Polymarket coordinated betting & sweep alerts

What is a coordinated sweep?

On prediction markets like Polymarket, odds reflect the aggregate belief of the crowd. Most of the time they drift slowly. A sweep is different: odds jump several percentage points in minutes, driven by a sudden surge in volume. That spike means a lot of money entered one side at once — either a single large actor or a coordinated group of bettors all moving in the same direction.

Coordinated or sweep betting is significant because prediction markets are information markets. When sophisticated participants pile into one outcome fast, they are usually acting on information the broader crowd does not yet have. The odds movement is the signal; the news that validates it often arrives hours later.

What Darkmen tracks

The Polymarket Odds Sweep module watches every active Polymarket market and fires an alert the moment odds shift fast on rising volume. It captures:

  • The market question — what event is being bet on
  • Odds before and after the sweep, and the size of the shift
  • How large the volume spike was (in USD and as a percentage of the market's total)
  • A direct link to the market so you can dig in immediately

The goal is to surface the moment the crowd's conviction changes, giving you time to act before the move finishes.

How the alert works

When a sweep meets the detection threshold, Darkmen sends an alert to all your enabled delivery channels within seconds. The signal includes enough context to make a decision quickly.

What to do with it: Look at the size first. A shift greater than 10 percentage points on $1M+ volume is a strong signal worth acting on. Cross-check related crypto markets — prediction market sweeps and spot price moves often correlate. Avoid fighting a sweep that is already backed by $5M+ in volume; at that point the move is underway.

FAQ

What is a Polymarket sweep?

A sweep is when odds shift several percentage points in a short window, backed by a large volume spike. It signals that a significant amount of money moved into one side at once — coordinated or conviction-driven betting.

Why do sweeps matter for crypto traders?

Prediction market sweeps often happen hours before mainstream news picks up. The shift in crowd conviction is a leading indicator — you can ride the move or fade it before the broader market reacts.

What size sweep should I pay attention to?

A shift greater than 10 percentage points on a market with $1M+ volume is a strong signal. Below that threshold, treat it as noise. Never fight a sweep on $5M+ volume.

Does Darkmen cross-check related markets?

The alert includes the market question, odds before and after, volume spike size, and a direct link. You should then cross-check related crypto markets — they often move together after a sweep.

Which plan gives access to sweep alerts?

The Polymarket coordinated-sweep signal is available on the Pro tier. See the [pricing page](/en/pricing) for details.
