Billionaire investor Mark Cuban is making it clear he’s not interested in a political reunion with Kamala Harris. Speaking at POLITICO’s Health Care Summit, Cuban dismissed the idea of supporting Harris in a potential 2028 presidential run, despite having backed her campaign just a few years ago.
Asked directly whether he would support Harris if she entered the race again, Cuban’s response was blunt: “No.” Pressed further about her 2024 campaign messaging, particularly on health care, he added, “Don’t remember, don’t care… Those days are gone.”
Harris, for her part, has recently signaled openness to another White House bid. During an appearance at the National Action Network Convention, she told Rev. Al Sharpton that she is “thinking about” running again in 2028, offering her most direct acknowledgment yet of a possible comeback.
Cuban, however, emphasized that his focus has shifted away from electoral politics and toward reforming the U.S. health care system. “I’m trying to change how messed up this health care industry is right now, and that’s all I care about,” he said. Notably, he indicated a willingness to support candidates from either party who align with his reform goals, even praising efforts by President Donald Trump to lower drug prices and accelerate clinical trials.
His criticism extended to lawmakers as well. Cuban expressed frustration with the lack of momentum behind bipartisan legislation led by Sens. Josh Hawley and Elizabeth Warren aimed at curbing health care consolidation. He argued that without breaking up large insurance and health care conglomerates, consumers would remain at their mercy.
The issue is gaining traction in Washington. Rep. Jason Smith recently criticized “health insurance empires” during a congressional hearing, while Health Secretary Robert F. Kennedy Jr. called for stronger antitrust enforcement.
Cuban, who co-founded Cost Plus Drugs, also took aim at pharmacy benefit managers, arguing their pricing power can devastate pharmaceutical companies. A spokesperson for the industry pushed back, calling Cuban’s claims misleading.
While Cuban floated the idea of an independent presidential candidate focused on health care affordability, he ruled himself out. “It won’t be me,” he said.
