A wave of major token unlocks is approaching, with more than $1.8 billion worth of assets scheduled to enter circulation across several high-profile projects in December 2025.
The upcoming supply events span leading ecosystems such as Sui, LayerZero, Aptos, Arbitrum, and EigenLayer, creating one of the most concentrated monthly unlock periods of the year.
Sui and Aster Lead the December Unlock Calendar
The largest unlock of the month belongs to Sui (SUI), which will see $86.86 million worth of tokens released on December 1, representing roughly 1.51% of its circulating market cap. This is followed closely by Aster (ASTER)with another $86.84 million unlocking on December 17, accounting for 3.89% of its supply.
Both assets sit at the top of the monthly schedule not only because of the dollar value of their unlocks, but because their allocation ratios suggest notable near-term supply expansion, making them assets traders will monitor closely as the dates approach.
LayerZero, Pump.fun, and Aptos Add Mid-Month Pressure
Additional unlocks across LayerZero, Pump.fun, and Aptos bring significant liquidity shifts deeper into the month. LayerZero is set to unlock $33.7 million on December 20, which amounts to more than 10% of its market cap — one of the highest ratios among all assets listed.
Pump.fun follows with $31.2 million unlocking on December 14, alongside $25.2 million for Aptos on December 12. While the dollar amounts are smaller than Sui or Aster, the percentage-based impacts could introduce short-term volatility in each ecosystem.
EigenLayer, Arbitrum, Ethena, and STBL Round Out the List
EigenCloud will see $23.5 million unlocked on December 1, representing 8.3% of its supply, another substantial ratio within the monthly group. Arbitrum adds $20.63 million unlocking on December 16, while Ethena unlocks $27.66 million on December 2, and STBL releases $20.40 million on December 16.
Each of these assets brings its own community expectations and market context, but the consistent theme is that December’s unlocks are broadly distributed across both altcoin majors and emerging protocols.
Yooldo Esports Concludes the December Unlock Cycle
The final major unlock comes from Yooldo Esports (ESPORTS), which will see $19.44 million worth of tokens released on December 19, around 4.66% of its market cap. While not the largest on the list in raw dollar value, its allocation ratio makes it one of the more impactful upcoming supply events in relation to its circulating float.
A High-Impact Month for Supply Movements
With 10 major assets unlocking in the same 30-day window, December stands out as a month where supply-based catalysts could shape price action across multiple ecosystems. Traders and investors typically watch unlock schedules closely, as sudden increases in circulating supply can shift liquidity dynamics, alter sentiment, and create pockets of volatility, especially in markets already navigating uncertainty.
The scale and diversity of the upcoming unlocks make December 2025 one of the most important supply-side months of the year, and the market’s reaction to these releases may influence early-2026 price trajectories across several major blockchain networks.
