SUI, the native token of the Sui Network — a layer-1 blockchain — climbed approximately 54% over a 30-day stretch ending in early October 2026,pacing both Bitcoin and Ether, which also advanced during the broader market recovery but at a slower pace.

The rally did not happen in a vacuum. It landed alongside a run of ecosystem news, including a new institutional yield product from Bitwise and a record throughput figure unveiled at Sui's own developer conference.

The Numbers Behind the Move

Over the past four weeks, the dollar value of assets deposited in Sui's decentralized finance applications grew 15.5%. That metric is known as total value locked, or TVL, and it is one of the standard yardsticks for gauging how much activity sits on a blockchain's DeFi applications.

The four-week gain came even after a 5.2% decline over the most recent week. The pullback lined up with SUI's price cooling off, which matters because a chunk of that locked value is denominated in the token itself.

Sui's DeFi TVL peaked at roughly $1.21 billion on September 22, 2026. Contributions from NAVI Protocol, a lending platform on the network, helped push the figure to that high.

On the trading side, SUI moved within a range of $1.15 to $1.27 during the period. By early October, the token was changing hands at approximately $1.12 to $1.15, toward the lower end of that range.

At those levels, SUI's market capitalization sat around $4.6 billion. Roughly 4.1 billion tokens were in circulation, out of a maximum supply of 10 billion, meaning about 41% of the eventual supply was on the market.

What Fueled the Rally

Several ecosystem developments arrived in quick succession.

First, asset manager Bitwise launched its PPLUS Premium+ RWA Vault on Sui. RWA stands for real-world assets, the industry term for bringing traditional financial instruments like credit or treasuries onto a blockchain. The vault targets a net yield of more than 10% and is aimed at institutional assets.

Second, Sui posted a record of 40.6 million transactions per second during a stress test at its Basecamp conference, held October 7-8. The test was conducted off-chain — a caveat that deserves attention, since an off-chain stress test shows what the underlying technology can handle under controlled conditions, which is different from sustained real-world usage on the live network.

Third, Samsung announced USDC support for its Galaxy devices, with Sui capabilities integrated into the setup. USDC is a dollar-pegged stablecoin, and putting it in front of Galaxy users potentially exposes millions of people to Sui-powered features. For a network whose ecosystem growth has so far been tracked mainly through DeFi metrics, consumer distribution is a different channel — and one whose impact will show up, or not, in actual usage rather than announcements.

The Long Road Back

SUI hit an all-time high of around $5.35 in January 2025. Even after the four-week rally, the token's early October 2026 price left it roughly 78% below that peak.

Put differently, a holder who bought at the top would need the token to roughly quadruple from current levels just to break even.

Supply and Ecosystem Considerations

With only about 41% of the maximum supply circulating, the remaining tokens represent future supply that could enter the market over time. Investors evaluating SUI's market capitalization should keep the fully diluted picture in view. At early-October prices of roughly $1.12 to $1.15, valuing the full 10 billion token supply would put the fully diluted figure near $11.2 billion to $11.5 billion — more than double the current market capitalization.

The recent 5.2% weekly TVL drop is another reminder of how tightly Sui's DeFi metrics track its token: when the price falls, the ecosystem's headline numbers shrink along with it. That coupling, alongside the supply overhang, leaves a short list of concrete markers to watch from here: how much of the remaining 59% of supply actually reaches the market, whether the Samsung-USDC integration converts into measurable usage, and whether the performance shown in controlled tests appears on the live network.
