Solstice Partners With ApexE3, Tensorix to Enter Sovereign AI Finance

Solstice, a Solana-based on-chain credit and treasury management platform, is entering the sovereign artificial intelligence infrastructure finance market.

The company said on June 8 that it had partnered with ApexE3 and Tensorix to expand into sovereign AI infrastructure finance. ApexE3 and Tensorix are sovereign AI infrastructure companies based in the U.K. and Ireland, respectively.

The partnership is focused on supplying capital for AI infrastructure. Because sovereign AI platforms must operate without leaving sensitive data on external systems, they need to build large-scale graphics processing unit, or GPU, infrastructure in-house. Solstice said it plans to use its on-chain financial infrastructure to support that buildout.

That is also the backdrop for Solstice's launch of yield-bearing digital asset aiUSX. The product is designed to improve capital efficiency for AI companies. Companies that allocate cash and other assets to aiUSX can access returns generated from AI infrastructure lending.

Solstice said the structure could improve on the conventional approach of managing idle assets separately from AI infrastructure costs. The company said aiUSX was designed as a liquid asset that can be redeemed when needed. Returns generated through aiUSX can also be used to offset AI inference costs.

Solstice sees aiUSX as a new treasury management tool for AI companies. Chief Executive Officer Van Nadareski said rising inference costs are increasing funding pressure across the sector. aiUSX allows companies to access the AI infrastructure lending market using capital they have already set aside for AI purposes, he said. He added that the market had historically been open only to large institutions and could become a treasury management model for the AI era.

Solstice said it is also reviewing ways to use its native tokens, USX and SLX, across the ApexE3 and Tensorix ecosystems. The company aims to let AI agents use Solstice tokens to pay directly for services such as inference in on-chain environments.

Tim Grant, chairman of ApexE3 and Tensorix, said sovereign AI is a capital-intensive business that requires a partner with expertise in both technology and financial structuring. He said Solstice was the right partner because it offers services that allow institutions to hold AI budgets as productive assets.
