Either for theory or for news, US primarily?
Richard Wolff does a great podcast - Economic Update
Anarchist News does a roundup podcast of recent stories often, I think it’s either weekly or bi-weekly. Clearly news related.
Marx Madness is pretty good for theory.
Others covered my favorites , but some more loosely fitting ones in no particular order: For the Wild, Working people, Coffee with Comrades, What’s Left of Philosophy, Total Liberation (recently ended), The Ex-Worker.
While not strictly about politics, the tech podcasts Tech Won’t Save Us and Trash Future are quite good and generally anticapitalist.
Elephant in the Room is an English language podcast from Germany.
