Key Takeaways
Most ETF distribution teams are built to reach financial advisors one at a time. That made sense when advisors picked funds one at a time. They increasingly do not. Third-party model portfolio assets reached $943 billion as of the end of March 2026, and the average model now allocates 55.4% of its assets to ETFs. When a strategist adds your fund to a model, the allocation propagates across every practice running that model, without a single wholesaler meeting.
That shifts where distribution power sits. The buyer is no longer only the advisor; it is the home-office analyst, the investment committee, and the third-party strategist who decide what goes in the model. We built our intent data practice around identifying exactly this kind of high-value, hard-to-reach decision-maker inside financial services firms. This post explains who the gatekeepers are, what they screen for, and how to market to a committee rather than an individual.
Why Are Model Portfolios Now the Highest-Value ETF Distribution Channel?
Model portfolios concentrate allocation decisions. Instead of persuading 500 advisors individually, an issuer persuades one investment committee whose model those advisors run. Third-party model assets hit $943 billion as of March 2026, a 46% increase year over year, and took in $42.6 billion of net inflows in the prior year. Each inclusion decision carries the weight of thousands of downstream portfolios.
The vehicle mix inside those models has also moved decisively toward ETFs. According to Morningstar's 2026 US Model Portfolio Landscape, which combined survey data from 32 providers with regulatory filings from more than 50 others, ETFs now represent 55.4% of average model assets against 34% for mutual funds and 8.2% for individual stocks.
The tradeoff is cycle length. Model inclusion takes far longer than an advisor conversation and involves more stakeholders, so it works as a parallel motion to advisor coverage rather than a replacement. Issuers that reassign wholesalers away from advisor relationships to chase model inclusion typically lose near-term flows before the model pipeline matures.
Who Actually Decides Which ETFs Enter a Model Portfolio?
Three distinct groups control model inclusion, and they screen differently. Home-office due diligence analysts at wirehouses and large broker-dealers maintain approved lists. Third-party strategists build models sold across multiple platforms. Investment committees at large RIAs construct proprietary models for their own advisors. Marketing that treats all three as one audience fails with all three.
Their mandates differ. A home-office analyst protects a firm against fiduciary and reputational risk across every client account. A third-party strategist competes commercially against other strategists and needs building blocks that improve their own model's profile. An RIA investment committee sits between the two, with fiduciary duty but far less bureaucracy.
Cerulli's Matt Apkarian framed the implication directly in a September 2024 analysis that projected asset allocation model assets would reach $2.9 trillion by 2026:
"Asset managers not currently targeting inclusion in model portfolios as a method of distribution for their investment products should assess how they can best target the growing model landscape as a distribution channel."
What Do Home-Office Gatekeepers Screen For Before an ETF Gets Approved?
Gatekeeper screens are elimination-first. Most funds are removed on mechanical criteria before anyone evaluates strategy: insufficient operating history, assets below a platform minimum, thin secondary-market liquidity, or an expense ratio that is uncompetitive within its category. Strategy quality only gets evaluated after a fund clears those thresholds.
This sequencing is the most useful thing for a marketing team to understand. Messaging built entirely around strategy differentiation aims at the last stage of a process most funds never reach. If your fund has a gap on a mechanical screen, the marketing job is to address that gap directly, not to argue harder about strategy.
State Street's intermediary research on ETF due diligence documents the same progression, with index objective alignment, issuer reputation, and structural liquidity as core criteria. SEC duty-of-care expectations require a documented process, which is why these decisions tend to be conservative and slow rather than opportunistic.
One constraint: this sequence describes platforms with formal due diligence functions. Smaller RIA committees compress these stages considerably, which is why emerging issuers frequently win their first model inclusions at independent RIAs rather than wirehouses.
How Should ETF Marketing Change When the Buyer Is a Committee?
Committee marketing optimizes for the internal advocate, not the initial reader. Someone inside the firm has to carry your fund through a multi-stage review and defend it to colleagues. Advisor marketing rewards narrative and timeliness; gatekeeper marketing rewards documentation, meaning methodology detail, tracking data, capacity analysis, and clean answers to predictable diligence questions. A commercial flyer is nearly useless in a due diligence meeting.
Four rules follow. Build for the memo, assuming every asset gets excerpted into a document written by someone else. Answer the elimination screens explicitly, because silence on a known weakness reads as evasion to an analyst whose job is finding weaknesses. Track engagement at the firm level, since committee interest surfaces as multiple people from one firm researching the same fund in a short window, the same principle behind identifying when high-intent advisors cluster in a single office. And respect the calendar, because materials arriving after a quarterly review wait a full quarter for attention.
How Do You Identify Which Firms Are Actively Evaluating Your Fund?
Gatekeeper research activity is observable before any inbound contact happens. Analysts read fund pages, pull methodology documents, and compare competitors well before they reach out. Firms that identify this behavior can engage during evaluation rather than after a decision. Defiance Analytics campaigns average 82.8% open rates across 21,795 sends by reaching verified decision-makers at the moment of active research.
Three signals matter more than the rest. Repeat visits from a single firm across multiple sessions indicate structured evaluation rather than casual interest. Multiple distinct people from one firm researching the same category in a short window suggests a committee process. Document-level engagement, particularly with methodology and holdings materials rather than marketing pages, indicates diligence rather than browsing.
Site traffic identification resolves anonymous research activity to firms, which is what makes clustering visible at all. Pairing it with CRD-indexed advisor tracking keeps identification accurate when individuals change firms.
One caveat applies. Intent signals show evaluation, not intent to approve. A firm researching your fund may be building a case to reject it, or comparing it against an incumbent it plans to keep. The signal tells you when to engage, not how it ends.
Conclusion
Model portfolios have moved from a distribution curiosity to a $943 billion channel where ETFs now hold 55.4% of assets. The decision-makers are home-office analysts, third-party strategists, and investment committees, each screening on different mandates and eliminating most funds on mechanical criteria before strategy is discussed at all. Marketing that treats them as advisors under a different name keeps losing at stage one.
The teams that win here build documentation rather than campaigns, address elimination screens honestly, and detect firm-level research early enough to join the evaluation. Our clients reach these decision-makers through firm-resolved intent data rather than broad advisor lists.

Frequently Asked Questions
How long does it take to get an ETF into a model portfolio? Model inclusion cycles run considerably longer than advisor sales cycles, often spanning multiple quarterly review periods because committees meet on fixed calendars. Home-office and platform decisions generally take longer than independent RIA committee decisions, which involve fewer stakeholders.
Do newer ETFs have any realistic chance of model inclusion? Yes, but usually not at the largest platforms first. Many home-office screens eliminate funds below track-record and asset thresholds before strategy review. Independent RIA investment committees apply these screens more flexibly, which is why emerging issuers often build their first model relationships there.
What is the difference between an approved list and a model portfolio? An approved list defines which funds advisors at a firm are permitted to use. A model portfolio specifies an actual allocation that advisors implement. Approved-list inclusion is permission; model inclusion is an allocation decision that moves assets directly.
Should ETF issuers market to gatekeepers and advisors differently? Yes. Advisor marketing optimizes for individual persuasion and timeliness. Gatekeeper marketing optimizes for documentation an internal advocate can carry through a multi-stage committee review. The same materials rarely work for both audiences.
Bottom Line
- Third-party model portfolios reached $943 billion as of March 2026, growing 46% year over year, with 55.4% of average model assets held in ETFs.
- Gatekeepers eliminate most funds on mechanical criteria, including track record, assets, liquidity, and cost, before strategy is evaluated at all.
- Committee buying produces firm-level research clustering, which is only visible to issuers measuring engagement by firm rather than by individual contact.
