Meta Platforms is on track to surpass Google in global digital advertising revenue this year, signalling the most significant shift in industry leadership in nearly two decades.

According to eMarketer, Meta’s ad revenue is projected to hit $243.46 billion in 2026, narrowly ahead of Google’s expected $239.54 billion. The growth trajectory is equally striking, with Meta forecast to expand by 24.1% this year, outpacing its long-time rival.

That surge has been fuelled by sustained advertiser demand across Facebook, Instagram and WhatsApp, alongside an aggressive push into artificial intelligence. Meta has invested heavily in AI-driven tools that refine ad targeting and simplify campaign management, making its platforms more accessible to both global brands and small businesses. The impact has been reflected in consistent quarterly revenue gains.

Instagram Reels has emerged as a major growth engine, capturing user attention and attracting advertising budgets that might previously have been directed elsewhere.

Chief executive Mark Zuckerberg has outlined a future where advertising becomes largely automated. In his vision, businesses would simply input a budget and objective, while AI handles the rest a transformation Meta suggests could materialise as early as the end of 2026. Such a shift is expected to lower barriers for smaller advertisers, expanding the overall pool of businesses spending on its platforms.

Despite the momentum, Google remains a formidable competitor. Its advertising ecosystem spans Search, YouTube, Maps and a vast network of partner sites, giving it unmatched reach across intent, content and commerce.

The company surpassed $400 billion in annual revenue in 2025, with ad revenue continuing to grow strongly.

Google is also evolving its own model, integrating advertising into AI-powered search experiences and introducing new formats within AI-generated responses; a move aimed at unlocking fresh monetisation opportunities.
Still, the balance of power is shifting. For years, Google’s dominance at the top of digital advertising went largely unchallenged. Now, with Meta closing in, that assumption is being tested for the first time in a generation.
