The model's market view
US equities are under pressure on September 14, 2026, as AI safety warnings from Anthropic, OpenAI, and xAI leaders triggered a sharp selloff in semiconductor and AI infrastructure names, with Nasdaq-100 futures down over 1.5%. Brent crude climbed above $108 amid Middle East supply disruptions, while the Fed's rate hike decision looms on Wednesday. The market is risk-averse, but idiosyncratic catalysts in defense, biotech, and cybersecurity are creating strong relative winners.
Why each pick
ELMT
Elmet Group surged over 46% in premarket trading after announcing a $450 million committed investment from the US Department of War to expand domestic tungsten manufacturing, along with a separate contract worth up to $2 billion from the Defense Logistics Agency to supply tungsten for the National Defense Stockpile. This is a direct national security catalyst with hard government funding, making the move highly credible and likely to sustain through the session despite broader market weakness. Risks include profit-taking after an outsized premarket gain and execution risk on the manufacturing expansion.
RUM
Rumble (RUM Group) jumped as much as 28% in premarket trading after The Information reported that Anthropic entered into a $13.7 billion, six-year computing contract with the company. Rumble had previously disclosed a $13.7 billion contract in an August securities filing but did not identify the customer, so this confirmation from a major AI player validates the deal. The stock is a direct beneficiary of AI infrastructure demand despite the broader AI slowdown narrative. Risks include the controversial political associations of the company and the possibility of the deal being repriced or delayed.
SRRK
Scholar Rock surged 9.1% in premarket trading after receiving FDA approval for Isembyld (apitegromab) as the first and only muscle-targeted treatment for spinal muscular atrophy in adults and children aged two and older. The approval came weeks earlier than expected, and analysts at BMO and Truist highlight the broad label and differentiated efficacy, with peak sales estimates reaching $2.3 billion. Biotech catalysts are largely immune to macro AI worries, giving this stock a strong idiosyncratic driver. Risks include the drug's pricing announcement and potential profit-taking after the premarket jump.
CRWD
CrowdStrike advanced 5.4% in premarket trading as cybersecurity stocks broadly rallied on increased AI safety concerns. The warnings from AI leaders about the risks of rapid AI development are driving demand for cybersecurity solutions as enterprises seek to safeguard against AI-related threats. CrowdStrike is a high-quality software name with recurring revenue and is benefiting from a rotation out of hardware chip stocks into software. Risks include the broader tech selloff dragging down software names and the stock giving back gains if the AI safety narrative fades.
NOW
ServiceNow rose 3.5% in premarket trading as software stocks moved higher on the view that slower AI development could ease disruption concerns for enterprise software companies. ServiceNow is a leading workflow automation platform with strong AI integration, and the rotation into software from semiconductors is providing a tailwind. The stock is a relative safe haven within tech during the AI selloff. Risks include the broader market decline accelerating and pulling software lower, as well as the stock's high valuation leaving it vulnerable to a reversal.
