Data: Tokens Like SUI, BIO, and OP Set for Major Unlocks This Week
On May 25, 2025, crypto analytics platform Token Unlocks released its latest unlock forecast, showing that several popular tokens — including Sui (SUI), Bio Protocol (BIO), and Optimism (OP) — are scheduled for major unlock events in the upcoming week, with a total market value exceeding $500 million. These unlocks have sparked widespread community discussion and drawn intense attention from investors regarding the short-term price movements of the involved tokens.
As we all know, token unlocks typically mean that tokens previously locked by the project team, investors, or associated addresses will enter the circulating supply. According to market supply-demand dynamics, if the unlock scale is significant and there isn’t enough buy-side support, it can easily lead to short-term sell pressure and cause price declines. However, not all unlocks bring “bearish” effects — it also depends on unlock proportion, market sentiment, current price range, project transparency, and pre-unlock expectations.
In this round of scheduled unlocks, SUI and BIO top the charts in terms of unlock value — $154 million and $28 million respectively — with BIO’s unlock accounting for 20.22% of its circulating supply, making it a primary focus for investors. In addition, other projects like Optimism, Kamino, ZetaChain, Renzo, and dYdX will also release tokens at various scales, potentially creating local turbulence in their respective ecosystems and sectors.
It’s worth noting that just ahead of SUI’s unlock, its ecosystem DEX Cetus Protocol experienced a security breach, raising concerns over the security of the Sui ecosystem and confidence in its capital. At the same time, long-standing projects like Optimism and dYdX are also facing mounting regulatory pressure and increased competition — altogether forming a complex market backdrop leading into the unlocks.
Below is a token-by-token breakdown of this week’s major unlocks, their basic profiles, unlock scale, potential risks, and possible market responses.
Sui (SUI)
Unlock Time: June 1, 2025, 05:00 (UTC)
Unlock Amount: ~44 million tokens, ~1.32% of current circulating supply
Unlock Value: ~$154 million
SUI is the largest unlock of the week in dollar terms. Developed primarily by Mysten Labs, SUI is positioned as a next-generation high-performance Layer 1 blockchain, built with the Move language and optimized for scalability and concurrency. This unlock involves multiple addresses, including the foundation, ecosystem incentives, early investors, and team allocations — part of a scheduled large-scale unlock program.
It’s worth noting that just days ago, Cetus Protocol, one of the most active DEXs in the SUI ecosystem, suffered a major contract vulnerability exploit, resulting in $223 million stolen, with $60 million escaping recovery despite emergency freezes. The incident raised serious concerns over Sui’s ecosystem security. Some users fear that vulnerabilities may not be fully addressed yet, potentially amplifying market sensitivity around the SUI unlock.
Although Sui’s growth potential remains strong, we still cannot rule out the possibility of sell pressure triggered by this unlock.
Bio Protocol (BIO)
Unlock Time: May 28, 2025, 05:00 (UTC)
Unlock Amount: ~339 million tokens, ~20.22% of circulating supply
Unlock Value: ~$28 million
BIO’s unlock this round accounts for over 20% of circulating supply, making it the most alarming among all listed projects. The unlocked tokens include early investor and private round releases, as well as part of the team’s scheduled unlocks. In the current market, which hasn’t fully recovered, and without strong bullish news or tech releases, BIO may face liquidity overflow risks. If core holders choose to realize profits, the price may face significant downward pressure.
Optimism (OP)
Unlock Time: May 31, 2025, 05:00 (UTC)
Unlock Amount: ~31.34 million tokens, ~1.83% of circulating supply
Unlock Value: ~$22.7 million
While OP’s unlock scale isn’t extreme, as one of the most recognized Ethereum Layer 2 solutions, every OP unlock attracts broad market attention. The current release mainly comes from the foundation and community incentive allocations, contributing to some supply-side pressure.
Additionally, increasing regulatory scrutiny on Layer 2s in the U.S. poses a non-negligible threat to OP and similar projects. Investors should be alert to regulatory news and large on-chain wallet activity, which could influence OP’s price action.
Kamino (KMNO)
Unlock Time: May 30, 2025, 17:00 (UTC)
Unlock Amount: ~229 million tokens, ~14.97% of circulating supply
Unlock Value: ~$15.1 million
Kamino is an automated yield strategy platform within the Solana ecosystem, combining liquidity mining, auto-rebalancing, and yield aggregation features, with solid TVL growth. However, KMNO — as its native token — has experienced high volatility since launch.
This nearly 15% unlock involves team and early community contributor allocations. Without clear lock-up or distribution plans, the market could interpret it as a premature cash-out signal. Given the frequent liquidity attacks and gas fee volatility in Solana’s ecosystem, KMNO’s unlock may heighten user hesitation.
Mid-term, if Kamino attracts more stablecoin and on-chain asset participation and builds a more robust yield model, the market may gradually accept its token release pace.
ZetaChain (ZETA)
Unlock Time: June 1, 2025, 05:00 (UTC)
Unlock Amount: ~44.26 million tokens, ~5.34% of circulating supply
Unlock Value: ~$10.9 million
This unlock involves ecosystem development funds and some advisor incentives. Though 5.34% isn’t extreme, in a volatile broader market, it’s enough to trigger short-term price swings.
If the team aligns the unlock with ecosystem updates — such as launching DApps, cross-chain DEX integrations, or auto-bridging support in major wallets — it could help improve ZETA’s market reception and raise its valuation ceiling.
Renzo (REZ)
Unlock Time: May 30, 2025, 16:00 (UTC)
Unlock Amount: ~423 million tokens, ~16.10% of circulating supply
Unlock Value: ~$5.7 million
REZ’s unlock involves massive token volume, albeit at a low unit price. The project focuses on LRT (Liquid Restaking Tokens) and the liquid staking market — positioning itself as an emerging player in the EigenLayer ecosystem.
This unlock includes many seed investors and early strategy node rewards. The market worries these low-cost holdings could be dumped, especially given the absence of a stable revenue model.
If the team can simultaneously launch LRT toolkits and disclose TVL growth metrics, it might ease some sell pressure. However, with REZ’s high current valuation base, this unlock phase will likely face a short-term stress test.
DYdX (DYDX)
Unlock Time: June 1, 2025, 05:00 (UTC)
Unlock Amount: ~8.33 million tokens, ~1.07% of circulating supply
Unlock Value: ~$5 million
As a veteran decentralized perpetuals platform, dYdX’s unlock impact is relatively small. This round includes early ecosystem subsidies and team distributions. The amount is moderate, and market volatility is expected to be limited.
Market Impact Analysis
This week’s large-scale token unlock events could bring the following effects:
Short-Term Price Volatility
Large unlocks may result in short-term price swings, especially for high-ratio unlocks like BIO and REZ. Investors may sell in advance out of fear, further amplifying volatility.Market Sentiment Shifts
Unlock events can influence overall investor sentiment. If perceived negatively, they could cause broader caution across the market, affecting unrelated tokens as well.
Investor Advice
Faced with these upcoming unlocks, investors should:
Track unlock schedules closely: Know when and how much is unlocking — be prepared.
Assess project fundamentals: Analyze actual use cases, team background, and market outlook to evaluate unlock impact.
Set risk management strategies: Define stop-loss and take-profit points — control risk.
Monitor sentiment: Follow community discussion and news to gauge emotional tone and adjust strategy accordingly.
Conclusion
In summary, this week’s unlock events are concentrated and substantial, involving major projects across multiple sectors. With the overall market still in correction mode, these unlocks could become local disturbances, or even trigger short-term trend reversals.
Short-term traders should adopt clear stop-loss and risk control strategies, while mid- to long-term investors should focus on fundamentals and long-term roadmap, and rationally assess whether the unlock represents real sell pressure — or just a temporary psychological shake-up.
