UFC Fight Night trading preview
Arnold Allen won 19 of his first 20 professional fights, including his first 10 in the UFC, before a loss to Max Holloway in April 2023 started a 1-3 stretch. The 32-year-old returned to the octagon at January's UFC 324 after missing 17 months with a shoulder injury, followed by some mental health struggles stemming from the injury and rehab. Allen lost his return fight to Jean Silva by unanimous decision, but Allen is still ranked in the top 10 (No. 7) for UFC featherweights.
While Allen is fighting to maintain his position toward the top of the division, the 29-year-old Melquizael Costa is out to prove he deserves to be thought of even higher. Costa's been one of the busiest fighters in the UFC since the start of 2025, with Saturday marking his sixth fight in 15 months. No. 12-ranked Costa has won all five of those bouts, improving his UFC record to 7-2 and professional mark to 26-7. Costa can win in a variety of ways, with his last six wins evenly split (two by KO/TKO, two by submission, and two by decision).
For UFC trading, Allen is priced at $0.53 per share to win, while Costa is priced at $0.47 per share. Other fights to watch for on Saturday's UFC Fight Night include Daniel Santos ($0.61 per share) vs. Dooho Choi ($0.39) and Malcolm Wellmaker ($0.72 per share) vs. Juan Diaz ($0.29 per share).
