In 2025, hedge fund managers were faced with a new federal administration and new SEC Chair Paul S. Atkins. The effects of those changes in leadership are still being felt and may accelerate in 2026. To that end, the Hedge Fund Law Report spoke with Simpson Thacher partners Adam S. Aderton and Anne C. Choe about the key legal and compliance developments in 2025, what hedge fund managers may expect from the SEC in 2026 and what CCOs should focus on to prepare for the new year. This article presents their thoughts on those topics.
For additional commentary from Aderton, see “SEC Penalizes Fund Administrator for Missing Red Flags” (Jul. 18, 2024); and “Recent SEC ESG Rulemaking, Examination and Enforcement Activity” (Mar. 30, 2023).
2025 in Review
HFLR: What were the key legal and compliance developments that hedge fund managers faced in 2025?
Choe: One noteworthy item is that the SEC Division of Examinations released its 2026 exam priorities in November 2025. It was actually a bit surprising that they did not have a separate private fund section, potentially signaling a decreased emphasis on private funds. But, in our experience, examiners routinely look at core topic areas that cover hedge fund managers, such as marketing, valuations, trading and portfolio management. So we think hedge fund managers should continue to remain vigilant on those core issues.
[For more on the 2026 exam priorities, see “Compliance Corner Q1‑2026: Regulatory Filings and Other Considerations Hedge Fund Advisers Should Note in the Coming Quarter” (Dec. 18, 2025).]
We also saw continued growth throughout 2025 of hedge fund strategies being brought to the market in retail wrappers, such as exchange-traded funds, business development companies and other SEC-regulated products. There’s a broader retailization movement that definitely occurred in 2025, and we expect that to further accelerate in 2026.
Aderton: I’ll layer on one more significant legal or compliance development – the postponement of the compliance deadlines for several significant final rule changes that would have affected hedge fund managers: Form PF amendments, short sale reporting and securities lending. Those deadlines were extended, either following a court action – in the case of short sale reporting and securities lending – or on the Commission’s own volition, as to Form PF. That’s consistent with the SEC’s desire to take a fresh look at a number of rules that were adopted in the prior administration.
HFLR: What’s likely to happen to those final rules you mentioned?
Aderton: Taking Form PF as an example, the current majority of the SEC commissioners has historically been somewhat critical of continued expansion of Form PF, and the most recent Form PF amendments that were put on pause would have been a further expansion. We’ve heard Chair Atkins talk about things like the minimum dose of necessary regulation to achieve the Commission’s aims. So if these Form PF amendments ever do take effect, we are likely to see them scaled back to whatever this current iteration of the Commission thinks is actually necessary for it to effectively regulate the market as it sees fit. Thus, one takeaway is that there may be an overall reduction in the number of obligations that are going to come along with, say, Form PF – and the same will be true with short sale reporting and securities lending.
Choe: Yes, we anticipate potential amendments to Form PF. In fact, in an open meeting on the postponement of the compliance date, Atkins specifically noted that he has directed the staff to further evaluate any appropriate action and the Division of Investment Management to consider whether those changes are achieving the goals the form was originally intended to address.
[See “Third Round of Form PF Amendments Focuses on Granular Hedge Fund Data (Part One of Two)” (Jun. 6, 2024).]
HFLR: What about the pending rule proposals that were released under former SEC Chairman Gary S. Gensler that have also been paused under Atkins, such as the cybersecurity rules for investment advisers; the environmental, social and governance (ESG) disclosures; and the revised Custody Rule, which the SEC renamed the Safeguarding Rule. Will those ever see the light of day in some form or are they dead at this point?
Choe: We aren’t anticipating that the ESG rules will go forward, so that’s likely dead. But we are expecting potential amendments to the Custody Rule, which was included on the latest Reg Flex agenda as a regulation that could potentially be amended or modernized to address, for example, crypto assets.
[See “The SEC’s Proposed Safeguarding Rule: Significant Implications for Private Fund Managers” (Apr. 27, 2023).]
Aderton: I don’t think we’ll see the cybersecurity rules and the other proposals again. If you read the statements of the SEC commissioners who are currently in the majority, but were in the minority at the time of the proposals, it’s clear that, in many cases, they did not think the rule proposals were necessary or were solving a problem in the market that existing rules couldn’t reach. So anytime you see a historical statement like that about a proposal, it’s unlikely to be reproposed.
[See “SEC Proposes Cyber Risk Management Rules for Advisers” (Mar. 24, 2022).]
HFLR: Talking about the SEC in general, how would you describe the overall changes at the SEC in terms of its operations and priorities?
Aderton: To me, the biggest change is related to the agency’s personnel. They’ve publicly disclosed that the agency has gone from somewhere north of 5,000 staffers to something closer to 4,000 – and there may be additional reductions in the future. Those cuts necessarily make it a little bit more challenging for them to do as many things. So although the SEC has always been resource constrained, that is more acutely felt now, such that it’s going to have to think carefully about what aspects of its operations to prioritize. Due to that, one big thing that will come out of 2025 is that the SEC’s ability to be in as many places at the same time will be somewhat limited.
Another thing is a complete reversal of the SEC’s position on cryptocurrency. A lot of its prioritization is probably going to go toward the ability to bring crypto into the overall regulatory environment.
Operationally, the SEC is really focused on facilitating innovation and thinking creatively about ways to promote it. That’s something that could be beneficial to hedge fund managers that think innovatively about ways to expand and enhance their businesses. This is an SEC that has been very clear that it wants to hear ideas about how the regulatory environment could be shaped to facilitate that innovation and capital formation.
Choe: The only thing I would add to the innovation point is the growth of more private equity (PE) and hedge fund managers exploring retailization, as well as additional investment strategies they may not have pursued historically, including more private credit and direct lending. And as part of innovation by the SEC, there may be more targeted rulemaking in that area. But the SEC is also open to hearing ideas around additional staff guidance, FAQs and no-action relief, which may promote innovation.
HFLR: There has been criticism, including by some of the current commissioners, of the perceived practice of “regulation through enforcement” under Gensler. Do you think we’ve seen the end of that approach under Atkins?
Aderton: The short answer is yes. I expect that they will bring cases when, in their view, the lines are clear in terms of what is permissible and what is violative conduct. When the lines aren’t clear, we’re likely to see things like staff guidance or similar statements coming out of the Commission, rather than the pursuit of enforcement actions as the mechanism to advance new or broadening interpretations of existing regulations.
Choe: That recently occurred when, on December 16, 2025, the Division of Examinations released a new risk alert on deficiencies examiners found in connection with the Marketing Rule. So that’s an example of when they decided to issue a risk alert around those findings in lieu of pursuing enforcement actions.
HFLR: Under Gensler, the SEC issued very little guidance, and, frankly, the guidance that did come out wasn’t particularly helpful. Do you see the new SEC being more open to releasing that sort of guidance, which CCOs and the like really appreciate?
Choe: That’s a great observation. We do anticipate additional guidance and FAQs. We know the staff is reaching out to the industry and having meetings to talk about additional FAQs as to the Marketing Rule, as well as potential rulemaking in advance of actual putting pen to paper on proposed rules. So there has definitely been a push for more engagement between the SEC staff and the industry.
[See “What Hedge Fund Managers May Expect From the SEC in 2025” (Jan. 16, 2025).]
Cryptocurrency and Tokenization
HFLR: You’ve both mentioned cryptocurrency. This SEC has done a complete 180 from the prior leadership on digital assets. What are the implications for hedge fund managers specifically, and the private fund space in general, of the SEC’s embrace of cryptocurrency under Atkins?
Aderton: I was at the SEC through part of Gensler’s term and through the prior approach to crypto. The takeaway is that this Commission is very committed to establishing a system of regulation that incorporates crypto into the existing financial regulatory system. Part of that is going to have to be done by Congress, but the part that the SEC can do, it seems committed to doing.
So for hedge fund managers that were concerned about the uncertainty of the regulatory approach to crypto in the last administration, that concern and the likelihood of enforcement is much diminished. In instances in which cryptocurrency intersects with some type of fraud, the Commission has said that it’s going to bring those cases. But I don’t think that was the concern for a lot of managers under the prior administration. They were more worried about registration and reputational concerns then, and those concerns are on the shelf through the end of this Commission.
Choe: I would just add that the Simpson Thacher team obtained a no‑action letter right before the government shutdown that actually helped pave the way for managers, including hedge fund managers, to be more comfortable investing directly in spot crypto. And we are already seeing some managers pursue this strategy when, historically, they have not because of Custody Rule concerns.
[See “NSCP to SEC’s Crypto Task Force: Focus on Clarity, Custody and Coordination” (Nov. 20, 2025); as well as our two-part series on an SEC Crypto Roundtable on custody of digital assets: “Custody Challenges” (Jun. 5, 2025); and “Custody Models” (Jun. 19, 2025).]
HFLR: The SEC may have embraced cryptocurrency, but it’s not the only regulator with a stake in that world. The CFTC also has some claims on regulating cryptocurrency. Do you think the two agencies will be able to work together to figure out how best to put crypto regulations in place?
Choe: The head of the CFTC is Michael Selig, who was previously on the SEC’s Crypto Task Force. So I think there will be close collaboration and cooperation between the SEC and CFTC in this area.
HFLR: You mentioned innovation, which brought to mind the idea of tokenizing interests in hedge funds. The SEC seems to be open to the idea of tokenization. If so, will more hedge fund managers embrace that approach?
Choe: I think the SEC is open to exploring innovation, including tokenized products. We are already seeing tokenized fund shares being developed and evolving significantly even just in the past year or two. And we are continuing to have discussions with clients around tokenized fund shares. So this is going to be a really exciting and developing area.
Aderton: I completely agree and see tokenization as one area that, across the investment adviser broker-dealer ecosystem, firms believe there are real opportunities for efficiencies. So I think this is going to be vigorously pursued over the next couple of years.
[See “Project Guardian Report Addresses Tokenization in Asset Management” (Dec. 5, 2024); “Benefits and Challenges Associated With Tokenization of Assets” (Apr. 25, 2024); as well as our two part-series on tokenization on the blockchain: “Unique Challenges and Benefits and Its Use by Hedge Funds” (May 27, 2021); and “Applicability to Private Debt and the Technology’s Future Outlook” (Sep. 30, 2021).]
Retailization
HFLR: What other aspects of innovation should we discuss?
Aderton: To me, the other really big one is around retailization, which Anne already touched on a little bit. I see fund managers looking for ways to facilitate the dissemination of private fund strategies, including hedge fund strategies, through retail-type products.
HFLR: Is the SEC’s interest in retailization – and generally making private markets more available to retail investment – geared more toward PE funds and less toward hedge funds?
Choe: That’s a fair characterization, but we are seeing a convergence in the strategies that more traditional hedge fund managers pursue. For example, they are pursuing less liquid strategies like private credit and direct lending, and those types of strategies will likely be involved in retailization conversations.
Another development in this area is President Trump’s executive order directing regulators to examine how alternative assets can be incorporated into 401(k) plans. We anticipate that both PE and hedge fund managers will be part of that broader conversation. For example, an interval fund could be included as an investment option for a target date fund for which a hedge fund or private credit manager could manage either the liquid or less liquid credit strategies.
HFLR: Is there a lot of interest in retailization in the hedge fund space? Are managers willing to tackle the associated challenges in exchange for having access to a new pool of capital?
Choe: It’s a mixed bag. There are certainly managers that have expressed interest in retail and others that have not. We are seeing both.
HFLR: Are managers hesitating in the hope that some of those barriers or challenges will be minimized or alleviated by the SEC to promote retailization?
Choe: That’s right. Although with the growth of new strategies, new products and retailization, we are still expecting the SEC to pay attention and conduct examinations in these areas – particularly if there are allegations of misconduct. We’ve already seen an increase in examinations of interval funds and their sponsors, including alternative asset managers.
[See our two-part series on the retailization of private funds: “Incremental Changes Signal SEC Support” (Aug. 14, 2025); and “Practical Consequences” (Aug. 28, 2025); as well as “Advances and Challenges in ‘Retailization’ of Alternative Investment Products” (Jun. 19, 2025).]
Artificial Intelligence
HFLR: It feels like, in the last year, the use of artificial intelligence (AI) by basically every industry has skyrocketed. Have you seen hedge fund managers jumping on that bandwagon by using AI, and, if so, in what ways are they using this technology?
Aderton: Yes. We’ve seen increased implementation and use of AI across hedge fund managers’ businesses. Some of it is the way that many other businesses are using AI – i.e., to facilitate meetings, write first drafts, etc. But hedge fund managers are some of the most sophisticated users of technology in the financial markets. In my experience, a lot of them have been using machine learning and other forms of AI for a considerable period of time now. The most recent AI boom is enhancing and accelerating those efforts that were already ongoing.
Most managers are thinking about all the areas across their firms that they can safely and compliantly deploy AI to improve their performance and make their business more efficient. So we saw an uptick in 2025, and I think we will continue to see significant additional deployment in 2026.
HFLR: I get the sense you think the hedge fund space may have been a little bit ahead of the curve compared to other industries in terms of adopting AI.
Aderton: That’s my perception. A lot of hedge funds have quantitative strategies, or, even to the extent they have fundamental strategies, they are running complex modeling for which AI can be beneficial. So, compared to many industries, hedge fund managers were probably further down the path than some others.
HFLR: What about the use of AI by the SEC itself? Is the SEC using AI internally? If so, in what ways? And do you expect that to continue?
Aderton: I know that the SEC publicly disclosed that it has an AI Task Force, which is intended to look at the ways the SEC can use AI for its own operations. Given that announcement, I expect that the SEC is deploying AI in some ways internally and will be looking for opportunities to continue to expand that deployment. It also dovetails nicely with the fact that it has experienced staff reductions, so I’m sure it’s looking for efficiencies and work that AI can do that may have been done by staffers historically.
Choe: The other point I would make is that the SEC is a disclosure-based regulator. It’s a very data-rich environment – the exact type of environment that could potentially benefit a lot from more widespread deployment of AI.
[See “Benchmarking AI Uptake by Compliance Functions” (Dec. 4, 2025); and “Benchmarking Fund Managers’ Adoption and Governance of Generative AI” (Nov. 6, 2025).]
ESG
HFLR: The Trump administration has seemed very hostile to ESG, as are certain states such as Texas. We’ve already seen some pullback from ESG in the private funds space. What is the future of ESG as a concept or strategy in the private funds space in the U.S., given this current hostility?
Choe: There will continue to be certain pockets of interest in ESG or sustainability strategies, particularly among institutional investors. That’s going to be even more pronounced in the European market. We are seeing – and, going forward, there may be more – rebranding of the ESG strategy.
HFLR: ESG feels like one area where there’s a big divergence between European and U.S. regulations. Europe has really committed to ESG funds, whereas the U.S. is pulling back in some ways. Where does that leave fund managers that want to have both U.S. and foreign investors in their funds?
Aderton: That’s a very challenging situation because the regulations and investor expectations may differ so much across jurisdictions. We had a little bit of that in the U.S. in the last administration where we did see state-by-state differences. For some managers, if the strategy really is a sustainability strategy, they may feel like they need to pick a lane. For other managers, I’m hopeful that a market develops in which you can pursue strategies that meet investor demand, depending on what that demand is, such that you could potentially run a sustainability strategy for investors that are interested in that strategy and other strategies for investors who are not interested in sustainability. I recognize that the current administration’s posture toward ESG may make that a little bit more challenging, but, as a long-term solution, that really does facilitate the idea of investors’ being able to choose the strategies that best meet their investing goals.
[See “FTC and DOJ Support State Antitrust Suit Aimed at Asset Managers’ Coal Industry ESG Initiatives” (Jul. 31, 2025); “SIFMA Secures Injunction Against Missouri’s ESG Disclosure Rules” (Mar. 27, 2025); and “Tennessee Sues BlackRock Over Allegedly ‘False and Deceptive’ ESG Claims” (Feb. 1, 2024).]
CCO Priorities for 2026
HFLR: What should hedge fund manager CCOs focus on in 2026? What are some of the biggest challenges they’re going to face this year?
Choe: I started off the conversation by talking about the SEC’s exam priorities, and I think that’s always a good place to start for a CCO planning the upcoming year. We have been counseling our clients to focus on continued Marketing Rule compliance. If they are launching new products or strategies, they should focus on core areas, such as valuation, investment allocation and expense allocation.
Finally, I want to highlight compliance with Regulation S‑P (Reg S‑P). That’s one of the rules that did get implemented. The SEC has communicated that it will focus on compliance with Reg S‑P during its examinations, so CCOs should not only have adopted their policies and procedures but also be implementing a testing program to ensure they can comply with the requirements. Some of the more challenging aspects are the 30‑day breach notification requirement and the obligation to oversee service providers.
[See “SEC Staff Discuss Regulation S‑P Amendments and Related Examination Processes” (Oct. 23, 2025).]
Aderton: Analysis of [material nonpublic information (MNPI)] policies and procedures is another perennial topic that may become more significant as hedge fund managers diversify their strategies and there’s more convergence between traditional PE or private credit strategies and hedge fund strategies. As managers receive more private information – whether through a PE or private credit line of business – they need to think about how that might affect their existing MNPI policies and procedures, and how those might be enhanced to address any new business lines.
