The 2026 technical regulations, featuring revised power units with greater electric deployment alongside active aerodynamics, have introduced significant unknowns that compress the field for Baku's opening practice session. As a street circuit blending ultra-long straights with low-grip, tight corners and heavy braking zones, the layout demands precise setup compromises that evolve rapidly with track rubbering-in. Williams' planned major car overhaul arriving this weekend adds another variable, while wind off the Caspian and potential early-session graining further heighten unpredictability. These factors sustain the tight clustering of implied probabilities, reflecting traders' view of FP1 outcomes as highly session-dependent rather than reflective of outright pace hierarchies.
