TechCrunch / Bloomberg·medium signal

A Bloomberg investigation found that nearly all 20 US state-run health insurance marketplaces shared residents' application data with ad tech companies via misconfigured tracking pixels. Washington D.C. sent applicants' sex and citizenship responses to TikTok; New York shared enrollment pages — including incarcerated family member details — with TikTok, Meta, Snap, and LinkedIn. More than 7 million Americans bought health insurance through these sites in 2026. Virginia and D.C. paused data sharing after the investigation; the rest have not responded.
