The DEX spot volume ratio reached 24% of covered centralised exchange volume in July 2026, the highest reading in The Block’s current data series, according to The Defiant, which cited The Block’s methodology. The figure held between 18% and 21% through the first half of 2026 before jumping in July.
The calculation divides monthly DEX volume by volume across a selected group of centralised exchanges, using the top 30 DEXs by volume from DefiLlama. That means 24% is not a share of all global spot trading. It means DEX activity equalled roughly 24% of the covered CEX total, a narrower denominator.
A softer CEX quarter made the DEX spot volume ratio look bigger
Talos reported that total exchange spot volume fell 28% quarter-over-quarter to $2.32 trillion in Q2 2026. CoinGecko’s Q2 2026 Crypto Industry Report put the decline at 27.9% for the top 10 CEXs specifically, where volume dropped from $2.70 trillion to $1.95 trillion, a narrower exchange set than Talos tracked, so the two figures are not directly comparable.
A falling denominator mechanically lifts the DEX ratio even when DEX absolute volume is flat. That context matters when reading July’s print as a structural shift rather than a cyclical artefact.
Talos also noted that Q2 futures volume fell 11.6% quarter-over-quarter to $12.32 trillion, and the spot-to-futures ratio compressed from 0.23x to 0.19x. Derivatives positioning increased relative to spot demand across centralised venues, which gives the DEX spot share gain a slightly different character: traders appear to have been moving spot activity permissionlessly while keeping leveraged exposure on centralised infrastructure.
On the DEX side, Hyperliquid added another dimension. Its futures volume market share grew to approximately 4.5% in Q2 2026, per Talos, while DefiLlama shows Hyperliquid L1 running approximately $6.26 billion in trailing 30-day spot DEX volume, placing it beyond the four chains most commonly cited in the headline rankings.
Robinhood Chain’s Uniswap deployment drove July’s new activity
Robinhood Chain, a Layer 2 network built by Robinhood Crypto on Arbitrum Orbit infrastructure, launched its public mainnet on 1 July. Uniswap Labs confirmed that Uniswap v2, v3, v4 and UniswapX went live on the network the following day, covering crypto assets and Robinhood Stock Tokens through its web app, wallet and API.
The network moved quickly up the volume rankings. Approximately two weeks after launch, Robinhood Chain ranked third among all chains by 24-hour DEX volume at $811 million, trailing only Solana at $1.21 billion and BNB Smart Chain at $1.05 billion, per DefiLlama data reported by BeInCrypto. Ethereum sat below it at that snapshot.
Over the trailing 30 days to 2 August, DefiLlama’s chain rankings listed Solana at $49.86 billion, BNB Chain at $31.04 billion, Ethereum at $28.84 billion, Base at $22.38 billion and Robinhood Chain at $14.48 billion. Uniswap led all individual DEXs with $52.04 billion in trailing 30-day volume, ahead of PancakeSwap at $17.59 billion and PumpSwap at $17.3 billion.
Uniswap accounted for roughly 99.5% of Robinhood Chain’s seven-day DEX volume during peak activity. Daily volume averaged around $690 million over a representative seven-day window and peaked at $943.6 million on 11 July. The Stock Tokens were available in more than 120 countries but excluded US users. Early activity included memecoins alongside tokenised equities, which is the pattern that typically produces strong launch-week numbers followed by a step-down once speculative rotation fades.
Uniswap Labs launched Pools.trade on 5 August 2026, a token launchpad built specifically for Robinhood Chain, per the Uniswap Labs products blog. That provides a mechanism to seed new liquidity on the network beyond the initial Stock Token and memecoin activity.
The “record” label carries a caveat. The Block published 25% for May 2025 and 29% for June 2025 in earlier reports, both above July 2026’s 24%. Those historical readings may reflect different exchange coverage or volume-filtering adjustments in an older version of the series. The current dashboard does not publicly reconcile the difference. July can be described as the highest reading in the current cited series; calling it an uncontested market-wide record goes beyond what the methodology disclosures support.
The August reading will show whether the DEX spot volume ratio holds near 24% once Robinhood Chain’s novelty effect normalises and whether Solana, Ethereum and Base can sustain their current 30-day pace without a recovery in CEX spot volumes doing the opposite, compressing the ratio back toward the 18%–21% range that characterised the first half of the year.
