Marsh Agrees to Buy Wilshire to Expand Advisor-Led Wealth Reach

Marsh (MRSH ) announced the agreement on November 10, 2026, to acquire Wilshire, a global investment consulting, solutions and analytics firm serving institutional investors and financial intermediaries, from CC Capital and Motive Partners. Financial terms were not disclosed.

Wilshire reported $221 billion in assets under management, covering discretionary and non-discretionary services, and $1.6 trillion in assets under advisement, a total that includes managed assets and advisory relationships where it does not directly manage client portfolios, as of June 30, 2026. Its wealth and retirement solutions support thousands of defined-contribution plans. The gap between the two asset totals reflects the reach of Wilshire’s advisory relationships beyond the portfolios it manages directly.

Advisor-Led Wealth and Alternative Investments

Marsh expects the acquisition to expand its investments business into the advisor-led wealth segment, add analytics and alternative-investment capabilities, and strengthen its offering to institutional investors across public and private retirement plans, endowments and foundations. The plan connects Wilshire’s institutional consulting franchise with Marsh’s existing work for institutional and wealth clients.

Pat Tomlinson, president and CEO of Marsh People and Investments, said Wilshire would expand Marsh’s scale and capabilities particularly in alternatives, model portfolios, and data and analytics for wealth advisors and asset managers. Those additions would give Marsh a broader set of investment tools to pair with Wilshire’s advisory relationships.

Expansion Under CC Capital and Motive

Founded in 1972 as an index and risk-analytics provider, Wilshire now combines multi-asset advice and solutions, alternative investments and indexes with proprietary data, technology and analytics. The sellers describe its current platform as fully cloud-based and API-enabled, built around a unified data and analytics stack spanning investment solutions and alternatives.

CC Capital and Motive Partners said in a separate announcement that they invested in Wilshire in 2021 and worked with management on technology and data infrastructure, cybersecurity, AI-enabled workflows, product development, sales execution and leadership recruitment. Executive Chairman Tom Sanzone was among the executives appointed during that ownership period.

The sellers said Wilshire’s acquisitions of XTP, ParkLexington and Lyxor under their ownership expanded its alternatives and institutional hedge-fund managed-account offerings and deepened connections with financial intermediaries and retirement providers. That history helps explain Marsh’s emphasis on alternatives and advisor connections: the business being acquired is broader than the index provider Wilshire was at its founding.

Wilshire CEO Jason Schwarz said: “Joining Marsh’s investment business will enable Wilshire to build on that progress and continue delivering independent insight, investment solutions and technology-enabled services to clients globally.”

Wilshire’s colleagues across offices in the United States, Europe and Asia will join Marsh upon completion. The companies expect the transaction to close in the first quarter of 2027, subject to regulatory approvals, client consents and other customary closing conditions. The strategic case is a broader platform spanning institutional consulting, advisor-led wealth and alternative investments; the immediate requirement is securing the approvals and consents needed to complete that combination.
