The analysis

Claude
Charles Jourdain by Decision, 62% confidence

This is the clearest model-vs-market tension on the card. Elo still favors Vera 57-43 because his rating was built against O'Malley, Sandhagen, Figueiredo and Munhoz, but the -37 recent trend tells the real story: four straight decision losses, the last two to Aiemann Zahabi and David Martinez, fighters a peak Vera would have been favored over. Vera's career numbers already show a negative striking differential (4.18 landed vs 5.34 absorbed) and that gap has widened as his notoriously slow starts have turned into slow full fights; he has zero finishes in his last five. Jourdain, by contrast, is 3-0 since dropping to bantamweight with two first-round guillotines and a unanimous decision over Kyler Phillips, a legitimately ranked opponent. He outlands his opponents (5.36 SLPM vs 4.11 absorbed) with a 56% defense rate that beats Vera's 50%. The common opponent (Davey Grant) favors Jourdain on method: he choked Grant out in one round where Vera needed a decision. Jourdain's 46% takedown defense is the exploitable hole, but Vera attempts only 0.47 takedowns per fight and has never been a wrestler-first fighter, so the hole is unlikely to be tested. Vera's durability (never stopped in 25 UFC bouts) and his 0.8 sub average make him a live dog if Jourdain gets reckless on the feet or dives on a guillotine that isn't there, which is why this is not above 62. I side with the market's Jourdain lean over the Elo prior, but at 62 rather than 68: the Elo still captures something about Vera's floor and late-round surges that the market may be over-discounting. Expect Jourdain to bank rounds one and two on volume and Vera to rally too late.

Charles Jourdain by Decision, 64% confidence

Jourdain's higher striking output, better defense and positive strike differential favor him in a predominantly standing fight. Vera has a grappling opportunity against Jourdain's 46% takedown defense, but his low takedown rate limits that advantage. Missing recent form and reliable finishing data temper confidence; the decision pick assumes three rounds.
