What is a sweep?
A sweep (also called a high-conviction sweep) is what Edgewatch calls it when two or more independent tracked wallets all take the same side of the same Polymarket market within a short time window — typically a few hours.
Why sweeps stand out
On any given day, tracked wallets trade hundreds of markets. Most of those entries are independent calls — one trader is bullish, another is neutral, a third is bearish. When multiple independent high-conviction traders all pile into the same outcome at roughly the same time, it suggests they've arrived at the same conclusion from different starting points. That kind of agreement is rarer and statistically more interesting than any single trade.
The key word is independent. If the wallets share a funding source or historically move together, Edgewatch's Sybil heuristic flags and filters them. A sweep that survives that filter represents genuine convergence.
How Edgewatch collapses them
Without collapsing, a busy market could generate a noisy stream of five separate signal rows from five different wallets. Instead, Edgewatch merges these into one sweep signal that lists all contributing traders, shows the combined size, and surfaces the consensus direction. You see agreement, not noise.
What a sweep is not
A sweep is not a guaranteed outcome. Smart-money consensus can still be wrong — markets are uncertain by design. It is also not a buy recommendation. Edgewatchsurfaces the observable fact that multiple tracked wallets agreed; what you do with that information is your decision.
