On May 27, 2026, Intercontinental Exchange CEO and founder Jeffrey Sprecher said at the Bernstein Strategic Decisions Conference that Hyperliquid is "bigger than Nasdaq," pointing to its scale despite a core team of 11 people. The piece contrasts that claim with token and equity valuations, then shifts to activity metrics such as roughly $180B in monthly volume and more than 70% share of the decentralized perpetuals market. It also flags regulatory uncertainty for U.S. and U.K. users and highlights upcoming dates including June 11 and the June 30, 2026 MiCA deadline.

OpenZeppelin co-founder and former CTO Manuel Aráoz said DeFi is unsafe and said he has privately advised friends and family to exit major "blue-chip" protocols. Industry figures including 0G Labs CEO Michael Heinrich and Cysic founder Leo Fan disputed the framing, citing about a 98% improvement in DeFi lending security since 2020 and daily loss rates near 0.001% on major lending protocols. They argued security is shifting toward continuous, machine-speed defenses and that regulators should prioritize operational security over a narrow focus on code.

Americanfortress has rolled out a beta of its compliance-oriented privacy infrastructure on Arbitrum, adding stealth-address tooling and name-based transfers aimed at institutional and high-volume DeFi use.

U.S. prosecutors say Google software engineer Michele Spagnuolo used confidential internal search rankings to trade Polymarket contracts and earned more than $1.2 million. The complaint alleges he put about $2.75 million at risk from Oct. 15, 2025, to Dec. 4, 2025, tied to Google's 2025 "Year in Search" results. The matter also includes a CFTC civil case seeking penalties and potential trading bans.

Brazil's Central Bank issued Normative Instruction No. 739 on Friday, adding a new condition for virtual asset service providers (VASPs) seeking authorization to operate in the country. Applicants must now submit an independent "reasonable assurance" audit prepared by a third-party entity registered with Brazil's securities regulator, alongside checks tied to AML/CTF controls and reporting readiness.

Kalshi said it sued Minnesota in federal court on May 28 to block SF4760, a law signed May 18 that would make operating or advertising prediction markets a felony when it takes effect on August 1, 2026. The company argues its event contracts are federally regulated derivatives under the Commodity Exchange Act and that the state law conflicts with CFTC authority and limits its ability to advertise a lawful product. The CFTC also brought its own case within 24 hours of the bill's signing and is seeking an injunction to pause enforcement.

Alephium said its TokenBridge on Ethereum was exploited, with roughly $815,000 drained after an attacker minted 13.76 million wrapped ALPH from forged transactions. The team urged liquidity providers to pull funds from ALPH pools on Uniswap and PancakeSwap and avoid swapping against those pools while the bridge remains shut down.

On May 30, 2026, Circle added Zama's cUSDC Ethereum smart contract to its blacklist, which stopped redemptions and locked about $12.6 million in pooled USDC. The action followed a U.S. federal court temporary restraining order tied to Newton AC/DC Fund LP's civil case against Overnight Finance founder Maxim Ermilov. Zama said it will try to separate the flagged deposit ahead of a June 1, 2026 hearing so unaffected users can regain access.
