NVIDIA’s Suno Investor Fights Music Labels Over Court Testimony

NVIDIA’s venture arm wants out of a courtroom showdown over what it knew before investing in Suno. NVentures has asked a federal judge to block Universal Music Group and Sony’s demand for sworn testimony in their copyright case against the AI music company.

Eminem‘s publisher, Eight Mile Style, has separately demanded roughly $41 million from Suno over alleged copying. That complaint covers 269 compositions, including “Lose Yourself” and “Stan,” and does not name the rapper as a plaintiff.

In its November 10 California court motion, NVentures says it already supplied 6,324 documents totaling 28,194 pages. The firm argues that the labels should question Suno about its training data and operations instead of requiring an investor to explain them.

“It holds no board, observer, or advisory position with Suno,” NVentures’ lawyers wrote in the motion.

The companies are still contesting 10 subjects for questioning after negotiations narrowed the original subpoena. Those include investment research, licensing costs and communications about the legal risks attached to Suno’s training data.

NVentures participated in Suno’s November 2025 funding round, after the labels had already sued. It asks the judge to cancel the subpoena or restrict its scope.

That financing brought Suno $250 million at a $2.45 billion valuation, with Menlo leading the round and Hallwood Media, Lightspeed and Matrix also participating. The company subsequently raised more than $400 million in June 2026.

Universal and Sony began their underlying lawsuit in June 2024, accusing Suno of training its technology on recordings without permission. Warner Music Group initially joined them but settled in November 2025 and entered a licensing agreement.

The investor fight also reaches beyond NVIDIA. Lightspeed Venture Partners, which holds a Suno board seat, has challenged a separate subpoena, while a judge allowed the labels to question former Menlo Ventures principal C.C. Gong about a deleted social-media post.

Universal has another relationship with NVIDIA outside the litigation. The companies announced an AI collaboration in January involving the chipmaker’s Music Flamingo model, with safeguards for artists and copyright among its stated aims.

The labels’ responses to the two motions filed by NVentures and parent company NVIDIA are due November 24.
