Yes, but as I said:Seems Cat 8 is a thing.
CAT 8
Category 8 is the official successor to Cat6A cabling. It is officially recognized by the IEEE and EIA and parts and pieces are standardized across manufacturers. The primary benefit of Cat8 cabling is faster throughput over short distances: 40 Gbps up to 78’ and 25 Gbps up to 100’. From 100’ to 328’, Cat8 provides the same 10Gbps throughput as Cat6A cabling.
Due to these distance limitations, the best use case for Cat8 would be inside a data center to connect network equipment to each other. It would not be cost-effective to use Cat8 for an office build out as the distance would quickly decrease the speed throughput to that of Cat6A, which is cheaper to procure and install for the same performance.
Rainmaker said:Cat8 isn't a real thing, certainly for home deployment.

'Cat 7' and 'Cat 8' on certain shopping sites are likely copper coated aluminium junk that went overly heavy on the marketing (because 8 is bigger than 6 and 5, amirite?).
Show me a 'cat 8' cable the average home user buys because '8 is better than 5' and I'll show you something you may as well not bother plugging in... And at the point of being repetitious, for a home ~1G connection (or even 10G or 20G) it's absolutely pointless. What people think they're buying when they get a cheap 'cat 8' cable from $shopping_site is not, in fact, a to-spec cable made with quality, performance or conformity in mind. Buying a recognised, pure copper, branded cat 5e or 6 cable, will pull 10G all day without blinking. Why bother?
