Celero, a networking‑chip startup building long‑distance links for AI data centers, secured $275 million in funding, valuing the company at over $3 billion.
Celero Communications, a U.S. startup founded by networking veterans, announced on Monday that it has closed a new funding round worth $275 million, pushing its valuation above $3 billion. The capital infusion backs Celero’s core product: a coherent digital signal processor designed to accelerate long‑distance, high‑bandwidth optical links between AI data centers. By reducing latency and power consumption on fiber‑optic connections, the chip aims to make it feasible to stitch together geographically dispersed compute clusters into a single, scalable AI super‑grid.
The raise underscores a growing wave of investment in the “inter‑data‑center” layer of AI infrastructure. As AI models balloon in size and demand ever‑greater compute, operators are looking beyond the confines of a single campus. Faster, more efficient links enable firms to locate servers near cheap power or cooling while still delivering the low‑latency data streams needed for training and inference. Celero’s technology therefore addresses a bottleneck that could limit the next generation of AI workloads and may help alleviate pressure on local power grids—a concern highlighted in recent coverage of community opposition to AI data centers.
Investors have not disclosed the full roster of participants, but earlier rounds were led by Alphabet’s CapitalG, suggesting continued interest from major cloud players. Going forward, the market will watch whether Celero can move from prototype to volume production and secure design wins with hyperscale operators. Success could spur further capital into optical‑AI networking and shape the architecture of future AI compute ecosystems.
