PsiQuantum funding profile

Its disclosed total is dominated by one Series E, so the profile is really about what a single fab-aligned financing can do to a ranking.

Series C~$450M

BlackRock led a ~$450M Series C in mid-2021, an unusually large cheque for a photonic architecture that had not yet shipped a commercial machine. PsiQuantum was already describing utility-scale sites rather than incremental qubit counts, so the money is best read as pre-financing fabrication and facilities. In our ledger it is the earlier of two billion-dollar-class photonic entries; the gap to the later Series E says more about the cash demands of a fab-aligned roadmap than about a repricing of technical risk.

Series E~$1B

BlackRock returned as lead on a ~$1B Series E, with NVIDIA and other reported participants, making this the largest priced private round in our ledger. Four years after the Series C, PsiQuantum had announced utility-scale sites in Brisbane and Chicago; the money is therefore tied to facilities and foundry partnerships, not to a qubit-count milestone. Because the syndicate is only partially reported, we name the confirmed participants and leave the rest unattributed.

Government funding (CHIPS Act LOI)Not disclosed

For PsiQuantum, the November 2026 letter of intent is a siting story rather than a funding story: the company had already announced utility-scale photonic sites in Brisbane and Chicago and closed a $1B Series E in 2025. A CHIPS-related notice is relevant to which domestic fabrication partnerships are encouraged, not to the company's cash balance. Our ledger shows it with an empty amount column and a month-precision date so it can never be summed with the priced rounds.

Editorial caveat for this company

The Series E is a single reported figure with no post-money valuation attached. We do not infer one, and the profile deliberately has no valuation field.
