The Ladder: what closes, what publishes, and where the open interest sits, on one date axis.
Display
Capital in an event contract is locked until the contract
stops. One date axis, three readings: what closes, what an agency publishes
that day, and where the money is parked.
LADDER · CLOSINGS
How many markets close on each of the next fourteen dates
These counts group open markets by their trading close date in UTC.
Closing stops trading; resolution and payment can happen later.
A close date does not establish when capital returns.

The counts fill from one read of
the open catalogue when this page loads. No count is baked into these bytes: a
build-time figure would be stale by however long they sat on the host.[SERVED · 5M]
LADDER · RELEASES
22 of 96 settlement days also carry an official release
Macro contracts settle against numbers the statistical agencies publish on
dates they announce a year ahead, and those schedules are public domain as
works of the US government. Laid over the maturities in the panel below, they
say which days carry both at once: a contract stopping and a number landing.
3 of the ten heaviest settlement days fall on a day
one of the schedules below names a release. The join is on the date alone, and
both sides come from a publisher.
Settlement population: report 2026-09-08; 131,886 rows, 131,886 symbols. Calendar checks do not refresh this population.
The heaviest settlement days, and what the agencies publish that
day. Counts are markets maturing; “no scheduled release” means the
schedules named below carry nothing that day.

a maturity date is when the contract STOPS, not when the venue pays: settlement can follow. And this is one report date, so a market listed after it is not in this calendar at all
