A significant wave of token unlocks is anticipated in December 2025, with over $1.8 billion worth of assets poised to enter circulation across several prominent projects. This period represents one of the most concentrated monthly unlock events of the year, impacting leading ecosystems such as Sui, LayerZero, Aptos, Arbitrum, and EigenLayer.
Sui and Aster Lead the December Unlock Calendar
The largest unlock event in December will be for Sui (SUI), with $86.86 million in tokens scheduled for release on December 1. This unlock represents approximately 1.51% of its circulating market cap. Following closely is Aster (ASTER), which will see $86.84 million in tokens unlocked on December 17, accounting for 3.89% of its total supply. These two assets are at the forefront of the monthly schedule, not only due to their substantial dollar values but also because their allocation ratios indicate significant near-term supply expansion, making them key assets for traders to monitor as these dates approach.
LayerZero, Pump.fun, and Aptos Contribute to Mid-Month Pressure
Additional token unlocks from LayerZero, Pump.fun, and Aptos are expected to introduce significant liquidity shifts into the market later in the month. LayerZero is slated to unlock $33.7 million on December 20, a figure that constitutes over 10% of its market cap, marking one of the highest unlock ratios among all listed assets. Pump.fun will follow with $31.2 million unlocking on December 14, alongside Aptos, which will release $25.2 million on December 12. Although the dollar amounts for these projects are lower than those of Sui or Aster, their percentage-based impacts could potentially introduce short-term volatility within each respective ecosystem.
EigenLayer, Arbitrum, Ethena, and STBL Complete the List
EigenCloud is set to unlock $23.5 million on December 1, representing a substantial 8.3% of its supply, another significant ratio within the month's unlock group. Arbitrum will add $20.63 million to circulation on December 16, while Ethena plans to unlock $27.66 million on December 2, and STBL will release $20.40 million on December 16. Each of these assets carries its own set of community expectations and market contexts. However, the overarching theme is that the December unlocks are broadly distributed across both major altcoins and emerging protocols.
Yooldo Esports Concludes the December Unlock Cycle
The final notable unlock event for December comes from Yooldo Esports (ESPORTS), which will see $19.44 million worth of tokens released on December 19. This amount represents approximately 4.66% of its market cap. While not the largest unlock in terms of raw dollar value, its allocation ratio makes it one of the more impactful upcoming supply events relative to its circulating float.
A High-Impact Month for Supply Movements
With ten major assets scheduled to unlock within the same 30-day window, December is poised to be a month where supply-side catalysts could significantly influence price action across numerous ecosystems. Traders and investors typically pay close attention to unlock schedules, as sudden increases in circulating supply can alter liquidity dynamics, affect market sentiment, and create pockets of volatility, particularly in markets already navigating periods of uncertainty. The scale and diversity of these upcoming unlocks position December 2025 as a critical month for supply-side events, and the market's reaction to these releases may have a notable influence on price trajectories for several major blockchain networks in early 2026.
