World Cup Gives U.S. Ad Market Its Best Month Of 2026.

The U.S. ad market roared into summer with a 19.3% increase in total spending during June compared to a year earlier. The latest update from Guideline’s SMI Ad Tracker shows it was easily the best monthly performance of the year as World Cup-related marketing kicked into high gear. June’s growth marks six consecutive months of year-over-year increases in ad spending.

Guideline says overall traditional media advertising spending jumped 26% in June from a year earlier. The vast majority of those World Cup fueled marketing dollars went into national television where spending rose by more than a third (+36%) year-over-year.

Digital spending was still up, rising 17% from a year earlier. Even so, digital’s share of the ad market was down five points from the prior month as it accounted for 72% of total U.S. ad spending in June compared to a 28% share for traditional media.

Guideline Chief Insights and Analytics Officer Sean Wright says on his “Media Monitors” podcast that their data shows about 75% of World Cup dollars were spent on broadcast TV compared to 25% for streaming. That compares to a 95% share for broadcast TV during the Qatari World Cup four years ago. Wright predicts the two could be evenly split in 2030, particularly if additional streaming services secure broadcast rights.

With several large marketers tied to the World Cup, Guideline reports ad spending among the top 10 product categories rose 19% in June from a year earlier. But all other product categories were also up 19%, suggesting brands didn’t need to be officially tied to FIFA in order to embrace the buzz.

First Half Spending Up

Even with the Winter Olympics, World Cup and other major events filling the 2026 calendar, the first half didn't deliver the kind of growth Wright had been expecting. Still, he sees no sign of a pullback and points to several bright spots that could help stabilize the market as the year progresses.

Guideline reports says total U.S. advertising spending increased about 4% during the first six months of the year. That's well below the roughly 10% growth historically associated with years featuring events like the Olympics and World Cup. Strip away the incremental spending tied to those, and Wright estimates the underlying advertising market expanded by 2.8% in the first half.

One of the biggest drags on the advertising market continues to be the auto industry. Wright says automakers kept pulling back on advertising during the first half, and he doesn't expect that trend to reverse anytime soon. He attributes the slowdown largely to broader economic pressures and changing consumer behavior, as higher prices and economic uncertainty continue

"Auto continues to really hurt. Even with tentpoles, we're seeing it decline, and we expect that to continue,” Wright says. “Consumers remain cautious about big-ticket purchases.”

Yet not every segment is struggling. Social media advertising also remains one of the strongest performers, growing roughly 14% during the first half, while CTV continues to attract larger shares of media budgets despite difficult year-over-year comparisons. Out-of-home advertising also continues to outperform much of traditional media, benefiting from digital billboards, precise geographic targeting and strong demand from sports betting advertisers expanding into newly legalized markets.

Looking ahead, Guideline expects the second half to remain challenging. Wright says political advertising will provide a meaningful boost, but historically election spending works best when layered on top of an already healthy advertising market. "I expect the slowdown continuing into the second half," he predicts, pointing to inflation and cautious consumer spending weighing on advertiser confidence.
