Former U.S. Commodity Futures Trading Commission (CFTC) Chair Rostin Behnam told Crypto In America in an interview that with the explosive growth of prediction markets, Congress urgently needs to clarify the boundary between risk management and gambling, and related lawsuits may ultimately be brought before the U.S. Supreme Court. Behnam also noted that after the Clarity Act failed to advance in the Senate, the CFTC’s reliance on existing authority to regulate spot markets is akin to “patching with tape and paper clips,” adding that regulators urgently need to craft more durable rules.

Beating AI Insight News Brief: Anthropic has added an automatic tuning workflow to Claude Code’s official claude-api Skill. The build-eval module first generates test sets and scoring metrics from real conversations, bugs, or manual cases; hillclimb then enables Claude Code to iteratively modify system prompts, tool descriptions, models, and inference intensity. After each adjustment, tests are rerun: improvements are retained, while regressions are rolled back. To prevent Claude from overfitting exclusively to test cases, tuning is not performed on all samples at once. A subset of cases is used to identify issues and adjust configurations, while a separate batch is reserved to validate if modifications work on unseen problems. If the primary score improves but results on the reserved test set do not, the modification may be deemed overfitting and withdrawn. Anthropic demonstrated this workflow using 44 customer support tickets. Claude Code sequentially cleaned prompts, added business rules, tested different models, and reduced inference intensity, ultimately settling on a low-effort configuration for Sonnet 5. On 14 tickets not included in tuning, accuracy rose from 78.6% with the initial configuration to 90.5%, while costs fell to roughly one-fifth of their original level.

The Ethereum Foundation announced that the Glamsterdam network upgrade will activate on the Sepolia testnet at 21:53:36 Beijing Time on October 6, 2026 (epoch 353,024, slot 11,296,768). Activation timelines for the Hoodi testnet and Ethereum mainnet have not yet been finalized. The upgrade integrates the Amsterdam execution layer and Gloas consensus layer, with core improvements including: built-in proposer-builder separation (ePBS, EIP-7732), which formally incorporates block proposal and construction into the protocol; block-level access lists (BALs, EIP-7928), enabling parallel state reads and transaction verification; and adjusted gas pricing that more accurately reflects execution and state growth costs (EIP-8037, EIP-8038, etc.). Node operators must update their execution layer and consensus layer clients prior to activation. Corresponding client versions have been rolled out sequentially; detailed compatibility lists are available in the official announcement. Mainnet users and ETH holders do not need to perform any actions at this time.
