Orion Tailored Allocation Portfolios just picked up the three largest asset managers in the United States. The wealthtech platform added BlackRock, Fidelity Investments and Vanguard to the program, which pairs third-party model portfolios with Orion’s Custom Indexing technology.

What Orion Tailored Allocation Portfolios Now Hold

Orion Tailored Allocation Portfolios now list the three alongside Brinker-Main Management, First Trust Advisors, Frontier Asset Management, Janus Henderson and Russell Investments, bringing the shelf to eight strategists since the October 2025 launch. The program is available across Orion Wealth Management, the Orion Investment Portal, Wealth Advisory and Orion OCIO.

The mechanism is the interesting part. Advisors pick a manager whose investment approach matches their own, then build custom models on that foundation, with Custom Indexing enabling gradual migration of assets for clients holding concentrated positions, legacy holdings or particular tax sensitivities. Switching model providers has traditionally been expensive enough that advisors simply did not do it often, because selling out of legacy holdings triggers the tax bill.

Why the Vanguard Addition to Orion Tailored Allocation Is Different

Here the common reading of the Orion Tailored Allocation news undersells it. The assumption is that these models are commodity products already available everywhere, so the news is only a logo win. That holds for the BlackRock and Fidelity ranges. It does not hold for Vanguard.

Vanguard launched its first custom model portfolios last month, covering multi-asset and single-asset strategies, and named only two implementation platforms: Vestmark, run by SS&C Black Diamond, and Orion Tailored Allocation Portfolios. Being one of two launch venues for a genuinely new Vanguard product is a different achievement from stocking models anyone can already buy.

The wider context is that all three managers have been expanding model line-ups. Fidelity launched turnkey models focused on private markets in March. Asset managers are treating models as a distribution channel, which means platforms that can implement them well acquire leverage they did not previously have.

The Tax Layer Is the Orion Tailored Allocation Product

Orion Tailored Allocation manager logos matter less than the tooling underneath, and the demand data supports that. Fuse Research Network found that advisors rank tax loss harvesting as the customisation capability clients most want, with tax optimisation mattering most to advisors running $500 million or more. Orion’s own February survey of 571 advisors found more than half planning to adopt or expand tax optimisation services within five years.

Direct indexing and tax-managed transitions are among the most crowded corners of wealthtech, with custodians, turnkey asset management platforms and dedicated direct-indexing shops all selling the same promise. Pairing that technology with the broadest possible roster of model providers makes the tax-management layer, rather than any individual manager’s models, the thing advisors are buying. Ron Pruitt, who leads Orion Wealth Management, framed it as letting advisors start from an investment philosophy they already trust while adapting to each client. Yi-Ching Wu, the platform product lead, tied growth since launch to advisors refusing to choose between models and personalisation.

What Orion Tailored Allocation Has to Prove

Whether the Orion Tailored Allocation differentiation holds depends on how the tax-transition tooling performs against dedicated competitors in live accounts, which no announcement can settle. The claim is that a transition costs less in tax than it saves in fit. That is measurable, and nobody is publishing the measurement.

For advisors the practical draw is consolidation, standardising on one platform for both the household-name models clients ask for and specialist allocations from firms like Frontier or Janus Henderson, rather than running several vendor relationships to get both. That argument works only if the shelf stays broad.

So watch adoption rather than announcements. How many advisors on the platform really do move assets into models from the new managers, against how many stay with providers they already used, is the number that shows whether an expanded shelf changes behaviour. Watch too whether Vanguard extends its custom models beyond the two launch platforms, because exclusivity of implementation is worth more to Orion than any algorithmic overlay it can build itself.
