The Centers for Medicare & Medicaid Services (CMS) reports that nearly 950,000 consumers who do not currently have health care coverage through plans in the individual market Marketplace have signed up for coverage in 2026, since the start of the Marketplace Open Enrollment Period (OEP) on November 1, 2025. Existing consumers are also returning to the Marketplace to actively renew their coverage, and anyone who does not actively renew will be automatically re-enrolled for 2026. Over 4.8 million existing consumers have already returned to the Marketplace to select a plan for 2026.

As usual, I'll start out with the top line numbers, compared to the same point last year:
On Monday I noted that around 20 state-based ACA exchange websites had launched 2026 Open Enrollment "window shopping," which allows residents to plug in their household information (zip code, ages, income, etc) and browse the various health insurance policies they have to choose from for coverage starting January 1st...as well as whatever federal (and state, in some cases) tax credits they'll be eligible for.
The Affordable Care Act includes a long list of codified instructions about what's required under the law. However, like any major piece of legislation, many of the specific details are left up to the agency responsible for implementing the law.
While the PPACA is itself a lengthy document, it would have to be several times longer yet in order to cover every conceivable detail involved in operating the ACA exchanges, Medicaid expansion and so forth. The major provisions of the ACA fall under the Department of Health & Human Services (HHS), and within that, the Centers for Medicare & Medicaid (CMS)
Every year, CMS issues a long, wonky document called the Notice of Benefit & Payment Parameters (NBPP) for the Affordable Care Act. This is basically a list of proposed tweaks to some of the specifics of how the ACA is actually implemented for the following year.
The graph purported to break out "Obamacare applications by state for 2025" by states which voted for Donald Trump vs. those which voted for Kamala Harris in November 2024. Here's what it looked like:
As I noted at the time, this graph was technically accurate...while simultaneously being jaw-droppingly misleading, for several reasons, including:
This morning, the Twitter account NewsWire_US, which claims to be a "U.S. and world news aggregator," posted an amazing-looking graph which purports to break out "Obamacare applications by state for 2025" by states which voted for Donald Trump vs. those which voted for Kamala Harris last month.
Here's the graph, which includes no further context (including any data sources...NewsWire claims it came from Reuters but I can't find the original link to a story by them with this graph) beyond making it look like a whopping 82% of ACA enrollees live in Trump states:
Update: Here's the original Reuters article, which was actually published on Dec. 11th, which at least explains why it only includes data through Nov. 16th/9th, anyway.
The Centers for Medicare & Medicaid Services (CMS) is committed to a robust Marketplace Open Enrollment process for consumers so they can easily purchase high-quality, affordable health care coverage. CMS reports that a record 16.6 million consumers signed up for plan year 2025 and will receive up to a full year of coverage beginning January 1. Of those consumers, 2 million are new to the Marketplace this year. This represents selections in the 31 states that use HealthCare.gov. Plan selection continues in most State-based Marketplaces, as well. The next national snapshot will be available in early January.
The footnote at the bottom confirms: "These metrics reflect available Federally-facilitated Marketplaces (FFMs) data through December 18, 2024."
The Centers for Medicare & Medicaid Services (CMS) has published two 2025 ACA Open Enrollment Period "snapshot reports," both of which had above-the-fold numbers which make it look as though enrollment numbers are lagging significantly behind last year's record-breaking totals:
