Rumble announced a $270 million multi-year agreement with Together AI for dedicated GPU cloud capacity, sending RUM shares up as much as 14% in premarket trading.

It’s the largest customer commitment in Rumble’s history.

What the deal actually involves

The agreement, disclosed via an 8-K filing on June 3, 2026, will see Rumble provide Together AI with dedicated GPU cloud capacity powered by NVIDIA’s HGX B300 systems. Those are Blackwell-generation chips designed specifically for the kind of heavy AI workloads that companies like Together AI need to run large language models and other compute-intensive applications.

Together AI, which builds infrastructure for running open-source AI models, gets reliable access to high-performance compute without building its own data centers from scratch. Rumble gets a $270 million revenue commitment.
