Last updated: 26 October 2026
SUI went from one of 2025’s standout layer 1 tokens to one of 2026’s hardest-hit. On 26 October 2026 it was trading at about $0.91, per CoinGecko, with a market cap near $3.7 billion (rank 30), 65% lower than a year earlier and 83% below its January 2025 high. This Sui price prediction explains what drove the decline, why unlocks matter so much for SUI’s maths, and what scenario ranges for the end of 2026, 2027 and 2030 look like once growing supply is built in.
Key takeaways
- SUI’s all-time high is $5.35, set on 4 January 2025; its 2026 low so far is about $0.65, reached on 19 August.
- Only about 4.12 billion of the 10 billion SUI circulate. Monthly unlocks of roughly 20–40 million tokens mean the per-token value of each $1 billion of market cap keeps shrinking.
- Spot SUI ETFs from Canary Capital (SUIS) and Grayscale (GSUI) launched on 18 February 2026, but they have not offset the broader altcoin sell-off.
- DeFi activity on Sui has contracted sharply: DefiLlama shows total value locked near $0.5 billion in late October 2026, down from more than $2 billion a year earlier.
- Our base case is $0.79–$1.10 for the end of 2026 and $0.76–$1.30 for the end of 2027, with all assumptions shown below.
How SUI got here
Sui’s mainnet went live in May 2023, built by Mysten Labs, a team of former Meta engineers. The token had a rough start, falling to its all-time low of about $0.36 in October 2023 as early unlocks hit a thin market. Through 2024 the picture changed: DeFi deposits, meme trading and gaming apps grew quickly, and SUI rallied more than tenfold from its mid-2024 lows to its $5.35 peak at the start of January 2025. At that moment roughly 3 billion SUI circulated, putting the network’s value at around $16 billion.
Then came the reversal. In May 2025 an attacker exploited Cetus, Sui’s largest decentralised exchange, for about $223 million. Validators froze roughly $162 million of the stolen funds and a governance vote approved returning them, which limited user losses but drew criticism that a small validator set could intervene in transactions. SUI held up through the middle of 2025, but after Bitcoin topped out in October 2025 near $126,000, SUI fell with the rest of the altcoin market.
2026 in numbers
| Point in 2026 | Approx. SUI price | What was happening |
|---|---|---|
| 1 January | $1.40 | Already down about half from October 2025 |
| 6 January | $1.91 | 2026 high during a brief new-year rally |
| 18 February | Around $1.00 | First US spot SUI ETFs begin trading |
| 19 August | $0.65 | 2026 low as altcoins bottom with Bitcoin’s summer slump |
| 30 September | $1.15 | Late-summer rebound ahead of Sui Basecamp in Singapore |
| 26 October | $0.91 | Market cap about $3.7 billion |
The product side kept moving despite the price. Mysten executives said gasless stablecoin transfers and upgrades to the DeepBook order book shipped during 2026, and Sui Basecamp, held on 7–8 October in Singapore, focused on payments, private transactions and AI agents.

Unlocks: the variable that shapes every SUI forecast
More than half of SUI’s maximum supply has not yet entered circulation. Allocations to early contributors, the Mysten Labs treasury, investors, the community reserve and stake subsidies continue to vest on monthly schedules that run toward the end of the decade. Recent monthly releases have been in the range of about 20–40 million SUI, with roughly 13 million scheduled for 1 November 2026 according to unlock trackers.
What this means in practice: if SUI’s market cap stays flat, its price drifts lower as the token count grows. Going from 4.1 billion to 4.6 billion tokens, a plausible end-2027 figure, cuts the value of each $1 billion of market cap from about $0.24 to about $0.22 per SUI. By 2030, with perhaps 6.5–7.5 billion circulating, it falls to roughly $0.13–$0.15. Unlock trackers have also found that SUI often weakened in the two weeks after past unlocks, though that is a loose historical pattern rather than a rule.
Bullish and bearish factors
Bullish
- Regulated access. Two spot ETFs, one of which stakes its holdings, plus 21Shares’ earlier 2x leveraged product, give US investors several routes into SUI.
- Payments push. Gasless stablecoin transfers and fast finality suit consumer payments if the apps follow.
- Staking demand. A large share of supply is staked, which reduces liquid float; our SUI staking guide explains delegation and rewards.
- Room to recover. SUI has historically rebounded hard when risk appetite returns, as in 2024.
Bearish
- Ongoing dilution from monthly unlocks for years to come.
- Shrinking DeFi base. TVL fell from more than $2 billion to about $0.5 billion over twelve months on DefiLlama’s figures, and stablecoins on Sui were only around $0.4 billion.
- Security and governance questions lingering from the Cetus incident and the validator freeze that followed it.
- Crowded competition from Solana, Aptos, Ethereum layer 2s and newer high-speed chains for the same developers and users. Our Aptos vs Sui comparison covers the closest rival.
Sui price prediction 2026 and 2027
Supply assumptions: about 4.17 billion SUI at the end of 2026 (so $1 billion ≈ $0.24 per SUI) and about 4.6 billion at the end of 2027 (so $1 billion ≈ $0.217). These are scenarios tied to those assumptions, not forecasts.
| Case | Assumptions | End-2026 | End-2027 |
|---|---|---|---|
| Bear | Altcoins stay in a downtrend; unlocked tokens meet thin demand; ETF holdings shrink; DeFi activity keeps contracting | $2.3B–$3B market cap $0.55–$0.72 |
$1.5B–$2.5B market cap $0.33–$0.54 |
| Base | Gradual recovery in crypto; staking and ETFs absorb most new supply; app usage stabilises | $3.3B–$4.6B market cap $0.79–$1.10 |
$3.5B–$6B market cap $0.76–$1.30 |
| Bull | A broad altcoin cycle in 2027; payments and stablecoin activity on Sui grow sharply; ETF inflows return | $5B–$7B market cap $1.20–$1.68 |
$10B–$15B market cap $2.17–$3.26 |
The 2027 bull band assumes Sui recovers to roughly two-thirds to all of its January 2025 peak valuation. Because there will be about 50% more tokens by then, even that outcome leaves the price well below $5.35. The bear case could be exceeded on the downside; the 2023 low was $0.36.
Sui price prediction 2030
For 2030 we assume around 7 billion SUI circulating, so $1 billion of market cap equals about $0.143 per token.
| 2030 case | Assumptions | Market cap | Implied SUI |
|---|---|---|---|
| Bear | Sui loses the layer 1 race to Solana and Ethereum rollups; usage stagnates while supply keeps growing | $1B–$3B | $0.14–$0.43 |
| Base | Sui settles in as a mid-sized smart contract platform with a steady app ecosystem | $5B–$10B | $0.71–$1.43 |
| Bull | Sui becomes a leading chain for consumer payments and on-chain finance, valued among the top layer 1s | $25B–$40B | $3.60–$5.70 |
A range spanning more than tenfold is the honest answer for a four-year horizon. Layer 1 rankings have reshuffled several times since 2020, and SUI’s exact supply in 2030 depends on vesting decisions that can still change, so long-range figures carry far more error than the near-term table.
Third-party forecasts
We did not find a bank or established research firm with a published SUI target in 2026. Algorithmic sites disagree wildly: DappRadar’s model, updated mid-2026, implied roughly flat-to-lower prices through 2030, while some prediction pages publish 2030 figures above $30. At 7 billion tokens, $30 SUI would imply a market cap of about $210 billion, larger than any smart contract platform except Ethereum today. Treat such numbers as model output or marketing, not analysis.
What to watch
- Unlock calendar: monthly release size and who receives it (community reserve versus insiders).
- ETF holdings of SUIS and GSUI, reported by the issuers.
- TVL and stablecoin supply on Sui via DefiLlama; a sustained recovery would support the base case.
- Staking ratio and validator count, visible on Sui explorers.
- Relative performance against Aptos and Solana; see our Solana price prediction for the sector leader’s outlook.
Buying SUI
SUI is listed on Coinbase, Binance, Kraken, OKX and other large exchanges, and can be withdrawn to Sui-native wallets such as Slush or Phantom. Make sure you select the Sui network when withdrawing. Our how to buy SUI guide covers the steps, while US investors can also use the SUIS or GSUI ETFs.

FAQ
Can SUI reach $10?
At 7 billion tokens in 2030, $10 SUI implies a market cap of about $70 billion, roughly 19 times today’s valuation and more than four times Sui’s January 2025 peak. That would require Sui to become one of the two or three most valuable smart contract networks. It is above our 2030 bull range, so we treat it as an outlier rather than a scenario.
Will SUI get back to $5?
At end-2027 supply of around 4.6 billion, $5 needs about $23 billion in market cap, above the roughly $16 billion SUI reached at its peak. By 2030, with around 7 billion tokens, $5 needs about $35 billion, which falls inside our 2030 bull band. So it is possible in a strong long-term scenario, but not in our 2026 or 2027 ranges.
What is a realistic Sui forecast for 2026?
Our base case for the end of 2026 is $0.79–$1.10, equal to a market cap of $3.3–$4.6 billion. That assumes roughly stable conditions over the last two months of the year. A deeper sell-off points to $0.55–$0.72; a sharp year-end rally to $1.20–$1.68.
Will Sui go up in 2027?
It depends on whether a broader altcoin recovery arrives and whether Sui can rebuild DeFi and payments activity faster than new tokens unlock. If both happen, the $2.17–$3.26 bull band becomes relevant. If not, rising supply can keep downward pressure on the price even when the network grows.
How does SUI compare with Aptos?
Both use the Move language and came out of Meta’s Diem project, and both face heavy unlock schedules. For the scenarios on Sui’s closest rival, read our Aptos price prediction. To convert any market cap assumption into a token price yourself, try our crypto calculators.
