TransferGrapevine
Not rumors — sourced facts and explainable probabilities.
What makes it different
We convert transfer reporting into structured facts — Claims: who reported what, when, and where. We never republish articles; every fact links to its original source.
Probabilities you can audit
Every probability is computed by a deterministic formula from claim types, track-record-based source weighting and time decay — no AI vibes, no editorial gut feeling. Individual outlet and journalist ratings are internal weights only, never published.
Coverage
We track 28 leagues and 22,000+ players worldwide, centred on the Big-5 European leagues. Base data comes from Wikidata (CC0); photos are exclusively free-licensed Wikimedia Commons images.
