According to a 46-page report from financial investment data company PitchBook, the market platform Kalshi has a baseline scenario valuation of approximately $30.4 billion, a peak valuation of about $42.1 billion during strong market performance, and a pessimistic scenario of $22.8 billion. Kalshi completed a $1 billion Series F financing in May this year, with a post-money valuation of $22 billion.PitchBook expects Kalshi's revenue to reach $6.4 billion by 2030, with adjusted profits reaching $3.7 billion, and believes that partnerships with platforms and market makers such as Robinhood and Susquehanna will help consolidate market share. The report lists the regulatory risks of the sports prediction market as a key variable affecting valuation, with data showing that the sports market currently contributes about 69.9% of Kalshi's event fee revenue; if Exotics products such as multi-event combinations are included, the proportion rises to 82.4%.Several states in the U.S. and Native American tribes are suing over the legality of Kalshi's sports prediction products, and related cases have created discrepancies between federal appellate courts, with the Supreme Court expected to intervene next year. PitchBook believes that even if the final ruling is unfavorable to Kalshi, the company may still adjust its business model through state-level licensing and the development of non-sports prediction products, but a significant decline in sports revenue will still notably impact its growth expectations.

According to Cointelegraph, the European Securities and Markets Authority (ESMA) will establish a new EU strategic regulatory priority themed around digital innovation starting in 2027, initially focusing on AI and tokenization.Regulatory authorities in EU member states will identify emerging areas of tokenization, documenting how businesses use or plan to use AI and tokenization technologies in products and processes that directly affect investors, and conducting preliminary checks on some of the most affected companies.ESMA stated that the risks that need to be prioritized include biased or misleading AI outputs, products that are difficult for investors to understand, and reliance on a few third-party service providers. This priority will be advanced in parallel with the regulatory priority for cyber and operational resilience that will be launched in 2025.

Coinbase Chief Cryptographer Yehuda Lindell stated on the MARA Foundation TV program that the exchange is designing a custody system capable of adapting to any post-quantum signature scheme that Bitcoin may adopt in the future. It is currently unclear which post-quantum signature scheme Bitcoin will use in practical applications. Lindell believes it is unlikely that a single signature scheme will be universally adopted, so preparations must be made for different outcomes across various blockchains.Coinbase is custodian for approximately $250 billion in assets for institutions such as BlackRock. Traditional Multi-Party Computation (MPC) relies on key sharding, but many post-quantum signature schemes may be "not friendly to MPC"; for example, hash-based signatures lack the arithmetic structure required for traditional cryptographic key splitting. Although cryptographers like Dan Boneh are researching relevant solutions, this research is still in a highly experimental phase, and it remains uncertain whether a viable MPC-like solution for hash signatures can be developed.To this end, Coinbase is exploring a backup architecture centered around programmable Hardware Security Modules (HSM), where private keys will be encrypted with post-quantum cryptography and assembled only within physically secure HSMs. Lindell stated that while the completion timeline is uncertain, once finished, "I will be able to say, I can support any scheme," without worrying about a blockchain adopting a signature scheme that it cannot support.

Arthur Hayes published a new long article titled "Safety First," with the core argument that the claims of "safety first" by Anthropic, OpenAI, and SpaceX, which lead to a slowdown in AGI development, are not out of concern for human welfare but rather due to economic realities. The market does not want AI; it wants AI at "Chinese prices," meaning it needs intelligence that is 100 times cheaper than what is currently available. Hayes points out that "safety first" essentially destroys the demand for computing power. If the spending on training new models decreases and laboratories shift towards efficiency optimization, customers will spend less on computing power. The three major AI laboratories do not generate any profits, and their demand for computing power supports over $10 trillion in investment-grade debt and hundreds of billions in low-quality debt, which rely on profitable tech companies like Nvidia, Broadcom, Google, and Microsoft for off-balance-sheet endorsements. The real backstop is the holders of insurance policies in the United States.Hayes cites an analysis by Nick Nameth that reveals a "self-insurance scam": private equity giants (such as Apollo, KKR, Brookfield, etc.) acquire insurance companies, stuffing AI data center debt and SaaS private credit impacted by AI into insurance assets, and then provide false endorsements with minimal capital through affiliated self-insurance reinsurance companies. Nameth estimates that the total amount of these false reinsurance assets reaches $1.54 trillion. Once the AI data center debt is downgraded by rating agencies due to insufficient demand for computing power, insurance companies will be forced to add capital, while the affiliated reinsurance companies will be unable to pay, leading to insolvency for the insurance companies. In most states in the U.S., the insurance protection limit is only $250,000 to $300,000, and existing insurance companies only pay into the protection fund afterward, which encourages all parties involved to maximize risk-taking. When AIG was bailed out in 2008, TARP funds ultimately flowed to Goldman Sachs and led to record bonuses, while the general public only received foreclosure notices; Hayes believes this scenario will repeat itself.For cryptocurrency investors, the conclusion is a win-win situation. If the U.S. government chooses to become the "last buyer of computing power," it will print money in the name of national security to fund unproductive economic goods, driving up financial speculation and Bitcoin prices; if the government chooses to bail out insolvent insurance companies, it will also need to print money to cover bad AI debts, increasing the money supply and pushing up Bitcoin. Hayes specifically points out that the Federal Reserve voted unanimously last week to raise interest rates by 25 basis points, and RMP bond purchases have stopped since August 14, but commercial banks have taken over to create over $100 billion in currency, and the interest rate hike allows banks to earn an additional $7.5 billion in excess reserve interest each year. This money will be used to expand loans and market speculation, and the net effect remains stimulative. The fluctuations in the cryptocurrency market, which saw a slight increase at the end of August, are about to end, the supply of dollars will continue to grow, and Bitcoin and some selected altcoins will rise. Hayes also described this situation as "incredibly wonderful," stating that the government will not allow the free market to stop building AI data centers, there will be an oversupply of spot computing power, the usage of AI agents will increase, and the surge in money printing will drive investors to chase cryptocurrency assets.

The U.S. House Financial Services Committee passed the amended H.R. 8957, the U.S. Reserve Modernization Act, with a vote of 28 to 21, aiming to incorporate the U.S. strategic Bitcoin reserve and digital asset reserve program into federal law. The bill proposes that Bitcoin legally held by the federal government and without other statutory purposes must be held for at least 20 years from the effective date of the bill, during which it cannot be sold, exchanged, auctioned, pledged, or disposed of in any other way.The bill still needs to be passed by the House, the Senate, and signed by Trump. The bill also requires the Treasury Department to establish relevant reserves within 180 days of its enactment and to publish an annual reserve certification report covering holdings, transactions, and private key control. The Treasury Department and the Department of Commerce will study legal and budget-neutral ways to increase Bitcoin holdings, but this provision does not authorize direct purchases.
