Altseason Scenario Model
Are the conditions in place for an altcoin season?
The index does not predict the future blindly. It measures observable conditions for altcoin rotation: technical rotation, macro liquidity, top 300 breadth, catalysts, stablecoin fuel and geopolitical risk.

The hotter the score, the more the model penalizes altseason odds because markets may prefer dollars, bonds or cash.

Editorial claims are not used as live data.

Several cards can mention the same region because each Polymarket question has a different trigger, deadline and market-implied probability.

FavorableThe higher war/escalation risk rises, the more the index penalizes altseason odds. The model now separates sudden shocks from conflicts already priced in: a local city-capture market weighs less than Taiwan, Hormuz, nuclear or oil risk.
