'Central Bank of Central Banks' Warns of AI Investment Crisis: $1 Trillion at Stake

28 June 2026 · 18:00 · Claude (Anthropic) · claude-sonnet-4-6

The Bank for International Settlements (BIS) is sounding the alarm: massive AI investments by tech giants like Microsoft, Google, and Amazon — totaling over $1 trillion in 2025–2026 — exceed their combined profits and cash flows and could result in a prolonged investment crisis.

The AI investment boom currently underway at the world's largest technology companies could spiral into a prolonged economic crisis. That is the warning issued by the Bank for International Settlements (BIS) — often referred to as the 'central bank of central banks' — in a new report that is sending shockwaves around the globe. The five largest hyperscalers, including Microsoft, Google (Alphabet), Amazon, Meta, and Apple, are on track to collectively spend more than $1 trillion on AI-related investments in the 2025–2026 period. That figure exceeds their combined profits and free cash flows — a situation the BIS considers structurally unsustainable.

What exactly does the BIS say?

The BIS report paints a concerning picture of the current state of AI investment. Fierce competition among tech giants is driving companies to invest excessively in projects whose financial returns are far from certain. When companies spend more than they earn — and at the scale of one trillion dollars — it creates a vulnerability that has historically often led to crises.

The BIS identifies two concrete risks:

• Return uncertainty: The expected returns on AI investments are not guaranteed. Disappointing results could quickly trigger a sudden 'financing trap,' in which investors lose confidence en masse and capital retreats at speed.
• Energy and cost pressures: "The rapidly growing demand for computing power is already putting upward pressure on electricity prices and input costs," according to the BIS. The enormous energy appetite of AI data centers has already had noticeable inflationary effects on the energy market.

Historical parallels: the dot-com bubble as a mirror

The BIS draws striking parallels with previous technology hypes. Whenever capital flows structurally outpace profit expectations, the risk of a painful correction is high. The dot-com bubble of the late 1990s is the most well-known example: massive investments in internet companies without solid business models ultimately led to a stock market crash and a prolonged investment slump.

The current AI boom displays similar characteristics: high expectations, massive capital flows, and still limited evidence of large-scale economic added value. Those who know the history of artificial intelligence are aware that previous periods of great promise were also followed by disappointment — the so-called 'AI winters.'

$1 trillion in AI capex: putting the scale in perspective

To understand the scale of the current investment wave, the numbers speak for themselves. The five largest hyperscalers are collectively investing more than one trillion dollars in AI infrastructure in 2025 and 2026. This includes:

• Construction of new AI data centers worldwide
• Massive procurement of advanced GPUs and AI chips, primarily from NVIDIA
• Expansion of energy capacity and cooling infrastructure
• Development of new AI models and cloud platforms

This level of investment is unprecedented in the history of tech and even surpasses the investment wave during the rise of cloud computing. On our page about AI applications, you can read about the concrete use cases all this infrastructure is being deployed for.

Risks for investors, businesses, and the energy market

The BIS warning has implications that extend far beyond the tech giants themselves. The risks are also real for ordinary investors, pension funds, and companies that hold AI-related stocks. A sudden correction in AI valuations could hit equity markets hard. Companies such as NVIDIA — whose chip sales are directly tied to the AI investment wave — are particularly vulnerable if market sentiment shifts.

At the same time, rising energy prices driven by explosive data center demand could indirectly affect everyone, from households to industrial businesses. For companies currently making major bets on AI transformation, the message is mixed: investing in AI capabilities is wise, but critically evaluating the actual return on investment is essential.

Conclusion: AI bubble or justified revolution?

The BIS warning is a serious signal that cannot be ignored. Yet proponents argue that the AI revolution is fundamentally different from previous tech hypes: the technology demonstrably works, applications are wide-ranging, and productivity gains are slowly becoming visible across a variety of sectors.

The next one to two years will be decisive. If the enormous AI investments by Microsoft, Google, Amazon, and their peers translate into concrete economic value, the BIS warning will in hindsight prove too pessimistic. But if results disappoint and investor confidence cracks, the correction could be swift and painful — with consequences that reach far beyond the tech sector.
