Walmart plans to launch an AI shopping agent feature within a month, allowing users to set spending limits and revoke permissions at any time.

Crypto analyst Axel Adler Jr. noted in a post that as of October 21, the share of funds from new investors in the Bitcoin network has climbed from the year-to-date low of 6.6% on July 5 to 11.2%, a sign that new capital is gradually flowing back, though the inflow remains below the levels that topped 20% in 2024 and 2025. Currently, Bitcoin is trading at roughly $82,300, with short-term holders’ average cost basis at $75,100, translating to an overall unrealized profit of around 9.5%. This cohort has been in profit for 63 straight days since August 20, with the unrealized profit ratio hitting a peak of 16% on October 5. Should the new investor fund share break above 11.5%, it would signal further strengthening of buyer demand; a drop back below 10%, meanwhile, would point to a possible stall in new capital inflows. If Bitcoin falls below $75,100, short-term holders as a whole will flip to losses, and the associated selling pressure may rise accordingly.

According to South Korean media reports, Tesla and NVIDIA will invest 1.1 trillion won and 2.6 trillion won respectively, totaling around 3.7 trillion won (approximately $2.5 billion), to support Samsung Electro-Mechanics’ expansion of next-generation FC-BGA (Flip Chip Ball Grid Array) substrate production facilities. Samsung Electro-Mechanics will set up a dedicated production line at its Sejong plant for Tesla; the substrates manufactured will be used in AI chips for Tesla’s autonomous vehicles and its Optimus humanoid robot. The relevant long-term supply agreement spans five years, from 2029 to 2033. NVIDIA, meanwhile, plans to invest in the expansion of Samsung Electro-Mechanics’ Sejong and Busan plants to produce AI computing chips and data center network substrates. Samsung Electro-Mechanics targets completing factory construction by the end of 2027, launching mass production in the second half of 2028, and commencing supply to Tesla in 2029. FC-BGA is a critical packaging substrate for high-performance chips including AI accelerators, GPUs, and CPUs. As AI chip computing power rises, the supply of such substrates has emerged as a key bottleneck in the industry chain. The partnership is expected to help Samsung Electro-Mechanics scale its high-end substrate production capacity and secure long-term customer demand.

Against the backdrop of rising Middle East tensions and mixed tech earnings results, global market risk sentiment has cooled. The Korea Composite Index fell over 4%, SK Hynix dropped more than 5%, and Samsung Electronics declined over 4%; the Nikkei 225 index fell around 2.65%, while the MSCI Asia Pacific index slipped 1.72%, hitting its lowest closing level since the end of July. In U.S. markets, Nasdaq futures fell 1.5% and S&P 500 futures declined 0.8%. In energy markets, Brent crude rose 2% to $111 per barrel. The U.S. State Department ordered non-emergency diplomatic personnel and their families at its Saudi Arabia embassy to evacuate, further stoking concerns over escalating Middle East tensions and disrupted oil supplies. Risk-off sentiment pushed U.S. Treasury prices higher: the 30-year Treasury yield fell 3 basis points to 5.38%, the U.S. dollar dropped 0.5% against the Japanese yen to 157.34. Precious metals also weakened: spot gold fell 1.04% to $4,097 per ounce, and spot silver declined 3.21%, briefly dipping below $56 per ounce. Bitcoin dropped over 2.7% on the day to around $82,200. In tech stocks, Tesla fell 3.3% in after-hours trading after cutting its capital expenditure forecast; Meta rose 2.14% in after-hours trading following an upward revision to its AI-related spending outlook; Lam Research dropped 7.21% in after-hours trading due to weaker-than-expected performance guidance. Market scrutiny of AI investment returns and commercialization prospects continues to intensify, as investors shift focus from capital expenditure size to evaluating actual performance and monetization capabilities.

US private nuclear fusion startup Marathon Fusion announced in a post early this morning that it has successfully achieved high-efficiency alchemy: converting mercury into real, stable gold. According to its video presentation, Marathon Fusion uses beam-driven fusion technology to transform mercury-198 into mercury-197, which decays into stable gold-197 after roughly 64 hours; the process also breeds tritium and generates electricity. Lab simulations indicate that each GWth can produce over 2 tons of gold annually, potentially doubling the economic value of power plants. Market analysts pointed out that the technology remains in the small-scale laboratory demonstration phase, with output far from commercial levels, so it has almost no material impact on gold in the short term. However, if the technology matures and is commercialized in the future, it theoretically has the potential to disrupt gold market fundamentals. Public information shows that Marathon Fusion is a San Francisco-based private nuclear fusion startup founded in 2023, focusing on full-stack nuclear fusion research and dedicated to solving the fuel cycle challenges of fusion reactors.

Renaiss Earn is a staking yield product launched by Renaiss, a physical collectibles tokenization protocol built on BNB Chain. After physical collectible cards are authenticated, custodied, and tokenized, holders can deposit the on-chain assets corresponding to eligible cards into staking pools to earn USDT yields per relevant rules, generating returns during their holding period without selling the cards. According to Renaiss, the first-phase staking pool was fully subscribed just 30 minutes after launch. All four current staking pools are now fully subscribed, with a total of 1,593 collectible cards staked, valued at over $200,000. The four staking pools all offer an annual percentage yield (APY) of 48% with a 60-day lock-up period. As a tokenization infrastructure for physical collectibles, Renaiss converts physical collectibles into programmable on-chain assets via authentication, custody, and tokenization, providing foundational support for the collectibles market in asset onboarding, circulation, and integration with financial applications. Building on this, Renaiss has developed features including trading, verifiable draws, and staking yields, expanding the on-chain use cases of physical collectibles.
