Ostium Labs
Strategic Round

Ostium Labs is a self-custodial perpetual swaps protocol built on Arbitrum that enables peer-to-peer onchain trading of traditional markets including stocks, indices, FX, commodities, and real-world assets. The platform has processed over $25 billion in cumulative trading volume with sub-second price feeds and fully auditable smart contracts.

Ostium has not yet launched its native token, although the project operates an active points program that may lead to future airdrop rewards.

Ostium Labs closed a previously unannounced $4 million strategic round in late 2025. This round formed part of $24 million in new capital (including the subsequent $20 million Series A) and brought the project’s total funding to $27.8 million.
