Nyobolt hits £1bn on Symbotic-led Series C
UK Startups and InnovationBackground
CBMM is a Brazilian niobium producer whose material is central to Nyobolt's anode chemistry.
CBMM was one of four co-investors in Nyobolt's Series C, announced 6 May 2026. Symbotic, the Nasdaq-listed AI robotics company whose warehouse automation systems run for Walmart, led the £44m round; IQ Capital, Latitude and Scania Invest also participated. The raise valued the Cambridge University spinout, founded in 2019, at $1bn. Nyobolt's anode materials, which draw on niobium, enable a 0-80% charge in under five minutes at twenty times the energy density of supercapacitors, with revenue reported to have grown five times year-on-year.
For CBMM, the stake is grounded in its own product: niobium already sits inside Nyobolt's anode chemistry, giving the investment a direct commercial link rather than a purely financial one.
