AMMs vs. Traditional Market Making in Crypto: A Complete Comparison

How Automated Market Makers Work

Automated market makers replace the order book with a liquidity pool and a pricing algorithm. In the most common design, the constant product market maker (x * y = k), two assets are deposited into a pool in a specific ratio. The price of each asset is determined by the ratio of reserves in the pool, and it changes automatically as trades shift the balance.

When a trader wants to buy Token A using Token B, they deposit Token B into the pool and withdraw Token A. The pricing formula ensures that the product of the two reserves remains constant, which means larger trades have progressively worse pricing (slippage). This mechanism provides continuous liquidity without any active management by the liquidity providers.

More sophisticated AMM designs have emerged to address the capital efficiency limitations of constant product models. Concentrated liquidity (pioneered by Uniswap V3) allows LPs to specify price ranges for their capital, dramatically improving capital efficiency within those ranges. Curve's StableSwap algorithm optimizes for assets that trade near parity, offering much tighter spreads for stablecoin pairs. Balancer introduced weighted pools that support arbitrary asset ratios.

Liquidity providers in AMMs earn a share of trading fees proportional to their share of the pool. However, they face impermanent loss, which occurs when the price ratio of the pooled assets changes relative to when the LP deposited. In volatile markets, impermanent loss can exceed fee income, resulting in a net loss for the LP compared to simply holding the assets.

• Constant product formula (x * y = k) provides continuous pricing without an order book
• Concentrated liquidity and specialized curves improve capital efficiency
• Liquidity providers earn fees but face impermanent loss risk
• No active management required, but passive exposure to directional risk

Where Traditional Market Making Excels

Traditional order book market making offers several structural advantages over AMMs, particularly for institutional participants and in markets that demand tight spreads and deep liquidity.

Capital efficiency is significantly higher in traditional market making. A skilled market maker can provide substantial liquidity with relatively modest capital because they actively manage inventory and hedge positions. In an AMM, capital is spread across the entire price curve (or a specified range), and much of it may sit idle at prices far from the current market. Research has shown that active market makers can provide equivalent liquidity depth with 5x to 10x less capital than a comparable AMM pool.

Pricing flexibility is another advantage. Traditional market makers can incorporate information from multiple sources, including order flow analysis, cross-venue pricing, volatility forecasts, and fundamental data, into their quoting decisions. AMMs use a fixed formula that cannot adapt to information. This means traditional market makers can adjust spreads in response to changing conditions, reducing adverse selection risk.

Risk management in traditional market making is active and dynamic. Market makers can hedge on correlated instruments, adjust position sizes, widen spreads during volatile periods, and withdraw from the market entirely if conditions become unfavorable. AMM liquidity providers have limited ability to manage risk without withdrawing from the pool entirely.

For institutional-scale operations, traditional market making provides the auditability, compliance controls, and performance attribution that regulated entities require. Every quote, fill, and hedge can be logged, analyzed, and reported in a way that is difficult to achieve with AMM-based strategies.

• 5x to 10x greater capital efficiency compared to AMM liquidity provision
• Dynamic pricing that incorporates information, volatility, and order flow signals
• Active risk management with hedging, position limits, and the ability to withdraw
• Full auditability and compliance compatibility for regulated institutions

The Convergence: How Both Approaches Are Evolving

Rather than one model replacing the other, the market is converging toward hybrid approaches. AMMs are becoming more sophisticated, incorporating features that resemble traditional market making. Traditional market makers are increasingly providing liquidity on decentralized venues alongside centralized exchanges.

On-chain AMMs are adding oracle-based pricing, dynamic fees that adjust with volatility, and concentrated liquidity ranges that more closely resemble active order management. Some protocols now allow external market makers to manage liquidity positions programmatically, effectively turning the AMM into an infrastructure layer for professional market making.

Traditional market makers are deploying capital into DeFi, running sophisticated strategies that rebalance concentrated liquidity positions, manage impermanent loss through hedging, and optimize across both centralized and decentralized venues simultaneously. Platforms like Mercury Pro enable this by providing unified connectivity to both centralized exchanges and DeFi protocols.

For institutional market makers, the question is not AMM versus order book. It is how to deploy capital efficiently across both venue types while maintaining comprehensive risk management. The firms that succeed will be those with technology that spans both paradigms and risk frameworks that account for the unique characteristics of each.

• AMMs are adding dynamic fees, oracle pricing, and concentrated liquidity ranges
• Traditional market makers are deploying capital into DeFi with hedged strategies
• Hybrid approaches span both centralized and decentralized venues
• Unified technology platforms enable cross-paradigm market making strategies

Choosing the Right Approach for Your Operation

The optimal approach depends on the institution's scale, regulatory requirements, technology capabilities, and target markets.

For firms focused on major trading pairs (BTC, ETH, SOL) on centralized exchanges, traditional order book market making will deliver superior capital efficiency and risk management. The technology requirements are significant, but platforms like Mercury Pro provide the core infrastructure.

For firms looking to capture DeFi-native yield opportunities, AMM-based strategies on concentrated liquidity protocols can be attractive, particularly when paired with hedging on centralized venues. This requires expertise in both DeFi protocol mechanics and traditional risk management.

For the largest institutional market makers, a combined approach that spans centralized exchanges, OTC desks, and DeFi protocols provides the broadest opportunity set. This requires unified technology that can manage positions and risk across all venue types, which is precisely the infrastructure challenge that Mercury Pro was built to address.
