Prediction Market Analytics & Dashboards

What this category is, and what it is not

Nothing in this category runs a market. Every number on these pages is read off somebody else's venue: Polymarket's on-chain record on Polygon and its public APIs, Kalshi's market-data API, and the trade history each venue exposes. That single fact decides most of what follows. The product you are choosing is not a data source — it is an opinion about how often to poll one, how to normalise it, and what to compute on top.

So the first question about any tool here is not what it shows but what it reads and how often. A terminal that subscribes to a one-second WebSocket and refreshes underlying quotes every thirty seconds is a different instrument from an indexer that rebuilds positions in batches, even when both print a number in the same box. Ask which venues, which endpoints, and what the refresh interval is; if the tool does not say, that is an answer too.

This is the fastest-rotting section of the catalogue

Most of the products listed below carry a terms-of-service page written or last revised in 2026, and several of those dates are from the last few months. That is not a swipe at any of them; it is the shape of the market. Products at this age change their feature set, their price and sometimes their owner between one visit and the next; one of them labels itself a private alpha on its own home page, and another kept serving a static site for eight months after the commit that paused the pipeline behind it.

Two practical consequences. First, dates on this site matter more here than anywhere else: every card carries the day its pricing and availability were last checked against the vendor's own pages, and a claim more than a few months old should be re-read rather than trusted. Second, a tool in this category is a poor thing to build a workflow on without an exit — prefer the ones that expose a documented API you could re-point, and keep your own copy of anything you would miss.

A leaderboard ranks wallets, not traders

This is the single most misread thing in the category, and it is worth being blunt about.

Polymarket settles on a public chain, so every position and every fill is visible by address. That is what makes wallet analytics possible at all, and it is genuinely useful. What it does not give you is a person. One trader can run several addresses — deliberately, to split size or to keep strategies apart — and each will appear as its own row with its own record. One address can serve several people: a fund, a shared account, a Telegram bot trading for its users, or a market maker quoting both sides. A rank built on realised profit will also flatter an account that closes winners and holds losers, and an ROI column computed against a near-zero volume denominator will put a rounding error at the top of the table.

None of this makes the data wrong. It makes the label wrong. Read a leaderboard row as "this account has this record on this venue over this window", and check the window, because twenty-four hours, thirty days and all-time produce three different top tens from the same data.

The three numbers vendors use interchangeably

Volume is notional traded over a window. Liquidity is what is resting on the book right now, usually within a stated band of the mid. Open interest is capital currently at risk in unresolved positions. They answer three different questions — how much changed hands, how much you could move without walking the price, and how much conviction is still outstanding — and a market can be high on one and low on the others. A market with large all-time volume and a thin book is the most common trap: the history says liquid, the order book says otherwise, and the number you needed was the second one.

Two more that get printed as if they were obvious. Realised versus unrealised P&L is the difference between money taken off the table and a mark on an open position that may still resolve to zero. And a win rate counts resolved positions without weighting them, so an account can be right nine times out of ten and still be down.

What none of them can see

A dashboard reads one venue's public record, which bounds what it can honestly claim. It cannot see a hedge held on an exchange it does not index, an off-venue position, or the relationship between two addresses that belong to the same desk. On venues that are not on a public chain, wallet-level analytics do not exist at all — Kalshi shows aggregate market data and no per-account positions, which is why cross-venue tools here are thorough on Polymarket and thin on everything else.

And a dashboard cannot see whether a market will resolve the way its price implies. A price is what the crowd will currently pay, not a measurement of the world. Nothing in this category changes that, and the tools that compute a "fair value" or a "mispricing" are producing a model's opinion, clearly labelled as such on their own pages and labelled as such on ours.

Read before you pick one

Four things decide the choice more than the feature list does.

Who publishes it. A domain that contains a venue's name usually does not belong to that venue. The terms page names the operator; read it.

Which venues, and how deep. Polymarket-only is the default here. Cross-venue coverage is usually cross-venue market data plus Polymarket-only wallet analytics, because that is what the public record allows.

Whether it can also trade. Some of these are read-only. Others will place orders on your behalf once you hand over an exchange credential or link a wallet, and one of the features on offer is mirroring another address automatically. That is a different risk profile and a different set of questions — where the credential is stored, what the size caps are, and what happens when the copied account does something you would not have done.

What it costs, and what the free tier actually includes. Free browsing with paid API access is the common shape, and the open-source entries cost nothing at any tier. Some of the products here publish no price list at all, and at least one publishes a price list with no free plan behind it.
