Longbow

Longbow Perps brings perpetual futures to Robinhood’s testnet, introducing an onchain market for both humans and AI agents. The global futures market already trades over $1 trillion in notional volume every day, yet traditional futures remain inefficient due to expiration dates that force position rollovers and liquidity fragmentation across contracts. Perpetuals solve this by enabling continuous markets with no expiry and unified liquidity. Demand is already proven: Hyperliquid processed $2.7 trillion in trading volume in 2025, nearly 2x Coinbase’s annual volume. With 27 million funded accounts, Robinhood brings unmatched distribution as it moves equities onchain, positioning itself to capture one of the largest markets in finance. Longbow Perps is built for humans and natively designed for AI agents.

On Friday at NYC Founder House I came up with the idea and drafted the initial spec. Saturday I got to work, deploying the contracts on the Robinhood testnet, wiring up the frontend, and building a simple onboarding flow. Late Saturday night into Sunday I focused on recording the pitch video and demo. Excited to ship this and see where it goes.

No funding raised.
