What is this?
A live read on a single Polymarket contract. The market price is what traders are paying for a YES share. Wire’s read is what our archive says a contract priced like this should be worth, based on how similar ones have resolved.

How do I read it?
The Wire Signal is a 0–100 score. Traffic light: 0–35 = NO is the value side, 45–55 = we agree with the market, 65–100 = YES is the value side. Grade is confidence: A strongest, D noisiest.

How do I use it?
Strong zones with a Grade A or B are where Wire thinks there’s a real mispricing. Calibrated zones mean the market is already priced right. Not trading advice — never bet more than you can afford to lose.
