Marsh, the global risk, investments and consulting firm, agreed on 10 November 2026 to buy Wilshire, the investment consulting, index and analytics firm, from Motive Partners and CC Capital, with the Marsh Wilshire acquisition expected to close in the first quarter of 2027 and no price disclosed. Fintechbits compared the figures with Marsh’s own March 2026 AltamarCAM announcement: Wilshire’s $221 billion of assets under management equals about a third of the $692 billion that Mercer, Marsh’s investments business, reported managing at 31 December 2025, and the deal follows Mercer’s agreement to buy the €20 billion private markets manager AltamarCAM. The dates differ, since Wilshire’s figure is as of 30 June 2026, so the ratio is approximate (Mercer’s AltamarCAM release).

What Marsh is buying

According to Marsh’s announcement, Wilshire was founded in 1972 as an index and risk analytics provider and has grown into a firm combining multi-asset advice, alternative investments and indexes with its own data and technology. It manages $221 billion and advises on $1.6 trillion, and its staff in the US, Europe and Asia will join Marsh at completion.

Marsh says the Marsh Wilshire acquisition takes its investments business into the advisor-led wealth segment and adds analytics and alternatives, while strengthening what it offers pension plans, endowments and foundations. Pat Tomlinson, president and chief executive of Marsh People and Investments, said: “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.”

John Doyle, president and chief executive of Marsh, called the deal “an important step in growing Marsh’s investments business and strengthening our connection to the financial advisor ecosystem.” Marsh reports annual revenue of $27 billion and more than 95,000 colleagues, which makes Wilshire a bolt-on in revenue terms even if it is large in assets.

What Motive Partners and CC Capital did with Wilshire

The sellers’ release from Motive Partners and CC Capital describes a five-year rebuild. The two firms agreed to buy Wilshire Associates in October 2020, according to Motive’s own archive, and say they invested in 2021. They installed a Motive executive as chief executive and later executive chairman, moved the business onto cloud and API-based technology, and bought XTP, ParkLexington and Lyxor to grow its alternatives and hedge fund managed account offering.

Motive is a fintech-only investor, spanning banking and payments, capital markets, data and analytics, insurance and wealth. That makes the Marsh Wilshire acquisition a fintech private equity exit as much as an asset management deal. Motive has also been buying, including the deal Fintechbits covered in its Motive Partners Mobius piece.

Fintechbits analysis

Why the Data Business Matters Most in the Marsh Wilshire Acquisition

The headline asset figures flatter the deal. Most of the $1.6 trillion is advised, not managed, and consulting relationships can walk. Marsh even lists client consents as a closing condition, a sign of how much of the value depends on clients accepting a new owner.

The better asset is the one Wilshire started with: indexes and analytics. Index and data businesses earn recurring licence fees, and they are the hardest piece for a consultant to build from scratch. Motive’s own pitch, that it turned Wilshire into “a modern, scalable data and analytics platform with real strategic scarcity value”, is a sales line, but it points at the right thing.

For Marsh, the logic is reach. Mercer already runs a large institutional business. Wilshire’s model portfolios and advisor tools give it a route to independent wealth advisers, a market where scale players and fintech platforms compete for the same shelf. Paired with the AltamarCAM purchase, the Marsh Wilshire acquisition shows Marsh building a private markets and wealth platform through acquisitions, a pattern Fintechbits has tracked across the sector in its look at why fintechs buy rather than build.

The missing price is the weak spot in the Marsh Wilshire acquisition. Without it, nobody outside the deal can judge whether Motive and CC Capital earned a strong return or simply found a large buyer.
