Other NZX-listed companies like Ryman Healthcare and Mainfreight, have dropped in the rankings.
Sharesies spokesperson Erin Avery says US markets have become more accessible in recent years, and look increasingly attractive too.
She says US markets have been generating strong returns, and people want to be involved in new trends like AI.
