A SPAC listing followed by a much larger follow-on offering makes the distinction between listing proceeds and later equity cash unusually clear.
This profile is a single-company view of the same public ledger that builds the global ranking. Figures are disclosed amounts, not valuations; an empty cell means the source did not publish a number.

The ~$650M attached to this SPAC listing is transaction proceeds, not a priced venture round, and it is the entry that moved IonQ from a private hardware startup into the public-market cohort. Trapped-ion systems were still sold mostly as cloud access at the time, so a listing changed the funding comparison more than the product roadmap. We keep it here because later equity offerings only make sense against this baseline, but we never add it to a venture-round total.
A ~$1.0B public equity offering is one of the largest single rows in the whole dataset, and it is balance-sheet cash raised from public markets rather than a priced venture round. IonQ had already listed via SPAC in 2021, so this offering is a follow-on that changes the denominator for every comparison with private trapped-ion peers. SEC filing coverage is the cited source, which is why the confidence flag is firmer than for press-reported rounds.
We keep listing proceeds and the public equity offering as two separate instruments. No implied valuation multiple is applied to either figure.
