The U.S. TAMP market now represents approximately $3 trillion in platform assets, and advisor adoption has climbed from roughly 10% to approximately 45% over the past decade… a ~16% annual growth rate sustained across a full market cycle. (Wealth Advisor, America's Best TAMPs 2025)
For investment firms, that number tells a specific story: the RIA and broker-dealer channels are being accessed through a small number of platforms, not through direct advisor relationships alone. Which platforms you're on, and how well you show up on them, now shapes your distribution reach as much as your investor relations team does.
Our full TAMP market report breaks down the complete picture.
In this post, we’ll focus on what the data means for investment firms trying to access the advisor channel.
Private Equity Already Figured This Out
The clearest signal that TAMPs have become distribution infrastructure (not back-office plumbing) came in 2024. Bain Capital took Envestnet private for approximately $4.5 billion. GTCR took AssetMark private for $2.7 billion. Both in the same year.
These are not distressed asset plays. They are conviction bets on scalable, recurring-revenue businesses with deep advisor distribution networks. The buyers understood something that many investment firms are still catching up to: whoever controls the platform controls access to tens of thousands of advisors.
The largest platforms today each manage over $100 billion in assets (Wealth Advisor, America's Best TAMPs 2025), with Envestnet, SEI, AssetMark, and Orion each operating at that scale. The TAMP market is dominated by a small number of scaled players, and that list is getting shorter as consolidation continues.
Where the Channel Is Actually Concentrated
Dakota Marketplace has identified TAMP platforms used by 6,400+ accounts representing $46T+ in advisor firm AUM. The AUM breakdown is the part that matters most for distribution strategy:
- 69% of TAMP users manage under $500M in AUM
- 81% of TAMP users manage under $1B in AUM
The TAMP channel is a small-to-mid RIA story not a mega-RIA story. These are thousands of practices that rely entirely on platforms for portfolio construction, manager access, and operational infrastructure. They are not running independent manager searches. They are allocating through what the platform offers.
For investment firms, that changes the distribution math entirely. Direct coverage of thousands of sub-$500M RIAs is not a realistic model. Getting onto the platforms those firms run on is the way to go.
The Three Platform Categories Investment Firms Need to Understand
Not all TAMPs serve the same function for investment firms. The market breaks into three meaningful categories:
|
Platform Type
|
Key Players
|
Primary Function for Investment Firms
|
|
Full-Service TAMPs
|
Envestnet, SEI, AssetMark, Orion
|
Model portfolio inclusion, broad advisor distribution
|
|
Alternatives-Focused
|
iCapital, CAIS, GLASfunds, SUBSCRIBE
|
Private markets access, subscription workflows
|
|
Specialized / Emerging
|
GeoWealth, Vestmark, SMArtX
|
Direct indexing, tax optimization, open architecture
|
Full-service TAMPs are the broadest distribution gateway, inclusion in their model portfolios reaches advisors at scale without direct contact. Alternatives-focused platforms are becoming essential for private markets managers, as they handle the subscription, capital call, and reporting infrastructure that makes alternatives accessible to advisors. Specialized platforms are worth tracking for investment firms targeting RIAs with specific portfolio construction needs.
The critical distinction: being available on a platform's marketplace is not the same as being included in a managed model portfolio. Marketplace presence drives awareness. Model portfolio inclusion drives asset growth. For most investment firms, model inclusion is the primary goal.

Why This Is Accelerating
Two developments are pushing TAMP distribution from important to essential for investment firms.
First, platform consolidation is reducing the number of meaningful distribution relationships. As larger TAMPs acquire smaller ones and adjacent technology providers, the advisor base concentrates further. A platform that reaches 50,000 advisors today may reach 80,000 after the next acquisition. The platforms that scale become more important gatekeepers, not less.
Second, alternatives access is becoming standard on major TAMP platforms. Fidelity and Envestnet have introduced turnkey model portfolios incorporating private equity, private credit, and private real estate at scale. iCapital, GeoWealth, and BlackRock have partnered to deliver custom private asset models combining private markets, direct indexing, and fixed-income SMAs into a single UMA structure. For private markets managers specifically, TAMP platforms are no longer a niche distribution channel. They are a primary one.
Start With the Platforms, Not the Advisors
TAMPs have evolved from operational outsourcing tools into the core infrastructure layer of the advisor channel. For investment firms, that means TAMP relationships belong in the same category as consultant relationships and direct allocator development.
The firms building platform-ready products and operations now will have a structural distribution advantage as advisor adoption continues to climb. For a broader view of where the RIA market is heading, see our analysis of the top trends defining the RIA market in 2026.
