An economic event can have several published estimates without representing several different quarters. The U.S. Bureau of Economic Analysis explains that quarterly GDP is released in advance, second and third vintages. If a two-outcome proposition depends on that statistic, its terms must identify which published version supplies the observation. BEA: GDP release additional information, successive estimates

WFN analysis: suppose an invented advance GDP growth estimate is 1.9% and a later estimate is 2.1%. Against an assumed threshold of 2.0%, the observations fall on different sides. This example does not report a real quarter’s figures. It illustrates why the phrase GDP exceeds 2% is incomplete without the release and measurement conventions. An invented proposition based on the first published advance estimate would ask one question. A proposition based on the later third estimate would ask another. A subsequent statistical revision does not, by itself, determine whether a previously settled contract must be reopened. That procedural question requires the venue’s actual finality, correction and revision provisions. The growth measure is equally important. A quarter-on-quarter annualized real-growth rate, an unannualized quarterly change and a year-over-year comparison use different intervals or transformations. A short label such as GDP growth can hide those distinctions. A reproducible proposition names the intended measure along with the reference quarter, source and release vintage.

Retain the designated release document and timestamp, the reference period, measure label and originally published value. Keep later revisions in separately dated records. For a settled contract, add the actual specification, observation cutoff and any correction process. Replacing an earlier release file with a newer download can erase the information needed to reconstruct the question originally tested. BEA’s publication process explains why estimates can change as information improves. It does not supply an unnamed venue’s settlement policy. This article uses that real statistical framework to clarify a hypothetical event design. No current GDP value, actual event contract, quoted probability or settlement dispute is reported; the focus is keeping the designated data vintage visible and verifiable.
Successive estimates use progressively fuller information
BEA says the advance estimate is normally released near the end of the first month after the quarter and uses incomplete or revisable source data. The second and third estimates normally follow near the end of the next two months, incorporating more detailed and comprehensive information. The reference quarter remains the same.

The SEC/CFTC investor alert describes a binary option through a yes-or-no proposition and its predetermined cash-or-nothing payout. Applying that definition to a statistical release does not automatically choose a GDP vintage, growth measure or revision policy. Those details belong in the actual contract specification.

One quarter can produce different threshold comparisons

Separate the statistical record from the contract record
