Background

As AI agents become integrated into investing workflows, interoperability standards may emerge to allow external agents to interact with brokerage systems. This question asks whether a major brokerage will publicly support such a standard.

Resolution Criteria

This question resolves YES if, on or before 2027-12-31, a top-20 US or Canadian brokerage publicly endorses a third-party open investing-agent standard by name.

For resolution purposes:

• “Top-20 brokerage” refers to one of the following

  • Charles Schwab

  • Fidelity Investments

  • Vanguard Brokerage

  • J.P. Morgan Self-Directed Investing / Chase

  • Morgan Stanley E*TRADE

  • Merrill Edge

  • Interactive Brokers

  • Robinhood

  • Webull

  • SoFi Invest

  • Public

  • Ally Invest

  • TD Direct Investing

  • RBC Direct Investing

  • BMO InvestorLine

  • CIBC Investor’s Edge

  • Scotia iTRADE

  • Questrade

  • Wealthsimple Trade

  • Qtrade Direct Investing

• “Publicly endorse” includes formal support, adoption, implementation, participation, strategic alignment, or production integration announced through:

  • press releases,

  • engineering blogs,

  • product or API documentation,

  • conference presentations,

  • investor materials,

  • regulatory filings, or

  • public roadmap announcements.

• The endorsed standard must:

  • be non-proprietary or governed by multiple organizations; and

  • enable interoperability between external AI agents and brokerage systems.

Examples that could qualify include MCP-derived finance standards, open financial-agent interoperability layers, agent identity standards, or open execution/portfolio coordination protocols.

Examples of brokerages that could qualify include Schwab, Fidelity, Robinhood, Vanguard, Interactive Brokers, Wealthsimple, Questrade, Merrill, Public, and E*TRADE.

Fine Print

The following do NOT count:

• Generic REST APIs;

• Internal proprietary standards;

• Passive compatibility claims without explicit endorsement;

• Undocumented integrations;

• Vendor partnerships lacking interoperability-standard support.
