First run guide

Check whether a Polymarket price is actually executable.

RealityGap is not a prediction engine. Use it to compare visible price with executable price, spread, orderbook depth, clean size and exit-side weakness before you trust the headline price.

Start here: load a market or use the available demo/live flow, then read the score as execution quality: not a forecast, not financial advice and not a recommendation.

What this checks

RealityGap reads public market and orderbook data to estimate execution friction for a selected entry size. It compares the visible price with the effective entry that current depth can support.

Why headline prices can mislead

A visible Polymarket price can look clean while the orderbook behind it is thin, wide, or uneven. The next executable entry can be meaningfully different from the headline price.

Visible price vs effective entry

RealityGap highlights the gap between the visible price and the effective entry price for the chosen size. This shows current execution quality, not whether an event will happen.

Spread and orderbook depth

The tool checks bid/ask spread and orderbook depth. Wider spreads and thinner books can make a displayed price less useful for a real entry size.

Clean size

Clean size estimates how much notional size the current orderbook can support before execution quality deteriorates beyond the clean-size threshold.

Exit-side liquidity

RealityGap also checks bid-side liquidity. Weak exit-side liquidity can make leaving harder than entering, even when the entry side looks usable.

Prediction market execution quality

The RealityGap score is about execution quality: spread, depth, effective entry, clean size and exit-side liquidity. It is not an event probability model.

How to read a RealityGap result

The checker is designed to answer one practical question: does the price you see resemble the price you can actually execute for your selected size?

Visible price vs executable price

Visible price is the market headline. Executable price estimates what your selected size can actually fill at after consuming available orderbook levels.

Spread and orderbook depth

Spread shows the gap between best bid and best ask. Depth shows whether enough size exists near the displayed price, or whether the book becomes fragile quickly.

Clean size

Clean size estimates how much can be entered before slippage becomes meaningfully worse. Small clean size can mean the headline price is only usable for tiny orders.

Exit Risk

Exit Risk flags when the bid side may be weaker than the ask side. A market can be easy to enter but hard to exit. Learn more.
