LineHound
Real-time screener, price-gap alerts, and your personal trading stats — across Kalshi and Polymarket. Know what moved, where the gaps are, and whether you're actually good.
Free during beta · Founding members lock $19/mo for life (later $29)
Prediction markets now trade $20B+ a month across multiple venues. Prices disagree, markets move overnight, and nobody can watch it all. That's the hound's job.
Every market on Kalshi and Polymarket in one sortable table — movers, volume spikes, spreads, and new listings the moment they drop.
When Kalshi and Polymarket disagree on the same event — or a price crosses your line — the hound barks. SMS, Telegram, or push.
Connect your Kalshi key (read-only) and see your real win rate, calibration curve, tilt patterns, and which categories actually make you money.
No deposits, no trading through us, no license needed on your end. We're the binoculars, not the casino.
Pick markets, price thresholds, and gap sizes you care about. Or let the hound suggest them from your trade history.
We poll both venues around the clock, match identical events, and compute gaps net of fees.
Alert hits your phone, you trade on Kalshi or Polymarket directly. The edge goes to whoever moves first — that's you now.
Flat subscription. We never touch your money and never take a cut of your trades.
No. LineHound is analytics software. You can't deposit, trade, or move money here. You trade on Kalshi or Polymarket directly — we just make sure you see what they don't show you.
Never. Personal stats use a read-only API key you generate in your Kalshi account. It can see your trade history; it cannot place trades or withdraw anything. Screener and alerts require no account connection at all.
Real but not magic. Gaps between venues exist daily; after fees and execution speed, the honest wins are modest and favor whoever sees them first. We show gaps net of fees so you're never chasing phantom edge.
We're onboarding the waitlist in small batches. Founding-member pricing ($19/mo for life) applies to everyone who joins the list before public launch.
