Will Quantum Computing Inc. Stock Rebound in 2026?

Quantum Computing Inc. (QUBT) has materially underperformed its quantum peers—shares are down ~23% YTD and nearly 50% from highs while D-Wave and Rigetti have surged—after the company reported roughly $500,000 of revenue over the past year even as its share count nearly doubled to fund operations. That dilution has left QUBT with a market cap of about $2.8 billion and an implied price-to-sales ratio near 3,300x, the largest premium in the group despite the smallest revenue base, prompting the analyst view that the name is speculative and likely driven by narrative rather than commercial traction. The piece recommends avoiding QUBT for prudent investors, noting potential fleeting rebounds on headlines and suggesting broad-tech exposures (Amazon, Alphabet, Microsoft, IBM, Nvidia) as more sensible ways to access the quantum/AI opportunity.

Analysis

Quantum Computing Inc. (QUBT) has materially underperformed its pure-play peers in 2025: QUBT is down ~23% year-to-date and nearly 50% off its all-time highs while D-Wave and Rigetti have risen ~232% and ~78% YTD and IonQ is up ~27%. The company reported roughly $500,000 of revenue over the last year even as its outstanding share count “almost doubled,” creating acute dilution pressure and investor fatigue.

Management projects a $66 billion TAM for its photonic integrated circuits by 2032 and highlights partnerships with NASA, Accenture, BMW and EY, yet these relationships have not translated into material enterprise sales to date. Market pricing now implies a market capitalization near $2.8 billion and an implied price-to-sales ratio of ~3,300x, the largest premium among its quantum cohort despite the smallest revenue base.

The analyst view in the article characterizes QUBT as speculative and narrative-driven, warning rebounds would likely be headline-driven and ephemeral and forecasting continued selling pressure absent commercial traction. As a result, the piece recommends avoiding QUBT in favor of diversified large-cap tech exposures (Amazon, Alphabet, Microsoft, IBM, Nvidia) that provide quantum/AI upside with established revenue streams and lower idiosyncratic dilution risk.

Key Decisions for Investors

• Avoid initiating new long positions in QUBT given only ~$500k in trailing annual revenue, a near-doubling of shares outstanding, and an implied P/S of ~3,300x which indicate extreme valuation risk
• If currently long, consider trimming or hedging exposure and require clear, sustained metrics before re-accumulating—specifically sequential revenue growth, a demonstrable slowdown in share issuance, and conversion of partnerships into paying enterprise contracts
• Rotate discretionary quantum/AI exposure toward large-cap tech names listed in the article (Amazon, Alphabet, Microsoft, IBM, Nvidia) to capture upside while maintaining diversified revenue streams and lower execution/dilution risk
• Short-term traders should treat any QUBT rallies as headline/narrative driven, use tight risk controls, and avoid basing positions solely on promotional partner announcements absent verified commercial adoption
