The world of social media recently took an expected turn, and some members of the tech community are applauding it, including Mark Cuban.
Since he left his position as a judge on “Shark Tank” in 2018, Cuban has mostly kept busy with his public benefit pharmaceutical company, Cost Plus Drugs. But he often chimes in on major tech developments, often involving artificial intelligence (AI) and social media.

Over the past year, a new platform has risen to prominence, threatening the dominance held by Facebook and X. Bluesky has garnered popularity among the many users — now including Cuban —who have expressed disdain for the platforms owned by Elon Musk and Zuckerberg.
The outspoken tech billionaire has repeatedly praised the platform, on which he frequently shares quite a bit of content. In a recent post, he reiterated his support for Bluesky, celebrating one of its recent achievements.

Mark Cuban has let the world know which social media platform he prefers
When Cuban first joined Bluesky in November 2024, he announced his presence on the platform with a four-word post that has since become iconic in the anti-X community: “Hello Less Hateful World.”
While he didn’t offer any further commentary on that particular post, it is believed that Cuban considered Bluesky to be the less-hateful alternative to X, a platform that previously received the bulk of his content. While he still posts to the network, he has scaled back his activity on it since joining Bluesky.

Cuban isn’t the only person who has taken solace on Bluesky since November 2024. Following President Donald Trump’s victory, many people fled X for Bluesky, often citing an abundance of hateful and misleading content as their primary catalyst for switching.
Now, Bluesky is still growing and broadening its appeal to certain communities who previously utilized X for sharing their work. Researchers have found that the platform has cultivated a community of sharing academic research that has overtaken X in terms of traction.
“Analysis by experts at Digital Science found that while X still has a much larger volume of research posts overall, Bluesky hosted more posts linked to work published in 2025 for the first time in March,” reports the UK’s Times Higher Education.
While the outlet reported on these findings in April 2024, Cuban shared the article on his Bluesky profile on May 4 with the caption “Love to see it !!!,” making it clear he applauds the platform’s success.
This trend began to take shape around the same time Cuban joined Bluesky.Â
Prominent academics began to announce they would be leaving X in the wake of Trump’s victory. Jay Rosen, as associate professor of journalism at New York University, announced his exit on November 8, 2024, stating that the platform is no longer a way to “do journalism education in public, for a public — and for free.”

As Inside Higher Education reports, other high-profile academics who have left X include Paul LeBlanc, former president of Southern New Hampshire University, and associate professor Isaac Kamola of Trinity College, CT. All three remain active on Bluesky.
Cuban isn’t backing down on his pro-Bluesky crusade
Throughout the rise of Bluesky, Cuban has made it clear that he believes the world needs alternatives to the prominent social media platforms. In January 2025, he shared a formula for users to help the platform grow at the expense of X and Musk.

“Is it worth 20 MINS a day to proactively recruit and bring your friends, neighbors, relatives, businesses, anyone who is or could be a user, to @bsky.app?” he asked. “If Bluesky ends up with more users than the others, you destabilize Musk, Zuck, Trump.”
In the months that followed, Cuban would back a startup called Skylight, an alternative to TikTok built on the same decentralized social networking protocol on which Bluesky operates, exactly the type of project he had said he wanted to get behind.
As TheStreet’s Colette Bennett reports, “That comes with a few huge bonuses, the biggest of which is that those new to the platform can instantly tap into BlueSky’s 33.8 million users (for instance, BlueSky users can see and comment on Skylight posts).”
Now, Cuban has a new cause to celebrate, as Blueksky continues to demonstrate progress and provide a valuable platform for those who have taken a stand against Musk. Its success at luring the Academic Twitter to its side suggests that the decentralized social network has plenty of room to run.Â
