The 73.5% implied probability for an unbeaten World Cup champion stems primarily from the depth and consistency of leading contenders heading into the expanded 48-team format. Top squads have demonstrated strong recent form in qualifiers and international windows, with minimal losses and solid defensive structures that favor clean sheets or draws in group play. Key player availability remains high following domestic seasons, reducing early injury risks that could disrupt momentum, while historical tournament patterns show favorites often advancing through knockout rounds without defeats. Traders appear to weigh these factors against the potential for upsets in a larger field, resulting in the current consensus pricing.
