PREDICTION MARKET EXECUTION INTELLIGENCE
Anyone can find a spread. ArbCatch tells you if it's worth taking.
ArbCatch watches Kalshi, Polymarket, and Polymarket US around the clock. When the same event trades at two prices, we grade the gap before you put a dollar in it.
SEATS ARE CAPPED. NO SPAM, EVER.
KALSHI
POLYMARKET
POLYMARKET US
EVERY GRADE BACKED BY OUR OWN TRADING RECORD
YOUR KEYS NEVER LEAVE YOUR BROWSER. WE NEVER TOUCH FUNDS OR CREDENTIALS.
A raw spread is not a trade.
Scanners show you a number. They don't tell you that fees eat half of it, or that one leg has $200 of depth, or that the two markets settle by different rules. The spread is the easy part. Knowing which spreads are real is the whole game.
THE TERMINAL: OPPORTUNITIES, GRADES, POSITIONS, AND P&L IN ONE PLACE.

INSIDE THE TERMINAL
Built like a desk, not a feed.
SCANNER + WATCHER
Kalshi, Polymarket, and Polymarket US, watched around the clock. Open positions monitored, with an alert the moment a spread turns on you.
GRADING ENGINE
Every opportunity scored on profit after fees, volatility, and resolution mismatch before it reaches you.
ONE-CLICK EXECUTION
Connect your venue API keys and fire both legs from the terminal, sized to real book depth. Keys stay in your browser. They never touch our servers.
ALERTS
Arb and exit notifications in your Discord or Telegram, tied to your account alone. The full breakdown lives in the terminal.
FULL AUTO-EXECUTION IS IN CLOSED BETA WITH THE FOUNDING COHORT.
EVERY OPPORTUNITY, GRADED
One score. Three checks behind it.
Every opportunity in the terminal carries an Edge Score. One number you can act on, built from three checks you can inspect.
Profit after fees.
The number that survives contact with reality. We take the headline gap, subtract both venues' fees, and price it across the actual order book at your size. What's left is yours.
Volatility.
How often this market actually moves. Movement is what closes a spread, so this is your runway and your risk in one number, backed by the history of every spread we've tracked with the same profile.
Resolution mismatch.
Two markets can describe the same event and settle it differently. Different sources, different cutoffs, different definitions. Our models read both rulebooks and flag the traps before you're standing in one.
From entry to exit.
Most tools go quiet the moment you enter. ArbCatch keeps watching. It monitors your positions, alerts you when a spread turns against you, and logs every realized dollar in the terminal. The trade isn't done when you click. Neither are we.
INCLUDED, NOT UPSOLD
The terminal is the instrument. We teach you to play it.
Every seat includes the full curriculum: how cross-market arbs work, how to read a grade, how resolution risk bites, how to size a position. Then we get on a call and review your first trades with you, one on one. We cap seats partly because we onboard every user personally.
TRACK RECORD: A 14-DAY SNAPSHOT
We trade this engine ourselves.
The 30-day opportunity guarantee.
If ArbCatch doesn't surface at least 10 positive-edge opportunities in your first 30 days, we refund you in full. No forms, no fine print. We can make that offer because the terminal runs on the same engine we trade with ourselves. We know what it finds.
FOUNDING PRICING
Seats are quarterly. Here's why.
One month is too small a sample to judge an edge, so we don't sell one. Your first 30 days are covered by the guarantee.
FOUNDING PRICE, LOCKED FOR AS LONG AS YOU STAY. FUTURE COHORTS WILL PAY MORE.
SEATS
Twenty-five seats. That's the first cohort.
Every extra trader competes for the same spreads, and we onboard each user personally. So access opens in small cohorts, not floods. The Founding 25 lock their price for as long as they stay, get direct access to the team, and get first claim on every seat expansion after.
