FAQ
What exactly am I paying for?
Coverage and speed. ArbMonster continuously scans every major US sportsbook (25+) and both major prediction markets (Kalshi and Polymarket), walking live order books and running millions of price calculations a day to surface every cross-venue gap — net of every fee, at a size the books can actually fill. The free plan shows a small daily sample of what the engine finds; paid plans show all of it, the moment it appears, with alerts so you don't have to watch the dashboard.
Why are the plans so cheap?
Founding pricing while we grow. We know the math on the cards we show — a single well-sized gap can exceed a month of Core — and early subscribers lock the founding rate for as long as they stay subscribed. Prices rise as coverage grows; your rate doesn't.
Is there a guarantee?
7-day money-back window on every paid plan, honored without friction. Annual billing is 30% off. Cancel anytime from your order confirmation email.
How fresh is the data?
Prediction-market prices stream live on every plan. Sportsbook lines refresh every 15 minutes, pre-game only — a countdown on the dashboard shows the next refresh. Live in-game scanning arrives as we scale; Pro gets it first.
Does ArbMonster trade for me?
Never. ArbMonster is a data service — it measures public market prices and shows the math, net of fees, at a size the books can fill. It does not place trades, hold funds, or promise outcomes. See our Terms.
