Brands spent around US$10.5 billion on the 2026 World Cup, but online betting made up just 2% of ad impressions. The sports marketplace is diversifying, and attention is up for grabs by more categories than ever.
The 2026 FIFA World Cup pulled in a spending spree, with brands committing around 10.5 billion US dollars globally and US advertising alone estimated near 850 million. But the more interesting number is a small one. Despite betting platforms Kalshi and Polymarket throwing money around at record levels, online betting accounted for just 2% of ad impressions during the tournament.
That gap tells a story. The prediction markets had a monster event, Kalshi cleared more than 30 billion dollars in trading volume in June alone, yet the advertising airwaves were not dominated by gambling. The spend spread across a far wider mix of categories than the sports marketplace of a few years ago.
Why it matters
Big sporting moments still drive spend, but the assumption that a handful of usual-suspect categories own them is breaking down. The marketplace is diversifying. New money is coming in from prediction markets, from brands that never used to play in sport, and the impression share is spreading out rather than concentrating. For a marketer, that means both more competition for attention and more room for a brand that shows up cleverly rather than just loudly.

What to do about it
Attention at a global event is up for grabs by more categories than ever. That is a threat and an opening at the same time.
