McGregor vs. Holloway Officially Set — Kalshi Market Reacts

- Dana White confirmed McGregor will fight Max Holloway at welterweight headlining UFC 329 on July 11 in Las Vegas.

- Kalshi's "McGregor fights Holloway next" contract is now the dominant bet in the series at 25,517 total open interest.

- Watch for any injury news or withdrawal before July 11 given McGregor's recent cancellation history.

UFC CEO Dana White announced on May 16 that Conor McGregor will return to the octagon against Max Holloway in a welterweight bout headlining UFC 329 on July 11 at T-Mobile Arena in Las Vegas. McGregor has not fought since breaking his leg against Dustin Poirier on July 10, 2021. He previously pulled out of both a scheduled June 2024 bout against Michael Chandler due to a broken toe and an earlier planned return in 2023 that was also shelved due to injury. He became eligible to compete again on March 20 after completing an 18-month anti-doping suspension, clearing the final regulatory hurdle for his comeback.

KXMCGREGORFIGHTNEXT-28-MHOL is the primary contract tracking whether Holloway is McGregor's next opponent. With the fight officially announced, alternative name contracts like Carlos Prates and Tyron Woodley show zero bid depth and ask prices of just around 3 cents. This reflects near-total certainty that Holloway is the confirmed opponent.

The key date is July 11, when UFC 329 is scheduled at T-Mobile Arena. Any injury report or withdrawal announcement before then could sharply move the Holloway contract downward and revive interest in alternative opponent contracts. McGregor's two cancellations in three years suggest that pre-fight health updates could be the single biggest variable.
