Dark Pools Dominate, Whales Conceal: How Reliable Are Public Market Signals?

The proportion of dark pool transactions has risen to 15%, with institutional liquidity continuously flowing away from public exchanges.

sFOX has released data showing that the volume of cryptocurrency dark pool transactions continues to rise, with a minimal scale in April, reaching 15% of the total monthly transaction volume by June. The company's report on July 30 also mentioned that 77.7% of institutional funds on the platform were matched through over-the-counter (OTC) trading, with only 18.4% flowing to public exchanges. In May alone, the dark pool transaction amount reached $147 million.

Diana Pires from sFOX stated in an interview with CryptoSlate that this represents a structural shift, similar to the transformation experienced by the stock and forex markets years ago.

Why Institutions Choose Cryptocurrency Dark Pools

Large orders placed on public order books leave clear traces. Other traders can identify trading patterns, execute trades ahead of time, or push prices in the opposite direction before orders are filled, increasing trading slippage.

Pires cites institutions like Jane Street and Citadel, which have strong incentives to hide their trading tracks. Once trading patterns are recognized by the market, other participants will engage in targeted reverse trading.

This is also the fundamental reason why an increasing number of cryptocurrency orders are opting for dark pools, OTCs, and platforms that can simultaneously distribute a single order to multiple trading venues for execution.

sFOX alone connects to over 40 exchanges and OTCs, with its institutional clients averaging 14 to 19 channels for transactions each month.

After receiving large orders, OTCs will first split them into smaller orders before distributing them, avoiding direct market volatility from a single transaction.

Pires summarizes the core logic of cryptocurrency dark pools: trading platforms privately accept large positions, then split them into smaller orders sent to exchanges, which almost do not disturb the order book. She believes that when such funds flow into the public market, they help deepen the order book and further narrow the bid-ask spread.

In the past, public order books could reflect the vast majority of real trading activities in the market, but now they only represent a small portion of market transactions. A quiet exchange does not mean that institutions are not trading. Large buyers can accumulate for weeks without placing any visible buy orders; large sellers can also reduce their positions significantly without creating substantial selling pressure on the market.

The Information Advantage of Tracking Whales is Being Actively Eroded

Bitcoin and cryptocurrency traders once had a natural advantage over other market participants: everyone could continuously monitor exchange fund balances, large orders on the order book, and significant on-chain holdings.

Pires points out that dark pools are designed to eliminate this advantage. Trading platforms, OTCs, and brokers can see the underlying flow of funds, and this information is protected by regulatory rules and client agreements, leaving retail investors unaware of whether institutions are buying or selling.

Simple cross-market arbitrage opportunities are also disappearing. Previously, the speed of information dissemination was slower than the flow of funds, allowing investors to buy low on one exchange and sell high on another for profit. Pires states that as primary brokers and aggregation platforms scan dozens of trading venues simultaneously, they complete arbitrage before retail investors can capture price differences, causing such opportunities to shrink year by year.

She predicts that the cryptocurrency trading market will ultimately evolve into a form similar to the stock market: individual investors will no longer directly access exchanges but will do so through brokers, who will seek the best quotes across major trading venues on their behalf.

Retail accounts often struggle to meet the minimum fee thresholds of exchanges, while brokers integrating massive institutional orders can easily meet these standards. Pires believes this gap will continue to drive ordinary traders towards brokers, although this shift will not be enforced by regulation as it is in the stock market.

Two Market Outlook Scenarios

Optimistic Scenario

Order aggregation platforms and mainstream exchanges handle retail orders like institutional orders. Market spreads continue to narrow, slippage decreases further, and large orders breaking through thin markets become less frequent.

Trading opportunities lost from public exchanges shift to other avenues. On-chain and DeFi markets still retain public data on large holdings, providing avenues for traders looking to speculate on market fluctuations; regulated and compliant trading markets will exhibit smoother trends.

Pessimistic Scenario

For ordinary traders with limited capital, the speed at which trading transparency disappears far exceeds the speed at which expected trading optimizations are realized. Retail and medium-sized investors will completely lose the ability to judge institutional fund movements.

Spread optimization and quality order routing services will still only cater to large clients that meet capital thresholds and can connect with primary brokers and aggregation platforms. The signals from public exchanges will continue to weaken, and participants relying on monitoring exchange order books will be the first to feel the changes.

Regardless of the market direction, traders need to adjust their trading habits: do not treat the volume of a single exchange as a reference for the overall market; compare the comprehensive trading costs of different channels before considering exchange listing fees; when market depth is insufficient, try to use limit orders to prevent market orders from impacting prices.

Beneath the seemingly calm order book, there may be large-scale institutional trading lurking.

As the cryptocurrency market matures, trading experiences continue to improve, but the difficulty of interpreting the market is increasing. Retail investors encounter fewer sudden impacts from whale movements, yet they also find it challenging to observe the most valuable movements of major funds.
