Major financial controversy erupts over Bitcoin transaction by U.S.-listed company!
Nasdaq-listed technology company Datavault AI (DVLT) disclosed in a filing with the U.S. Securities and Exchange Commission (SEC) that a $150 million Bitcoin equity transaction had run into trouble. The company has been unable to withdraw the related BTC from third-party trading platform Biconomy since June, and has therefore decided to restate its financial statements for four reporting periods.
The news sparked investor panic. DVLT shares plunged 49.6% to $0.067 on October 27 local time, highlighting the significant risks that custody control and financial reporting can pose when companies hold crypto assets.

International credit rating agency Moody's Ratings announced on October 27 that it had assigned Ripple's U.S. dollar stablecoin $RLUSD a long-term deposit rating of “A2” and a short-term deposit rating of “P-1,” reflecting its assessment of the credit risk associated with $RLUSD’s specific redemption obligations and ability to meet them.
The ratings apply to $RLUSD, natively issued on the XRP Ledger and Ethereum by Ripple subsidiary Standard Custody & Trust Company, and do not cover the Ripple Group or the XRP token.
Jack McDonald, senior vice president of Ripple’s stablecoin business, said $RLUSD is the first stablecoin to receive an investment-grade rating from Moody’s, adding that the milestone could help boost institutional market confidence in digital assets.

In its latest review of Taiwan’s PCB and CCL (copper-clad laminate) industries, Goldman Sachs noted that Japanese suppliers of substrate materials are expanding capacity at a relatively slow pace. However, sustained growth in demand for ABF substrate materials has prompted end customers to accelerate the qualification of Taiwanese and Chinese suppliers since the first half of 2026, giving Taiwanese CCL manufacturers an opportunity to enter the high-priced, high-margin ABF substrate supply chain.
Analysts singled out Taiwan Union Technology (2383) as likely to gain market share in ABF substrate CCL from the second half of 2026. Kingboard Copper Foil (8358), meanwhile, is expected to see its newly launched ultra-thin copper foil business make a significant contribution to revenue in 2028.

U.S. Treasury Secretary Scott Bessent said at Ripple’s Swell conference on October 27 that digital assets will become an important tool for the United States to maintain its global economic influence. Dollar-backed stablecoins, in particular, could further expand the dollar’s international use.
He believes that as the global financial system becomes increasingly digital, technology infrastructure will have a greater influence on the international standing of currencies. If the United States can take a leading position in blockchain and digital finance, it will help cement the dollar’s status as the world’s reserve currency.

U.S. prediction-market platform Polymarket is once again facing regulatory scrutiny. According to an exclusive report by Reuters, the U.S. Commodity Futures Trading Commission (CFTC) is investigating whether Polymarket violated its 2022 settlement agreement by failing to effectively prevent U.S. users from accessing its offshore trading platform.
The investigation covers geolocation verification, advertising campaigns within the United States, and customer protection measures on its newly launched U.S. platform. Notably, the CFTC and the U.S. Department of Justice concluded related investigations in 2025 without bringing any charges. The renewed review of the platform’s compliance has drawn market attention.

OpenAI announces three more results spanning mathematics, computer science, and physics
On October 26, OpenAI published its latest research, claiming that its AI systems had achieved major, historic breakthroughs in mathematics, computer science, and theoretical physics.
In mathematics, OpenAI said its model proved that the “local smoothing conjecture,” proposed in 1991, holds in all dimensions. The two-dimensional case was solved in 2019 by Larry Guth, Hong Wang, and Ruixiang Zhang. The three-dimensional Kakeya conjecture was then solved in 2025 by Hong Wang and Joshua Zahl. Wang has also received the 2026 Fields Medal, the highest honor in mathematics.

BNB Chain is preparing a brand-new, high-performance blockchain. Binance founder Changpeng Zhao (CZ) described the future direction as “multiple chains, one coin.”
According to the latest technical documents published by BNB Chain, the next-generation Layer 1 (“New L1”) will operate alongside the existing BNB Smart Chain (BSC). It will not issue a separate token, but will continue to use BNB to pay transaction fees, participate in staking, and take part in on-chain governance. The development team plans to launch a testnet by the end of 2026, with a mainnet launch targeted for early 2027.

The National Basketball Association (NBA) is officially expanding its presence in prediction markets. According to an October 26 announcement, the league has named Kalshi and Polymarket its “Preferred Prediction Market Exchanges” and signed a memorandum of understanding (MOU) with the U.S. Commodity Futures Trading Commission (CFTC) to strengthen information sharing and the monitoring of suspicious trading.
The arrangement gives the two platforms access to official NBA data and the right to use NBA branding, while requiring them to comply with trading restrictions and rules against insider trading. However, because prediction markets and traditional sports betting are governed by different regulatory frameworks, the division of authority over these businesses between the U.S. federal and state governments remains disputed.

The cryptocurrency market has remained volatile recently, with Bitcoin ($BTC) falling below $80,000 several times and sparking heated debate among traders about the industry's outlook. According to CoinGecko data, Bitcoin is trading at around $80,562, up 0.8% over the past 24 hours but still down 2.8% over the past seven days. As the artificial intelligence (AI) industry continues to attract capital, cryptocurrency's growth prospects are also coming under scrutiny. Some traders believe that weakening speculative demand reflects the industry's gradual loss of appeal, while others argue that blockchain is steadily building mature business models and that future growth will depend on financial infrastructure and real-world applications.

Jeff Pu of GF Securities has published the firm’s latest VR200 outlook, forecasting that SpaceX will be the largest buyer of Nvidia Vera Rubin racks in 2027, while Foxconn (2317) will be the biggest winner in Taiwan’s supply chain. The firm rates Foxconn “Buy” and notes that Pegatron (4938) faces constraints, while Dell and Wistron (3231) face market-share pressure.

In 2027, growth will be driven mainly by VR200, as well as the initial rollout of VR300 (Ultra).

Bipartisan lawmakers and White House advisers are growing increasingly impatient with AI executives. According to an October 24 report by Axios, lawmakers and officials interviewed said this group of AI leaders is becoming “a huge political liability.” Even officials and lawmakers who support AI want them to be like CEOs in other industries: say less and focus on building their products safely.
Republican Senator Curtis: “It’s hard to imagine a group more out of touch than the AI industry.”
Axios noted that AI companies’ focus on digital consciousness and global catastrophe has turned an already complicated regulatory debate into an intractable moral panic. Lawmakers said the industry’s messaging often swings between boom and doom—sometimes invoking both at the same public event.

A major legal development has emerged in the $LIBRA meme coin controversy involving Argentine President Javier Milei. According to (Reuters), Argentine federal judge Marcelo Martínez de Giorgi ruled to end the criminal investigation into Milei and 10 other people connected to the case, finding that the available evidence was insufficient to prove criminal fraud. The ruling covers Milei’s sister, Karina Milei, the secretary-general of the Office of the President, as well as Hayden Davis, an adviser to the LIBRA project, among others. However, the case could still be appealed, and some investors continue to seek legal recourse.
Milei publicly endorsed $LIBRA; its price plunged 95%, prompting an investigation

Changpeng Zhao (CZ), founder of global cryptocurrency exchange Binance, appeared at the Nasdaq bell-ringing ceremony in the United States on October 26, joining the management team of publicly listed BNB Standard Corporation to celebrate the company’s transformation. Formerly known as CEA Industries, the company officially changed its name to BNB Standard on September 29, while keeping its stock ticker, BNC.
