Pricing

One plan, billed how you prefer. There is no free tier: the scanner costs real money to run and a crippled free version would mostly teach people the product does not work.

What's included

Every pair the six-hourly scan matches across Kalshi, Polymarket US, Polymarket and Novig (up to 15,000 markets per venue)
Game lines matched on what they pay — same game, same side, same line — however each venue words them
Net edge after each venue’s own fee formula, not an assumed percentage
Order books walked to the size you actually want, not the top-of-book quote
A confidence grade on every pair, with the rule differences written out
Custom search: horizon, confidence, minimum edge, and how much capital fits
Price lookup — which venue pays more for a position you already want to take

What it does not do

It does not place trades, hold your money, or tell you what to trade. It does not promise that an opportunity will still be there when you get to it — order books move, and every number on screen carries the age of the book it came from. On plenty of days it finds nothing worth acting on, and says so rather than padding the list.

Coverage, returns and refunds

Each scan covers up to 15,000 markets per venue, so the list is not exhaustive: many markets on each venue are never compared. Hypothetical, not a projection of results: annualized figures assume both legs fill at the prices shown and resolve identically.

Payments are generally non-refundable, but if ArbScout is materially not working and we cannot fix it, we refund the current period. Cancelling stops future renewals. Read the Refund Policy.
