Citrini Research was acquired by SemiAnalysis, and its founder plans to launch a new fund.

The U.S. Commodity Futures Trading Commission (CFTC) has secretly approved at least three insider trading investigations into Polymarket trades, targeting contracts related to Biden pardons, the Iran war, and Google-linked events. The investigative documents were obtained by WIRED via the Freedom of Information Act (FOIA). Among these probes, CFTC Chair Michael Selig approved the investigation into Biden pardon-related contracts in May, after a trader earned over $300,000 in profits from the relevant market. That same month, the CFTC also greenlit an investigation into Iran war contracts, following reports that a group of suspicious accounts had reaped $2.4 million in profits with a roughly 98% win rate. In July, the CFTC launched an additional probe into Google-linked Polymarket contracts, focusing on individuals who may have traded using non-public information about Google’s 2025 search rankings. The U.S. Attorney’s Office for the Southern District of New York is also conducting a parallel investigation. It remains unclear whether the aforementioned accounts are linked to individuals previously under investigation. Polymarket stated it will refer the matter to law enforcement and cooperate with the probes. As prediction markets expand rapidly, U.S. regulators are significantly stepping up scrutiny of insider trading and market manipulation.

After a key oil pipeline was attacked, Saudi Arabia announced the temporary shutdown of its 1,200-kilometer east-west oil pipeline. The pipeline connects major oil fields in eastern Saudi Arabia to Yanbu Port on the Red Sea, serving as a key route for Saudi crude exports bypassing the Strait of Hormuz. The Saudi Ministry of Energy described the shutdown as a "precautionary measure", with no timeline for resumption announced. The Saudi Foreign Ministry said the pipeline was hit by a drone attack from the Iraqi side, and that Saudi Arabia will not retaliate for now. Meanwhile, Iran-backed Houthi forces have recently carried out repeated attacks on Saudi energy facilities and advanced toward the Bab el-Mandeb Strait, further raising shipping risks in the Red Sea. Oil markets have quickly priced in the supply risks. Brent crude closed at $104.56 per barrel on Friday, with a weekly gain of over 8%. Saudi Arabia’s crude exports via Yanbu Port stood at just around 2.5 million barrels per day in August, the lowest level since 2013. With alternative export routes blocked, Saudi Arabia’s crude supply capacity faces further downward pressure. As two major energy shipping routes—the Strait of Hormuz and Bab el-Mandeb Strait—face risks simultaneously, markets are reassessing the likelihood of global crude supply disruptions.

Beating AI News Flash: OpenAI Codex Product Lead Tibo has issued an update addressing recent quality complaints from Astra users, stating the team has identified and fixed multiple defects and will perform a reset by midnight local time (12 PM Beijing Time). Tibo noted that after collaborating with some users, the team confirmed and resolved the following issues: 1) Old model skill triggering anomalies: Skills built for previous models were triggering too frequently, or preventing the model from reviewing its own work. 2) Context management experiment disabled: An optional context management experiment could cause premature termination or outdated message responses, and has now been turned off. Rough estimates indicate approximately 4,000 to 5,000 users were affected by this experiment. 3) Misconfigured engines removed: Some engines were improperly set up, leading to measurable quality declines in tail-end traffic flowing through them, and have now been removed. Additionally, the team has made several minor improvements, saying the overall experience should see noticeable enhancements, including more consistent execution, more accurate tracking of users’ latest messages, and better result checks during workflow progression.
