At UFC 315 in Montreal, social media personality Stephen Deleonardis, better known as SteveWillDoIt, saw his massive $600,000 parlay bet collapse in dramatic fashion when welterweight champion Belal Muhammad lost his title to Australian challenger Jack Della Maddalena.
“Overall you’re the last leg of my parley don’t f*** this up I win 600 overall don’t f*** this up win my parley,” SteveWillDoIt can be heard saying in a video shared on social media, placing his hopes on Muhammad retaining his championship belt.
Those hopes were dashed when Maddalena put on a striking clinic against Muhammad, earning a unanimous decision victory with judges’ scorecards reading 48-47, 48-47, and 49-46. The Australian’s superior striking rhythm and defensive wrestling proved too much for the now-former champion.
The high-stakes bet became a talking point across social media platforms, with fans expressing shock at the enormous sum wagered on what turned out to be a competitive and unpredictable championship bout.
Muhammad, who had spoken openly about his desire to build a legacy comparable to welterweight legend Georges St-Pierre, faced a determined Maddalena who entered the octagon with a seven-fight UFC winning streak. Despite Muhammad’s impressive résumé that includes victories over Leon Edwards, Gilbert Burns, and Stephen Thompson, he couldn’t overcome the challenger’s precise striking and takedown defense.
The five-round battle saw Maddalena grow increasingly confident as the fight progressed. While Muhammad attempted to implement his wrestling-heavy game plan in the later rounds, securing a takedown in the fifth, he couldn’t maintain control or inflict enough damage to sway the judges.
For SteveWillDoIt, the outcome represents one of the most expensive gambling losses publicly documented in UFC betting history. Known for his extravagant lifestyle and willingness to make bold wagers, this particular bet will likely be remembered as a costly miscalculation.
The championship bout itself was a technical masterpiece, with both fighters bloodied and exhausted by the final bell—a display of heart and skill from two elite welterweights. Unfortunately for Muhammad and his high-rolling supporter, it was Maddalena who left Montreal with the championship gold.
SteveWillDoIt’s massive financial loss serves as a stark reminder of the unpredictable nature of combat sports, where fortunes can change with a single punch, kick, or judge’s scorecard.
