Anthropic recently submitted a draft AI safety bill to U.S. lawmakers, which has been questioned by U.S. AI safety advocates. The draft sets a high threshold for the government to urgently halt dangerous models, requiring that risks involve scenarios such as biological weapons, cyberattacks, or AI going out of control, and potentially causing more than 50 deaths or serious injuries, or losses exceeding $1 billion; some provisions may also limit state government regulatory authority.Nathan Calvin, the strategic head of the AI safety organization Encode, subsequently compiled Anthropic's decisions over the past year. In February of this year, the company modified its previously strict safety policy: it had previously committed to pausing training or releases if safety measures did not keep pace with model capabilities, but the new policy no longer requires the company to independently halt R&D at higher risk stages, citing that competitors might take advantage of the opportunity. During the same period, the company invested heavily in computing power, formed a chip team, and allowed Claude to take on more AI R&D tasks.On October 21, Anthropic CEO Dario Amodei posted a lengthy rebuttal on X. He acknowledged that the company had made some mistakes but insisted that competing for cutting-edge AI capabilities did not violate its safety mission, stating that the company adheres to a race-to-the-top approach, believing that only by staying at the forefront of technology can it drive the industry to raise safety standards. He listed nine safety decisions that had cost the company commercially, including restricting the Mythos-level model's open access for months and strictly limiting biology-related requests. The safety roadmap updated by the company on October 19 states that existing policies mainly target the deployment of dangerous models, and in the future, it may be necessary to directly limit the speed of R&D, with plans to propose relevant policy options by January 15, 2027, or explain why none were proposed.

Cryptocurrency researcher Kerman Kohli published "Compute Financing" on Substack on October 19, 2026, discussing financing for computing power construction. He believes one of the main bottlenecks is capital, especially credit: early expenditures mainly come from balance sheet cash, followed by a shift to equity financing. The article cites Alphabet's $85 billion financing and Meta's fundraising through shareholder dilution, with the next step being the credit market.Kohli summarizes the current beliefs of creditors into three points, which he believes are incompatible: AI may be a bubble; the biggest risk is counterparty risk in purchase contracts; the underlying GPUs are not valuable and depreciate like ordinary hardware. He argues that demand is closer to infinite, stating that the demand for agentic AI is growing by about 2.5 to 5 times each year, with supply potentially doubling by the end of 2030. Memory is expected to sell out by 2027, with computing power commitments reaching trillions of dollars, and he mentions Jane Street's multi-billion dollar commitments, as well as the needs of pharmaceutical companies, research, military, and cybersecurity.Regarding efficiency, he states that when the cost of intelligence drops by 90%, the increase in usage is even greater, with a baseline exceeding 10 times, and he cites Jevons' Paradox.On the topic of purchasing, Kohli believes that computing power is more substitutable than real estate; when demand is strong, if someone withdraws their commitment, others will take over. He mentions that many creditors require 2 to 3 year contracts and down payments of 20% to 30%, sometimes as high as 50%, and locking in long-term discount contracts effectively shorts computing power for lenders. The article also states that computing power rental prices have risen by about 50% in the past 6 months and about 100% in the past year, with B300 supplies being tight. Regarding collateral, he notes that the A100 from 2020 is still operational and rented out until 2029, leading him to believe it has at least about 9 years of use value; the current price of B200 is about 50% higher than when it was released about two years ago, and a 6-year-old A100 is still worth about 25% of its value. He concludes that computing power will surpass real estate to become the largest asset class, and the scale of credit-supported computing power is currently just beginning.

Mark Newton, an analyst at Tom Lee's fund, stated in an interview with CNBC that it is currently suitable to buy technology stocks on dips, but investors need to maintain diversified allocations and be prepared for sector rotations.In the past month, cross-asset volatility has significantly increased, with the S&P 500 index recently falling about 6%, and the technology sector also experiencing notable adjustments over the past week. However, compared to the gains in September, he believes the damage to technology stocks has been relatively limited.This year, the market has consistently shown characteristics of sector rotation, initially with the energy sector rising nearly 40%, then the momentum spreading to the technology sector, and now shifting towards the healthcare sector, which has reached an all-time high. Investors need to be prepared for sector switches and maintain diversified allocations.Steve Sosnick, Chief Strategist at Interactive Brokers, reminds that even if investors do not actively allocate to AI, they may still hold a high exposure to technology stocks through S&P 500 index funds. Currently, the market remains focused on sector rotation, but he is concerned about the continued decline of technology stocks and that investors are beginning to question the return on AI investments.
