Quantum Computing Inc (QUBT) Skyrockets 2,500%: $750 M Windfall, Quantum Breakthroughs & Bubble Fears

Quantum Computing Inc.’s share price has been on a meteoric rise throughout 2025, turning a little-known small-cap into one of the year’s most explosive tech stocks. Over the past 12 months, QUBT surged by over 2,500%, far outpacing even high-flying peers in the quantum computing spacets2.tech. The stock climbed from mere cents to the mid-$20s, hitting an intraday high around $27ts2.tech. By early October 2025 its market capitalization swelled into the multi-billion range, a remarkable feat for a company with minimal revenues.

Quantum Gold Rush: D-Wave (QBTS) Skyrockets on Breakthroughs as Quantum Computing Frenzy Heats Up

D-Wave Quantum’s stock chart in the first week of October 2025 looked like something out of a sci-fi blockbuster – shooting upward to record levels. On Friday, October 3, shares hit an intraday high of $33.28 before closing at $32.70insidermonkey.com. Just two days earlier, on Oct 1, QBTS had been trading in the mid-$20s; by Oct 3 it was up roughly 30% for the week and nearly +300% year-to-datets2.tech. To put the trajectory in perspective, one year ago the stock was barely $1 – it has since multiplied over 30-foldfastcompany.com. This kind of explosive growth is virtually unheard of outside of penny-stock or cryptocurrency realms, and it underscores both the euphoria around quantum computing and the speculative nature of the rally.

Quantum Computing Inc. (QUBT): 2025’s Wild 3,200% Quantum Stock Surge – Boom or Bubble?

Quantum Computing Inc. (QUBT): 2025’s Wild 3,200% Quantum Stock Surge – Boom or Bubble?

QUBT’s share price has been on a rollercoaster in 2025, reflecting both speculative hype and sudden reversals. After an explosive rally in late 2024, QUBT entered 2025 at lofty levels and promptly cratered: shares plunged about –37% in January 2025 and –42% in February 2025 Portfolioslab, wiping out roughly two-thirds of its value in the first two months. This steep pullback from the late-2024 peak was likely a combination of profit-taking and sober reflection on the minimal fundamentals supporting the price.

Quantum Computing Inc (QUBT) Stock Skyrockets on $500M Fundraising and New Tech Debut – Can the Rally Last?

Quantum Computing Inc (QUBT) Soars 24% on $500M Funding & New “Quantum Secure” Tech – Will It Hit $40?

Quantum Computing Inc has a multi-billion-dollar market cap, driven by the funding and product buzz. On Oct 2 it closed $19.98 stoculator.com. Year-to-date through early October 2025 it is up ~54% finviz.com. However, QCi’s fundamentals remain speculative. Q2 2025 results showed only $61K in revenue and a net loss of $36.5M, largely due to mark-to-market warrant costs finviz.com. Operating expenses were $10.2M, more than double last year’s quarter finviz.com. Cash was $348.8M at June 30, 2025 after a $188M fundraising finviz.com. With the new $500M, QCi’s cash runway is very strong, bolstering its balance sheet even as revenue remains minimal quantumcomputinginc.com finviz.com.

Quantum Gold Rush: QUBT vs. D-Wave – Inside the High-Stakes 2025 Quantum Computing Showdown

Quantum Computing Inc. – Photonic Quantum Tech at Room Temperature: Quantum Computing Inc., branded as QCi, is a small-cap quantum technology company that has captured outsized attention due to its unconventional approach. Rather than using superconducting circuits or ion traps like many competitors, QCi focuses on photonic quantum computing – using particles of light passing through specialized optical chips to perform computations. The company’s core technology revolves around thin-film lithium niobate photonic integrated circuits nasdaq.com. This approach potentially offers a big advantage: QCi’s photonic qubits can operate at ambient room temperature, avoiding the need for the ultra-cold dilution refrigerators that systems from IBM, Google, D-Wave and others typically require nasdaq.com. By eliminating cryogenics, QCi aims to slash the cost and complexity of quantum hardware and allow easier scaling of quantum processors.
