JRE MMA Show #185 with Ethyn Ewing · Aired Sep 2, 2026
Claim summary · not a verbatim quotation
Jose Aldo was undefeated as a champion for 10 years.
The finding
What the evidence shows
Aldo did go about ten years without a loss, from a 2005 defeat until Conor McGregor knocked him out in 2015, but he was not champion for that whole stretch. He won the WEC featherweight title in November 2009 and lost it to McGregor in December 2015, so his undefeated run specifically as champion was roughly six years, not ten.
