Williams have an option of extending his contract for another season, but so far this season the 25-year-old has exceeded all expectations of him and the team is hopeful of keeping him on as Felipe Massa's team-mate past 2015.
"Personally I don't see a reason to look around at this moment," Bottas told Autosport when asked whether or not he is happy driving for Williams.
"But it's too early to say – it's better to wait for confirmation, and we will speak when we have something to say.
"I should just focus on this moment, this year, then once we know what is going to happen next year we can focus for that, and then we will see."
Williams have performed admirably so far this season, with Bottas in particular impressing after finishing on the podium in four of the last races.
They are currently in fourth place on the Constructors' Championship standings but are only 10 points behind Ferrari with seven races left in the season.
With no major technical changes expected for next season, Bottas believes Williams will continue to finish record strong results after making the switch from Renault to Mercedes power units at the start of the current season.
"I really think this team is not at its peak yet," Bottas added.
"I really think the direction is right, and I am confident this team can still be better than what we have seen this year. So that's why I am really confident here with me continuing."
