The advertising sector powers into 2026 with forecasts signaling sustained expansion, propelled by digital platforms amid economic headwinds and technological upheaval. WPP Media’s This Year Next Year report projects global ad revenue climbing 7.1% to over $1.22 trillion, excluding U.S. political spending, after an 8.8% surge to $1.14 trillion in 2025. This upward revision stems from milder tariff effects and surging AI investments, outstripping broader GDP growth.
In the U.S., the paramount market, Madison & Wall forecasts 6.6% growth sans political ads—or 8.9% inclusive—building on 2025’s 11% rise, as detailed in their update. WPP aligns with 7.6% North American growth, boosted by the Winter Olympics, FIFA World Cup, and midterms injecting $12.3 billion in political outlays. Resilient consumer patterns and performance-focused tactics underpin this vigor, even as budgets pivot sharply digital.
AI-fueled tech sectors and e-commerce integration amplify momentum, yet tariff ambiguities and potential pharma ad curbs loom as risks. WPP’s Kate Scott-Dawkins highlights an industry in ‘creative destruction,’ with algorithms reshaping consumer-brand ties.
Digital Channels Claim Incremental Gains
Digital formats will seize over 83% of global spend, per WPP, with programmatic, retail media, social, search, and connected TV (CTV) spearheading advances. Retail media eclipsed total TV in 2025, eyeing $190 billion in 2026, led by Amazon and Walmart’s high-intent ecosystems, as noted in Adweek.
Search endures AI pressures, with mid-single-digit growth anticipated through the decade; WPP pegs it at $244.9 billion in 2025, stable into 2026. Social and short-form video leverage AI optimization, while programmatic surges: digital out-of-home and audio up 30%, open CTV inventory 26%, fueling 4.4% overall lift, according to Madison & Wall via Digiday.
Precision targeting and e-commerce ties siphon funds from rigid mediums, with CTV maturing via shoppable formats and data clean rooms. Retailers extend first-party signals into streaming, converting passive views to sales, as eMarketer projects U.S. retail media at $69.33 billion in 2026.
Tech Titans Fortify Ad Supremacy
Alphabet, Meta, and Amazon command over half of digital revenue, with Google dominating search, Meta social feeds, and Amazon retail surges at 16% U.S. growth. Their AI prowess and data troves erect barriers, yet spark efficiency for buyers. Apple eyes $30 billion by 2026, per EvercoreISI via X post by Patrick McGee.
Concentration fuels diversification worries but powers innovation; top 25 sellers snag 70% revenue, per WPP. Agencies counter via adtech buys and proprietary AI, per Strategies on X.
Programmatic CTV hits $33 billion in 2025, with interactive ads at 10% of inventory converting 5x better, signaling performance evolution, as DemandLocal reports.
Linear TV Clings to Stability Amid Erosion
Total TV holds at $170.8 billion in 2026 (+2.1%), but linear plunges 2.6% to $120.3 billion, per WPP. Madison & Wall flags Q3 2025 double-digit national/local drops, with overall TV down 4.4%. Challenges mount: streaming fatigue, sports rights fleeing to tech, and SMBs favoring Google/Meta accessibility.
WPP poses pivotal queries: Can streaming sustain amid fatigue? Will broadcasters retain sports viability? WARC forecasts global linear at $139.1 billion in 2026, down 11%—lowest since 2005—as CTV rises 3.6% to $44.7 billion.
Pharma shifts from linear, with digital outpacing traditional 4:1 by 2026, per FiercePharma citing eMarketer.
Key Events and Cyclical Boosts
Midterms propel $10.8 billion political spend, per AdImpact, with CTV claiming $2.5 billion. Olympics and World Cup amplify, yet core OTA dips as funds flow to CTV/digital, BIA notes. Political surges pressure small biz, sparking ‘Ad-pocalypse’ pivots to email/SMS, per Creative Shift on X.
U.S. total hits $490.9 billion (+9.1% incl. political), WPP projects. Local TV eyes 25.5% jump to $18.18 billion, but non-political erodes.
Marketers eye AI literacy, commerce ties, and metrics; reallocating from linear to retail/CTV/programmatic proves vital. Digital-first agility defines victors in this reinvention.
Strategic Imperatives for Marketers
Mediaocean survey via Clare Advisors on X shows display/video/social priorities over AI/influencers; traditional/print decline, CTV ascends. CTV demands omnichannel integration, per AdExchanger, with 100% ad reach via Roku.
Programmatic waste at 64% mandates verification; agentic AI and trust rise, Basis roundtable warns. Brands blending AI precision with authenticity scale, per Olly Hudson’s 2026 playbook on X.
