The Bristolian surged into a clear early lead in the opening session, with only Ebdon's century in frame four preventing a whitewash.
Trump then put himself within two frames of the final before closing out the win quickly in the second session a few hours later.
Trump will overtake Mark Selby as the new world number one with the semi-final win, while 2006 world champion Ebdon's hopes of a return to the top 16 have been dashed, with only a run all the way to his 10th ranking title being enough to catapult the veteran back into the sport's elite.
Trump put in breaks of 61 and 55 on his way to a 3-0 lead before Ebdon completed a 106 clearance to pull one back heading into the mid-session interval.
It would be the 42-year-old's only success of the opening eight frames, however, as Trump whitewashed the post-break frames to move within two more of a spot in the final.
Ebdon initially appeared to have shaken off the inconsistency which blighted his early game when the two players returned for the final session, but with frame nine all but won a number of missed reds allowed Trump in to steal with a clearance.
And a break of 63 was enough to hold off the trademark Ebdon hopes of an unlikely salvage via snookers and put Trump into Saturday's final in emphatic fashion.
The ranking event pays out an estimated total prize money of £600,000, with £125,000 going to the eventual winner.
