Indeed. The US "HD Radio" system has AM support in addition to FM and on AM it can broadcast up to 60 kbps (though most stations chose a 40 kbps mode with additional error correction to improve reception)[1]. Digital Radio Mondiale [2] (with the unfortunate acronym DRM) is another competing digital system system that can be used in the AM and shortwave broadcast bands, supports similar bitrates.
