The Anadolu Agency said police had arrest warrants for of 140 people, including businessmen and former employees of the Gulen-linked Bank Asya, which was seized by the government last year, AP reported.
On Monday, 101 people were taken into custody in Istanbul and eight other cities.
The government has declared Gulen's movement a "terrorist" organization and has clamped down his supporters, seizing newspapers, television stations and other businesses associated with the cleric.
Anadolu says those detained Monday are suspected of being members of a "terror group" and of providing funds and making propaganda for the Gulen movement.
