Hubbard attended college at Butler University and earned his law degree from Georgetown University.

He then took work with the United States Department of Justice as private secretary to William H. H. Miller and an assistant attorney in the Indian Depredation Claims Division, before taking up private practice in Chicago.
He became a railroad promoter in the late 1890s eventually practicing law in Nome, Alaska, for a time. Hubbard was an advocate for statehood and proposed a bill calling on Congress to grant such status to the Territory of Alaska. While President of the Senate, he opted to place a referendum on the ballot to establish an eight-hour work day in Alaska. He served on the Alaska Territorial Board of Education. By 1920, Hubbard had become a Republican.
