My impression that a NO answer would disqualify you for an ISP /32, but 
perhaps ARIN staff can clarify.  NRPM point C seems to state 
that YES is a requirement:

 Initial allocation criteria

To qualify for an initial allocation of IPv6 address space, an 
organization must:

   1. be an LIR;
   2. not be an end site;
   3. *plan to provide IPv6 connectivity to organizations to which it
      will assign IPv6 address space, by advertising that connectivity
      through its single aggregated address allocation; and*
   4. be an existing, known ISP in the ARIN region or have a plan for
      making at least 200 /48 assignments to other organizations within
      five years.
