Short answer: Yes. Mark Cuban, who is Jewish, has said directly and on the record that he is "pro-Israel to the core, because I'm Jewish." He has also called himself "anti-Hamas to the core," spoken out against antisemitism, and offered public support to Jewish college students after October 7, 2023. He sold his majority stake in the Dallas Mavericks in November 2023 and is now a minority owner; basketball operations passed out of his control in 2024.
What Mark Cuban has actually said and done
- October-November 2022: When then-Nets guard Kyrie Irving promoted an antisemitic film and initially refused to apologize, Cuban weighed in publicly, saying Irving was "not educated about the impact" of his platform. Cuban added he didn't think Irving had "a bad heart," but that Irving had "a lot to learn," according to the Jewish Telegraphic Agency.
- February 5, 2023: In a twist Jewish outlets flagged at the time, Kyrie Irving was traded to the Dallas Mavericks, then majority-owned by Cuban, the same owner who had publicly criticized his antisemitism controversy months earlier, per JTA.
- November 2-3, 2023: Weeks after the Hamas attack on Israel, Cuban recorded a video message, shared through Hillel International, for Jewish college students facing a surge of campus antisemitism. He told them to "be proud of their Jewish heritage and stay strong," recalling being bullied as a Jewish child himself: "There's always going to be people who hate us... But our lives and who we are is not defined by who hates us. It's defined by who loves us and who we love." Reported by Algemeiner.
- November 28, 2023: Cuban announced he was selling his majority stake in the Dallas Mavericks to Miriam Adelson, a major pro-Israel Jewish philanthropist whose family foundation ranks among the top donors to Birthright Israel. JTA's coverage also noted Cuban's own family history: his paternal grandparents shortened their surname from Chabenisky after fleeing antisemitism in Russia. Full story at JTA.
- October 3, 2024: On the "All-In" podcast, Cuban stated it plainly: "I'm pro-Israel to the core, because I'm Jewish. I'm anti-Hamas to the core, they are terrorists. I want to see Israel succeed. I want to see the United States support them and help them in that." He also offered nuance, calling Israel's approach in Gaza "too blunt an instrument" while describing the response against Hezbollah as "the exact right way."

Who is Mark Cuban, and why his Jewish identity matters here
Mark Cuban is a billionaire entrepreneur, longtime co-star of Shark Tank, and former majority owner, now a minority owner, of the Dallas Mavericks. He sold his majority stake to Miriam Adelson in November 2023 but stayed on to run the team's basketball side. Cuban is Jewish: his paternal grandparents emigrated from Russia, shortening the family name from Chabenisky, and he has spoken openly about experiencing antisemitism as a child growing up in Pittsburgh.
His public involvement with Jewish and Israel-related issues stretches back years, from criticizing Kyrie Irving's 2022 antisemitism scandal (while Irving still played for a division rival) to later becoming Irving's own team owner via trade, to recording a solidarity message for Jewish students after October 7, 2023. In October 2024, he stated on a major podcast that he is "pro-Israel to the core" because he is Jewish, while also voicing tactical criticism of Israel's Gaza campaign alongside that support. No record of Israel-specific financial donations, in-person Israel event appearances, or boycott refusals turned up in the public record through August 2026; his advocacy has mainly taken the form of public statements rather than financial commitments.
The bottom line
Mark Cuban supports Israel. He is Jewish, has said directly and on the record that he is "pro-Israel to the core," calls himself "anti-Hamas to the core," pushed back on antisemitism during the Kyrie Irving controversy, and offered public solidarity to Jewish college students after October 7, 2023, all while also voicing some tactical criticism of Israel's approach in Gaza alongside that support.
