AncestryDNA vs 23andMe in 2026

The short verdict

For genealogy, AncestryDNA is the stronger choice. It has the bigger match pool and connects to Ancestry's family trees and records, which is where most people break through brick walls.

For health, 23andMe is the only one of the two with a health product. Its reports are limited to selected variants, though, so treat them as screening prompts rather than diagnoses.

We have not tested either kit. This comparison uses each company's own product, pricing and privacy pages, regulator actions and news reporting, all opened on October 30, 2026.

Prices and memberships

The kit price is only the start. Both companies sell recurring memberships, and those renew automatically.

23andMe requires a payment method at kit registration for Premium Ancestry + Health, and it renews at $99 a year. Its page says you can cancel anytime in Account Settings. It does not say whether premium reports stay visible after you cancel.

Ancestry results and matching

Database size

Relative matching is only as good as the pool you are matched against. Ancestry cited a DNA network of over 18 million people when Blackstone completed its $4.7 billion purchase of the company in December 2020.

More recent figures come from The DNA Geek, a genealogy blog. In March 2026 it reported AncestryDNA was close to 30 million kits, while 23andMe was just under 14 million. These numbers were gathered at a genealogy conference and are approximate.

Regions and extra features

Ancestry advertises 4,800+ regions and places, plus 93 African ethnic groups. 23andMe advertises 5,000+ regions worldwide. The two companies define regions differently, so the counts are not a like-for-like measure of precision.

• AncestryDNA kit: ethnicity estimate, DNA matches and origins report. DNA by Parent, Regions by Grandparent and 100+ traits need a membership.
• 23andMe Basic: geographic origins, a family tree and the basic DNA Relative Finder.
• 23andMe Premium Ancestry: adds the advanced relative finder, which connects you with up to 5,000 DNA relatives, plus historical matches and reconstructed ancestors.

The real differentiator for genealogists is records. Ancestry's memberships unlock U.S. and international records, newspapers and military records. 23andMe does not sell a records archive.

Health reports

Ancestry's DNA page listed no health product on October 30, 2026. Its paid add-ons are traits and records, not disease risk.

23andMe's Premium Ancestry + Health tier lists 50+ genetic health screenings and carrier reports. It also includes pharmacogenetic reports, a family health history tree and new reports added during the year.

The BRCA example

23andMe's BRCA report is a good illustration of the limits. Its product page says the report covers 44 variants in BRCA1 and BRCA2, does not represent most BRCA variants in most ethnicities and does not test other hereditary cancer genes.

A negative result therefore does not rule out a harmful variant. A positive one should be confirmed in a clinical lab before any medical decision. Our guide to bringing DNA results to your doctor walks through that conversation.

23andMe's page also notes that some of its health predisposition reports meet FDA requirements, while others are based on its own research and have not been FDA reviewed.

Ownership: what changed at 23andMe

23andMe filed for Chapter 11 bankruptcy on March 23, 2025. Regeneron won the first auction, but the court reopened bidding, and TTAM Research Institute won with a $305 million offer.

TTAM, a California nonprofit public benefit corporation founded and led by co-founder Anne Wojcicki, completed the purchase on July 14, 2025. It acquired the Personal Genome Service and the Research Services business. TTAM's announcement said customers could change their research participation decision.

According to a September 2025 consumer alert from the Minnesota Attorney General, TTAM renamed itself 23andMe Research Institute on July 17, 2025. State attorneys general also negotiated protections in the sale, including a consumer privacy ombudsman, a continued right to delete data and annual independent audits of data safeguards.

The website now lives at 23andme.org, and the old .com addresses redirect there. The privacy statement was last updated May 19, 2026.

Ancestry has had a single owner for longer. Blackstone's funds completed their acquisition in December 2020.

Privacy, breaches and deletion

The 2023 23andMe breach

In 2023, attackers used stolen passwords to get into 23andMe accounts and reached data on about 6.9 million users through relative-matching links. The UK Information Commissioner's Office fined 23andMe £2.31 million in June 2025, citing the lack of multi-factor authentication.

On May 28, 2026, California's Attorney General sued Chrome Holding Co., formerly known as 23andMe, over the same breach. The suit targets the former company, not the new nonprofit owner.

Policy comparison

23andMe's privacy statement also says it will not sell or transfer genetic data in a future sale or bankruptcy unless the buyer meets set conditions. For a full walkthrough of the new 23andMe's settings, read 23andMe in 2026: is it safe?

How to choose

1. Name your main goal. Finding relatives and building a tree points to AncestryDNA. Health screening points to 23andMe.
2. Price the full first year. Add shipping, memberships and renewals. A $99 kit with an All Access bundle becomes far more expensive if left running.
3. Turn on two-factor login. The 2023 breach worked because passwords alone were enough. Use a unique password too.
4. Decide on research consent before you activate. Both companies make research optional, and you can change your choice later.
5. Plan for a health surprise. Know in advance who you would call. A genetic counselor can explain what a selected-variant result does and does not mean.
