Hedge Funds

The rumors of the resurgence of hedge funds may have been understated. The success of 2024 might not be a blip on the radar but instead a portent of good things to come. H1 2025 hedge fund allocations ($37 billion) spiked to the highest level since 2015; as hedge funds have delivered 11 consecutive quarters of positive returns.i The US Federal Reserve is not rushing to lower rates; US trade policy has risen to a new level of uncertainty; and geopolitical tensions now stretch from continent to continent.

In our recent article, we noted how the multi-strategy hedge fund model led all strategies in August, as Hedge Fund Research’s (HFR) index increased 7.5% in August 2025. Some assert that there is a growing gulf between the big and small funds, especially among multi-strategy or multi-manager platforms. August dispersion data — in which high performing funds grew by +10% and lower performing funds fell by -2.7% — and the recent shuttering of Eisler Capital seems to support the idea that multi-strategy funds must scale to survive in today’s environment.ii

The successful scaling of hedge funds, as well as most other buy-side firms, emerged as a universal challenge, thanks to digital transformation waves that legacy investment systems struggle to integrate. The AI revolution is the latest pressure point exerting change in terms of both increased technology spending and systems integration. It also marks an inflection point in operational models, which if used well, represents a major positive force in terms of personalization, efficiencies, and scaling the business. Here are practical ways that AI is powering the next wave of multi-strategy hedge fund growth and helping the scaling of their complex models for competitive edge, including multi-manager platforms.

Spotlight on the portfolio manager (PM)     

The hedge fund talent war has been well-documented, and some say it is a “full-blown arms race for alpha.”iii There are bidding wars and $100 million compensation packages, while at the same time multi-manager platforms are demanding performance, some installing hard stop-loss thresholds. A BlackRock executive told Spears Magazine that in the current environment, there’s a widening gap between good managers and average ones, and “if you can identify those good managers, there’s more potential reward than in the past.”iv Therefore, PMs are under the microscope, both in terms of keeping them happy and retained and also tracking their performance and overseeing risk exposures.

Technology-forward PMs want AI

Savvy young PMs expect their firms to give them the tools they need to succeed. They do not want to chase other departments or IT to get data they need; they do not want to work in a place where they cannot trust the integrity and accuracy of data; and they expect their firms to be deep into the development of AI agents. They will jump quick if they bump up against operational barriers to their day-to-day business of driving alpha. PMs, as well as other departmental staff, will soon be using AI agents to execute key tasks. They already can use natural speech with AI to navigate searchable data catalogs to find and track data assets — in a fraction of the time they used to expend.

This is made possible by automated data management processes working in the background, in which AI-powered data quality and governance engines ensure insights are up to date, precise, and easy to understand. Moving a step farther, AI will be helping to not only gain swift access to the right information but also add depth and speed to financial analysis, making it even easier to surface actionable insights.

AI for intelligent multi-strategy operations

Arcesium’s Aquata platform includes AI capabilities that solve the perilous problem of dealing with unstructured data. It can ingest and harmonize diverse, previously unusable information from documents like PDFs that contain valuable business intelligence. For example, managers and analysts can use unstructured proxy vote data, consumer loan terms, and capital call notices data to inform their governance quality screening, relative value/arbitrage strategies, or liquidity timing and stress signals, respectively. And in doing so, they incur fewer errors and can scale without sweating about adding large or unwieldy datasets. Business users can ask natural language questions about their data and have the AI generate the relevant visualizations like graphs, charts, and dashboards automatically.

The Opterra platform unlocks efficiencies for operational users, and our agentic AI capabilities will soon be helping human colleagues execute tasks across the investment lifecycle like trade processing, reconciliation, and collateral management. In the first part of our two-part series on multi-strategy funds, we noted that tools like universal book of record (UBOR), an innovative combination of IBOR and ABOR, help funds thrive in complex multi-manager structures, offering them separate strategy views, allocations, and performance, allowing them to extend capital to the best strategies and asset classes.  

Funds with benefits: make the most of the multi-manager model

A major benefit of the multi-manager hedge fund structure is its capability to gain capital deployment and margin efficiencies with the diversification of managers and strategies. However, if the fund accountant is unable to accurately track that across the different PMs, that would-be benefit becomes an operational albatross. If you're running a highly diversified overall portfolio, then you need to capture where you're gaining those efficiencies to justify the multi-manager approach. Armed with the advantage of an accurate and speedy house view into the fund’s liquidity and cash flow, as well as fully loaded P&Ls of each manager and portfolio, managers ensure optimal allocations to the best-performing PMs and strategies and subsequently can generate margin efficiencies.

AI-powered real-time reporting and risk transparency

The precise tracking of sophisticated P&L allocations and structures across all portfolios empowers managers to produce real-time risk reports that help better manage liquidity and counterparty risk. The Aquata data platform’s AI-powered, self-service financial data analysis tools help funds slice and dice data, personalize and visualize reports, and automate and schedule delivery of client, regulatory, and management reports.

The Aquata data platform offers out-of-the-box partner and vendor integrations with OMS, trading systems, execution venues, and market data vendors. Upcoming AI capabilities will further accelerate data integration by automatically detecting schemas, generating custom data models, and building intelligent data pipelines. Armed with a deeper well of investment data, PMs can react deftly when market changes require quick pivots.

Resources for Portfolio Managers

“With the present-day systems, portfolio managers typically lack the resources to perform the cumbersome task of analyzing underlying assets from third-party sources, such as managers of funds of funds or ETFs, more often than two or three times a year. AI, however, can quickly detect and analyze that data.”

The ultimate edge: scale, speed, and smart allocation

Arguably the ability to scale operations along with AUM is the preeminent challenge of the modern buy-side investment firm. Their data infrastructure must be flexible enough to process enormous, disparate datasets; and operational systems must be pliable while retaining integrity. For high-volume business segments, AI can help automate manual trade capture and manage increased volume from systematic or algorithmic managers, addressing scaling concerns. Additionally, as millions of individual retail investors gain their first access to alternative investments, BNY Mellon notes that managers are finding new ways to attract retail investors and are being creative in how they structure investment opportunities, including multi-manager products that let them access multiple strategies in a single fund.vi

Further, using a multi-manager platform or multi-asset strategy, a fund will often need to onboard new managers and portfolios — and do so rapidly. In a fund where data ingestion and data pipeline building is an onerous task involving several departments, delays can break the spirit of even the most enthusiastic managers.

Scaling the multi-manager model for competitive edge

The multi-manager hedge fund model has seen increased interest and growth due to its ability to provide access to many different strategies at once and attract large capital allocations. The big multi-strategy shops are so busy that some are closed to new investors. Speed to market and ability to scale are perhaps the most prized competitive advantages in this era of sophisticated financial products, vehicles, and structures. AI-driven fund operations and efficiencies are center stage for multi-strategy and multi-manager hedge funds as we dive into the last quarter of 2025.

Our recent survey report in collaboration with Hedgeweek found that 42% of multi-strategy hedge funds have implemented AI in multiple or limited areas.vii Recent research suggests that hedge funds leveraging AI achieve 3-5% higher annualized returns compared to nonadopters, with the most significant benefits in equity hedge strategies.viii AI tools are powerful for automation, efficiency, cost reduction, and scale.
