Bank of America said it will support $250 billion of eligible financing, investment and advisory activity through July 4, 2027 under a Critical Infrastructure Finance Initiative focused on digital infrastructure, energy and power, and core U.S. systems such as transportation, water and critical minerals. The 18-month target is a mobilization commitment rather than a pledge to put $250 billion of the bank's own balance sheet into projects, with progress measured through lending, underwriting, advisory and co-investment activity similar to the methodology used in major bank sustainable-finance goals. The move comes as Wall Street expands infrastructure programs tied to the AI buildout and as power supply becomes a more pressing bottleneck than chip availability. Bank of America analysts this week raised 2026 hyperscaler capital spending estimates to more than $860 billion, up roughly 80% from a year earlier, with a projected path toward $1.2 trillion in 2027, while Goldman Sachs Research projects U.S. data center power demand will rise from 31 gigawatts in 2025 to 66 gigawatts in 2027. Grid connection timelines in major U.S. markets run 24 to 36 months, and Bank of America has highlighted a potential U.S. electricity shortfall of more than 100 gigawatts between 2026 and 2030. The announcement adds to similar programs from rivals including JPMorgan Chase's $1.5 trillion Security and Resiliency Initiative and Morgan Stanley's $1.5 trillion Innovation Infrastructure Initiative, while differing from Nvidia's recently announced $500 billion GPU-backed financing coalition by explicitly targeting the physical systems needed to support AI deployment beyond computing hardware. Bank executives said the effort will be led by its Global Capital Solutions and Global Infrastructure & Sustainable Finance teams across all eight lines of business and is intended to help address national infrastructure needs while generating commercial returns on market terms.
