Social Media Ad Spend Climbs as Meta Closes In on Google in 2026

The short version

In mid-October 2026, social advertising is still the fastest-growing major part of the digital ad market, and Meta is collecting most of the gains. Forecasters agree on the direction. They disagree, sometimes widely, on the size of the market. Meanwhile influencer budgets keep growing, and ad platforms keep taking manual controls away from the advertisers who pay them. Taken together, the coverage points to a market that is growing quickly and concentrating at the same time, with cost and measurement problems underneath that the headline figures don't show.

Meta's numbers set the tone

Meta's most recent quarterly results are the starting point for the rest of the market. Its Q2 2026 advertising revenue rose 27% to $59.36 billion, up from $46.56 billion a year earlier.11 Two levers drove the gain. Ad impressions grew 14% year over year, and the average price per ad rose 12%.11 Meta also said its AI-run Advantage+ campaigns have passed a $75 billion annual revenue run rate.18 That figure helps explain why the company keeps pushing advertisers toward automated buying.

Forecasters expect Meta to change the industry rankings this year. An eMarketer forecast projects $243.46 billion in Meta ad revenue for 2026, or 26.8% of global ad spending. That would put Meta just ahead of Google's projected $239.54 billion.14 Meta has never led Google in the 14 years eMarketer has tracked the market.15 WARC's own model puts Meta's 2026 total near $240 billion.14 Q3 earnings, due in late October, will be the next real test of that forecast.11

The headline figures leave some things out. One quarterly analysis notes that Meta's daily active people fell to 3.56 billion in Q1 2026, the first sequential decline in the company's history. Over the same period, Meta raised its 2026 capital-spending guidance to $125–145 billion.20 Revenue growth that relies on higher prices while the user base stays flat is a different business from one driven by audience growth. Advertisers are already feeling the difference.

Spending more, getting less

One agency's October roundup puts it bluntly. It reports that ad spending on Meta's platforms is up 47%, while average cost per lead across Meta has risen 14% to about $6.34 The same report says Meta will start charging businesses for posting links to followers.34 eCommerce benchmarks point the same way. Median Meta CPMs rose about 20% in 2025 to $14.19, and median return on ad spend was 1.86.15

This is a key point. Meta's record revenue and advertisers' falling returns are the same thing seen from opposite sides: more competition in Meta's auction means higher prices for buyers. Meta's own figures show price per ad rising almost as fast as impressions, which suggests demand for Meta's ad space is growing faster than the supply.11

Social now leads US digital advertising

At the market level, the shift toward social is large. The IAB/PwC full-year report puts US social media ad revenue at $117.7 billion in 2025, up 32.6%. Total US digital ad revenue grew 13.9% to $294.6 billion, so social grew more than twice as fast.12 One analysis says this put US social ad revenue ahead of search for the first time.14 In September the IAB raised its 2026 US growth outlook from 9.5% to 12.3%, led by social media at 16.5% and connected TV at 15.6%.24

Social's share of global spending is rising too. WARC expects social to take about a quarter of all global ad spending in 2026, which would be a first, and forecasts global social ad spend above $300 billion.15 WPP Media expects "social and other digital" to grow 16.3% this year to $161.4 billion. It credits AI-driven ad delivery, short-form video and creator-led distribution.23

Smaller platforms are growing fast, but their revenue is small next to Meta's. Reddit's ad sales rose 64% in Q2 to $762 million, Snap's total revenue rose 19%, and Pinterest's rose 18%. Combined, Pinterest, Snap and Reddit brought in about $3.5 billion that quarter, compared with Meta's $59.36 billion.14

TikTok: growth is clear, the size isn't

TikTok shows how far apart the estimates can be. WARC puts TikTok's 2026 global ad revenue at $34.8 billion.15 Another widely shared estimate puts it at $43.96 billion, a 33% increase.16 Estimates for TikTok's US business vary even more: $13.7 billion, $14.5 billion and more than $17 billion, depending on the source.171915

The direction is consistent across estimates, though. eMarketer projects that TikTok's share of combined Meta and TikTok ad spending will rise to 25.7% in 2026 from 23.6%.12 Even so, an analysis of more than 44,000 advertisers found that 91% run ads on Meta alone, compared with 5% on TikTok alone.12 TikTok is gaining share, but Meta is still where most advertisers start.

Influencer budgets keep growing

Creator marketing is where advertisers are expanding fastest. eMarketer figures, cited in several reports, put US influencer marketing spend at $10.52 billion in 2025. They project 15.7% growth to $12.17 billion in 2026 and $13.7 billion by 2027.36 eMarketer also tracks a broader "creator marketing" measure that includes retail media and connected TV. It raised that measure to $21.10 billion for 2026 in February.67

Brand surveys show strong intent to spend more. In Influencer Marketing Hub's 2026 benchmark, 87.49% of brands expected their influencer budgets to rise, and only 5.55% expected cuts.3 Aspire found that brands put an average of 23% of their marketing budgets into creator partnerships last year, and that 74% planned to increase that share.1 Another analysis puts creators' median share of social budgets at 26%, up from 18% in 2024.4

Global market-size figures are less consistent. One summary gives a 2026 range of $34.1 billion to $38.7 billion.8 Another cites forecasts as high as $40.51 billion to $47.8 billion.2 At least one source still uses an older US spending estimate of $9.29 billion.5 These numbers measure different things, so readers should treat the US eMarketer series as the most reliable reference and the global totals as rough estimates.

The tools behind creator marketing are changing quickly. This week CreatorIQ launched Q, an AI agent system for enterprise creator marketing. It came with MeasureIQ for performance metrics and an upgraded SafeIQ that scans videos for brand-safety risks.33 CreatorIQ says SafeIQ cuts manual review from about 40 minutes per video to about one minute.39 Brand-safety concerns are real: a Kantar and IZEA study found that 76% of brands are worried about fake influencers, as AI-generated synthetic profiles have surged.7

Forecasters disagree on the global total

The biggest gap is in estimates of the total ad market. WPP Media's midyear forecast is widely reported as projecting 8.9% global growth to $1.3 trillion, excluding US political spending, up from 7.1% in December.2327 WPP Media's own summary, however, cites 5.1% growth to $1.3 trillion.21 One trade outlet reported the same forecast as 4.4%.29 Other forecasts range from dentsu's $1.06 trillion to Madison and Wall's $1.42 trillion, a gap of about $360 billion for the same year.24 Much of that gap reflects different definitions of what counts as ad spending.22

The forecasts do agree on several points. The US is growing faster than the global average, at about 11.9% by WPP Media's count.27 Alphabet, Amazon and Meta are taking a growing share: WARC expects their combined share of ad spending outside China to reach 58.0% this year.22 And AI investment is supporting ad spending despite geopolitical and economic pressure.28

The most important forecast for social platforms may be WPP Media's longer-term view. It expects social's growth to slow to single digits from 2027. It names three reasons: time spent on social platforms is leveling off or falling, age-based access restrictions are spreading, and AI chatbots are competing for users' time.21 Generative search advertising is tiny today, at about $5.1 billion in 2026, but WPP Media projects it will pass $100 billion by 2030.23

Advertisers are losing control

This week's operational news follows the same pattern. As of October 1, Microsoft Advertising no longer lets advertisers set a maximum cost per click on new campaigns that use several automated bidding strategies.31 Google is moving older Search campaign features into AI Max and retiring standalone Display campaigns.32 The FTC and 22 states have sued Amazon, alleging that its ad auction charged advertisers more than real competition would have.32 Early ChatGPT advertisers report very different costs per click, from under $3 to $10–$13.32

Our view

The evidence supports a clear conclusion. Social advertising in 2026 is growing quickly and concentrating in a few companies, and much of the growth comes from higher prices rather than more value for advertisers. Meta's 27% growth, the shift toward creators and record ad-market totals are all real. So are rising cost per lead, the disappearing bid controls, and forecasts that differ by hundreds of billions of dollars. The next tests are Meta's Q3 results and whether WPP Media's expected slowdown in 2027 begins to show. Until then, advertisers should treat strong platform revenue as a sign of demand for ad space, not as evidence that their own campaigns are working.
