Flight Crew Rejected Takeoff
Aircraft
As pilot monitoring; first officer was receiving a Line Check for a requalification; due to a lapse in currency due to COVID-19 pandemic.During the takeoff roll; I checked all airspeed indications on both sides of the cockpit per SOP.  At 100 knots entering the high-speed regime; I observed my airspeed indicator (Captain's); was now reading zero airspeed and there was an orange flag.  I realized the airspeed indicator had failed and I called out the reject and took positive control of the aircraft.The auto brakes activated in the RTO function and we cleared the runway and followed SOPs.The aircraft [was taken] out of service for further inspections.  There were no injuries to either crew or passengers and no damage to the aircraft.
While departing on the takeoff roll; the Captain initiated a rejected takeoff.  Once the rejected takeoff was initiated; I radioed Tower; advised of the reject and asked for vehicles due to possible hot brake conditions. I then addressed the passengers and asked them to remain seated. The rejected takeoff was initiated above 85 kts (because the RTO brakes engaged automatically) but prior to the 100 kt callout.  The Captain appropriately exited the runway and advised me that he had a witnessed a faulty airspeed indicator display which is why he elected to reject the takeoff.Once clear of the runway; and stopped on the taxiway; we initiated the Rejected Takeoff QRH/QRC procedures.  Once complete; we made proper notifications to the cabin crew; ATC; dispatch and company.The entire event was handled very professionally and efficiently by all involved.Once at the gate; the passengers were all booked on a later flight to ZZZ1 [airport]; the aircraft was removed from service; and the airspeed indicator was replaced.  The Captain and I operated the same aircraft back to ZZZ1 the next morning without issue.
Air carrier Captain reported the airspeed indicator failed on the Captain's side during takeoff roll resulting in a rejected takeoff.
