Key Takeaways

The S&P 500 added 0.3% on Wednesday, Aug. 13, 2025, posting a record closing high for the second straight day after mellow inflation data raised rate-cut expectations. Amazon said it would expand its same-day food delivery service to additional markets. Shares of grocery store operators and food delivery competitors fell. Paramount Skydance shares soared as analysts anticipated ambitious content and sports rights acquisition plans.

Major U.S. equities indexes gained ground Wednesday as consensus solidified around the likelihood of the Federal Reserve lowering interest rates at its next meeting.

The growing confidence in rate cuts followed Tuesday's release of soft inflation data, which likely gave policymakers more leeway to loosen monetary policy.

The S&P 500 advanced 0.3% to secure an all-time closing high for the second straight session. The Nasdaq also added on to Tuesday's record close with an uptick of 0.1%, while the Dow surged 1% to end just below its closing record established in December.

Paramount Skydance (PSKY) shares skyrocketed 37%, extending gains posted in the prior session and logging the S&P 500's top daily performance. The newly minted media giant, which began trading as a combined entity last week following a prolonged merger process between Skydance Media and the former Paramount Global, grabbed headlines Monday with the announcement of a $7.7 billion, seven-year agreement to acquire the exclusive broadcasting rights for Ultimate Fighting Championship events. Its comparatively small float led commentator Jim Cramer to call it a meme stock today, likely fueling the fire.

Shares of fellow entertainment conglomerate Warner Bros. Discovery (WBD) rose 7.4%. The company said it would partner with streaming service Viu to launch a bundling package in Southeast Asia.

Growing anticipation that the Federal Reserve will cut interest rates at its September meeting and the potential for additional cuts later this year helped bolster shares of home builders. The housing market has been pressured by elevated mortgage rates, which limit affordability for potential homebuyers, so the prospect of lower borrowing costs represents a positive signal for the residential construction business. PulteGroup (PHM) stock gained 5.4%, while shares of Lennar (LEN) added 5.2%.

Shares of electronic circuit board manufacturer Jabil (JBL) declined 4.9%, falling the most of any S&P 500 stock. Wednesday's slide gave back gains posted in the prior trading session, but even after the downtick, Jabil stock has more than doubled in value over the past year, boosted by demand for hardware related to artificial intelligence processes.
