The upward trend among financial institutions faces a significant drag from the investment banking sector. Shares of Goldman Sachs Group and Morgan Stanley slipped following reports suggesting that OpenAI could push its highly anticipated multibillion-dollar initial public offering as far as 2027. This potential delay removes a major catalyst for market excitement, dampening enthusiasm for financial firms heavily invested in the IPO pipeline.

Simultaneously, the prediction market Polymarket is under mounting political pressure. Senators John Curtis, a Republican from Utah, and Adam Schiff, a Democrat from California, are demanding a federal investigation into the platform. This push follows reports regarding the company's social-media promotion of fabricated wagers, highlighting concerns over deceptive marketing practices that have now drawn the attention of Washington.
