Comcast, the largest consumer ISP in the US, supports IPv6 on its entire network, and all current modems they supply have it enabled. There are still customers on older modems, and customers who have brought their own modems that do not support it, so only about 50% of Comcast users are actually running IPv6.
Consumer wireless ISPs in the US are also doing pretty good. Verizon has 70% deployment, and AT&T and T-mobile are around 50%.
