1. INVESTMENT FIRMS ON AI

🔹 AI Tokens Emerge as Deflationary Commodity as Prices Keep Falling

AI tokens are an immaterial commodity whose input is cognition, with prices collapsing and no durable floor. It describes tokens as fungible, transparently priced feedstock used across industries, with prices falling from about US$30 per million tokens in early 2023 to below US$0.30 by late 2024. It says China’s daily token consumption rose from roughly 100 billion at the start of 2024 to over 140 trillion in early 2026. The article argues value is shifting to infrastructure, orchestration tools, and proprietary context, while professional services, finance, healthcare, education, and media face deflationary pressure as cognitive work becomes cheaper.

🔹 AI debt boom weighs risk against opportunity

Capital Group says AI’s capital-spending boom is driving record public and private debt issuance, led by hyperscalers. Alphabet, Amazon, Meta, Microsoft and Oracle issued $240.7 billion year-to-date through August; including SpaceX and Nvidia, total issuance reached $290.7 billion. Strong demand—from higher yields, annuity investors and foreign inflows—has kept broader US investment-grade spreads unchanged, but longer-dated hyperscaler and AI-related spreads have widened as supply grows. The authors warn that projected AI investment will exceed operating cash flow in 2027–28 and monetisation remains uncertain. They favour diversified issuers, fungible infrastructure, data-center and power suppliers, avoiding complex structures and chip debt.

🔹 AI Development Questions, Reshaping the Investment Case

Leaders of major AI companies have called for a slowdown in the race to build AI superintelligence, while the investment case has shifted from being long semiconductors and short software to stock selection within each sector. The AI race is moving from the smartest model to the cheapest to run, with cheaper open-source models, mainly Chinese, narrowing the gap to frontier models to six months. The AI supply-chain demand exceeds supply with order visibility to 2028. Cybersecurity is highlighted as a winner, while consumer AI adoption is being watched closely.

🔹 Next Great AI Companies May Resemble Services Companies

AI-native services companies sell completed outcomes rather than software seats, using software, models, agents, and human operators to deliver jobs such as insurance, bookkeeping, benefits access, home maintenance, compliance, and procurement. The article argues SMBs are attractive customers because they often want the responsibility removed entirely and already spend heavily on outsourced services. Examples include Corgi, which provides startup insurance, Mindset Care, which handles SSI and SSDI applications at no upfront cost, and Casa, a home-services platform built around a digital home record, concierge layer, and managed vendor network. These businesses may initially resemble services revenue, but their marginal delivery costs can decline as software takes on more work.

🔹 Blue Owl executive perspectives: The future of enterprise software with Anaplan

Blue Owl’s Erik Bissonnette and Anaplan CEO Charlie Gottdiener said AI is reshaping enterprise software, but Anaplan’s value remains its “system of decision” with auditable, deterministic outputs for CFOs. Its calculation engine provides 100% repeatable answers and can model complex, real-time variables such as supply chain disruptions, oil price shocks, and tariffs. Anaplan serves half of the Fortune 50, including Nvidia, OpenAI, Microsoft, and Google. It views AI providers as partners and acquired Syrup Tech for retail forecasting. Enterprises want AI embedded in proven platforms at predictable cost.

🔹 How Investors Can Diversify Away From AI

Artificial intelligence remains a promising investment theme, but the article says rising capital intensity, increasing leverage, and greater competition warrant caution. Following the recent Russell reconstitution, AI infrastructure beneficiaries make up about 36% of the Russell 1000 Growth Index, and hyperscalers add another 22%, for nearly 60% total AI exposure. By contrast, the S&P 600 Small Cap Index has about 5% direct AI infrastructure exposure and no hyperscalers. Outside the U.S., the MSCI Emerging Markets Index has about 36% AI infrastructure exposure, while the MSCI EAFE Value Index has almost none. The Asset Allocation Committee is overweight U.S. small caps and non-U.S. value equities.

🔹 Emerging-Market Debt: Next Frontier for AI Disruption?

Industries with low risk of functional displacement and clear AI tailwinds include metals and mining, software, and hyperscalers. Because AI is resource-intensive, copper mining and energy production in commodity-rich countries may benefit from rising demand, while media, entertainment, and online platforms face risks to discovery and advertising models from AI-driven search and agentic interfaces. Financial-services issuers are in between, with brokerages, asset managers, and exchanges facing partial erosion of informational advantages, though licensing, regulation, and scale remain barriers. For sovereigns, the framework focuses on structural leverage in AI supply chains, with Asian emerging markets showing the strongest indicators and some EMs exposed through power, thermal management, and data-center components.

🔹 Climate Scientist David Victor on AI Data Centers and Resources, Part 2

David Victor of UC San Diego and the Brookings Institution said AI data centers are driving steep U.S. electricity demand growth, approaching 5% of total power demand and about 4% to 5% of total emissions, similar to airlines. He said many data centers turn to natural-gas-fired generators because power must be obtained quickly, though some companies also seek renewables, batteries, and small modular reactors. He added that speculative interconnection requests are complicating grid planning, while data centers are also pushing for more responsive electricity use and, in his view, do not create a major water-consumption problem.

🔹 AI Adoption Widens as Spending Concentrates

Ramp data show AI adoption broadening but expenditure remaining highly concentrated. About 10% of software-spending businesses now pay a GPU vendor, versus under 4% two years earlier, driven mainly by model serving and inference, whose share rose from 2.4% to 8.7%. Neocloud use increased modestly, while wholesale GPU capacity remained negligible. Most companies therefore consume AI as cancellable, usage-based software rather than reserving infrastructure. The top 10% of customers generate 99.5% of model-serving spend and 99% of neocloud spending; the bottom 90% contribute almost nothing. Unlike SaaS or CRM, AI costs track runtime, leaving infrastructure reliant on heavy users today.

🔹 Can AI Investment Drive S&P 500 Earnings Higher?

Goldman Sachs Research says S&P 500 earnings growth should decelerate, not collapse, and forecasts the index will rise to 8,700 over 12 months from 7,764 on September 21. The forward P/E has fallen from 23 times a year ago to 19 times, matching its 10-year average, while the cyclically adjusted P/E is near a record high. S&P 500 EPS are forecast to grow about 11% in both 2027 ($415) and 2028 ($460). The firm says almost half of 2026 EPS growth comes from AI investment, with hyperscaler capex at $800 billion this year, expected to reach $1.2 trillion in 2027 and $1.4 trillion in 2028.

🔹 Unexpected Investment Case for AI Safety

Morgan Stanley’s Ariana Salvatore said AI safety scrutiny is more likely to boost compute spend and CapEx than slow it, as labs add safety-monitoring infrastructure. She sees little chance of a comprehensive AI regulation bill or sweeping open-weight rules, citing presidential opposition, weak legislative vehicles, and the need for a high-salience incident. Data-center pushback is mainly about environmental and affordability issues, not safety, and she expects AI CapEx to remain constructive this year and next. Midterms may affect sentiment, but policy direction depends more on event salience than government control. Investors should favor inference compute bottlenecks, cybersecurity leaders, and AI adopters.

🔹 Anthropic Says Claude Discovers Novel Enzyme System With CRISPR-Like Repeats

Anthropic formed a life sciences research group and lab in spring 2026 to use Claude for fundamental biology research, including DNA database searches and lab testing. In one program, Claude searched for 21 hours with roughly 950 agents and 210 million tokens, then identified a previously uncharacterized bacteriophage enzyme system called array-associated reverse transcriptses (ART). ART is based on a reverse transcriptase and includes a partner gene and a long array of evenly spaced DNA repeats, resembling CRISPR. Early experiments found the ART array is expressed as distinct short RNAs.

🔹 Salesforce Plans to Thrive in an AI World After the “SaaSpocalypse” Ends

At Dreamforce in San Francisco, Salesforce said it is adapting to an AI-focused enterprise landscape by making its apps and data accessible to agents through tools such as Claude, Slack, ChatGPT, and Agentforce Coworker. CEO Marc Benioff said customers want different pricing models, including per user, per agent, consumption, usage, transaction-outcome, and business outcome pricing, and Salesforce is giving sales teams flexibility to negotiate. The company left guidance unchanged, including a fiscal 2030 revenue target of at least $63 billion. Barclays kept a buy rating and $276 price target, while William Blair said consumption or outcome-based pricing may be most popular.

🔹 AI Tightens Consulting Teams and Raises the Bar for Membership

IBM introduced Forward Deployed Units, or FDUs, small teams of three or four specialists working with 10-20 AI agents to build and deploy AI systems directly with clients. Gartner said only 22% of organizations had scaled AI across multiple business units or adopted an AI-first approach, while 85% of functional leaders planned to increase AI spending in 2026. IBM’s Institute for Business Value reported an average AI ROI of 17% for enterprises in 2026. IBM said an India bank data modernization project that might have needed about 300 people for 12 to 15 months was completed in less than nine months with a fraction of that team.

🔹 Shadow AI Reaches the SOC, Making Security Teams Their Own Blind Spot

The article says analysts in security operations centers may paste sensitive incident data, such as internal hostnames, service account names, file paths, IP ranges, detection rules and live-incident indicators, into personal chatbots to speed up work. It warns this shadow AI can leak information to unreviewed outside services and can also lead analysts to inherit AI mistakes. It cites research that employees enter sensitive data into AI tools about once every three working days, nearly half of generative AI users use personal accounts, and heavy shadow AI use adds about $670,000 to breach costs. It argues bans fail and approved, managed AI channels work better.

🔹 Private Processing Comes to Meta AI Glasses

Meta said AI glasses need cloud-based processing for stateful, personal, and advanced features such as translation, transcription, contextual search, and long-term recall. In 2026, it described Private Processing, its confidential-computing infrastructure for AI workloads, which runs models inside confidential virtual machines so even Meta cannot access user data. The system uses TEEs, remote attestation, anonymous credentials, encrypted storage, and public transparency ledgers, and it is built around five requirements: hardware isolation, fail-closed guarantees, public verifiability, non-targetability, and encrypted storage. Meta said it had introduced Private Processing for WhatsApp and the Meta AI app in 2025.

🔹 Science Says Claude Can Do Nine Loops

Physicist and science writer Matt von Hippel challenged AI companies to solve a frontier problem in theoretical particle physics: the six-particle amplitude in planar N=4 super Yang-Mills at nine loops. In late August, Anthropic’s Liam Fitzpatrick and Siddharth Mishra-Sharma used Claude Science with Fable 5.1 to compute it, costing about $1,000–$2,000 for an end user and about $100 of that on a bootstrap run using 96 CPUs for a week. Lance Dixon independently validated the result. Soon after, Song He’s group reported they had also gotten most of the result, with some AI assistance based on GPT-6.

🔹 Evaluating AI Agents From Tool Calls to Task Completion

The article says agent evaluation has shifted from scoring single function calls to scoring full tasks executed through tool use, because agents operate across multi-step environments and can recover from failures. It distinguishes step-level scoring, which checks whether each call was valid and useful, from end-to-end scoring, which checks whether the final state shows the task was completed. It also notes that benchmarks now vary by task complexity, statefulness, and methodology, and that executable verification is preferred when available. Public suites, domain-specific evaluations, and real environment state are presented as the best way to judge whether a model can complete work.

4. SELECTIONS FROM ARXIV

🔹 Anytime-Valid Referee for LLM Agents Mining Investment Factors

The paper “Propose, Don’t Judge: An Anytime-Valid Referee for LLM Agents That Mine Investment Factors,” submitted on 22 Sep 2026 by Bo Qu, Mingguang Chen, and Licheng Wang, studies a governed self-evolution setup in which an agent may propose investment factors while a frozen statistical referee judges them. The referee scores candidates only on post-submission market outcomes and provides a false-discovery guarantee at every stopping time. In tests with a script, bandit, and language model, the frozen referee admitted 5–11 times fewer sub-threshold factors than leaky referees under a scripted proposer, but certified true factors waited about 500 trading days.

🔹 Financial Language Models for News-Based Trading Under Market Frictions

Kemal Kirtac’s paper introduces MFAST, a Market-Friction-Aware Sentiment-to-Trading framework that converts timestamped financial text into auditable and reproducible trading decisions. The framework links Refinitiv News Analytics with CRSP equity data, limits primary out-of-sample evaluation to post-release news outside disclosed foundation-model data-freshness periods, and includes a public replication arm using open financial text and public price data. The results show decoder-only language models outperform encoder baselines and dictionary sentiment in classification, calibration, return prediction, and net portfolio performance, while diagnostics show trade-offs among accuracy, latency, memory, throughput, and inference cost.

🔹 Designing Agentic AI Workflow Portfolios Under Imperfect Selection and Compute Costs

Mojtaba Abdolmaleki, Stefanus Jasin, and Boyu Wang presented a paper on designing agentic AI workflow portfolios under imperfect selection and compute cost. The study examines a portfolio-and-selector approach in which multiple workflow executions are run and the final answer is chosen after observing outputs, balancing improved accuracy against compute cost and distractors. The authors derive bounds, exact formulations, linear programming relaxations, randomized rounding procedures, and performance certificates, and also develop a finite-dimensional dual and ellipsoid method for large workflow classes. On ABCD, Schema-Guided Dialogue, and HotpotQA, portfolio optimization improved held-out selector accuracy by 3.1, 7.5, and 0.9 points, respectively.

🔹 TimeEvo Uses Failure-Driven Self-Evolution for Time Series Agents

TimeEvo is a proposed failure-driven self-evolution method for time series agents that use external tools. The paper reports two problems in current setups: a 21-tool expert-curated library improves some tasks but hurts others, dropping anomaly accuracy across every tested backbone, and one round of generic self-revision changes 147 answers, breaks 56, and shifts the final score by less than one point. TimeEvo clusters diagnosed failures into capability gaps, plans measurements, synthesizes evidence-only tools, and admits candidates through a paired gate. Experiments on ten time series QA tasks and three backbones show improved accuracy on every task and backbone, starting from an empty library.

🔹 Adversarial Context Manipulation of LLM Pricing Agents

The paper introduces market signal injection (MSI), an attack on LLM pricing agents that changes numerical formatting, competitor ordering, or qualitative market commentary without explicit instructions. The authors evaluate nine open-weight models in simulated Bertrand duopoly and triopoly markets and three proprietary models in duopoly markets. Sentiment-based attacks produce the largest behavioral shifts, affecting other firms as well as profits and consumer surplus. Susceptibility varies across model families, and larger models are not consistently more robust. Episode-held-out probes separate baseline from attacked activations in all eleven re-evaluated model-condition pairs, with linear AUC 1.00 and MLP AUC 0.93 to 0.99.
