What each instrument actually is
An IPO or STAR Market listing records proceeds from a first public sale of shares. A SPAC merger may be announced long before it is priced, and the announcement itself has no cash value. An at-the-market programme is an authorisation to issue shares up to a ceiling over time. A follow-on public equity offering is a discrete later sale of shares. Our round field preserves that wording instead of normalising all four into a generic funding round.
This is why two rows for the same company in the same year are not automatically duplicates. A listing and a later offering are genuinely different events; an announcement and a priced close of the same merger usually are not. The de-duplication rule is applied to reports, not to instruments.
Why we keep them
Deleting public-market rows would make the ranking look more like a venture database, but it would understate the capital available to the companies that actually build hardware. It would also create a strange discontinuity: a company would appear in the table while private and vanish once listed. Keeping the rows with an instrument label is the only option that lets a reader construct either view.
The government capital tracker and the annual reviews both use the same classification, so a figure quoted from one page can be traced back to the same row on another.
The comparison rule
If you compare a private Series B with an ATM ceiling, say so. If you want a private-capital-only comparison, exclude the public instruments and note the exclusion in your citation. We do not provide a single toggle that silently changes the total, because the instrument mix is part of the finding rather than a filter to be hidden.

The practical takeaway
The instrument field is not decoration. It is the difference between a defensible funding table and a number that changes meaning every time someone reads it.
