It is $100 for 1 Gbps, that's the rack rate nationwide.
If someone is paying $148 they are most likely on the original SPP plan from when gigabit first became available in 2017/2018.
The price in 2025 is $80 for 500 x 20 or $100 for 1000 x 35. If you are in a high split area you will have symmetrical speeds. Gigabit never had a 20 Mbps upload, it was always 35, maxing out at 40 with the over provision.
If you are paying anymore than $80 or $100 for internet service you should call up and be placed on the new pricing structure.
