Brookfield Closes $4B First Round for Fourth Infrastructure Debt Fund 

Brookfield has raised more than $4 billion in the first closing of its Brookfield Infrastructure Debt Fund IV (BID IV), a strategy designed to target high-yield debt investments across infrastructure assets and businesses supported by regulated, contracted, or concession-based cash flows. The fund aims to give investors diversified exposure to both infrastructure and private credit, sectors where demand for capital continues to accelerate. 

“Demand for capital to support infrastructure growth is substantial, creating strong opportunities to partner with leading companies and finance their infrastructure businesses,” said Ian Simes, co-head of Brookfield’s infrastructure debt and structured solutions businesses. 

Brookfield has already been deploying significant capital through its infrastructure credit platform, investing more than $4 billion in 2024 alone. Notable recent transactions include a $750 million credit facility to Crusoe to expand its AI-driven “factories” and a $150 million facility to Qair Polska, a renewable energy developer in Poland. 

The firm’s prior infrastructure debt fund, BID III, closed with $6 billion of commitments in 2023, making it at the time the largest private infrastructure debt fund globally. With BID IV, Brookfield is building on that momentum as demand for private financing in infrastructure, energy transition, and digital backbone assets continues to expand. 

As of August 6, 2025, Brookfield’s global credit platform manages approximately $332 billion, spanning infrastructure, renewables, real estate, asset-backed, and corporate credit strategies.
