2026 eDiscovery Buyers Report: AI and Deployment Trends

As AI has become an operational priority for legal teams and the industry’s main incumbent is sunsetting its private deployment solution by 2028, buyers are reconsidering where eDiscovery runs and who controls it. We surveyed 200 senior eDiscovery buyers to understand how they're navigating these changes and found they're demanding deployment flexibility to support their AI ambitions.

The AI disruption meets a forced migration

Two pressures now hit every large eDiscovery buyer at once. AI rewires their cost/value equation and their workflows while causing data volumes to explode. Meanwhile, the market’s largest incumbent has forced a deplatforming, putting infrastructure decisions back on the table. The foundation shifts, and the workflows reinvent, so how do you choose what technology to invest in amongst that landscape? We asked. Our most conclusive findings include:

1
Buyers base platform and infrastructure decisions primarily on the technology's perceived ability to accommodate AI as it expands.  
2
Private deployment caseloads keep climbing since buyers see private and hybrid models as the best way to absorb the cost of exploding AI-driven data volumes while keeping their AI models independent.  
3
Market dynamics point toward an exclusively “public cloud-first future,” but nearly half of all matters today already require private cloud or on-premises deployment for data residency or cost reasons.
4
Buyers distrust a single deployment approach: 68% say commercial interest drives their primary vendor's deployment consolidations more than the market’s actual needs.

Say the ability to run their own proprietary or fine-tuned AI models is important to their operations

"The buyers we surveyed have made their position clear: they want AI capability and deployment control, and they see every reason to have both. As AI models evolve and data volumes climb, the organizations that lock themselves into a single vendor's infrastructure will find it increasingly difficult to adapt."
