What the market said before kick-off

  • Cobresal win 27% happened
  • Draw 27% did not happen
  • Coquimbo Unido win 46% did not happen
  • Backtest flag (reconstructed afterwards, not recorded at the time): 2 · Coquimbo Unido @ 2.22 (Betano) Lost

CLV +1.7% vs the fair close. One flag on its own says little; the rule is judged on all of them.

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

  • Cristián Zavala — 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): 27 / 27 / 46% when the line-ups came out, 27 / 27 / 46% at kick-off. The price barely moved after the line-ups.

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, Coquimbo Unido (2) was priced at 2.22 by a soft bookmaker, above the fair price of 2.20 — a +1.1% 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.

“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.

Prediction hash — integrity fingerprint e56dfa1f2c486fdf

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.
