AI Infrastructure Funding: $100B+ Borrowed in 2025 | Refinitiv Data

NEW YORK, December 26, 2025 — Artificial intelligence infrastructure companies borrowed more than $100 billion in 2025, but smaller firms hoping to capitalize on the AI boom are facing significantly higher interest rates as investors grow wary of unproven business models.

Investor Caution Slows AI Funding

Debt investors are becoming increasingly selective, demanding higher returns from AI companies seeking capital.

  • AI infrastructure companies collectively borrowed over $100 billion this year.
  • Smaller AI businesses are experiencing increased borrowing costs.
  • Investor skepticism surrounding unproven AI ventures is driving the trend.

The surge in borrowing reflects the intense investment in the foundational technologies powering artificial intelligence, such as data centers and chip manufacturing. However, the landscape is shifting, and the cost of capital is rising, particularly for companies lacking a demonstrated path to profitability. This means that while the big players can still access funds, smaller, innovative AI startups are finding it harder to secure financing on favorable terms.

The Risk Factor: Unproven Models

The increased caution from debt investors stems from a growing concern that many AI businesses are built on hype rather than solid fundamentals. Investors are scrutinizing revenue models and demanding clearer evidence of market demand before committing capital. This heightened scrutiny is leading to a divergence in borrowing rates, with established AI infrastructure companies enjoying relatively low rates while smaller, unproven ventures face steeper costs.

What are investors looking for in AI companies? Investors are prioritizing businesses with clear revenue streams, demonstrable market traction, and a sustainable competitive advantage.

The current environment presents a challenge for AI startups, forcing them to prioritize efficiency and profitability. Companies that can demonstrate a clear value proposition and a viable path to revenue generation will be best positioned to attract investment, even in a more cautious market. Those relying solely on the promise of future AI breakthroughs may find themselves struggling to secure the funding they need to survive.

The Impact on Innovation

The higher cost of capital could potentially stifle innovation in the AI space, as smaller companies with limited resources may be unable to compete with larger, well-funded players. This could lead to a consolidation of the industry, with a few dominant companies controlling the majority of the market. However, it could also force startups to become more resourceful and focused, leading to more sustainable and impactful AI solutions.

Navigating the New Landscape

AI companies seeking funding in the current environment need to be prepared to answer tough questions from investors. A well-defined business plan, a clear understanding of the competitive landscape, and a realistic assessment of market demand are essential. Demonstrating a commitment to financial discipline and a focus on profitability will also be crucial for attracting capital.
