Perpetual Futures on Securities and 24-Hour Markets: What Cayman Fund Boards Should Settle Before the First Contract Trades

On 14 October 2026 an SEC market structure official said he expects at least four venues to begin trading perpetual futures on securities this quarter, and that US markets will "soon be 23-by-5", with 24-by-7 trading to follow. These are remarks by a staff official, not Commission rules, and the contract terms have not been published. The operational questions they raise are nonetheless concrete: how a fund values a position that trades while its administrator is closed, how it funds a contract with no expiry, and which body approves a new instrument class. This article sets out what changed this week, what did not, and what a Cayman fund board and its investment manager should have in place before the first contract lists.

The product is not the difficult part. A perpetual future is a derivative with a funding mechanism. The difficult part is that the net asset value, the margin position and the risk report were all designed around a market that closes. When the market stops closing, the fund's controls have to be rewritten around a clock, not a calendar.

Executive Summary

The week's most significant institutional development was a signal on timing, not a rule change. A senior SEC official told a market structure conference that perpetual futures on securities are likely to start trading before year end, that continuous trading is approaching, and that the equity market structure rulebook is under review. The same week, a US trading infrastructure provider disclosed plans to enter prime brokerage in the first quarter of 2027, aimed at funds that hold tokenised and conventional equity positions together.

• Five CFTC-registered designated contract markets filed Form 1-N notices with the SEC in September 2026 to register as security futures exchanges. The official expects at least four to list perpetual futures on securities in the fourth quarter. He did not name the venues, the securities or the contract terms.
• Near-continuous trading is the stated direction: 23 hours a day, five days a week, then 24 hours a day, seven days a week. The official said Regulation NMS Rules 610 and 612 are under review, with recommendations expected by year end.
• Prime brokerage is moving toward the product. One entrant plans a Q1 2027 launch and describes settlement mismatch between pre-funded crypto venues and later-settling US equities as the central financing problem.
• For a Cayman fund, the exposure is governed by the offering document, the valuation policy and the board's oversight framework, not by the SEC's market structure agenda. The relevant work is internal and can begin now.

Background: Why a Contract Without an Expiry Changes the Operating Model

A conventional futures contract expires on a fixed date, and its price converges on the underlying asset at expiry. A perpetual future has no expiry. A periodic funding payment between long and short holders keeps the contract price close to the reference price. Perpetual futures developed in digital asset markets and are now the dominant derivative form there. The development this week is the prospect of the same construct being offered on securities.

US-listed security futures have existed for years, but they are expiry-dated and have seen limited volume. In July 2026 a major derivatives exchange launched cash-settled single-stock futures on more than 50 US stocks, which are also expiry-dated. A perpetual contract on a stock is a different instrument for a fund to hold. It has no roll, a funding cost or credit that varies with positioning, and potentially very high leverage depending on margin terms that are not yet known.

The regulatory path is also unusual. Under the registration route the five venues used, a notice registration is understood to take effect on filing, rather than after an exchange application is approved. Registration is limited to trading security futures products. It does not authorise a general cash equities exchange. The Commission's role, as the official put it, is to ensure compliance and support competition, not to judge commercial success.

What Happened This Week

The table separates what has been verified against a primary source from what rests on a single secondary report. Dates are 2026.

Why Institutions Care

Three groups have a direct interest. Long/short equity and event-driven managers gain a possible synthetic route to single-name exposure without borrowing stock or rolling expiries. Multi-strategy and digital asset managers already running perpetual books on crypto venues may be able to run a similar book on equity names, under one margin relationship. Allocators will ask how any fund using the instrument controls leverage, gaps and funding cost.

The commercial attraction is capital efficiency and access outside exchange hours. The risk is that capital efficiency and out-of-hours access arrive before the fund's infrastructure is ready for them. The sequence matters. A fund that adopts an instrument first and rewrites its controls afterwards invites an operational incident and an awkward conversation at its next due diligence meeting.

Operational Implications

The binding constraint for most managers will be the administrator and the prime broker, not the exchange. The table lists the areas where a continuous or near-continuous market changes a routine process.

None of these is novel in isolation. Crypto-native managers have lived with most of them for years. Managers with an equity heritage, and the service providers that support them, have not.

Governance Implications

Adding an instrument class is a governance decision before it is a trading decision. The investment manager proposes; the board decides whether the use is within the fund's authorised investment powers and risk appetite. As a matter of prudent practice, rather than any rule specific to these contracts, a board would expect to see five items before approving first use.

1. A written assessment that the instrument falls within the investment objective, strategy and restrictions in the offering document.
2. Leverage and margin limits expressed at fund level, with a stated response to a margin call.
3. A valuation approach agreed with the administrator, including the pricing source, the cut-off and the fallback if the source is unavailable.
4. A counterparty and venue assessment covering clearing, segregation of client assets and default procedure.
5. A conflicts review, in particular where a venue, prime broker or liquidity provider is affiliated with another party to the trade. The framework in our conflicts of interest guide applies.

Boards should also settle who can pause trading in the instrument. A perpetual market that runs continuously needs a defined escalation route that works outside office hours.

Regulatory Implications

It helps to keep the layers apart.

• Binding law and rules. Security futures are subject to US federal securities and commodities regimes. The SEC's Form 1-N process is existing procedure. The Regulation NMS review and the CFTC's Regulation CTX and CAM notice are proposals or reviews, not rules. The CFTC comment deadline of 14 December 2026 is a fixed date.
• Official signals. The 14 October remarks describe expectations. They are not commitments by the Commission and do not set contract terms.
• Market practice. Settlement mismatch, collateral conversion and netting are being worked on by private firms. None is settled practice yet.
• Our recommendation. Treat the Q4 timeline as a planning assumption and the contract specification, once published, as the first document to read.

Eligibility is an open point. Whether non-US funds can access these venues, and on what documentation, depends on the venue's terms and on each fund's own regulatory position. Managers should not assume access.

Cayman Implications

A Cayman fund is not subject to the SEC's market structure rules as such. It is exposed through the venues, brokers and counterparties it uses, and its manager's own regulatory status. The Cayman questions are therefore about the fund's constitution and oversight.

First, the offering document. A regulated mutual fund describes its investment objective, strategy and risks, and material changes to those descriptions need to be handled through the process the Mutual Funds Act and CIMA's requirements prescribe. Whether adding perpetual futures on securities is a material change depends on the existing disclosure. Counsel should confirm the mechanics for each fund; we flag this as an item for verification rather than a conclusion.

Second, valuation. CIMA's expectations on valuation oversight, and the board's duty to ensure NAV is calculated on a defined and consistent basis, are the relevant test for a 24-hour instrument. The valuation policy, not the venue, answers the question of which price the fund uses.

Third, segregated portfolio structures. Where a fund is a segregated portfolio of a segregated portfolio company, margin, collateral and funding liabilities belong to the portfolio that entered the trade. Documentation with the prime broker and venue should state this clearly. Our guidance on choosing a Cayman fund platform covers how that boundary is tested in due diligence.

Digital Asset Implications

Digital asset managers have the most relevant experience and the most to gain, and also the most to unlearn. The venues in the filings are existing CFTC-registered exchanges, several with crypto businesses. The convergence is visible in three places.

• Continuous trading is the norm in crypto. A manager with a crypto perpetual book already runs a valuation cut-off, intraday margin and funding accruals. That discipline transfers to equity perpetuals.
• Tokenised equities are a growing collateral and hedging pool. The company-reported USD 3.5 billion of underlying shares behind tokenised products is small against equity markets but is the base on which hedging between tokenised shares and futures would be built. Our recent piece on tokenised collateral and prime brokerage covers the collateral side.
• Custody and banking access shape what is possible. The US Comptroller of the Currency published findings on 14 October that nine large national banks had policies restricting services to several sectors, including digital asset activities, between 2020 and September 2025. The OCC is considering further changes to its supervisory framework. For managers, banking access for cash and margin movement is part of operational readiness.

Risks

• Leverage and gap risk. Margin terms are unknown. A fund should assume that a high-leverage contract on a single stock can move through its margin in a thin overnight market.
• Valuation disputes. A fund that values at a different time or source to its prime broker or administrator will produce breaks and, in a stress, disagreement over NAV.
• Funding cost drift. Funding payments can change sign and size with positioning. They need to be visible in attribution, not buried in realised profit and loss.
• Venue and counterparty risk. New venues have no operating history in this product. Due diligence on clearing, default waterfalls and asset segregation is the investor's protection.
• Regulatory reversal. A product expected this quarter can be delayed. A fund that builds around a single launch date is exposed to a change in timing.
• Disclosure drift. Using a new instrument without updating risk disclosure creates a difference between what investors were told and what the fund does.

Opportunities

• Managers who prepare controls first can adopt the instrument quickly if it proves useful, and can say so credibly to allocators.
• Prime brokerage competition across tokenised and conventional equities may lower financing cost and widen collateral choice over time. The USD 3.5 billion and 2027 timeline are early indicators, not outcomes.
• Funds with institutional governance have an advantage in due diligence. A written new-instrument approval process is a differentiator when allocators ask how the manager controls scope drift.

Looking Ahead

Key Takeaways

• The signal is timing: at least four venues expected to list perpetual futures on securities this quarter, with continuous trading to follow. It is an official's expectation, not a rule.
• The first controls to build are valuation cut-off, intraday margin and funding accrual.
• A board should approve a new instrument class in writing before first use, with leverage limits and a valuation approach agreed with the administrator.
• Cayman exposure arises through the fund's documents and counterparties. Check the offering document and confirm the amendment mechanics with counsel.
• Do not assume venue access for non-US funds. Read the contract specification and venue terms when published.

Conclusion

Market structure change tends to reach funds through operations before it reaches them through returns. The managers who handle this transition well will not be those who trade the first contract. They will be those whose valuation policy, margin procedures and board approvals were ready when the contract arrived. That preparation costs little now and is difficult to improvise later.

The CV5 Capital Perspective

The following is the practical view from operating Cayman hedge fund and digital asset fund structures. It is commentary, not advice, and each fund's position depends on its documents.

What fund managers should do this week

Write down your valuation point and pricing source for any instrument that trades outside exchange hours, and confirm it with your administrator. Ask your prime broker how margin calls are issued and met outside business hours. If you intend to use perpetual futures on securities, draft the new-instrument paper for your board now, so that the approval step does not become the bottleneck at launch.

What institutional investors should monitor

Watch for the contract specifications, margin schedules and eligible-participant rules once published. Ask managers who intend to use the instrument for their leverage limit, valuation approach and gap-risk testing. Treat a manager's ability to answer these precisely as an operational diligence signal.

Governance actions boards should consider

Add a standing agenda item on new instruments and venues. Require a written scope check against the offering document before first use. Confirm who is authorised to pause trading outside office hours and how the board is informed.

Operational enhancements worth evaluating

Review whether your administrator can accept continuous trade feeds and a fixed timestamp convention. Test a margin call at an awkward hour, including collateral movement across banking and token rails. Add funding payments as a separate line in attribution and accruals.

Compliance considerations

Check that risk disclosure and marketing language describe the instruments actually used. Review personal trading and conflicts policies for any affiliated venue relationships. Confirm with counsel whether adding the instrument requires an offering document update or a notification to CIMA.

Regulatory developments to watch

The SEC's Regulation NMS review, the CFTC comment period closing on 14 December, the SEC custody proposal comment deadline of 5 December, and any contract-level disclosures from the first venues to list.

Expected market developments over the coming weeks

Our expectation, and it is an expectation, is that one or more venues will announce contract specifications before year end, that prime brokers will publish their position on eligibility and margin, and that early volumes will be modest. Managers should plan for a gradual start rather than a step change.

Frequently Asked Questions

What is a perpetual future on a security?

It is a futures contract with no expiry date whose price is kept close to a reference price through periodic funding payments between long and short holders. Perpetual futures developed in digital asset markets. The contract terms for securities versions have not been published in the sources we reviewed.

Have perpetual futures on securities started trading in the US?

Not as of 19 October 2026 in the sources reviewed. An SEC official said on 14 October that he expects at least four venues to begin trading them this quarter. That is an expectation and not a Commission announcement.

Can a Cayman fund trade these contracts?

It depends on the fund's investment powers and disclosure, the manager's regulatory position, and each venue's eligibility terms, which are not yet public. A board should approve the use in writing and counsel should confirm whether any document update or CIMA notification is needed.

How should a fund value a contract that trades around the clock?

The valuation policy should fix a pricing time and source, apply them consistently and be agreed with the administrator, with a fallback if the source is unavailable. The choice is a governance decision for the board and manager, not a venue decision.
