Quantum computing is still anyone's game. Big. Small. In between.
Broadly speaking, the latest earnings reports were unremarkable. For now, the sector remains deeply unprofitable, and quantum technology is only starting to break out of the lab. What this earnings season did show, however, is that quantum's credibility is steadily growing and use cases are beginning to crystallize.
As both Wall Street and the White House increasingly embrace the technology, market share remains up for grabs -- the industry is projected to reach $43 billion to $71 billion by 2035. But investors shouldn't assume IBM and other big names will be the automatic winners. In fact, second-quarter earnings suggest that pure-play companies -- long viewed as riskier investments due to their sole focus on quantum technology -- are the ones to watch.
Those pure-play companies, many of them newly public, took center stage this earnings season. Quantinuum, which made history in June with the industry's first traditional initial public offering, saw its shares rally 28% for their best day on record after its first report as a public company. The quarter's growth was driven by steady, recurring cloud computing revenue rather than one-off system sales.
And in a key sign of quantum's growing legitimacy, Quantinuum struck a partnership with Oracle to integrate quantum hardware directly into data centers, marrying classical and quantum systems to realize the hybrid computing model that experts view as the future of the field.
The earnings season also featured early-stage reports from Infleqtion, Horizon Quantum, and Xanadu Quantum Technologies. Infleqtion said its quarterly revenue was "100% organic and entirely driven by quantum." Horizon and Xanadu told a different story, with figures reflecting the heavy costs of ongoing investment. Horizon, for instance, generated zero revenue while its research and development expenses doubled from last year.
For now, though, narratives about customer demand and technical advances matter more than the raw numbers, because commercial traction is key for staying afloat.
Case in point: The second quarter brought continued progress toward error correction and scaling, a crucial step toward broader adoption and eventual commercialization.
While these smaller, pure-play companies sit on weaker financial footing than established tech giants, their advantage is in their rapid technical and commercial progress -- especially compared with larger, more diversified players.
Microsoft, for instance, has skin in the game but has yet to start selling physical systems. The story is similar for Alphabet-owned Google, which may have a robust research unit, but builds its systems largely for internal use rather than commercial clients.
As for IBM, its latest quarterly results -- and the historic selloff they triggered -- serve as a stark reminder that quantum remains a minor fraction of the overall business. The company was bogged down by weak performance in its core infrastructure segment, overshadowing the rest of the report.
Among the longest-lived quantum pure plays, IonQ and Rigetti Computing, showed signs of commercial progress in the second quarter. IonQ delivered $80.1 million in revenue alongside solid organic growth, driving what CEO Niccolo de Masi called "the strongest quarter" in company history. Although Rigetti generated only a fraction of IonQ's revenue -- $5.1 million -- the company said it was fulfilling system orders, including a major sale to a research center in India.
However, D-Wave Quantum, another industry stalwart, offered a reminder that results will remain lumpy as the industry navigates its growing pains. The company's first-half bookings surged 1,120% year-over-year, but that growth was heavily concentrated in the first quarter
Looking forward, investments and partnerships like the Oracle deal will be a key foundation for improving quantum's credibility, especially among these emerging pure-plays. In the second quarter, a $2 billion Commerce Department funding package was followed by two executive orders establishing quantum development and post-quantum cybersecurity as national priorities.
With most companies sticking to their technical road maps, increasingly advanced systems are set to roll out over the next few years, laying the groundwork for quantum to take off by the end of the decade.
Across every architecture and business model, the race is on -- and the technology's growing legitimacy is undeniable. Quantum executives have repeatedly said the real winners will be those that win over customers. For now, the field is wide open.
