What Could Shift These Odds Before Match Time

Court surface familiarity, recent warm-up tournament results, and late-breaking injury reports could move these numbers sharply. If either player shows rust or physical concerns in the days before, match-duration markets may compress. Conversely, confirmation of peak conditioning or a strong lead-up performance could pull traders toward longer-match scenarios. The Polymarket board remains active; monitor shifts in Set 2 markets (both at 50% implied) as barometers of confidence in reaching later stages.
