Mark Cuban is diving headfirst into the AI video boom — and he says it's just for "fun."
The billionaire investor and former "Shark Tank" star said on Thursday that his "Cameos are open" on OpenAI's video-generation platform, Sora — appearing to be one of the first major public figures to openly experiment with the tool.
In posts on both X and Bluesky, Cuban told followers: "For those of you on Sora, my Cameos are open. Have at it."
In a separate X post, he added that users can join the platform with a personal invite code, writing: "My Sora cameos are going so well they gave me a code to share. Download Sora 2 and use MCUBAN as your invite code! Have fun!"
The posts, viewed more than 800,000 times combined as of early Friday morning, suggest Cuban is actively promoting it to his social-media followers.
Cuban told Business Insider it was "just me having fun," confirming that "anyone can use my likeness to make a cameo."

Sora 2 has quickly become a cultural flash point.
As Business Insider's Katie Notopoulos wrote last week, the app "feels like the future of AI we were promised" — delightful for making goofy, personal clips and "terrifying" because of how real those videos can look.
Users can also allow friends or anyone to use their likeness, which drove an early flood of meme-y clips featuring public figures and tech insiders.
That dynamic has already produced some viral moments.
OpenAI staffers, including CEO Sam Altman, were among the first to create and share their AI likenesses, and users promptly made Altman the main character of the feed's early days.

Those viral clips have ranged from joke CCTV footage of Altman stealing GPUs at Target to music videos and dinosaur cameos — all generated inside Sora 2's short-form format.
The rollout has also sparked an invite frenzy.
By October 1, Sora codes were being resold on eBay from $10.99 to just under $45, even as OpenAI warned in its Discord that selling codes violates server rules.
By October 3, Sora had climbed to No. 1 among free apps in Apple's App Store, ahead of Google's Gemini and even ChatGPT.
OpenAI has been tweaking policy as usage surges.
In a blog post last Saturday, Sam Altman said the company would give rightsholders more "granular" control over how their characters and IP can be used on the platform and floated revenue sharing for those who want their characters generated by users.
