We currently have two World Champions on RAW and Smackdown with lengthy Title reigns. Brock Lesnar has held the WWE Universal Championship for over 470 days. AJ Styles has now held the WWE Championship for over 250 days.
A pretty cool stat to pass your way about their Title reigns.
It turns out that this is only the second time in WWE history that two World Champions have had Title reigns of 250 days or longer (at the same time). The only other time it happened was back in 2005 where Cena held the WWE Title and Batista held the World Heavyweight Championship:
Both @WWE Champion @AJStylesOrg & Universal Champion @BrockLesnar currently have reigns of 250 days or more.
The only other time in #WWE history that 2 world champs had 250+ day reigns at the same time: 2005, when @JohnCena was WWE Champion & @DaveBautista held the World Title.
