What were the last available Washington Nationals vs. St. Louis Cardinals (2:15 PM ET) odds?

No historical prices are available on this page. The last available price is not necessarily the final settlement price.

Why do Washington Nationals vs. St. Louis Cardinals (2:15 PM ET) odds vary across prediction markets?

How do Washington Nationals vs. St. Louis Cardinals (2:15 PM ET) prediction market payouts work?

For example, a 40¢ price implies about a 40% chance. For a standard $1 contract, a share pays $1 if its outcome settles as correct and $0 if it settles as incorrect.
