How it works
Same engine behind every prediction, every sport.

Real matchup data

Confirmed starting pitchers, rotation averages when unconfirmed, live team and player stats pulled fresh for every slate.

10,000-run simulation

Every game gets its own Monte Carlo run — win probability, predicted score range, and player projections all come out of the same model.

It tells you when it's guessing

Every call is tagged toss-up, lean, or strong lean before the game starts — then graded against the real final score. The accuracy climbs with the tier, and you can check that yourself.

NEW — INCLUDED WITH EVERY PLAN

NexBet: the sim vs. the market

The engine runs every game 10,000 times. NexBet puts that number next to what the prediction market on Kalshi is actually paying — spread stripped out for a fair comparison — and sorts the slate by the size of the disagreement. Plain English, biggest gap on top, tomorrow's slate visible tonight.

An edge is a disagreement between model and market, not a guarantee. Prediction-market trading involves risk and is 18+. NexGame Lite may earn a commission on accounts or trades made through links on the NexBet page.

The sim has the Mariners winning 62 of every 100 games. The market is paying like it's 55.
Value: Mariners — +7.0 points.
