The burgeoning artificial intelligence (AI) megatrend continues to fuel unprecedented demand for high-performance computing infrastructure, creating a dynamic battleground within the cloud computing sector. While established titans like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud maintain their dominance with impressive scale and profitability, two specialized newcomers, CoreWeave and Nebius, are rapidly expanding their footprints. These agile ‘neocloud’ players are posting triple-digit percentage growth rates that significantly outpace their larger counterparts, yet they operate in the red, channeling all available capital into scaling their operations to meet escalating demand.
Titans Maintain Dominance with Robust Profitability
Investing in cloud computing companies has become a primary avenue for gaining portfolio exposure to the AI megatrend. This is largely because most companies lack the extensive resources and specialized expertise necessary to construct and manage their own AI-centric data centers. Consequently, they turn to cloud computing operations to rent the essential processing power. Amazon Web Services, the undisputed leader in global cloud infrastructure, remains a critical profit engine for its parent company. In Q1, AWS accounted for a substantial 59% of Amazon’s operating income, with its revenue expanding at a robust 28% rate—its fastest growth in nearly four years.
Microsoft Azure, while not providing the same level of detailed financial disclosure as AWS or Google Cloud, reported an impressive 40% growth rate in its latest quarter. It is widely assumed by industry observers that Azure contributes significantly to Microsoft’s overall profitability, reinforcing the lucrative nature of the enterprise cloud computing business. Alphabet’s Google Cloud, though the smallest among the three titans, demonstrated the most rapid expansion, achieving an impressive 63% growth rate. This acceleration was partly bolstered by its Tensor Processing Units (TPUs), powerful computing units specifically designed to outperform general-purpose GPUs from a cost perspective when handling deep learning and matrix mathematics workloads. Google Cloud’s strategy now includes directly selling these proprietary AI chips to other companies, rather than solely renting out their processing power. As noted by Keithen Drury for The Motley Fool on June 12, 2026, this external sales contribution can make the precise gauging of the infrastructure business’s standalone performance ‘a bit murky.’ Nevertheless, Google Cloud remains the fastest-growing of the three despite its smaller size.
The consistent, strong performance and high profitability across AWS, Azure, and Google Cloud firmly establish cloud computing as a viable standalone business, offering a stable and profitable foundation for investors seeking exposure to the AI revolution.
Neoclouds Emerge with Hyper-Growth Strategies
Against this backdrop of established giants, CoreWeave and Nebius have strategically positioned themselves as ‘neocloud’ companies—specialized cloud computing providers with an exclusive focus on AI workloads. While their specific business models differ, both have successfully attracted major tech players, including Microsoft and Meta Platforms, as clients. These large customers, despite possessing their own extensive data centers, find immense value in the ability to rapidly obtain additional, specialized computing power without the significant capital expenditure and time required to build it themselves. This flexibility and speed are key differentiators for the newcomers.
The burgeoning demand from these and other clients has translated into what the source describes as ‘jaw-dropping growth rates’ for CoreWeave and Nebius, especially when compared to the more mature legacy cloud companies. In Q1, CoreWeave’s revenue surged by an astonishing 112% year over year. Nebius showcased even more explosive expansion, with its revenue soaring by an extraordinary 684% during the same period. These figures dramatically outpace the growth rates of the established cloud giants, underscoring the intense focus and agility of these specialized AI-centric providers in a rapidly expanding market.
Rapid Expansion Outpaces Profitability
Wall Street analysts are equally optimistic about the future trajectories of CoreWeave and Nebius, projecting continued aggressive expansion. For 2026, analysts expect CoreWeave to achieve 147% revenue growth, followed by 97% in 2027. Nebius is anticipated to maintain an even more accelerated pace, with 2026 growth estimates hovering around 551% and 2027 projections at 224%. Despite these impressive revenue forecasts, a critical distinction separates these newcomers from the established titans: neither CoreWeave nor Nebius is currently expected to be profitable. The source explicitly states that they are ‘spending every bit of money they have to expand their cloud footprints.’
This aggressive reinvestment strategy, prioritizing market share capture and infrastructure build-out over immediate earnings, represents a ‘central risk’ for potential investors. The companies are essentially deferring profitability to meet the insatiable demand for AI computing power, a stark contrast to the mature, highly profitable operations of AWS, Azure, and Google Cloud, which have long established their market dominance and robust revenue streams. The high-stakes gamble is that by rapidly scaling now, they can secure a significant position in the burgeoning AI infrastructure market before it fully matures.
For investors, the choice between these two cohorts presents a clear risk-reward profile. The legacy cloud companies continue to represent ‘fantastic investments’ due to their stability, immense scale, and proven profitability, offering a more conservative yet reliable path to AI exposure. However, for those with a higher risk tolerance and a pursuit of potentially ‘greater long-term upside potential,’ Nebius and CoreWeave emerge as compelling, albeit speculative, stock picks. The ongoing competition underscores the dynamic nature of the AI infrastructure market, where both entrenched powerhouses and nimble specialists are vying to capitalize on one of the most transformative technological shifts of the era. The ultimate success of these newcomers hinges on their ability to translate explosive growth into sustainable, profitable operations, a challenge that will define their long-term viability against the formidable presence of the cloud computing titans.
