NegRisk arbitrage

STRUCTURAL sum of YES bids > $1 → buying every NO locks in profit regardless of outcome.  VERIFY sum of YES asks < $1 → only an arb if the outcome list is exhaustive — the gap usually prices "winner not listed".

Near-resolution board (94–99.5¢)

High-probability markets close to their end date. Not free money — the discount is usually the genuine tail risk. Edge exists only when the outcome is already decided and the market hasn't caught up.
