ChainCatcher, citing Binance spot market data, reported broad volatility across major altcoins. LINK rose 10.68% over the past 24 hours, reaching both a fresh intraday high and a new high for the week. NEAR also posted gains, climbing 6.11% and touching its weekly high. On the losing side, BICO fell 16.39% after a spike-and-retreat pattern. GTC, YGG, BMT, and HAEDAL showed the same price action, with declines of 5.06%, 5.57%, 8.12%, and 7.24%, respectively. At the same time, MITO and AT moved in the opposite direction, rising 6.82% and 12.01% after a rebound from earlier lows. The update points to a market session marked by fast rotations, with some tokens extending gains while others gave back earlier advances.

A PANews analysis argues that August 4, 2026 marked a turning point for the memory industry. On the same day, SK hynix and SanDisk introduced the first standard for high-bandwidth flash, or HBF, at FMS 2026, while TrendForce reported that Nvidia was evaluating lower HBM configurations for Rubin Ultra. The article says those two developments point in the same direction: the core constraint in AI infrastructure is shifting away from on-package memory alone and toward interconnects across chips, packages, racks, and systems. The piece traces that shift through Nvidia’s Vera Rubin launch, NVLink 6 bandwidth gains, Spectrum-X CPO shipments, Intel’s EMIB-T packaging push, TSMC’s reported work on an EMIB-like approach, and the emergence of UCIe-linked memory tiers such as HBF. In that framework, optical and electrical interconnects sit at the top of the stack, advanced packaging becomes the physical foundation, HBM remains essential but less open-ended from an investment perspective, HBF represents a new category aimed at inference-era capacity pressure, and CXL memory pooling remains an option for later years. Rather than framing this as a broad “memory bull market,” the article’s main point is that value inside the storage empire is being redistributed as the bottleneck migrates.

Volatility picked up in Binance spot trading, according to market data cited by ChainCatcher. AAOIB posted the strongest move among the tokens mentioned, rising 13.99% over the past 24 hours and reaching a new intraday high. EPIC gained 8.1% and was described as rebounding after touching lower levels, while PLTRB also climbed to a new daily high with an 8.19% increase. On the downside, GTC gave back earlier gains and fell 9.38%, showing a sharp reversal from higher levels. ATM also moved lower, touching a new weekly low with a 5.49% decline. The snapshot reflects broad short-term turbulence across several tokens in Binance spot markets, with both breakout moves and pullbacks appearing at the same time.

SemiAnalysis said Nvidia has shown key customers a preview of Rubin Ultra, but the product’s specifications have slipped further from earlier expectations. The research firm said Rubin Ultra still targets 35 PFLOPs of peak theoretical compute, matching Rubin, while memory capacity has been cut to 192GB using 8-Hi stacks, below Rubin’s 288GB with 12-Hi stacks. Memory bandwidth rises by just 1 TB/s, and power ranges from 1,800 W to 2,600 W, with the upper end higher than Rubin. The report argues Nvidia is reworking Rubin Ultra around system-level scaling instead of pushing more expensive HBM into each chip. It said the biggest change is scale-up connectivity: Rubin Ultra’s supported GPU cluster size rises from 72 GPUs to 576 GPUs through NVLink under the NVL576 architecture. SemiAnalysis also said HBM3 pricing climbed from $180-$220 per stack at a low in Q2 2025 to $600-$700 in contract pricing in Q1 this year and $700-$850 in spot pricing in Q2. On its estimates, Rubin Ultra rack-level BOM cost had risen from about $6.6 million to $8 million, but could fall back to about $6.4 million after the design adjustment. Following the report, South Korean memory stocks fell, with SK Hynix and Samsung down about 8% and the KOSPI down about 5% as of 11:45 Beijing time.

Market discussion around a supposed Nvidia Rubin HBM downgrade does not apply to the standard Vera Rubin NVL72 systems that are already being delivered, according to a clarification posted by analyst qinbafrank on Aug. 2. The uncertainty instead concerns Rubin Ultra, the upgraded version originally slated for the second half of 2027, whose final configuration has yet to be locked in. The post said Vera Rubin is moving ahead smoothly. Dell delivered the first NVL72 systems to CoreWeave in early June and completed what was described as the industry’s first full boot validation. By July, dozens of customers had received test racks or early shipments, including Microsoft, OpenAI, Anthropic, Google Cloud, Oracle, Nebius and SpaceX AI, with some units already running in customer data centers. Larger-volume deliveries are expected to begin in the fall, and the overall schedule was described as running ahead of Blackwell, with rack assembly time cut to roughly five minutes. The debate is focused on Rubin Ultra. A configuration shown at GTC 2026 called for four compute dies near reticle limits and 16 HBM4E stacks for roughly 1 TB of memory in a single package. Reports from SemiAnalysis and others in late June questioned that design, citing TSMC CoWoS-L substrate warping, reticle-size constraints and yield challenges. TrendForce later said the HBM specification still had not been finalized.

ChainCatcher, citing Binance spot market data, reported sharp moves across several tokens over the past 24 hours. BANK rose 15.93% and AXTIB gained 8.83%, with both described as rebounding after hitting lower levels. On the downside, FLNCB pulled back after an earlier rise and posted a 9.88% loss. EGLD fell 8.97% after touching a weekly low, while ESP dropped 10.42% after hitting a daily low. COTI and GTC were also listed as showing a rise-then-retreat pattern, down 14.9% and 6.2%, respectively. JUV, meanwhile, reached its 24-hour high and posted a 5.96% gain. The report framed the moves as part of broader volatility in the Binance spot market.

According to ChainCatcher, citing Binance spot market data, crypto trading showed a clear split in price action over the past 24 hours. RIF rose 9.47% and showed a rebound after dipping earlier. At the same time, a group of tokens moved in the opposite direction, with CHR, CVC, GTC, ICX, SUPER, FIDA, VIC, DYM, and CGPT all posting intraday patterns described as rallying first and then pulling back. Their 24-hour declines came in at 5.69%, 5.31%, 9.85%, 5.31%, 5.15%, 5.78%, 5.47%, 6.67%, and 6.55%, respectively. Among the tokens listed, GTC recorded the largest drop. The figures point to a market that was not moving in a single direction, with gains concentrated in RIF while several other assets lost ground over the same period.

Techub, citing CryptoBriefing, reported that Nvidia posted a total return of 15,332% over the past 10 years, the strongest performance among S&P 500 constituents. In 2025, the company accounted for about 15.5% of the index’s total 17.9% return, while its market-cap weight approached 8%. The report linked that rise to booming demand for AI infrastructure, with Nvidia’s GPUs holding a dominant position in model training and inference. In the first half of 2026, however, Nvidia’s share gains slowed to 7% to 8%, trailing the broader market. The report also noted that CEO Jensen Huang’s reference to AI “tokens” at the March GTC conference briefly lifted related digital assets.
