Meta Platforms is projected to surpass Alphabet's Google in digital advertising revenue globally by the end of 2026. The Instagram-owner's global net ad revenues are expected to reach $243.46 billion, ahead of Google's projected $239.54 billion. Meta's Advantage+ automated ad suite has seen strong advertiser adoption. "In surpassing Google, Meta has essentially had many of its core strategies validated," said Emarketer analyst Max Willens.

While Google has other growth avenues, its broader business mix could make it harder to outpace Meta in ad revenue. Smaller platforms like Snap and Pinterest remain most exposed to ad budget cuts during geopolitical uncertainty, as spending concentrates on larger platforms such as Meta and Google.

The driving force behind the change is Meta's accelerated growth rate, forecast to increase to 24.1 percent this year, from 22.1 percent in 2025. Google's growth rate is expected to remain steady at 11.9 percent this year.

Meta intensified competition by launching ads on WhatsApp and Threads, directly rivaling platforms like Elon Musk's X. Instagram's Reels also continues to compete with TikTok and YouTube Shorts in the short-video market. Google, Meta, and Amazon are projected to account for 62.3 percent of global digital ad spending in 2026. Recent court rulings against Meta and YouTube are not expected to materially impact this forecast.
