Sui Posts $760 Million in Daily Volume as Layer-1 Momentum Builds in May
Sui (SUI) posted $760 million in 24-hour trading volume on May 18, placing it among the highest-volume layer-1 networks on a day when the broader cryptocurrency market sold off sharply. Bitcoin dropped to $76,900 and total market liquidations hit $814 million.
SUI’s market capitalization stood at $11 billion, placing it 26th globally. The token’s volume-to-market-cap ratio outpaced most peers in the same session.
Volume Composition and Network Activity
Sui’s $760 million in daily volume reflects both spot and derivative activity across centralized and decentralized venues.
The Sui network supports a growing decentralized finance ecosystem, with lending, borrowing, and automated market-maker protocols built on its native Move programming language. An automated market maker, or AMM, is a type of decentralized exchange that uses mathematical formulas rather than order books to price trades.
Sui’s AMM ecosystem attracted significant capital inflows through April and May 2026 as developers deployed new liquidity pools. The combination of on-chain decentralized finance activity and centralized exchange speculation contributed to the high volume figure on May 18.

What Sui Is
Sui is a layer-1 blockchain, meaning it is a base-layer network with its own consensus mechanism and native token, distinct from layer-2 solutions that settle transactions onto an existing chain.
Mysten Labs, a company founded by former Meta engineers, developed Sui. The network uses the Move programming language, originally designed for the Diem project, which prioritizes safe asset ownership and parallel transaction execution.
Sui launched its mainnet in May 2023. It competes with Solana (SOL), Aptos (APT), and other high-throughput layer-1 networks for developer attention and liquidity.
The network’s parallel execution model allows it to process transactions without the sequential bottlenecks that affect older blockchains.

Background
Sui’s native token SUI launched at $0.10 at mainnet open in May 2023. It reached $1.70 during the broader market recovery in late 2023 and climbed further in 2024 as Move-based chains attracted developer migration from Ethereum and Solana.
By early 2026, Sui had crossed $4 and established itself as a top-30 asset. The May 18, session saw SUI trading near the $4.20 range before the broader sell-off applied downward pressure.
Sui’s volume trend has been consistently strong through Q1 and Q2 2026, supported by DeFi total value locked that grew from under $500 million in mid-2025 to over $2 billion in May 2026.

How Sui Compares to Solana
Solana (SOL) remains the dominant high-throughput layer-1 by total value locked and daily active users. Sui’s advantage lies in its object-centric data model, which handles complex asset ownership scenarios, such as non-fungible tokens and multi-party transactions, more efficiently than Solana’s account model.
Developers building gaming, social, and real-world asset applications have cited this distinction as a reason for choosing Sui. In May 2026, Sui’s daily transaction count has regularly exceeded 50 million, a figure that rivals Solana’s throughput on comparable days.
Outlook
Sui’s continued volume performance amid a broader market decline suggests the network has developed a durable user base rather than purely speculative inflows.
The main risk is that a prolonged Bitcoin decline compresses risk appetite across all layer-1 assets. If the market stabilizes above $75,000 for Bitcoin, Sui’s volume is likely to remain elevated as the DeFi ecosystem continues to grow.
Investors will watch total value locked figures through late May 2026 as the next signal for whether Sui’s DeFi growth is sustaining or slowing.
