How it works

Math finds the gap. You collect it.

Prediction markets and sportsbooks price the same future twice. When those prices drift apart, the gap is yours to take — no prediction required.

01 — SCAN

Every market, every second

FindArbs pulls 450,000+ live markets from prediction markets like Polymarket and Kalshi, with sportsbooks on the way — politics, sports, crypto, economics, weather.

02 — MATCH

Same event, verified

Titles are paired across platforms, then AI audits reject the lookalikes — wrong year, wrong threshold, wrong topic. Survivors get a confidence score you can see.

03 — LOCK

Buy both sides under $1

Buy YES where it's cheap, NO where it's cheap. If the pair costs 97¢, you collect $1.00 at resolution — either outcome, the spread is yours.

Built for execution, not screenshots

A spread is only real if you can fill it.

Confidence tiers, not blind lists

Every pair is scored. Strong matches surface on the main grid, weaker ones wait behind a warning, and pairs that failed the harder guards get buried in the trash pile — visible if you want to dig, never mixed in with the real opportunities.

96% MATCH Fed July rate cut +2.88%
88% MATCH May CPI above 3.0% +1.94%
58% MATCH Hurricane US landfall by Aug verify first
REJECTED "S&P above 5000" vs "above 6500" threshold mismatch

Real orderbook depth

A 3% spread on a market with five contracts of liquidity isn't an arb, it's a mirage. FindArbs shows the live orderbook on both sides and suggests the trade size that actually fills at your target profit.

Sounds too good to be true?

Fair. Here are the honest answers.

What's the catch?

Three real ones: fees eat into thin spreads (check each platform's fee schedule), fills aren't guaranteed — prices move and orderbooks run dry — and mismatches happen, which is why every pair shows a confidence score and we tell you to read both event pages before betting. The spreads are real, but they're measured in single-digit percentages, not jackpots.

Is this still gambling?

A true arb is hedged — you hold YES and NO on the same event, so the outcome doesn't matter. The risk isn't which way the event goes; it's execution: partial fills, price movement between your two orders, and the rare mismatched pair. Treat it as a market-structure trade, and never bet on a pair you haven't verified yourself.

How big are the spreads?

Most live opportunities sit between +1% and +4%. Bigger numbers show up, but usually on lower-confidence pairs or thin orderbooks — that's exactly what the tiers and the depth view are for. Remember capital is locked until resolution, though both platforms pay roughly 4% APY while you wait.

What do I need to start?

Funded accounts on both sides of the trade — Polymarket and Kalshi today, with other prediction markets and sportsbooks coming (an arb always needs both legs) — and the scanner. Start small, verify every pair by clicking through to both event pages, and only size up once you've seen a few resolutions pay out.

Still skeptical? Fair. The community says it better:
