Polymarket sweep alerts
What is a sweep?
On prediction markets like Polymarket, odds move as people trade each side of a bet. Most of the time that trading is unremarkable. A sweep is different: several trades push into one side fast — at least three trades in the same direction within about two minutes, together moving $10,000 or more. That's a real, fast move backed by real money.
What a sweep does not tell you is who made it. The same pattern looks identical whether it came from one large trader or from fifty small ones acting independently — Darkmen has no way to tell the difference, because it never looks at wallet identity when checking for a sweep, only at the market, the side, and the timing of trades. A sweep is not evidence that anyone had inside information; it's evidence that the market just moved.
What Darkmen tracks
The Polymarket Odds Sweep module watches every active Polymarket market and fires an alert the moment trading on one side moves fast enough to clear that bar. It captures:
- The market question — what event is being bet on
- How many trades fed the move, and their combined USD volume
- The latest trade price
- A direct link to the market so you can dig in immediately
The goal is to surface the moment a market reprices hard, giving you time to look at it yourself.
How the alert works
When a sweep meets the detection threshold, Darkmen sends an alert to all your enabled delivery channels within seconds. The alert itself is the whole signal — there's no added strength score or trading recommendation on top of it. Look at the trade count and total volume to judge how big the move was, then check the market link if you want more context.

FAQ
What is a Polymarket sweep?
A sweep fires when trading on one side of a market moves fast: several trades in the same direction within about two minutes, adding up to $10,000 or more. That tells you real money moved quickly. It doesn't tell you whether it was one large trade or many small ones, and it isn't evidence that anyone coordinated anything.
Why do sweeps matter for crypto traders?
A sweep means the market just repriced hard and fast on real volume, and you see it within seconds of it happening. That's useful on its own — you can look at the market and decide what to do. Darkmen doesn't tell you why the market moved or who moved it.
What size sweep should I pay attention to?
Every alert has already cleared Darkmen's bar for a sweep — there's no extra size filter to apply on top. The alert shows the trade count, the total volume, and the latest price, so you can judge the move yourself; bigger and faster is generally more interesting, but Darkmen doesn't grade sweeps beyond firing the alert.
Does Darkmen cross-check related markets?
No — the alert covers the one market where the sweep happened: the question, the trades behind it, the latest price, and a direct link. Checking other markets for a related move is on you.
