Municipal bonds are often linked to schools and toll roads. A small share of new issuance is now tied to the power and water systems behind AI data centers.¹
For founders, executives, and business owners with high incomes, taxes can shape how much investment income is actually kept. We often see clients compare pre-tax yield first and after-tax income second.
Here is what BlackRock's September 2026 research outlines:
▪️ Municipal issuers may finance power, grid, water, and wastewater systems that support data centers¹
▪️ AI-related municipal issuance may reach up to $11 billion in 2026, which is less than 2% of expected annual municipal issuance¹
▪️ Most capital for AI development is expected to come from outside the tax-exempt market¹
▪️ Credit outcomes depend on who pays, contract protections, and execution¹
Interest from many municipal bonds is exempt from federal income tax, and in some cases state tax, depending on where the investor lives and where the bond is issued. Whether that matters depends on the investor's full tax picture.
There are pros and cons. Tax-exempt income may improve after-tax cash flow. Municipal bonds also carry credit risk and interest rate risk, and the research notes that long-term agreements reserved for a single private user can raise tax-treatment questions.¹
Every decision is made custom to the individual, their portfolio, and current market and world conditions. We help executives and business owners work through these decisions daily. Having a trusted person to walk through the details can change the narrative around why it may or may not make sense to act, and over time that can shape the long-term trajectory of short-term decisions.
