Overview

What the Arb Scanner is

The Arb Scanner helps users find potential arbitrage opportunities across prediction markets.

It is designed to compare related markets, identify price differences, and surface opportunities that may be worth reviewing.

Instead of manually checking multiple venues, markets, and outcomes, the Arb Scanner gives users a faster way to spot possible inefficiencies.

What the Arb Scanner is for

Use the Arb Scanner when you want to:

• find possible cross-market opportunities
• compare related contracts across venues
• detect price differences between similar outcomes
• review potential arbitrage setups
• monitor opportunities that may disappear quickly
• understand whether a spread is worth deeper attention

The Arb Scanner is built to reduce manual searching, not replace judgment.

How it works

The Arb Scanner looks for markets that may be related across supported venues.

When it finds a possible match, it compares the relevant prices and calculates whether there may be a spread between them.

A listed opportunity may include:

• the related markets
• the platforms or venues
• the relevant outcomes
• the visible price difference
• estimated spread
• supporting market details
• freshness or update timing
• status or confidence indicators

The goal is to help users quickly decide which opportunities deserve attention.

What counts as an opportunity

An opportunity may appear when two or more related markets have prices that are meaningfully different.

This does not always mean the trade is automatically good.

A spread may exist because of:

• true market inefficiency
• different liquidity conditions
• stale pricing
• different resolution rules
• fees
• market structure differences
• timing differences
• low fill probability
• mismatched contract language

The Arb Scanner is meant to surface candidates. Users should still review the market details before acting.

Why opportunities can disappear

Arbitrage opportunities can be temporary.

They may disappear because:

• prices update
• another trader captures the spread
• liquidity changes
• one side becomes unavailable
• the market closes
• the scanner refreshes with newer data
• the opportunity no longer meets the filter threshold

If an opportunity looks interesting, review it quickly.

Match quality

Not every market that looks similar is actually equivalent.

The Arb Scanner may compare markets based on names, outcomes, event structure, timing, and other matching logic.

Before acting, users should check:

• whether the markets resolve the same way
• whether the outcomes truly match
• whether the close dates are compatible
• whether fees change the trade
• whether both sides have enough liquidity
• whether one market has stale or thin pricing

A high spread with weak match quality can be worse than a smaller spread with cleaner structure.

Using the Arb Scanner

A typical workflow:

1. Open the Arb Scanner.
2. Review the current list of surfaced opportunities.
3. Sort or filter by spread, freshness, venue, or confidence if available.
4. Open the opportunity details.
5. Compare the market terms and outcomes.
6. Check liquidity and pricing.
7. Decide whether the setup is worth acting on, saving, or ignoring.

Best practices

Use the Arb Scanner as a starting point.

Before acting on an opportunity, check:

• market resolution rules
• price freshness
• liquidity on both sides
• fees and expected return
• whether the markets are truly equivalent
• whether the opportunity is still available
• whether execution risk is acceptable

A clean opportunity is not just the biggest spread. It is the spread with the best combination of match quality, liquidity, freshness, and execution feasibility.

Common issues

“The spread looks good, but the markets are not identical.”

Do not treat it as a clean arb until you confirm the resolution rules and outcome structure match.

Similar markets can still resolve differently.

“The opportunity disappeared.”

The market may have updated, the spread may have closed, or the opportunity may no longer meet scanner filters.

“The scanner shows fewer opportunities than expected.”

There may be fewer valid matches available, filters may be narrow, or current market conditions may not have many visible spreads.

“The opportunity looks stale.”

Refresh the scanner or check the source markets directly.

If the data still looks outdated, contact support with the opportunity and affected venue.

“The spread is large but seems suspicious.”

Large spreads can be caused by bad matches, stale data, low liquidity, or incompatible contract terms.

Review carefully before treating it as actionable.

Important note

The Arb Scanner is a research and discovery tool.

It does not guarantee profit, confirm execution, or determine whether a trade is suitable. It helps users find potential opportunities faster so they can apply their own review and judgment.
