Spain’s CTV market reaches 95% penetration, trust still lags
A 2026 study by IAB Spain reveals that Spain's Connected TV (CTV) market has reached 95% penetration with 34.3 million users and 175 million euros in ad spend. Despite high penetration, the study highlights a trust gap in CTV advertising due to measurement challenges, which is hindering advertiser confidence.
Key Takeaways
- IAB Spain’s 2026 CTV study puts the market at 34.3 million users.
- CTV ad spend in Spain reached 175 million euros, according to the study.
- Market penetration has hit 95%, but measurement gaps are still limiting advertiser confidence.
- The study frames trust in CTV advertising as an unresolved issue, despite near-universal reach.

What to watch next is whether Spain’s CTV ad market can close the measurement gap enough to convert 95% penetration into higher advertiser trust.
