Research institution Tiger Research researcher Ryan Yoon released the final report of the prediction market series, discussing whether prediction markets have practical utility. The report states that participants bear the judgment results with funds, and prices are updated in real-time with new information, forming probability distributions comparable to traditional polls, expert surveys, and economic forecasts; prediction markets have expanded from sports and election predictions to macroeconomic and geopolitical data infrastructure.The report lists that Google Finance, CNBC, CNN, and The Wall Street Journal have displayed prediction market probabilities, and the parent company of the New York Stock Exchange, Intercontinental Exchange, along with the electronic bond trading platform Tradeweb, distributes relevant data to institutional clients. A working paper from the Federal Reserve Board describes the prediction market Kalshi as a high-frequency, continuously updated benchmark with rich information distribution. The paper states that Kalshi's median and mode predictions for the federal funds rate recorded perfectly the day before the FOMC meeting and significantly outperformed federal funds futures during that period; compared to Bloomberg consensus, it is more accurate for overall CPI and statistically similar for core CPI and unemployment rate.The report also cites research from the Iowa Electronic Markets: in five U.S. presidential elections from 1988 to 2004, and in a comparison of 964 polls, it was more accurate in 74% of cases; the average voting share error one week before the election was 1.5 percentage points, lower than Gallup's final poll of 2.1 percentage points. The report suggests that the platform needs to deepen liquidity to resist manipulation, communicate with regulatory agencies, and position itself as a monitoring tool while maintaining open transparency and data supported by independent research.

The U.S. Department of Commerce will allocate up to $389 million to support chip research and development.

According to CoinDesk, Ben Edgington, the coordinator of the Ethereum rapid finality research direction, along with several researchers, submitted a draft proposing to reduce the transaction finality waiting time from about 16 minutes to about 4 minutes, improving it by approximately four times.The current goal is to push this draft into the formal upgrade proposal process. The core idea of the draft is to separate the original "block selection" and "finality confirmation" mechanisms of validators, allowing finality to progress at a faster pace and facilitating future adoption of quantum-resistant signatures.Faster finality is expected to reduce the costs incurred by cross-chain transfer services due to capital occupation. The Ethereum Foundation's research provides an example: if a service advances about 1 million dollars per hour, under a 16-minute delay, approximately 267,000 dollars would be pending recovery, which could be reduced to about 67,000 dollars after shortening to 4 minutes.

According to "Reading Plus," the short drama application Hongguo Short Drama App, owned by ByteDance, has launched "Xiaoguo AI." This feature has undergone a period of gray testing and is now officially online, relying on the Doubao large model. It is labeled as Hongguo AI BOT within the app and is positioned as an AI assistant for finding short dramas, providing series search and recommendations. The report states that this is the first time Hongguo has integrated conversational AI into the user-end drama search scenario, beyond AI short drama production.According to practical tests by "Reading Plus," the main entry point is located in the app's search bar. Clicking it leads to the conversation page, and users can also ask questions in the comment section by @XiaoguoAI. The page features quick questions, such as "What short dramas are everyone watching?" and "What are the differences between male-oriented and female-oriented short dramas?" When users input keywords, it returns a list of suggestions, a trending short drama list, and series popularity. The AI responses can pop up short drama cards with play buttons, which redirect to the viewing page when clicked.This tool relies on generative models and search plugins to return information such as titles, plot summaries, poster stills, reputation ratings, and playback channels based on keywords and viewing preferences. From user feedback, it can also record update requests and push notifications when new seasons of followed series are available for reservation.

U.S. President Trump will emphasize his administration's actions against overseas cryptocurrency fraud at a cybercrime prevention event at the White House on Wednesday. According to Reuters citing White House officials, these overseas criminal networks lure Americans into participating in fraudulent cryptocurrency investments. Trump and cabinet members plan to point out that the government has shut down multiple fraudulent cryptocurrency investment websites and is working to close down online impersonation scams. Secretary of Homeland Security Markwayne Mullin, FBI Director Kash Patel, Secretary of Defense Pete Hegseth, and Attorney General Todd Blanche are expected to attend.The event follows an executive order from March this year, where Trump instructed the Department of Justice to prioritize identifying and prosecuting cyber fraudsters, followed by a memorandum requiring the Department of Homeland Security to collaborate with private companies to monitor foreign criminal hacker organizations. FBI data shows that in 2025, over 1 million cyber fraud complaints were submitted by the American public, a 17% increase from 2024, with record losses. Cryptocurrency fraud accounted for more than half of the losses, with the FBI's Internet Crime Complaint Center recording 181,565 cryptocurrency-related complaints, resulting in losses of $11.366 billion, with cryptocurrency investment fraud causing $7.2 billion in losses.Most of the fraud activities trace back to organized crime groups in Southeast Asia, involving Cambodia, Laos, and Myanmar, where criminals exploit trafficking victims as forced labor in scam operations. Americans aged 60 and above bear the heaviest losses, with cryptocurrency-related losses reaching $4.43 billion. Cryptocurrency ATM fraud caused losses of $389 million, a 58% increase from 2024; secondary scams targeting previous victims caused an additional $1.4 billion in losses. The FBI's "Operation Upgrade" notified 3,780 victims suffering from cryptocurrency investment fraud in 2025, estimated to recover $225.8 million.

According to CoinPost, Japan's Minister of Land, Infrastructure, Transport and Tourism, Toshiaki Inoue, stated in the House of Representatives' Land, Infrastructure, Transport and Tourism Committee that he will study the introduction of stablecoins into the consumption tax exemption system for foreign tourists visiting Japan, and mentioned a "refund method" for tax refunds after departure confirmation, stating that he will promote responses from the user's perspective.According to the Japan Tourism Agency, the country's tax exemption system will change to a refund method starting from purchases made on November 1: Tourists will purchase goods at tax-included prices, and within 90 days from the date of purchase, upon departure confirmation by customs, they can then receive the consumption tax refund, which will be handled by the duty-free shop or an entrusted refund agency.

Seventeen-year-old Kimi former researcher Chen Guangyu has been reported to join Discovery Loop, an AI company founded by former Google chief scientist Jeff Dean. On October 20, the anonymous account Arfur Grok, which tracks the movement of AI talent in Silicon Valley, disclosed this news. Chen Guangyu had just announced his departure from Kimi five days prior, where he was involved in research on Attention Residuals architecture and the development of Kimi K3.Discovery Loop was established in August of this year, co-founded by Jeff Dean and three other Google veterans. The company plans to enable AI to autonomously propose research hypotheses, run thousands of experiments in parallel, and adjust plans based on results, initially focusing on AI model development, with future expansion into fields such as healthcare, materials, and energy. Google's parent company Alphabet is one of its founding investors, and the company has yet to launch any public products. Business Insider reported in September that Discovery Loop is seeking funding at a valuation of about $50 billion.Previously, Silicon Valley investor Deedy Das mentioned a 17-year-old who received five job offers in the million-dollar range in AI. There was speculation that it was Chen Guangyu, but Deedy never publicly disclosed the individual's identity.

On October 20, 2026, Jason Pagoulatos, a macro and market author at the cryptocurrency research institution Delphi Digital, released a report titled "The House Always Wins: Why Speculation is the Theme of This Decade." Pagoulatos stated that speculation has two long-term engines: constructive and lottery-like. Technological changes open the former, while fiscal and political pressures open the latter; historically, many famous bubbles have been driven by one or the other. Today, both are operating at high speed simultaneously, and the same batch of technologies is feeding both. He thus considers speculation itself as an investable theme, advocating for holding places for liquidation bets rather than holding the bets themselves.The data cited in the report includes that the U.S. federal deficit for fiscal year 2025 is $1.8 trillion, about 5.8% of GDP, with net interest around $1 trillion per year, exceeding defense spending. The Harvard Joint Center for Housing Studies states that the national median price for single-family homes in 2024 is 5.0 times the median household income; the National Association of Realtors reports that first-time homebuyers account for 21% of transactions, with a median age of 40. According to the American Gaming Association, legal sports betting amounts have risen from $6.6 billion in 2018 to $166.9 billion in 2025. Capital expenditures for Microsoft, Alphabet, Amazon, and Meta are approximately $416 billion for 2025, with guidance for 2026 totaling about $720 billion to $745 billion, plus Oracle.In terms of venues, Robinhood's event contract revenue for Q2 2026 is $156 million, higher than stock revenue of $129 million and crypto revenue of $100 million during the same period. Hyperliquid's expenses for 2025 are about $972 million, with transactions around $3 trillion. Kalshi reportedly raised funds at a valuation of about $40 billion, and Polymarket is set to relaunch in the U.S. by the end of 2025. The author also mentions that the most likely mistake is to hold inventory of the crowd and call it a casino. The report states that it is for educational and general informational purposes only and is not investment advice; the author may hold Bitcoin, HYPE, HOOD, and LIT, and affiliated party Delphi Ventures may invest in the assets or agreements discussed in the report.

According to a report by the Financial Associated Press, 2022 Fields Medal winner Hugo Duminil-Copin stated at the French Mathematical Society that his original research direction no longer exists. He said, "On Tuesday night, I cried, and my crying woke up my daughter. They (OpenAI) have destroyed my field of research." The report mentioned that at least 16 papers related to his long-term research interests were included in the results released by OpenAI earlier this month.The report noted that since April of this year, AI companies have frequently announced solutions to unsolved mathematical problems to showcase their model capabilities. Earlier this month, OpenAI released over 700 papers at once, claiming to have solved hundreds of previously unresolved mathematical problems. Stephane Mallat, a recipient of the 2025 Gold Medal from the French National Center for Scientific Research, stated that the emotional impact of AI achievements is significant, but society still needs mathematicians and opposes the notion that "mathematicians are no longer needed." Cedric Villani, the 2010 Fields Medal winner, remarked that in mathematics, the process of reaching conclusions is far more important than the conclusions themselves.Francois Charles, head of the mathematics department at the École Normale Supérieure in Paris, stated that AI is changing the pathways for young people entering the mathematics field and pursuing PhDs, and concerns about talent development and career progression are valid; regarding the research itself, he believes that AI may help solve problems that were previously difficult to tackle. The Simons Foundation announced last week a $15 million initiative to help mathematicians cope with the changes brought by AI, with funding contributed by OpenAI and Anthropic, aimed at supporting workshops to evaluate AI achievements and establish standards for AI usage.

On October 20, researcher 100y from the cryptocurrency research institution Four Pillars published a response to external doubts: Robinhood Chain has not disappeared, its ecosystem remains resilient, and it is preparing for the next round of growth. The chain is set to launch on July 1, 2026, positioning itself as an on-chain financial network centered around tokenized stocks. The article states that Robinhood's cryptocurrency business revenue share dropped from 27.2% in the first quarter of 2025 to 12.6% in the first quarter of 2026.According to data from The Rollup, the chain's daily network fees on September 4 were approximately $8.27 million, compared to Robinhood's total cryptocurrency business revenue of about $100 million in the second quarter of 2026. After the market weakened and meme popularity cooled, fees fell by over 99% from their peak, with daily fees in mid-October around $30,000 to $40,000, less than 1% of the peak. 100y attributed the spike in fees to congestion in September: the chain uses the Arbitrum tech stack, and the base fee index rises when usage exceeds target processing capacity.As of the publication date, the on-chain Total Value Locked (TVL) is approximately $1.1 billion. The Steakhouse Financial curation and the Steakhouse USDG Vault supplying USDG to Morpho account for about half of this, with a scale of approximately $540 million and still rising, and around 75,000 deposit wallets. Stocks and ETFs account for more than half of the issued Real World Asset (RWA) tokens, with an associated outstanding value of about $150 million. The spot trading volumes on September 4 and October 7 were approximately $3.27 billion and $3.24 billion, respectively, and daily trading volumes have remained at least around $600 million to $700 million since then. Robinhood has strategically invested in the perpetual platform Lighter and Arcus. 100y stated that the next round of growth depends on the scale of the treasury and stock tokens, meme trading, perpetual activities after the points period, as well as more builders and new on-chain financial primitives.

Grayscale Research Director Zach Pandl stated in "The Stack" published on October 20, 2026: AI computing infrastructure stocks have recently declined due to investors' concerns about rising borrowing costs, while the financing needs of related companies are high. The stock index, which includes AI cloud service providers CoreWeave and Nebius, has fallen by approximately 27% since the end of September, according to data from Bloomberg and Grayscale Investments, based on the Indxx High-Performance Computing Index, as of October 19, 2026.Pandl noted: Most of these companies are in early stages and capital-intensive, with some neocloud capital expenditures being several times their current revenue. The top five holdings in the index have a capital expenditure to sales ratio exceeding 230% over the past 12 months, with data as of October 19, 2026. He believes that while stock prices are correcting, the demand and prices for computing power remain stable, with demand for computing power increasing rather than decreasing.He also anticipates: The decline in token prices and the increase in AI agent usage will lead to higher inference demand, thereby supporting the growth of computing power demand; if demand increases and computing power prices remain high, these companies may benefit. He also mentioned the slowdown in GPU depreciation, as well as the overlap between AI computing power and the Bitcoin mining industry, with the possibility of rising Bitcoin prices. Pandl believes: Higher borrowing costs have suppressed computing infrastructure stocks, but the fundamental trend of rising computing power demand remains valid, and this correction should be seen as an opportunity to increase exposure to the energized compute layer.
