Goldman brings Alphabet into prepaid energy market for AI growth

Goldman Sachs has pushed Alphabet into a corner of municipal finance that is suddenly looking much bigger than the old prepaid-gas trade. After arranging Alphabet’s record $85 billion equity raise, Goldman helped structure a roughly $1 billion California prepaid energy transaction that tied the AI giant’s growth plans to long-term electricity supply, not just chips, servers, or model training.

The deal matters because it shows where the bottlenecks in AI are moving. As hyperscalers race to build data centers and lock in power, Goldman is helping turn access to electricity into something that can be financed, priced, and sold like a capital-markets product. In this case, Alphabet was the funding recipient in a transaction issued by the California Community Choice Financing Authority, with Goldman underwriting and arranging the bonds.

That is a notable expansion for a structure that has usually lived in the muni market’s back room. Prepaid energy bonds are tax-exempt municipal debt used to fund the upfront purchase of long-term natural gas or electricity supply, often at a fixed discounted price over decades. CCCFA says it was established in 2021 to lower power costs for member community choice aggregators through pre-payment structures, and it describes these transactions as involving an issuer, an energy recipient, and a supplier, with energy delivered over about 30 years.

Investor appetite was strong. Bond-market reporting said the largest tranche priced at a spread of 95 basis points, a sign that traders were willing to lean into a structure that has gone from niche to strategic. Market sources say prepaid municipal bonds first emerged in the 1990s, and industry estimates put the broader market at more than $80 billion in prepaid natural-gas supply. Goldman has said gas prepay bonds surpassed $31 billion in 2025, a record year helped by lower borrowing costs and rising energy prices.

For Goldman, the personnel behind the business matter almost as much as the product itself. Joseph Natoli, who has spent more than 15 years on municipal and not-for-profit financings, co-heads Goldman’s Public Sector & Infrastructure Group’s West Coast and Energy subsectors and has focused on prepay deals at the firm. His visibility in the segment underscores that this is not a side project. JPMorgan Chase has already hired Goldman banker May Xing to expand its own prepay energy business, a sign that rivals see the same opening.

The California angle adds another layer. CCCFA’s clean-energy financing programs have already been used for long-term renewable purchases, including a June 18, 2025 transaction of more than $1 billion that MCE said would finance 775,000 megawatt-hours annually and save customers about $65 million over 10 years. Alphabet’s entry suggests the same structure can now be adapted for the power needs of AI infrastructure, which is quickly becoming one of the biggest claims on new electricity supply.

For Goldman bankers, that means the fight over AI is no longer only about underwriting equity or financing data centers. It is also about who gets paid to solve the physical problem underneath the boom: enough power, on terms large tech buyers can live with, and fast enough to matter.
