QL IPO Window Index

Is the IPO window open?

One number, computed nightly from 1,900+ tracked private companies: how many books are IPO-ready, who is actually filing, whether private marks leave pricing headroom against live public comps, and which way the private market is moving. Every driver is public; thin data drops out instead of being guessed.

The QL IPO Window Index is a research gauge computed nightly from disclosed data and public-market heuristics. It is NOT a prediction that any company will or will not list, a statement about any issuer's plans, or investment advice; private marks and disclosed figures are not real-time.
