The market has Smith at 66% de-vigged. Elo has him at only 53%, but his rating is provisional (2 rated UFC fights), so it understates a prospect who is still rising (+40 trend). The gap between the two priors comes from Smith's small sample, not from evidence against him, so I stay near the market with slight caution. Smith is 24 and 4-0 since his Contender Series fight: decisions over Aaron Tau and Vince Morales, a slam TKO of Kazama, and a rear-naked choke of SuYoung You. That shows growth into finishing in all phases. Grant turns 41 next month. He is a durable, high-volume decision fighter (4.77 strikes landed per minute) whose last four wins all went to decision. His 61% takedown defense is a weakness against Smith's 2.98 takedowns per 15 minutes at 53%. Grant was also choked out by Jourdain in round 1 in 2025, which shows submission vulnerability in scrambles. Grant does have real edges. His strike defense (55%) is better than Smith's (46%), and he can win a three-round volume fight if Smith's wrestling stalls. That keeps Grant live as an underdog. Grant is hard to finish, so a Smith decision built on takedowns and control is the most likely result. A late submission is the second-most likely.

Smith starts at the supplied 66% market probability. His higher takedown rate and accuracy offer a credible route against Grant's 61% takedown defense, with submissions providing another threat. Grant's higher striking volume and stronger striking defense keep this competitive. Elo favors Smith only 53%; its provisional two-fight sample limits its weight, but the disagreement and inconsistent fight logs justify trimming confidence to 64%. Smith's recent finishes support his grappling threat without establishing superiority against stronger opposition. Grant's recent decision wins favor a distance outcome. Reported layoffs of 190 and 232 days are below the material-risk threshold. Method percentages are conditional on Smith winning.
