UFC 329 sees the return of McGregor vs Holloway as the main card event at the T-Mobile Arena in Las Vegas this Saturday (July 11th), a welterweight rematch years in the making, and prediction market apps have the event live.
The origins? Snap back to 2013, and a young McGregor defeated 21-year-old Holloway in a featherweight bout by unanimous decision. Fast forward to today, and they’re both legends in their own right; albeit this is McGregor’s first return to the octagon since his 2021 leg injury loss to Dustin Poirier. So, will the ring rust show? Here’s more.
Best prediction market apps for UFC 329 McGregor v Holloway
UFC 329 sees a return of two legends; McGregor v Holloway 2.0, and the rivalry is years in the making. They first met in the featherweight class (in 2013), where McGregor won by unanimous decision against a young Holloway, and they stand as legends, in one of the most anticipated bouts; even prediction markets, like Polymarket and Kalshi, have the event contracts live, with crowd sentiment favoring a win for Holloway at 64-66%+, vis-à-vis McGregor at 35-36%+.
So, are the odds stacked against the former champ? Let’s take a look at both sides. On one corner, the accolades for McGregor speak volumes. The Irishman, now turning 38, is the former UFC featherweight and lightweight champion. He has fought all the greats, like Khabib, Dustin Poirier, and Floyd Mayweather, albeit rusted, now five (5+) years from the octagon. Plus, he’s moving from featherweight to welterweight, too. Cue Holloway, the former UFC featherweight champ with a dominant “BMF” titleholder reign; he comes in as the favorite on sports prediction markets, and it’s not for naught.
He has been at it for a while now (with no breaks), and his elite cardio, high-volume striking, and grappling are likely to put McGregor through the paces. That’s compounded by his recent form, winning against the likes of Justin Gaethje. Here are the best prediction market apps where you can catch the bout.
