Departing from DIA we lost Left GPS taxiing out.  On climb out we lost both GPS and had transponder failure.  Alerted ATC and they knew about it; said everyone was having the same issue and it would go away 30 miles east of Denver.  We eventually got both GPS back and transponder fail went away 60nm east if Denver climbing through FL260.   Worked fine rest of the flight. Heard numerous aircraft having the same issue near Denver.  Alerted Dispatch via ACARS that it might be a 5G interference issue but they said 5G wasn't activated in DEN yet; so I have no idea what's causing the issues there then but it's widespread and hitting all the aircraft.
Air carrier Captain reported departing DEN the loss of GPS and transponder.
