What "value" actually means

A price has "value" when the probability it implies is lower than your own genuine estimate of how likely the outcome is. Over the long run, consistently betting positive-value prices is the only mathematically winning approach — betting randomly on zero or negative-value prices loses money on average, no matter your current streak.

The confidence trap

This tool is only as good as your estimate. If your 45% is really an optimistic hunch rather than solid analysis, the tool will hand you false confidence. Discipline means slightly underestimating, not inflating your read to manufacture "value."

Frequently asked questions

Where does my probability estimate come from?

From you — your read on the matchup, stats, injuries, and so on. The tool just compares your number to the one implied by the price.

Does value guarantee a win?

No. A single bet stays random. Value is a long-run concept: it improves your odds across many bets, not the outcome of one.
