Fading fresh listings
A 27,000-listing calibration study found brand-new markets systematically mispriced by band: mid-priced listings too rich, favorites too cheap. The executable follow-up looked like the best thing on the board at 29 settlements (+53.6%) — and read −15.2% at 289.
The hypothesisA market's first posted price is one person's guess, not a crowd's. If listing prices are systematically biased — too confident in the middle, too timid on favorites — then trading against the bias in a listing's first minutes, before the crowd arrives, is an edge with a built-in exit as prices converge.
The test
First the measurement: every new listing's initial price archived since January (~27k with resolutions) against what actually happened. The bias is real and band-shaped: non-crypto listings priced 30–70¢ resolve YES several points less often than their listing price implies (the worst decile band: −4.9¢), while 80–97¢ listings are slightly cheap; crypto listings are efficient from the first print and excluded. The live probe then trades the bias where it must actually be harvested: at the live ask within 45 minutes of listing, with strict spread and premium gates — fresh books are thin, and the measured edge is only a few cents, so overpaying the gate would eat it. Two lanes (fade the middle, back the favorites), settled at resolution net of fees.
The result
The verdict gate did its job — just not the way the early numbers suggested. At 29 settlements the FADE lane sat at +53.6% ROI-at-ask, one entry from its gate and the most promising thing on the board. Three weeks and 260 more settlements later it reads −15.2% over 289 settled (101 wins). The calibration bias in indicative listing prices is real and still visible in the archive; the executable version of the trade — crossing a thin fresh book within 45 minutes of listing, even under a 2¢ premium gate — pays more in entry cost and adverse fills than the 2–5¢ mid-band bias is worth. The favorites lane settled 31 entries at +1.8%: market rate, no edge.
The early +53.6% was twenty-nine mostly-small wins arriving before the first cluster of losers — exactly the sample at which strategy posts declare victory, and exactly why the gate exists.
Conclusion
Negative, and instructive about gates: a 30-entry gate is a filter against noise, not a certificate, and this lane passed through it on luck and failed on sample. Listing-price calibration joins the list of edges that live in indicative data and die at the ask. The calibration table remains useful as telemetry about how creators misprice; the executable probe was retired on 2026-08-21.
