The 24-year-old forward was a target for both Norwich and Bristol City in the transfer window but remained at Selhurst Park.
When asked whether the player was set for a new deal, Pardew said: "It's not something I'm aware of.
"We obviously have to keep an eye on players' contracts as they run down, but I think we are pretty comfortable where we are.
"Signing Yannick (Bolasie) was a real boost for us and having key players under long contracts bodes well for going forwards."
The Eagles boss continued: "I was very impressed with him (Gayle) last Sunday. If he had scored two goals he would have been man of the match, and he could have, he was so unlucky with a couple of chances.
"That is what he gives us and he has worked his way into the team.
"He will play on Saturday and hopefully he will score."
