How we know
Not rumours. Filings.
Filed with regulators
Companies and funds raising privately in the US must file a Form D, with the target and the amount raised so far.
Checked every day
New filings are read daily. A round drops off the list once it is fully raised or goes quiet.
Linked to the source
Every figure opens the original filing, so you can check it yourself before you act.
