Professional-grade automated trading for Kalshi and Polymarket sports markets.
Quant4 Sports measures every Kalshi and Polymarket price against a margin-free consensus of the major sportsbooks, then posts limit orders when either one trades below fair value. It runs on your Windows or Mac PC, with your own accounts.
Membership is capped to protect fill quality. Early-access members are offered seats first.

A short tour of the Control Center: account view, results by sport, scanner controls, open bets and money safety. Account balances shown are sample figures.
Fair value first. Then patience.
Most Kalshi and Polymarket sports traders accept whatever price is showing. Quant4 Sports works the other side of the book: it posts bids below fair value and waits to be filled.
Fair value
Live odds from Pinnacle, DraftKings, FanDuel, BetMGM, Caesars and other books are combined, and the bookmaker margin is removed to estimate each outcome's true probability.
Compare
Every Kalshi and Polymarket market in scope is checked against that fair value, after exchange fees, many times a minute.
Post limit orders
When the edge clears the threshold, a resting limit order joins the queue at a price below fair value, paying the exchange's lower maker fee.
Stay inside limits
Bet size, daily budget and daily loss cap are set per sport. A depth cap scales orders down in thin markets, and an account-level fail-safe stops new orders.
Twelve sports. Winners, spreads, totals and halves.
One scanner per sport, all with the same structure and controls. Each sport can be switched on or off independently.

Game winners
Moneyline-style winner markets for every covered sport.
Spread and total ladders
Every rung of the Kalshi and Polymarket point-spread and total ladders is valued separately, spreading orders across many markets per game.
First-half lines
First-half spreads and totals for NFL, college football and the top soccer leagues.
Soccer covers the major European leagues, MLS, Liga MX, Brazil and other mid-sized leagues. Coverage follows what Kalshi and Polymarket list and what the odds feed prices.
Everything runs locally. Everything is measured.
Keys stay on the machine
Kalshi, Polymarket and data-feed keys are stored only on your computer. Quant4 Sports never holds funds, and trading keys cannot withdraw money.
Control Center
One dashboard to start and stop scanners, set bet size, budget and loss cap per sport, and watch open orders, fills and cash.
Proof, not promises
Per-sport profit and loss tables, plus a beat-the-close report that shows whether fills are actually better than the final pre-game price.
Depth-aware sizing
Orders are capped to a share of the line already waiting at that price, so a full bet goes in where the market can take it and a smaller one where it cannot.
Hands-off operation
Scanners start with the Control Center, restart after a reboot and run in the background. Optional phone alerts if a scanner stops.
Kalshi and Polymarket, side by side
The same games are priced on both exchanges, and each order can go to whichever one offers the better deal after fees.
Not for everyone, by design.
Quant4 Sports is a professional tool with a short setup. These are the requirements before subscribing.
Required

- The Odds API subscription, billed separately by The Odds API. The 5-million-credit plan (currently $119/month) is recommended for full coverage.
- Windows 10 or 11, or macOS 12 or later.
- A computer left on and connected during game windows.
- A trading bankroll of $3,000 or more is recommended so the edge can cover the data and subscription costs.
Not a fit for
- Anyone looking for picks, tips or guaranteed winners.
- Small accounts where monthly costs would exceed any realistic edge.
- Anyone unwilling to let the math run without overriding individual trades.
- Traders who need it to run on a phone or tablet.

Common questions
Does Quant4 Sports guarantee a profit?
No. It is software that applies a pricing method automatically. Results depend on markets, fills and settings, and losses are possible. Only trade money that can be lost.
Does Quant4 Sports trade on my behalf or hold any money?
No. The software runs on your own computer and connects to your own Kalshi and Polymarket accounts with your own keys. No funds pass through Quant4 Sports, and trading keys cannot withdraw money.
Why is The Odds API required, and why is it separate?
Fair value comes from live sportsbook odds, which The Odds API supplies. Each member needs their own account under The Odds API's terms, so it is billed directly by them.
Why is membership limited?
Every member's software looks for the same pricing gaps. In thinner markets, too many orders at the same price would crowd each other out. Seats are capped, and the cap is reviewed against real fill data as membership grows.
How big should a bankroll be?
$3,000 or more is recommended. The edge per contract is small, so it needs enough money working to outweigh the monthly data and subscription costs.
Windows or Mac?
Both. One license covers either. Python and everything else needed is bundled in the download, so nothing else has to be installed.
Will Windows or macOS show a warning when installing?
The first time the app is opened, Windows may show "Windows protected your PC" (choose More info, then Run anyway) and macOS may say the developer cannot be verified (open System Settings, Privacy & Security, then Open Anyway). This happens once. Step-by-step instructions are included with the download.
What data does the software send back?
A license check, plus optional anonymous summary statistics (such as fill rate and beat-the-close by sport) used to manage capacity. Keys, balances and individual trades are never sent.
When will it be available?
Early-access members are notified first when seats open, in the order they signed up.
