Three crypto wallets collectively walked away with roughly $24.25 million in profit on WorldCup-themed prediction markets, and on-chain analytics suggest a single operator may be behind all of them.
Wallet mintblade booked $9.24 million on five straight winning bets. GRIMDRIP turned two positions into $7.6 million. endlessFate closed six of nine for $7.41 million. All three wallets routed their profits through the same Binance deposit address (0xB08B...317D), a pattern consistent with a single controller splitting capital across identities to mask position size.
Why it matters
A win rate that high on a single event category is the kind of footprint that does not show up in legitimate retail flow. Prediction-market venues already police obvious single-account abuse, so the operator appears to be running multi-wallet camouflage rather than a single misconfigured bot. The Binance deposit address is the connective tissue: it is the one piece of infrastructure every wallet had to touch, and it is now visible to anyone watching the chain.
Market impact
The three wallets stopped trading and withdrew all funds after cashing out, which removes the immediate risk of follow-on positions. What lingers is the precedent for prediction-market integrity: if a $24M edge on a globally-watched event can be extracted in a single day, the venues underwriting these markets will face sharper questions about which side of the order book that flow is really coming from.
Frequently asked questions
-
How much did the suspected insider make on WorldCup prediction markets?
Roughly $24.25 million in profit, split across three wallets: mintblade $9.24M (5/5 wins), GRIMDRIP $7.6M (2/2 wins), and endlessFate $7.41M (6/9 wins).
-
What on-chain evidence ties the three wallets to one operator?
All three wallets routed their profits to the same Binance deposit address, 0xB08B...317D, before stopping trading and withdrawing funds. A single shared deposit address is hard to explain across three genuinely independent traders.
-
Why would an insider use multiple wallets instead of one?
Prediction-market venues enforce single-account limits and flag obvious abuse. Splitting capital across identities lets a single operator take larger total position size without tripping those venue-side controls.
-
Which prediction-market venue hosted these bets?
The seed does not name the venue. The on-chain footprint is visible in the wallet flow to Binance, but the underlying platform is not identified in the source material.
-
Are the suspected insider's funds still on-chain?
No. All three wallets stopped trading and withdrew funds after cashing out, so the immediate capital is no longer sitting in the prediction-market venues exposed to this incident.
