Switzerland's consistent qualification success, including an unbeaten UEFA campaign, combined with higher FIFA ranking and experienced roster depth, drives the 51.5% implied probability as group favorites despite the absence of veteran Xherdan Shaqiri. Canada benefits from co-host status and home matches in Toronto and Vancouver at 29%, though recent form has shown defensive vulnerabilities and limited attacking output in preparatory fixtures. Bosnia and Herzegovina's 17.5% reflects their dramatic playoff qualification and return to the tournament after over a decade, creating underdog momentum in a mixed-confederation group. Qatar trails at 2.3% following a disappointing 2022 showing and limited recent competitive edge against European sides.
