Wide spread — 100.0¢
Bid-ask spread is wide enough that intraday moves overstate any tradeable advantage. Most of the headline pp move would be eaten by spread on a market order.

Market Description
This is a market on who will win the upcoming World Chess Championship 2021 to be held in Dubai, United Arab Emirates between November 24th 2021 and December 16th 2021. The defending Champion Magnus Carlsen is playing the Challenger Ian Nepomniachtchi. The match is 14 games and the first player to 7.5 points will be the Winner in this market. If after 14 games, the match is equal at 7.0 points to each player, then the winner of the tiebreaks will be the Winner in this market. If the event is canceled both positions will pay out $0.50. If either player withdraws for any reason, the replacement will take the place of the player they are replacing in the market. For example: If Ian Nepomniachtchi withdraws and his replacement goes on to win the tournament, then this market will resolve $1.00 to Ian Nepomniachtchi. In the event of ambiguity in terms of the market outcome, the market will be resolved at the sole discretion of the Markets Integrity Committee (MIC).
