentum Report |
| Global industry estimate, 2025 (channel spend) | ~$17 billion, tracking to ~$20 billion by end of 2026 | AffiliateBooster State of Affiliate Marketing Report, 2026 |
Flag: the global ”~$17 billion to $20 billion” range is a vendor-report estimate; platform-market forecasts that fold in software revenue run considerably higher and are not directly comparable.
2. Affiliate’s Share of E-Commerce
Peak-season data is the clearest read on how much of online retail flows through partners, because Adobe measures actual transactions rather than survey recall. Affiliates and partners drove 20.4% of US online holiday revenue in 2025, up 15.9% year over year (Adobe Analytics, 2025 Holiday Shopping Report). The fastest riser inside that number is social, the proxy for influencer-led selling, which grew 40.3% year over year over the full season and 56.5% on Cyber Monday. For the broader retail picture, see our e-commerce statistics for 2026.
| Metric | Value | Source |
|---|---|---|
| Affiliate/partner share of US holiday e-commerce revenue, 2025 | 20.4% (+15.9% YoY) | Adobe Analytics, 2025 Holiday Report |
| Affiliate/partner share on Cyber Monday 2025 | 21.8% (up from 20.3% in 2024) | Adobe Analytics, Cyber Monday 2025 |
| Social media revenue share, 2025 holiday season | 4.6% (+40.3% YoY) | Adobe Analytics, 2025 |
| Social media revenue share, Cyber Monday 2025 | 3.6% (+56.5% YoY, from 2.3%) | Adobe Analytics, 2025 |
| Cyber Monday 2025 online spend | $14.25 billion (+7.1% YoY) | Adobe Analytics, 2025 |
| US 2025 holiday season online spend | $257.8 billion (+6.8% YoY) | Adobe Analytics, 2025 |
| Black Friday 2025 online spend | $11.8 billion (+9.1% YoY) | Adobe Analytics, 2025 |
Context: the Cyber Monday affiliate share (21.8%) runs slightly above the full-season figure (20.4%) because loyalty, cashback, and deal partners over-index on the single highest-discount day.
3. 2025 Performance Benchmarks
The channel got harder to convert in 2025 even as it grew. Affiliate conversion rates fell 6% year over year in 2025, as clicks rose 2% but transactions dropped 5% (impact.com, 2025 Affiliate Benchmark). The offset was basket size: average order value rose 4% to $123 and items per order climbed 8% to 2.5, so shoppers who did convert bought a little more. impact.com’s benchmark draws on 2,368 North American retailers, nearly 1 billion transactions, and over $116 billion in GMV, making it one of the largest same-store affiliate datasets published.
| Metric | Value | Source |
|---|---|---|
| Affiliate conversion rate, 2025 | -6% YoY | impact.com, 2025 Affiliate Benchmark |
| Affiliate clicks, 2025 | +2% YoY | impact.com, 2025 |
| Affiliate transactions, 2025 | -5% YoY | impact.com, 2025 |
| Average order value, 2025 | $123 (+4% YoY, from $118) | impact.com, 2025 |
| Items per order, 2025 | 2.5 (+8% YoY, from 2.3) | impact.com, 2025 |
| Consumer spending through affiliate, 2025 | -1% YoY | impact.com, 2025 |
| Dataset scope | 2,368 retailers, ~1B transactions, $116B GMV | impact.com, 2025 |
Outlier: November clicks jumped 45% year over year while November transactions slipped 1%, the clearest sign of longer research windows before a compressed purchase.
4. Partner Mix and Budget Allocation
Not all partner types pull the same weight, and 2025 widened the spread. Loyalty and rewards partners generated 50% of affiliate transactions from just 33% of brand spend, the highest efficiency of any partner type (impact.com, 2025 Affiliate Benchmark). Influencers and technology partners are the momentum story: influencer transaction volume grew 65% year over year off a small base, and technology-solution conversion rates rose 25%. eMarketer’s spend-side view lines up, showing cashback and loyalty platforms taking the largest slice of dollars. Content-heavy publishers still matter here; our content marketing statistics for 2026 cover that publisher layer in depth.
| Metric | Value | Source |
|---|---|---|
| Loyalty and rewards share of affiliate transactions, 2025 | 50% (from 33% of spend) | impact.com, 2025 Affiliate Benchmark |
| Network partners share of affiliate clicks, 2025 | 45% (up from 41% in 2024) | impact.com, 2025 |
| Influencer transaction volume, 2025 | +65% YoY | impact.com, 2025 |
| Technology-solution conversion rate, 2025 | +25% YoY | impact.com, 2025 |
| Cashback/loyalty/rewards share of US affiliate ad spend, 2024 | 35% | eMarketer, 2025 |
| Discount and coupon share of US affiliate revenues, H1 2025 | 42.4% | eMarketer, 2025 |
| Content publisher share of US affiliate spend, 2024 | 16% | eMarketer, 2025 |
Note: technology partners have climbed from about 5% of budgets in 2021 to roughly 7% in 2024 (eMarketer, 2025), the fastest structural gainer among partner categories.
5. How Brands Invest in the Channel
Survey data confirms affiliate has moved from experiment to core budget line. 74% of brands now generate 11% to 30% of total company revenue from affiliate marketing (impact.com, State of Affiliate Marketing Report 2025), a study of 1,523 respondents across eight countries. Marketers rate the channel highly too: 92% call it effective or highly effective, placing it behind only content marketing and PPC in Awin’s survey. The recurring theme is diversification, with brands treating five partner types on average as important rather than betting on a single publisher category.
| Metric | Value | Source |
|---|---|---|
| Brands generating 11-30% of revenue from affiliate | 74% | impact.com, State of Affiliate Marketing Report 2025 |
| Brands allocating 25%+ of affiliate budget to creators | 59% | impact.com, 2025 |
| Brands experimenting with alternative attribution models | 94% | impact.com, 2025 |
| Marketers rating affiliate effective or highly effective | 92% | Awin/Forrester Affiliate Survey |
| Higher average order value from affiliate-sourced buyers | +21% vs. paid acquisition | Awin/Forrester Survey |
| Marketers citing personalization as a top objective for affiliate | 52% (+26% change) | Awin/Forrester Survey |
Context: impact.com’s survey spanned 818 marketers, 284 publishers, and 421 content creators across the US, Canada, UK, France, Germany, Italy, Australia, and Singapore.
6. Creators, Networks, and the AI Shift
The center of gravity is moving toward creators and automation at the same time. Creator-driven revenue on impact.com surged 51% year over year in 2025 (impact.com, 2025 Momentum Report), and on the Awin network the creator revenue share climbed from 15.9% to 19.5% in a single year (eMarketer, 2025). Amazon Associates remains the largest single program at roughly 46% to 48% of tracked market share, though it cut some publisher commission rates by up to 50% in its 2026 restructuring, pushing creators toward networks with recurring payouts. For the wider picture on creator-led selling, see our influencer marketing statistics for 2026.
| Metric | Value | Source |
|---|---|---|
| Creator-driven revenue growth on impact.com, 2025 | +51% YoY | impact.com, 2025 Momentum Report |
| Active partnerships on impact.com, 2025 | ~350,000 | impact.com, 2025 |
| Creator revenue share on Awin network | 15.9% to 19.5% YoY | eMarketer, 2025 |
| Brands and creators using AI in partnership programs | 97% of brands, 96% of creators | impact.com, 2025 |
| Amazon Associates share of tracked affiliate market | ~46% to 48% | Datanyze; wecantrack, 2025 |
| Amazon publisher commission cuts, 2026 restructuring | up to 50% | Adweek, 2026 |
| Kit (email platform) creators and annual earnings | 600,000+ creators, $2 billion+ per year | Kit, 2025 |
Note: eMarketer found repeated creator collaboration compounds performance, with an eighth YouTube integration reaching 1.8x the affiliate clickthrough rate of the first. Consent-based tooling for creators, from editing suites to voice cloning software, sits alongside these programs; VoxBooster runs a usage-based referral program in the same spirit, though we cite none of our own figures here.
7. Fraud, Attribution, and Measurement
Growth brings adversaries and blind spots. The global invalid-traffic rate across digital advertising reached 20.64% in 2026, based on analysis of 105.7 billion ad impressions (Fraudlogix, 2026 State of Ad Fraud Report), with an estimated $37 billion in US ad spend at risk annually. Affiliate channels are especially exposed to incentivized and bot traffic, and measurement itself is fragmenting as AI assistants intercept the product-research clicks that publishers monetize. That is why 94% of brands are already testing alternative attribution models. Bloggers and review sites remain a large share of legitimate affiliate publishing; our blogging statistics for 2026 break that segment down.
| Metric | Value | Source |
|---|---|---|
| Global invalid-traffic rate, 2026 | 20.64% | Fraudlogix, 2026 State of Ad Fraud Report (via TrafficGuard) |
| US ad spend at risk to invalid traffic annually | ~$37 billion | Fraudlogix, 2026 |
| Global ad fraud losses, 2025 | ~$88 billion, projected $100 billion+ by end of 2026 | Juniper Research (via TrafficGuard), 2025 |
| Brands testing alternative attribution models | 94% | impact.com, 2025 |
| Marketers folding affiliate into general reporting buckets | 27.3% | eMarketer, 2025 |
| Marketers not representing affiliate in reporting at all | 14.8% | eMarketer, 2025 |
Outlier: generative-AI shopping traffic rose 693% year over year during the 2025 US holidays (Adobe Analytics, 2025), the clearest signal that click-based attribution faces a structural test as chatbots answer product questions directly.

Data watch: eMarketer refreshes its US affiliate spending forecast at least twice a year, so 2026 and 2027 figures will be revised; Adobe Analytics publishes its next holiday-season recap in January 2027; impact.com’s Affiliate Benchmark and State of Affiliate Marketing reports run annually, with 2026 editions expected in late 2026 and 2027; Fraudlogix issues its State of Ad Fraud report annually. Some vendor global market-size estimates and older Amazon and network share figures should be read as directional. Where the freshest reliable figure predated 2025, it is flagged inline as most recent available.
