How deep is the book?

Order book depth, spreads and venue concentration determine what a market costs to use. On the 2026 measurements, digital asset execution on major pairs is closer to established markets than most descriptions of the asset class assume — with important qualifications further down the curve.

Depth is the amount of resting liquidity available within a given distance of the mid price. It answers the practical question: how much can be transacted before the price moves against the order. It is more informative than volume, which counts trades that have already happened, and more informative than market capitalisation, which counts supply that may never be offered.

Sub-basis-point spreads on bitcoin and ether place major digital asset pairs in the same range as liquid foreign exchange and large-cap equities.¹ Solana at roughly one basis point is five to eight times wider, which is consistent with its market capitalisation rather than indicative of a problem.

Venue dispersion is a real cost

Digital assets trade across many venues without a consolidated tape or a national best bid and offer. Prices and spreads differ between venues at any moment, and those differences are large enough to matter on institutional order sizes.

Reported dispersion in early 2026 had Bybit typically widest on perpetual contracts and Binance and OKX tightest on USDT pairs, producing what analysts described as venue selection value of 0.5 to 1.0 basis points on large orders.¹ That is a small number per trade and a significant one annualised across a turnover-heavy book.

The absence of consolidated market data is one of the clearer remaining structural differences from regulated equity markets. It creates a persistent, mechanical advantage for participants with the infrastructure to route across venues, and a corresponding disadvantage for those without.

Where the open interest sits

Two features stand out. Concentration is high: a single venue carried more than a third of global open interest.¹ And the composition is unusual — more than 96% of open interest sits in perpetual contracts rather than dated futures, a ratio that has no parallel in conventional derivatives markets, where dated contracts dominate.

The growth of Hyperliquid to roughly $9 billion is notable as the first on-chain venue to reach materiality in this ranking, indicating that decentralised derivatives infrastructure has become viable at institutional scale rather than remaining a retail curiosity.

Ninety-six per cent perpetuals is a structural fact with consequences: funding becomes the dominant carry mechanism, and positioning data is available continuously rather than at expiry.

What the perpetual structure implies

Because perpetual contracts never expire, they require funding payments to stay tethered to spot, and those payments are published continuously. This gives digital assets a positioning signal that conventional markets lack: a live, public measure of which side is paying to hold exposure.

Funding readings across 2026 illustrate the range. Seven-day average funding in January sat at +0.32% for bitcoin, +0.40% for ether and +0.48% for Solana — annualised rates of roughly 44%, 55% and 66% respectively, described at the time as positive but compressed from earlier readings.¹ By early September the rate had fallen to 0.0028% per eight hours, approximately 3.1% annualised.²

Between those two points sat an inversion: funding stayed negative for 46 consecutive days between approximately 1 March and 15 April, the longest such stretch since the period following the FTX failure in November 2022.³ A carry position that collects in positive funding pays during an inversion, which makes the sign of this number a direct input to the economics of market-neutral strategies rather than an incidental cost.

Cross-venue arbitrage indicates fragmentation

Funding rate spreads between venues in early 2026 reached 6.37% for WLFI, 2.65% for Solana and 2.27% for UNI — the same instrument priced materially differently in different places.¹ Spreads of that size persist only where capital cannot move freely between venues, whether because of collateral requirements, withdrawal times or counterparty limits.

This is the other side of the venue selection advantage noted above. Fragmentation creates opportunity for participants able to hold margin in multiple places and cost for those who cannot, and it is a reasonable proxy for how far the market remains from full integration.

Credit conditions

On-chain lending provides an unusually transparent view of leverage in the system. As of the January 2026 reading, lending protocols held approximately $58 billion in total value locked, with Aave v3 on Ethereum accounting for around 79%, or $46 billion. Utilisation ran at 35–36% against roughly $21 billion borrowed, and seven-day liquidations were minimal despite active price volatility.¹

Utilisation in the mid-thirties indicates substantial unused borrowing capacity, and near-zero liquidations through a period of significant price movement indicates that positions were, in aggregate, conservatively collateralised. These conditions persisted through the June trough without producing disorderly liquidation, which is the observation that most distinguishes 2026 from 2022.

Reading the picture as a whole

The measurements describe a market that is deep and cheap to trade at the top, thinner and more expensive as capitalisation falls, structurally concentrated across a small number of venues, fragmented enough that the same contract prices differently in different places, and carrying conservative leverage on its transparent credit rails.

That is a recognisable profile. It resembles a maturing market with incomplete infrastructure rather than either a fully institutional one or a speculative venue. The specific gaps — no consolidated tape, high venue concentration, persistent cross-venue dispersion — are the kind that market structure regulation and competition tend to close over time, and are worth watching as the measures of whether that is happening.
