Jota has spent the season on loan at Wolves - with 17 goals and five assists coming from 44 outings in the Championship - and the title winners have previously indicated that they will take up the option to complete a full-time deal.
However, the newly-promoted Premier League side are yet to confirm the transfer and Jota has suggested that no announcement is imminent.
The 21-year-old told Mais Futebol: "For the next season I still have nothing defined, I still have nothing signed.
"I want to stay. Everything that has happened this season leads me to believe that the next season can be good for me in the Premier League but, as I said, nothing is still signed and I can not give anything for granted."
Wolves have been linked with a wide range of players in recent weeks, but are yet to make any signings ahead of next season.
