The Optimism Foundation has released its Year 5 budget outlook, projecting that approximately 343 million OP will enter circulation between May 2026 and April 2027, bringing the circulating supply to 2.504 billion OP, or 58.3% of the total supply.

The projected increase includes 200 million OP allocated to the Ecosystem Fund, 47.6 million OP for Early Core Contributors, 15.3 million OP for investors, and additional scheduled distributions under the original token allocation framework. The Foundation noted that no new token allocation has been requested.

Optimism also confirmed that no airdrops or Retro Funding distributions are currently planned for Year 5, while OP buybacks have surpassed 9 million tokens under the protocol's ongoing revenue-backed buyback program.

The Foundation emphasized that the projections are directional estimates and may change based on governance decisions and ecosystem performance.
