Basis Markets
Summary
Basis Markets was a UK-based project that raised approximately $28 million from retail investors in late 2021 through NFT membership sales and a BASIS token offering, marketing itself as a decentralized algorithmic hedge fund offering delta-neutral arbitrage returns. The UK Serious Fraud Office (SFO) opened a formal investigation and, on 20 November 2025, arrested two men on suspicion of fraud and money laundering in what the SFO described as its first major cryptocurrency case. The project shut down in June 2022 citing proposed US regulatory changes, and on-chain analysis by independent researchers alleged that investor funds were routed directly to founders' personal wallets rather than a project treasury.
