The Kobeissi Letter: Fed Governor Waller May Be Constrained by Trump, Market Overestimates Likelihood of a September Interest Rate Hike

Beating AI Express News: OpenAI has responded to the Navier-Stokes credit dispute, explicitly denying it improperly used unpublished research from New York University mathematician Tristan Buckmaster. Following an internal investigation, the company stated that prompts Buckmaster submitted to Codex over the past two months could not have impacted its internal model in any way, including via training. Buckmaster and Levent Alp?ge had been working on the same research area, uploading numerous drafts to Codex. After their progress reached OpenAI, the company deployed concentrated computing power to produce a Navier-Stokes proof within days. Buckmaster thus suspected his unpublished research had been incorporated into the model, a claim OpenAI has now explicitly rejected. OpenAI also set a timeline boundary at July 3, noting that any user input after that date could not affect the system. Some community members have speculated this date may correspond to a training data cutoff or model checkpoint, though OpenAI has not provided an explanation. The key breakthrough by Buckmaster and Alp?ge occurred in mid-August, far later than the July 3 boundary set by OpenAI.

According to Bitget market data, Brent crude oil plunged 4.00% on the day, currently trading at $101.92 per barrel. However, on the news front, two Yemeni government sources said that Yemeni government forces have withdrawn from Perim Island in the Bab el-Mandeb Strait, and the Houthi armed group has taken full control of the Bab el-Mandeb Strait. A spokesperson for the Houthi group stated that it will announce a major military operation.

Saudi Crown Prince made two calls to Donald Trump on Thursday, urging the US military to strike Houthi forces advancing toward the Strait of Mandeb, but Trump rejected the request, citing a focus on countering Iran and the Strait of Hormuz. Analysts note the move marks Saudi Arabia’s shift from a "self-reliant response" in July to seeking external assistance, amid recent Houthi seizures of strategic sites and attacks on Saudi oil facilities that have elevated the Yemen battlefield’s new threat to global energy shipping routes. The US has only provided intelligence support in the incident, avoiding direct involvement, a move that reflects the Pentagon’s concerns over tight missile stockpiles and its multi-front combat capabilities, which could push up oil prices and exacerbate strategic rifts among Middle Eastern allies.
