Perpetual DEX Open Interest Rises 76% to $24 Billion as Q3 Volume Falls

What the quarterly numbers actually say

PANews reports two changes in opposite directions: open interest increased and volume decreased. Treat the first as the report's measure of outstanding positions and the second as activity over the quarter. Calling both “money flowing into DEXs” would remove the distinction that makes this report useful. The OI and volume comparison.

All figures in the table come from PANews' report citing unfolded. The table keeps missing comparisons empty instead of reconstructing them from unrelated figures.

For someone holding a perpetual contract, the useful question is narrower than whether the whole sector grew. Look at the instrument you hold. Record its outstanding positions, recent volume and the price available for your intended order size. The sector total provides a reason to make those checks; it does not answer them for every market.

The previous quarter implied by the rounded figures

Simple arithmetic helps put the reported changes into scale. If $24 billion represents a 76% increase, the implied comparison value is $24 billion divided by 1.76, or approximately $13.64 billion. The implied increase is therefore about $10.36 billion. These are calculations from PANews' rounded inputs, not additional observations of the previous quarter. The inputs for this calculation.

For volume, a 16% decline leaves 84% of the comparison value. Dividing $1.4 trillion by 0.84 gives about $1.67 trillion. Subtracting the reported Q3 amount gives an implied decline of approximately $0.27 trillion. Preserve the approximate signs when quoting those results because the source itself rounds the starting figures.

The arithmetic illustrates the scale of the divergence. Outstanding positions rose by roughly three quarters while trading activity shrank by roughly one sixth. It does not tell us how much collateral was deposited, how many people entered the market, or how many positions were profitable. Those are different questions for which the brief report supplies no figures.

Avoid turning the implied previous-quarter values into a precise historical series. A chart built from those two calculations would need to label them as estimates derived from rounded inputs. For a comparison with another data provider, first obtain that provider's coverage and measurement dates; otherwise the apparent difference could reflect different definitions.

Hyperliquid's reported share needs its own denominator

Hyperliquid's roughly $13 billion in open interest is the largest platform amount named in the report. PANews describes that amount as more than double its earlier level and gives the platform about 53% of the sector's open interest. Those statements should travel together with their attribution. Hyperliquid's reported position.

Dividing the two rounded dollar figures, $13 billion by $24 billion, produces about 54.2%. That is not exactly the reported 53%. The short report does not provide unrounded inputs or enough methodological detail to reconcile the difference. Use “about 53%, according to the report” when describing the published share, and label 54.2% only as arithmetic on rounded numbers.

A reader comparing market-share headlines should check that the metric is open interest in both cases. A volume share would answer another question. The report's 53% figure cannot establish Hyperliquid's share of quarterly volume, users, collateral or profits. None of those shares appears in the opened report.

The trade[xyz] figure also deserves care. PANews identifies it as a HIP-3 deployer and reports about $3.9 billion of open interest. The brief does not give a detailed reconciliation of that figure with the Hyperliquid aggregate. Do not add $3.9 billion to $13 billion and present the result as a separately verified total. The trade[xyz] figure and description.

Fast growth outside the headline platform

PANews reports open-interest growth of about 78% for Variational, 107% for Lighter and 66% for Aster. It does not provide their absolute open-interest amounts in the brief. The growth-rate ranking is therefore Lighter, Variational and Aster among those three named figures; it does not establish their ranking by market size. The other reported growth rates.

That distinction affects a venue comparison. A 107% increase means the reported measure more than doubled, but the percentage alone supplies no dollar amount. Before treating the fastest-growing venue as the largest, obtain the starting and ending values on a comparable basis. The same discipline applies to the 78% and 66% figures.

PANews says growth mainly came from the launch of new markets. Attribute that explanation to the report. Its short text does not identify how much of the sector's increase came from each new contract, or give a contract-by-contract launch timeline. It would be premature to assign the whole increase to a particular asset category or a single product. The report's explanation of the increase.

For a trader interested in one of those venues, begin with the exact market under consideration. Write down the instrument name and settlement asset displayed in the product information. Then inspect the order you intend to place. A quarterly growth percentage cannot substitute for a current quote or establish that your account can access that market.

Turn the report into a position review

Start with an existing position if you have one. Record its contract name, position size and the account balance shown on the same screen. Keep those figures beside the report's sector totals instead of mixing them into a single number. This makes the review about the exposure you actually hold.

Next, request or inspect a quote for the amount you plan to trade. Compare the displayed price with the order book at that size. If you split the order, review each part on its own terms. The quarterly volume total gives no execution quote for your order, and the OI total gives no promised exit price.

Use the funding-rates board to identify the contract and observation time you want to investigate. Check those entries against the product screen before calculating a holding cost. This article does not quote a current funding rate: the quarterly report contains none. Save the rate and interval shown for your actual instrument if you need to compare holding costs.

Readers reviewing an existing leveraged position can also open the liquidations board. Check the market and time window displayed before connecting any observation to the position in your account. The Q3 report supplies no liquidation total, liquidation price or margin requirement for an individual trader. Those items need their own current data.

If your reason for moving venues is the reported growth in open interest, make the comparison at the same order size. Keep a record of the quote, available product terms and account eligibility on each venue you are considering. Leave any field blank that you cannot confirm. The report gives a starting list of venues to investigate, without establishing a winner for that transaction.

Funding requires a separate calculation

Hyperliquid's official Funding documentation describes payments between the two sides of a perpetual contract and says funding is paid hourly. It also specifies that the payment at the end of an interval is position size multiplied by oracle price and funding rate. That gives an existing position holder a concrete calculation to check against the account record. Source: Hyperliquid Docs, Trading, Funding, opened for this article.

The documentation distinguishes the oracle price used in that calculation from the mark price. When reviewing a funding entry, take the price basis from the stated formula. Copying a different price from another part of the interface could produce a different result. Record the direction of payment as well as its amount before comparing it with the balance change.

On Hyperliquid, choose the exact perpetual contract you hold and write down its funding rate together with the next hourly funding time. Keep the sign of the rate. Use that contract's displayed rate when checking which side pays; the sector's 76% OI increase supplies no funding rate for this calculation.

To check a completed Hyperliquid funding payment, take the position size, oracle price and funding rate for that interval and multiply them. Compare the result and payment direction with the balance entry. If your record lacks an input, retrieve that interval's account record before treating a difference as a fee change. These checks follow the official Funding documentation's payment formula.

For HIP-3 perpetuals, the same official page describes a different premium formula that allows deployers to express a wider range of funding behavior through the funding-rate multiplier and interest rate. A reader investigating the reported trade[xyz] growth should therefore inspect the exact contract's funding terms. The quarterly open-interest figure does not specify those settings, and a rate seen on another contract cannot establish them.

What would make the next update useful

A fuller release of the underlying dataset would help answer several questions: the exact measurement date for OI, the universe of included venues, the treatment of HIP-3 markets and the unrounded numbers behind market shares. Those details would make cross-platform comparisons easier to reproduce. PANews' short report does not supply that methodology.

For the new-market explanation, look for absolute OI and volume by contract, measured over comparable periods. A list of launches alone would not show the contribution of each market. For the platform growth rates, look for the starting dollar amounts as well as the percentages. That would allow a reader to separate rapid growth from a small base and a large increase in outstanding exposure.

The opened numerical report attributes its figures to unfolded. We did not obtain a separate underlying dataset that independently reproduces those totals. Keep that attribution when sharing the figures. For a current trade, return to the exact contract, quote and funding interval you intend to use; the quarterly comparison remains background for that check.
