Sports brands are diversifying their advertising media mix quickly, and new Sensor Tower research shows the scale.
By channel
| Channel | Change |
|---|
| YouTube, TikTok, Instagram, Facebook (Q2) | +25% YoY |
| Mobile app spend | +116% |
| Digital overall (50+ markets, 18 channels) | USD 3.3B, +26% YoY |
| Linear TV (Q3 2025–Q2 2026) | Over USD 500M, +2.3% YoY |
| Ad impressions | +11.2% YoY |
The half-billion-plus on linear TV came from advertisers spanning gaming, entertainment and wagering.
One contrast stands out: spend rose 26% while impressions rose only 11.2%. Sensor Tower reads that as investment moving toward higher-cost inventory.
Prediction markets scaled hard
Month-over-month digital spend increases during the tournament:
- Kalshi — +104%
- Polymarket — +286%
A marker of how large sports betting and prediction market brands are becoming in this landscape.
Sportsbook concentration by property
Share of all ad impressions from sportsbook advertisers, H2 2025 through H1 2026:
| Property | Sportsbook share |
|---|
| NBA | 26% |
| MLB season | 15% |
| Super Bowl | 13% |
The NBA is highest. March Madness shows a more balanced mix, with food and dining taking 16% of ad impressions.
What marketers should take
Media mix diversification is now the default in sports marketing. Linear TV is not dead (+2.3%), but the growth is going to digital and mobile apps.
Cost per impression is rising. A 26% spend increase against 11.2% impression growth means the same budget buys less. Event-season budgets should be built around inventory quality, not volume.
Competitive density varies by property. Where one category holds 26% of impressions, as with the NBA, differentiation costs more for brands in that category. More balanced properties leave room to enter.
