Social Media Sites Got Information from Ad Trackers on US State Health Insurance Sites

All 20 of America’s state-run healthcare marketplace sites “include advertising trackers that share information with Big Tech companies,” reports Gizmodo, citing a report from Bloomberg:

Per the report, seven million Americans bought their health insurance through state exchanges in 2026, and many of them may have had personal information shared with companies, including Meta, TikTok, Snap, Google, Nextdoor, and LinkedIn, among others. Some of the data collected and shared with those companies included ZIP codes, a person’s sex and citizenship status, and race.

In addition to potentially sensitive biographical details about a person, the trackers also may reveal additional details about their life based on the sites they visit. For instance, Bloomberg found trackers on Medicaid-related web pages in Rhode Island, which could reveal information about a person’s financial status and need for assistance. In Maryland, a Spanish-language page titled “Good News for Noncitizen Pregnant Marylanders” and a page designed to help DACA recipients navigate their healthcare options were found to be transmitting data to Big Tech firms…

Per Bloomberg, several states have already removed some trackers from their exchange websites following the report.
