The Evolving Wealth Management Landscape and the Rise of Outsourced Services

Growth in the Wealth Management Industry

Over the past decade, the wealth management industry has undergone strong and sustained expansion, driven by rising global wealth, favorable market performance, and increased investor engagement. Global financial wealth reached $305 trillion in 2024¹, growing more than 8% in that year alone, supported by robust equity markets and broadly positive investor sentiment.

Advisory industry assets under management (AUM) also climbed, reaching an estimated $159 trillion in 2024, a 20% increase over the past five years and the continuation of a decade-long upward trajectory². Notably, only 28% of global AUM growth³ over this period stemmed from organic client acquisition; the majority was fueled by market appreciation, adviser hiring, and consolidation. Despite these dynamics, the long-term outlook remains strong, with total investable wealth expected to exceed $481 trillion by 2030⁴.

Regulatory Shifts

In 2014, the SEC clarified through enforcement actions that hypothetical performance would be considered an unsubstantiated claim unless supported by proper due diligence and clear disclosure. These guidelines were further formalized with the SEC Marketing Rule, effective in 2021. This established requirements for substantiation, enhanced books and records, and considerations for the appropriateness of the audience. Within these updated provisions, there were also new considerations for the use of representative account performance and related account performance.

For Turnkey Asset Management Platforms (TAMPs) and marketplaces, the Marketing Rule has led to stricter onboarding procedures, stronger model governance, and ongoing oversight. This also may result in increased scrutiny of marketing materials, more rigorous compliance reviews, and the necessity for platforms to provide transparent disclosures to both advisers and clients, ensuring that all performance claims are fully supported and compliant with regulatory standards.

How the TAMP Landscape Has Evolved

TAMPs have transformed from niche outsourcing tools into core engines of adviser scalability. By 2025, industry estimates place total TAMP managed assets near $3 trillion⁵, reflecting a major shift toward outsourced portfolio management. Adviser engagement has grown sharply: 45% of advisers now use at least one TAMP, an increase from roughly 10% ten years ago⁶.

Parallel growth in model portfolios is accelerating this trend. Adviser-managed model portfolios accounted for 13% of assets in 2023 and are projected to reach $2.9 trillion by 2026, a nearly 40% increase⁷.

Performance numbers from leading TAMPs reinforce this momentum:

• AssetMark reported 21.5% YoY asset growth to $116.9B in Q1 2024⁸.
• Envestnet achieved 16% YoY growth in recurring asset-based revenue and $12.5B in net flows (12% annualized organic growth)⁹.
• Emerging platforms like GeoWealth posted approximately 26% annualized growth (2021–2024)¹⁰.

Collectively, these trends reflect a market increasingly reliant on open architecture, scalable operational models, and technology-enhanced investment solutions.

TAMP Onboarding and Requirements

TAMP onboarding requires both operational readiness and regulatory discipline. Platforms typically review:

• Organizational structure, regulatory status, key personnel, and governance
• Compliance policies, codes of ethics, business continuity plans, and insurance
• Strategy documentation, GIPS-aligned performance records, and methodology transparency
• Technology integrations, data delivery workflows, and cybersecurity controls
• Risk management protocols, reporting standards, and operational resilience

Performance substantiation, including:

• Full performance calculation methodology
• Benchmarking logic and rebalancing assumptions
• Backtest documentation with required hypothetical performance disclosures
• Independent variance testing
• Signed strategist attestations

Entering the onboarding process with clean documentation, well-defined processes, and integration-ready systems significantly accelerates approval timelines. Firms considering a TAMP partnership should use a structured readiness checklist, such as the one below, to ensure they can meet the operational, regulatory, and performance substantiation standards required by today’s leading providers.
