Geopolitics & World · Arbitrage#273

Nested-Deadline Coherence Arbitrage

Geopolitical questions get listed at several horizons at once: will this happen by June, by September, by December. Those are nested — anything that happens by June has also happened by December — so the prices must rise with the horizon. Long-dated legs are thin and stale while the near-dated one reprices on every headline, which regularly pushes the set into impossibility. You buy the underpriced longer horizon against the overpriced shorter one.

What you need to run it

Grouping of markets into nested-deadline families for the same underlying event
Monotonicity checks across horizons with alerting on violations
Patience and capital, since the lock resolves only at the longest horizon

Where this applies

Markets on Polymarket where nested-deadline coherence arbitrage is the natural play:

Will a ceasefire be in place by September 30, 2026?
Will a ceasefire be in place by December 31, 2026?
Will a peace agreement be signed before July 2027?
