Index-Inclusion Committee Rule Model

Index additions look discretionary but run on published eligibility rules — profitability tests, float thresholds, seasoning periods, sector balance — and a committee that follows them closely. You maintain a scored candidate list against the actual rulebook, watch the quarterly rebalance calendar, and trade inclusion markets where the crowd is backing a famous name that fails a specific criterion. Ineligibility is often the whole trade, and it is checkable in advance.

What you need to run it

Current index methodology document and a screener implementing each criterion
Rebalance calendar with announcement and effective dates
Float, liquidity and profitability data current enough to test eligibility

Where this applies

Markets on Polymarket where index-inclusion committee rule model is the natural play:

Will this company be added to the S&P 500 this quarter?
Will Coinbase join the Nasdaq-100 in the next reshuffle?
Will any new company enter the Dow Jones in 2027?
