In plain terms

When Polymarket says it's more likely than not that the CEO will leave by date Y, short the stock through resolution. Markets price in the imminent-departure premium before it happens.

How it works

When a polymarket on 'Will <CEO/CFO/Exec> leave <company> before <date>' has YES probability > 0.5, the underlying equity tends to under-perform through the resolution window. Two channels: (1) information asymmetry — prediction-market participants may have read-through that the sell-side hasn't priced; (2) imminent-event risk premium — once YES exceeds 50%, the equity trades at a discount even if the departure ultimately doesn't happen.
