Gaps you'd never find by hand
ArbLense keeps scanning matched markets across the three live venues. The board stays live instead of relying on a hardcoded claim.
Arbitrage scanner for prediction markets
Live routes to your Telegram - you take the difference, we take $0 of it.
When YES on one venue plus NO on another costs under $1, one side pays $1 at settlement. We scan Kalshi, Polymarket and Opinion every 10 seconds - 15 routes live right now.
Before fees and slippage - not a guarantee
What ArbLense does that you can't do by hand
Kalshi, Polymarket and Opinion in one feed
Three venues matched to each other. Opinion is the third one - most scanners stop at two.
Re-checked every 10 seconds
Prices move. A route that stopped working is marked, not left hanging.
Only routes you can actually buy
We read both order books and show room to trade - how many pairs exist at these prices. No theoretical spreads.
Routes come to you in Telegram
Free feed: 5 qualifying routes up to 3.0c, one message per route. PRO carries every qualifying route through the day.
Your money never touches ArbLense
No deposits, no wallet connect. You place both orders yourself on the venues.
