Trader consensus prices Lewis Hamilton and Kimi Antonelli as virtual co-favorites for Miami Grand Prix Practice 1 fastest lap, with probabilities tightly clustered from 25.5-30% across the top field, highlighting the session's inherent volatility on the low-grip Miami International Autodrome street circuit. Antonelli's surging form—capped by his maiden F1 win and sprint pole prior to the unexpected pre-event break—fuels his 29.5% implied probability, as he arrives declaring himself "feeling stronger" amid Mercedes' intra-team battle with George Russell. Hamilton's slight 30% edge stems from his proven single-lap prowess in qualifying simulations on soft tires and clean air runs, while midfield challengers like Pierre Gasly, Gabriel Bortoleto, and rookies such as Isack Hadjar and Oliver Bearman cluster at 28.5%, reflecting upgrade packages and track evolution potential that often yield surprises in this 90-minute opener before sprint qualifying.
