The sharp market makes Sporting CP the most likely outcome at 85% — fair odds of 1.17. Matchbook offers 1.25, a market gap of +6.5% above the fair price, which is where we flag value (Strong value). Confidence is High and model agreement is High. Recent form — Sporting CP: WWWDW; Nacional: LLWDW.
Market discrepancy: Sporting CP (1) is priced at 1.25 by a soft bookmaker, above the fair price of 1.17 — a +6.5% gap. An observation about the price, not an instruction to bet.
A single-outcome value bet — separate from our safe prediction below.
Confidence reflects the sharp probability and the size of the price gap. 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 when we logged the opportunity before kick-off — not the theoretical first second it appeared. Sharp and soft odds are tracked from our snapshots; when the gap closes, we say so instead of pretending the value is still there.
The last 5 head-to-head meetings we tracked split 5–0–0 (Sporting CP wins – draws – Nacional wins).
Sporting CP scored 3 and conceded 1 across their last 5 matches in our results database; Nacional scored 1.6 and conceded 1.2 in 5.
These figures come from our own tracked results and odds snapshots for this fixture — not from a generic stats feed.
We show the trend and whether it is already in the price. Most sites show the streak and let you assume you should bet it.
Recent form and head-to-head from our settled results — context behind the fair price. The price itself comes from the sharp market, not from these alone.

The full record is published daily to an external, append-only public log (Git history + OpenTimestamps), so it is independently verifiable — not even we can rewrite a past record undetectably. Verify on the public log →
External independent verification has been active since 20 June 2026. Earlier records are preserved in our internal ledger but were not externally timestamped before kick-off.
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.
