There are only two aliquot sequences below 100000 which never reached 145 digits:
38052 (reserved by Clifford, last update 21.07.2019)
46758 (jacobs and Richard Guy, 25.12.2017)
Both of them look abandoned.

On top of those, there is only one aliquot sequence (95700, vacant) which reach 146 digits and 17 other sequences reach 147 digits.

I think it is possible to reach the milestone of 150 digits for all sequences below 10e5 in the near future.
