The Scot had been linked with moves to Ferrari, McLaren and Mercedes with Felipe Massa's, Lewis Hamilton's and Michael Schumacher's features at the respective teams unclear.
His career best fourth in Singapore moved him ahead of the seven-time world champion in the drivers' championship, and just seven points behind Massa - a timely reminder of his pace.
The 26-year-old has a long relationship with the Silver Arrows, having taken the DTM title in 2010 for the marque, and that association is one of the reasons he was placed with a Mercedes powered team in Formula 1.
Di Resta is confident in his own abilities as a driver, and is sure he could be competitive with a top team, but insists he is happy with Force India.
"I would like to think I am capable of stepping up to one of the bigger teams," said Di Resta.
"I have raced against the drivers at the top in the past and have had great battles with them and beaten them, but I'm not getting carried away.
"When the time is right hopefully someone will step up and give me the chance to do that because I want to be in a car that wins races week in, week out.
"I have worked with manufacturer teams before and there is a slight difference, but I will keep focusing on the job in hand just now because this is where my loyalties lie at the present.
"I enjoy being part of this team, even though it's hard work because the infrastructure we have is not quite what others have.
"But we've shown when you gather it all together you can get the performance, it's just making sure that happens weekend in and weekend out."
Di Resta recently joined Richard Goddard's management company, which is responsible for Jenson Button, following an acrimonious split from Anthony Davidson earlier in the season.
Goddard is sure performances, such as the Scot's in Singapore, will soon see his new client in demand.
"He was fantastic in qualifying, and it was a fantastic drive from start to finish. It was brilliant and I'm ecstatic," Goddard said.
"It highlights the talent he has, although every team has been able to see how consistent he is anyway, and every team wants consistent qualifiers and consistent racers.
"It is one of Jenson's massive strengths that for lap after lap he produces the same time, and it's about getting the majority out of the car and also being clever in the use of tyres.
"Paul has also been able to demonstrate that, and the closer you finish to the podium and are on the podium, that's when you get recognised by more and more teams.
"So that's what his result yesterday [Tuesday] will do for him. It will give him a lot more visibility.
"Obviously he is contracted to Force India at the moment, so there are no issues from that perspective.
"It's not like he is having to look around for another drive, but if he were looking, it would be a fantastic result."
