In policy news, President Trump disclosed major stock and bond transactions and stated the U.S. will not attack Iran before the midterm elections.

OpenAI's Annualized Revenue Is $20 Billion Lower Than Previously Reported

According to the Financial Times, OpenAI recently disclosed to investors that its annualized revenue was close to $50 billion as of the end of September, significantly lower than the $70 billion reported by the newspaper and other media late last month. People familiar with the matter said the difference stemmed from investors attempting to make direct comparisons between the annualized revenues of OpenAI and its rival Anthropic, but the two companies use different accounting methodologies: Anthropic includes sales generated through cloud partners such as AWS and Google Cloud in its revenue, whereas OpenAI does not. Previously, investors adjusted OpenAI's revenue methodology to calculate that its annualized revenue reached $40 billion in August, and subsequently extrapolated $70 billion based on disclosures to investors that revenue grew by more than 70%. OpenAI declined to comment.

Trump Bought Up to $25 Million in Meta Stock in August

The documents also disclosed that Trump's accounts purchased $1 million to $5 million in SpaceX bonds on August 18.

Fed's Waller: Further Rate Hikes Still Needed to Bring Inflation Back to 2% Target, But Hikes Need Not Occur at Consecutive Policy Meetings

Federal Reserve Governor Christopher Waller stated that the Fed still needs to raise interest rates further to bring inflation back down to its 2% target, but rate hikes do not need to occur at consecutive policy meetings, allowing officials to flexibly time their moves based on economic data. Speaking Thursday at an event organized by the Central Bank of Turkey in Istanbul, Waller said that if economic data continues to meet expectations, he expects further rate hikes will be required, but these do not need to be scheduled at back-to-back meetings and should instead be completed within a reasonable timeframe. Waller also noted that the 2027 dot plot might reflect a trajectory of raising rates early in the year followed by cuts. He pointed out that the forecasts released in September showed the median Fed official expected one more rate hike this year, but cautioned that when interpreting the 2027 dot plot, some officials' projections may incorporate rate hikes early in the year followed by cuts later in the year.
