Data Accuracy Gaps Exposed in New CTV Advertising Report

A new report from Truthset is raising concerns about the reliability of the data signals powering CTV advertising, pointing to significant disparities in accuracy rates across commonly used identity and demographic matches.

According to The State of Data Accuracy 2026, the company estimates that $7.4 billion in U.S. CTV programmatic ad spend will be wasted this year due to flawed or misaligned signals.

  • IP to postal match: 13% accuracy
  • Presence of children: 41% accuracy
  • Age: 13% accuracy
