Here’s the latest from the Paragon Health Institute:

Our research demonstrates that improper enrollment remains deeply embedded within the ACA exchanges and that structural vulnerabilities continue to create incentives for improper enrollment…

We estimate that approximately 6.2 million exchange sign-ups in 2026 were improper, representing roughly 27 percent of all ACA exchange sign-ups, the same percentage level as after 2025 open enrollment. We project taxpayers will fund up to $25 billion in improper subsidy payments in 2026 – nearly one-quarter of projected ACA subsidy spending in 2026.

That’s more than the entire population of Minnesota.
