Billionaire investor Mark Cuban warned that artificial intelligence (AI) may worsen rather than improve the functioning of the United States healthcare system. He made the remarks in response to Marc Andreessen’s claim that AI already performs better than most human doctors.
The core of the debate
Cuban argues the central battle is not over diagnosis. Instead, he says the real issue is how insurers, pharmacy benefit managers (PBMs), and other intermediaries might deploy AI agents to protect their profit margins. Those agents could be used to delay, deny, or otherwise contest claims automatically.
Time and cost impacts
According to Cuban, intermediaries already consume a significant share of clinicians’ time—roughly 25% of a doctor’s time, by his estimate. He also noted that hospitals sometimes pay firms up to 10% of revenue to fight back on billing, reimbursements, and revenue-cycle disputes.
What AI could change
Proponents of AI point out that agents could reduce administrative burdens for clinicians by automating paperwork, prior authorizations, coding, and billing. Cuban cautions that if insurers and large conglomerates deploy countervailing agents, the result may not be waste removal but an automated, adversarial contest in which every dollar of care must survive machine-speed bureaucracy.
Takeaway
Cuban’s central point is that AI does not automatically fix broken incentives. In the US healthcare context, the technology could simply give those who profit from the existing maze faster tools to defend their margins and preserve administrative barriers.
