HYPE Markets and Data on Polymarket

HYPE trades the same instrument structure as the other archive coins — Up/Down on 5-minute, 15-minute, and 4-hour windows plus threshold lines — but as a newer listing its book history starts after the coin earned its series.

That makes HYPE a controlled study of listing ramp: the archive's earlier frames show the thin, wide books of a new instrument and the later frames show the tightening that follows, all on the same timestamp grid.

HYPE reproduces the venue's structural patterns — 98.6% of executable prices on the grid, one-sided books at 16.9% of 5-minute snapshots, 3.24% crossed — with the extra texture of launch-week thinness concentrated in its earliest weeks.

The honest lesson for a new-coin study: early books were one-sided for long stretches, and only a ladder-indexed backtest can show that fills were gappy even when the mid looked smooth.

HYPE's first threshold markets open wide, reprice violently on reference prints, and step-wise tighten as market makers join. The archive records the entire ramp at 250ms — an event-study in one query.

Pulling the series slug yields the full sequence with bid, ask, mid, depth, volume, and outcome per row, the structure needed to measure when the book actually became tradable.
