Explore Posterior ProWhat these numbers are. Hit rate is wins over priced, settled Decisions; voids and pending picks are shown separately. ROI is net return over total flat 1u stakes at the price captured at lock from an allowlisted book — a diagnostic of the record, not a verified customer return. Settled picks without an executable price are reported as unpriced, never assumed. The current board selects market favorites the model does not dispute and is judged on hit rate; a positive ROI is reported when it happens, never promised. Individual results do not establish parlay performance.

02 / Publication discipline
Publication discipline
A prediction isn’t enough. The price has to hold up.
Posterior checks market-price evidence and publication eligibility before a Decision enters the official board. Most of what the model evaluates never becomes a pick, and that restraint is the product.
- 01
Evidence before edge
A candidate needs a two-way market anchor from allowlisted books, fresh odds, a confirmed lineup and starter, and a large enough sample. Thin, one-sided or stale prices are display-only and never publish.
- 02
The price has to hold up
The board keeps only markets whose captured price sits inside the policy’s limit against the consensus anchor. If the price drifts past that limit before lock, the row stays WAIT — it is not filed.
- 03
Filed once, graded in public
A filed Decision is immutable: the book, price, quote time, probability and policy version are frozen at lock, settled from the box score, and released to the public ledger — losses included.
Published boardNo MLB slate on the board today
There is no supported MLB slate to publish today.
One population, one lock archive: every filed Decision above was one of the assessed contracts. WAIT and PASS rows are visible in the product, never repackaged as picks. How the gates work
03 / Posterior Decisions
What a Decision actually looks like.
A settled public Decision with its filed price, probability and recorded outcome. Later market movement never rewrites the original receipt. The example is the latest released one, chosen by date — never by result.
