Wall Street’s New Frontier: Kalshi’s Perpetual Futures Bid for US Stocks Sparks Regulatory Battle

The US prediction market platform Kalshi is poised to introduce a groundbreaking trading model from the fast-evolving cryptocurrency world to the heart of traditional finance. Kalshi is actively seeking regulatory approval to launch approximately 60 perpetual futures contracts tied to prominent US stocks and ETFs, including market giants like Tesla, Nvidia, and Apple. If greenlit, this initiative could allow American investors to gain price exposure to these companies even when traditional stock markets are closed.

However, this ambitious plan has quickly ignited a fierce debate among regulators and market participants. Citadel Securities, a major player in financial markets, has issued a stark warning: allowing a proliferation of US stock-linked derivatives to trade outside the SEC’s established securities framework could pave the way for a “parallel shadow market” that operates beyond conventional oversight.

Kalshi’s Bold Move: Bringing Perpetual Futures to Blue-Chip Stocks and ETFs

As reported by The Wall Street Journal on September 11th, Kalshi’s proposal involves a suite of roughly 60 perpetual futures contracts linked to high-market-capitalization stocks and exchange-traded funds. This list includes some of the most actively traded and influential companies in the US tech sector, such as Tesla, Apple, and Nvidia.

Unlike conventional futures contracts, perpetual futures have no set expiration date. This unique feature allows traders to maintain positions indefinitely, provided they meet margin requirements. To keep the contract price closely aligned with its underlying spot asset, these contracts employ a periodic “funding rate” mechanism, a hallmark innovation from the crypto derivatives space.

Kalshi’s existing perpetual products already offer leveraged trading, with official documentation citing examples of up to 6x leverage. While this amplifies potential gains, it also significantly increases risk; at 6x leverage, a mere 17% adverse price movement in the underlying asset could effectively wipe out an investor’s initial margin.

This isn’t Kalshi’s first foray into innovative derivatives. Earlier this year, in May, the Commodity Futures Trading Commission (CFTC) approved Kalshi’s Bitcoin perpetual futures (BTCPERP). The platform subsequently expanded its crypto offerings to include Ethereum, Solana, and XRP. More recently, Kalshi secured product certification for gold (GOLDPERP) and silver (SILVERPERP) perpetual contracts, with CFTC documents confirming their certification on September 8th, demonstrating the platform’s growing capabilities beyond its initial prediction market roots.

24/7 Trading: Derivatives, Not Spot Market Hours

It’s crucial to clarify that the potential launch of Tesla and Nvidia perpetual contracts on Kalshi does not signify a shift to 24-hour trading for Nasdaq or the broader US spot stock market. Instead, investors would be trading derivative contracts that mirror the price movements of these stocks, rather than the underlying shares themselves.

The Kalshi platform itself already operates almost continuously, with trading available around the clock, save for a brief routine maintenance window on Thursdays from 3 AM to 5 AM ET. This always-on trading environment is consistent with a broader trend in the US derivatives market; the CFTC, in May, issued regulatory guidance specifically addressing “24/7 trading, clearing and settlement,” underscoring the accelerating move towards round-the-clock market activity.

This momentum aligns with discussions at the Securities and Exchange Commission (SEC). The SEC recently hosted a roundtable on “24-hour trading,” bringing together key market participants like Citadel Securities, Nasdaq, Interactive Brokers, and Jane Street to deliberate on critical issues such as market liquidity, overnight trading, cybersecurity, and clearing infrastructure.

Regulatory Showdown: Citadel Warns of a “Parallel Shadow Market”

The central point of contention in this evolving landscape is the question of regulatory jurisdiction: should these novel products fall under the purview of the CFTC or the SEC?

In a strongly worded comment letter submitted to regulators on September 9th, Citadel Securities articulated its concerns. The firm highlighted that derivative products linked to publicly traded company stocks, corporate earnings, profits, or other vital metrics could inherently carry risks typically associated with securities markets, including insider trading and manipulation of spot stock prices.

Citadel’s warning is unequivocal: if these products are allowed to operate outside the SEC’s established monitoring and enforcement mechanisms, they could foster “a parallel shadow market linked to US stocks.” This shadow market, Citadel argues, would lack the fundamental protections and oversight present in traditional equity markets, such as best execution, robust order handling, trading halts, comprehensive information disclosure, and vital cross-market surveillance systems.

A key aspect of this dispute lies in the differing product approval processes of the CFTC and the SEC. CFTC-registered exchanges can sometimes introduce new products via a “self-certification” mechanism, potentially allowing trading to commence as early as the next business day. In stark contrast, new securities products under the SEC’s framework typically necessitate a period of public comment and formal regulatory approval, a much more protracted process.

Consequently, Citadel advocates against allowing trading platforms to unilaterally choose their regulator simply by reclassifying a product’s legal definition, asserting that the substance of the underlying asset should dictate the appropriate regulatory body.

Why Now? Kalshi’s Explosive Growth Meets Volatile US Markets

Kalshi’s strategic pivot towards US stock derivatives is not an isolated event but a calculated move within a dynamic market environment. Recent data from Reuters reveals Kalshi’s prediction market trading volume soared to approximately $40 billion in August alone, significantly outpacing competitors like Polymarket. Combined, Kalshi and Polymarket recorded a total trading volume of about $48.4 billion. Furthermore, Kalshi’s commodity markets, launched just seven months prior, have already surpassed $400 million in monthly trading volume, indicating robust demand for its innovative offerings.

Concurrently, the traditional US stock market itself is navigating a period of high valuations and considerable volatility. Nvidia, for instance, recently achieved a market capitalization of approximately $5 trillion, solidifying its status as one of the world’s most influential companies. While the S&P 500 and Nasdaq indices closed strongly on September 10th, reaching 7,591.70 and 26,081.72 points respectively, major indices have recently faced downward pressure. This is attributed to factors such as US bond yields nearing 5%, a surge in energy prices, and renewed market expectations of Federal Reserve interest rate hikes.

This confluence of factors suggests a compelling market opportunity. The ability to trade price exposure to popular stocks like Tesla and Nvidia continuously—even on weekends or after traditional market hours—could attract significant capital flows, potentially shifting liquidity from conventional pre-market and after-hours trading into these always-on derivatives markets.

The Blurring Lines: How Perpetual Contracts Are Reshaping Finance

Kalshi’s new initiative is more than just the introduction of 60 additional derivatives; it represents a pivotal moment where trading mechanisms perfected in the cryptocurrency market are being actively integrated into traditional finance. The features that once defined crypto trading platforms—24-hour availability, no expiration dates, funding rates, and high leverage—are now being transplanted to highly liquid traditional assets such as gold, major indices, and iconic US stocks like Tesla and Nvidia.

For investors, this paradigm shift could mean that price discovery is no longer confined to the traditional 9:30 AM New York market open. For regulators, however, the implications are far more complex: when an Nvidia perpetual contract can experience wild fluctuations on a Sunday morning, does it remain merely a “future,” or has it effectively become another iteration of the US stock market itself? This fundamental question lies at the very core of what Citadel aptly terms the “shadow market” controversy.
