There are some interesting plots (including future predictions) from the IERS Bulletin A data here showing the insertion of leap seconds over time to balance against changes in the Earth's length of day: https://datacenter.iers.org/singlePlot.php?plotname=BulletinA_All-UT1-UTC&id=6 https://datacenter.iers.org/singlePlot.php?plotname=Bulletin... It isn't obvious yet to me that there will certainly be a negative leap second (or even a positive one, for that matter) needed in the upcoming years, but predictions farther into the future here are difficult. However, the changes in the length of day that have kept UT1-UTC so close to zero the past several years are very interesting, and as a result we haven't needed a leap second since the end of 2016! And since the BIPM decided a few years ago to abandon leap seconds by 2035, if this somehow manages to hold for several more years, it's possible that we may not even see a leap second insertion (or deletion) again.
