OpenAI announces that AI has achieved three scientific breakthroughs, covering mathematical conjectures, computer algorithms, and the Millennium Prize Problems.

Overnight to early this morning, Anthropic filed for an IPO, reigniting short-term AI hype in the market. The Philadelphia Semiconductor Index rose around 3% in a single day, driving the S&P 500 up 0.70% and the Nasdaq up 0.82%, both ending their two-day losing streak. On the other hand, ahead of the Federal Reserve's policy decision, the U.S. Treasury market remained calm. Oil prices edged lower, but Middle East risk premiums persisted. Additionally, market turmoil in Brazil has drawn global attention. With Lula's surprise election victory, Brazil's stock market, bonds, and the real all slumped simultaneously; multiple stocks dropped over 30% in a single session, with some falling more than 50%. Investors worry the new government will expand fiscal spending, stoking inflation expectations, leading to a sharp spike in Brazil's 5-year credit default swap (CDS) spreads. For equities, per data from BIT Stock Platform, star stock Nvidia rose 2.4%, Micron gained 2.98%. CoreWeave reversed its pre-market decline to close up 1.76%. The optical communications sector stayed strong: LITE rose over 8%, AAOI over 6%. Neocloud, which was bearish on by Musk, showed relative resilience; only NBIS fell 3.48%, while other major stocks closed higher. The storage sector was flat: SNDK rose 1.42%. Crypto-related stocks fell broadly: MSTR dropped 4.21%, the previously standout NEAR Treasury Company fell 10.48%, BMNR down 6.52%, CRCL down 7.07%.

According to a report by The New York Times on the evening of the 26th Beijing time, as widespread concerns mount that the U.S. and Israel may soon launch a new round of strikes against Iran, senior representatives from Saudi Arabia, Turkey and Pakistan held talks with Iranian officials in Tehran on Monday. The visit is the latest step in a series of intense diplomatic efforts by regional mediators in recent times. Gulf officials said Monday’s talks aim to support the mediation work of Qatar and Pakistan, with the goal of urging Iran to demonstrate sufficient flexibility to reach a diplomatic solution with the U.S. Two diplomats noted that Qatari mediators have been pushing for a U.S.-Iran agreement under which both sides will make a series of concessions within five days. Under part of the proposed concession terms, Iran will reopen the Strait of Hormuz to allow commercial vessels to transit, while the U.S. will lift its naval blockade on Iranian ports. The main obstacle to reaching an agreement is determining the timing of each side’s respective concessions. They added that mediators have been pressing Iran to make concessions on its nuclear program in the early phase of the agreement’s implementation.

Intel has announced the acquisition of Israeli quantum computing startup Classiq, with the transaction expected to be completed in the first half of 2027. The deal will integrate Classiq’s quantum algorithm software platform with Intel’s silicon-based qubit hardware capabilities to build a full-stack quantum computing business spanning both hardware and software, filling Intel’s gap in quantum software. CEO Chen Liwu stated that the merger will transform Intel’s quantum computing division into a "full-stack quantum computing business".

U.S. President Donald Trump stated, "In my view, the Brazilian election is very bad—it looks like another rigged election." Earlier news reported that Luiz Inácio Lula da Silva unexpectedly won Brazil’s presidential election, triggering a sharp repricing of Brazilian assets: the benchmark stock index plummeted by double digits, the local currency real recorded its largest decline since the start of the 21st century, and the market’s deep-seated concerns over fiscal discipline and state-owned enterprise governance flared up.

According to BIT (Bit.com) market data, Apple’s U.S. stock is currently down 1.02%, with its market capitalization temporarily standing at $5.02 trillion. Apple stated in a post that it has noticed internal screen defects on a small number of iPhone Duo units, advising users to contact AppleCare for a replacement. Apple’s first foldable iPhone, the iPhone Duo, has seen consecutive screen damage issues near the hinge since its launch in major markets on October 23. Photos uploaded by users show that some devices have white, ray-like cracks starting from the hinge center and extending to the lower right of the screen. Industry insiders believe the defects, concentrated at the same hinge location, may be related to hinge design, and Apple may have to redesign the relevant structure. Reports indicate Apple faced hinge supply issues during the R&D phase. Its original primary supplier, U.S.-based Amphenol, was replaced by Taiwan’s Xinrixing due to lower-than-expected production yield, but the latter also encountered manufacturing difficulties and had to supply only "golden samples" that met standards. Apple previously stated the iPhone Duo’s hinge includes over 100 components and uses a 3D-printed hinge module. Since the product has entered mass production, Apple may need to resolve the defects by reducing hinge components and other methods while minimizing design changes. Reports note the hinge issues could impact product delivery and sales performance. Apple’s expected supply to suppliers shows that as of the end of this year, the component supply corresponding to the iPhone Duo’s full production capacity is about 6 million units. According to another report, component supplier Fine M-Tec has stated that recent quality issues with related products are unrelated to the assembly of its supplied components.

According to CryptoQuant data, stablecoin reserves held by Binance and Binance.US account for approximately 75% of the total stablecoin reserves of monitored cryptocurrency trading platforms, with the remaining platforms collectively making up the other 25%. This ratio stood at around 58% in mid-2025, and rose to nearly 75% by October 2026. The data indicates that stablecoin reserves are further concentrating on Binance, meaning its influence on crypto market liquidity is continuing to expand. Stablecoins can serve as potential trading funds, providing purchasing power for crypto assets such as Bitcoin, but an increase in reserve size does not necessarily signal an imminent entry of buy orders. Additionally, the rise in Binance’s stablecoin reserve share may stem from declines in other trading platforms’ reserves rather than net capital inflows. Therefore, subsequent analysis will still need to combine total stablecoin volume and capital flows to determine whether this will translate into new demand for the crypto market.
