NEW YORK — BlackRock Inc.'s $12.55 billion bond offering, structured to finance a Meta Platforms Inc. data center, rallied in early trading Monday after strong investor demand absorbed the supply at initial pricing.

The issuance reflects growing institutional appetite for fixed-income exposure to AI infrastructure. The rally—bonds trading up from their offering price, compressing yields for secondary buyers—signals that the market priced the specialized collateral conservatively and then corrected.

Meta Platforms continues to expand its global data center footprint to support AI model training and inference workloads. At $12.55 billion, the offering ranks among the largest single infrastructure financings tied directly to AI compute capacity.

The early trading performance indicates investors judged the risk premium adequate given the income stream and Meta's credit profile. Yield compression in secondary trading did not deter buyers, pointing to durable demand rather than a one-session technical squeeze.

BlackRock, as a leading asset manager, frequently structures complex debt products for institutional clients. This offering channels capital directly into the digital infrastructure underpinning the AI economy.

Successful execution at this scale sets a pricing reference for future AI-focused infrastructure debt, establishing how large compute buildouts can be financed against long-duration institutional capital.
