The Trump Regime has published an update to the official Medicaid/CHIP enrollment data:

June 2025 Key Findings

Medicaid and CHIP Enrollment

• In June 2025, 77.7 million individuals were enrolled in Medicaid and CHIP.
• 70.5 million individuals were enrolled in Medicaid, and 7.2 million individuals were enrolled in CHIP.
• 40.7 million adults were enrolled in Medicaid, and there were 37.0 million Medicaid child and CHIP enrollees.

Back in March I wrote about a proposed rule (really a set of rules) put out by the Trump Regime's Centers for Medicare & Medicaid Services (CMS) which, if implemented, would make major changes to how the Affordable Care Act is administered. This rule was finalized in June, with some provisions kicking in immediately, most starting January 1st and others over the next couple of eyars.

This set of regulatory changes is completely separate from the impending expiration of the improved premium tax credits which I've written so much about; these have to do with the specifics of how the ACA is actually implemented going forward.

A very simple example of this is the length of the annual Open Enrollment Period, which has ranged from as long as 6 months during the very first OEP in 2013-2014 to as short as just 75 days during most of the first Trump Administration.

April 2025 Key Findings - Medicaid and CHIP Enrollment

• In May 2025, 78.1 million individuals were enrolled in Medicaid and CHIP.
• 70.8 million individuals were enrolled in Medicaid, and 7.3 million individuals were enrolled in CHIP.
• 40.9 million adults were enrolled in Medicaid, and there were 37.2 million Medicaid child and CHIP enrollees.

The Centers for Medicare & Medicaid Services (CMS) has posted an official update to the enrollment data for ACA Medicaid expansion through December 2024.

According to the new report, total enrollment from September through December actually increased by just a hair (5,377) and still remained at over 20.7 million nationally, so it doesn't look like the Trump Admin has started cooking these particular books, at least not yet.

I've been able to cobble together more recent ACA expansion enrollment for about half of the 40 states (+DC) which participate in the program:

via the Washington Health Benefit Exchange:

Public comment at Washington Health Benefit Exchange Board  includes 10 testimonials, plus additional stories 

OLYMPIA, Wash. – Washingtonians shared stories of how access to more affordable health insurance has affected lives and communities all across the state, with Washington Health Benefit Exchange (Exchange) Board last week. The testimonials were particularly impactful in light of a myriad of recent federal changes to state-based marketplaces such as the Exchange, and the impending potential expiration of enhanced premium tax credits (ePTC) before Congress.

Now that I've finally completed overhauling & updating my House District Healthcare Enrollment Pie Chart project with the latest data, I wanted to address a rather frustrating elephant in the room.

For most of the healthcare programs involved, the enrollment data is now reasonably up to date:

• ACA Qualified Health Plan (QHP) enrollment is as of February 2025 via official Centers for Medicare & Medicaid Services (CMS) public use files.

• ACA Basic Health Plan (BHP) enrollment is as of April 2025 (NY), May 2025 (OR) or July 2025 (MN) via each state's health department monthly reports.

via the Washington Health Benefit Exchange:

OLYMPIA, Wash. – Ingrid Ulrey, CEO of Washington Health Benefit Exchange, the state-based marketplace for Affordable Care Act plans, released a statement today following the Centers for Medicare and Medicaid (CMS) announcement of the 2025 Marketplace Integrity and Affordability Final Rule.  

“Together, this major new regulatory action, plus imminent Congressional action on the One Big Beautiful Bill Act, plus the potential expiration of enhanced premium tax credits at the end of this year is a perfect storm for nearly 300,000 Washingtonians who rely on our marketplace to purchase private health insurance.” 

A few weeks ago, the Congressional Budget Office (CBO) issued their official projection of just how much damage the combined effect of the House GOP's budget reconciliation bill (officially the "One Big Beautiful Bill Act") would cause to healthcare coverage in the U.S.: Over 16 million Americans would lose coverage, over half of whom (~8.2 million) are currently enrolled in ACA exchange plans.

If this happens, it would mean the ACA exchange market would drop by more than 1/3 from the ~24.2 million currently enrolled (myself & my own family included).

However, I've repeatedly stated that even this is likely a low estimate--the remaining ~16 million exchange enrollees would still be hit with MASSIVE (and in some cases eye-poppingly huge) premium hikes which would force them to drop to far worse plans (meaning much higher deductibles & co-pays; worse provider networks and so on).
