On July 3, 2026, Alibaba suddenly hit the brakes. According to leaked risk assessment results, due to the disclosure of a backdoor risk in Claude Code, Alibaba listed it as high-risk software and subsequently banned all related Anthropic products from the office environment. This Chinese internet giant, which had been strongly encouraging "everyone to use AI" internally for the past six months, made this about-face swiftly, sending a significant signal throughout the industry. More dramatically, on the same afternoon, the semiconductor equipment sector in the domestic stock market rebounded, with Yitang Co. seeing a rise of over 8%, while across the ocean, U.S. stock futures generally strengthened — the Nasdaq 100 index futures rose by over 1%, and the S&P 500 and Dow Jones futures also increased by 0.38% and 0.2%, respectively, showing that market sentiment towards computing power and equipment remained strong. Driven by security incidents, Alibaba chose to tighten its front-end AI tool usage, while global capital continued to pour into semiconductor equipment and storage chips as AI infrastructure, creating a core contradiction that all subsequent narratives would not be able to bypass.
From Full Encouragement to Emergency Ban: Alibaba's Sudden Turn on AI Tools
At the beginning of 2026, Alibaba was sending a different signal to its employees. The company encouraged the widespread use of various AI tools in office scenarios at nearly all levels, viewing them as a new infrastructure for enhancing efficiency and competitiveness. Teams habitually opened AI assistants while coding, making plans, or organizing data, with "use more, try more, explore more" becoming a default consensus. Products like Claude Code quickly gained a foothold among engineers, as it seemed that merely filling the front-end tool stack would allow companies to capitalize on this wave of intelligent dividends.
The turnaround occurred in the early morning of July 3. After news broke of backdoor risks in Claude Code, Alibaba quickly completed an internal assessment under its safety and compliance framework, listing it as high-risk software, and on the same day issued a notice to the entire company: starting July 10, the use of Claude Code and other Anthropic-related products would be comprehensively banned in the office environment. This ban was not merely a simple "delete a software," but provided alternative paths — internally recommending a switch to Qoder, while particularly emphasizing localization and self-control directions, hoping to transition reliance on external black-box tools to a bet on manageable and controllable local solutions. This abrupt turn from full encouragement to emergency ban within just six months clearly exposed Alibaba's true prioritization between efficiency pursuits and security bottom lines.
The Vulnerability of the AI Tool Supply Chain Exposed by a Ban
When the internal notice was issued on July 3, listing the Claude series as "high-risk software," what was truly exposed was not a flaw in a specific tool, but the fragile structure of the entire AI tool supply chain for large enterprises. Since the beginning of 2026, Alibaba had strongly encouraged employees to use various AI tools internally, deeply embedding external products like Claude Code into R&D, documentation, and even decision-making processes. Once a backdoor risk was disclosed from a single source, the safety compliance assessment rapidly flipped to "comprehensive ban," forcing the entire work system relying on external black-box capabilities to be dismantled and reorganized within days. This ban was essentially a corporate safety compliance event rather than a unified directive from regulatory authorities. However, it was sufficient to show other major companies that when key productive links are dependent on external models, any single-point security event could amplify along the data, code, and process layers, becoming a systemic risk that must be addressed immediately.
Following the ban, Alibaba internally recommended the more localized and controllable Qoder as an alternative. The message conveyed would directly influence the third-party AI tool ecosystem and future corporate procurement decisions. For external AI service providers, simply being "user-friendly" and "advanced" is no longer enough; major clients will prioritize hard metrics such as auditability, local deployment capability, and parallel backups during the bidding phase, to reduce the possibility of being "choked" by a single external tool. For buyers like Alibaba, the restructuring of the supply chain has transitioned from an abstract slogan to concrete actions: shifting from comprehensive reliance on a handful of overseas tools towards a combination architecture of self-developed solutions in parallel with external services, capable of switching at any time. In this sense, the ban on July 3 became a stress test for the AI tool supply chain; those who can offer sufficient transparency, practicality, and replaceability would qualify to stand at the forefront of the next round of enterprise-level AI procurement.
The Semiconductor Sector Rebounds in the Afternoon: AI Infrastructure Expectations Ignite A-shares
While the software ban was being interpreted at various levels internally at Alibaba, capital on the other side of the market had already provided its own answer: redirecting attention to the most fundamental computing power workshops. In the afternoon of July 3, the domestic semiconductor equipment sector rebounded from prior adjustments, with multiple intraday retracements followed by renewed price gains, creating a "bottom-fishing rally" trajectory, and funds were noticeably building their positions along the equipment mainline. Yitang Co. saw a rise of over 8% on that day, becoming the first to break out from the consolidation range, marking it as a symbolic stock in this round of recovery, with its performance almost serving as a concentrated pricing of the market's outlook on future computing power and equipment demand.
Fund preferences were also fully exposed in this round of market recovery: compared to the uncertain application and tool layers, visible and measurable physical devices were seen as the most core and "safe" beneficiary direction for investment in AI infrastructure. Whether it’s upstream process equipment or various critical devices supporting computing power clusters, as long as they can be included in the production processes required for large model training and inference, they have gained premium expectations in this afternoon bounce. On the same day in overseas markets, U.S. stock futures overall strengthened, providing a relatively favorable external environment for risk assets. However, from existing data, there appears to be no verifiable direct causal relationship between Alibaba's internal ban decision and the trend of the equipment sector; rather, they seemed to be two main lines being accelerated under the same time window: one tightening software security boundaries on the enterprise side, and the other capital increasing input in computing power and equipment, the most certain hardware infrastructure.
U.S. Stock Futures and SK Hynix: Global Capital Lays Out Around AI Mainline
The U.S. stock futures on July 3 represented a global sentiment indicator for funds. The Nasdaq 100 index futures rose over 1%, S&P 500 futures increased by 0.38%, and Dow Jones futures were up 0.2%. In the absence of other strong variables, such synchronized upward movement was hard to interpret outside the "AI mainline" — the technology-weighted Nasdaq futures leading the charge seemed more like funds pricing in expectations for computing power and related hardware prosperity over the coming years, rather than reacting just to a single company's event in the short term.
Almost within the same time window, Korean memory giant SK Hynix was explicitly named as a core beneficiary of this round of AI infrastructure investment. KB Securities analysts, including Jeff Kim, predict that as AI infrastructure investment continues to accelerate in the latter half of the year, the upward trend in SK Hynix’s profits and stock prices "is far from over," driven by a supply-demand curve extended to the end of 2028: analysts forecast that the shortage of memory chips will persist until the end of that year. Under this assumption, the quicker investment in computing power and storage will be more beneficial to a select few companies that hold capacity and technology; SK Hynix's bargaining power and profit elasticity amid a long-standing supply gap will be magnified, giving global funds ample reason to view it as a medium to long-term stake in the hardware foundation of the AI era.
From Alibaba to SK Hynix: Bets on Computing Power and Storage Under Security Shadows
On July 3, the Claude Code, which was viewed internally at Alibaba as a source of risk, was quickly reclassified from a "tool for enhancing efficiency" to "high-risk software." The top-down decision to ban it was implemented within a week, accompanied by a recommendation for a more localized alternative, Qoder. This marked a contraction action taken by a giant under safety and compliance pressure: transitioning from once encouraging "the extensive use of various AI tools" to streamlining, filtering, and controlling them. Yet at the same time, the emotions reflected on trading screens presented a different picture — the A-share semiconductor equipment sector rebounded in the afternoon, with Yitang Co. rising over 8%; shortly thereafter, Nasdaq 100 futures jumped over 1%, and S&P 500 and Dow Jones futures also strengthened in unison, with capital refocusing on the devices and storage directions viewed as core beneficiaries of AI infrastructure.
This juxtaposition outlines a clear tension line: on one end is the fast response of enterprises to localized security incidents, willing to sacrifice some application layer efficiency to isolate potential backdoor risks from the office environment; on the other end is global capital pursuing long-term prosperity in computing power and storage. In analysts' views, SK Hynix will continue to reap dividends from the accelerated investment in AI infrastructure in the latter half of the year and maintain an upward trajectory in profits and stock prices amidst an anticipated continued shortage of memory chips extending to the end of 2028. The tightening of safety and compliance constraints has not weakened this hardware mainline; rather, it might invisibly alter fund preferences: as specific application tools are frequently scrutinized, replaced, or classified as "high-risk," more institutions may lean towards placing stakes on relatively "neutral" underlying computing power and storage capacities, transforming optimism about AI into bets on the long-term bargaining power and cyclical continuity of infrastructure companies.
The Long-Term Game Between Security Red Lines and the AI Investment Frenzy
Alibaba's emergency ban of Anthropic products on July 3 quickly pushed a tool originally viewed as an efficiency weapon to the "high-risk software" position. This reversal will influence corporate AI selection logic for a long time: safety is no longer an ancillary clause but the first threshold that precedes function and price. In a landscape where there are currently no new regulatory norms and more reliance on enterprises to define security red lines, a single backdoor controversy is enough to force large technology companies to rewrite their internal tool lists, or even promote alternatives like Qoder that have a stronger localization character, much like Alibaba did. In contrast, on the same day, capital markets continued to bet on underlying computing power and storage — A-share semiconductor equipment sectors rallied, Yitang Co. led in gains, and U.S. stock futures overall strengthened, with analysts optimistic about SK Hynix benefiting in the long term from accelerating AI infrastructure investments and ongoing memory chip supply tension until the end of 2028. The tightening of safety and compliance has not altered this hardware mainline. It is foreseeable that the future AI tool ecosystem will evolve along "three-fold tightening": first, emphasizing source control, where enterprises tend to choose products with more transparent technology routes and supply chains; second, emphasizing process visibility, incorporating model behavior into a accountable framework through logs, permissions, and compliance audits; and third, emphasizing deep binding with proprietary computing power and storage, running key applications within the hardware bounds under their control, translating abstract security red lines into a long-term game over the controllability, transparency, and degree of mastery of underlying hardware.
