A "fast cash out" mechanism that extracts an average of $111,000 per month has been discovered on Polymarket—someone has thoroughly understood this 15-minute price range trap.

Unlike ordinary gamblers who chase highs and cut losses, the logic of these professional arbitrageurs is very straightforward: they don't care at all where BTC or other cryptocurrencies are headed. What they want is to seize the time difference in the system's response.

How exactly does it work? At the moment the 15-minute settlement window opens, take advantage of the exchange's market push delay to lock in the price position in advance. While most retail investors are still watching the market refresh, arbitrageurs have already completed their bets and settlements. Although this time difference is short, it is enough to consistently extract considerable profits each month—an average of $111,000 per month comes from this.

The key is that this is not about making money by predicting prices, but by taking advantage of the information asymmetry in the market. Polymarket's new product design gives these savvy traders the opportunity to turn "systemic delays" into a "cash machine." While most people are still anxious about the direction, the top traders in the industry have already shifted their attention to the gaps in these micro-structural issues.
