1. The 2025 Landscape in One Sentence
Machine-learning portfolio engines now handle US $1 trillion in client assets; the winners are the platforms that squeeze every post-tax basis point without sacrificing ease of use.

High-CPM blogs such as NerdWallet generate seven-figure annual revenue from linking readers to credit cards; the same referral model works for AI robo-advisors because platforms pay trailing commissions on Assets Under Management (AUM). By ranking them through the lens of after-tax alpha, you attract affluent readers who convert at above-average rates.

Portfolios sit in SIPC-insured custodial accounts; AI triggers only allocation instructions, not custody.

Wealthfront and Betterment require U.S. residency; consider Syfe or Scalable Capital if you live in the EU or Asia.
Q3. How often is this ranking updated?
