JetZero last marked at $36.17 per share on 5 August 2026, an implied valuation of $686.2M. Secondary Flow refreshes this mark every day from publicly observable private-market activity. Private-company prices are indications rather than executed trades: they carry wider spreads than listed equities, they can move without any news, and a transfer still needs the issuer's consent to settle.

Secondary Flow is a research tool, not a broker-dealer or a marketplace, so it does not execute transactions in JetZero or any other private company. Private-company shares typically change hands through a company-approved tender offer, a direct transfer subject to the company's right of first refusal, or a regulated secondary marketplace, and most transfers require issuer consent. Secondary Flow tracks the resulting prices.
