AI & Hardware — Stock Market
NVIDIA, Alphabet, Intel, AMD, Microsoft, Broadcom, Arm, TSMC, Oracle and Amazon: share prices, daily changes and charts for the AI and computing industry. Select a company to explore its market information.
Market data and charts by TradingView. Data loads directly from the provider when this section comes into view. Quotes may be delayed; when markets are closed, the latest available session remains visible. Refresh the page to reconnect.
All symbols shown are US-listed and quoted in USD. TSM represents TSMC’s US-listed depositary shares (ADR). These market indicators provide economic context, not a ranking of AI capabilities or investment advice.

Semiconductor market
VanEck Semiconductor ETF (SMH) brings together US-listed semiconductor and semiconductor-equipment companies, including international firms. An ETF is an exchange-traded fund: its share price offers a view of a basket of companies rather than a single business.
Chart by TradingView · Official fund information — VanEck. This is the US fund, quoted in USD, not its European UCITS counterpart.

A price chart does not include all distributions or represent the whole semiconductor industry. For editorial context, not investment advice.

AI infrastructure — bond market
CoreWeave specialises in GPU cloud infrastructure for training and running AI models. Oracle combines GPU computing with a broader enterprise business in databases, cloud services and applications. Amazon (AWS), Alphabet (Google Cloud) and Microsoft (Azure) also operate extensive cloud platforms within diversified groups. The bonds below represent debt of the named issuer as a whole; they do not isolate the performance of its AI activities.
How this updates: the table records fixed coupons and contractual maturity dates. The interactive chart below requests market data directly from TradingView / Bonds.com when it loads. Updates depend on the source; quotes may be delayed or indicative, and a bond with no new observations can retain an older value. Use Refresh chart to request the chart again.

Common basis: USD, fixed-rate, non-convertible senior unsecured notes; the same market-data source and daily chart interval. Compare YTM with YTM, or price with price, over the same dates. The four 2032 issues have closer maturities; Microsoft’s 2030 issue provides a shorter horizon. Credit quality, liquidity and early-redemption terms still differ. This is a comparison panel, not a ranking of investment quality.

Read the measure: YTM is the annualised yield to maturity implied by price and scheduled payments, not the coupon or a guaranteed return. Price is expressed as a percentage of face value. Use the cursor and time axis to check observation dates; the viewer’s clock is not a last-trade timestamp.

The selection covers verifiable, embeddable issues and is not restricted to one maturity year. Matured securities belong in historical analysis, not the current comparison. Convertibles and floating-rate debt require separate treatment. These are corporate obligations, not dedicated AI bonds or an AI-sector index. CoreWeave’s displayed issue is the Reg S tranche; distribution restrictions may apply. A common currency and debt category do not make the risks identical.

The horizon of artificial intelligence: LLMs and hardware, its current pillars
Competition between accelerators expands AI’s possibilities, but capacity contracts and dependence on their tools also shape which paths can be pursued. This editorial examines GPUs, TPUs and Trainium, the influence of CUDA and competing software ecosystems, and the commitments linking model developers to cloud providers. It distinguishes announced capacity from computing resources already available, and hardware performance from the quality of reasoning obtained. It also considers an alternative research direction based on explicit knowledge and verifiable visual transformations, whose implementation and comparative costs still require demonstration. The central question is how to judge progress without allowing computing expenditure to stand in for scientific evidence.

A number with no recorded reason may end up deciding for a patient
Transparency in artificial intelligence has become a question of provenance. Yet identifying where content came from does not explain why a decision was made. This editorial examines AI-generated scientific hypotheses, expert assessments recorded as scores, and experiments showing that a model’s explanation may omit influences that changed its answer. It considers how research incentives and simplified headlines can obscure important qualifications. The concern is especially acute when decisions guide medical research and may eventually affect patients. The article argues for preserving the reasons behind judgments, so scientific conclusions remain open to scrutiny rather than becoming an archive of unexplained results.

Not yet: the third answer in machine intelligence
The most difficult thing to build into an artificial intelligence is not accuracy. It is restraint. Contemporary systems are rewarded, structurally, for producing an answer — a label, a score, a confident sentence — because a fluent reply reads as competence and a hesitation reads as failure. Yet in the places where these systems will matter most, medicine among them, the honest reply is often neither yes nor no. It is not yet. A machine that cannot say so, and instead manufactures closure to satisfy the shape of a question, is not intelligent in any sense a physician would recognise. It

External validation is not a bureaucratic detail
Systems for diagnosis, prognosis and imaging have repeatedly been deployed or promoted on the strength of performance that proved fragile under independent testing. A model that performs well in the hospital where it was born has proven only one thing: that it works at home. Consider the most instructive failure in recent clinical AI. The Epic Sepsis Model, a proprietary early-warning tool, was integrated into electronic health records across hundreds of hospitals and trusted to flag patients sliding toward sepsis. Its developer reported respectable performance. Then, in 2021, researchers at the University of Michigan did what should have happened before deployment,

A medical algorithm must not confuse cost with health
In 2019, a research team led by the physician and economist Ziad Obermeyer reverse-engineered a commercial algorithm already running quietly across the United States health system. The tool, sold by Optum, helped decide which patients — out of a population of roughly 200 million a year — would be flagged for extra medical attention. To estimate who needed that help, its designers had made a choice that looked entirely reasonable: they used each patient’s past health-care costs as a stand-in for future clinical need. Costs are measurable, structured and available at scale. The logic seemed sound. It was also, the researchers

When AI sounds certain but should say “I do not know”
In an internal review that later became public, IBM’s Watson for Oncology was shown a patient much like thousands treated every day: a 65-year-old man with lung cancer who was also suffering from severe bleeding. The system recommended bevacizumab — a drug that carries an explicit warning against use in patients with severe hemorrhage, precisely because it can cause fatal bleeding. Watson did not hesitate, did not flag the contradiction, did not signal doubt. It answered with the same fluent confidence it brought to every other case. That is the danger in its purest form: not that a system makes a
