Orion adds Big Three asset managers to tax-smart portfolio platform
Orion, the wealthtech platform servicing $6.6 trillion in assets under administration, has added BlackRock, Fidelity Investments and Vanguard to its Tailored Allocation Portfolios offering. The move brings three of the largest asset managers in the United States into a technology layer that pairs their institutional model portfolios with Orion's Custom Indexing engine, allowing financial advisers to deliver tax-aware, personalised portfolios without abandoning the discipline of professionally managed models.
The addition takes the Tailored Allocation Portfolios roster to eight strategists since the platform launched in October 2025, with earlier partners including Janus Henderson, Russell Investments and First Trust Advisors. Orion's Custom Indexing capability, which had surpassed $17.1 billion in assets under management as of July 2026, underpins the offering by enabling gradual migration of concentrated or legacy positions into model portfolios while seeking to manage capital gains exposure.
Personalisation at industrial scale
The commercial tension this solves is not new. Advisers have historically faced a binary choice: adopt a third-party model portfolio for efficiency, or build bespoke portfolios for each client and absorb the operational cost. Orion's platform attempts to collapse that tradeoff by running institutional models through a customisation and tax-optimisation layer tuned to individual client circumstances, including concentrated equity positions and unique tax sensitivities.
"Advisors no longer want to choose between model portfolios and personalization," said Yi-Ching Wu, Executive Vice President of Wealth Management Product and Platform at Orion. "By bringing more institutional-grade strategies into Tailored Allocation Portfolios, Orion is expanding the range of solutions advisors can implement while maintaining the efficiency and scalability their businesses require."
The platform is integrated across Orion's adviser-facing suite, covering portfolio management, planning, CRM and outsourced CIO services. The company says 17 of the top 20 Barron's-ranked registered investment advisory firms rely on its technology.
The convergence angle: fintech infrastructure meets asset management distribution
The deeper strategic read is about where distribution power in wealth management now resides. BlackRock, Fidelity and Vanguard collectively manage tens of trillions in assets globally, yet their participation in a wealthtech intermediary's curated marketplace signals that technology platforms are becoming a meaningful gatekeeping layer between asset managers and end advisers. That is a structural shift with implications beyond the RIA channel.
For macro investors watching the wealth management stack, this mirrors dynamics already visible in retail banking and insurance: margin compression at the product level drives incumbents toward platform dependency, while the platform owner captures recurring fee flows and data on adviser behaviour and client preferences. Orion itself reports $211 billion in wealth management assets, a figure that makes it a credible distribution counterparty for managers of any scale.
The broader capital landscape reinforces the trend. Wealthtech infrastructure has attracted sustained institutional interest across the US and Europe, as private equity and strategic acquirers bet that the adviser technology layer will consolidate around a small number of all-in-one platforms. The model-portfolio market, which industry estimates place in the low trillions of dollars globally, is increasingly the battleground: whoever controls the customisation and tax-optimisation layer around institutional models may ultimately influence how those assets are allocated across equities, fixed income and alternative strategies.
For cross-sector investors, the question is whether this industrialised personalisation model translates to adjacent markets. Direct indexing and tax-overlay technology are already migrating from the ultra-high-net-worth segment toward the mass-affluent channel, and the same logic could extend to defined-contribution plans and sovereign retail investment schemes, particularly in markets where tax-advantaged wrapper complexity creates similar adviser pain points to the US RIA market.
