Market makers are the invisible engine behind every crypto trade, determining whether a trader pays a razor-thin spread or loses several percentage points to slippage — and as the collapse of Alameda Research demonstrated in late 2022, the sudden disappearance of a single large liquidity provider can crater market depth across the entire industry for more than a year.
What a Market Maker Actually Does
A market maker is a firm or algorithm that continuously places both buy and sell orders on an exchange, earning the difference between the two prices as compensation for standing ready to trade. The U.S. Securities and Exchange Commission defines a market maker as any dealer that holds itself out as willing to buy and sell a given security for its own account on a regular or continuous basis.
Citadel Securities, the world's largest traditional market maker, describes the practice more plainly as providing a two-sided quote, meaning the firm stands ready to both buy and sell at competitive prices regardless of market conditions.
In crypto, the principle is the same but the context is far more chaotic.
A market maker on Binance might set a bid at $999.60 and an ask at $1,000.40 for Bitcoin (BTC), capturing a small spread each time both orders fill. CoinGecko illustrates this with Bitcoin specifically, noting that a market maker setting orders to buy at $73,450 and sell at $73,550 captures a $100 spread per round-trip.
Multiply that by thousands of transactions across hundreds of pairs, running nonstop every day of the year, and the business model becomes clear.
What separates crypto from traditional stock market making is scale and fragmentation.
Traditional market makers operate during fixed trading hours, under formal regulatory obligations, on a handful of centralized venues. Crypto market makers operate around the clock across more than 370 exchanges globally, each with independent order books and no regulatory designation requirements in most jurisdictions. DWF Labs describes how modern market makers dynamically adjust their spreads, widening them during turbulent conditions and tightening them in calm periods to capture more flow.
This is not passive order placement — it is continuous, millisecond-level risk recalibration.

How Two-Sided Quoting Compresses the Spread
The most direct benefit market makers provide to ordinary traders is narrower bid-ask spreads. Optiver, one of the world's largest traditional market making firms, explains that competition among market makers generally leads to tighter spreads because each firm tries to outbid competitors for order flow.
The data in crypto confirms this dramatically. Kaiko Research reports that the BTC/USDT pair on Binance carries an average spread of roughly 0.0014 basis points, which amounts to essentially zero cost. BTC/USD on Coinbase runs around 0.086 basis points. These figures rival or beat spreads found in U.S. equities.
Move to altcoins, however, and the picture shifts sharply.
Kaiko found that pairs like DASH/USD, EOS/USD, and ATOM/USD on Coinbase exhibit significantly wider and more volatile spreads. Some fluctuate dramatically even minute to minute.
Meanwhile Dogecoin (DOGE) and RNDR came in tighter than expected, driven by differences in exchange fee structures and the presence of dedicated market makers on those specific pairs.
Clara Medalie, a former Kaiko analyst, wrote that the bid-ask spread serves as one of the most reliable indicators of market liquidity, and that tracking it across exchanges reveals stark differences in execution quality for the exact same asset. The spread a trader pays is not just a function of the asset itself but of which exchange they use and how many market makers compete there.

Why Order Book Depth Matters More Than Price
Beyond the spread, order book depth — the total volume of bids and asks near the current mid-price — determines how much a large order will move the market.
Amberdata, an institutional data provider, frames this in practical terms: for an institutional trader, high depth means that placing a moderately large order is less likely to cause a significant price swing, while shallow depth means that same order could move the market substantially.
Kaiko's concentration report quantifies just how unevenly depth is distributed.
More than 91% of global market depth and nearly 90% of volume sits on just eight exchanges, with Binance alone accounting for roughly 30% of depth and more than 60% of volume. The long tail of smaller exchanges offers thin books and costly execution.
This matters because slippage — the gap between the expected price and the actual fill price — rises in direct proportion to how thin the order book is. A trader executing a $100,000 sell order on a deep BTC/USDT book may lose fractions of a penny per coin.
The same order on a low-liquidity altcoin pair could cost several percentage points. Kraken's blog captures this dynamic by noting that in an illiquid market, orders have a significant price impact, which discourages legitimate trading activity entirely.

Price Discovery Across Fragmented Exchanges
Market makers also serve a less visible but equally important function: they synchronize prices across fragmented venues. With the same asset trading on dozens of exchanges simultaneously, market makers and arbitrageurs buy where prices are low and sell where they are high, forcing convergence.
CoinAPI notes that price discrepancies of $50 to $200 per Bitcoin between exchanges are common throughout the day. But what used to be gaps of 1 to 2% have narrowed to 0.05 to 0.2% thanks to competition among market-making firms running cross-venue strategies.
This cross-exchange alignment — spatial arbitrage, triangular arbitrage, and DEX-to-CEX arbitrage — collectively pushes crypto toward fairer pricing for everyone.
Without this mechanism, two traders on different exchanges could pay meaningfully different prices for Ethereum (ETH) at the same moment. Market makers compress those differences to near-zero on the most liquid pairs.

The Alameda Gap: What Happens When Liquidity Vanishes
The most vivid demonstration of why market makers matter came in Nov. 2022, when FTX collapsed and took Alameda Research — one of crypto's largest market makers — down with it. Kaiko coined the term "Alameda Gap" to describe the liquidity crater that followed.
The combined 2% market depth for Bitcoin, Ethereum, and the top 30 altcoins plummeted to roughly $800 million, about 55% lower than pre-FTX levels.
Before the collapse, it took approximately $1.8 billion in resting orders to move prices 2% in either direction. Afterward, far less capital was needed to cause the same swing.
The gap persisted stubbornly.
A full year later, 1% market depth remained about half of what it had been before FTX. Bitcoin's depth did not recover to prior levels until 2024, and Ether plus top 50 altcoins continued lagging their earlier liquidity highs. The episode proved that the loss of even one major liquidity provider ripples through the entire market for months.
For retail traders, thin liquidity translates directly to money lost.
Kaiko's analysis found that selling $100,000 worth of Worldcoin (WLD) on Uniswap V3 would incur roughly 6.3% slippage, meaning the trader receives only about $93,600 in USDC (USDC).
During the Solana (SOL) network outage in Feb. 2023, market makers pulled SOL liquidity and bid-ask spreads ballooned, costing traders significant slippage on even moderate-sized orders.

How Exchange Fee Models Incentivize Market Making
Major exchanges understand that liquidity attracts traders, so they structure fees to reward market making. The universal approach is the maker-taker model, where limit orders that add liquidity to the order book pay lower fees or receive rebates, while market orders that consume liquidity pay higher fees.
Kraken explains that maker fees start at 0.25% and taker fees at 0.40%, but both decline with volume. At $5 million or more in 30-day volume, maker fees drop to zero. Kraken also offers explicit maker rebates on more than 425 lower-liquidity trading pairs to attract dedicated liquidity providers to thin markets.
Binance starts at 0.10% for both makers and takers, but VIP tiers reduce maker fees substantially.
On futures, top-tier makers pay nothing. Coinbase Advanced begins at 0.60% maker and 1.20% taker for small volumes but reaches zero maker fees at $100 million or more in monthly volume.
Orcabay, a crypto market making firm, describes these programs as tailor-made initiatives aimed at rewarding participants who add substantial depth to the exchange's order book. The logic is self-reinforcing: deeper order books produce tighter spreads, tighter spreads attract more traders, more traders generate more fee revenue, and exchanges share that revenue back with liquidity providers.

Four Species of Market Maker
Crypto market making is not monolithic. Four distinct types operate with different mechanics and risk profiles.
Designated market makers are firms with formal arrangements to provide continuous liquidity on specific pairs. Wintermute, the largest crypto-native market maker, processes more than $5 billion in daily trading volume across 50-plus exchanges and maintains deep order books for 350-plus trading pairs.
GSR Markets, founded by former Goldman Sachs executives, connects to more than 60 venues. Jump Crypto brings decades of high-frequency trading infrastructure from traditional markets.
Algorithmic and quantitative market makers — often the same firms — use strategies including continuous quoting, order-book imbalance monitoring, and statistical arbitrage. Research suggests that 60 to 80% of all cryptocurrency trades originate from algorithmic or high-frequency strategies.
Automated market makers represent a fundamentally different approach. Uniswap replaces order books entirely with liquidity pools governed by the constant product formula. Instead of professional firms posting quotes, anyone can deposit tokens into a pool and earn trading fees.
The tradeoff is that liquidity providers face impermanent loss — the cost of having their positions rebalanced automatically as prices move. Research by Jason Milionis, Ciamac Moallemi, Tim Roughgarden, and Anthony Zhang introduced the concept of Loss-Versus-Rebalancing, calculating that for an asset with 5% daily volatility, liquidity providers lose approximately 3.125 basis points per day to arbitrageurs exploiting stale AMM prices.
Curve Finance optimized the AMM model for stablecoins with its StableSwap algorithm, while Balancer extended the concept to pools of up to eight tokens in arbitrary ratios. Each design solves different liquidity problems, but none fully replaces the capital efficiency of professional order-book market makers.

The Dark Side: Wash Trading and Federal Enforcement
Crypto market making carries significant controversy. Academic research by Lin William Cong, Xi Li, Ke Tang, and Yang Yang, published in Management Science, estimated that more than 70% of volume on unregulated exchanges is wash trading, with some newly established platforms faking more than 90%.
Bitwise Asset Management told the SEC in 2019 that 95% of volume on unregulated venues appeared suspect.
In Oct. 2024, the FBI revealed Operation Token Mirrors, an undercover operation in which the Bureau created its own Ethereum-based token to bait market makers into committing wash trading. The resulting charges hit multiple firms.
Gotbit Consulting, a Russian-founded market maker, saw founder Aleksei Andriunin indicted for wire fraud after the firm openly offered wash trading services. ZM Quant, a BVI-registered firm, earned over $3 million providing volume creation services.
CLS Global, a UAE-based firm, pleaded guilty after using 30 wallets to execute 740 wash trades on the FBI's token, generating $600,000 in fake volume that accounted for 98% of total trading activity on that token. CLS was fined $428,059, sentenced to three years of probation, and banned from U.S. crypto markets.

Predatory Token Deals That Drain Projects
Perhaps more insidious than wash trading are market-making deals that quietly drain early-stage token projects. The dominant deal structure is the loan option model, in which a project lends 1 to 5% of its token supply to a market maker, who receives call options as compensation.
The risk, documented in a 2025 Cointelegraph investigation, is that some market makers dump the loaned tokens immediately, crash the price, buy back at a discount, and pocket the difference.
Ariel Givner, founder of Givner Law, described the pattern directly, saying she has not seen any token benefit from these arrangements and that the larger firms she has encountered simply destroy charts.
Jelle Buth, co-founder of market maker Enflux, called the loan option model predatory, attributing its dominance to information arbitrage where market makers exploit superior understanding of deal terms.
DWF Labs drew particular scrutiny after a 2024 Wall Street Journal report revealed that Binance's own internal market-surveillance team found the firm had manipulated prices of at least seven tokens. Binance fired the investigator who produced the report within a week.
The cost of hiring a market maker varies widely. Retainer-based arrangements run $4,000 to $7,000 per month per exchange. For token launches requiring exchange listings, total costs can range from $50,000 for a small DEX launch to $1 million or more for top-tier exchange strategies.

What Academic Research Says About Crypto Market Structure
Academic work on crypto market microstructure has matured considerably. David Easley, Maureen O'Hara, Songshan Yang, and Zhibai Zhang at Cornell University found in a 2024 paper that the volume-synchronized probability of informed trading in crypto ranges from 0.45 to 0.47, roughly double the 0.22 to 0.23 levels observed in S&P 500 futures.
This indicates far greater toxicity, meaning informed traders exploit liquidity providers more aggressively in crypto than in equities.
Thomas Dimpfl reached an earlier but consistent conclusion in his 2017 paper on Bitcoin market microstructure, finding that Bitcoin markets show high adverse selection costs. Private information, in other words, significantly drives bid-ask spreads in crypto.
Almeida and Gonçalves reviewed 138 academic papers on cryptocurrency market microstructure for Annals of Operations Research, mapping the field's growth from early price-discovery studies to sophisticated analyses of execution quality and transaction costs.
The consensus across this literature is clear: crypto markets remain structurally less efficient than traditional equity markets, and market-maker quality is one of the primary variables separating functional from dysfunctional trading venues.

What Traders Should Watch For
Coin Bureau suggests that a healthy trading pair should show spreads under 0.15%, volume above $1 million per day, and slippage under 0.5% on a $10,000 test order. Any pair that fails those basic checks carries elevated risk of poor execution.
Favor exchanges with active market-maker programs and transparent fee structures. Avoid newly listed tokens with high reported volume but thin visible order books. The CLS Global conviction showed that 98% of a token's reported volume can be entirely fabricated. Check the order book depth before placing any large trade, not just the last traded price.
The regulatory landscape is also shifting. In Mar. 2026, the SEC and CFTC issued a joint interpretive release classifying major crypto assets as digital commodities, laying groundwork for clearer trading rules that may eventually formalize market-making obligations in crypto as they exist in equities. Until then, the responsibility for evaluating liquidity conditions falls squarely on traders themselves.
