9 ‘Omniscaling’ Companies Are Reshaping the Global Economy

You may have heard of “hyperscalers.” Now, the global economy is being reshaped by “omniscalers.”

Omniscalers are a group of nine companies that are not only among the world’s biggest investors, but are also playing simultaneously across the world’s most important “arenas.” We define an “arena” as industries with the highest growth rates and the most competitive dynamism, where market-share changes are the norm.

We are perhaps used to Amazon being both the world’s biggest e-commerce company and the leader in cloud. But the Tesla-plus-SpaceX ecosystem now spans AI, digital media, robotics, EVs and space—almost systematically ticking the boxes of the new arenas. These two omniscalers are joined by Alibaba, Alphabet, Apple, Huawei, Meta, Microsoft, and Samsung. Six of them are based in the United States, and the other three in Asia.

The emergence of omniscalers signals a new kind of economy of scope and scale. Omniscalers can certainly resemble conglomerates, deploying capital across diverse businesses. They differ, however, in how they scale and in the capabilities they carry across arenas. Omniscalers can deploy large pools of cash into long-payback bets. Equally importantly, they benefit from data and platform network effects, where large user bases generate data that improves products, attracting more users and partners. Today’s omniscalers can also reuse infrastructure across arenas, such as cloud and compute, and even logistics networks, so new businesses start with built-in capabilities and distribution. That lowers the marginal cost of expansion. Incremental capital often builds on existing platforms instead of starting from scratch, matching the escalatory logic of arena competition. 

Omniscalers integrate these advantages and capabilities, even across arenas, through sustained R&D, capital expenditures, and M&A. 

As they scale, omniscalers can blur arena boundaries, influence investment-intensity levels, and disrupt value-chain structures. At the same time, scale alone is neither necessary nor sufficient for success in arenas. Many large companies do not scale across arenas. Meanwhile, we see new entrants continue to gain traction. Recent examples include well-funded younger AI players such as Anthropic and Perplexity; humanoid-robotics entrants such as Figure; fast-scaling EV challengers such as Zeekr (later acquired by Geely); and space players such as Rocket Lab. As escalatory investments reach new heights in arenas with omniscalers, competition isn’t quelled; it’s changing.

Being an omniscaler is inherently neither good nor bad. But understanding the emerging dynamics of omniscalers is increasingly important.

Nine omniscalers now span many arenas—and often lead them

We analyzed nine omniscalers, though there may be more. Our so-called “omni-9” are Alibaba, Alphabet, Amazon, Apple, Huawei, Meta, Microsoft, Samsung, and Tesla. Within this group, two operate as broader ecosystems or clusters of companies in which formally separate entities share leadership, capital, and capabilities. They are the cluster of companies founded by Elon Musk (Tesla and SpaceX, including xAI) and Jeff Bezos (Amazon, Blue Origin, and Project Prometheus).

We defined omniscalers based on two simple criteria: they ranked among the top 30 global spenders on combined R&D and capital expenditures in 2024, and they actively compete—meaning they generate publicly reported revenues—in at least three future arenas.

These criteria offer the benefit of simplicity, although we acknowledge there are challenges in the measurement itself. For one thing, arena participation can take many forms, not always generating revenue directly. For example, Apple is in chip design for its own internal use. Alphabet has invested in a long-duration energy storage company to accelerate progress in batteries.

The spending and earning criteria exclude several adjacent players for now, including both large spenders and multi-industry leaders. Some companies meet the spending threshold but remain focused outside arenas; one example is Toyota Motor (more than $30 billion in capital expenditures) in traditional automotive. Others meet the threshold but are concentrated in a single future arena, such as TSMC in semiconductors. Some are investing at scale in arenas close to their core business, like Walmart’s substantial growth in e-commerce and digital advertising, and may enter the omniscaler list as they expand into other areas.  Conversely, companies such as Tencent and Uber span multiple arenas but fall below the top-spender bar, and Nvidia—despite leading semiconductors and playing in several arenas—remains relatively capital-light and also falls below the investment cutoff.  Finally, inclusion depends on consistent public reporting. ByteDance may be a tenth candidate based on reported investment and multi-arena activity, but it remains outside the core list in the absence of comparable financial disclosures.

Omniscalers share a few common characteristics. First, their scope is wide. While our threshold was revenue generation in three arenas, by 2025, the average omniscaler participated in closer to six arenas. Alphabet reached nine.

Second, their depth can be substantial. Omniscalers account for a majority of revenue in cloud services, AI software and services, and digital advertising, for example. In each of these arenas, six or more omniscalers generate revenues. Yet they are more commonly new entrants in the other 15 arenas, where more focused players still hold sway. For instance, omniscalers hold just a small portion of global revenues in arenas like semiconductors, video games, and robotics, despite significant activity by them.

Third, the landscape is highly dynamic. Some arenas have become markedly more crowded in recent years, as seen in robotaxis—with Tesla and Amazon-owned Zoox intensifying competition with Alphabet-backed Waymo, the early leader (together with Baidu’s Apollo-Go). A comparable map in 2010 shows a narrower scope and reflects more tentative cross-arena moves.

Seen over the years, the expansion of these major companies almost looks like a convergence. For most omniscalers, a strong core business became a launchpad for cross-arena growth. Some started as digital natives, others from device- or hardware-led roots. Yet today, there is considerable overlap across digitization platforms and the AI foundation. Amazon and Alibaba moved from e-commerce into cloud and advertising. Microsoft expanded from software into gaming and cloud. Samsung is an established player in semiconductor value chains, while others developed proprietary chips or deep foundry partnerships. In recent years, all nine have made sustained, large-scale bets in AI.

Across arenas, omniscalers are investing in some of the most promising pockets of the global economy. For America to sustain its competitive edge, leaders need to take note.
