Author: Bill Ross | Published: January 19, 2026 | Updated: May 24, 2026 Partnership and co-marketing campaign trends in 2026 favor brands that treat partner ecosystems as core revenue infrastructure, not a side channel. Affiliate, creator, and co-branded programs are absorbing budget that once went to paid social and search, and the ROI gap between top-tier partnership programs and standard display advertising has widened to a 6x multiple. The brands winning right now share three traits: they invest in measurement, they prefer rosters of smaller creators over single celebrity buys, and they design partnerships for long-term ambassadorship rather than one-off drops. Key takeaways from this report: Three out of four U.S. marketers are putting more money into creator and partner marketing this year. The growth is not coming from new entrants alone; established brands are reallocating dollars away from paid social and search and toward performance-based partner channels with cleaner attribution. The cut-rate is the more telling number. With only 5.5% of marketing teams planning to spend less on partnerships in 2026, the channel has cleared the threshold where finance teams treat it as discretionary. Budget direction is the cleanest leading indicator of channel maturity, and partnerships are no longer in the experimental column. That confidence shows up in dollar terms too. U.S. affiliate and partner-program spend has nearly doubled from $6.2 billion in 2018 to about $12 billion in 2025, and the trajectory points to $15.8 billion by 2028. The slope of that curve is starting to bend, which is what an S-curve does as a channel matures. Annual growth has slowed from the 14% to 18% range seen between 2019 and 2022 to roughly 13% in 2024-25, and we expect about 9% growth by 2028 as the channel competes for share with retail media networks and creator-led commerce. The dollars keep coming, but the easy gains are behind us.
“The brands moving fastest in 2026 stopped treating partnership marketing as a category and started treating it as a category of categories. Affiliate, creator, ambassador, co-branded launches, channel reseller programs, and influencer commerce each need their own measurement model and their own owner.” – Strategy Team, Emulent
That budget confidence sets up the next question: where is the growth actually happening, and how long does it last? The answer points to the creator economy, which has done most of the heavy lifting so far. Brand-creator partnerships went from a $1.7 billion experiment in 2016 to a $32.55 billion global channel by the end of 2025, a 19x expansion in under a decade. The compound annual growth rate over that span runs at roughly 33%, which is the kind of curve you typically only see in early-stage technology adoption. The line keeps climbing, but the slope flattens. We model 25% growth in 2026 and roughly 15% by 2028 because three things are pulling against the curve: 86% of U.S. marketers at large companies already run a creator program, audience attention has finite ceilings, and connected TV plus retail media are competing aggressively for the same incremental budget dollar. The shift inside the channel matters more than the headline number. Long-term ambassador deals are replacing one-off sponsored posts. According to Influencer Marketing Hub, 73% of marketers plan to invest in ongoing creator partnerships rather than single-campaign deals, and 47% of brands already prefer recurring relationships over one-off drops. The economics favor durability: ambassador deals build cumulative trust with the audience and amortize creative production costs across multiple touchpoints. For brands that have built their strategy around social media advertising as the primary growth lever, the implication is that the same dollar produces more lift when it flows through a creator with audience equity than when it powers a one-time paid social burst. That shift is being absorbed unevenly, which is why the gap between ecosystem leaders and everyone else has gotten wider. Across the B2B landscape, partnership revenue share spreads across a wide range. The leaders look almost nothing like the median. Microsoft sources 95% of revenue through partners. Shopify, ServiceNow, and other ecosystem leaders sit around 65%. The top-quartile B2B performers in PartnerStack and Crossbeam data come in at 58%. Then there is a steep cliff: mature programs average 28%, the median B2B firm with any partner program sits at 22%, and companies without a formal program capture less than 5% through partners. Three-quarters of global B2B transactions now flow through channel partners, but most companies are not capturing their fair share of that volume. The gap traces back to enablement. Only 28% of partner programs include formal certification pathways, and Forrester reports that certified partners generate roughly 6x the revenue of non-certified peers. The leaders are not winning because they have better partners. They are winning because they have built training infrastructure, attribution systems, and dedicated partner enablement teams. For companies serious about B2B marketing services, the implication is direct: budget for partner enablement carries higher marginal returns than another paid media test.
“When we audit B2B partnership programs, the strongest predictor of revenue contribution is not the size of the partner network. It is whether someone in the company owns partner enablement as a job rather than a quarterly initiative. Programs without a named owner regress to the bottom tier within 18 months.” – Strategy Team, Emulent
Forrester data shows 67% of B2B ecosystem leaders expect indirect revenue growth above 30% in 2025. That is not gradual improvement; it is compounding separation. The companies that miss this window will spend the rest of the decade trying to catch a moving target. Once you understand the structural gap, the next question is which type of partner actually drives the engagement that closes it. The follower-count assumption that ruled influencer marketing through 2020 has been quietly inverted. Smaller creators carry the engagement load now, and the math is reshaping how brands build their partner rosters. On Instagram, nano creators with audiences between 1,000 and 10,000 followers post an average engagement rate of 6.2%. Mega creators with more than a million followers average 1.0%. That is a 6.2x gap on a per-post basis, before accounting for cost. On TikTok the spread is even sharper: nano creators on the platform hit a 10.3% engagement rate, the highest of any tier on any major platform. The behavioral explanation is straightforward. Smaller creators retain something close to parasocial intimacy with their audience, and their content shows up in feeds that have not been algorithmically diluted by celebrity-tier follower noise. As follower counts grow, the trust premium decays and the algorithm tends to distribute content less efficiently to the long tail of casual followers. What this changes for roster construction: Roughly 40% of total influencer marketing budget already flows to micro-influencers, and that allocation continues to grow. The reallocation is not a fad. It is the channel converging on its economically optimal structure. For brands rebuilding their brand strategy around partnership, the choice between five mega-partners and fifty micro-partners has a clearer answer than it did three years ago. Of course, none of this matters if a brand cannot prove the partnerships actually pay back. That brings us to the ROI question, which is where partnership marketing earns or loses its budget defense. Partnership ROI sits at a different altitude than digital display advertising, but the spread between top and median performance is wider than most marketing teams realize. Best-in-class affiliate programs return $15 per dollar spent. Top-decile influencer campaigns clear $14.50. The average creator partnership returns $5.78, a typical co-branded campaign launch hits $3.00 within 90 days, and the display advertising baseline sits at $2.50. The top of the chart represents real performance, but it requires real infrastructure: clean first-party attribution, performance-based compensation, and creator selection that matches audience to product fit. The honest forecast is that this spread compresses over the next three years. As more brands enter the channel, attribution improves, and AI-driven measurement tightens the gap between disciplined and undisciplined programs, the top of the chart drifts down toward the median. Mean reversion is real, and brands building their case for partnership budget should plan for it.
“The brands quoting $15-to-$1 ROI in their 2026 planning decks are pointing at the ceiling, not the median. We tell clients to plan their budget against the average creator partnership return of $5.78 and treat anything above that as outperformance they have to earn through measurement discipline.” – Strategy Team, Emulent
For marketers running franchise marketing or multi-location programs, partnership ROI is particularly attractive because creator audiences map naturally to local trade areas. A nano creator in Charlotte produces engagement that geo-targeted display rarely matches at the same cost. The same logic applies to small business marketing where the partner channel can substitute for paid media budgets that simply cannot compete with national advertisers on CPM. The numbers make the case for the channel. The harder question is what marketing teams should actually do with this information in the short term. The data points in one direction, but the implementation work is where most programs stall. The teams getting traction in 2026 share a tighter operating discipline. Concrete actions for marketing teams entering the next quarter:
“In every partnership audit we run, the same finding shows up: the top three partners deserve 5x the investment they currently receive, and the bottom 50% should be quietly retired. Marketers know this. What stops them is that pruning a partner network is harder politically than adding to it. The teams that win are the ones who do the pruning anyway.” – Strategy Team, Emulent
For companies modeling partnership against other 2026 growth channels, our B2B marketing trends coverage and the broader digital marketing industry projections provide useful sibling context. The partnership story does not exist in isolation; it is part of a wider rebalancing in how marketing budgets allocate against the post-cookie attribution environment. Partnership marketing rewards the brands that take it seriously enough to build infrastructure around it. The agencies that helped clients with paid social for the past decade are not always equipped to build a partner program, run an affiliate audit, or design a creator ambassador roster with attribution that survives finance scrutiny. We work with B2B and consumer brands to build that infrastructure end-to-end: program design, partner recruitment, enablement content, attribution architecture, and the ongoing optimization work that keeps a partnership program in the top quartile. If you are building or rebuilding a partnership marketing program, or you want a clear-eyed audit of what your current creator and affiliate spend actually returns, the Emulent team can help.
