Elon Musk and Mark Cuban Not Betting on Super Bowl LVIII

Elon Musk and Mark Cuban are far from friends, but they are united on one front, that's NOT betting on Super Bowl Sunday ... because, as you might've figured, they're not big on burning money.

TMZ reached out to both mega billionaires days leading up to the big game, and we got shockingly similar responses from each guy -- no, they won't bet on the Super Bowl ... and, in fact, they say they don't bet on sports at all.

Elon tells TMZ there are "plenty of other risky things going on" ... so it sounds like he might be taking other risks with his cash -- he did gamble $44 billion on X (née Twitter) after all.

As for Mark ... he told us he's not allowed to bet on NBA games because of his ownership stake in the Dallas Mavericks. While he doesn't know if that betting extends to the NFL, he'd rather skip any "potential hassle" altogether. Smart move.

Cubes noted that betting money, IF you can afford to lose it, can be fun and the uber-competitive billionaire does love to win ... it's just not something he'll be doing on Sunday.

MC also tells us he's not attending the Super Bowl, but he'll be watching and rooting for the Chiefs ... unsurprising, given how complimentary he was of Taylor Swift and Travis Kelce's relationship when news of it first broke.

BTW ... Elon and Mark being aligned on anything is pretty wild news in and of itself -- they've been in a very public feud, with Elon calling Mark a "racist" last month for supporting diversity, equity, and inclusion hiring practices and challenging him to a MMA fight.

Cuban defended his stance on DEI, and called X Elon's "little echo chamber" ... a savage blow, considering Musk touts the platform as a paragon of free speech.

Bottom line, Musk and Cuban are saving their money this Super Bowl Sunday -- bad news for bookies, no doubt.
