September is shaping up to be a big month for crypto investors as blockchain projects get ready to release around $4.5 billion worth of locked tokens. This huge amount of new supply hitting the market could shake things up across different cryptocurrency networks.

Most of this money will come in two ways—about $1.17 billion through sudden large releases called cliff unlocks and $3.36 billion through steady smaller releases over time. The cliff releases usually cause more price swings because they dump lots of tokens at once, while the gradual releases are easier for markets to handle.
Sui is planning the biggest release, with more than $153 million in tokens becoming available. What’s interesting is they’ve only released about 35% of their total supply so far, so there’s still plenty locked up. Fasttoken comes next with $90 million, but they’ve already released most of their tokens, so this won’t be as big a deal.
Aptos and Arbitrum are also releasing significant amounts—around $50 million and $48 million each. Smaller releases include Starknet with $16.85 million and Sei adding $16.49 million.
The good news? Experts say investors aren’t panicking about unlocks like they used to, focusing more on whether projects are actually useful rather than just worrying about token dumps.
Conclusion
While September’s $4.5 billion unlock seems massive, the crypto market’s growing maturity suggests these releases may be absorbed more smoothly than previous cycles.
