US Sui ETFs attract five consecutive weeks of inflows on infrastructure upgrades

• US Sui ETFs recorded five consecutive weeks of inflows, accumulating approximately 14 million SUI tokens during the period
• Sui processed over 40 million transactions per second during a live stress test at Basecamp, exceeding its prior record by more than sixfold
• The network surpassed 5 billion total transactions and secured $500 million in capital commitments for its Bitcoin-finance project, Hashi

• 5 weeks Consecutive inflows into US-listed Sui ETFs, against Bitcoin and Ethereum fund headwinds
• 40M TPS Peak transaction throughput during stress test, versus 6.4 million prior record
• $500M Capital commitments secured for Hashi mainnet rollout, with 20+ participating institutions

Sui’s institutional appeal is consolidating around a narrow window of infrastructure maturity and AI-payment adoption. According to reporting from CryptoPotato, the layer-1 network has accumulated 14 million SUI through five consecutive weeks of ETF inflows, a divergence from the weakness plaguing Bitcoin and Ethereum spot funds. The timing aligns with a sequence of announcements spanning AI-agent payments, mobile stablecoin integration, Bitcoin finance, and cross-chain settlement infrastructure. The SuperTrend indicator on Sui’s 4-hour chart has also flashed a buy signal this week, the same technical pattern that preceded a 77 percent rally in prior instances.

Basecamp stress test demonstrates 40 million transactions per second, a sixfold improvement

Last week at Basecamp, Sui’s developer conference, the network executed a live stress test that processed over 40 million transactions per second using more than 10,000 programmable tunnels. This result surpassed the network’s prior record of approximately 6.4 million transactions per second and was achieved by simulating AI-agent activity with transactions settled natively on-chain.

The throughput milestone addresses one of the primary institutional concerns around layer-1 networks: whether they can handle real-world payment volume without external batching or rollup compression.

The stress test represents Sui’s first public demonstration of its ability to scale agent-driven payments at production-grade speeds. No other layer-1 has published comparable agent-payment throughput figures under identical network conditions, placing Sui as a technical reference point for the emerging AI-agent economy.

Alibaba Cloud partnership and Samsung integration enable stablecoin agent payments

Sui announced a collaboration with Alibaba Cloud to integrate cloud and artificial-intelligence inference services into its Agent Payments system, allowing autonomous agents to purchase computational resources using stablecoins with preset spending limits. Separately, Samsung Wallet is integrating Sui’s native USDC offering, targeting 82 million eligible Galaxy devices in the United States with gas-free stablecoin transfers. These two developments converge on a single institutional thesis: Sui is positioning itself as the settlement layer for AI-driven commerce between machines and cloud providers.

Circle’s Cross-Chain Transfer Protocol V2 has also launched on Sui, enabling native USDC to move between Sui and 29 other supported blockchains. The move signals Circle’s confidence in Sui as a hub for multi-chain payment flows and reduces friction for institutions moving dollar balances across networks.

Hashi secures $500 million in commitments for Bitcoin-finance mainnet launch this month

Sui’s Bitcoin-finance project, Hashi, is preparing a phased mainnet rollout in October 2026 and has raised over $500 million in capital commitments from more than 20 participating institutions, with Anchorage Digital serving as the launch partner.

The $500 million figure signals institutional demand for Bitcoin-backed lending and yield products on Sui’s blockchain rather than on purpose-built protocols like Stacks or Merlin. Hashi’s roadmap aims to unlock liquidity in Bitcoin held in long-term reserve positions, a use case that appeals to institutions sitting on large Bitcoin positions and seeking yield without liquidation risk.

In tandem with the capital-raise milestone, Sui surpassed 5 billion total transactions, standing at approximately 5.02 billion, positioning the network ahead of many major layer-1 competitors by cumulative on-chain activity. The milestone was reached despite historical outages, including three major incidents totaling more than 15 hours in May 2026 and a consensus bug in January that caused five hours and 52 minutes of downtime.

The CCS read. We see Sui’s ETF inflows as institutional positioning ahead of October agent-payment and Bitcoin-finance production launches, not as conviction in the token itself. If Hashi’s mainnet or Samsung’s USDC integration fail to drive stablecoin settlement volume by year-end, inflows will reverse. The real test is whether enterprises and AI platforms actually choose Sui over Solana for payments, not whether the throughput benchmark is impressive.

Watch for Hashi’s phased mainnet launch later this month and the initial transaction volume on Sui’s Bitcoin-finance system; the sustainability of ETF inflows depends entirely on whether the $500 million in committed capital translates into measurable daily settlement activity. If Hashi’s October release generates less than $10 million in daily Bitcoin-backed lending volume, institutional appetite may cool by November.
