Billionaire investor Mark Cuban on Sunday renewed calls to break up large healthcare conglomerates, arguing that vertically integrated insurers and providers have gained too much control over the U.S. healthcare system.

Posting on X, Cuban said major healthcare carriers and providers were “abusing their market positions” while regulators, including the Federal Trade Commission, failed to stop consolidation over the past decade.

“There is a reason we have anti-trust laws,” Cuban wrote. “If you want less government in healthcare, it can’t happen until these conglomerates are broken up.”

Cuban also criticized lawmakers for failing to support the bipartisan “Break Up Big Medicine” bill introduced by Sen. Josh Hawley (R-MO) and Sens. Elizabeth Warren (D-MA) 

He claimed several Democratic senators privately supported the legislation but were reluctant to publicly endorse it unless more Republicans joined the effort.

“Other than Josh, not a single Republican senator I have talked to has the guts to stand up for it,” Cuban wrote.

Cuban Targets ‘Big Medicine’

Cuban has repeatedly criticized consolidation across the healthcare industry, particularly the growing influence of vertically integrated insurers and pharmacy benefit managers.

Earlier this year, Cuban said large insurance companies controlled too many layers of healthcare, including pharmacy benefit managers, wellness programs and drug access.

“There’s just no way to compete with these enormous companies that just don’t care,” Cuban said during a policy conference in Washington earlier this year. “You have to break them up.”

Cuban also argued that financial pressures on doctors were accelerating consolidation. In a separate X post this month, he said rising medical school debt was pushing physicians to sell independent practices and join large healthcare systems.

Drug Pricing Remains Key Focus

The billionaire entrepreneur has increasingly positioned healthcare affordability and pricing transparency as central policy concerns.

Earlier this month, Cuban appeared alongside President Donald Trump during the expansion of the TrumpRx prescription drug platform, which added more than 600 generic medications.

At the event, Cuban praised efforts to reduce prescription drug costs, saying “anything that saves patients money is a win.”
