The 23-year-old from Bristol will go ahead of Mark Selby at the top of the list when the rankings are revised at the end of this event. He will be the tenth No 1 in snooker history, after Ray Reardon, Cliff Thorburn, Steve Davis, Stephen Hendry, John Higgins, Mark Williams, Ronnie O'Sullivan, Neil Robertson and Selby.
But for now his mind is fixed only on winning the new ranking event in Chengdu and claiming the bumper £125,000 top prize. Trump will face Neil Robertson or Shaun Murphy over 19 frames on Sunday.
The left-hander did the bulk of the damage against Ebdon in the first session, building a 7-1 lead with top breaks of 61, 55, 68, 53 and 53. In the first frame of the evening session he made a 51 clearance to extend his lead. And a run of 63 in the next helped Trump move a step close to his first ranking title since the williamhill.com UK Championship last December. Sunday will see him contest his fifth ranking final and third in China.
"It's a proud moment to get to number one, it has been a long road to get there," said Trump, who turned pro in 2005 at the age of 16. "I played well in the first session today and was able to build a good lead and save some energy.
"Peter didn't play his natural game. At the start of the match he was trying to put me off and put me out of my rhythm. I told myself before the match to stay patient and wait for my chances. In the end he bogged himself down for the first couple of frames. Then he made a century in reasonable time. When he plays his normal game instead of trying to slow people down he's a better player.
"It will be tough either way in the final. I've got a better record against Shaun and it might be a more free-flowing game against him. The way I feel, I fancy beating both of them."
