What the market said before kick-off

  • ST Mirren win 13% did not happen
  • Draw 17% did not happen
  • Celtic win 70% happened
  • Over 2.5 goals 67% happened

Pinnacle closing price with the margin removed, next to what happened. It is the market's view, not a tip: an outcome priced at 30% happens about 3 times in 10.

Regular starters not in the XI

  • Kieran Tierney — not in the starting XI (started 4 of the last 5)

Not in the XI does not mean injured: it can be rotation, a suspension or a knock. We only compare with the team's last 5 line-ups.

Pinnacle, margin removed (home / draw / away): 13 / 18 / 69% when the line-ups came out, 13 / 17 / 70% at kick-off.

In the big leagues, line-up news is usually already in the price by the time it is official.

The most likely result is not the same as value: value is where a bookmaker pays more than the fair price, and the two can point to different outcomes.

Market discrepancy: before kick-off, Celtic (2) was priced at 1.51 by a soft bookmaker, above the fair price of 1.50 — a +0.9% gap. An observation about the price, not an instruction to bet.

The gap was smaller than 1.5% — likely to vanish in rounding, latency or line movement. We logged it for transparency, but it was not a strong signal.

A single result where a bookmaker pays above the fair price — separate from the main prediction below.

Model agreement High

Confidence reflects only the sharp probability of the selection: high from 50%, medium from 40%, low below. It says how likely the result is, not how big the price gap is. Model agreement shows how close our own model is to the sharp market on this selection — when it is Low, the market and our model disagree, so treat the flag with more caution.

“Detected” is the moment the flag was first shown on the site and written to our ledger (recorded live since 26 September 2026). For earlier matches the flag was reconstructed afterwards from the prices we had stored, and the time shown is when the rule would have fired: a backtest, not a live record. When the gap closes, we say so instead of pretending the value is still there.

Match context

The last 5 head-to-head meetings we tracked split 0–1–4 (ST Mirren wins – draws – Celtic wins).

ST Mirren scored 1.6 and conceded 0.6 across their last 5 matches in our results database; Celtic scored 2.8 and conceded 1.4 in 5.

Since opening around 1.53, the sharp market price on Celtic has shortened to 1.42 — the market has moved towards this outcome.

These figures come from our own tracked results and odds snapshots for this fixture — not from a generic stats feed.

Prediction hash — integrity fingerprint 18bd965e3d882827

This hash fingerprints the prediction as recorded: teams, kick-off time, our model probabilities, the Pinnacle prices recorded for it (at logging or, if there were none, the first quoted after logging and before kick-off, which can be written in after the match) and the log time. A later edit to any of them would change it (a rescheduled kick-off changes it too). It does not cover closing prices, the result or the value-bet record above; value flags recorded live have their own seal in the public record. Verify in the public record →

Every day a snapshot of the full public record is published to a public Git repository and timestamped with OpenTimestamps. Timestamped snapshots are never overwritten and the Git history shows any difference, so a later change to a past row is visible by comparing two snapshots. The corrections file lists the corrections we announced. Verify on the public log →

Since 20 June 2026 the public record is snapshotted daily (07:40 Bucharest time: 04:40 UTC in summer time, 05:40 UTC in winter) to an external log. A prediction is externally timestamped before kick-off only if it was in a snapshot taken before the match; predictions logged on match day, or whose Pinnacle price was added after logging, first appear there after kick-off. Value flags have been recorded live only since 26 September 2026; earlier value flags were reconstructed on that date.

Methodology

The fair price comes from the sharp market itself: we strip the margin from Pinnacle-style odds — the most accurate public predictor in existence — and use our calibrated Elo + form model as a cross-check and as the fallback where no sharp price exists. Value is flagged only where a softer bookmaker prices a selection above that fair price, never on long shots (implied probability under 30%), and never beyond a plausible band. Most of the time there is no value — and we say so.
