On August 29, 2026, Hyperliquid truly "empowered" the HIP-4 prediction market layer: the previously restricted deployment permissions were rewritten into a permissionless framework for third parties, allowing any external team to directly build their own prediction markets on this layer. In the 28 days following the reopening, according to the Hyperliquid Research Collective, the average daily trading volume of HIP-4 surged from about $545,000 to approximately $2.75 million, nearly tripling, while the number of active traders climbed to around 1,841, with the Outcome market operated by leading teams capturing about 85% of the trades, quickly turning this newly opened traffic channel into a major battleground for concentrated betting. On the surface, this is a textbook scenario of decentralized prediction markets realizing growth dividends at the product and structural levels: a unified account system supports users in flexibly hedging between prediction markets and perpetual contracts, while permissionless deployment allows more strategy teams to enter the fray. However, at the same time, U.S. regulations were tightening on the other end—SEC Chair Paul Atkins made it clear that he hoped the CLARITY bill aimed at setting regulatory boundaries for digital assets could pass the Senate and be submitted for the President’s signature before September 15, but as of September 3, 2026, the bill remained in the legislative process, with U.S. prediction markets wandering in the overlapping and ambiguous areas of SEC, CFTC, and gaming regulations, while public information did not show that regulators had taken direct action against Hyperliquid or the Outcome market, leaving HIP-4’s cross-border expansion on the edge of an unmarked regulatory red line.
Permissionless Opening: Surge in HIP-4 Trading Volume
For HIP-4, the real turning point came on August 29, 2026. Previously, the deployment permissions for this prediction market layer were held by a few teams, filtering who could create tradable events and who qualified to launch new contracts through an invisible threshold. On this day, Hyperliquid removed that threshold—according to a report from the Hyperliquid Research Collective, HIP-4 then allowed third-party teams to deploy prediction markets directly without permission, enabling any external team to construct their own event markets on this layer. This was followed by an almost vertical rise in trading volume: in the 28 days prior to the opening, the average daily trading volume of HIP-4 was around $545,000, and in the 28 days post-opening, it soared to about $2.75 million, nearly tripling; the number of active traders during the same period reached approximately 1,841, with the Outcome market swallowing up about 85% of the trading volume, further amplifying the dominant role of the leading market in overall liquidity. The report directly concluded that permissionless deployment significantly boosted trading volume, but under unchanged compliance and customer acquisition environments, market entry remained the primary limiting factor to platform growth.
What regulatory observers and professional traders should pay close attention to is the structural design behind this surge in volume. Hyperliquid’s unified account system integrates prediction markets and perpetual contracts within the same margin and risk framework, allowing traders to bet on a particular event while simultaneously hedging directional or volatility risks with perpetual contracts, finely adjusting their exposure within the same account. For professional funds still willing to enter a compliance environment that remains unclear and regulatory paths that are not defined, this one-stop hedging and capital management capability reduces the cost of executing strategies and subjectively weakens the resistance to "platform migration," making it easier for them to place their chips on HIP-4 when weighing regulatory uncertainties against strategy efficiency.
Outcome Monopolizes 85%: Risks of Concentrated Liquidity
In the first month after the permissionless opening, the story of HIP-4 quickly transformed into a "single-act" performance—according to a single source, the Outcome market captured approximately 85% of the trading volume, achieving almost total dominance over liquidity in a daily average of about $2.75 million. For other prediction market teams that had just gained deployment freedom, such a head monopoly meant that users' attention, market-making funds, and professional traders’ risk exposures were almost all locked into the same pool, leaving other categories to scramble for very limited natural inflows at the fringes.
The direct consequence of highly concentrated liquidity is that it turns "technical permissionlessness" into "economic high barriers." Any team can launch new markets on HIP-4, but if they cannot gather sufficient funds and depth in a short time, they can only face high slippage and low trading environments in stark contrast to Outcome, quickly raising customer acquisition costs and retention difficulties. The Hyperliquid Research Collective also pointed out this paradox in their report: permissionless deployment significantly increased overall trading volume, yet the true limitation to platform expansion remained market entry itself, with funds, user attention, and compliance resources continuing to concentrate toward a few leading markets. Under the current circumstances in the U.S. where regulations are still ambiguous, and prediction-type products face potential scrutiny pressures from the SEC, CFTC, and gaming frameworks, new teams attempting to operate compliantly for U.S. investors must bear legal and licensing costs far exceeding simple technical access, further solidifying Outcome’s advantageous position and transforming HIP-4’s entry barriers from “can it go on-chain” to “can it cross the dual walls shaped by liquidity monopolies and regulatory uncertainties.”
SEC Chair Bets on CLARITY
Outside the dual walls of regulatory ambiguity and licensing costs, U.S. regulators are also attempting to redraw the boundaries of the playing field. SEC Chair Paul Atkins has publicly stated that he hopes the CLARITY bill intended for digital assets can pass the Senate and be submitted to the President for signature by September 15. According to a single source, this is nearly a legislative bet made directly by the regulators: if the timing is realized, the SEC will have an additional written framework for dealing with tokenized products rather than continuing to rely on case-by-case enforcement and analogous precedents to “satisfactorily” address the rapid evolution of prediction markets.
CLARITY is seen as an attempt to provide clearer regulatory boundaries for digital assets (including tokens related to prediction markets), directly targeting the current identity fragmentation of prediction-type products in the overlapping jurisdictions of the SEC and CFTC, as well as multiple scrutiny frameworks in sports and gaming. For frameworks like HIP-4, the ultimate direction of the bill will determine its compliance narrative in the U.S.: if legislation clarifies that certain prediction tokens are closer to investment contracts, then SEC disclosure and registration pathways will become central; if it leans towards treating them under the perspective of event contracts to be handled by the CFTC or gaming regulatory systems, then the platform will need to rewrite its script regarding licensing types, product structures, and even how it opens up to U.S. users. As of September 3, 2026, CLARITY is still progressing without being effective, and the regulatory boundaries for prediction markets and related tokens in the U.S. remain uncertain, making this bill, which Paul Atkins is betting on, one of the core variables determining whether cross-border prediction markets like HIP-4 can find a clear regulatory identity and a long-term compliance route in the U.S.
Access Ceiling: Growth Boundaries of Prediction Markets
The Hyperliquid Research Collective stated bluntly in their report: the surge in HIP-4’s trading volume comes from permissionless deployment, but what truly hinders growth is “market entry” rather than computing power or product design. On the technical level, third-party teams can now easily launch their prediction markets on HIP-4, and the unified account system bridges this with perpetual contracts, presenting almost no additional engineering barriers for professional traders. However, on the legal level, who can legally open these markets to which people, and under what identity, is an entirely different logic. Permissionlessness merely removed technical review but did not secure a reliable compliance identity for any team in the U.S. or other major jurisdictions.
Reality constraints begin to surface in the U.S. Domestic prediction market platforms in the U.S. typically face the overlapping scrutiny of securities, commodities, and gaming regulations, needing to consider both SEC and CFTC perspectives while also predicting whether certain event types, like sports, will trigger gaming scrutiny. This determines whether they dare to publicly reach out to retail and institutional investors in the U.S. Even in other countries or regions, providing such products to local users often still involves compliance configurations like license applications, KYC processes, and geographical restrictions. For external teams working on HIP-4, permissionless deployment means they no longer need to explain their technical solutions to Hyperliquid, but it does not imply they can bypass local identity verification and geographical restrictions, treating every potential user as a “naturally accessible” global traffic pool.
This is also the subtlety of the current risks: as of September 3, 2026, there have been no specific regulatory actions or penalties from the CFTC or SEC against Hyperliquid or the Outcome market found in public records; the pressure does not stem from established cases but from an undeveloped rule framework. The CLARITY bill is still in the legislative advancement stage, and how the U.S. will ultimately define on-chain prediction markets and relevant tokens, and how the line between SEC and CFTC will be drawn, remains undecided. In such a regulatory gap, the permissionless opening of HIP-4 has, in fact, expanded global access, lowering the participation thresholds for cross-border teams and non-U.S. users to extremely low levels but simultaneously amplifying the compliance uncertainty for both U.S. users and the platform, making this growth curve destined to continually test a new balance between technological breakthroughs and regulatory ceilings.
From Experimental Platform to Compliant Asset: Next Steps in the Game
In the 28 days following the permissionless opening, the average daily trading volume of HIP-4 increased from about $545,000 to approximately $2.75 million, with active traders increasing to around 1,841, and the Outcome market capturing approximately 85% of the trades. The Hyperliquid Research Collective views this surge as empirical evidence that “once access is opened, demand immediately floods in”—demonstrating that prediction markets still exhibit an almost greedy growth curve, despite the compliance shadow not having dispersed. What remains truly undecided is what legal coordinate system this curve will ultimately be incorporated into: if the CLARITY bill is passed in the U.S. legislative process, it is expected to provide clearer regulatory classifications for digital assets and prediction market tokens, guiding layers like HIP-4 from “cross-border gray experiments” to “predictable compliant assets”; conversely, beyond SEC Chair Paul Atkins’ anticipated timetable, the uncertainty of the bill's direction, the strength and direction of future statements from the SEC and CFTC, and whether Hyperliquid proactively reinforces geographical restrictions and compliance whitelist measures will jointly determine the sustainable boundaries of this prediction market track, directly reshaping the extent to which platforms and users are willing to incur behavioral costs between risk and freedom.
