New Wallets Show Hundreds of Resolved Wins Without a Recorded Loss
A Polymarket monitoring service has flagged 20 wallets for unusually strong trading records, including newly created accounts showing hundreds of resolved winning positions without a recorded loss.
GhostBetter, a service designed to identify statistical patterns associated with potentially informed prediction-market trading, said its Sept. 7-13 scan detected 20 suspicious wallets after reviewing more than 130,000 accounts.
Among the most extreme examples was a wallet that GhostBetter said was only four hours old but had accumulated a 173-for-173 resolved record while trading across 576 markets. The service said the wallet placed individual bets of up to $14,573.
Another wallet, created about 15 hours earlier, was listed with 268 wins from 268 resolved positions after activity spanning 1,181 markets. A third account showed a 526-for-526 record in the earlier weekly snapshot.
GhostBetter’s live dashboard had rolled forward to Sept. 8-14 by Monday and continued to show 20 active signals. The updated list included wallets with records of 173-for-173, 268-for-268, 213-for-213 and 322-for-322, among others.
The figures are unusual, but they do not establish insider trading.
GhostBetter explicitly describes its system as pattern detection rather than legal proof. Its current highest-ranked wallets receive a score of 66 out of 99, categorized as “Highly Suspicious,” rather than being classified as confirmed insiders.
The service says it scores accounts using three broad signals: whether a wallet appears to be a newly created “ghost” account, whether it has an unusually strong or perfect record, and whether large positions are taken shortly before an event becomes known.
That approach is increasingly relevant because market manipulation and insider trading have become one of the central regulatory questions surrounding prediction markets.
But headline win rates require careful interpretation.
A trader buying a contract for 99 cents after an outcome is effectively known could collect a technically perfect record while earning only a small return and taking very little genuine forecasting risk. Traders can also enter contracts shortly before formal resolution, exploit temporary pricing discrepancies or use systematic strategies targeting markets where the likely outcome is already extremely clear.
Polymarket’s structure makes those distinctions particularly important. Winning outcome tokens become redeemable for $1 after a market resolves, while losing tokens become worthless. A trader purchasing an almost-certain winner for 98 or 99 cents can therefore generate a win without having predicted the event when uncertainty was high.
That means investigators would need entry prices, timestamps, position sizes and the state of each underlying event before treating a perfect record as evidence of privileged information.
Wallet age is potentially more useful when combined with those factors.
Dave Finances previously identified Polymarket wallets placing millions of dollars against passage of the Clarity Act, including recently funded accounts whose timing and funding patterns attracted attention ahead of a major Senate vote. Those patterns were notable but did not by themselves establish common ownership or inside information.
The legal backdrop has become considerably more serious during 2026.
In April, U.S. prosecutors charged an Army soldier with allegedly using classified information about a military operation in Venezuela to make more than $400,000 through Polymarket contracts. The Justice Department said the defendant had participated in planning the operation and used nonpublic information to place approximately $33,000 in bets before the event.
Polymarket says it cooperated with authorities and now publicly states that trading on stolen confidential information is prohibited. Its market-integrity policy also prohibits manipulation, wash trading, self-dealing, front-running and other deceptive conduct.
Prediction-market enforcement has expanded beyond Polymarket. The CFTC has pursued cases involving other event-contract traders, including a case in which a Trump teleprompter operator was ordered to pay $172,539 over Kalshi trades.
Kalshi has also conducted its own suspicious trading investigations, including enforcement involving an editor associated with the MrBeast media operation.
The scrutiny is arriving as prediction markets move rapidly into mainstream finance. Polymarket and Kalshi have expanded distribution, valuations and institutional partnerships, while Polymarket has expanded its Sportradar relationship to include data and integrity services covering more than 20 sports leagues and competitions.
That growth makes tools such as GhostBetter potentially useful as lead-generation systems. But identifying a statistical anomaly is only the beginning of an investigation.
A Perfect Record Means Almost Nothing Without Entry Prices
The 173-for-173 number is irresistible.
So is 268-for-268. And 526-for-526 sounds almost absurd.
But this is exactly where prediction-market investigations can go wrong.
A perfect win rate looks devastating until you know what the trader actually paid.
If someone repeatedly buys contracts at 99 cents after the decisive information is already public, winning 500 consecutive markets is not remotely equivalent to correctly predicting 500 uncertain events at 50-50 odds.
The wallet still looks extraordinary on a leaderboard. Economically, however, the strategy may resemble collecting pennies in front of very small remaining resolution risks.
That is why GhostBetter’s alerts should be treated as a starting list rather than a verdict.
The most valuable next step is to rebuild every flagged wallet market by market.
For each position, investigators need to know when the wallet entered, what the contract was priced at, what information was publicly available at that moment, how rapidly the price moved afterward and whether the trader repeatedly appeared just before information shocks.
That is where blockchain-based prediction markets have one genuine advantage for surveillance.
The activity is visible.
Traditional insider-trading investigations often begin with regulators demanding brokerage records. With on-chain markets, independent researchers can identify unusual wallet behavior before knowing who controls the wallet.
That transparency has already turned prediction markets into an unusually fertile environment for amateur and professional forensic analysis.
But transparency has a limitation: an address is not a person.
You can see a fresh wallet receive funds, place an extremely well-timed bet and withdraw the proceeds. You cannot automatically tell whether its owner is a government employee, corporate executive, professional trader, market maker or someone who simply did exceptional research.
That identity gap is where exchanges, centralized crypto platforms and regulators become important. Following funds back to a service with customer identification records can sometimes turn a statistical lead into an actual investigation.
The danger is moving too quickly in the opposite direction.
Prediction markets are already under pressure over questions about market integrity and CFTC oversight. Labeling every high-performing wallet an insider would weaken rather than strengthen the evidence when genuinely suspicious cases appear.
The better filter is not simply win rate.
Look for fresh wallets taking concentrated positions while an outcome is still genuinely uncertain. Look for trades immediately before nonpublic announcements. Look for clusters of accounts funded from related sources. Look for repeated success in markets connected to the same employer, government agency, sports organization or corporate information channel.
And most importantly, look at price.
A wallet buying “Yes” at 99 cents and eventually receiving $1 is a winner.
A wallet buying “Yes” at 20 cents minutes before a surprise announcement is something else entirely.
GhostBetter’s 20-wallet list is therefore valuable precisely because it narrows a huge dataset into a manageable pool of leads. The records are extreme enough to justify investigation, but the numbers alone do not tell us why the wallets won.
The real stories will emerge only when those 20 records are reconstructed trade by trade.
