The quantum computing sector experienced explosive growth in 2025, driven by significant technological breakthroughs. Stocks of startups like Rigetti Computing and D-Wave Quantum skyrocketed by over 600%. Even Alphabet, Google’s parent company, saw its shares rise nearly 90%, buoyed by the AI wave and its advanced quantum chip, Willow.
However, market analysts suggest a surprising shift may be coming in 2026: the spotlight could turn to an established tech titan, International Business Machines (IBM).
Despite a period of stagnation in the 2010s due to sluggish growth in its legacy businesses, IBM, under CEO Arvind Krishna, has been reinventing itself. While its pivot to cloud and AI has captured attention, a quieter, deeper transformation has been underway in quantum computing.
IBM laid foundational work early, offering public cloud access to a quantum computer in 2016. It then launched the industry’s first commercially viable quantum computer, the IBM Q System One, in 2019. The innovation pace continues. In November 2025, IBM unveiled the IBM Quantum Nighthawk, a 120-qubit processor capable of running circuits 30% more complex while maintaining low error rates. The company’s roadmap is ambitious: achieving “quantum advantage” (where quantum computers outperform classical ones on specific problems) by the end of 2026, and delivering the first fault-tolerant quantum computer by 2029.
Unlike many cash-burning quantum startups, IBM stands on solid financial ground. For the first nine months of 2025, it reported revenue of nearly $48 billion, a 6% year-over-year increase. More importantly, net income reached $5 billion, surging 61% from the prior year. This profitability provides a durable engine to fund long-term, capital-intensive quantum research—a luxury most pure-play competitors lack.
While quantum revenue isn’t broken out in earnings reports, IBM’s financial health is a strategic asset.
From a valuation perspective, IBM presents a compelling case. Its P/E ratio of around 36, while not cheap, is grounded in actual earnings—a stark contrast to startups that lack profits. Its Price-to-Sales (P/S) ratio, just above 4, looks like a bargain compared to the triple-digit P/S multiples of some quantum peers. This lower sales multiple suggests less vulnerability if investor sentiment towards high-flying, unprofitable tech stocks sours.
Compared to the quantum efforts of behemoths like Alphabet (market cap: $3.8 trillion, P/S: 10), IBM’s ~$285 billion market cap offers more room for growth. Alphabet’s sheer size creates a higher barrier for its stock to double again. In contrast, IBM’s relatively smaller scale, combined with its synergistic cloud, AI, and quantum enterprises, allows for potentially more agile and impactful stock price appreciation driven by quantum progress.
In summary, IBM emerges as a uniquely positioned contender for 2026. It may lack the sheer growth potential of startups or the vast resources of Alphabet, but it offers a rare blend of proven quantum technology, financial stability, and reasonable valuation. As the market digests the 2025 run-up in pure-play quantum stocks, investors may increasingly seek proven operators with both the capability to innovate and the balance sheet to survive the long quantum journey. IBM, the “impossible” dark horse, is quietly assembling the pieces for a potential breakthrough year.
