The whole index in one position
One contract instead of a basket: this follows SPDR S&P 500 ETF Trust directly, with no rebalancing and no expiry.
It keeps trading outside regular hours, so a move that starts overnight is priced here first rather than at the next open.
Open interest
$779.1K — the money still on the table. Volume says how much changed hands; this says how much has not left.
Funding
Right now it is positive, so longs are the crowded side and they pay shorts.
