More →OpenAI's valuation was cut by $150 billion, and the AI boom faces challenges.
According to a report by Bijie, OpenAI has reportedly lowered its valuation from the previously discussed $1.4 trillion to $1.25 trillion, a reduction of $150 billion, due to investor concerns over rapidly growing AI spending. Although the adjusted valuation is still higher than the company's previous financing valuation, the change indicates that investors have become more cautious about the massive investment in AI development. OpenAI is currently seeking an additional $30 billion in financing to support its ambitious expansion plans. Meanwhile, OpenAI is also facing resistance from investors over its earlier $1.4 trillion valuation target. Nevertheless, the adjusted valuation is still about 47% higher than OpenAI's $852 billion financing valuation set in March 2026.

Claude wrote 180 million lines of mathematical proofs for 123 open-source libraries, finding hundreds of bugs.
According to CoinWorld news, in collaboration with formal verification company Theorem, Claude wrote approximately 180 million lines of mathematical proofs for 123 open-source libraries, successfully identifying hundreds of software vulnerabilities. Traditional testing relies on random data input and cannot guarantee that no errors are missed, whereas through mathematical proofs, Claude attempted to fundamentally eliminate specific types of errors. Within a few weeks, Claude completed verification of 239 test entry points, and the results showed that under the specified operating environment, these programs would not trigger crashes when faced with arbitrary inputs smaller than 64 MB. During the proof process, Claude also discovered and fixed hundreds of bugs, including out-of-bounds memory writes and image decoding vulnerabilities. In the past, this type of mathematical verification was extremely time-consuming; for example, the mathematical verification of the seL4 operating system kernel took about 20 years.
GF Securities' Guo Lei: Policy support for the stable and healthy development of the capital market has a clear goal.
According to a report from Bijie.com, Guo Lei, chief economist at GF Securities, said in an interview on October 23 that, judging from a series of policy signals released by multiple departments at the 2026 Financial Street Forum annual meeting, the goal of policy support for achieving the full-year economic targets and for the stable and healthy development of the capital market is clear. He believes that since the end of the third quarter, broad fiscal funds such as special bonds and policy-based financial instruments have been implemented in a concentrated manner. Looking at the September economic data, infrastructure investment and manufacturing investment are already in the process of initial recovery. The October EPMI data exceeded seasonal patterns, indicating that economic improvement is continuing.

Bitcoin is in "wait-and-see mode," and that could be a good thing.
CoinWorld data: Bitcoin is currently priced at approximately $81,735, with volatility not exceeding 6% over the past month and a daily decline of 1.2%. Analysts note that the market overall has been relatively calm, with none of the top five cryptocurrencies exceeding 2% volatility over the past week, and the Fear and Greed Index sitting at a neutral 47. Jake Koch-Gallup of Blockworks said that a calm market may signal the arrival of a bull market, as similar low-volatility periods in the past have typically led to 30% price swings. André Dragosch of Bitwise Europe believes the current calm period is a "constructive signal," with prolonged flat trading often accompanied by a few sharp moves. Carlos Guzman of GSR attributes the market's dullness to "risk-off" sentiment in global markets. Three catalysts lie ahead in the next two weeks: the Federal Reserve's interest rate decision on October 28, $11.69 billion in Bitcoin options expiring on October 30, and the U.S. midterm elections on November 3 — events that could determine the crypto market's next major move.
Japan's inflation exceeds the central bank's 2% target for the first time.
Japan's inflation rate has risen back above the Bank of Japan's (BOJ) 2% target for the first time this year, with core inflation climbing to 2.1% in September from 1.7% in August. This marks the first time it has exceeded the target since December last year. Notably, Japan experienced 15 years of sustained deflation from the late 1990s. Between 2022 and 2025, annual headline inflation exceeded 2%, the longest such stretch since 1982. Higher fuel costs, a weak yen, and strong AI demand are driving prices higher. The BOJ has raised interest rates by 50 basis points this year to 1.25%, a 31-year high. The market expects one more rate hike before the end of the year.
