On September 15, Coinbase Global, Inc. fell 5.6% in regular trading, trading at $181.5/share, with turnover of $173 million, as the crypto sector came under broad pressure ahead of a pivotal U.S. Senate procedural vote on the CLARITY Act.

The U.S. Senate scheduled a key procedural vote on the Digital Asset Market Clarity Act for the afternoon of September 15, requiring at least 60 votes to advance. With Republicans holding only 53 seats, passage depends on securing Democratic support, which remains highly uncertain. Prediction platform Polymarket showed the probability of the bill passing this year had retreated from above 30% to roughly 18%-29%, reflecting fading market optimism. Multiple Democratic senators continued to push for further amendments, particularly on ethics provisions related to presidential crypto interests.

Simultaneously, Bitcoin retreated from a high of $79,586 and broke below $78,000, dragging the broader crypto sector lower. Ark Invest sold approximately $7 million in Coinbase shares alongside reductions in other crypto-related holdings. Additionally, Coinbase directors Marc Andreessen and Frederick Wilson recently disclosed stock sales totaling over $4.2 million, while options market activity featured bearish large-block trades betting on limited upside.
