The 2008 Canadian Grand Prix winner leads the LMP2 standings heading into this weekend's Monza six-hour race after finishing runner-up in class at the Le Mans 24 Hours last time out with team-mates Louis Deletraz and Rui Andrade.
Kubica has raced in LMP2 with Deletraz since his full-time switch to sportscars in 2021, winning that year's European Le Mans Series crown with WRT and only missing out on victory at Le Mans to a freak electrical failure on the final lap, before the pair switched to Prema for the 2022 WEC and took second at Le Mans.
But with the secondary prototype category being dropped from the WEC next season, and WRT moving up to the top class to run BMW's factory LMDh programme, Kubica has actively sought out a Hypercar berth as he believes "it will be a natural step for me to give continuity" to his sportscar career.
The ex-BMW-Sauber, Renault and Williams Formula 1 driver told Autosport at Monza: "[LMP2] will be still in Le Mans, but of course, I would like to compete on the highest level in WEC.
Opinion: The inevitable Le Mans change that will still be lamented
"I would like to compete with the possibility of doing a serious programme and having an opportunity.
"I know there are many good drivers around, but I still think I can offer a good service and a lot of experience, especially with the new projects with relatively new cars.
"I think someone who drove many different cars and I have to say I learned a lot in F1, it can be valuable.
