Approximately $4.7 billion in crypto tokens are scheduled to unlock during September 2026, comprising $1.2 billion in cliff unlocks and $3.5 billion in linear vesting releases. The wave arrives as Bitcoin trades near $80,861 and the broader market contends with Federal Reserve rate-hike expectations and geopolitical risk from renewed Iran tensions.
The first week alone accounts for roughly $1.5 billion in new supply, led by Hyperliquid's $797 million cliff unlock on September 6. Rain's linear vesting schedule contributes the single largest dollar-value stream at $568.96 million across the late-August-to-September window, equivalent to 6.35% of circulating supply. Solana ecosystem tokens add another approximately $100 million in supply events, headlined by $TRUMP's $60.25 million release.
Research by market maker Keyrock, analyzing over 16,000 historical unlock events, shows 90% of unlocks generate negative price pressure — with declines typically beginning 30 days before the event date. However, actual market impact depends on claim rates, holder behavior, and protocol-level buyback mechanisms. Hyperliquid's historical claim rate of 0.79% against total contract-level unlocks illustrates the gap between scheduled supply and realized selling.
The full September 2026 schedule spans more than a dozen major tokens. The aggregate $4.7 billion figure breaks down as follows:
| Date | Token | Unlock Amount | Est. Value | Type | % of Circ. Supply | |------|-------|--------------|-----------|------|--------------------| | Sep 1 | SUI | 13.53M tokens | ~$9.73M | Cliff | Split: 7.47M Early Contributors, 4M Community Reserve, 2.07M Mysten Labs | | Sep 2 | ENA | 40.63M tokens | ~$6.05M | Cliff | 0.46% of released supply | | Sep 6 | HYPE | 9.92M tokens | ~$797M | Cliff | 2.37% of released supply | | Sep 12 | APT | 14.36M tokens | ~$8.0M | Cliff | 0.7% of total supply | | Sep 15 | SEI | TBD | ~1.5% of market cap | Cliff | — | | Sep 20 | KAITO | TBD | TBD | Cliff | — | | Sep 23 | SOON | ~20.24M tokens | ~3.5% of market cap | Cliff | — | | Sep 30 | KMNO | 229.17M tokens | ~$5.51M | Cliff | 4.21% of circulating supply | | Ongoing | RAIN | Daily linear | ~$568.96M (30-day) | Linear | 6.35% of circulating supply | | Ongoing | TRUMP | 28.27M tokens | ~$60.25M | Linear | 10.35% of circulating supply | | Ongoing | PUMP | 6.875B tokens | ~$28.8M | Linear | 1.73% of circulating supply |
HYPE dominates by dollar value. By percentage of circulating supply, $TRUMP (10.35%) and RAIN (6.35%) present the steepest dilution ratios.
Hyperliquid (HYPE) — September 6 — $797 million. The single largest cliff unlock of the month allocates 9.92 million tokens to Core Contributors. At HYPE's current price near $86.75 — within 1.5% of its all-time high of $88.04 set September 3 — the theoretical market impact is substantial. The token rose to prominence as Hyperliquid processed more daily notional perpetual futures volume than GMX, dYdX, and Drift combined during multiple sessions in mid-2026.
Sui (SUI) — September 1 — $9.73 million. The 13.53 million SUI unlock splits three ways: 7.47 million to Early Contributors, 4 million to Community Reserve, and 2.07 million to Mysten Labs Treasury. At under $10 million, the dollar value is modest relative to SUI's market capitalization.
Ethena (ENA) — September 2 — $6.05 million. The 40.63 million ENA release represents 0.46% of the released supply. At this scale, the unlock is unlikely to generate material selling pressure absent broader market weakness.
Aptos (APT) — September 12 — $8.0 million. The 14.36 million APT token unlock represents 0.7% of total supply.
Solana Ecosystem — ~$100 million aggregate. According to Crypto Briefing and SolanaFloor, the Solana ecosystem faces nearly $100 million in token unlocks across September. The $TRUMP token's $60.25 million linear release represents the largest by dollar value, covering 10.35% of circulating supply and 2.71% of total supply. Pump.fun follows with 6.875 billion $PUMP tokens worth approximately $28.8 million (1.73% of circulating supply). Kamino's $KMNO unlock on September 30 adds $5.51 million (4.21% of circulating supply).
The $TRUMP release carries a distinct risk profile. At 10.35% of circulating supply, the dilution ratio exceeds that of most competing tokens this month. The linear vesting structure spreads supply entry across the month rather than concentrating it on a single date, which tends to moderate acute price shocks but sustains persistent background selling.
Rain's linear vesting schedule constitutes the single largest dollar-value stream across the September unlock calendar. At approximately $568.96 million over the late-August-to-September window, it accounts for over 44% of the August-September unlock total by one measure. The release represents 6.35% of RAIN's circulating supply.
Because the tokens enter the market on a continuous daily schedule rather than through a cliff event, the sell pressure distributes across every trading session. This structure tends to suppress sustained rallies rather than cause one-day crashes. For market makers providing liquidity in RAIN pairs, the ongoing supply injection compresses bid-ask spreads and increases inventory risk.
Market maker Keyrock's analysis of over 16,000 historical token unlock events provides the most comprehensive empirical dataset available on supply-event impacts. The key findings:
The data indicates that over $600 million in previously locked tokens enter circulation weekly across the industry. September 2026's $4.7 billion figure implies roughly four times the normal monthly run rate, concentrated in a handful of protocols.
Hyperliquid presents a case study in why scheduled unlock values can overstate realized sell pressure. According to Tokenomist data:
For the August 29 unlock — a $1.2 billion event involving 14.18 million tokens — HYPE fell approximately 3.5% from its all-time high of $86.71 to $82 in the days surrounding the event. By September 3, the token had recovered to a new record of $88.04.
Two structural factors support this resilience. First, the protocol directs 97% to 99% of protocol revenue toward automatic HYPE buybacks on open markets. Second, the Assistance Fund had accumulated approximately 45.7 million HYPE tokens as of July 2026, providing a standing bid.
The Hyper Foundation announced approximately 330,000 HYPE for distribution in April 2026 — against a theoretical unlock of 9.92 million, a 30x discrepancy. This pattern suggests September 6's $797 million headline figure substantially overstates the likely circulating supply increase.
The September unlocks arrive during a period of compounding macro uncertainty. Bitcoin fell 1.67% to $77,593 on September 1 before recovering to $80,861 by September 3. Ethereum dropped 2.32% to $2,419 before rebounding to $2,501. Polymarket traders assign only 32% odds to Bitcoin reaching $100,000 in 2026, while giving 72% odds to a revisit of $75,000.
Contributing factors include mounting expectations of a Federal Reserve rate increase, the August jobs report due September 5, and renewed Iran-related geopolitical tensions that rattled markets on September 2. Risk-off sentiment persists across crypto asset classes.
For tokens facing large unlocks, this backdrop compounds the supply-side challenge. Thin liquidity during risk-off episodes amplifies the price impact of any selling. Conversely, for protocols with strong buyback mechanisms (such as Hyperliquid) or low historical claim rates, the macro environment may matter more than the unlock schedule.
September 2026's $4.7 billion unlock schedule represents one of the heaviest supply months on record for the crypto market. The concentration of value in a handful of tokens — HYPE, RAIN, and the Solana ecosystem — creates pockets of acute dilution risk rather than evenly distributed pressure.
The data challenges simplistic narratives in both directions. The headline $797 million for HYPE overstates likely selling by an order of magnitude given sub-1% historical claim rates. Conversely, Rain's 6.35% circulating supply dilution via continuous linear vesting creates persistent headwinds that cannot be dismissed by pointing to low one-time claim rates.
For market participants, the Keyrock dataset offers a framework: track not just the unlock date but the 30-day anticipation window, the recipient category (team vs. investor vs. ecosystem), and the unlock-to-volume ratio. When unlocks exceed 2.4x daily trading volume, order book dynamics shift meaningfully.
The next material data point arrives September 5, when the August employment report may set the macro tone for the month. If risk appetite contracts further, the $1.5 billion in first-week unlocks will test buyer depth at a particularly unfavorable moment.
