The other candidate moves are 40. Qd8 and 40. hxg4
The conditional market for the other moves are here:
The market value (averaged over the last 4 hours before close) of this market and the other markets will be measured. If this market has a higher (last-4-hour-average) market value, it will resolve to the score after move 41, otherwise it will resolve N/A. Note that "Market value" and "Score" do not work on the same schale.
Here is a table of the correspondence to market value and score for the current move which will be used to calculate PROB from this score:

This correspondence is defined by linearly interpolating between the points
(0.0, 0.0), (0.1, 0.82), (0.9, 0.98), (1.0).
The score after move 41 is the score (not market value) of the winning move in move 41.
It might have a different function to calculate scores from market values: The function assigns score z to 50% market value, z+0.08 to 90% market value and z-0.08 to 10% market value, where z is the (rounded) score after move 40, but at most 0.9 and at least 0.1. Note that when the game ends, the score will be 1.0 - #moves x 0.0004 if white wins, 0.5 - #moves x 0.0002 if its a draw, or 0.0 if we lose.

@harfe I think I understand as the game ends there will be two different score computations (the values may or may not coincide), but still seems worth clarifying:
For the “score after move n” where n is the last move, that move’s winning conditional market’s last 4 hours average probability will determine that score, applying the leveraged transformation. That value, deleveraged, will be used to resolve the winning conditional market for move n-1.
Then that final move’s winning conditional market —which will be titled something like “If we play <n. xx>, what is the score after move <n+1> (leveraged)?”— will resolve by deleveraging the special game ending score (1-n*0.0004 if white wins), since there is no move n+1.
Also worth mentioning, though it’s pretty clear from its description, the main game market simply resolves to either YES or NO or 50%. The final score, or scores, or any other computations have absolutely no bearing on that market’s resolution, only the game’s result will.
BTW I’m mindblown that some guy in the late ‘70s already knew The Answer to this n thing. 😄
