Health and Government Organizations Spend Millions Advertising on Misinformation Websites

Apr 5, 2026

A CNN investigation reveals that health and government organizations spent $35.7 million on advertising across 11 websites promoting health misinformation between 2021 and 2024, accounting for over 10% of these sites' ad revenue. The American Heart Association and Alzheimer's Association each spent less than $25,000 annually on such placements, which they attribute to unintentional consequences of automated advertising systems that lack full visibility into site placements. The US Department of Health and Human Services also placed ads on misinformation sites, though the agency now emphasizes its commitment to evidence-based science under Kennedy's leadership. Yale University researchers partnered with NewsGuard to identify the problematic websites, finding that nonprescription wellness products represented the largest advertising category at over $19 million in spending.
