The OMAMA – Aggregated view of the Hyperscalers
The post below is a collective view of 5 posts that I wrote on Linked In during my motor biking adventure in Arunachal Pradesh, India in early April 2026. It gives an aggregated picture of the scale of the 5 Hyperscalers.
Post 1 of a 5 part series. INTRODUCTION.
Some rituals deserve to be repeated!
Same time last year, my buddies and I rode Royal Enfield Meteors and Himalayans past glaciers and under vast skies in picturesque Ladakh. This year the road leads us to breathtaking Tawang in Arunachal Pradesh, among snow-capped peaks and alpine lakes.
And just as the mountains have their seasons, so do Markets! Same time last year, markets were rocked by Liberation Day events. This time, it is the slow-burning tensions in the Middle East.
My riding philosophy doubles as my investing mantra – Keep Calm and Carry On!
Over the next 7 days, I will post 4 articles and one best photograph from the road.
What will I write about?
Over the past decade and a half, US equity markets have turned increasingly concentrated in a handful of stocks. Different acronyms have been the flavour of the season at different times – FANG, FAANG and Mag 7.
Today, Nvidia may be the dazzling protagonist of the greatest equity markets story of our time. But the heart of the matter — the engine, the infrastructure, the nervous system — belongs to five hyperscalers: Oracle, Microsoft, Alphabet, Meta and Amazon. The OMAMA.
Over the next 4 articles, I will summarize the aggregate mind numbing scale of OMAMA and well as summarize some simple key takeaways and points to watch out.
Five Companies. One Planet. Too Big to Fail?
Stay Tuned. And Vroom….


Post 2 of a 5 part series. AGGREGATE REVENUES OF OMAMA.
FY 2025 combined Total Revenue of OMAMA = $1.66Tn
At $1.66 trillion, OMAMA’s combined revenues exceed the GDP of all but 15 countries on earth — in other words, this single group of five companies out-earns the entire economy of over 180 nations.
The market expects an average revenue growth rate of 15% over the next 2 years i.e. Revenues of $1.9Tn and $2.2 Tn in 2026 and 2027. The $540 billion in incremental revenue that OMAMA is expected to add over the next two years is larger than the entire GDP of Singapore or Thailand or Bangladesh.
The key component to understand is that out of the $1.66Tn, roughly $350Bn is Cloud related revenue – which basically needs to grow at 25%-40% rates in the short to medium term.
This massive growth in Total Revenues is fundamentally a bet that AI will structurally increase global demand for compute, software, and advertising efficiency, with hyperscalers capturing that through both infrastructure and application-layer monetization.
It is key to understand the AI related revenue drivers for each of the 5 hyperscalers.
– Microsoft’s growth depends both on monetizing AI at the application layer (Copilot and enterprise software) and on capturing the increase in global compute demand through Azure.
– Alphabet’s growth depends on using AI to defend and enhance its core advertising and search economics, while also capturing increase in global compute through Google Cloud.
– Amazon’s growth depends on capturing increasing global compute demand through AWS, while embedding AI across its commerce and logistics ecosystem to drive efficiency and incremental monetization.
– Meta Platforms’ growth depends on using AI to increase user engagement and advertising yield across its platforms, thereby expanding revenue per user.
– Oracle Corporation’s growth depends on serving concentrated, large-scale AI and cloud workloads through its infrastructure offerings, while leveraging its enterprise database and applications footprint to anchor demand, with a more capacity-driven model that is highly sensitive to utilization and customer concentration.
In the next post, we will look at the aggregate mountain of Debt in OMAMA.

Post 3 of a 5 part series. AGGREGATE DEBT OF OMAMA.
Across OMAMA, headline leverage metrics remain superficially benign despite a meaningful step-up in capital expenditures.
Total Debt has more than doubled at these 5 hyperscalers – from ~$200bn in 2023 to ~$300bn in 2025 and ~$420bn in early 2026! That is roughly equal to the entire GDP of South Africa – a country of more than 60 mn people!
Measured against operating cash flow, which has grown from ~$360bn to ~$580bn over the same period, leverage appears modest at ~0.5-0.6x Debt-to-Operating cash flow. On the surface, this suggests ample debt servicing capacity and balance sheet resilience. However, this framing understates the true economic burden.
First, Operating cash flow is not Free cash flow. A substantial portion of OCF must be reinvested into capex to support AI-driven infrastructure buildouts, at least in the next 2-3 years.
Share buybacks and dividends further constrain financial flexibility. (It would be a negative signal if these companies slashed dividends or share buybacks). As a result, the cash truly available for servicing incremental debt is materially lower.
Second, and more importantly, traditional on-balance sheet debt only captures part of the financing picture. Hyperscalers are increasingly funding capacity expansion through long-duration lease commitments—particularly build-to-suit data center arrangements—which function as debt-like obligations but are either underrepresented or entirely absent from current balance sheets.
These lease commitments: Require fixed, multi-year payments, Are often contracted well ahead of asset delivery, Will progressively convert into recognized liabilities over time
Taken together, this creates a growing pool of “forward-deployed leverage”—obligations that are economically real but only partially reflected in reported debt metrics today.
Oracle is the standout risk in the group. With $135Bn of total debt and expected FY 26 Operating cash flow of $28Bn, it is heavily dependent on rapid growth in revenues which in turn is dependent on Open AI’s fortunes.
Interestingly, this is still not the complete picture. In the next post, I will elaborate more on these Leases! Specifically, what you see on the balance sheet in the form of Leases is the tip of the iceberg, with a major amount below the surface of the sea!

Post 4 of a 5 part series. AGGREGATE LEASES OF OMAMA.
Lease accounting governs how companies recognize and disclose leases on their financial statements. The most significant recent change came with IFRS 16 (Internationally) and ASC 842 (US), both of which took effect for most companies in 2019, replacing the old IAS 17 and ASC 840 standards respectively. The core change was the elimination of the “operating lease” off-balance-sheet treatment. Under the new rules, lessees must now recognize virtually all leases on the balance sheet as a right-of-use (ROU) asset and a corresponding lease liability, making previously hidden obligations visible to investors. The practical impact was significant: companies in asset-heavy, lease-intensive industries like retail, airlines, and logistics saw their balance sheets inflate considerably, affecting metrics like debt ratios, EBITDA, and return on assets.
Lease liabilities (on the balance sheet) across OMAMA have risen sharply, from ~$69bn in 2023 to ~$165bn in 2024 and ~$212bn in 2025!
This increase should be viewed alongside the concurrent rise in on-balance sheet debt—from ~$200bn in 2023 to ~$420bn in early 2026!
However, even this combined view remains incomplete!
A much larger pipeline of obligations sits off-balance sheet in the form of leases not yet commenced, which have expanded dramatically—from roughly $100bn in 2023 to an estimated ~$680bn by early 2026! This is the number that will eventually reflect on the liabilities side of the Hyperscalers balance sheet, albeit a discounted to present value number.
These represent contracted, long-duration commitments for future capacity that have not yet been capitalized, but will progressively convert into recognized lease liabilities as underlying assets are delivered.
Once again, this dynamic is most pronounced for Oracle Corporation. Oracle’s on-balance sheet debt is already high at $90 Bn (May 2025) and reported lease liabilities are ~$15bn range, but more importantly, its Lease liabilities for leases not commenced as of Feb 2026 have increased to a whopping $261Bn! Relative to Oracle’s current ~$60bn revenue base (or even taking into account $88Bn expected FY 2027 revenue) and materially lower operating cash flow compared to hyperscaler peers, this implies a much higher ratio of forward, fixed commitments to cash-generating capacity, increasing sensitivity to capacity utilization and execution risk!
In the next and final post, we will examine aggregate capex across OMAMA!

Post 5 of a 5 part series. AGGREGATE CAPEX OF OMAMA.
Capital expenditures across OMAMA have accelerated sharply, rising from ~$150bn in 23 to ~$223bn in 24 and ~$375bn in 25, with projections pointing to a step-up to ~$640bn in 2026.
Until now, this expansion has remained broadly supported by operating cash flow, which increased from ~$360bn in 23 to ~$470bn in 24 and ~$580bn in 25. However, the funding dynamics are getting increasingly difficult. At $700Bn of projected 2026 Operating cash flow, projected capex roughly equals operating cash flow, leaving limited internally generated cash to fund other uses.
But these hyperscalers also need to demonstrate consistent dividends and share buybacks. In 2025, OMAMA returned roughly ~$150bn through dividends and share repurchases. For instance – share repurchases are needed simply to offset the massive dilution from monstrous SBC pay packages. With operating cash flow increasingly committed to infrastructure investment, these distributions—and any incremental flexibility—would need to be funded through existing balance sheet cash or additional external financing.
Once again, Oracle remains a standout risk. Expected FY26 Operating cash flow of $28Bn. But it needs to spend over $50Bn each year in Capex over the next 2-3 years. Post the February bond issuance, cash on hand sits at $38Bn and the Company plans to raise equity of another $20Bn. The numbers make $5Bn of historical dividends somewhat unsustainable!
Across these five articles, one thing should be impossible to miss — the scale of OMAMA is not just large. It is system-defining. We are, for the first time, witnessing the emergence of corporations so large, so interconnected, and so deeply embedded in global digital infrastructure that the language of systemic risk — once reserved for banks — is beginning to feel appropriate. Too Big to Fail is no longer just a Wall Street phrase.
It is little surprise, then, that OpenAI’s CFO Sarah Friar had floated the idea of a federal backstop — essentially a government guarantee — for investments in AI chips and data centres. When a private sector executive starts speaking the language of sovereign guarantees, you know the numbers have entered stratosphere.
And beneath all of this lies a question that the market has not yet fully answered: can AI revenues — consumer and enterprise combined — actually grow fast enough to justify what is already being spent? The capex is real. The returns are still, largely, a promise!
