ACA Open Enrollment Begins Nov. 1 With Higher Premiums and Fewer Plan Options

ACA marketplace enrollment opened November 1 for 2027 coverage, and shoppers face higher premiums and a shrinking pool of insurers.

The Affordable Care Act's health insurance marketplaces opened for enrollment on November 1, kicking off the window for Americans to select or change their 2027 coverage through HealthCare.gov or their state's equivalent platform. This year's enrollment season comes with a notable warning for consumers: premiums are expected to be higher than last year, and the number of available plans has declined in many markets, meaning some shoppers may find their current insurer has dropped out of their area entirely. Both ABC News and NPR flag that getting an early start on enrollment is particularly important this year, precisely because the landscape of available options has shifted. Shoppers who wait may have less time to research alternatives or navigate unexpected gaps in coverage from insurers who have exited their region. The ACA marketplaces — established under the 2010 health law — allow individuals and families who don't get insurance through an employer or a government program like Medicaid or Medicare to purchase coverage, often with federal subsidies based on income. Tens of millions of Americans rely on these marketplaces for their health insurance.

Why it matters

Millions of Americans who purchase their own health insurance depend on ACA marketplaces, and rising premiums combined with fewer plan choices could leave some enrollees paying more for less competitive coverage. The changes make the enrollment window — which has a fixed deadline — especially consequential for shoppers who need to review their options rather than auto-renewing.

What's next

Shoppers have until the enrollment deadline (typically mid-December for January 1 coverage) to select a plan at HealthCare.gov or their state marketplace.

Key facts

• ACA marketplace open enrollment for 2027 coverage began November 1
• Premiums are expected to be higher in 2027 compared to the prior year
• The number of available insurance plans has decreased in many markets
• Coverage can be browsed and purchased at HealthCare.gov or state-run marketplace sites
• Both sources emphasize starting early as especially important this enrollment season

Bias & framing notes

Both sources are reputable outlets and agree on the core facts — enrollment start date, rising premiums, and fewer options. Neither source provided detailed numerical figures on premium increases or the count of insurer exits, making key claims somewhat general. NPR placed stronger emphasis on the urgency of enrolling early, while ABC framed the story more around what consumers should expect. No source provided a stated rationale from insurers or officials explaining why premiums are rising or why carriers are exiting markets.
