Mark Cuban appeared at a White House event with President Donald Trump on May 18 to announce a major expansion of the TrumpRx platform, now listing over 600 generic drugs aimed at reducing medication costs for consumers [1, 2].

The expanded platform partners with Cost Plus Drugs, which Cuban co-founded, as well as Amazon Pharmacy and GoodRx to drive down drug prices [1, 2]. Cuban described the effort as bipartisan, saying, "Democrats want cheaper medications, too. When all is said and done, the goal is the goal. How do we make medications and healthcare cheaper? That's all I care about" [2]. He also said, "Tell me one person who thinks that healthcare economics are well run in this country. It’s the biggest affordability issue" [1].

Trump used the event to defend a controversial $1.8 billion fund related to January 6 rioters and took questions on the Iran war [1]. On stage, Trump joked about Cuban's past support for Kamala Harris in the 2024 election, saying, "Well, he made a mistake. It was a big mistake" [1, 2]. Cuban declined to discuss regrets about his 2024 endorsement, stating, "I’m not going into my politics at all" [1, 2].

Cuban also acknowledged regret over selling majority ownership of the Dallas Mavericks to the Adelson family, known major Trump donors [2]. After the event, Cuban posted a now-deleted social media message defending his White House appearance with profanity towards critics [1].

The White House event highlighted the partnership’s focus on lowering healthcare costs without political divisions [2]. The expanded TrumpRx platform launch took place May 18 and aims to increase consumer access to affordable generic drugs through collaboration with multiple pharmacy and drug discount services [1, 2].
