Where the biggest money sits

Positions below are valued at the current price. Amounts are share counts; each winning share redeems for $1, so "at risk" is shares times price. Parked capital priced at 95¢ or higher and identical-size positions spread across every outcome of one event are excluded, because those are market-making rather than directional bets.
