Liquid Cooling for AI Act of 2025

1) The Liquid Cooling for AI Act of 2025 was introduced in the Senate on November 20, 2025, and had a subcommittee hearing on April 15, 2026. It is still in committee, not signed into law. The bill does nothing more than direct the GAO to conduct a technology assessment on liquid cooling for AI compute clusters, based on findings that air cooling is reaching limits and liquid cooling is increasingly necessary for high-density AI workloads. 2) The money trail is zero. This bill authorizes no funding, creates no mandates, directs no procurement, and includes no tax incentives. The actual bill text states only that 'the Comptroller General shall conduct a technology assessment.' There is no appropriation and no spending authorization—this is purely a study. 3) Structural beneficiaries on a long-term horizon are pure-play liquid cooling infrastructure providers. Super Micro Computer ($SMCI) designs and builds liquid-cooled AI servers and data center solutions. Vertiv supplies thermal management systems, including coolant distribution units, pumps, and heat-reuse components. Diversified players like $NVDA and $AMD benefit indirectly as AI compute demand rises, but this bill has no direct effect on their revenue. 4) As of April 30, 2026, $SMCI trades at $26.88, down 7.57% over 7 days but up 18.05% over 30 days. trades at $319.08, down 1.35% over 7 days but up 27.34% over 30 days. These price movements reflect broader AI infrastructure demand and sector volatility, not this bill's passage. 5) The bill has cleared one of several legislative steps: it passed a subcommittee hearing on April 15, 2026. It must clear full committee markup, pass the Senate, pass the House, and be signed into law. No companion bill exists in the House. Passage probability is moderate but timing is uncertain—GAO studies take months to over a year to complete after enactment.
