Mark Cuban Says 90 Drug Prices Dropped After Cost Plus Drugs Joined TrumpRx - Could Yours Be Next?

Prescription drug prices may already be dropping for some Americans, and more cuts could be on the way.

Mark Cuban says his company has already lowered prices on 90 medications since joining the Trump administration's drug pricing platform, raising the possibility that more savings could follow and making this a good time to check up on your financial health and see whether your prescriptions cost less elsewhere.

Prices are already coming down

In a recent post on X, Cuban said Cost Plus Drugs has reduced prices on 90 products since being listed on TrumpRx on May 18.

"Since Cost Plus Drugs was listed on TrumpRx on May 18, we have implemented price reductions on 90 products as part of our regular weekly pricing review process," he wrote. "We expect these price cuts will continue as our volumes grow."

That suggests the platform could become more competitive over time, especially if more consumers begin using it to compare prices and fill prescriptions.

What TrumpRx is trying to do

TrumpRx is designed to help consumers find lower-cost medications by comparing pricing options from manufacturers and online pharmacies.

The platform does not process insurance claims. Instead, it focuses on cash prices, which can sometimes be lower than insurance copays, especially for generic drugs.

By adding partners like Cost Plus Drugs, the program is aiming to increase price transparency and give consumers more options when filling prescriptions.

Prescription drug costs

Prescription drug costs remain a major expense for many Americans, which is why even small price reductions can make a difference. Nearly 3 in 10 adults report not taking their medications as prescribed at some point due to cost.

Spending on prescription drugs in the U.S. has also continued to rise and is expected to exceed $560 billion in 2026, a more than 8% increase from last year. Even for those with insurance, out-of-pocket costs can vary widely depending on the medication and pharmacy.

Generic drugs tend to be more affordable, but prices are not always consistent. The same medication can cost significantly different amounts depending on where it is purchased, which is part of what platforms like Cost Plus Drugs and TrumpRx are trying to address.

Cuban's White House moment

Cuban recently appeared at the White House alongside Donald Trump to highlight the expansion of TrumpRx.

During the event, the former "Shark Tank" star emphasized that lowering drug costs is one of the few issues with broad agreement across political lines.

"Republicans want cheaper drugs. Independents want cheaper drugs. Democrats want cheaper drugs," Cuban said. "I think we're going to do something special."

His presence was notable given his past political positions and underscored the growing focus on drug pricing as a pocketbook issue for Americans.

Why lower prices could continue

Cuban's pricing model is based on transparency and volume. As more people use Cost Plus Drugs, the company can negotiate better pricing and spread costs across a larger customer base, which can lead to ongoing price reductions, especially for widely used generic medications.

If TrumpRx successfully drives more traffic to these platforms, it could accelerate that trend.

Insurance is designed to lower healthcare costs, but it does not always guarantee the lowest price for prescriptions. In some cases, cash prices for generic medications can be cheaper than insurance copays, particularly when pharmacy benefit managers are involved in setting prices.

Cost Plus Drugs has built its model around transparent pricing, adding a fixed markup to wholesale drug costs rather than negotiating through traditional insurance channels. As more consumers compare pricing across platforms, those differences are becoming more noticeable, which could influence how people choose to fill their prescriptions.

How this could affect your prescriptions

For consumers, the biggest takeaway is simple: it may be worth actively comparing prices before filling a prescription. In some cases, paying cash through a platform like Cost Plus Drugs or using TrumpRx listings could be cheaper than going through insurance.

That is particularly true for common generics where pricing can vary widely between pharmacies. However, the savings will depend on the specific medication, dosage, and location, which makes it worth checking whether any recurring prescriptions could be filled more cheaply through these platforms.

Savings won't apply to every drug

Not every prescription will see the same level of savings. Brand-name drugs, specialty medications, and treatments that rely heavily on insurance coverage may not benefit as much from cash-price platforms.

While some consumers could see meaningful reductions, others may notice little difference depending on what they are prescribed.

What to watch next

The early price cuts are a promising sign, but it's still unclear how broadly the savings will spread.

Much will depend on whether more drugs are added, more pharmacies participate, and whether consumers actually change how they fill prescriptions.

There are also limits to the model. Brand-name drugs and medications covered heavily by insurance may not see the same level of savings.

Bottom line

Falling prices on platforms like Cost Plus Drugs and TrumpRx highlight how much prescription costs can vary, especially for common medications, and Cuban says more cuts could be on the way as usage grows.

Taking a few minutes to compare prices before filling a prescription may help you keep more cash in your wallet as more alternatives to traditional insurance pricing become available.
