Regeneron Buys 23andMe: What Happens to Your DNA Data?

What happens to your 23andMe DNA data after the company's bankruptcy sale? If you're one of the over 15 million users who submitted a genetic sample through 23andMe's popular DNA testing kits, you're likely wondering what Regeneron Pharmaceuticals’ $256 million acquisition means for your personal data. As the bankrupt genetic testing firm hands over “substantially all” of its assets—including its massive genetic biobank and research division—the privacy, ownership, and future use of consumer DNA data are becoming pressing concerns.

23andMe, once valued at $6 billion after going public in 2021, filed for bankruptcy in March 2025. The company struggled to remain profitable despite its dominant position in the consumer genetics market. Now, Regeneron Pharmaceuticals, a major player in the biotech and pharmaceutical industries, has emerged as the winning bidder in a bankruptcy auction, acquiring the company's assets in a move expected to close later this year, pending US Bankruptcy Court approval.

This acquisition isn't just about saving a bankrupt business. It's a strategic investment by Regeneron aimed at accelerating large-scale genetic research and drug development. By obtaining access to 23andMe’s Total Health and Research Services and anonymized genetic data, Regeneron is positioning itself to lead the next frontier of precision medicine and pharmaceutical innovation.

Privacy advocates, however, are raising concerns. While 23andMe has stated that customer data is anonymized and that physical genetic samples are destroyed upon account deletion, the lack of full transparency leaves users questioning just how much of their personal information may now be accessible to a pharmaceutical giant.  

Anne Wojcicki, 23andMe’s co-founder and former CEO, stepped down as the company filed for bankruptcy, marking the end of an era for one of Silicon Valley’s most well-known health tech startups. Despite its fall from grace, 23andMe’s brand and mission will live on under Regeneron’s umbrella. According to 23andMe chair Mark Jensen, the acquisition allows the company’s mission of “helping people access, understand, and gain health benefits through their genome” to continue—while also offering job security for employees involved in the acquired business units.

This acquisition also marks a significant shift in how consumer genetic data may be used moving forward. Regeneron's co-founder, George D. Yancopoulos, expressed excitement about the potential of integrating 23andMe’s data into new therapeutic pipelines. With data-driven healthcare innovation on the rise, this merger opens the door to drug discovery fueled by vast genomic datasets—one of the most valuable commodities in modern biotech.

For consumers, though, the question remains: what level of control do you still have over your DNA once it's been analyzed? Even if the data is anonymized, advances in AI and data reidentification techniques could potentially expose individuals, making healthcare data security a hot-button issue.

This deal comes at a time when interest in personalized medicine, biotech investments, and DNA data monetization is skyrocketing. Investors are eyeing the long-term value of genetic information, and pharmaceutical companies are racing to integrate this data into their R&D efforts.  

As more consumers opt into at-home DNA testing, often in exchange for health insights or ancestry reports, the fine print surrounding data use becomes increasingly important. The 23andMe-Regeneron deal underscores the evolving landscape of digital health, where the line between personal data ownership and corporate research utility grows ever blurrier.

If you're a current or former 23andMe user, it may be wise to review the company’s data retention policies, request sample destruction if you're concerned, and monitor developments closely as Regeneron finalizes its takeover. Understanding how your DNA data is used—and potentially monetized—will be crucial in this new era of biotech consolidation.
