Sprint and Verizon are CDMA and I'm not aware of either of them having plans to change (other than their adoption of LTE). MetroPCS is CDMA but is planning to switch to GSM, especially if their merger with T-Mobile goes through as expected. AT&T and T-Mobile are the large US carriers that use GSM.
In terms of the larger prepaid carriers, Virgin Mobile/Boost (both owned by Sprint), Republic, and Cricket are CDMA; Straight Talk (which uses either AT&T or T-Mobile's network) and T-Mobile are GSM. And Metro, again, which is CDMA now but will be switching to GSM.
