The Gap #11: the book and the crowd disagree on Escarrega, Fabrizio vs Alsaghir, Abe

Prediction markets and crypto books disagree most sharply on a pair of UFC undercards this week, with one gap wide enough to warrant a proper look.

The fights

The standout number in this issue is Fabrizio Escarrega against Abe Alsaghir on 12 August. Polymarket's crowd sits Escarrega at 59.8% to win; Cloudbet, with the vig already stripped out, implies only 52.9%. That 6.9-percentage-point gap is the largest we're tracking this week by some distance. In money terms, the crowd's fair price on Escarrega is 1.67, yet you can get 1.80 at Cloudbet right now — roughly 13 cents on the decimal above what the market thinks is fair. That's not a paper edge; it's a meaningful one, and it's the lead item for a reason.

Second in line is Joe Kropschot to beat Jon Kunneman, also on 11 August. Polymarket puts Kropschot at 27.4%, while Cloudbet's stripped implied probability lands at 22.7% — a 4.7-point gap. The crowd's fair price is 3.64; the book is offering 4.18. Kropschot is the underdog here and the edge is real, though position sizing should reflect the lower win probability. Two meaningful gaps on the same card is unusual enough to pay attention to.

Neil Magny to beat Ramiz Brahimaj on 15 August shows a 2.3-point gap — Polymarket at 49.5%, BC.Game stripped to 47.2%, with a book price of 1.98 against a fair price of 2.02. That's the thinnest category of actionable, and only worth considering if you have strong conviction beyond what the market is pricing. Everything below that number this week falls into territory we'd rather be honest about.

The skips

Several names you'll recognise make this section necessary. Islam Makhachev to beat Ian Machado Garry is the main event on 16 August, and yes, the crowd is 75.2% confident — but the gap against Stake's stripped number is only 1.7 points, which is no edge. Mackenzie Dern at 1.3 points, Esteban Ribovics at 1.2 points, and Anthony Wint at 1.2 points are all in the same bracket. Vicente Luque to beat Tresean Gore shows a 1.8-point gap with a crowd fair price and book price both sitting at exactly 2.20 — by definition, there is nothing to take. Ananias Mulumba and Mridul Saikia both land at 1.8 points as well. None of these cross the threshold. The Rodrigues-Hernandez line actually runs the other way, with the book implying a higher probability than the crowd, which is a different kind of signal but not one we'd chase here. If the gap isn't there, the bet isn't there.

Odds move between capture and kick-off, and the price at the book when you place it is the only price that matters.
