How Quantum Computing is Funding Its Next Quantum Phase

Quantum Computing Inc. QUBT or “QCi” has rapidly strengthened its financial foundation, using an aggressive capital strategy to secure a strong cash position. Through the months of 2025, the company increased its cash and equivalents to $352.4 million and investments to $460.6 million, bringing total liquidity to roughly $813 million. It is followed by an additional oversubscribed $750 million private placement, which pushed current liquid assets well above $1.5 billion. This dramatic expansion of cash runway provides QCi the multi-year stability required to fund deep-tech development cycles, where commercial revenue remains modest. 

The large raises also serve as validation, signaling institutional investors’ conviction and de-risking the path toward commercialization while allowing the company to operate with minimal debt. With operating expenses remaining in the $10 million range per quarter, QCi’s cash burn is meaningful but manageable given its sizable liquidity. 

This positions the company to invest aggressively in R&D, scale its thin-film lithium niobate photonics foundry, attract technical talent and pursue strategic growth opportunities without relying on near-term revenue spikes or additional financing. Operating in an industry defined by long development horizons and high capital intensity, QCi’s strengthened balance sheet has become an asset. This materially enhances its ability to execute on its quantum commercialization roadmap.

Peer Update

In the third quarter, D-Wave Quantum QBTS reported a record consolidated cash balance of $836.2 million, representing a substantial increase from about $29.3 million in the prior-year quarter. This growth was driven primarily by cash proceeds from warrant exercises, which contributed $39.9 million during the quarter and an additional $21.3 million after quarter-end through early November. This strong cash position provides D-Wave with significant liquidity, reflecting both operational progress and strategic balance sheet management. This also underscores QBTS’ ability to support ongoing development and commercialization efforts.

In the third quarter, IonQ IONQ reported a pro-forma cash, cash equivalents and investments balance of approximately $3.5 billion following the completion of a $2 billion equity offering in October 2025, one of the largest single institutional stock investments in quantum industry history. This reflects strong investor demand for IonQ’s growth narrative and provides significant liquidity to support its long-term commercialization plans and acquisitions. This capital strength is a cornerstone of IONQ’s strategy, enabling continued R&D investment, global expansion and execution of strategic deals while managing ongoing operating losses.
