## How the model works

With no news, the chance of hitting $1.5T by the date drifts along the by\_date decay. Reports of investors pushing the IPO price toward $1.5-1.6T are added on top, read through the news reading of valuation cuts.

- With no new event, the chance of hitting $1.5T by the date shifts to about 0 of the pace a constant hazard would imply as the window shrinks. DataSnack's author expected 1; the data say 0. A rough rule.
- Each full point of rise in the reading that the IPO valuation is being cut moves the chance by about 0 in log-odds in log-odds. DataSnack's author expected 0.5 in log-odds; the data say 0 in log-odds ± 2. A rough rule.
