Orion is attempting to resolve the historical tension between institutional-grade model efficiency and individual client personalization by integrating major asset managers into its specialized portfolio architecture. By adding BlackRock, Fidelity Investments, and Vanguard to its Tailored Allocation Portfolios, the company is positioning its technology to allow advisors to apply custom indexing to widely recognized third-party strategies. This move aims to capture a larger share of the wealth management market by offering a scalable way to manage tax sensitivities and concentrated positions without abandoning established investment philosophies. As of June 30, 2026, Orion services $6.6 trillion in assets under administration, signaling the massive scale at which these personalized transitions must now operate.
BlackRock, Fidelity, and Vanguard Expansion
The addition of BlackRock, Fidelity Investments, and Vanguard marks a significant expansion for Orion’s Tailored Allocation Portfolios, which launched in October 2025. These three entities join a growing roster of eight leading strategists, which previously included Brinker-Main Management, First Trust Advisors, Frontier Asset Management, Janus Henderson, and Russell Investments. This expansion is designed to provide advisors with a broader selection of institutional-grade models that can be immediately processed through Orion’s Custom Indexing technology.
By running standard or custom ETF and mutual fund models from these major managers through its indexing engine, Orion is testing whether it can bridge the gap between mass-market model portfolios and highly bespoke client needs. The company’s objective is to enable advisors to migrate assets from legacy holdings or concentrated positions into these new models gradually. This process is intended to manage capital gains and improve after-tax outcomes for clients over time. The strategic importance of this integration is underscored by the scale of Orion's existing infrastructure; the company's Custom Indexing technology reported surpassing $17.1 billion in assets under management as of July 31, 2026. This integration suggests a move toward making high-touch, tax-smart investing a standard feature of institutional-grade model management rather than a manual, labor-intensive exception.
Scaling Personalization via Custom Indexing
Orion is positioning its Tailored Allocation Portfolios as a solution to a long-standing industry tradeoff: the choice between the efficiency of third-party models and the ability to deliver a customized investment experience. The technology allows advisors to select an investment philosophy they already trust—such as those provided by the newly added asset managers—and then adapt those portfolios to reflect a specific client's unique goals, preferences, and tax circumstances. This capability is being deployed across multiple Orion platforms, including Orion Wealth Management, Orion Investment Portal, Wealth Advisory, and Orion OCIO.
The business implication for wealth management firms is the potential for increased scalability in personalized service. Rather than building custom portfolios from scratch, advisors can leverage the disciplined, professionally managed models of major asset managers while utilizing Orion's technology to handle the granular details of tax-loss harvesting and individual preference adjustments. This approach seeks to maintain the efficiency required for growing advisory businesses while meeting the rising demand for individualized client outcomes. As the company expands its range of solutions, it is betting that the ability to combine institutional discipline with custom indexing will drive deeper integration within the thousands of independent advisory firms it currently supports.

FinanceInsyte's Take
In our view, Orion is executing a sophisticated play to commoditize personalization within the wealth management sector. By embedding the models of "Big Three" style asset managers like BlackRock, Fidelity, and Vanguard into its indexing engine, Orion is attempting to remove the "complexity tax" that typically prevents advisors from offering bespoke services at scale. This isn't just about adding more names to a list; it is about creating a hybrid delivery model where institutional discipline and individual tax optimization are no longer mutually exclusive. If successful, this could force a shift in how mid-to-large scale RIAs approach model management, moving away from static allocations toward dynamic, tax-aware frameworks. The massive scale of Orion’s $6.6 trillion in assets under administration suggests that the infrastructure for this shift is already in place, making this a significant move toward the institutionalization of personalized wealth management.
