IOST (IOST) Token Unlock & Vesting Schedule

As of October 25, 2026, 38.33 billion of the 90 billion IOST (42.59%) have been released. The schedule is ongoing, with no final release date. Over the next 12 months it releases 7.78 billion IOST (all estimated) from PoB/PoS network block and voting rewards, worth about $5.84 million at today's price (21.54% of the market cap). Today's release is an estimated 22.8 million IOST from PoB/PoS network block and voting rewards.

The chart shows gross modeled releases of every allocation: vesting unlocks, new issuance and reserve distributions, each allocation counted once. These have different meanings; a scheduled release is not evidence that tokens entered circulation or were sold. Review the coverage, sources and assumptions below.

Each color segment in the chart corresponds to a specific allocation group described in the Allocations section below. Underlying assumptions and data models used to reconstruct this schedule are explained in detail under Assumptions, while broader utility insights and token use cases are covered in Tokenomics & Utility.

Tokenomics & Utility

Supply and Emissions

Historically, IOST launched with an initial total supply of 21 billion tokens and used a reward schedule that included halving‑style block rewards. Early documentation in multiple languages also describes an annual compounding issuance band (1%–7%) that funded validator and ecosystem rewards. Over time, the economic model has been refined to reduce sell pressure and add burn mechanisms. (docs.iost.io)

The IOST 3.0 materials describe a strategic token evolution: longer‑term staking incentives, targeted airdrops for sustained participation (with a detailed allocation for the program), and calibrated reward distribution across node roles. The “Economic Model” and “Airdrop” proposals aim to balance network growth with value capture, including periodic burns tied to activity. (docs.iost.io)

Network Utility

The token’s primary functions include:

Paying for and accessing resources (iGas/iRam) by staking.
Securing the network through voting and node operation under PoB.
Powering smart contracts and DApps across payments, identity, and tokenization.
Supporting cross‑chain and Layer‑2 interactions in the IOST 3.0 stack.

These activities distribute rewards to block producers, partner nodes, and voters, with program details defined in the governance and tokenomics docs. (iost.zendesk.com)

Values at $0.00075 per IOST (October 25, 2026), today's price, not a forecast. Releases continue after September 2027. Estimated amounts are modeled from the schedule's rules rather than dated by a source; see the Assumptions below. Releases without dates are listed under Allocations.

Assumptions

IOST began with a reported 21 billion-token allocation and pays ongoing native-network block and voting rewards. Its newer plan budgets another 21.32 billion tokens for node rewards, airdrops, staking incentives, community programs, grants, a DAO and the team, but most payment dates and amounts are not verified. The chart can display the original creation and estimated changes between the supplied later supply observations; it cannot reliably split those changes among rewards, new-program releases and other supply adjustments. Conditional claims, grants and unanchored vesting plans remain listed but undated, and the historical figures do not support a complete reconciliation.
