Readers can compare claims about the biggest crypto market makers only by defining what “biggest” means and checking each figure’s source, period, market coverage, and method. Firm-wide scale, trading activity, and liquidity on a particular venue answer different questions. If the evidence does not measure the same thing on the same basis, it does not support a single ranking.

What market makers do in crypto markets

For comparison purposes, a market maker is a participant associated with supplying buy and sell interest in a market. The label alone does not establish how much liquidity a firm makes available, which assets or venues it covers, or whether a particular trade can access that liquidity. Those questions require evidence tied to the relevant market and observation.

Keep market making distinct from operating an exchange. A centralized crypto exchange commonly records customer orders and executed trades in an internal order book. Some exchange operators may also combine functions such as proprietary trading, lending, token issuance, and custody, but not every operator offers every function. An operator’s aggregate activity therefore should not automatically be read as a pure measure of market-making activity. source source

A firm’s presence in a market, or its statement that it makes markets, also does not establish the quality of liquidity available to every participant. Market liquidity can reflect the time and expense of buying or selling, including spread, transaction cost, price impact, and immediacy. These are separate dimensions, and a firm name or broad scale label does not describe all of them. source

What does “biggest” measure?

“Biggest” is not a metric by itself. It could refer to an overall firm measure, activity in a defined crypto segment, or liquidity associated with a particular asset and venue. Each category addresses a different question. A firm-wide measure does not, by itself, show crypto-specific activity; an activity figure does not establish the liquidity available in one market.

Commonly discussed measures also capture different things:

  • Trading activity refers to activity over a period. A useful comparison needs to identify the included assets, venues, entities, units, and calculation method.
  • Quoted spread refers to the gap between displayed buying and selling prices. It does not by itself show how much can be traded at those prices or the cost of a larger order.
  • Quoted depth concerns displayed amounts at specified prices or price ranges. It needs a venue, asset, observation time, and method to be interpretable.
  • Market coverage identifies which markets a figure includes. It does not show the amount or quality of liquidity in each market.

These labels are useful only when the underlying definition and data are available. A figure without a reporting period, asset set, venue set, units, and methodology cannot support a like-for-like comparison. A broad total and a venue-specific observation should not be treated as competing estimates of the same thing.

Evidence for comparing biggest crypto market makers

Start with the exact claim. Is it about a firm’s overall scale, its activity in crypto, or liquidity on a named venue? State the question before collecting figures so the comparison does not shift between unlike measures.

For each figure, record its source and what that source actually measures. An attributable company disclosure documents what a firm says about its own activity; it is not, by itself, independent confirmation. Independently documented data may provide a different basis for assessment, but it still requires a clear definition, scope, and method. Describe the source accurately and do not infer more than it reports.

A comparison record should include:

  1. Metric and units: What is counted, and in what units?
  2. Time period: Does the figure cover a stated interval or describe one point-in-time observation?
  3. Market scope: Which assets and venues are included? Is the measure firm-wide or crypto-specific?
  4. Source and method: Is the figure self-reported or independently documented? If the method is disclosed, what does it count?
  5. Comparability gaps: Are the definitions, coverage, or reporting periods different or missing?

Where the information is available, check whether an activity figure is gross or net and whether it covers a firm broadly or only crypto. If the source does not specify, record that as unknown instead of assuming an answer. A count of supported markets or a broad activity measure is not a substitute for evidence about liquidity quality.

When figures cover different periods, assets, venues, or methods, present them as separate observations and make the differences visible. A missing, stale, or insufficiently defined disclosure creates uncertainty; it is not evidence that one firm is larger, smaller, or absent from a market.

Limits and risks in market-maker comparisons

Liquidity observations are bounded. Market liquidity reflects multiple dimensions and changes with transaction size and market conditions. A displayed spread or amount observed at one moment therefore does not establish what would be available for every order size, across all venues, or at another time. Keep venue-level evidence tied to the market and observation it actually covers. source

A scale measure also cannot, on its own, establish solvency, reliability, execution quality, independence, or recoverability. Those are separate claims and require evidence suited to each question. Apply the same restraint to claims about regulation, tax, compliance, security, recovery, availability, fees, or yields: without current, attributable evidence that covers the relevant service and scope, omit the claim rather than infer it from a firm’s size or activity.

Business roles can overlap, which affects what aggregate disclosures mean. An exchange operator may combine several activities, while another may perform only some of them. If a disclosure does not separate those activities, readers cannot safely treat its total as a standalone measure of market making. source

There is another reason not to equate a firm’s reported presence with available liquidity: market structure may be more concentrated in practice than a system’s stated architecture or ethos suggests. That general observation does not establish the concentration level for any specific market maker, asset, venue, or time period. A specific conclusion needs evidence scoped to that case. source

A practical comparison checklist

Use this sequence when reviewing a claim:

  1. Define the question. Decide whether the comparison concerns firm-wide scale, crypto activity, or liquidity in a specific market on a specific venue.
  2. Select a matching measure. Do not compare an activity figure over a period with a point-in-time depth observation, or a firm-wide total with a venue-specific figure.
  3. Fix the scope. Record the period, assets, venues, units, and method for every observation.
  4. Label the evidence. Distinguish company-reported statements from independently documented data and state what each source does not establish.
  5. Note the limits. Flag missing definitions, different scopes, stale observations, and measures that cannot be compared directly.

The appropriate output is a qualified comparison, not a definitive league table or recommendation. If available disclosures do not support a like-for-like assessment, state that clearly. The absence of comparable evidence is a limit on what can be concluded—not a reason to fill gaps with assumptions.
