This market resolves “Yes” if 50-year GSE-eligible mortgages are approved by December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No.” A qualifying approval requires that either: A) The Federal Housing Finance Agency (FHFA) officially approves 50-year mortgages. An approval alone will qualify, regardless of whether Fannie Mae and Freddie Mac subsequently update their guidelines. B) Fannie Mae or Freddie Mac officially makes 50-year mortgages eligible for purchase or guaranty. Only changes regarding new-origination, first-lien, fully amortizing 50-year mortgages will qualify. Other arrangements (e.g., limited pilots, post-origination term changes, junior-lien or revolving products, loss-mitigation programs, etc.) will not be considered. The primary resolution source is official information from the FHFA, Fannie Mae, and Freddie Mac; however, a consensus of credible reporting will also be used.
