Marsh acquires Wilshire to deepen wealth advisor reach

Marsh (NYSE: MRSH), the global professional services firm, has agreed to acquire Wilshire, a diversified investment advisory and analytics company that manages approximately $221 billion in assets and advises on roughly $1.6 trillion as of June 30, 2026.

The deal marks one of Marsh’s most significant moves into the financial advisor ecosystem to date, extending the firm’s investments platform into the advisor-led wealth segment and adding institutional-grade alternatives, model portfolios, and data analytics capabilities.

“The acquisition of Wilshire is an important step in growing Marsh’s investments business and strengthening our connection to the financial advisor ecosystem,” said John Doyle, President and CEO of Marsh. “By combining Wilshire’s capabilities with our global reach, open architecture, and expertise across public and private markets, we can help clients make better decisions and build resilient portfolios in an increasingly complex investment environment.”

A 50-year platform enters a new chapter

Founded in 1972 as an index and risk analytics provider, Wilshire has evolved into a full-service investment firm spanning multi-asset advisory, alternative investments, and proprietary indexing.

Its client base spans institutional investors, public and private retirement plans, endowments, foundations, and financial intermediaries. The company operates offices across the United States, Europe, and Asia.

For independent advisors and wealth management firms, the acquisition signals that Marsh is building the infrastructure to compete directly in model portfolio delivery, alternatives access, and data-driven investment solutions – areas where scale and technology are increasingly decisive.

Pat Tomlinson, President and CEO of Marsh People and Investments, described the rationale plainly: “Wilshire will expand our scale and capabilities, particularly in alternatives, model portfolios, and data and analytics, strengthening our platform for wealth advisors and asset managers.”

A private equity exit after five years of transformation

Wilshire’s sellers – CC Capital and Motive Partners – acquired the firm in 2021 and spent the intervening years modernizing its technology stack, completing three strategic acquisitions, and reshaping its go-to-market approach.

Those acquisitions – XTP, ParkLexington, and Lyxor – expanded Wilshire’s alternatives and institutional hedge fund managed accounts capabilities and deepened its connectivity with retirement providers and financial intermediaries.

CC Capital and Motive Partners worked with Wilshire’s management to strengthen its business through investments in technology, data infrastructure, artificial intelligence, product development and sales capabilities.

Jason Schwarz, CEO of Wilshire, said the timing of the sale was deliberate. “Wilshire has spent more than five decades building innovative, institutional-quality investment capabilities and delivering them to clients across institutional, wealth, and retirement markets,” he said. “Now is the time to join with Marsh, and through its global reach and resources, extend our platform, broaden our capabilities, and serve clients across the investment value chain.”

What it means for advisors

Marsh’s existing global distribution network – the firm operates in 130 countries with annual revenue of $27 billion and more than 95,000 employees – could substantially expand the reach of Wilshire’s investment products, particularly its alternatives platform.

The transaction follows Marsh’s broader acquisition-led growth strategy in the wealth and retirement space. The firm completed the acquisition of AltamarCAM, a European and Latin American private markets manager, in November 2026, and introduced Marsh BrightPath, a globally coordinated defined contribution retirement solution, earlier that same month. InvestmentNews has tracked how advisor-focused M&A is reshaping the wealth management landscape as larger platforms compete to offer a broader range of services.

Wilshire’s data and analytics platform – now fully cloud-based and API-enabled – is considered a key strategic asset. Its proprietary indexes and performance benchmarking tools are used across both institutional and retail advisory segments, giving Marsh a credible data layer to support its expanded wealth ambitions.

For advisors assessing how to benchmark, allocate to alternatives, or build model portfolios, the question going forward will be whether Marsh-Wilshire’s combined platform can deliver institutional-quality tools at the scale independent practices need.

The InvestmentNews Rising Stars 2026 report highlighted that the next generation of advisors is increasingly demanding better technology and investment infrastructure – exactly the gap this deal aims to close.

The agreement is expected to close in the first quarter of 2027, pending regulatory approvals and standard closing conditions. Financial terms were not disclosed.
