Net non-commercial positioning is live (CFTC Commitments of Traders, weekly). CFTC’s report resolves to non-commercial / commercial, not to a dealer / fast-money / retail / passive breakdown — no holder-type share is wired, so concentration renders withheld rather than estimated below.
The long side is carried by one holder type at a majority share of open interest. A small number of accounts inside it hold most of that share.
Dealer inventory is short against it and has been reducing. The natural buyer of an unwind is the one already positioned the same way.
A reduction of the concentrated side into stable prices. That would establish depth the ladder does not currently show.
From filed position reports, exchange open interest by holder category, and the settlement records that follow them. Where a category is small enough that a single account dominates it, the desk says so instead of reporting the category.
Intent, and timing. A concentrated position says what a forced exit would cost, not that anyone is about to take one. The desk publishes the fragility and not a forecast of the trigger.
