Not sure what "a lower median net worth at the 99th percentile" means (median is net worth level at the 50th percentile), but 1 in 100 American households (not individuals) indeed have over $13 million net worth: https://fred.stlouisfed.org/series/WFRBL99T999309

This threshold has about doubled since 2010, which should not be too surprising as house prices more than doubled and the S&P500 increased six fold in the last 15 years.

~"Minimum Wealth Cutoff for the 99th to 99.9th Wealth Percentiles" in that link reads to me as 1 in 1,000 households have a net worth over $13 million, not 1 in 100.~

edit: seems like I'm wrong

No, that would be the the maximum cutoff, not the mimumum. That maximum, which is also the minimum cutoff to enter the 99.9 percentile (the 0.1%, or 1 in 1000) is almost 50 million dollars: https://fred.stlouisfed.org/series/WFRBLTP1311
