Colorado: Q1 effectuated enrollment down 5.3% y/y; could drop by up to 9.1% or more by end of 2026
Connect for Health Colorado, the state's ACA exchange, has published effectuated enrollment data for January, February and March 2026, so it's time to dig in and see what this might say about national trends. Unfortunately, it doesn't provide much demographic data (metal levels, income levels, etc), but it does at least provide the number of effectuated enrollees as well as new and terminated enrollments. Below is what it looks like compared to the same months in prior years. I'm disregarding the COVID years (2020 - 2023) but am including 2016 - 2019 (none of which included the enhanced federal tax credits) as well as 2024 & 2025. Officially, Qualified Health Plan (QHP) selections during Open Enrollment were only 1.9% lower than they were in 2025. However, as I expected and have warned about repeatedly, the year over year drop in effectuated enrollment was double that in January (3.8%), and the gap grew in both February and March. For the first quarter of 2026, effectuated enrollment in Colorado is down 5.3% vs Q1 2025. What might this look like for the rest of the year?
