Together AI taps Rumble for Nvidia Blackwell GPU capacity - Data Center Dynamics

Together AI has entered a multi-year cloud capacity agreement with Rumble Inc., an AI compute provider, to secure Nvidia HGX B300 systems for dedicated cloud capacity. While the financial details rema... Read original →

The Together AI–Rumble deal is a geopolitical hedge against hyperscaler dominance, exploiting the 'sovereign AI' policy window in the U.S. and EU. By deploying HGX B300 systems via Northern Data’s infrastructure, Rumble bypasses traditional cloud gatekeepers while triggering downstream demand for advanced liquid cooling, high-speed interconnects, and CoWoS packaging—benefiting TSMC and Marvell. However, if the U.S. Bureau of Industry and Security extends A100/H100-style export controls to Blackwell, Rumble’s European data centers could become the only compliant conduit, sharply increasing its leverage. In response, CoreWeave may accelerate its IPO to scale capacity, while Oracle could undercut with tailored OCI deals for cash-strapped startups. Over the next 18 months, non-traditional cloud providers will capture over 30% of new AI compute supply—but survival will hinge on capital access and geopolitical licensing, especially as NVIDIA’s Rubin architecture widens the performance chasm.
