Private Infrastructure Investing 101 feat. Billionaire Founder / CEO: Mike Dorrell of Stonepeak

In this Infrastructure 101 episode, we sit down with Mike Dorrell, co-founder, chairman, and CEO of Stonepeak, to unpack how infrastructure investing evolved from a niche corner of finance into one of the most important asset classes shaping the global economy. We walk through the origins of modern infrastructure investing --- from Macquarie’s early toll road and airport deals in Australia to the rise of private capital stepping in where governments once dominated --- and explain why infrastructure sits at the intersection of private equity, private credit, and project finance. Along the way, we break down what makes these assets unique: high barriers to entry, essential services, regulated cash flows, and long-duration returns.

The conversation digs into the technical mechanics behind infrastructure deals, including project finance structures, equity versus credit exposure, the role of regulation and tax policy, and why governments are both critical partners and key sources of risk. We explore how infrastructure investors analyze energy markets, power pricing, traffic patterns, and permitting risk, and why changes in “the rules of the road” can make or break long-term investments. From municipal bonds to privatized airports, toll roads, utilities, and power plants, this episode connects the financial structures to the real-world systems people rely on every day.

We also tackle the biggest theme driving headlines today: the AI data center boom. Mike explains why AI is accelerating massive investment across digital infrastructure and energy, what it means for power grids and electricity prices, and how investors distinguish between contracted, de-risked data centers and far more speculative builds. Woven throughout is Mike’s personal story --- from growing up in rural Australia to helping build a global infrastructure platform --- and a candid discussion of what it takes to build durable businesses, invest through cycles, and think long term about both capital and legacy.
