Start with what the data covers
0xinsider stores the Polymarket trades it ingests, which is not every fill, wallet, or historical event. Provider availability, pagination limits, identity resolution, and ingestion timing all decide what you can review.
Before you read anything into a large trade, check the source, event time, wallet, market, side, price, and notional on the row itself. Missing context stays unknown. A market title, slug, or later outcome does not replace the provider's trade metadata.
Treat scores as diagnostics
A diagnostic score combines context such as trade size, wallet history, timing, liquidity, and unusual activity. It ranks trades for checking. It does not identify an insider, measure how sure a trader is, or estimate the chance that a position wins.
Read the fields behind a score and how they are computed, then decide whether they bear on the question you are researching.
A trade shows what happened, not why
A large fill proves that the provider reported a trade with that side and size. It does not show why the trader acted. The same trade can be a new view, a hedge, an exit from a position elsewhere, market making, or rebalancing.
A wallet's grade and profit history add context, but past results do not make the current trade right or copyable. Latency, liquidity, capital, fees, and a partial position history can make that trader's execution differ sharply from yours.
How to check a large trade, step by step
First, confirm the provider row and its timestamp. Next, check the market's state and liquidity near that time. Then review the wallet's stored history, and whether the sample is big enough for the metric you are using. Finally, compare independent public information and write down what is still unknown.
Use the large-trade feed and suspicious-trade flags to decide what to research, not to reach a conclusion for you. A good note separates provider facts, derived metrics, your own interpretation, and what is uncertain, so another reader can follow the reasoning.
Common questions
What does sharp money mean in a prediction market?
On 0xinsider, sharp money is the money that S, A, and B-graded wallets hold on each side of a market. Elsewhere it is informal language for money someone believes is informed. A large trade or a diagnostic flag alone cannot show that it is.
Does a high diagnostic score predict a winning trade?
No. The score organizes available context for review. It does not predict the outcome, certify private information, or replace independent analysis.
Does 0xinsider contain every Polymarket fill?
No, and we do not claim to. 0xinsider shows what it ingests and stores, which depends on source availability, pagination, identity resolution, and ingestion timing.
How should I investigate a large trade?
Verify the provider row, inspect market state and liquidity, review the wallet history that is available, compare independent information, and write down what is unknown instead of guessing intent.
