Cascade, a New York-based startup, has introduced a 24/7 brokerage service for cryptocurrency perpetual contracts. The platform, which operates on a unified margin account, also covers major US stocks and assets linked to private companies like OpenAI, SpaceX, and Stripe. Currently available to a select group of invited depositors, the service is set to open to the public in early 2026. Cascade has raised $15 million from investors including Polychain Capital, Variant, Coinbase Ventures, and Archetype, and plans to expand its initial offering of over 10 perpetual markets.
