In early 2012, Caio was signed by the UFC. He was set to make his debut against Fabio Maldonado at UFC 142, but an injury forced his opponent from the fight. He would instead make his debut five months later against Buddy Roberts at UFC on FX: Johnson vs. McCall. Magalhaes was overmatched standing and was unable to secure consistent takedowns due to fatigue which led to a unanimous decision loss. He was next set to face Michael Kuiper as a late replacement but shortly after agreeing to the bout, he pulled out due to injury. He would return exactly one year after his first UFC fight. He faced Karlos Vemola at UFC on Fuel TV: Nogueira vs. Werdum. Although he did poorly in the first round, he was able to secure a rear naked choke in the second round to secure his first UFC win. He next was slated to take on Nick Ring at UFC Fight Night 33. He would pick up a unanimous decision victory after controlling the wrestler on the ground for the majority of the second and third rounds.
