Is O’Malley an Irish name?

Origin of the surname O’Malley

• O’Malley is an Irish surname derived from the Gaelic Ó Máille, meaning “descendant of Máille” (Wikipedia).
• It is historically associated with County Mayo in western Ireland.

Connection to Irish heritage

Despite his Montana upbringing, Sean O’Malley’s surname links him to a deep Irish lineage. The O’Malley clan was a powerful seafaring family in medieval Ireland.

Who is the richest guy in the UFC?

Current richest UFC fighter

• Conor McGregor is widely considered the wealthiest UFC fighter, with an estimated net worth exceeding $200 million (Wikipedia).

Top wealth rankings

Other wealthy fighters include Georges St-Pierre (estimated $30 million net worth), Khabib Nurmagomedov ($40 million), and Brock Lesnar ($25 million), but McGregor’s earnings from boxing and business ventures put him in a different tier.

For O’Malley, the gap is stark: his estimated $4 million net worth (MARCA) is a fraction of McGregor’s fortune, but his $3 million paycheck at UFC 306 (MARCA) shows he is among the higher earners in the bantamweight division.

For the UFC bantamweight division, O’Malley’s next fight will determine whether he climbs back into title contention or settles into a gatekeeper role. The choice is clear: adapt to pressure fighters like Dvalishvili, or risk being passed by younger contenders.
