Who will win Merida vs Medvedev?

Critical divergence points:

• Polymarket (Completed Match): Binary completion-only market. Resolves YES only if match is played to full completion under normal play rules. Resolves NO for any non-completion outcome including retirement, default, disqualification, walkover, cancellation, or delay beyond 7 days. Key Quote: 'This market will resolve to "Yes" if all games and sets required to determine a match winner under governing body or event organizer rules are played to completion through normal play. Otherwise, if the match is not completed for any reason, it will resolve to "No."'
• Polymarket (Winner): Winner market with walkover carve-out. Resolves to advancing player if match begins but is not completed due to retirement/default/disqualification. Resolves 50-50 if walkover occurs before start, match is canceled, or delayed beyond 7 days without winner. Key Quote: 'If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 50-50.'
• Kalshi: Simple binary winner market. Resolves YES if either player wins after a ball has been played. No distinction between normal play and forfeiture methods. Does not address walkover, cancellation, or delay scenarios. Key Quote: 'If Daniel Merida wins the Merida vs Medvedev professional tennis match... or if Daniil Medvedev wins... then the market resolves to Yes.'
• Limitless: Winner market accepting all official declarations. Resolves to the player officially declared winner by governing body, including walkover, retirement, withdrawal, default, or disqualification. No carve-outs for forfeiture methods. Key Quote: 'For the purposes of this market, a player officially declared the winner of the match will be considered to have defeated the opponent, including in cases of walkover, retirement, withdrawal, default, or disqualification.'
