That is a 36% year‑on‑year increase from 2025, making this one of the fastest capital expenditure (CapEx) booms in modern corporate history. 

So, let’s discuss. Is this exceptional AI CapEx surge cycle driving productivity in the economy, or are we inflating another technological asset bubble?

The AI CapEx Scale: What’s Happening Now

Across the largest tech firms, the hyperscalers and cloud giants, capital spending is now structural. Amazon, Google, Meta and Microsoft are expected to put hundreds of billions into new infrastructure in 2026, much of it dedicated to specialised computing clusters, advanced networking and data centre capacity. 

The focal point of this spending is not mere servers or office upgrades. It’s data centres built specifically for high‑power compute workloads, facilities optimised for parallel processing at scale. 

These require specialised hardware like GPUs and high‑bandwidth memory, and they draw massive amounts of energy. 

One recent example shows just how strategic these moves have become. Nebius Group signed a multi‑year deal with Meta Platforms worth up to $27 billion to supply dedicated AI computing capacity by 2027, a contract driven by extreme demand and limited supply for high‑performance computing systems. 

Productivity: What the Investment Could Bring

No doubt that enhanced computing capacity enables economic value. Faster processing, more reliable inference workloads, and greater cloud availability can drive:

• Higher labour productivity by automating routine tasks.
• Faster research and development cycles in sectors from healthcare to manufacturing.
• Lower costs for compute‑intensive services, once infrastructure matures and utilisation improves.

For context, the semiconductor industry, a cornerstone of this infrastructure build‑out, is forecast to approach nearly $1 trillion in sales in 2026, with AI‑specific chips maintaining strong annual growth. 

From a macro perspective, such CapEx adds directly to aggregate demand and GDP in the short term. Data centre construction, advanced chip manufacturing, and supporting supply chains all contribute to economic activity that wouldn’t exist without this cycle. 

Bubble Territory: Where the Risks Begin

But there are strong arguments that we are edging into asset inflation rather than productive investment.

First, the pace of spending vastly outstrips current revenue realisation in the economy. Many of these specialised facilities operate at negative operating margins early in their life, requiring ongoing funding before they generate sustainable returns.

Second, a lot of the valuations attached to tech infrastructure assets incorporate lofty future earnings expectations. If those earnings don’t materialise, because adoption slows or competition increases, we could face rapid repricing. 

We’ve already seen some tension in the market, with certain historic investment commitments being scaled back. 

Third, hyperscalers are relying more on external financing even as their own cash flows get tighter. That’s a classic hallmark of an investment boom that may not be fully backed by near‑term productive returns. 

Semiconductors and Data Centres: The New “Oil”?

The analogy of compute as “the new oil” captures two truths:

1. Dependency: Modern AI workloads require massive compute capacity, just as 20th‑century industry relied on petroleum.
2. Infrastructure bottlenecks: Scaling compute, even with unlimited capital, is limited by semiconductor supply, power delivery, and cooling technology.

Already, suppliers like TSMC have posted strong revenue outlooks, showing reliance on advanced chips across the industry.

In parallel, smaller specialist data centre operators, such as CoreWeave, have expanded at a rapid clip. CoreWeave now operates dozens of facilities globally and has become a major supplier for bespoke compute capacity. 

But then, this infrastructure is expensive and energy‑intensive. Many facilities find it hard to break even without long‑term contracts or guaranteed utilisation.

Investment Implications: Winners and Fragilities

From an investment standpoint, certain firms appear ready to benefit if demand holds:

• Nvidia is at the centre of the compute supply chain. Its recent San Jose GTC 2026 forecast shows at least $1 trillion in chip revenue by 2027, driven by demand for next‑generation chips at scale. 
• Other chip designers and foundries stand to gain from backlogged orders and long production lead‑times.
• Data centre REITs and infrastructure funds may see longer‑term cash returns as contracts mature.

On the risk side, overcapacity, falling prices for older hardware, and slower adoption outside of hyperscale use cases are still substantive challenges.

So, Growth Engine or Asset Bubble?

Standing here in March 2026, we see both sides.

On the productivity side, this spending wave is building infrastructure that will underpin major advances in how industries operate. It’s tangible investment in capacity, not just speculation in intangible assets.

On the asset inflation side, the pace and scale of spending go beyond today’s revenue reality. Markets have priced future growth aggressively, which increases the risk of repricing if adoption deviates from expectations.

Now, are we financing a foundation for long‑term productivity, or are we inflating the price of future earnings prematurely?

Speaking at the Nigeria Economic Summit Group (NESG) 2026 Macroeconomic Outlook launch in Lagos, Edun said the high execution rate reflected enhanced transparency, improved public financial management, and a deliberate policy focus on completing ongoing infrastructure projects rather than leaving them unfinished.

“In aggregate, capital expenditure in 2024 reached 85 per cent performance,” Edun said, noting that the National Assembly extended the implementation period of the 2024 budget, allowing critical road, energy, housing, and social infrastructure projects to be seen through to advanced stages.

The minister emphasised that while capital spending in 2025 is expected to be lower as part of a consolidation strategy amid fiscal constraints, statutory obligations including foreign and domestic debt servicing and salary payments were fully met, reflecting prudent management of limited resources.

Edun described the performance as part of a broader agenda to position Nigeria as a competitive economy regionally and globally, stressing the importance of sustained capital investment to lower the cost of capital, improve electricity supply, expand mortgage financing, and accelerate infrastructure development.

The high execution rate comes as the government projects economic growth of about 4.68 per cent in 2026, aligned with medium-term goals of achieving seven per cent annual growth and building a $1-trillion economy by the end of the decade.

IMF Urges Continued Reform

At the same event, the International Monetary Fund (IMF) cautioned against policy reversals that could undermine hard-won macroeconomic gains.

Dr Christian Ebeke, IMF country representative, highlighted ongoing risks such as persistent double-digit inflation and warned that government intervention in price and volume controls could weaken confidence and fiscal stability.

Banking Sector’s Role in Growth

Dr Muhammad Abdullahi, Central Bank of Nigeria’s (CBN) deputy governor for Economic Policy, said the banking sector’s recapitalisation programme aims to create a more resilient financial system capable of supporting Nigeria’s ambition to scale its economy and deliver productive credit to small and medium-sized enterprises (SMEs) and other growth-critical sectors.

Business and Investment Implications

For the business community and investors, the reported capital expenditure execution demonstrates several positive signals:

• Fiscal discipline and budget credibility: High execution suggests the government is following through on planned projects, reducing the risk of abandoned investments.
• Infrastructure delivery: Greater capital deployment may ease business bottlenecks, particularly in power, transportation, and housing sectors.
• Investor confidence: Combined with projected growth and structural reforms, the emphasis on completing priority projects may enhance Nigeria’s attractiveness to domestic and foreign capital.

However, some economists have raised questions about the tangible economic impact of the capital spending, pointing to delays in fund disbursement and the pace at which project benefits reach the wider economy.

Still, government officials maintain that the focus on execution and fiscal reforms lays the groundwork for more inclusive and sustainable growth, with the 2026 budget branded as one of consolidation, renewed resilience and shared prosperity.

As Nigeria navigates global headwinds and domestic priorities, the ability to sustain strong capital spending outcomes alongside macroeconomic stability will remain central to achieving long-term competitiveness and economic transformation.

This is the largest private investment ever recorded in the state, revealing an escalation in the global need for computing power.

The facility, known as MACROHARDRR, will span about 800,000 square feet and is scheduled to begin operations in February 2026. Governor Tate Reeves confirmed the investment, describing it as a big moment for Mississippi’s economy and its focus on high-end digital infrastructure.

xAI is scaling fast, and Southaven is important to that plan. The site will expand the company’s Colossus supercomputer cluster to almost 2 gigawatts of compute power, placing it in the same league as hyperscale systems operated by Google, Microsoft and Amazon.

The data centre is being developed from a former GXO logistics warehouse and sits close to xAI’s newly acquired power plant site in Southaven, as well as its existing data centre operations in Memphis, Tennessee. 

Memphis already hosts Colossus, which the company has described as the largest supercomputer cluster in the world. The Southaven build effectively extends that footprint across state lines.

Governor Reeves spoke about the scale of the deal, calling it “the largest economic development project in Mississippi’s history.” State officials say the investment will create hundreds of permanent jobs in DeSoto County and deliver long-term tax revenue to support education, healthcare and public safety.

Musk first disclosed the purchase of MACROHARDRR on December 30, noting that it would lift xAI’s total compute capacity to 2GW, though he did not reveal the location or cost at the time. Those details now underline how capital-heavy the push for advanced computing has become.

Demand for data centres surged last year as companies rushed to secure the hardware and power needed to train increasingly complex models.

Bloomberg reported that xAI spent $7.8 billion in cash in the first nine months of 2025 alone, a reminder that firms in this space burn through capital at an exceptional pace.

Globally, investment is growing. Industry forecasts put hyperscaler capital expenditure above $600 billion in 2026, up 36% from the previous year, with around three-quarters of that spending tied directly to advanced computing infrastructure. 

More than 770 future hyperscale facilities are already in the pipeline, and single campuses are now measured in gigawatts rather than megawatts.

Against that backdrop, the Mississippi Data Centre places xAI among the world’s biggest infrastructure builders.
