Mark Cuban has a bold offer for Elon Musk

 Many billionaires in the world have more than enough money to fix some of the problems that make life harder than it needs to be.

Take Jeff Bezos, for example, who Forbes reported as the second-richest person in the world in 2025 with a net worth of $203.6 billion. 

The former Amazon CEO has used a portion of his riches to address climate change and support a preschool network in low-income communities by creating the Bezos Earth Fund and Bezos Day One Fund, respectively. While many criticize the evils of the company he created in Amazon, it can't be denied that he's used some of his billions to foster good.

Elon Musk, the world's richest man, also established a philanthropic business with his Musk Foundation, which he set up in 2001. However, the foundation has come under public scrutiny over the years, having no full-time staff and allegedly having “failed in recent years to give away the bare minimum required by law." The New York Times called the Musk Foundation "haphazard and largely self-serving."

Another high-profile billionaire known for philanthropy and spending his money on meaningful causes is "Shark Tank" alumni Mark Cuban, whose Cost Plus Drugs business launched in 2022 with the aim of "eliminating the middleman" and offering medications at affordable prices. 

Cuban and Musk have famously gone back and forth on social media over a variety of topics, with Cuban making a point of asking Musk hard questions about his businesses than often go unanswered. 

Now, Cuban's issued an interesting challenge to Elon Musk via his X platform, and it would be quite notable if Musk followed through.

Cuban wants to work with Elon Musk

In a tweet posted on on X on May 1, a physician using the handle RealDocSpeaks posted a troubling chart from pharmacist Jeremy Counts.

Counts' original post reads, "Virginia Medicaid is paying more per member for medication than any state in the country, and nearly none of that money is getting to independent pharmacies. We MUST have the transparency a single PBM brings to rein in drug costs @GovernorVA."

The post included a list of medications and their markups in the state of Virginia. Calcitrol, which treats low calcium levels caused by kidney disease, topped the list with an astonishing markup price of 22,441% more than what Ohio pays for the same drug. 

RealDocSpeaks commented on the reshared post, saying, "There is plenty of money in health care, it is just going to the wrong people. Our current system rewards useless middlemen and punishes those caring for patients. In short, our system is backwards. It is time to reward pharmacists, physicians, physical therapists, and all who help patients daily. It is time to eliminate as many middlemen as possible."
