The fragmented run plans typical of FP3 on Baku’s demanding street circuit drive the tight market across more than a dozen drivers. Teams prioritize setup validation, long runs, and tire evaluations over outright pace on the 6 km layout blending a 2 km straight with tight 90-degree corners and limited runoff, where wind off the Caspian Sea and rapid track evolution can shift grip levels dramatically within the hour. Recent form from the Spanish Grand Prix offers limited guidance, as session-specific factors like fresh soft-tire timing and minor traffic often decide the quickest lap. This setup uncertainty sustains competitive implied probabilities, with no single driver holding a clear edge heading into the session.
