Postmatch editorial
Guinea flipped the prices on their head
The final score was Algeria 1-2 Guinea. It landed away from the main pre-match lean and counts as a genuine twist in the numbers.
Morlaye Sylla put the first mark on the match 50', setting the tone for the rest of the night.
The raw numbers were a little messier than the result: Algeria led Possession 66%-34%, even though the scoreboard went another way. Algeria also shaded Shots on target 5-4.
Before kickoff, our model made Algeria the likeliest result at 64.9%, while the median bookmaker line priced Algeria at 66.2% implied. On BTTS, the model leaned No (59.8%), and that angle missed.
The model still found a small price edge on X at Marathonbet. The market was offering 4.40 against a fair line of 4.09. That translated to an edge of 7.6% before kickoff. The price edge was there, but the final result did not follow it.
