Billionaire entrepreneur Mark Cuban praised the bipartisan Break Up Big Medicine Act in a social media post, urging President Trump to support the measure. He described the proposal by Senators Josh Hawley and Elizabeth Warren as a “no brainer” for lowering healthcare costs by dismantling vertical integration among insurers, PBMs and providers.

Modeled after the Glass-Steagall framework, the bill would prohibit common ownership of insurance, pharmacy benefit management and healthcare delivery entities. Integrated giants would be required to divest any conflicting subsidiaries within one year to eliminate self-dealing that inflates medical loss ratios and consumer premiums.

Under the act, UnitedHealth Group would need to separate its insurance operations from its pharmacy benefit manager and provider networks. This divestiture could disrupt revenue streams tied to integrated service offerings and alter cost synergies currently achieved through its vertically aligned structure.

The Federal Trade Commission and Department of Justice would oversee compliance, mandating divestiture within 12 months of enactment. Non-compliant companies could face profit disgorgement penalties, heightening regulatory risk for healthcare conglomerates entrenched in multi-segment operations.
