Who will win the robo advisor IPO race?

It's been a decade since the launch of the industry's leading independent digital advice platforms -- Betterment, Wealthfront and Personal Capital. The question that now remains for all three: who will cross the IPO finish line first? The companies continue to churn the possibility of going public, while raising millions in additional funding. But there are doubts around the market viability of automated advice's aging upstarts. In terms of assets, the trio has kept their positions in the market respectively, with Betterment leading all independents with over $10 billion in AUM, followed by Wealthfront's $7.4 billion and Personal Capital's $4.9 billion.
