How to Check SUI Supply Before Buying on OKX: Circulating vs. Staked

OKX

08 October 2026

Before you buy SUI on OKX, you need to understand one key difference: SUI's "circulating supply" and its "freely tradable supply" are not the same number. The circulating supply shown on OKX or CoinMarketCap is around 4 billion tokens, but over 70% of that is locked in staking. The actual amount of SUI available for free trading in the market is much smaller than this figure.

First, Understand the Supply Structure: 10 Billion Total, About 41% Circulating

SUI has a maximum total supply of 10 billion tokens, fixed at genesis with no inflation. As of early September 2026, the circulating supply is approximately between 4.07 billion and 4.1 billion tokens, representing about 41% of the total. The remaining nearly 6 billion locked tokens will continue to unlock until 2030.

In terms of allocation, the community reserve accounts for 50%, early contributors 20%, investors 14%, Mysten Labs treasury 10%, and the community access program 6%. The community reserve is the largest portion, mainly used for validator staking subsidies and ecosystem development, released linearly over seven years.

Unlock Schedule: About 64 Million Tokens Monthly Until 2030

SUI's unlock is not a "one-time cliff" but rather a daily linear release schedule. The average monthly unlock volume for the remainder of 2026 is about 64 million SUI, equivalent to roughly 1%–1.7% of the circulating supply.

This means new SUI enters the market every month, creating continuous dilution pressure. Hindenrank's risk rating places SUI at grade C (risk score), explicitly listing "over 60% of supply still unlocking" as one of the main risks. A Chinese community analysis also directly pointed out that until the unlock is complete, the price will continue to reflect this "hidden tax."

Staking Ratio: 74% Locked, But Includes Foundation Tokens

This is the most easily misunderstood part. Multiple sources show SUI's staking ratio is between 72% and 77%. At first glance, this means only about 26%–28% of SUI is available for free trading, making supply extremely tight.

But there is a key detail here: a large portion of the staked SUI consists of locked tokens held by the foundation, not the result of active staking by free market users. The Sui Foundation controls over 50% of the total supply through the community reserve, and Mysten Labs holds another 10%. These locked tokens, if staked after unlocking, would inflate the "staking ratio" statistic, but they were never freely circulating in the market to begin with.

In other words: "74% staked" does not equal "74% of the free float is locked." What truly affects the price when you buy is the portion of tokens that have already been unlocked and are not held long-term by the foundation or early investors.

How to Check on OKX

OKX's SUI trading pairs (SUI/USDT, SUI/USDⓈ) were classified into Group 1 top-tier trading pairs in February 2026, which means relatively good liquidity, but specific fees are subject to what is shown on the page at the time of your operation.

You don't need to manually "check supply" on OKX. The key judgment factor to focus on is: how close your buying point is to the next major unlock or cliff event. SUI's unlock is linear, with no single "unlock day" that can precisely predict selling pressure, but you can monitor two indicators: the monthly change in circulating supply shown on Tokenomist or CoinGecko, and the release rhythm of staking subsidies from the community reserve.

An Easily Overlooked Risk: Network Upgrade Stability

Hindenrank's report also records a technical risk event: in May 2026, a bug in Sui's v1.72 upgrade caused the mainnet to pause block production three times within 48 hours, requiring emergency patching. This exposed stability risks in Sui's consensus layer (Mysticeti) during upgrade scenarios. For short-term traders, this is not the main source of daily volatility; but if you plan to hold long-term and participate in the ecosystem, this record is worth knowing.

Summary Judgment

Before buying SUI on OKX, check supply using two metrics:

Circulating supply (about 4.07 billion): This is the number shown on CoinMarketCap and OKX, but it includes tokens that have been unlocked but are staked.
Actual tradable supply: Circulating supply minus the staked portion. Since foundation-locked tokens account for a significant share of staking, the actual free float is smaller than "circulating supply × (1 - staking ratio)," but there is no precise public breakdown.

A more practical approach is to treat "about 64 million tokens unlocked per month" as your baseline expectation. As long as the price you buy at already reflects this continuous dilution, the unlock itself is not a "sudden negative." What truly requires vigilance is unlock concentration—if the unlock volume in a particular month suddenly jumps (for example, a one-time release from the community reserve), short-term selling pressure will increase significantly.
