In May 2010, H. Ross Perot Jr., who retained 5% ownership, filed a lawsuit against Cuban, alleging the franchise was insolvent or in imminent danger of insolvency.

Cuban has repeatedly expressed interest in owning a Major League Baseball franchise and has unsuccessfully attempted to purchase at least three franchises. In 2008, he submitted an initial bid of $1.3 billion to buy the Chicago Cubs and was invited to participate in a second round of bidding along with several other potential ownership groups.{{cite web |url=https://www.espn.com/mlb/news/story?id=3503599 |title=Report: Cubs cut number of bids to at least three, including Cuban |publisher=ESPN |date=July 24, 2008 |access-date=November 30, 2021 |archive-date=November 30, 2021 |archive-url=https://web.archive.org/web/20211130054128/https://www.espn.com/mlb/news/story?id=3503599 |url-status=live }} Cuban was not selected to participate in the final bidding process in January 2009. In August 2010, Cuban actively bid to buy the Texas Rangers with Jeffrey L. Beck. Cuban stopped bids after 1 a.m., having placed bids totaling almost $600 million. He had outbid a competing ownership group led by ex-pitcher and Rangers executive Nolan Ryan, but lost the deal before the Rangers played the San Francisco Giants in the 2010 World Series.

In January 2012, Cuban placed an initial bid for the Los Angeles Dodgers, but was eliminated before the second round of bidding. Cuban felt that the value of the Dodgers' TV rights deal drove the price of the franchise too high.{{cite web|url=http://www.cbssports.com/mcc/blogs/entry/22297882/34631046 |title=Cuban explains losing out on Dodgers |publisher=CBSSports.com |access-date=June 29, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120313025519/http://www.cbssports.com/mcc/blogs/entry/22297882/34631046 |archive-date=March 13, 2012 }} He had previously said that he would not be interested in buying the franchise at $1 billion,{{cite web |url=http://aol.sportingnews.com/mlb/feed/2011-04/dodgers-ownership/story/mark-cuban-wont-pay-1-billion-for-dodgers |title=Mark Cuban won't pay $1 billion for Dodgers |publisher= Sporting News |date=November 1, 2011 |access-date=June 29, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120507010626/http://aol.sportingnews.com/mlb/feed/2011-04/dodgers-ownership/story/mark-cuban-wont-pay-1-billion-for-dodgers |archive-date=May 7, 2012 |df=mdy-all }} telling the Los Angeles Times in November 2011 "I don't think the Dodgers franchise is worth twice what the Rangers are worth."{{cite web|url=https://www.latimes.com/sports/la-xpm-2011-nov-02-la-sp-1102-dodgers-mark-cuban-20111102-story.html|title=Cuban offered to buy Dodgers but price was too high|work=Los Angeles Times|first=Bill|last=Shaikin|date=November 2, 2011|access-date=November 29, 2021|archive-date=November 27, 2021|archive-url=https://web.archive.org/web/20211127235332/https://www.latimes.com/sports/la-xpm-2011-nov-02-la-sp-1102-dodgers-mark-cuban-20111102-story.html|url-status=live}} However, as the bidding process drew near many speculated that the sale would surpass $1.5 billion, with Jon Heyman of CBS Sports reporting on Twitter that at least one bid in the $1–1.5 billion range was placed in the initial round of the bidding process.

Cuban's advice to Reddit users was to hold GameStop shares if they could afford it in anticipation of additional short sales by Wall Street firms, but ultimately acknowledged that the odds were stacked against them and to use it as a learning experience.

In a September 2016 interview with NPR, Cuban effectively positioned himself to support Clinton.

In a June 2020 interview with CNN and former Obama advisor David Axelrod, Cuban revealed that he had seriously considered running for president that year as an independent candidate. He went so far as to commission a national poll, which, according to Cuban, showed he would only receive 25 percent of the vote in a hypothetical matchup with President Donald Trump and former Vice President Joe Biden. Cuban also said that the poll showed his candidacy would have pulled votes from both Trump and Biden.{{cite web|url=https://www.businessinsider.com/mark-cuban-commissioned-presidential-poll-biden-trump-2020-6|title=Mark Cuban commissioned a 3-way poll last month as he considered running as an independent against Biden and Trump in the 2020 presidential election|first=Jake|last=Lahut|website=Business Insider|access-date=June 5, 2020|archive-date=June 5, 2020|archive-url=https://web.archive.org/web/20200605161527/https://www.businessinsider.com/mark-cuban-commissioned-presidential-poll-biden-trump-2020-6|url-status=live}}
