Pre-revenue quantum companies fund themselves by issuing stock, so dilution and insider selling are the activity that actually moves these names. This tracker aggregates the last 30 days of SEC filings across all 12 pure-play quantum stocks: open-market insider buys and sells (Form 4) plus new shelf registrations and at-the-market offerings (S-3 / 424B / foreign-issuer SUPPL) that signal upcoming dilution.
As of , the latest issuers in the tracked filings are XNDU: 424B3 (ATM prospectus), filed ; IONQ: 424B5 (ATM prospectus), filed .
A filing does not prove shares were sold. Shelf registrations describe potential registration capacity, and offering prospectuses do not establish completed issuance or the amount of dilution.
