| UnitedHealth CEO’s private healthcare investments raise conflict concerns |
UnitedHealth Group chief executive Stephen Hemsley has quietly made tens of millions of dollars in private investments in healthcare startups through his investment firm, Cloverfields Capital, including companies that do business with - or compete against - UnitedHealth, according to a Wall Street Journal investigation. The investments, some dating back at least seven years, were not publicly disclosed by UnitedHealth or the startups involved. Ethics experts say the arrangements create potential conflicts of interest, given UnitedHealth’s vast footprint across insurance, healthcare services and technology. Hemsley, who returned as CEO in May 2025 after previously serving as chief executive and chairman, founded Cloverfields in 2019. While the firm publicly reports investments in listed companies, it has also taken stakes in private healthcare ventures, including digital health providers and firms connected to UnitedHealth’s business ecosystem. In some cases, internal documents suggest efforts were made to keep Hemsley’s involvement out of written communications. UnitedHealth said Hemsley complies with all conflict-of-interest and disclosure policies. After resuming the CEO role, he transferred his healthcare-related investments into an independently managed trust and recused himself from related corporate decisions. However, the company has not publicly detailed the trust or the investments.
