Who it is priced against
Closelooknet's peer group does not yet cover this name. The market sometimes places it alongside other post-quantum cryptography firms, such as Quantinuum, when discussing encryption built for a future with quantum computers.
Why Closelooknet tracks it
Arqit holds no index seat in the diary and carries no Closelooknet score yet, so that read is still being built. It has not appeared in our quotes or editions to date.
