It’s 5:45 a.m. ET on Thursday, December 18, 2025, and “quantum stocks” are waking up to a familiar push–pull: big long-term promises (quantum advantage, new enterprise customers, government contracts) colliding with near-term market nerves about tech spending, rates, and whether the latest computing boom is getting ahead of itself. Reuters
Below is the most current news, forecasts, and analysis in circulation today (12/18/2025) shaping the U.S.-listed quantum pure plays—IonQ (IONQ), D-Wave Quantum (QBTS), Rigetti Computing (RGTI), and Quantum Computing Inc. (QUBT)—plus what investors are watching next.
Market backdrop: why “quantum stocks” are moving with (and against) big-tech sentiment
Quantum computing equities have been trading like high-beta tech: when risk appetite improves, they can rally fast; when the market turns cautious, they can fall harder than the indexes.
That dynamic matters this morning because global markets are trying to stabilize after a renewed wave of AI-spending anxiety bruised tech, while traders brace for a heavy slate of central-bank decisions and U.S. inflation data due later today—exactly the kind of macro setup that can amplify volatility in speculative growth themes.
In plain terms: even on days with legitimate quantum-company headlines, quantum stocks can still trade like a referendum on broader tech sentiment.
Today’s headline catalyst: IonQ expands its European footprint with a $60M+ QuantumBasel deal through 2029
The clearest company-specific news hitting the tape today centers on IonQ (IONQ).
IonQ announced an expanded agreement with QuantumBasel (the quantum initiative at Switzerland’s uptownBasel innovation campus), extending the partnership through 2029 and bringing the total deal value to over $60 million. The agreement also transfers ownership of an existing IonQ Forte Enterprise system and secures a next-generation IonQ Tempo system for the Swiss site, while expanding joint workstreams aimed at hybrid quantum–classical techniques and AI/LLM optimization.
Why this matters for IonQ stock (and quantum stocks broadly)
This isn’t just “another partnership” headline. It touches three things public-market investors track closely in quantum names:
- Enterprise-grade deployments: on-site systems and multi-year commitments are a stronger proof point than pilot projects alone.
- Commercialization timeline: long-dated contracts help tell a “repeatable revenue” story in a sector often criticized for being perpetually pre-commercial. Investing.com Australia
- AI adjacency: explicitly framing quantum work around boosting AI workflows (hybrid methods, model optimization) aligns with the market’s current obsession—while still leaving room for skepticism if “AI + quantum” reads as buzzword stacking. Investing.com Australia+1
Analyst forecasts today: “Buy quantum” gets louder—especially for IonQ and D-Wave
A major part of the quantum-stocks conversation today is Wall Street’s latest wave of coverage initiations and 2026 framing—and it’s notably constructive on the sector’s leaders, even while acknowledging it’s early and unprofitable.
Wedbush’s positioning: Outperform on IONQ, QBTS, RGTI; Neutral on QUBT
According to coverage summarized today, Wedbush launched coverage of the quantum computing sector, initiating Outperform ratings on IonQ, D-Wave, and Rigetti, while starting Quantum Computing Inc. at Neutral. In Wedbush’s view, quantum computing is moving from research toward early commercial applications, with spending rising from a small base as the technology matures.
Wedbush also framed a measurable adoption aspiration: quantum systems could account for just under 2% of total compute expenditures by 2030 across the covered names—an aggressive narrative that helps explain why quantum stocks can command huge valuations long before profits appear.
Barron’s today: Buy IonQ and D-Wave; Hold Rigetti—D-Wave growth forecast stands out
A key read circulating today is a Barron’s breakdown of how analysts are “playing quantum stocks in 2026.” The thrust: analysts are positive on the theme, but they’re making clear distinctions among the pure plays.
- D-Wave Quantum (QBTS) gets highlighted for its commercial positioning and balance-sheet strength, with an analyst-cited expectation of ~73% compound annual revenue growth through 2030 (a big-number forecast that can fuel sentiment—if execution matches the narrative).
- IonQ (IONQ) is framed as the sector’s heavyweight, benefiting from partnerships and a balance sheet positioned to fund R&D and commercialization.
- Rigetti (RGTI) is more divisive in the analyst community, with a more cautious “hold” posture from at least one firm cited due to business-model and customer concentration concerns. Barron’s
If you’re tracking quantum stocks for forecast-driven moves, this analyst split matters: in early-stage tech, narrative leadership often influences share prices nearly as much as quarterly fundamentals.
IonQ technical/stock-read signals: IBD flags strengthening Relative Strength rating
Alongside fundamentals and analyst notes, traders also watch technical grades that can impact momentum flows.
Investor’s Business Daily reported that IonQ’s Relative Strength (RS) Rating rose to 86 (from 78), placing it in a higher performance percentile versus other stocks over a 52-week measurement window. IBD also noted IonQ’s most recent report showed a sharp sales increase (222%) even as earnings growth remains a challenge—an “early commercialization” profile that often produces big price swings.

Where each quantum stock stands today: the fast, practical snapshot
IonQ (IONQ): strongest “enterprise deployment + global expansion” storyline today
What’s new today: the QuantumBasel expansion through 2029 and the Tempo system commitment.
What investors debate: whether partnerships translate into durable revenue scaling fast enough to justify the valuation—especially during broader tech de-risking.
D-Wave Quantum (QBTS): analysts increasingly point to “commercial readiness,” but the bar is rising
What’s driving the tape today: analyst framing that positions D-Wave as a leading commercial platform (and a preferred “buy” in some 2026 playbooks), including a standout long-range growth forecast. Barron’s
What investors debate: how much revenue can expand before competitive architectures (and customer hesitancy) slow the curve.
Rigetti (RGTI): the “hold vs. outperform” battleground name
Today’s narrative: it’s frequently mentioned as a major U.S. pure play, but is also the name where analyst conviction appears less uniform in today’s coverage discussion.
What investors debate: concentration risks (including reliance on certain contract types) versus the upside if broader enterprise adoption accelerates.
Quantum Computing Inc. (QUBT): the high-volatility outlier with a more cautious stance from at least one major note today
Today’s narrative: coverage discussed today includes a more reserved view on QUBT compared with the other three.
What investors debate: whether its technology path produces scalable commercial products—or whether the stock remains primarily sentiment-driven.
The ETF angle today: QTUM holdings updated (for investors who want diversified “quantum exposure”)
For investors who want “quantum stocks” exposure but don’t want all the single-name risk of the pure plays, the Defiance Quantum ETF (QTUM) remains one of the most referenced baskets in the space. Defiance’s published holdings are dated as of 12/18/2025, underscoring that the fund’s composition is actively maintained and can shift over time. defianceetfs.com
This matters because many “quantum ETF” products blend:
- true quantum hardware/software plays,
- AI/ML infrastructure companies,
- semiconductors and enabling tech.
So QTUM can behave less like a pure quantum bet and more like a hybrid AI/innovation factor depending on holdings and weights at any moment.
What to watch later today (Dec. 18): the catalysts that can move quantum stocks even without quantum news
Because quantum stocks often trade as high-beta tech, today’s macro calendar can matter as much as any single press release:
- U.S. CPI (November) later today (per Reuters’ global market preview), which can shift rate expectations and risk appetite.
- Central bank decisions in Europe and the U.K. that can affect global rates, currencies, and tech multiples.
- Ongoing AI-spending scrutiny (and spillover to adjacent themes like quantum) after high-profile tech capex debates.
Bottom line for quantum stocks today: bullish forecasts, real contracts, and still a volatility-first trade
As of this morning (12/18/2025), the quantum sector has two powerful forces operating at once:
- A strengthening fundamental story in pockets—highlighted by IonQ’s expanded European deployment and multi-year commitment with QuantumBasel.
- A market environment that can punish long-duration stories quickly, especially when the broader tech tape is anxious about spending cycles and rates.
That combination is why quantum stocks can look like the next computing revolution one day—and trade like leveraged sentiment vehicles the next.
