Which billion-dollar marks are most overdue for a fresh price?
A weekly ranking of the tracked unicorns by how long since they last raised — the age of the disclosed mark. An old mark isn't necessarily wrong, but it's untested: the next round, secondary, or IPO is where the real number gets discovered, and the oldest marks carry the most re-pricing risk. The forward-looking companion to the Down-Round Ledger, which catches marks after they fall.

Decacorn Tiers.The Stale Marks Watch ranks companies QuantLogix tracks by the age of their disclosed valuation mark. Mark age measures price-discovery recency, NOT overvaluation — an old mark can be conservative or stale-high, and this board does not claim to know which. It is not a statement about any company's finances, and not investment advice; disclosed figures are not real-time.
