Posterior is an independent baseball market almanac, built and operated in eastern Ontario. The model is a hierarchical Bayesian system fit nightly, calibrated against recent resolved entries by three competing scalers (isotonic, Beta, BBQ), de-vigged against sharp market consensus, and surfaced as a daily slate of player-prop entries with transparent probability, edge, and grading context.
The work is published under the Posterior Research Desk, the editorial identity of ekkOS Technologies Inc.
The record is open. The full methodology is published, and the delayed resolved model ledger lives at /data — wins and losses both. No black box. No cherry-picking. No tipster culture. Live rows, pending rows, calibration dashboards, and full internals stay inside the subscriber almanac and API.
The legal entity is ekkOS Technologies Inc. Posterior is built as an editorial almanac: predictions, team desks, league tables, source-linked news, and a public record designed to be checked rather than trusted blindly. Drawn deliberately, restrained on purpose.
Posterior holds no affiliation with any sportsbook, exchange, or licensed betting operator. Subscription revenue is the only revenue. There are no affiliate links, no white-labeled comparisons, no paid placements. If gambling has stopped being entertaining for you, call 1-800-522-4700 (US) or 1-866-531-2600 (Canada).
