30+ Advertising Statistics: Global Spend, Digital Share & ROI (2026)

Advertising in 2026 is no longer an industry. It is a tax on attention, collected in dozens of currencies across hundreds of platforms, and added up at the end of each quarter by a small group of forecasting houses that almost never quite agree with each other. GroupM, Magna, Dentsu, WARC and the IAB will each publish their own version of the truth. The headline they all converge on is the same: global ad spend will clear the trillion-dollar mark in 2026, digital will take roughly three out of every four dollars, and a small handful of US technology companies will collect most of the digital share.

For a deal-driven site like 99coupons.ai, ad spend statistics are not a vanity metric. They explain why retail brands keep pushing promo codes through creators, why Amazon Ads and Walmart Connect are eating into Google and Meta's growth, why connected TV inventory is finally starting to convert, and why every retailer with a logged-in audience now considers itself a media company. Below are 30+ statistics we could verify against their primary sources for 2026, organized into eight themes that matter for any advertiser, publisher or shopper trying to make sense of where the money actually goes.

Global Ad Spend in 2026

1. Global ad spend will reach $1.1 trillion in 2026.

GroupM's December 2025 This Year Next Year forecast projects global advertising revenue at roughly $1.1 trillion in 2026, growing 7.7% year over year, after closing 2025 at $1.03 trillion.
