Frequently Asked Questions

What does the preseason offer include?

50% off your first purchase of Gridiron Edge Pro, on either plan. Monthly bills $7.50 for the first month and $14.99 a month after that; annual bills $75 for the first year and $150 a year after that. The discount applies to the first purchase only, and the offer runs through September 10, 2026.

What is actually free without Pro?

The game edges board is free permanently — our model's win probability against the live Kalshi price on every game, moneyline, spread and total, with no signup. So are the full-slate model lines, power rankings, MVP market reads and all 32 team hubs. Win totals, championship probabilities and player projections are fully open through Week 1, and keep their top 8 rows free after that.

What does Pro add?

The full depth of the futures, championship and projection boards, edge alerts in Discord the moment a gap opens, the cross-market arb scanner, Thee Oracle, the commodity and crypto edge engines, and agent access to the same model over MCP so tools like Claude or ChatGPT can call it directly. All 25 quant tools are included.

How accurate is the NFL model?

In a walk-forward backtest of 3,266 games from 2013–2024, the model called winners straight up 59.6% of the time with a 0.236 Brier score, using no market line as an input. Accuracy rises with the model's own stated confidence, reaching 71.5% on games where it flags an edge above 20 points.

Can I cancel?

Yes — any time from your account page, and you keep access through the end of the period you already paid for. There is no contract and no cancellation fee.

Are these markets legal to trade?

Kalshi is a CFTC-regulated exchange available in all 50 states, and its contracts settle at $1 or $0 rather than against a house line. We publish analysis; where you take a position is your call. Contracts can settle at $0 — trade responsibly.
