Ostium Labs
Private Round

Ostium Labs is the developer of Ostium, a self-custodial perpetual swaps protocol on Arbitrum that brings traditional markets (stocks, indices, commodities, FX, and RWAs) onchain for peer-to-peer trading. The platform has surpassed $25 billion in cumulative trading volume while emphasizing transparency, self-custody, and auditable smart contracts.
Ostium has not launched its native token yet but runs an active Points program that rewards traders and may lead to a future airdrop.
In December 2025, Ostium Labs closed a $20 million Series A round co-led by General Catalyst and Jump Crypto, with participation from Wintermute Ventures, Coinbase Ventures, and Crucible Capital. This funding, part of $24 million new capital, increased the company's total raised to $27.8 million.
