The AI data center buildout is no longer just a technology story - it's a public finance story. A June 9, 2026, panel at the National Association of Securities Professionals' 37th Annual Financial Services Conference in Detroit gathered leaders from public power, investment banking, economic development, and local government to examine how the next wave of infrastructure investment will shape tax bases, utility planning, and municipal financing. The discussion made one thing clear: the communities and public finance professionals who treat this infrastructure cycle as a capital markets opportunity will define who benefits.
The session, "The AI Data Center Supercycle: Capital Markets, Incentives, Power & Water: How Wall Street and Main Street Can Win Together," featured Adam Barsky, Executive Vice President and CFO of the New York Power Authority; Harry Singh, Managing Director at Goldman Sachs; Neal Richardson, Director of Housing and Economic Development Advisory Consulting at Baker Tilly; and Joseph Deason, Executive Director of the Madison County Economic Development Authority in Mississippi. Moderator Dr. Dell Gines, senior advisor and former Chief Innovation Officer at the International Economic Development Council, kept the focus on practical realities, not just the scale of private investment.
Power is the defining constraint
Singh put the capital opportunity in context: the telecom boom of the late 1990s generated roughly $300 billion in capital formation. AI-related data center investment could approach $5 trillion. U.S. installed data center capacity, now around 40 gigawatts, is projected to more than double by decade's end. Yet access to capital isn't the bottleneck - it's access to power.
Barsky described the mismatch between development timelines and grid realities. A hyperscale facility needing hundreds of megawatts cannot always wait years for traditional interconnection and transmission upgrades. Developers are turning to behind-the-meter generation, fuel cells, natural gas, and phased power solutions to bridge the gap. Over the longer term, small modular reactors could offer reliable, emissions-free baseload, but commercial deployment remains years away.
For issuers and utilities, the equation is straightforward. Communities that deliver reliable, affordable power at speed will attract investment. Those that can't will be sidelined. Energy infrastructure has become economic infrastructure, and it is now a primary determinant of growth and credit strength.
Traditional economic development metrics are under strain
Hyperscale data centers are capital-intensive but light on permanent jobs relative to the investment. That creates a political problem when local officials must justify tax incentives and zoning approvals to residents. Richardson pointed out that communities are often asked to commit significant support for projects whose direct employment numbers don't tell the full story.
Deason offered Madison County as a counterexample. The county has announced more than $21 billion in private investment commitments and approximately 1,700 jobs over the past two and a half years. The real payoff, he said, is the expanded tax base that supports schools, roads, water and wastewater systems, and broadband - assets that strengthen long-term competitiveness.
That distinction matters for public finance professionals. A data center's value isn't captured by headcount alone. It shows up in tax base growth, utility system improvements, workforce development, local procurement, and the fiscal capacity to fund public infrastructure.
Water is becoming a site selection factor
While power remains the primary gatekeeper, water consumption is moving to the forefront of permitting and local opposition. Deason described how hyperscale operators in Madison County use reclaimed water - treated residential and industrial wastewater purified through ultrafiltration and reverse osmosis - instead of drawing exclusively on potable supplies.
Projects that expand reclaimed water capacity and modernize wastewater treatment can align economic development with resource management. For bond market participants, water availability is no longer a peripheral concern. It directly affects permitting risk, infrastructure investment requirements, and long-term credit analysis.
The capital stack goes well beyond the hyperscaler
Data center development now involves a sophisticated ecosystem of merchant developers, infrastructure funds, and institutional capital. Hyperscale operators often sign long-term service-level agreements with rigorous performance standards and financial remedies, creating predictable revenue streams that support project finance structures and, increasingly, asset-backed securitizations.
Barsky highlighted a tool with direct relevance to the municipal market: prepaid power transactions. NYPA recently completed nearly $1 billion of prepaid solar deals using tax-exempt bonds to prepay for power. The structure reduced the effective cost of energy by an estimated 7% to 10%, with Google as one of the purchasers. The same principle applies to transmission upgrades, substations, water facilities, and roads - public assets that can be financed against the durable tax and utility revenue hyperscale development generates.
Deason confirmed that Madison County is preparing a significant public infrastructure financing backed in part by the expanded tax base from hyperscale investment. For issuers, advisors, and investors, understanding the capital stack behind these projects will be as important as understanding the facilities themselves.
Community benefit is not an afterthought
Public trust is the political counterpart to the power constraint. Data center proposals have met with moratoriums, litigation, and opposition in several markets, often because residents aren't sure who will bear the costs and who will see the benefits. Richardson argued that the problem is structural: communities are frequently asked to evaluate complex deals after key decisions have been made, leaving officials to explain them under pressure.
Communities that establish clear frameworks early - addressing workforce development, local contracting, revenue sharing, environmental performance, and accountability - are better positioned to negotiate durable agreements. Deason said local support in Madison County grew once residents connected the investment to tangible improvements: expanded school funding, better roads, upgraded water systems, and wider broadband access.
Early engagement reduces project risk, shortens approval timelines, and builds the political capital needed to sustain long-term development.
Why this matters for finance professionals
Public finance attorneys, municipal advisors, investment bankers, and issuers should start treating data center projects as infrastructure transactions, not just economic development deals. The critical questions center on grid capacity, water resources, cost allocation, revenue streams for debt service, and the enforceability of incentive agreements. Municipal tools - prepaid power structures, utility revenue bonds, tax increment financing, and infrastructure financings backed by a growing tax base - can turn private investment into lasting public assets. The AI data center expansion is already underway. The communities and finance professionals who engage early and negotiate from a position of clarity will shape where the next infrastructure cycle creates value, and who benefits from it.
