The Fed held rates at 3.75% to 4.00% on Wednesday as Chair Kevin Warsh said it will begin shrinking its rate-setting calendar in 2027. Only seven of eight meetings in 2027 and six of eight in 2028 are expected to set rates, according to BeInCrypto. Strategy-only meetings would have no policy statement or rate vote and are intended to give FOMC members room to debate long-term issues. The hold drew a 10-2 vote, with Lisa Cook and another official dissenting in favor of a hike. Warsh said first-half growth estimates rose to 2.4% from 1.8%, while inflation has topped target for nearly six years; new data will inform the December rate decision. Fewer scheduled decisions could leave Bitcoin and other rate-sensitive assets with fewer catalysts.

Ethereum co-founder Vitalik Buterin said AI is highly knowledgeable but not very wise, often detecting references while making only surface-level judgments about a text’s argument. His remarks came in an X debate over whether chatbots rival the best human readers, according to BeInCrypto. Buterin said judgment is especially difficult when a model encounters a text for the first time, a concern for crypto teams using AI to review whitepapers, audits and governance proposals. He recently warned AI could weaken key parts of crypto security within two years.

Hong Kong-regulated tokenized gold XAUa has launched on Sui. According to Odaily, AlphaToken issued the token under Sui’s Permissioned Asset Standard (PAS), while TBook handles distribution to on-chain users. Each XAUa is backed by physical gold stored in Hong Kong, and eligibility requirements apply to purchasing and holding the token.
PAS allows issuers to encode compliance rules in policies. Each transfer must pass validation before settlement; transfers that fail are rejected, and balances remain unchanged. TBook has migrated and rebuilt its treasury issuance platform on PAS, allowing future real-world asset issuers to issue treasuries on Sui with similar compliance controls.

Hyperliquid Labs said order, cancellation and trade records are publicly available on-chain for real-time review. Trade.xyz, the contract issuer, said the platform has order limits and ongoing monitoring mechanisms.

Strategy shareholders approved changes allowing the company’s four preferred stocks to pay dividends every business day, with 99.3% of votes cast supporting the amendments, according to preliminary results released Wednesday. According to Cointelegraph, the changes apply to STRF, STRC, STRK and STRD, replacing semi-monthly or quarterly payment schedules while leaving annual dividend rates unchanged. Dividends will accrue daily, including on weekends and holidays. Strategy expects daily payments for STRC to begin Nov. 2, followed by STRF, STRK and STRD on Jan. 4, 2027.

STRK also gives investors the option to convert their holdings into Strategy common stock.

Thailand's Supreme Court recently ruled in criminal case No. 4929/2569 that Bitcoin qualifies as property under the law because it has market value, can be held and traded, and can be exchanged for cash when a buyer is available. According to Odaily, the case involved a victim who exchanged $50,000 for Bitcoin and transferred it to a criminal group; the court said the Bitcoin was not valueless intangible data but property that could be the subject of a property crime. The ruling recognized Bitcoin as property protected by law and potentially subject to criminal acts, but did not grant it the same legal tender status as the Thai baht.

Days later, former Mt. Gox CEO Mark Karpelès said a Ledger Flex he bought at Singapore’s airport contained a spy implant. Another Ledger user said a tampered device he purchased from local IT retailer Challenger was later replaced with a new device sent by Ledger. On Oct. 13, Ledger said it had asked retailers in Indonesia, Singapore, Thailand, the Philippines, Vietnam, Malaysia and Hong Kong to suspend sales of its devices while investigations continued. Singapore police said they are in contact with Ledger, which is reviewing the affected cases, as police investigations remain ongoing.

According to Foresight News, the draft removes withdrawal-address paths, execution-layer request contracts, and pending authorization queues, so registration can be authorized using existing BLS signing keys.

Bitcoin closed below $83,000 for a second straight week, reinforcing analyst Benjamin Cowen’s view that the move was a fake-out. Cowen fears Bitcoin could follow silver’s 73% collapse over four years after its 2011 peak, according to BeInCrypto. He says Bitcoin could next test the $72,000-$76,000 bull-market support band; a weekly close above roughly $84,000 would weaken his bearish thesis. Charles Edwards, founder of Capriole Investments, said Bitcoin’s put/call ratio reached 1.46, a level he associates with locally capped downside, while noting there are no guarantees.

Crypto wallet provider Phantom has launched prediction markets for eligible US users through an integration with Kalshi, enabling users to trade on crypto prices, sports and other real-world events within the app. According to Cointelegraph, the Wednesday announcement said the service includes CFTC-regulated event contracts, including short-term Bitcoin price markets that settle every 15 minutes. Users can fund trades with balances in Phantom Cash, which are denominated in the CASH stablecoin. Kalshi is responsible for customer verification, account management and trade execution, while Phantom provides access through its wallet app. The service is rolling out in a new Predict tab, with availability varying by state and market category. Eligible users can view live market data, sports scores and market discussions before placing trades through an interface designed to resemble a cryptocurrency token swap. The launch follows no-action relief granted by the Commodity Futures Trading Commission in March. That relief allows Phantom to connect users to regulated markets without registering as an introducing broker, subject to certain conditions.
Phantom’s move into prediction markets comes as Kalshi faces legal challenges in the United States. On Monday, the Commodity Futures Trading Commission sued Utah after the state challenged Kalshi’s event contracts under its gambling laws. The case adds to disputes over whether federal derivatives regulation takes precedence over state gambling laws, an issue at the center of legal challenges involving prediction markets. Trading activity has continued to rise amid that uncertainty. Kalshi recorded $10.8 billion in crypto contract volume during the 30 days ending Oct. 27, a 19.6% increase from the previous period, according to data compiled by DeFi Rate. The reported period ran from Sept. 28 to Oct. 27, 2026. The volume figures relate to Kalshi’s crypto contracts, while Phantom’s new service offers access to a broader set of event categories, including sports and real-world events. The launch combines Phantom’s in-app access with Kalshi’s handling of verification, accounts and execution, while users’ eligibility and the markets available to them depend on their state and market category.

According to ChainCatcher, JPMorgan, Morgan Stanley, Standard Chartered, Visa and Fiserv are among the financial institutions and payment networks already conducting related business on Solana.
The shift comes as a subdued crypto market and the rise of competitors such as Hyperliquid challenge Solana’s growth model.

Solana’s share of on-chain perpetual futures trading volume has fallen from 17% to 6%.

Shares of bitcoin treasury company Datavault AI (DVLT) fell 49.55% to close at $0.067 on Tuesday, October 27, after a regulatory filing revealed it had been unable to withdraw bitcoin from crypto exchange Biconomy since June and would restate its financial results. About 244 million shares changed hands.A Bitcoin-Funded Share SaleThe problem dates to a September 2025 agreement under which Scilex Holding Company agreed to buy $150 million of Datavault shares and warrants using bitcoin. Scilex credited 1,309.04 BTC to Datavault’s account at Biconomy through off-chain transfers, meaning balances changed within the exchange rather than on the Bitcoin blockchain. Datavault later sold 491.4 BTC back to Scilex for about $40.5 million in cash. When Datavault asked to withdraw its bitcoin to an external account in June, the transfer could not be completed, and it remained incomplete as of Monday’s filing.Biconomy on Both SidesBiconomy also supplied the bitcoin behind the investment. Scilex’s June financial report says it sold $200 million of shares in its subsidiary Semnur to Biconomy for bitcoin, then used $150 million of that to buy Datavault securities.$92 Million Removed From Reported AssetsDatavault now says the bitcoin credited through Scilex’s investment should have been recorded as an amount Scilex owed for its shares, reducing shareholders’ equity, rather than as a cryptocurrency asset. The correction will reduce reported assets by $92.2 million at the end of 2025 and $49 million as of June 2026. Datavault had counted the bitcoin balances as funds available to run the business and must now revisit that assessment. Biconomy did not respond to CoinDesk’s request for comment.

The Federal Open Market Committee said the unemployment rate had changed little. According to ChainCatcher, the assessment appeared in the committee’s statement.

According to Jin10, Alphabet (GOOG.O) shares fell sharply after the company reported disappointing third-quarter results, dropping more than 10% at one point after hours. The decline has left the final major stock investment made during Warren Buffett’s tenure as Berkshire Hathaway chairman performing poorly.
Berkshire bought Alphabet shares heavily in the first half of 2026. In early June, it participated in Alphabet’s $85 billion share offering, purchasing $10 billion worth of shares at about $350 each. Buffett said in July that the decision to buy Alphabet shares was his own.
Berkshire’s average cost is unknown but is likely above $300 per share and may have been close to $320. As of June 30, Berkshire held 106 million Alphabet shares, worth about $30 billion based on the after-hours share price, down from a June peak of $37 billion. Alphabet is Berkshire’s fourth-largest stock holding, behind Apple, American Express, and Coca-Cola.

According to CNBC, U.S. District Judge David Carter rejected the Justice Department’s request to temporarily block California from counting mail ballots from more than 20,000 registered voters it alleges may be noncitizens.

The Justice Department appealed the decision to the 9th U.S. Circuit Court of Appeals.
