Prediction markets have expanded quickly as politically connected firms gained faster regulatory access, intensifying scrutiny around fairness and consumer protection. Monthly prediction-market volume rose from below $100 million in early 2024 to more than $13 billion by late 2025. Inside the CFTC, reported suspensions and staff departures added to concerns over how reviews and enforcement are being handled.

Babylon Labs has submitted a temperature-check proposal to integrate with Aave V4, aiming to let users lock native BTC on Bitcoin and borrow assets via Aave without wrapped BTC, bridges, or custodians. The design uses Taproot-based vault scripts and introduces a non-transferable accounting asset, vaultBTC, to represent BTC locked in Babylon vaults as collateral within approved Aave contracts. Aave founder Stani Kulechov endorsed the idea on X and said Babylon has more than $4bn in BTC staked that could eventually be used as collateral.

Inertia said an exploit drained about $152,000 after attackers inflated roETH collateral pricing and borrowed against it across five lending markets. The protocol's post-mortem, published on 25 May, said the incident impacted USDC, INIT, sINIT, TIA, and roTIA during an attack window of roughly 1 hour and 13 minutes.

Chainlink has deployed its Cross-Chain Interoperability Protocol (CCIP) to Neo X on MainNet, as noted in a Chainlink blockchain expansion update published on May 22. The integration adds cross-chain messaging now and lays groundwork for token transfers, with Chainlink documentation showing an active Neo X–Ethereum lane but no tokens configured for transfer yet.

A U.S. Senate CLARITY Act draft would extend a ban on paying APY on idle stablecoin balances to exchanges, brokers, and other custodial intermediaries, while allowing yield tied to transactional activity. STBL Chief Compliance Officer Joe Vollono says the pressure may push returns toward “Yield-as-a-Service,” where AI agents execute compliant strategies through DeFi instead of passive rewards. A separate White House Council of Economic Advisers model estimates the prohibition could add roughly $2.1 billion in U.S. bank lending and carry a net welfare cost of $800 million.

SlowMist issued an emergency alert labeled SM-2026-352284, saying it has detected an active cross-registry supply-chain campaign aimed at Web3 and AI builders. The firm said attackers published more than 34 malicious packages and 384 related versions across npm, PyPI and Crates.io to steal crypto wallets and developer credentials. SlowMist advised teams to remove the packages, isolate affected machines and follow a three-step remediation plan including AI config checks, credential rotation and a full rebuild.

Ethereum co-founder Vitalik Buterin says many smart contract wallets and privacy tools still rely on third-party relays to get transactions included onchain, creating potential censorship and reliability risks. He points to FOCIL and EIP-8141, slated for the Hegota upgrade in late 2026, as a path to route transactions through the public mempool with a randomized validator inclusion model and a one-to-two slot inclusion target.

On May 20, 2026, U.S. Representative Summer Lee and Senator Bernie Sanders introduced the Abolish Super PACs Act in the House and Senate, seeking to limit individual super PAC contributions to $5,000. The proposal targets independent-expenditure groups as crypto-linked super PACs gain visibility in policy fights over stablecoins and market structure, and as overall election spending by outside groups continues to expand.
