Meta Platforms is set to surpass Alphabet in global digital ad revenue for the first time in history by the end of 2026, according to a new forecast from Emarketer. The research firm expects Meta's net ad revenue to reach $243.46 billion, while Google's is set to stop at $239.54 billion, which would see the crown of the internet's biggest ad machine shift to social networks after more than a decade of search engine dominance.
What makes the difference is the pace of growth. While Google is set to hold steady this year with digital ad revenue growth of around 11.9%, Meta is set to accelerate from 22.1% in 2025 to 24.1% in 2026, according to Emarketer. In absolute terms, that means Meta is adding tens of billions of dollars more each year, allowing it to outspend even a strong player like Google in global advertising.
How Meta is outgrowing Google in advertising
Emarketer explains the change primarily by the difference in growth dynamics. Meta $META 's ad revenue is projected to accelerate from 22.1% this year to 24.1% in 2025, while Google is projected to hold "only" a steady pace of around 11.9%. In absolute terms, Meta is thus adding tens of billions of extra dollars each year, which will allow it to catch up to and even overtake Google $GOOG in net digital ad revenue in 2026, according to projections.
Driven primarily by ad products across Facebook, Instagram, WhatsApp and, more recently, Threads. Meta has launched ads on WhatsApp and Threads, putting it in direct competition with X (formerly Twitter) and other messaging and social platforms, while Reels on Instagram continues to rival TikTok and YouTube Shorts in short video. It is short video and automated campaigns that are one of the fastest growing segments of digital advertising today.
Advantage+ and the concentration of budgets on big players
Playinga significant role in Meta's growth is the Advantage+ suite of tools, which uses machine learning to automate campaigns - from targeting to budget allocation to creative. Emarketer and other analysts point out that it's the ability to deliver higher return on marketing spend (ROAS) with less "manual" work that makes Meta an attractive option for advertisers, especially for midsize and smaller companies without large in-house teams.
At the same time, in an environment of geopolitical uncertainty and budget cuts, ad spend is concentrated towards the largest platforms. Analysts cited by Reuters say smaller players such as Snap $SNAP or Pinterest $PINS are more vulnerable when budgets are cut, while Meta and Google will capture a larger slice of the "shrinking pie" thanks to the scale and power of their ad systems. Emarketer estimates that by 2026, Google, Meta and Amazon combined will already account for roughly 62% of global digital ad spend.
What Google has in addition and why it may still be falling behind
Alphabet has a more diversified business compared to the Met - in addition to search and YouTube advertising, cloud, hardware, YouTube Premium subscriptions and other segments are still growing rapidly. But it's the broader mix that analysts say may be holding back pure ad growth: Google has more "legs", but not all of them are growing as fast as Meta's ad business, which is still essentially primarily an advertising company.
Analyst Max Willens comments that Google's outperformance in ad revenue is a symbolic endorsement for Meta of its strategy - a focus on performance marketing, massive use of AI in targeting and aggressive monetisation of new spaces like Reels, WhatsApp and Threads. Google still has plenty of growth avenues, according to him, but in the pure advertising line, Meta's higher growth rate may put it behind for some time.
What this means for the digital advertising ecosystem
If Emarketer's forecast comes true, it will end an era when it was taken for granted that Google was the "ad leader" of the internet. For the first time in history, the combination of social, short-form video and messaging would generate more ad revenue than search and YouTube combined.
From the advertisers' perspective, this marks another shift to a few dominant platforms that hold most of the reach, data and optimization tools. For medium and smaller networks, this further increases the pressure - in an era where budgets are shifting rather than growing massively, it will be increasingly difficult to carve out a significant share alongside Meta, Google and Amazon's $AMZN.
Why Meta is accelerating: AI, WhatsApp, Threads
Emarketer attributes Meta's accelerating growth to several factors:
Advantage+ and AI automation: automated campaigns boost performance and lower the barrier to entry for advertisers who don't have to deal with complex setups.
WhatsApp and Threads: ads on these apps are estimated to add up to an extra $25 billion a year over the next few years.
Reels and short video: Meta has been able to monetize Reels in a way that no longer dilutes overall margins - tmp has expanded inventory while maintaining strong ROAS.
Google, by contrast, is growing more steadily but more slowly. YouTube is still going strong, but some of the growth is shifting to subscriptions (YouTube Premium) which are not net ad revenue, and experiments with AI answers in search are not yet multiplying ad revenue at the same rate Meta is growing on social.
