A Bloomberg investigation published on 2026-05-04 found that almost all of the 20 U.S. state government-run health insurance marketplaces shared residents’ application information with advertising and tech companies including Google, LinkedIn, Meta and Snap. [1]
The reporting said New York’s health insurance exchange shared sensitive application details, including whether a person had incarcerated family members, with several tech companies. [1]
In Washington, D.C., the exchange shared residents’ sex, race, email address, phone number and country identifiers with TikTok. TikTok’s pixel tracker also tried to redact some race information, according to the report. [1]
After the Bloomberg report, Washington, D.C. paused the rollout of the TikTok tracker on its health insurance exchange website. Virginia also removed the Meta tracker from its exchange site after it was found sharing ZIP codes with Meta. [1]
The exchanges sit at the center of a large enrollment pool. More than 7 million Americans bought health insurance through state exchanges in 2026, according to the report. [1]
The investigation covered 20 state marketplaces and found the sharing practice was widespread across the government-run sites. [1]
