Spending by major tech firms on artificial intelligence (AI) infrastructure has surpassed investment in oil and natural gas production.
The shift comes as these companies drive an unprecedented surge in data centre funding in 2025, according to the International Energy Agency.
AI Becomes a Bigger Capital Story Than Oil and Gas
Combined capital expenditure of five tech firms topped $400 billion last year. Moreover, the IEA estimates that this could climb another 75% in 2026, signaling that AI infrastructure has become a dominant force in global capital flows.

On the demand side, the expansion appears equally strong. Major AI model providers reported a 3x increase in active users and a 5x surge in revenue over the past year, metrics that help explain the investor positioning around the sector.
However, the scale of investment is beginning to outpace what companies can fund internally. Data centre development has grown too capital-intensive to rely solely on corporate balance sheets, making external financing from capital markets increasingly essential.
Debt markets are already reflecting this shift. AI-related debt has climbed to $1.4 trillion, making it the largest segment within US investment-grade credit markets.
Nonetheless, this reliance means that the pace of data centre expansion and the corresponding rise in energy consumption are expected to remain highly sensitive to market sentiment.
Investor expectations around returns on AI infrastructure, alongside broader macroeconomic and financing conditions, will likely determine how quickly the sector continues to scale.
“Understanding the energy implications of AI therefore, also means following closely the technology’s economic trajectory,” the IEA added.
The influence of AI is also becoming more pronounced in equities. BeInCrypto recently reported that AI-linked companies now account for a record 45% of the S&P 500’s total market capitalization.
Together, the capex surge, debt market footprint, and equity concentration suggest AI has become not just a technology story but a defining force in global capital allocation.
