Solana Surpasses Ethereum in Monthly DEX Volume for the First Time

Solana processed $36.87 billion in decentralized exchange volume in May 2026, surpassing Ethereum's $31.59 billion for the full calendar month, according to data reported by 247 Wall St. The result extends a trend that has been building since at least November 2025 and marks the first time Solana has beaten Ethereum on a monthly basis at this scale.

Alongside the volume figure, Solana captured 32.6% of global stablecoin transfers in May, according to 247 Wall St., reflecting the network's growing role in everyday on-chain value movement beyond speculative trading.

How Jupiter and Raydium Built Solana's DEX Lead

The structural case for Solana in DEX trading is cost: a transaction costs $0.00025 on Solana versus $0.50 to $3.00 for a comparable swap on Ethereum's base layer, per 247 Wall St. That gap does not merely attract retail traders. It changes which trading strategies are viable at all. High-frequency rotations, small-position arbitrage, and memecoin speculation require sub-cent economics, and Solana provides them where Ethereum mainnet cannot.

Jupiter JUP$0.315-3.5% (Jupiter) sits at the center of Solana's DEX architecture. The aggregator routes roughly 95% of all aggregator-mediated trades on the network and accounts for more than half of total Solana DEX volume, according to industry analysis. When a user swaps on Solana (through a wallet interface, a bot, or a third-party app), Jupiter is typically the routing layer finding the best price across liquidity venues in real time.

The primary liquidity venue that Jupiter and other aggregators draw on is Raydium RAY$1.92+3.2% (Raydium), which combines an automated market maker with an order book for tighter pricing than pure AMM designs. Orca ORCA$1.75+2.2% (Orca) holds second or third position in Solana DEX liquidity, regularly carrying $500 million to $800 million in total value locked, per industry tracking. Together these three protocols define the shape of Solana's DeFi trading layer.

The momentum behind the May overtake had been building for months. In January 2026, Solana-based DEXes processed approximately $117 billion against Ethereum's $52 billion, though that figure encompasses a broader range of activity including leveraged instruments. By Q1 2026, Solana held roughly 30.6% of total DEX market share on a spot basis, according to industry data cited in analyst coverage, and the May monthly comparison confirms the trend continued through mid-year.

Where Ethereum Still Leads: TVL, Developers, and Institutional RWA

The DEX volume comparison is one dimension of a larger picture, and Ethereum leads the others by wide margins.

Ethereum holds $45.5 billion in DeFi total value locked as of May 2026, representing approximately 53% of the global DeFi market, per DeFiLlama data cited by 247 Wall St. Solana's TVL sits at roughly $7.6 billion. Deep lending, derivatives, and institutional structured-product infrastructure remains concentrated on Ethereum, where the liquidity pools have had years to accumulate.

Ethereum also leads on developer activity: 31,869 active developers versus Solana's 17,708, according to 247 Wall St. Tokenized US Treasury products on Ethereum reached a record $8 billion in May 2026, doubling within six months, as institutions including JPMorgan, BlackRock, and Franklin Templeton continue building on top of Ethereum infrastructure.

Solana's stablecoin supply has grown to over $13 billion, with USDC accounting for roughly 75% of that total, but Ethereum mainnet and its L2 ecosystem still hosts the dominant share of institutional stablecoin liquidity.

The DEX overtake is most accurately read as Solana winning the high-frequency, consumer-facing, and speculative trading category. It does not displace Ethereum from institutional capital management.

Alpenglow Upgrade and the Next Phase of Solana DEX Competition

The Alpenglow upgrade entered a community test cluster on May 11 and is now in validator testing. Solana co-founder Anatoly Yakovenko said at Consensus Miami 2026 that Alpenglow could reach mainnet as early as Q3 2026 if testing proceeds on schedule. The upgrade targets transaction finality of 100 to 150 milliseconds, down from the current 12.8 seconds, per 247 Wall St.

Finality at sub-150ms would make Solana faster than most existing payment infrastructure, opening the door to on-chain order books and tokenized financial products that settle as fast as they trade. For DEX trading specifically, latency-sensitive strategies that depend on near-instant settlement confirmation become viable at that speed in ways they are not today.

That upgrade is arriving as JUP (JUP) and RAY (RAY) sit at the center of a network already processing more monthly trading activity than Ethereum. The infrastructure assembled during the meme coin era (fast, cheap, deeply integrated) is now the active layer for the broader market.

Ethereum's Glamsterdam upgrade, targeting Q3 2026, aims to push throughput higher and cut base layer fees. Whether it closes the cost gap enough to reclaim DEX volume share is the open question heading into the second half of 2026.
