The quantum computing sector is facing a pivotal moment with the Nasdaq debut of Quantinuum under the ticker QNT, valued at up to $14.3 billion. This event comes after a $2 billion federal grant announcement that boosted stocks of quantum firms like IonQ, D-Wave, and Rigetti, which collectively represent about $48.24 billion in market capitalization. Quantinuum's entry could either bolster the sector by attracting new institutional investments or lead to a cannibalization effect, where funds are redirected from existing players like IonQ and Rigetti. The IPO is notable as it is the first traditional public offering for a full-stack quantum company, backed by Honeywell International and JPMorgan. The market is closely watching whether QNT will open above its $53 to $55 IPO range, as its performance could set the tone for other quantum stocks.
