/// What it does >>>

The board, the edges, and the close.

The board

Every market Fairline tracks, one row each: a column per venue, and the best available price marked. No tab-switching, no hunting.

  • One row per market
  • One column per venue

Edge feeds

Fair value, +EV and arbitrage, with each venue’s fees priced in before anything reaches the feed. An edge thinner than the fee was never an edge.

  • Fair value
  • +EV
  • Arbitrage

Picks

Log what you took and at what price, then watch it against the close. Positive CLV is the best long-run signal that a process has edge.

/// Good to know >>>

Frequently asked questions.

Is Fairline a sportsbook?

No. Fairline is a research tool: it takes no wagers, holds no funds and settles nothing. You place your own bets, at your own venues, in your own name. 21+.

Where do the prices come from?

Kalshi and Polymarket for prediction-exchange markets, The Odds API for sportsbook prices, and MLB StatsAPI and ESPN for schedules, game state and player data.

Why do fees change the answer?

Because an edge thinner than the fee is not an edge. Fairline prices each venue’s fees into fair value, +EV and arbitrage before anything reaches a feed, so what you see is what would be left after the venue takes its cut.

What does “beat the close” mean?

It compares the price you took against where the market closed. Consistently positive closing-line value is the strongest long-run evidence that a process has edge — stronger than the result of any one bet.

Can I use it today?

Not yet. Fairline is in development for iOS and the web, and there is no App Store listing to point you at. Email us and we will tell you when the trial opens.
