Departing DEN as soon as we took off we lost both GPS systems and Transponder 1 and 2.  Systems returned to normal ops at FL260.  ATC informed us numerous aircraft reporting same issue. On arrival into the airport numerous received spurious TCAS alerts.  TCAS was already set to TA only due to reports from preceding aircraft into airport of TCAS alerts.   Turned off TCAS system and landed safely.  Thrust reverser also showed an issue on taxi in; possibly related.
B737 Captain reported erroneous TCAS alerts on arrival; with GPS and transponder failure on departure from DEN.  Captain and other aircraft suspected possible GPS jamming.
