Big Bets Gone Wrong as Polymarket Traders Burn Nearly $10M in a Month
Nearly $10 Million Lost on Polymarket as High-Stakes Traders Learn the Cost of Risky 50–50 Bets
Two high-profile traders on the blockchain-based prediction platform Polymarket have lost nearly $10 million combined in less than a month, highlighting the risks of aggressive betting strategies even in markets that appear evenly balanced.
On-chain analytics firm Lookonchain brought the losses to public attention, sparking widespread discussion across the crypto community about risk management, probability, and the dangers of high-volume wagering without a clear statistical edge.
At first glance, many of the bets appeared reasonable. The traders focused heavily on sports prediction markets where odds were close to 50–50, resembling coin-flip scenarios. However, the final outcome revealed how quickly capital can evaporate when probability, repetition, and scale work against a trader.

Who the Traders Were and How Much They Lost
According to blockchain data, one trader operating under wallet address 0x4924 was responsible for the largest loss. Over a period of 24 days, this wallet placed 346 individual predictions across multiple sports markets.
Despite the sheer volume of activity, the trader’s overall success rate stood at 46.24 percent, below the critical break-even threshold required to remain profitable in near-even odds markets. As a result, the wallet recorded losses of approximately $5.96 million.
The second trader, known as Bossoskil1, adopted an even more aggressive approach. Over just 11 days, this wallet executed 65 predictions, but achieved a lower win rate of 41.54 percent. That short burst of activity resulted in losses of roughly $4.04 million.
Combined, the two traders lost close to $10 million, all visible on-chain in real time.
Why Near 50–50 Bets Are More Dangerous Than They Appear
Many of the bets placed by both traders were executed at price ranges between 0.48 and 0.57, indicating markets where the perceived probability of winning was only slightly better or worse than a coin toss.
In theory, such bets may seem relatively safe. In practice, they are among the most unforgiving.
In prediction markets, profitability at near-even odds depends entirely on maintaining a win rate above 50 percent over time. Even a small deviation below that threshold leads to consistent losses. When large sums of money are involved, those losses compound rapidly.
Analysts point out that at these odds, there is little margin for error. A trader who wins 49 percent of the time may feel competitive, but mathematically, the strategy is unsustainable.
“This isn’t bad luck,” said one market observer. “It’s basic probability. If you don’t have an edge, the market will eventually take everything.”
The Compounding Risk of Repetition
One of the most critical factors in the losses was repetition.
Placing hundreds of bets in a short time frame dramatically increases exposure to variance. Even if a trader experiences short-term success, repeated wagers without a statistical advantage almost guarantee long-term losses.
The situation has been compared to repeatedly flipping a coin while steadily increasing bet size. While a few wins may occur early, probability eventually reasserts itself.
In the case of wallet 0x4924, the sheer number of predictions amplified the damage. Each individual bet may have seemed manageable, but together they created a steady drain on capital that no recovery streak could offset.
Experts emphasize that repetition without discipline is one of the most common pitfalls in prediction markets.
Transparency Makes the Losses Impossible to Hide
Unlike traditional betting platforms, Polymarket operates entirely on blockchain infrastructure. Every trade, position, and loss is publicly visible.
This transparency is one of the platform’s defining features. It allows analysts and observers to study real trading behavior rather than relying on self-reported results.
In this case, the public nature of the losses turned them into a cautionary example. Lookonchain highlighted the wallets specifically to demonstrate how flawed strategies play out when exposed to market realities.
The visibility also removes any illusion that confidence or conviction can override mathematics.
Strategy, Not Luck, Determines Outcomes
Market analysts stress that the losses were not the result of sudden market shocks or unpredictable events. Instead, they stemmed from a strategy that relied on volume and confidence rather than measurable advantage.
Prediction markets may look simple, especially when outcomes appear evenly split. But they are designed to punish inefficiency. Without careful position sizing, selective participation, and clear probability assessment, losses accumulate quickly.
Risk management, experts say, is more important than prediction accuracy. Even skilled forecasters can lose money if they overbet or fail to control exposure.
Broader Lessons for Crypto and Prediction Markets
The incident has reignited debate about the growing popularity of prediction markets within the crypto ecosystem. Platforms like Polymarket have expanded rapidly, offering users the ability to speculate on sports, politics, economics, and global events.
Supporters argue that these markets aggregate information efficiently. Critics warn that they can encourage gambling behavior disguised as forecasting.
What this case demonstrates is that transparency alone does not protect traders from poor decisions. The tools may be advanced, but the underlying math remains unforgiving.
A Reminder as Prediction Markets Grow
As prediction markets continue to attract higher volumes and larger participants, stories like this are likely to become more common.
The losses suffered by these two traders serve as a reminder that even sophisticated platforms cannot compensate for weak strategy. High stakes amplify mistakes, and near-even odds leave no room for complacency.
For the broader crypto community, the lesson is clear. Prediction markets reward patience, selectivity, and discipline. They punish overconfidence, repetition, and the belief that luck will hold indefinitely.
In the end, the blockchain does not lie. And probability always collects its due.
