NFL 2026 Observed partial coverage

Declared season scope; individual event-to-season mapping is unverified. This is not a complete-season archive.

UTC timestamps retain their recorded precision; dates alone identify UTC days. Vintage, observation and sports event times are separate. Capture time does not establish exchange quote freshness.

Why the capture contract matters

Venue APIs expose useful live books, trades and price history, but they do not serve the same historical snapshot and game-context archive packaged here. Data that was not recorded during the live window cannot be recreated from a current-book endpoint later. The exact fields, cadence, venue coverage and limitations vary by product, so this page and the shipped documentation state the contract explicitly instead of calling every file complete or tick-level.

What's in the dataset

Dated snapshot: 95,131,459 depth rows · 4,930,845 trade prints · 100,062,304 total rows · book samples 2026-06-28T16:10:43Z through 2026-10-02T23:59:16Z · artifact vintage 2026-10-02; separate from observation times

✓ Dated snapshot: 95,131,459 depth rows · 4,930,845 trade prints · 100,062,304 total rows · book samples 2026-06-28T16:10:43Z through 2026-10-02T23:59:16Z · artifact vintage 2026-10-02; separate from observation times
✓ Sampled L2 depth for NFL game, spread, total, half and team-total markets, up to 20 levels per side. The manifest gives the depth and captured-print counts, separate observation and exchange-time bounds, and measured intervals for this version. Depth is the sport's share of a global volume-ranked poll; lower-volume markets can be absent while open. A zero print count describes this recorder's coverage, not whether the exchange publishes trades. OBSERVED_GAPS.csv reports intervals between observed slice timestamps, not confirmed collector outages or continuous coverage for each market. Historical depth sizes captured through July 19, 2026 had already lost fractional precision; rebuilding cannot restore it.
✓ Version-specific observation gaps are documented in the delivered archive; missing observations are not proof a market was closed. Displayed quotes are observations, not proof of executable fills.

Research uses for this dataset

Kickoff-week repricing

Align NFL game, spread and total ladders with your own play-by-play feed to measure how displayed depth reprices through scoring drives at ~43 s cadence.

Book + prints in one join

Pair sampled depth with deduplicated NFL prints (taker side, capture-time game state) to study fills against displayed liquidity instead of quotes alone.
