CrowdIntel3 sports wallets: 67% win rate across 174 resolved bets
3 Polymarket wallets, all funded from a single on-chain address, placed 174 resolved bets on sports markets and won 67% of them — a result you would expect about 0.45% of the time by chance. They moved $547K in volume for $57K in net profit.
The evidence
Across 174 resolved bets the cluster won 67% outright. Adjusting for sample size, the Bayesian win rate is 67% at 90% confidence, and the result sits 4.0 standard deviations above a 50/50 baseline. A coincidence of this size would occur about 0.45% of the time.
How the wallets are linked
These wallets share the funder 0xf504…e222, but that address behaves like shared infrastructure (an exchange, relayer, or the Polymarket proxy factory) rather than a single coordinator, so the "shared funding" link is NOT treated as evidence of coordination here.

Methodology & limitations
How we detect these clusters, what the numbers mean, and what we do not claim.
How we detect it
Every Polymarket trade is read directly from the Polygon blockchain. We trace the USDC that funded each trading wallet back to its source address. Wallets sharing a single funder are grouped, their funder is screened against exchange / relayer / proxy-factory infrastructure, and only genuinely coordinated funders are reported as clusters. Their market outcomes are then aggregated from on-chain resolutions.
What the numbers mean
- Win rate — resolved bets won ÷ total resolved.
- Bayesian win rate — win rate shrunk toward 50% to correct for small samples; closer to raw as the sample grows.
- Confidence — how much the sample size supports the estimate.
- Z-score — standard deviations above a coin-flip baseline.
- By chance (p-value) — how often a result this strong would happen by luck.
Funding linkage
A “verified” funding link means the wallets received USDC from the same address and that address is not a known exchange, relayer, or the Polymarket proxy factory. We currently trace direct (one-hop) funding; multi-hop and same-batch timing analysis are in progress.
What we do not claim
We do not assert the identity of any wallet owner, their intent, or that any law was broken. Shared funding plus an improbable win record is evidence worth examining — not a verdict. Figures are computed from on-chain data and update as markets resolve.
