The introduction of perpetual futures into regulated markets has sparked concerns about systemic risk, with critics warning that these high-leverage instruments could destabilize the market. However, this critique is misplaced, as the risk is not inherent to the contract, but rather a result of the venue's design, including leverage limits, margin rules, and default handling.

The recent history of crypto's sharpest deleveraging episodes, such as the October 2025 cascade, highlights the importance of understanding the risk transmission mechanism, which is often driven by liquidation cascades. The real question is not whether perpetuals belong in regulated markets, but how a given venue is built to handle defaults and contain risk.

Regulatory requirements, such as segregated funds and a registered clearing entity, are necessary to secure the baseline, but it is the venue's design that ultimately determines its ability to manage risk. The debate over perpetuals is often framed as a question of risk, but it is also about the role of these contracts in institutional trading. While some argue that perpetuals are not a suitable replacement for regulated futures, others see them as a valuable tool for hedging delta exposure.

The key to unlocking the potential of perpetuals lies in their liquidity, which is drawn in part by retail flow. By providing a deep and durable pool of liquidity, perpetuals can become a vital component of institutional trading strategies. The question is not whether perpetuals are dangerous, but how a venue handles defaults when the market is under stress.

Regulated clearing has established a standard for managing defaults, and it is this standard that Bullish is building towards. By adopting a clearing model that starts with the defaulter and works its way through the order book or auction, venues can break the chain of risk transmission and contain failures. This approach is not a complete elimination of risk, but it is a crucial step towards creating a safer and more stable market. Ultimately, the design of the venue is what determines its ability to manage risk and provide a safe and stable environment for institutional trading.
