Who's next

▼ IONQ IonQ — impact -93 · confidence medium · horizon immediate · 1st order
IonQ's share decline raises its cost of equity, making funding ongoing cash burn more dilutive.
Chain: shares fall ten percent in one session → market capitalization and equity currency decline → future at-the-market issuance raises fewer dollars per share → dilution per dollar of cash burn rises
What would break the call: A large government or enterprise contract award restores the share price and removes near term financing pressure.
▼ RGTI Rigetti — impact -70 · confidence high · horizon immediate · 2nd order
IonQ's decline weakens quantum investor appetite, raising Rigetti's equity financing costs as investors demand greater compensation.
Chain: IonQ decline sets sector sentiment benchmark → quantum peer valuations re-rate lower together → Rigetti equity raise proceeds shrink per share → cash runway funding becomes more dilutive
What would break the call: Rigetti posts a technical milestone or bookings beat that decouples its stock from IonQ moves.
▼ QBTS D-Wave — impact -65 · confidence high · horizon immediate · 2nd order
IonQ's decline weakens quantum confidence, reducing D-Wave's equity financing proceeds for technology investment.
Chain: flagship quantum name drops sharply → sector risk appetite falls broadly → D-Wave share price tracks peer decline → equity program raises less cash for development
