Data sourced from Dakota Marketplace, the global LP and GP intelligence platform trusted by thousands of investment professionals. Learn More | Book a Demo

The largest UCITS sub-advisory platforms in Europe in 2026 are Mediolanum ($75.0 billion of sub-fund assets run by outside managers), Banca Generali's LUX IM, Russell Investments, Lumyna (Generali Investments) and Lombard Odier's PrivilEdge. Together with Fideuram, Architas, Fineco, NEF and Pacific Asset Management, these ten platforms control $188 billion, about two-thirds of the market.

Key Takeaways

• Industry estimates put sub-advised UCITS assets across Europe at around $1.5 trillion. Dakota's filings-based map of Ireland and Luxembourg identifies $280 billion run by outside managers, across 2,036 seats held by about 850 investment firms (Dakota analysis of CBI and CSSF registers and funds' published annual reports, September 2026).
• The ten largest selector platforms hold $188 billion, or 67% of those assets. Mediolanum alone accounts for 27%.
• The channel is open to every kind of manager: where the contracting entity's location is stated, UK firms hold 25% of seats, Swiss firms 17%, US firms 14% and German firms 11%.
• Multi-asset (500 seats), global equities (359) and global fixed income (262) are the most outsourced strategies.
• Host ManCos such as Carne and Waystone run 45% of all seats ($79 billion). Their route to a mandate is different from the selector platforms'.

What is a UCITS sub-advisory platform?

A UCITS sub-advisory platform is a fund group that sells UCITS funds under its own brand and hires outside investment managers to run them. Dakota counts 125 such platforms and management companies across Ireland and Luxembourg, delegating $280 billion of sub-fund assets to about 850 outside firms as of September 2026.

A few terms recur throughout this series:

• UCITS (Undertakings for Collective Investment in Transferable Securities) is the EU framework for regulated, liquid funds. It lets one fund be sold across Europe, Asia and Latin America under a single passport.
• A management company (ManCo) is the regulated company legally responsible for a UCITS. Under the UCITS Directive it can delegate portfolio management to another firm but keeps responsibility for that firm's oversight.
• An umbrella fund is one legal fund (an Irish plc, ICAV or unit trust, or a Luxembourg SICAV or FCP) that contains many sub-funds, each with its own strategy, ISINs and assets.
• A sub-advisor, also called a delegated investment manager, is the outside firm appointed to run a sub-fund or a sleeve of one.
• A seat is one manager on one sub-fund. A sub-fund split between three managers has three seats.

The ManCo is regulated by the Central Bank of Ireland (CBI) or by Luxembourg's Commission de Surveillance du Secteur Financier (CSSF). Both publish registers of every authorised umbrella and sub-fund, and each umbrella's audited annual report names its delegates.

Two kinds of firm sit in the ManCo seat, and they matter differently to a fundraiser:

• Selector platforms build their own-branded range and choose the outside managers. They are the buyers, and they are the subject of this ranking.
• Host ManCos carry the regulatory licence for other firms' umbrellas. There, the promoter usually decides who manages the money. They are covered separately below.

How big is Europe's UCITS sub-advisory market?

Industry estimates put sub-advised UCITS assets across Europe at around $1.5 trillion (€1.4 trillion). Within that, Dakota's filings-based map of Ireland and Luxembourg identifies $280 billion of sub-fund assets run by outside managers, across 2,036 named seats at 341 umbrellas, with same-group delegation excluded.

The two figures measure different things, and the difference matters to a fundraiser.

The market-wide figure shows the channel is large. The map shows which seats an outside manager can actually compete for, and who holds them today.

The two registers list 2,052 UCITS umbrellas: 550 in Ireland and 1,502 in Luxembourg. Between them they hold 16,342 sub-funds. Most of those are run by the promoter's own investment team. Dakota's research reads each umbrella's latest audited statements and prospectus to find the minority that hand portfolio management to an outside firm. Of those umbrellas, 615 name their delegates in their filings, and 341 use at least one outside manager.

Two rules keep the map to seats an outside manager can win.

Same-group delegation is excluded. When a UBS umbrella delegates to UBS Asset Management in Zurich, or a Franklin Templeton umbrella to Western Asset, the filing names a "sub-advisor". But no outside manager could ever win that seat, so it is not counted.

Assets are counted once per sub-fund. A multi-manager sub-fund with three sleeves is counted at its total size, not three times. The figures are sub-fund assets. They are not the size of any single manager's mandate.

The market is also more international than its reputation suggests. Where the filings state the manager's location, the contracting entity is in the UK for 25% of seats, Switzerland for 17%, the US for 14% and Germany for 11%, with Luxembourg, Asia-Pacific, Italy and South Africa behind. US groups often contract through a London or Dublin entity, so their true share is higher than the address suggests.

Who are the largest UCITS sub-advisory platforms in Europe?

The largest UCITS sub-advisory platform in Europe is Mediolanum, with $75.0 billion of sub-fund assets run by 68 outside managers. Banca Generali's LUX IM ($15.8 billion), Russell Investments ($14.9 billion), Lumyna ($14.2 billion) and Lombard Odier's PrivilEdge ($12.8 billion) complete the top five.

Source: Dakota analysis of CBI and CSSF registers and each umbrella's latest audited annual or semi-annual report, as of September 2026. Assets are sub-fund totals for sub-funds with at least one outside manager, converted to USD at ECB reference rates on each statement date. Same-group delegation is excluded.

1. Mediolanum

$75.0 billion with outside managers | 68 managers | 141 seats | Dublin

Mediolanum International Funds, the Dublin management company of Italy's Banca Mediolanum, runs the CHALLENGE Funds and Mediolanum Best Brands umbrellas. It is by far the largest sub-advisory buyer in Europe: on its own it accounts for 27% of the market's assets with outside managers.

What they outsource: Equities dominate. Global, international and sector equity mandates make up most of the 141 seats, followed by multi-asset and global bond sleeves. Of its 58 sub-funds with outside managers, 38 are split between two or more managers. That makes Mediolanum a buyer of sleeves inside blended funds as much as of whole funds.

Who runs money for them today: Wellington Management, Axiom Investors, AQR, J.P. Morgan Asset Management and Robeco, among 68 outside firms named in its June 2026 statements.

How they buy: Mediolanum's annual reports carry effective-date footnotes for each appointment and termination. Its 2025 and 2026 statements disclose 39 appointments, the most of any platform in this ranking, so the roster changes every half-year.

2. LUX IM (Banca Generali)

$15.8 billion with outside managers | 73 managers | 149 seats | Luxembourg

LUX IM is the Luxembourg SICAV of BG Fund Management Luxembourg, the asset management company wholly owned by Banca Generali. Together with BG Collection Investments, it gives Banca Generali's advisor network a range of third-party strategies under the LUX IM brand.

What they outsource: A balanced mix. Global equities, global bonds and multi-asset account for most of the 149 seats, and 40 of its 99 sub-funds use more than one manager.

Who runs money for them today: Morgan Stanley Investment Management, J.P. Morgan, BlackRock, Vontobel and Pictet Asset Management, among 73 outside firms, the most of any platform in the Top 10.

How they buy: Breadth over size. With 99 sub-funds, LUX IM hires for specific building blocks (short-duration credit, financials, EM debt) that suit specialist managers as well as large houses.

3. Russell Investments

$14.9 billion with outside managers | 66 managers | 120 seats | Dublin

Russell Investments is a global multi-manager, and its Irish umbrellas (Russell Investment Company plc, II, III and V, and Multi-Style, Multi-Manager Funds) are a direct European equivalent of US mutual fund sub-advisory. Carne Global Fund Managers is the host ManCo; Russell's own research team selects the managers.

What they outsource: Equities. Global, international and emerging market equity sleeves make up most of the 120 seats, with global real estate and small and mid cap mandates alongside.

Who runs money for them today: Acadian, Numeric, Invesco, Berenberg and Old Mutual Investment Group, among 66 outside firms.

How they buy: Russell blends several managers in a single fund. Its 2025 and 2026 statements disclose 27 appointments, so the roster turns over continuously rather than in one-off searches.

4. Lumyna (Generali Investments)

$14.2 billion with outside managers | 8 managers | 14 seats | Luxembourg

Lumyna was founded in 2007 under Bank of America Merrill Lynch and has been part of Generali Investments since 2018. Its Lumyna Funds platform brings third-party alternative and fixed income strategies into UCITS form through partnerships with outside managers.

What they outsource: Global and US bond mandates carry most of the assets, alongside liquid alternative strategies (absolute return credit, event-driven, diversified).

Who runs money for them today: Bridgewater Associates, BlueCove, HBK and MidOcean each run a named Lumyna sub-fund. BlackRock runs the large American, European and Asian debt sub-funds.

How they buy: Few seats, large tickets. With 14 seats behind $14.2 billion, Lumyna is the most concentrated buyer in the Top 10. It is the one to know for alternative and credit managers with an institutional-grade UCITS offering.

5. PrivilEdge (Lombard Odier)

$12.8 billion with outside managers | 35 managers | 39 seats | Luxembourg

PrivilEdge is the third-party fund range run by Lombard Odier Funds (Europe), the Luxembourg management company of the Swiss private bank. Each sub-fund carries the name of the manager that runs it.

What they outsource: Specialist building blocks across global bonds, US and international equities, EM and thematic equities. It is typically one manager per sub-fund.

Who runs money for them today: J.P. Morgan Asset Management, Robeco, William Blair, T. Rowe Price and Comgest, among 35 outside firms.

How they buy: PrivilEdge adds strategies one sub-fund at a time. Its March 2026 statements date five new appointments between October 2025 and March 2026.

6. Fideuram and Eurizon (Intesa Sanpaolo)

$12.8 billion with outside managers | 31 managers | 43 seats | Luxembourg

Fideuram Asset Management (Ireland), the Dublin ManCo of Intesa Sanpaolo's private banking arm, runs the Fonditalia, Interfund, Willerfunds and Fideuram Fund umbrellas. Eurizon Investment SICAV adds a further range. Delegations to Intesa's own Eurizon and Fideuram teams are excluded here.

What they outsource: Multi-asset and US equity mandates lead, followed by global bond and US fixed income sleeves.

Who runs money for them today: BlackRock, Fidelity International, Schroders and Pictet Asset Management each run a named Willerfunds "Private Suite" sub-fund, among 31 outside firms.

How they buy: Both routes are used. Some sub-funds are branded after the outside manager, and others, such as Interfund's US equity fund, blend several managers under the Intesa brand.

7. Architas (BNP Paribas Asset Management)

$11.8 billion with outside managers | 11 managers | 13 seats | Dublin

Architas Multi-Manager Europe is the Irish ManCo of the Architas Multi-Manager Global Funds Unit Trust. It was built inside AXA Investment Managers, which BNP Paribas acquired in July 2025. Its fund disclosures now sit with BNP Paribas Asset Management.

What they outsource: Global equities, Japan equities, global bonds and multi-asset. Several of its sub-funds are large mandates for Japanese investors, reported in yen.

Who runs money for them today: Capital Group, DWS, AllianceBernstein, Nomura Asset Management and Carmignac, among 11 outside firms.

How they buy: Large, single-manager mandates. Thirteen seats carry $11.8 billion, so each appointment is significant.

8. FAM Series (FinecoBank)

$11.8 billion with outside managers | 15 managers | 39 seats | Dublin

Fineco Asset Management, the Dublin ManCo of Italy's FinecoBank, runs the FAM Series UCITS ICAV. Many of its sub-funds pair an outside manager's name with the FAM brand.

What they outsource: Global bonds first (including emerging market debt), then global and US equities.

Who runs money for them today: M&G, Fidelity International, Nordea, Amundi and Schroders, among 15 outside firms.

How they buy: A relatively small group of large houses, each running several sub-funds: 39 seats across 15 managers.

9. NEF (Cassa Centrale Banca)

$11.7 billion with outside managers | 16 managers | 29 seats | Luxembourg

NEF is the Luxembourg UCITS umbrella of Nord Est Asset Management, owned since 2018 by Italy's Cassa Centrale Banca cooperative banking group. By design, NEAM entrusts the management of its sub-funds to outside managers.

What they outsource: Multi-asset (including target-risk and target-date sub-funds), US bonds and emerging market equities.

Who runs money for them today: Union Investment, Amundi, BlackRock, Candriam and Niche Asset Management, among 16 outside firms.

How they buy: NEF reviews its managers as a panel. In June 2025 it reorganised several equity mandates in one step, bringing in BlackRock and Fidelity International.

10. Pacific Asset Management

$7.7 billion with outside managers | 7 managers | 12 seats | Dublin

Pacific Asset Management is a London firm that builds UCITS funds in partnership with specialist managers, under the Pacific Capital UCITS Funds umbrella. Waystone is the host ManCo.

What they outsource: Global bonds, global and EM equities, and liquid alternatives, with one partner manager per sub-fund.

Who runs money for them today: North of South Capital, Coolabah Capital, Guinness Asset Management and Fulcrum Asset Management.

How they buy: Partnerships rather than panel searches. Pacific launches a fund around a manager it wants to back, which suits boutiques without their own UCITS range.

What about host ManCos like Carne and Waystone?

Host ManCos carry the regulatory licence for umbrellas that other firms promote. Third-party ManCos account for 911 seats, 45% of the total, and $79 billion of assets with outside managers. Carne ($22.0 billion) and Waystone ($16.5 billion) are the largest. For a fundraiser, the promoter is usually the decision-maker; the host signs off.

Host ManCo figures include umbrellas whose promoter also appears in the Top 10, such as Russell (Carne) and Pacific (Waystone).

Hosts matter to fund managers in two ways. First, some host platforms, such as Waystone's MontLake, are themselves a route to market for managers who want a UCITS without building a ManCo. Second, a host's roster shows which promoters (private banks, wealth managers and family offices) are running outside-managed UCITS ranges, and those promoters are the buyers to approach.

How concentrated is the market?

The UCITS sub-advisory market is highly concentrated. The ten largest selector platforms hold $188 billion, or 67% of the $280 billion with outside managers, and the 20 largest platforms and host ManCos hold 86%. Mediolanum alone accounts for 27%.

Concentration cuts both ways. A small group of platforms decides most of the money, so a Top 10 relationship matters. But the long tail of 100+ smaller platforms and hosts, many of them private banks and wealth managers, runs its own searches, often for strategies the large platforms already fill.

How should fund managers approach these platforms?

Approach UCITS sub-advisory platforms the way they buy: by sleeve, by strategy and on their reporting cycle. The ten largest hold 67% of assets, and 81% of recent appointments were additions rather than replacements. Manager research teams recommend the hire and ManCo boards approve it.

Four practical steps:

1. Map the incumbents first. Each platform's annual report names who runs every sub-fund today. That tells you where your strategy fits and who you would displace.

2. Pitch the gap, not the replacement. Across the market, 81% of the appointments disclosed in 2025 and 2026 statements were additions: new sub-funds or new sleeves. Very few were straight replacements of an incumbent. Our analysis of UCITS hires and fires shows where seats open.

3. Know who decides. Manager research teams make the recommendation; ManCo boards approve it and remain responsible. See who picks the sub-advisor.

4. Pick your domicile battles. Ireland and Luxembourg hold almost equal assets but behave differently. Our Ireland vs Luxembourg briefing compares them.

Frequently Asked Questions

What is the largest UCITS sub-advisory platform in Europe?

Mediolanum is the largest, with $75.0 billion of sub-fund assets run by 68 outside managers across its CHALLENGE Funds and Mediolanum Best Brands umbrellas in Dublin. That is 27% of the $280 billion of European UCITS assets with outside managers (Dakota analysis, September 2026).

How big is the European UCITS sub-advisory market?

Industry estimates put sub-advised UCITS assets across Europe at around $1.5 trillion (€1.4 trillion) as of 2023, including delegation within the same group. Dakota's filings-based map of Ireland and Luxembourg counts $280 billion of sub-fund assets run by outside managers that an external firm can compete for.

How many UCITS platforms use outside sub-advisors?

Dakota counts 125 platforms and management companies in Ireland and Luxembourg that delegate to outside managers, covering 341 umbrellas, 1,593 sub-funds and 2,036 seats. About 850 investment firms hold at least one of those seats.

What is the difference between a selector platform and a host ManCo?

A selector platform, such as Mediolanum or Fineco, builds its own-branded fund range and chooses the outside managers. A host ManCo, such as Carne or Waystone, carries the regulatory licence for umbrellas promoted by other firms, and the promoter usually chooses the manager.

Do US managers win European sub-advisory mandates?

Yes. Where the filings state the manager's location, US entities hold 14% of seats, and many US groups contract through a UK or Irish entity instead. UK managers hold 25% and Swiss managers 17%, so the channel is open to managers from any country.

Do UCITS platforms run public RFPs for sub-advisors?

Rarely. Most appointments surface in filings only after they happen, through the platform's annual or semi-annual report. Dakota's data is built from those filings, so it shows appointments and terminations rather than open searches, with a lag of a few months.

Which strategies do European platforms outsource most?

By number of seats, multi-asset (500), global equities (359), global fixed income (262), international equities (217) and sector equities (146) lead, followed by US fixed income, liquid alternatives, US equities and emerging market equities.

How was this ranking built?

Dakota read the CBI and CSSF registers and the latest audited statements of every umbrella that names its delegates. Platforms are ranked by the total assets of sub-funds with at least one outside manager, converted to USD. Same-group delegation and host ManCos are excluded from the ranking.
