Set up by TS Eliot and friends, the PBS provides information and reviews on contemporary poetry for readers.
The benefit on 3 June will take place at University College London.
Readers at the event will include Duffy, John Agard and Elaine Feinstein.
The PBS said more than 1,000 people had signed a petition submitted to Arts Council England asking for it to reconsider its decision.
