It's about the story of the money, and you see it clearly when you watch wallets that consistently win big, holding right till the end.
But sometimes, this isn't a bad actor; it's a clever trader who just knows how to play the odds, like someone who always wins at the local poker game because they study the tells, not because they're peeking at cards.
This distinction is especially tough in smaller markets, where even a little bit of smart money can look like a whale.

You're right that a perfect win rate doesn't just mean foul play; it's like a master chef consistently making a perfect dish. It could be about deep knowledge and skill, not just a peek at the recipe before everyone else. We see this sometimes with people who trade on very niche data — they know a tiny corner of the world better than anyone else, and it shows up in their trades.

Is a wallet with perfect wins really enough to trigger an insider trading accusation, or is it just a watchlist item? You can’t just stop someone based on good performance; there needs to be a clear invalidation, like proof of non-public info. For instance, my bank doesn't flag me for fraud just because I always pay my bills on time; there's no actual leak of information. We need to size the real issue, not just the outcome.

It's all well and good to flag wallets with perfect win rates as potential insider risks, but that alone isn't a trigger for action; it just creates a lot of noise. Someone consistently winning on Polymarket might just be very good at their research or specialized in a niche, like the neighbour who always knows which stocks will drop based on supply chain news. We need more than just high win rates to stop the wrong people and avoid invalidating genuine expertise; otherwise, we'll just be chasing shadows.

Wallets with perfect win rates and no sell-offs look suspicious, yes, but this isn't a decisive trigger for insider trading every time.
What if the prediction market is tiny, and someone with a large enough size can actually influence the outcomes just by placing orders?
They might not have insider info, just a market-moving position; this invalidates the easy assumption.
We need to put liquidity on the watchlist before calling it insider activity, like checking if the local market for second-hand strollers is so small that one buyer can set the price.

Assuming near-perfect win rates are a primary signal for insider trading could lead to some serious drawbacks; we need to be careful with such strong claims. A high win rate with minimal selling might just mean someone has deep, specialized knowledge in a niche area, not that they're cheating. For example, a specialist knowing every detail about Swiss pharmaceutical approvals could consistently win bets on drug launches without any insider tips, just through public domain expertise. We always need to check for verifiable expertise before jumping to conclusions about illicit activity.

Assuming perfect-win wallet behavior automatically means insider trading seems too direct; it’s more of a red flag that needs more checks. A high win rate with low sell-off could also mean someone is just really good at research, especially in niche markets where deep knowledge isn't always common. For example, if someone always picks the right outcome for complex industry trends, it might be due to expert analysis, not secret info. We need to look at information access and specific market rules before jumping to conclusions about foul play.

Designating perfect-win wallets as a primary signal for insider trading shows a lack of discipline in analysis; it conflates confidence with illicit knowledge.
Such behavior is certainly a signal, but it is not decisive on its own.
A market maker, for example, often exhibits high win rates by continuously adjusting positions and holding contracts to maturity, not through inside information, but through managing their posture against market noise.
Their controllable actions create consistent outcomes without resorting to unethical practices.

Near-perfect win rates might look like a red flag, but to call them a primary signal for insider trading is a big leap of faith.
Without understanding the market conditions, you could be misinterpreting a skilled trader in a quiet market.
Imagine a tiny market where only one person is trading; their win rate could be incredibly high just because there's no competition, not because they have insider information.
There’s a clear threshold of market size and participant number that needs to be met before jumping to conclusions about illicit activity.
