Methodology
tail.bet is a public record of the biggest real-money sports bets. This page explains exactly where the data comes from, how we capture and grade it, the standards we hold it to, and how our recap articles are produced.
Where the data comes from
Stake operates a public high-roller feed showing recent large bets across every sport. Our system captures each qualifying bet as it appears, takes a high-fidelity screenshot of the official bet slip, and records the outcome once the match settles. tail.bet runs in coordination with Stake — we are not scraping a private feed. Every figure on the site is derived from bets that actually appeared on that public feed.
What we capture, and the threshold
Each bet above a meaningful stake threshold gets its own page: the original bet-slip screenshot, the match, the market and selection, the odds, the stake, the user who placed it (when not anonymised), and the outcome. Aggregations then break the same data down by sport, league, team, tournament, and individual whale, and the leaderboard ranks the most active high-rollers by volume, bet count, and win rate.
How outcomes are graded
A bet is recorded as pending when captured and settled once the result is final on Stake's side — win, loss, cashed out, or void. The site rebuilds every few minutes from the live pipeline, so new bets appear within that window of being placed and outcomes update as matches settle. We report the outcome the feed reports; we do not adjust or interpret it.
Editorial standards
tail.bet records where the biggest money goes and what happens to it. No tips, no predictions, no edits after the fact. A captured bet is a public record that stands regardless of how it settles — in a market full of operators that quietly delete losing positions, a permanent log of what got placed, at what odds, on what match, is the whole point. We never remove a bet because it lost, and we never change a recorded outcome after settlement.
How these articles are produced
Our capture, screenshotting, grading, and the recap articles and video clips are produced by tail.bet's own software, working directly from the captured bet data. Every stat, figure, and ranking in a recap is pulled from the live archive described above — the articles summarise real recorded bets, not opinion or speculation. A human operator maintains the pipeline and oversees what publishes. We disclose this plainly because the value here is the underlying record, and that record is only as good as its transparency.
