Asian stocks saw a sharp correction at the open today (7/28) after the U.S. stock market’s Philadelphia Semiconductor Index fell and concerns about AI-related capital expenditures resurfaced. Taiwan stocks plunged more than 1,700 points in the morning session, breaking below the 42,000-point level outright. Markets in Japan and South Korea also dropped in tandem; the South Korean market (KOSPI) even triggered the circuit breaker mechanism again during the day, halting trading for 20 minutes.
Taiwan stocks plunge by more than 1,000 points; TSMC slips below its quarterly moving average
Taiwan stocks opened to a barrage of selloffs today, with the intraday low reaching 41,830.09 points. Leading heavyweight TSMC fell 80 yuan in the early session (down 3.4%) to 2,270 yuan, breaking below its quarterly moving average again (2,347 yuan). In the memory sector, Winbond and Nanya Technologies also saw even deeper declines at one point, hitting the daily limit down.

The Senate seeks a preliminary vote, but getting it through before the recess remains difficult
The U.S. cryptocurrency market structure bill, the CLARITY Act, is again entering a crucial week of political back-and-forth in Washington. The latest reports indicate that the Senate still expects to schedule a preliminary vote before the summer recess on August 7, to test whether there is sufficient political momentum to move the bill forward to full Senate consideration. However, many observers believe that without a cross-party time agreement and adequate procedural coordination, the odds of getting the entire bill passed before the recess remain low.
The biggest challenge right now comes from limited procedural time and the 60-vote threshold. Even if a motion to end debate is filed this week, the earliest a preliminary procedural vote could take place would be a few days later. Further steps would still be required, including debate, amendments, and the final vote. Democrats, including lawmakers such as Elizabeth Warren and Chris Murphy, continue to have concerns about the bill’s contents. Within the Republican Party, disputes over the ethics provisions have also not been fully resolved. As a result, the CLARITY Act in the short term looks more like a stress test of political pressure than a near-term legislative breakthrough.

Bitcoin falls back below $64,000; a rebound in the short term meets resistance
Earlier, as the U.S.-Iran military standoff eased temporarily and the price of crude oil pulled back, Bitcoin ($BTC) briefly regained the $65,000 level, with market risk appetite recovering for a short period. However, as of the latest quote, Bitcoin’s price has retreated to $63,557, falling below the $64,000 psychological mark. This suggests that the rebound momentum from yesterday was unable to sustain, and that short-term bulls and bears have once again entered a standoff.

The key to this round of volatility lies in how quickly macro factors change. After the U.S. and Iran paused attacks on each other, WTI crude oil futures briefly dropped by about 5%, and Brent crude also fell noticeably. The market initially took this as a sign that inflation pressures were easing. However, crude oil had broken above $100 in the prior week, which has already heightened the market’s sensitivity to inflation and interest rates. Even if energy prices cool off in the short term, investors still don’t dare to chase prices aggressively.

The EU expands sanctions on Russia, adding 14 crypto platforms and 94 financial institutions
According to a Reuters report, on July 23 the European Union adopted its 21st round of sanctions against Russia, naming finance, energy, the military-industrial sector, and networks for sanctions evasion as the main targets. The latest measures add 218 individuals and entities to the list, including 48 individuals and 170 entities—one of the largest single additions by the EU in nearly four years.
EU High Representative for Foreign Affairs and Security Policy Kaja Kallas said the latest sanctions target more than 100 banks and crypto businesses, while also cracking down on Russia’s shadow fleet, refineries, and the military supply chain.

On July 24, 2026, SpaceX successfully carried out the 13th test flight mission of Starship (Starship Flight 13), achieving multiple key engineering milestones. This mission not only saw the successful return and ocean splashdown of the Super Heavy booster in the Gulf of Mexico, but also, for the first time during the space stage, successfully deployed 20 Starlink V3 satellites. After deployment into the orbit, the satellites completed solar array deployment and laser link tests while in the suborbital orbit. They also used the onboard camera to photograph the Starship heat shield from outside, providing brand-new data for rocket diagnostics.
Although the satellites were scheduled to burn up during reentry into the atmosphere 20 minutes later, the new-generation communications and orbital computation technologies had already been fully validated. The successful completion of this test flight marks an important milestone as the era of large-scale satellite deployment and space-based cloud computing moves forward.

Daily NK: Two major North Korean banking systems were infiltrated by a former military hacker from within the country
According to a report by Daily NK (run by defectors from North Korea), a criminal group made up of retired military hackers was recently discovered to have infiltrated the internal network systems of the North Korean Central Bank and the trading bank.
The hacker group converted the stolen national trading funds into cryptocurrency, and carried out large-scale smuggling of foreign currency in border areas. The National Intelligence Service of North Korea (formerly the Ministry of State Security) arrested and rounded up the group on July 12.
The Bank of Korea (North Korea) is responsible for issuing the nation’s currency and managing treasury funds, while the trading banks handle overseas payments and foreign-exchange transactions. Both are core units of North Korea’s financial system. This time, they were breached by an insider, shocking the Pyongyang authorities.

Keigo Higashino dies; colorectal cancer took the life of a generation of mystery novelist
Earlier today (7/27), the official account said that Japanese renowned mystery novelist Keigo Higashino passed away on July 23 due to colorectal cancer. He was 68 years old. His family has handled his arrangements through a family-only funeral.
Keigo Higashino, born in 1958 in Osaka, made his debut in 1985 with the mystery novel (After School) that won the Edogawa Rampo Award. He subsequently released the first installment of the “Detective Galileo” series, shaping the character of the genius physicist Manabu Yukawa—beloved for using his professional knowledge to solve mysteries. Among his most representative works, (The Devotion of Suspect X), published in 2005, won the Naoki Prize and the Honkaku Mystery Award, becoming one of his signature achievements.

As the Robinhood Chain draws a large influx of capital and meme-coin speculation continues to heat up, Robinhood CEO Vlad Tenev’s X account was reportedly hacked on Thursday. The compromised account was then used to post fake meme-coin promotional tweets in an attempt to mislead investors.
Robinhood subsequently confirmed that the Vlad Tenev account had been compromised and said it had deleted the related posts. The company added that it is working with the X platform to restore control of the account.
Fake official meme coin claims it will be listed on Robinhood
Tweets posted by the hijacked account introduced a token called Vladhood ($VLAD), claiming it is the “official mascot of the Robinhood Chain,” and asserting that the token will be listed for trading on the Robinhood App in the future.

Kiyosaki again issued a warning: U.S. debt is approaching $40 trillion
(Rich Dad Poor Dad) Author Robert Kiyosaki once again warned about the U.S. dollar and U.S. fiscal risks. In a recent post on the X platform, he said that U.S. public debt has nearly reached $39 trillion, and compared the current debt level with the period before the 2008 global financial crisis. At that time, U.S. public debt was about $9.5 trillion; today it has grown more than fourfold. The speed of debt expansion makes him believe the purchasing power of the dollar is facing greater pressure.
According to market-tracking data, U.S. public debt as of July 22 had reached approximately $39.64 trillion—only one step away from the $40 trillion mark.

China’s leading semiconductor memory chip maker ChangXin Storage (CXMT) was officially listed on the Shanghai Stock Exchange today (7/27). Its share price surged 472% on the first day, making it the largest listed enterprise of its kind in China. Through this initial public offering (IPO), the company raised RMB 66.6 billion (about $9.8 billion), setting a record for the second-largest IPO in China’s history, behind the Agricultural Bank of China in 2010.
Against the backdrop of strong demand for AI chips and China’s push for technological self-reliance, ChangXin Storage’s powerful debut not only reflects the market’s enthusiastic pursuit of the memory chip story, but also serves as an important benchmark for Beijing’s efforts to reduce reliance on foreign suppliers. Despite recent volatility in the semiconductor sector, analysts and institutional investors generally remain optimistic about its long-term growth potential.

NVIDIA invests US$1 billion in Naver to build AI data centers together
During the AI Summit in San Francisco, NVIDIA officially announced an investment of US$1.01 billion, subscribing to a third-party placement of newly issued shares by South Korean internet giant Naver. This gives NVIDIA about 4.5% equity and elevates it to become the company’s third-largest shareholder. Benefiting from this, Naver’s shares surged close to 10% at today’s (7/27) market close.
Both parties have teamed up with global asset management giant Brookfield to launch a large-scale expansion plan for South Korea’s “GAK Sejong” AI data center, with an expected investment of up to US$9 billion. The three parties will jointly build a sovereign AI cloud infrastructure capable of gigawatt (GW)-scale capacity, with services covering both South Korea and the United States.

Schiff questions STRC buying pressure; retail exits spark controversy
Gold supporters and long-term Bitcoin critics Peter Schiff have recently launched another attack, aiming at Strategy’s STRC preferred shares and the company’s capital model. The incident began after Strategy CEO Phong Le posted the latest STRC holder distribution on the X platform, noting that from March to July, the proportion of retail holders of STRC fell from 78% to 71%, while institutional investors’ participation kept rising. The average institutional holding size increased by 105%, reaching about $3.5 million.
Interpret these data as institutions adopting acceleration, and say that “the institution is stepping in.”

As BitMEX announced it was ending operations, the exchange and its founders were again hit by legal trouble. According to a report by Benzinga, a class-action lawsuit was filed on July 23 in the U.S. District Court for the Southern District of New York, alleging that BitMEX secretly operated an “insider trading desk” that directly bet against its own customers.
Allegations that BitMEX set up an “insider trading desk” to take bets against customers

Korean semiconductor giant SK Group has recently landed a major deal and formally signed a strategic cooperation memorandum (MOU) with NVIDIA. The comprehensive AI collaboration is set to reach a total scale of up to 500 billion US dollars, covering next-generation memory supply and the construction of large AI factories.
However, this much-anticipated positive development on a global scale failed to lift the Korean stock market. On the 27th, the KOSPI index staged a “good news that has already been priced in” scenario, and SK hynix’s shares in South Korea still fell by nearly 1% after the market opened.
SK hynix and NVIDIA join forces in a major partnership, securing HBM4 memory supply
Based on the cooperation details announced by both parties, SK Telecom will build a large AI cloud center in South Korea with a power capacity of 2GW, introduce NVIDIA's DSX architecture, and adopt the Vera Rubin computing system equipped with SK hynix HBM4 memory. The first AI factory is expected to go into operation in 2027.

The U.S.-Iran airstrike is called off, but Taiwan stocks still fall at the open
The U.S. has paused airstrikes on Iran for two consecutive days, driving a rebound in U.S. stock index futures. However, affected by last week’s sharp sell-off in U.S. semiconductor stocks, Taiwan’s stock market still opened lower today (7/27). In the morning session, it once fell by more than 500 points and slipped below the 43,200 level.
With the earnings reports of major U.S.-Taiwan tech giants rolling out one after another this week, along with the Fed’s upcoming interest-rate decision meeting and the implementation of the latest U.S. tariff provisions under Section 301, market sentiment has turned quite cautious.

BitMart initiates its exit timetable: trading stops on August 26
Cryptocurrency exchange BitMart issued an unexpected announcement on July 26, stating that it will gradually cease platform operations. Starting at 9:30 a.m. on the same day, it will progressively stop new user registrations, deposits of digital assets and fiat currencies, and simultaneously restrict opening positions for contracts as well as placing new spot orders.

Requests submitted after the deadline will be moved to a specialized handling process, and some withdrawals may also take longer due to compliance requirements such as identity verification, on-chain risks, source of funds, sanctions lists, or Travel Rule.

Bitcoin recovers $65,000; short-term buying pressure retests the resistance area
After a quiet weekend session, Bitcoin ($BTC) regained above $65,000 during intraday trading on July 27. The price briefly rose to $65,504, then fell back to around $65,100 and fluctuated. This indicates that $65,000 is no longer just a lower line of defense, but has once again become the immediate battleground between bulls and bears. If the price can hold above this range, the market will have a better chance to treat the level that broke down on July 24 as a short-term false breakdown, and to once again watch the $68,000 resistance zone.

Generative AI has already become a writing tool for many creators, but readers are finding it increasingly hard to tell whether an article was written by a human or whether most of its content was completed by AI.
To address this, email newsletter platform Substack announced the launch of a new AI detection feature, directly countering the “Claudefishing” phenomenon the company describes, with the goal of helping readers understand what proportion of the content they’re reading comes from AI.
What is Claudefishing?
The term “Claudefishing” comes from Anthropic’s AI model Claude. The concept is similar to catfishing online, which involves impersonating someone’s identity.

After SpaceX completed its first public offering (IPO) in mid-June, its stock price faced a significant correction. Yesterday (7/25), SPCX closed at $115.07, down 15% from its offering price.
Morgan Stanley reports that the current level of SpaceX’s stock price reflects investors giving its artificial intelligence (xAI) business an extremely low valuation. At the same time, Tesla’s stock also fell sharply this week by 18% because its Q2 earnings missed expectations, and large investments in emerging projects turned cash flow negative.
The prices of its two major companies were both downgraded, causing CEO Elon Musk’s net worth to shrink by about $130 billion in a single week. Although the market is taking a wait-and-see stance in the short term toward technology firms with high capital expenditures, most Wall Street investment banks still maintain long-term bullish views on SpaceX. A Morgan Stanley analyst also reiterated its $300 price target, saying that a stock-price correction has presented a long-term opportunity to buy.
