Ostium: Funding, Investors & Team (Sep 2026)
Ostium delivers a decentralized trading platform that enables leveraged trading of real-world assets, including stocks, commodities, indices, foreign exchange, and cryptocurrencies, directly on-chain. Users maintain self-custody of their funds; trades, liquidity, and fees are publicly visible on a blockchain, removing reliance on traditional brokers. The platform offers up to 200× leverage and supports both long and short positions across a wide range of asset classes. Ostium uses real-time, low-latency price feeds via oracle systems to provide accurate and timely pricing. In addition, it recently introduced a points program that rewards user trading activity, referrals, and liquidity provision by converting on-platform engagement into a points ledger to track participation.
Ostium has raised $20.0M across 1 funding round on record, the most recent a Series A of $20.0M announced in Dec 2025.
That round is above the $6.3M median round size for Blockchain and Cryptocurrency companies tracked on FundedIQ over the last two years.

About FundedIQ's Ostium Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Ostium is left off this page rather than filled in.
