Sen. Markwayne Mullin purchased as much as $100,000 worth of UnitedHealth Group stock in late February, adding to his portfolio during a turbulent stretch for the nation’s largest health insurer.
The Oklahoma Republican disclosed a buy of UNH valued between $50,000 and $100,000 on Feb. 25, 2026, according to a periodic transaction report filed with the Senate. Based on the reported range, the investment is estimated at roughly $75,000.
- Date: Feb. 25, 2026
- Type: Buy
- Amount: $50,000–$100,000

UnitedHealth shares closed Friday at $282.09, giving the company a market capitalization of about $256 billion. The stock has swung sharply over the past year, trading between $234.60 and $606.36 in its 52-week range. That volatility follows mounting regulatory scrutiny, shifting Medicare Advantage reimbursement policies, and broader pressure on managed care margins.
Mullin’s purchase came as the stock hovered closer to the lower end of that annual range than its highs, potentially signaling a bet on stabilization or recovery in the health insurance giant.
Health Policy Oversight
The trade is notable given Mullin’s committee assignments. He serves on the Senate Committee on Health, Education, Labor, and Pensions (HELP), including its Employment and Workplace Safety and Primary Health and Retirement Security subcommittees. The HELP panel has jurisdiction over major health policy matters, including public health agencies and aspects of private insurance regulation.
UnitedHealth, as the largest U.S. health insurer and a major Medicare Advantage provider, is frequently affected by congressional decisions on reimbursement rates, healthcare transparency, and benefit design.
Mullin also sits on the Senate Committee on Appropriations and the Senate Committee on Armed Services, broadening his influence across federal spending and defense policy. While those panels do not directly oversee private insurers, appropriations decisions can shape healthcare funding levels and regulatory agency resources.
A Widely Held Congressional Stock
Mullin is far from alone on Capitol Hill in trading UnitedHealth. At least 90 lawmakers have reported transactions in the company, making it one of the most commonly traded healthcare stocks among members of Congress.
Since entering Congress, Mullin has disclosed 468 trades, reflecting an active approach to portfolio management compared with many of his peers. His latest UnitedHealth purchase adds to a record that spans multiple sectors and market cycles.
Lawmakers are required under the STOCK Act to disclose stock transactions within 45 days, a rule intended to provide public transparency into their investment activity.
UnitedHealth remains a bellwether for the broader managed care industry. Investors are closely watching how insurers navigate Medicare Advantage payment adjustments and medical cost trends in 2026. With shares still well below their 52-week high, the stock’s trajectory will likely hinge on regulatory clarity and earnings performance in the quarters ahead.
For readers tracking activity across Capitol Hill, Mullin’s purchase is one of the latest congressional trades involving a healthcare heavyweight whose fortunes are closely tied to federal policy decisions.
