## Sovereign or Not?
The 2026 Hyperscaler Buyer’s Guide explores data sovereignty in cloud computing.
## Research Background
Amit Eyal Govrin, lead analyst for sovereign AI at theCUBE Research, started researching sovereignty concerns four years ago.
## Kubiya Experience
Kubiya deployed agentic systems in enterprise environments as early as September 2023, creating dependency concerns.
## Buyer Concerns
Enterprises worried about losing control of their AI transformation through vendor dependency on hyperscalers.
## 5 Pillars of Sovereignty
The framework assesses hyperscalers on control over operational, technological, legal, financial, and data pillars.
## CLOUD Act Clawback
U.S. government can access data from any American cloud regardless of location, creating legal conflicts for non-U.S. companies.
## Hyperscaler Responses
AWS and Microsoft admitted they cannot guarantee data sovereignty for non-U.S. companies under the CLOUD Act.
## Solutions Offered
Buyers can self-host data or use local partners to mitigate U.S. CLOUD Act risks, but no perfect solutions exist.
## Data Portability Costs
Moving data out of hyperscalers costs $8,400 with one vendor versus $54,000 to $79,000 with others.
## Latin America Blind Spot
São Paulo is the only city where all seven hyperscalers are present, but none meet Brazil’s data requirements.
## European Sovereignty Law
European regulations don’t reach the top level of sovereignty, and costs to leave hyperscalers are unclear.
## No Off Switch Test
None of the hyperscalers have tested the off switch for their systems, with only one lasting several hours.
## Next Steps
TheCUBE Research will release more guides on neoclouds, OEMs, telcos, and specialized sovereign initiatives.
## Sovereignty Index
The report scores seven hyperscalers across five regions on 17 tests and a legal ladder.
## Buyer Data
The guide includes on-the-record answers from hyperscalers and surveys of actual buyers.
## Key takeaway

Hyperscalers cannot resolve U.S. CLOUD Act data access issues for non-U.S. companies, forcing buyers to choose between self-hosting or local partners.
