Markets entered Sept. 15 with regulation driving the tape: Bitcoin slipped as odds on the Clarity Act shifted, even as reports pointed to potential upside for some majors if the bill advances. Separately, Solana saw another network upgrade and a wave of treasury-related capital moves.
Clarity Act vote keeps regulation in focus
Bitcoin traded lower in early U.S. hours as investors watched the Senate’s procedural vote on the Clarity Act, with reports saying the bill’s odds had faded on prediction markets. Coverage also noted that ether, solana and XRP could benefit if the measure progresses, while Democrats were said to be pushing back with a counterproposal and banking and tribal groups were raising objections. A House tax package published ahead of a hearing would address de minimis transactions, staking and other crypto tax issues, though it would leave mining and staking-reward deferral unchanged.

Solana gets a larger transaction limit
Solana raised its transaction size limit to 4,096 bytes, more than tripling the prior cap. The upgrade is intended to give developers more room for multi-signature flows, privacy proofs and other more complex transactions.

Treasury firms and balance-sheet buys continue
DeFi Development Corp added 55,491 SOL and launched a $300 million at-the-market program tied to its preferred stock, extending a recent run of capital-markets activity. On the Bitcoin side, Strive disclosed a $36.6 million purchase that brought its holdings to 25,000 BTC, while Stack BTC said it plans to acquire a gold dealer to help fund further bitcoin buying.
Security, exchange and enforcement updates
Security firms traced a $7.8 million wallet drain to a helper contract the owner had authorized. In exchange news, Hong Kong-based CoinEx said it will cease operations after nine years, citing security, compliance and market-contraction pressures, and keeping withdrawals open until Dec. 22. Separately, U.S. prosecutors sought $61 million in a civil forfeiture case tied to alleged crypto-laundered Iranian oil proceeds.
