With six grands prix of the season remaining, Marussia have wasted no time in announcing Bianchi will again drive for them for next year.
Team principal John Booth has insisted Bianchi's new contract is not linked to the fact Marussia will be powered by Ferrari from 2014, with the Frenchman a part of the Maranello marque's driver academy.
In the meantime, Chilton appears to have been left in limbo, although the 22-year-old from Reigate appears unconcerned.
"I'm still working with the team, and the team are obviously keen to sign both of us," said Chilton.
"It's just we're not at the same stage as Jules. I wouldn't say we're late, it's just we're working on things and they're progressing nicely.
"Although it's taking us longer, we're not in any mad rush. We've still six races to go, plenty of time, but I am keen to get it done pretty soon.
"I know the team want me, and when the team want you it's good to get the deal done.
"For now I'm focusing on my driving. Things have started to improve the last couple of races, and hopefully I can maintain that to the end of the year."
Part of Chilton's problem is his sponsorship package as the Briton has more than 30 separate investors behind him.
Chilton has given up part of his future earnings with the formation of a company under the Enterprise Investment Scheme.
Investors paid anything from £20,000 upwards to back Chilton, with the aim of a return down the line should he progress his career.
"You have to get the sponsors and investors, like any other driver," added Chilton.
"But you need everything in place before you get anything done, and it's one of the things I'm working on.
"You never know what can happen in Formula One, but the option is there, it's just whether I can get everything together.
"It's not as simple as it sometimes looks, but I believe I've proven I deserve a chance, it's just trying to get the deal done."
Booth appreciates the difficulties behind Chilton's funding as he said: "There's nothing to read into Max's situation at all. We are talking with him.
"We've always made it plain we'd like to run the same drivers next year, so we've got half the job done.
"It's just about timing. They're quite big, complicated deals. They don't happen overnight."
