Oracle's massive AI infrastructure spending is catching up with the company. Capital expenditures jumped to $28.5 billion last quarter, up from just $2.3 billion two years ago. To fund these chip purchases, Oracle has leaned heavily on bonds, pushing total long-term debt past $160 billion. Investors have noticed, and the stock has dropped nearly 30 percent this year as concerns about profitability mount.
Not every AI-adjacent company is facing headwinds, though. Supermicro reported record orders for AI infrastructure systems and is expanding its liquid cooling technology to manage powerful chips. Stock prices rose 3.40 percent on September 21, 2026. The key question now is whether Supermicro can maintain healthy profit margins while scaling operations at this pace.
IREN AI Cloud is also growing rapidly, driven by major AI contracts and substantial power capacity. However, investors are questioning whether the company can generate meaningful cash flow after accounting for equipment costs and loan payments. The stock fell 6.25 percent on September 22, 2026, as analysts await proof that this expansion will translate into sustainable earnings.
On the security front, Tanium relaunched its Security Operations platform to address a new wave of attacks that exploit stolen login credentials rather than traditional malware. The updated system uses data from existing IT tools to detect unusual device behavior. A feature called Endpoint Drift identifies abnormal activity, while the Insights Engine surfaces hidden threats. Security teams can now terminate suspicious processes or isolate compromised machines across their entire network.
Tanium's update comes as AI-related security risks surface in unexpected places. Epic participated in Anthropic's Project Glasswing, using the Mythos model for defensive security testing. The AI scan uncovered MyChart configurations that could allow outsiders to access patient records without triggering audit logs. Around 50 partners identified over 10,000 high or critical vulnerabilities in the first month alone. Epic redirected engineers away from product development for roughly six weeks to plug these gaps.
In the investment space, AI ETFs are branching out beyond chips and hyperscalers into memory, power infrastructure, robotics, and electronic components. About 15 AI and tech-related ETFs launched in September. The Roundhill Memory ETF (DRAM) reached $10 billion in assets faster than any ETF on record, achieving the milestone in just six weeks. Semiconductor-focused funds like iShares and VanEck pulled in roughly $11.1 billion and $8.7 billion in year-to-date net inflows respectively.
Upwork presented its AI strategy aimed at improving services and boosting efficiency, but the company's financials remain under pressure. Revenue declined 1.70 percent in Q2 2026 to $191.66 million, and the stock was trading at EUR 7.49 on October 8, 2026, over 63 percent below its all-time high. CEO Eric Blumberg emphasized AI as central to the company's path forward.
Meanwhile, Willow Care is using CoreWeave infrastructure to train AI models for its dictation application. The company fine-tunes a small language model that post-processes speech into formatted text, including handling challenging audio like whispers in noisy environments. Willow's goal is to eliminate keyboards within two years through voice-based computing.
Research into AI decision-making continues as well. Researchers studied dual-process agents that pair a fast decision-making policy with a slower deliberative model. The fast learned actor handles most decisions while a reasoning vision-language model steps in only when a gate opens. Testing took place in closed-loop Doom and a new open environment, with potential applications for turn-based agents and robot planners.
Closer to home, the Casper City Council approved a $58,800 one-year contract for TRULEO AI body-camera software. The department had been testing the platform for six months. TRULEO provides AI-assisted report writing, encounter summaries, and automated review of body-camera footage. The council approved the deal with minimal public discussion despite online criticism of AI adoption in policing.
In China, the Shenzhen Component index fell 2.1 percent to 12,621 points amid an AI hardware and semiconductor sell-off. Hengrui Automation dropped 4.9 percent and Hengrui Technology fell 4.5 percent. The sector's sub-index declined 3.4 percent, marking the steepest drop among major Chinese indices, compared with the Shanghai Composite at 1.2 percent and the CSI 300 at 1.1 percent.

Study explores when fast AI models should pause and think
Researchers studied dual-process agents that pair a fast decision policy with a slow deliberative model. The fast learned actor makes every decision while a reasoning vision-language model steps in only when a gate opens. The study used closed-loop Doom and a new open environment to test this approach. This method applies to turn-based agents and robot planners.
