Legora secured $50 million in a Series D extension led by Nvidia's venture arm NVentures, bringing the Swedish AI legal platform's total Series D funding to $600 million.

The extension maintains Legora's $5.5 billion valuation from the initial Series D close in March. Atlassian, Adams Street Partners, and Insight Partners also participated in the extension round.

The valuation represents a significant jump from the $1.8 billion Legora achieved in October when it raised a $150 million Series C. The company has now raised $866 million total since its 2023 founding by Max Junestrand, Sigge Labor, and August Erséus.

Nvidia's AI investment spree

Nvidia has backed over three dozen companies in 2026, according to Crunchbase data. The chip giant holds stakes in several high-value AI companies including OpenAI, Databricks, xAI, and Scale AI.

The investment reflects Nvidia's broader strategy of backing AI applications across industries, alongside power-generation investments to support energy-intensive AI infrastructure.

Legal tech funding reached a record $4.08 billion in 2025, up 77.4% from $2.3 billion in 2024. The sector has already raised over $1.3 billion in 2026.

Other major legal tech raises include Harvey raising over $1 billion across four rounds in 2025, and Filevine closing $400 million in two previously undisclosed rounds.

"AI's potential to automate legal work has driven unprecedented investor interest in the sector," said one industry analyst.

Legora competes in the AI-powered legal research and drafting market alongside companies like Harvey and Spellbook. The company plans to use the funding to expand its AI capabilities and grow its enterprise client base across Europe and North America.
