Deep Tide TechFlow news: On September 23, according to the U.S. Federal Register, KalshiEX LLC (Kalshi) submitted a rules change application to the SEC on September 18, 2026 (document number SR-KALSHIEX-2026-02). It plans to add Chapter 14 to its rules manual to allow exchange-listed trading of "perpetual security futures products" (Perpetual SFPs) with no predetermined expiration date. The underlying asset is a single stock.

This product uses a daily funding rate mechanism to drive futures prices to converge with the underlying stock’s spot price. Long and short parties pay each other funding fees based on the difference between the daily settlement prices. All positions are cleared by Kalshi’s clearing entity, Kalshi Klear LLC.

Regarding listing requirements, the underlying securities must meet stringent conditions such as having a market value of no less than USD 100 billion, average daily trading volume (ADTV) over the past six months of no less than USD 450 million, and deliverable shares in public float exceeding 20 million, among others. The client margin requirement is set at 15.5% of the position market value, which is higher than the statutory minimum standard (15%). The proposed rule change is intended to take effect on November 2, 2026, and as of now, the CFTC has not completed approval.
