Staged Conviction Model
What Probability/Conviction Is Needed for the Bet to Pay Off?

Assign your conditional conviction per stage
Each input is P(clears this stage | previous already cleared). The chain multiplies into a cumulative probability of reaching each valuation.

Amazon (~$2T) · 310M users
Stages are sequential: clearing each one is conditional on the previous. The remaining probability mass is the implicit chance of failing before reaching the first hurdle.
