Speaking in his press conference ahead of the match with Manchester City, Moyes confirmed that he was expecting to keep the former Lorient centre-back.
"We've told Lamine Kone he will be offered a new contract in September," Moyes said.
"Lamine is a big part of the team, the fans like him and we need him. Lamine is very much part of my plans. We will renew his contract on the 1 September"

The Sunderland boss has been busy bringing in players to the Stadium of Light this week, having secured three talented youngsters from his former club Manchester United in time for the club's opening Premier League match with Manchester City at the weekend.
Defenders Paddy McNair and Donald Love joined on permanent deals on Thursday, while midfield starlet Adnan Januzaj arrived on a season-long loan on Friday.
But just as big news as those new faces has been the ongoing reports surrounding Everton's alleged chase for the Black Cats' star centre-back Kone.
Lamine Kone scores for Sunderland
The Toffees are flush with cash for strengthening their side after selling John Stones, and it was said that a deal for the Sunderland man was good as done earlier in the week, only for the transfer to stutter, and for now it appears to be very much up in the air.
The Ivorian played a vital role in keeping the side up last season after arriving from Lorient in January. His brace in a win over the Mersysiders in May assured Sunderland's place in the top flight and sent fierce rivals Newcastle down into the Championship, but it looked like his time on Wearside would be short-lived after his transfer request that was circulated in the media, such as the Guardian, this week.
The problem with the player seemed to be regarding a promise of a new contract that is yet to arrive, so Moyes' public confirmation that a contract would be offered once the transfer window has closed should be notice to the 27-year-old that he will get his wish, if that is really what he wants - but only if he is open to remaining with the Black Cats.
