A New Era for Equity Derivatives? The Rise of Perpetual Futures

The landscape of U.S. financial derivatives could be reshaped by a novel product currently under regulatory review. KalshiEX LLC, a CFTC-designated contract market, has submitted a formal rule change proposal to the Securities and Exchange Commission, signaling its intent to introduce a groundbreaking instrument to the market.

Core Mechanics: No Expiry, Anchored by Daily Funding

Filed under SR-KALSHIEX-2026-02, the proposal outlines plans to add a new chapter to Kalshi's rulebook for listing and trading "Perpetual Security Futures Products." Unlike traditional futures contracts that have fixed settlement dates, these instruments would have no predetermined expiration, allowing positions to be held indefinitely.

The key innovation maintaining price parity with the underlying stock is a daily "Funding Rate" mechanism. This system continuously measures the difference between the futures price and the spot price of the actual stock. Based on this differential, payments are exchanged between long and short position holders. This perpetual cash flow is designed to tether the futures price closely to the spot price, preventing significant long-term divergence.

All positions would be centrally cleared and risk-managed by Kalshi's affiliated clearinghouse, Kalshi Klear LLC.

Stringent Listing Criteria: Targeting Market Titans

Access to this new product would be limited to shares of the largest and most liquid companies. Kalshi's proposal establishes high barriers for the underlying securities to ensure sufficient market depth and stability. The primary listing requirements include:

  • Market Cap: The issuing company must have a total market valuation of at least $100 billion.
  • Liquidity: The stock must have a six-month average daily trading volume exceeding $450 million.
  • Float: There must be more than 20 million shares available for public trading.

In practice, this limits potential underlying assets to mega-cap stocks like those in the "Magnificent Seven" or other blue-chip giants.

Higher Margins and Proposed Timeline

From a risk management perspective, Kalshi is opting for a conservative approach. The proposal sets the initial customer margin requirement at 15.5% of the position's value, which is 0.5 percentage points above the federal regulatory minimum of 15%.

The rule change is currently pending regulatory approval. If cleared by the SEC and the CFTC, the new framework is slated to go into effect on November 2, 2026. The final decision from regulators will be the critical determinant in whether this innovative product moves from proposal to reality.
