Nebius (NBIS) Stock Climbs Amid AI21 Labs Acquisition Talks Following Nvidia’s Exit

TLDRs;

• Nebius’s stock rose following reports that it has restarted acquisition talks with AI21 Labs
• Nvidia had earlier explored a deal but discussions fell through, opening up competition among potential buyers
• AI21 Labs is shifting toward enterprise AI tools as Nebius expands its infrastructure strategy
• Nvidia’s overlapping investments in both firms add complexity to the potential transaction

(SeaPRwire) –   Nebius (NBIS) saw its stock price increase after news broke that it’s engaged in fresh acquisition discussions with Israeli artificial intelligence startup AI21 Labs.

This development comes after AI21 Labs’ earlier negotiations with Nvidia collapsed—Nvidia had considered a potential deal but ultimately failed to reach an agreement. The shift has put Nebius at the center of a new bidding scenario in the AI infrastructure space.

According to reports from The Information and Calcalist, the prior Nvidia-led talks valued AI21 Labs between $2 billion and $3 billion, significantly higher than its 2023 valuation of roughly $1.4 billion. With Nvidia stepping away from the process, attention has now turned to Nebius as a strategic alternative buyer.

AI21 Labs’ Strategic Shift Gains Momentum

Founded in 2017, AI21 Labs has increasingly repositioned itself toward enterprise AI tools after winding down its consumer-facing product, Wordtune. The company now focuses on providing language models and productivity solutions tailored to business users, reflecting a broader industry trend toward monetizing enterprise AI.

Co-founder and chairman Amnon Shashua stated in January that the company was actively evaluating strategic options with multiple potential buyers, including Nvidia. The startup currently generates an estimated $50 million in annual revenue and employs around 200 people, making it a mid-sized but strategically positioned AI application firm.

While financial terms of the Nebius discussions have not been disclosed, market participants view the talks as a potential step toward deeper vertical integration between AI infrastructure providers and application-layer developers.

Nebius Expands Its AI Stack Ambitions

Nebius has been steadily building its presence in AI infrastructure, operating compute services and developing internal model capabilities. The company already runs an in-house large language model research unit and offers inference services through its Nebius AI Studio platform, which allows clients to deploy and manage AI models at scale.

Acquiring AI21 Labs would significantly expand Nebius’s reach into the application layer of AI, allowing it to combine infrastructure provisioning with enterprise software capabilities. This mirrors a broader trend in the cloud and AI industry, where infrastructure providers increasingly seek proprietary or semi-proprietary AI models to strengthen customer retention and pricing power.

The strategic rationale is also supported by demand signals from large enterprise clients. Nebius has previously referenced major commercial relationships, including contracts and prepayments tied to tech giants like Microsoft and Meta, underscoring strong demand for AI compute and deployment services.

Nvidia’s Ties Complicate the Deal Landscape

A key layer of complexity in the potential transaction is Nvidia’s overlapping investment exposure. The chipmaker has invested in both Nebius and AI21 Labs, including participating in AI21’s Series C funding round alongside other major tech investors. Nvidia also committed substantial capital to Nebius through direct investment and share warrants.

These cross-holdings suggest the potential acquisition is not a simple buyer-seller transition but part of a more interconnected AI infrastructure financing ecosystem. Analysts note that such overlapping interests may influence valuation expectations and negotiation dynamics.

Still, despite the structural complexity, the renewed talks highlight ongoing consolidation pressure in the AI sector. As infrastructure providers move up the value chain and application companies seek scale via strategic buyers, deals like the Nebius–AI21 Labs discussions may become increasingly common.
