01The Core Thesis
Prediction markets can be inefficient. Some traders consistently outperform the market on sports. We surface them, you decide who to follow, and the tool tracks real performance from the moment you add them.
1. We cast a broad net
We continuously discover Polymarket wallets with notable sports betting activity — 200+ and growing. No pre-filtering, no curated shortlist. You see the full universe of candidates with their historical stats.
2. You choose who to follow
Browse wallet track records, ROI, sample sizes, and consistency. Add the ones you trust to your watchlist. Remove them anytime. You're in control of which insiders you track.
3. Get real-time signals
When a wallet you follow takes a new pre-game sports position, you see it immediately with the confidence score, bet sizing, and live market price.
4. Forward test automatically
Every wallet is timestamped when added. From that point, all new resolved positions are tracked as forward test results — real out-of-sample performance you can verify, not just historical stats.
02How We Evaluate Wallets
Anyone can get lucky over 10 bets. Over thousands of bets, luck averages out. We give you the stats to judge for yourself whether a wallet's track record is genuine, and the forward test to verify it going forward.
What you see
Every discovered wallet shows pregame ROI, sample size, consistency, win rate vs. implied probability, and sport-by-sport breakdowns. You can evaluate the full historical track record before deciding to follow.
On Polymarket, the price you pay is the implied probability. If you buy YES at 60c, the market thinks there's a 60% chance of YES. A wallet that consistently wins more than their entry prices predict is outperforming the market. We surface this data — comparing actual win rate against expected — so you can spot genuine edge, not just hot streaks.
The forward test
Historical stats tell you what did happen. The forward test tells you what happens next. When you add a wallet, we timestamp it. Every position resolved after that timestamp is tracked separately as a forward test result. This gives you a clean, out-of-sample record that the wallet can't retroactively inflate.
Why this matters
Past ROI alone doesn't prove edge. A hot streak can inflate returns. By separating historical performance from forward test results, you can independently verify whether a wallet's edge is real and ongoing — not just a backtest artifact.
03Confidence Scoring
Not all sharps are equal, and not all of their bets carry the same conviction. The confidence score captures both.
Wallet Quality
A composite of pregame ROI, sample size, consistency over the last 180 days, and pre-game market coverage. Better wallets produce higher scores.
Conviction
How much is the sharp risking relative to their normal bet? Measures true exposure (potential win), not just dollars wagered.
Slippage
How much has the price moved from the sharp's entry? Upward movement (edge eroding) penalizes the score. Price improvements boost it. Validated out-of-sample.
Why conviction matters
If a sharp's average bet is $1,000 and they drop $5,000 on a single market, that's a strong signal because they're sizing up. They have higher confidence in the outcome. A bet at or below their average tells you much less. We measure conviction as a multiple of the sharp's typical bet size.
04Forward Testing
Backtests tell you what would have happened. Forward testing tells you what actually happens. Every wallet you follow has its own forward test built in.
When you add a wallet to your watchlist, we record the exact timestamp. From that moment, every new position the wallet takes and every outcome that resolves is tracked as a forward test result, completely separate from historical stats. No cherry-picking, no hindsight filtering. You get a clean, verifiable record of how the wallet performs after you started watching.
Per wallet
Each wallet gets its own forward test from the moment you add it
Timestamped
Clear before/after boundary — historical stats vs. live results
Automatic
Every resolved position after the timestamp is tracked with no manual input
Why per-wallet forward testing matters
A wallet's historical ROI could reflect a hot streak that's already over. The forward test gives you an independent, out-of-sample track record that starts fresh when you do. If a wallet's forward test diverges from its historical stats, you'll see it and can remove them from your watchlist.
Forward test results depend on when you added each wallet and which positions resolved after that point. Your results will differ from other users who added the same wallet at a different time.
05Confidence Score Distribution
Here's how confidence scores are distributed across a typical batch of ~500 live signals.
Most signals land in the 60–79 range. Higher scores (80+) reflect strong wallets betting with conviction at favorable prices — these are the ones worth paying attention to first.
