Crypto OTC trading has moved from a niche execution channel to a major institutional market-structure layer. Instead of relying only on public exchange order books, funds, market makers, payment companies, treasuries, and high-net-worth traders increasingly use private execution workflows for large trades, settlement flexibility, and reduced market impact.
This brief explains the latest 2025–Q1 2026 statistics, why OTC volume is difficult to measure, and what the numbers suggest about institutional adoption, stablecoin settlement, and execution quality. The key theme is clear: crypto OTC is not a fully transparent exchange-style market, but reported platform and desk data offer useful signals about where institutional digital asset trading is heading.
The following figures should be read as directional indicators from platform and desk samples, not a complete census of the private OTC market. Crypto OTC activity is private, fragmented, and usually measured through proprietary platform data, desk-reported data, or institutional surveys.
Key statistics from recent reported samples include:
The strongest interpretation is not that the entire OTC market is a single, precisely measurable dollar amount. Rather, available samples show a market becoming more institutional, more stablecoin-dependent, and more execution-quality focused.
Crypto OTC trading means buying or selling digital assets through a privately negotiated trade rather than placing an order directly on a public exchange order book.
An OTC trade may be executed through an OTC desk, broker, market maker, ECN, principal desk, agency desk, or request-for-quote workflow. Typically, a buyer or seller requests a quote for a specific asset, trade size, side, and settlement method. The desk or liquidity provider then quotes a price, and the trade is confirmed and settled bilaterally or through agreed infrastructure.
Institutions use OTC trading for several practical reasons:
For first-time readers, the simplest framing is this: OTC is a private execution channel built for size, discretion, and operational control.
Because OTC is decentralized and opaque, this article uses reported samples as market-structure indicators rather than a complete market census.
OTC trading does not happen on one public order book. It is fragmented across desks, bilateral relationships, ECNs, brokers, custodians, market makers, and private liquidity networks. Many trades are private by design, so public datasets undercount activity unless desks or platforms report aggregated data.
Different data sources answer different questions:
This is why credible OTC analysis should avoid unsupported claims such as “the OTC market is exactly X dollars.” The better approach is to compare reported samples over time and look for consistent signals.
The recent growth arc is best understood as a timeline.
The shift looks more like maturation and normalization than a collapse. After a major expansion cycle, institutional flows appear to have become more selective, more risk-aware, and more execution-focused. Growth compressed, but it remained positive.
OTC demand is not just “big whale trades.” It reflects a broader institutional need for controlled execution, settlement reliability, governance, and counterparty management.
Common OTC users include:
Broader survey data supports this institutionalization. EY-Parthenon and Coinbase surveyed more than 350 institutional investors globally in January 2026, including asset managers, asset owners, family offices, private banks, hedge funds, and VC firms. In that survey, 73% of respondents planned to increase digital asset allocations in 2026.
Importantly, the same survey emphasized that institutions are pairing allocation intent with more disciplined risk, liquidity, position-sizing, and governance practices.
Crypto market structure is becoming more multi-venue. CEXs, DEXs, and OTC desks each solve different execution problems.
In Q1 2026, Finery reported OTC volume up 43% YoY. Over the same period, it reported top-20 DEX volume up 39% YoY and top-20 CEX volume down 45% YoY. Finery described this as a continuation of venue rebalancing observed in 2025.
This does not mean centralized exchanges are obsolete. It suggests institutional trading is becoming more multi-venue, with OTC rails gaining relative importance for large-block execution where discretion, reduced market impact, and capital efficiency matter.
BTC remains central to institutional OTC activity, but ETH gained share sharply in Q1 2026 in Finery’s sample.
In Q1 2026, ETH and BTC together represented 74% of institutional OTC volume, up from 62% in Q1 2025. ETH’s share rose from 20% to 41% year over year, while BTC’s share moved from 42% to 33%.
Finery cautioned that ETH’s expansion is still early to interpret conclusively. Possible drivers include Ethereum layer-2 infrastructure, tokenization use cases, and ETF-related flows. Overall, the quarter looked more like a reweighting within major assets than broad-based expansion across the full token spectrum.
The reader takeaway is straightforward: institutional OTC liquidity is concentrated around majors, not spreading evenly across all crypto assets.
Stablecoins are no longer just trading pairs. They are becoming settlement infrastructure.
In 2025, stablecoins represented 78% of all OTC transactions processed through Finery’s liquidity network, up from 26% in 2023. Finery also reported 119% YoY stablecoin volume growth in 2025.
The trend continued into 2026. In Q1 2026, Finery reported stablecoin OTC volumes up 59% YoY. It also reported that crypto-to-stablecoin flows rose 82% YoY, while crypto-to-fiat and crypto-to-crypto conversions contracted. Stablecoins accounted for 82% of total trades in Finery’s Q1 2026 sample, up from 76% in Q1 2025.
The operational reason is clear: stablecoins help OTC desks and institutions settle in a dollar-linked or fiat-linked unit without always returning to traditional bank rails. They can support 24/7 settlement and faster movement of value.
However, stablecoins also introduce risks, including reserve quality, depeg events, issuer exposure, chain risk, redemption constraints, and jurisdictional uncertainty. Coinbase and EY’s 2026 survey also found that stablecoins have moved beyond trading facilitation, with institutions using or considering them for cash management, money movement, and near-real-time settlement.
Stablecoin share is therefore one of the most important OTC indicators to watch because it connects trading liquidity, settlement speed, and institutional operating models.
Modern crypto OTC execution is more than a trader calling a desk for a quote. Institutions now use a range of workflows:
Wintermute reported that its OTC options activity more than doubled YoY in 2025, with year-end notional volumes almost four times higher than at the start of the year and trade counts more than twice as high.
Because this is proprietary, desk-specific data, it should not be treated as a universal market total. Still, it suggests OTC is becoming not only a spot access channel, but also a risk-transfer and portfolio-construction layer.
The practical problem OTC solves is execution quality at size. Large public orders can consume multiple levels of an order book, creating slippage between expected and actual execution price. They can also reveal trading intent, invite adverse price movement, or create market impact before the full order is complete.
For institutions, OTC evaluation is therefore not only about headline price. It includes total execution cost, certainty, settlement speed, counterparty quality, and operational risk.
The table below is illustrative and hypothetical, not market data.
A simple calculation shows why this matters. If a $25 million order suffers 30 bps of all-in execution cost, the cost is $75,000. If improved OTC execution reduces cost by 10 bps, the savings are $25,000.
That is why institutions often care as much about process, liquidity sourcing, and settlement reliability as they do about the first quoted price.
OTC trading offers benefits, but institutional users need a rigorous risk checklist.
Key risks include:
Coinbase and EY-Parthenon reported that 49% of surveyed institutions strengthened their emphasis on risk management, liquidity, and position sizing. The same survey summary reported that 66% cited regulatory compliance as a key custodian-selection factor in 2026, up from 25% in 2025, and 66% cited security/key-signing protocols, up from 8% in 2025.
EY’s version of the survey also noted that risk, regulation, and custody security have moved from “considerations” to “decision drivers.”
The practical takeaway: OTC desk selection should include pricing quality, liquidity access, settlement process, counterparty controls, custody compatibility, compliance support, and operational resilience.
Crypto OTC is becoming a core institutional market-structure layer for large-block execution, stablecoin settlement, and risk-managed trading.
Growth is no longer uniformly explosive. 2024 and 2025 showed triple-digit expansion in Finery’s sample, while Q1 2026 showed slower but still positive 43% YoY growth. Activity appears concentrated in BTC, ETH, stablecoins, regulated access products, and more disciplined execution models.
The next phase is likely to be shaped by liquidity concentration, stablecoin infrastructure, risk governance, and regulatory clarity. For firms evaluating the space, the most useful indicators are:
For market participants, including OTC desks and institutional execution providers such as Fuze Finance, the broader conversation is increasingly about trust, liquidity access, compliant settlement, and resilient execution infrastructure rather than trade size alone.
Crypto OTC trading is best understood as an institutional execution layer, not a fully transparent exchange-style market. Its size is difficult to measure because activity is private, fragmented, and often visible only through proprietary platform or desk samples.
Still, the available statistics are meaningful. Finery’s sample showed 2025 spot OTC volume up 109% YoY, while Q1 2026 volume still rose 43% YoY despite slower market growth. Stablecoins reached 78% of 2025 OTC transactions and 82% of Q1 2026 trades, highlighting their growing role as settlement infrastructure. BTC and ETH represented 74% of Q1 2026 institutional OTC volume, showing strong concentration around major assets.
Before evaluating an OTC desk or execution partner, readers should track stablecoin settlement share, BTC/ETH concentration, venue shifts between OTC, CEXs, and DEXs, OTC options growth, and regulatory or custody developments. These indicators will define the next phase of institutional crypto trading.
