ArbiTrack: what it does, what it costs, where it stops
Last checked 2026-09-08
ArbiTrack is a scanner that matches events across Polymarket, Kalshi and PredictIt and lists price gaps, refreshing every 3 minutes. Its homepage says typical mispricings run 5 to 20 cents.
It is priced for occasional use. A 24-hour pass costs $4 and a month costs $19, paid in stablecoins on Polygon, with a free tier that shows 5 markets and hides the edge sizes.
What it does
The scanner matches the same event under different names on each venue and color-codes the gap: yellow at 8 cents or more, orange at 5 to 8 cents, green at 3 to 5 cents. You can filter by politics, economics, crypto, sports and climate.
The homepage shows $2.3B+ daily volume tracked and describes Polymarket at $3.7B+ monthly volume, Kalshi as CFTC regulated and PredictIt as political markets.
- Auto-refresh every 3 minutes
- Edge tiers: yellow 8 cents or more, orange 5 to 8, green 3 to 5
- Category filters: politics, economics, crypto, sports, climate
- Paid tiers described as hundreds more markets than the free view
Pricing
Free: $0, 5 markets, edges locked. 24-hour pass: $4. Weekly: $9. Monthly: $19. Annual: $149, which the site works out to $12.40 per month.
Payment is in USDC or USDT on Polygon, with a stated transaction fee under $0.01. There is no card checkout on the pages checked.
Venues and data
Three venues: Polymarket, Kalshi and PredictIt. The site does not publish how many markets it matches in total beyond the 5-market free view and the hundreds more in paid tiers.
A 3-minute refresh is slow relative to how fast books move on a live event. The gap you see may be gone by the time both legs are placed.
Where it falls short
The free tier is a preview: 5 markets and the edge column is locked, so you cannot judge signal quality without paying at least $4.
The site states it is an information tool only, does not execute trades and is not a financial advisor. Acting on a flagged gap means placing each leg on its venue, or using a cross-venue terminal.
Whether the displayed gaps are net of Kalshi and PredictIt fees is not stated on the homepage.
Who should use it
Traders who want a low-commitment scanner to check a few times a day. The $4 day pass is the cheapest way in the category to see live gaps across three venues.
