Bull and Kalray team up to co‑develop next‑generation high‑speed networking solutions targeting AI‑era data center demands
Executive summary: Bull and Kalray announced a strategic partnership to develop the next generation of high‑speed networks for the AI era. The deal responds to growing AI‑driven demand for low‑latency, high‑bandwidth interconnects in data centers, potentially accelerating AI infrastructure deployment.
Who is involved: Bull (advanced computing/AI leader) and Kalray (Euronext Growth Paris: ALKAL, hardware/software specialist for HPC and data infrastructure).
Likely next: Joint R&D phases, prototype testing in late 2026, followed by pilot deployments with select customers in early 2027.
On July 28 2026, Bull, a leader in advanced computing and artificial intelligence, announced a strategic partnership with Kalray, a specialist in hardware and software for high‑performance computing, to jointly develop the next generation of high‑speed networks. The collaboration aims to address rising bandwidth and latency requirements driven by AI workloads, combining Bull’s AI expertise with Kalray’s data‑plane processors. No financial terms were disclosed, and the partners said the initiative will focus on research, prototyping and early customer engagements.
What's next — scenarios
