How Nimb works

Nimb is a living map of Polymarket prediction markets. It is built so retail traders read a market before they trade it: what the crowd expects, what moved, and who is behind the move.

What you see

How markets are chosen

Each event is scored at each timeframe, summed over its outcomes:

How undecided a price isI(p) = min(1, p(1−p) / 0.16)
Money on undecided outcomesA = Σ volume × I(p)
Scorelog₁₀ A + 0.3·log₁₀(1 + depth) + 5·min(move, 0.20) + 0.2·[resolves within 7 days]

A market must be open for trading; have at least $5k (24 hours), $30k (7 days) or $100k (30 days) traded on undecided outcomes; keep at least 10% of its volume on outcomes priced between 3% and 97%; and have a spread of at most 4 points or $10k of depth. The top 110 per timeframe are shown, with room for each category in proportion to its volume.

Where the data comes from

Questions

What is Nimb?

Nimb is a free, independent map of Polymarket prediction markets. Each circle is a market, sized by the money traded on it and coloured by category. Open one to see what traders expect, how it moved, who holds the largest positions, and to place an order from your own wallet.

Is Nimb part of Polymarket?

No. Nimb reads Polymarket’s public data and sends orders to Polymarket from the wallet you connect. Nimb never holds your money.

What does a price of 41% mean?

A share pays $1 if the outcome happens and $0 if it does not. If traders pay $0.41 for it, the market as a whole puts the chance at about 41%. It is the crowd’s estimate, not a forecast by Nimb.

How are the markets on the map chosen?

Every market is scored by how much money trades on outcomes that are still undecided, how deep its order book is, and how much it moved. A market must be open for trading, active enough, not already decided and cheap enough to trade. The top 110 per timeframe are shown, with room for each category in proportion to its volume.

How fresh is the data?

Prices stream live from Polymarket’s order book. Volumes refresh every minute. The list of markets refreshes every 5 minutes in the app and every 6 hours on these pages.

Why are some wallets left out of the holder lists?

A wallet holding both Yes and No in the same market has a position that cancels out. It is not a bet, so Nimb leaves it out of the leaning and the P&L.

Can I trade from Nimb everywhere?

No. Polymarket is not available in the United States, the United Kingdom, France and other restricted countries. Nimb checks Polymarket’s location check before every order.

Is this financial advice?

No. Nimb shows public data. Prediction markets are risky and you can lose your whole stake.
