1. Key Events

1. Marvell beat across the board — and sold off hard. @wallstengine reported $MRVL FY27Q2 revenue of $2.7B and adj. EPS of $0.94 (both beats), data center revenue $2.2B (+46% y/y), and Q3 guidance of $3.15B (also a beat) — yet the stock closed down 10.28% at $216.62, among the day's worst performers. A textbook "good news already priced in" reaction. 𝕏
2. Hawkish Warsh comments lifted yields; September hike odds jumped. @DeItaone quoted Kevin Warsh saying summer inflation data came in better than expected but the underlying trend hadn't meaningfully changed, and the 2% PCE target is unwavering. @Schuldensuehner logged US 2Y yields jumping 6bps and the 2s/30s spread narrowing 8bps to 87.5bps; @biancoresearch put September hike probability at 49%, up from 36% pre-speech. 𝕏¹ 𝕏² 𝕏³
3. Elastic was the day's biggest winner. @wallstengine reported $ESTC FY27Q1 revenue of $478M and adj. EPS of $0.70 (both beats), FY27 guidance raised to $2.00–2.01B, plus the acquisition of Deductive AI and a partnership with OpenAI. The stock closed +19.31% at $99.91. 𝕏
4. Rubrik also beat and raised — and was also sold. @wallstengine reported $RBRK Q2 revenue of $427.3M and adj. EPS of $0.20 (beats), FY27 revenue guidance raised to $1.685–1.693B, and the launch of Rubrik AI. The stock closed down 13.05% at $93.05. Together with MRVL, this defines the week's "beat-and-raise still gets sold" regime. 𝕏
5. Anthropic secured 460MW of data center capacity; Google and Microsoft lost out. Per @wallstengine, Google and Microsoft had both been in talks to lease Nscale's West Virginia data center capacity, but the 460MW ultimately went to Anthropic in a deal sized around $45B — AI compute leases are shifting from hyperscalers toward model companies directly. 𝕏
6. NVIDIA issued its first-ever year-ahead guide, but supply remains the bottleneck. Both @SKundojjala and @dnystedt quoted the call: management expects FY28 revenue to grow ~70% y/y; supply and capacity commitments jumped from $119B to $279B in a single quarter; VR production shipments began in August and are guided to 20% of Q3 data center revenue. The CFO stated supply will remain a bottleneck "at least through the end of fiscal year 28." $NVDA still closed down 4.57% at $217.55. 𝕏¹ 𝕏²
7. Strike risk surfaced at Micron Taiwan. @dnystedt reported that support for a strike over bonus pay hit 80% in a preliminary survey, noting Taiwan accounts for roughly 60% of Micron's global capacity and anchors the bulk of its advanced HBM output. $MU closed down 0.27% at $932.86. 𝕏
8. NVIDIA paused its credit-for-revenue-share model with AI cloud companies. @dnystedt reported the pause stems from possible anti-trust concerns, with existing deals unaffected — this model had been viewed as a key funding channel for the neocloud complex. $IREN closed down 12.53%. 𝕏

2. Institutional & Media Coverage

Factual reporting

• Dense earnings slate (@wallstengine as primary source): beyond MRVL / ESTC / RBRK, $WDAY posted FY27Q2 revenue of $2.65B and adj. EPS of $2.75 (both beats), raising FY27 non-GAAP operating margin guidance to 31%. $WDAY closed +5.76% at $204.72, one of the few software names where a beat was actually rewarded. 𝕏
• Next week's earnings calendar (@eWhispers): the week of August 31 includes $LULU and $GAP. Notably, both already rallied on August 28 — $GAP +12.94% to $23.48 and $LULU +5.05% to $120.81 (moves from exchange data, not from the post). 𝕏
• Rates (@Schuldensuehner): beyond the 2Y move, the curve flattened after Warsh's remarks, with 2s/30s down to 87.5bps — consistent pricing of "tighter front end, growth-constrained long end." 𝕏
• Southbound flows and HK tech (@cnfinancewatch): reported net southbound buying of HK$3.18B, including HK$492M into Xiaomi, and argued HK tech sentiment is spilling over into the A-share STAR board; a separate post cited Tencent's "buyback plus new AI model launch" dual catalyst. Actual HK closes: Hang Seng +0.07% at 25,584.79; Tencent +1.65% at HK$455.20; Xiaomi-W +1.24% at HK$27.82 (exchange data). 𝕏¹ 𝕏²

Views / ratings

• @SKundojjala on Marvell: "F27 (C26) revenue raised by $500M (+45% y/y) while F28 (C27) revenue raised by $1.5B (+50% y/y); incremental largely driven optical connectivity though custom is also a part… F28 custom still expected to >2x y/y (not capped); F29 custom >$10B target reiterated with upside bias." The most bullish sell-side-style read of the print — in direct conflict with the stock's -10.28% close. 𝕏
• @jukan05 quoting Marvell's call: "Amid growing inference demand and memory scarcity, customers are revising their plans to expand their use of the technology… Scale-up optics has accelerated further from the roughly $300 million FY28 outlook… CXL memory expansion and AI inference accelerators are representative examples." 𝕏
• @dnystedt quoting SK Hynix's CEO: "the global memory chip shortage is expected to last until the end of 2030 and… the risk of oversupply is low since memory chips are no longer 'just commodities' in the AI era," with next-gen HBM in 2029. Among the longest-duration memory upcycle calls of this window. 𝕏
• @jukan05 (HBM supply chain, exclusive): "Samsung Takes Early Lead in Nvidia's 'NVHBM' Following HBM4… Samsung Electronics is developing an 8-high HBM4E… Nvidia has also asked Samsung to target speeds of 17–18Gbps per pin… optimized for Nvidia's proprietary NVLink." 𝕏

Not found: no in-window posts were retrieved from the Chinese-asset media accounts (@yicaichina, @CnEVPost, @WorksBamboo, @thePandaily) — repeated searches returned empty. HK-side coverage in this report is therefore materially thinner than US-side, as disclosed.

3. KOL Bull & Bear Views

Bullish

• @KobeissiLetter (≈946 likes / 125 reposts): "The S&P 500's total market cap has surged +$1.75 trillion since Q2 earnings season began… The Technology sector alone accounts for +$1.39 trillion of that gain, or ~79% of the total… Big Tech has never been bigger." 𝕏
• @KobeissiLetter (≈714 likes / 83 reposts): "AI is driving a historic surge in investment: High-tech capital spending accounted for 55.2% of total nominal capital spending in the US economy in Q2 2026, the highest proportion on record… combined CapEx across Amazon, Google, Microsoft, and Meta is projected to surpass $1.1 trillion by 2027." 𝕏
• @KobeissiLetter (≈964 likes / 105 reposts): "Over the last 10 years, the S&P 500 has outperformed US Treasuries by 15 percentage points on average per year, the largest outperformance since the late 1950s… The gap between stocks and Treasuries has rarely been wider." 𝕏
• @SKundojjala (≈31 likes / 7 reposts): on NVIDIA — "First-ever year-ahead guide; FY28 revenue up 70% y/y; supply-constrained… Supply and capacity commitments jumped from $119B to $279B in one quarter… VR production shipments started in Aug; guided to 20% of 3Q DC revenue; expected to be the fastest ramp in company history." 𝕏
• @dnystedt (≈112 likes / 12 reposts): relaying SK Hynix's shortage-through-2030 call — the longest-dated bull argument on the memory/HBM chain. 𝕏
• @cnfinancewatch (≈13 likes / 2 reposts / 8,244 views): net southbound buying of HK$3.18B with HK$492M into Xiaomi, arguing HK tech sentiment is spilling into A-shares. 𝕏

Bearish

• @KobeissiLetter (≈5.3k likes / 485 reposts — the highest-engagement post of the window): "Just as long-term yields were beginning to cool down, the 30Y Yield is now back up to 2008 levels. Fed Chair Warsh just said the Fed is committed to their 2% inflation target and inflation remains 'too high.' This immediately sent yields higher… We now have a hawkish Fed, record deficit spending, persistent inflation, and an ongoing global energy supply shock. The US Treasury is fighting an uphill battle." 𝕏
• @biancoresearch (≈71 likes / 4 reposts): "Probability of a September hike now 49%, up from 36% right before the speech dropped. The Fed is panicking a little more. Restated, if the Fed does something about inflation (hike), bond yields can stop rising." 𝕏
• @RyanDetrick (≈270 likes / 26 reposts): "the worst Septembers ever have usually seen weakness coming into them. In fact, the 10 worst Septembers ever saw the S&P 500 negative YTD coming into them nine times." 𝕏
• @Schuldensuehner (≈536 likes / 77 reposts): "US 2y yields jump by 6bps as Fed's Warsh sees work to do if inflation not moving to 2%." 𝕏
• @charliebilello (≈242 likes / 56 reposts): "Global Central Bank Update: South Korea hiked rates for the 2nd month in a row, 25 bps move up to 3.00%. Policymakers signaled more hikes to come." 𝕏
• @dnystedt (≈162 likes / 15 reposts): "Support for a strike at Micron Taiwan over bonus pay hit 80% in a preliminary survey… Taiwan accounts for roughly 60% of Micron's global production capacity, and anchors the bulk of advanced HBM output." 𝕏
• @dnystedt (≈40 likes / 2 reposts): "Nvidia paused a deal with AI cloud companies that offered credit support for a share of revenue due to possible anti-trust concerns… The model is still in place for existing deals." 𝕏

Retail / long-tail sentiment (broad search)

Retail-level chatter in this window was notably sparse, with no dense discussion threads. Usable items: @high_tech_stock's Nasdaq/SOX weekly noting "SOX estimated contribution TOP NVDA +0.186pt / BOTTOM MRVL -0.442pt" (≈4 likes) 𝕏; @jeromedok: "$NVDA earnings just gave the market a jolt, and $BTC pushed back toward $80K… Strong AI earnings pulling risk assets up while tighter policy pulls the other way" (≈3 likes) 𝕏; and @jharahul311992 on HK, noting the Hang Seng remained range-bound with resource and defensive names bid and style rotating further defensive (0 likes) 𝕏. All are low-engagement long-tail posts and should be treated as directional color only, not a valid sample.

4. Buzz & Sentiment Shifts

US broad market: Buzz concentrated on the anomalous "beat but sell" combination, running above a typical weekend but without one-sided positioning. All three indices closed slightly lower — Dow 53,559.99 (-0.02%), S&P 500 7,711.76 (-0.25%), Nasdaq Composite 26,402.42 (-0.52%) — with the decline led by tech, precisely matching the KOL narrative of "strong AI earnings, rates pulling the other way." The marginal sentiment driver versus the prior session was Warsh: @KobeissiLetter's hawkish warning post drew 5.3k likes, dwarfing his own three bullish market-cap/capex posts. Marginal attention is rotating from the AI narrative toward the rate constraint.

Semis & AI hardware: The highest-buzz sub-sector. Bullish arguments (NVDA's FY28 +70% guide, doubled capacity commitments, SK Hynix's shortage-to-2030 call, Marvell's raised custom silicon outlook) were near-unanimous among professional KOLs — while the tape went the other way: NVDA -4.57%, MRVL -10.28%, AVGO -0.74%, AMD -2.33%, KLAC -4.48%, INTC -2.85%. This divergence between overwhelmingly bullish expert commentary and broad-based price weakness is the single most notable signal of the window: the market is pricing valuation and rates, not fundamentals.

Crypto-adjacent and high beta: Sentiment clearly deteriorated with no KOL support. $MARA -10.11%, $CLSK -9.96%, $IREN -12.53%, $MSTR -7.34%, $BMNR -7.14% — coinciding with the news that NVIDIA paused its neocloud credit model.

Hong Kong: Buzz was materially lower than for US equities — only three usable HK-related posts across all three search tracks, with mainstream Chinese finance media accounts returning no hits at all. The Hang Seng closed marginally higher (+0.07%), diverging from US direction. Structurally, southbound inflows into tech (Tencent +1.65%, Xiaomi +1.24%) coexisted with the long-tail observation that resource and defensive names were bid — a low-volatility style rotation rather than a directional breakout. Given the thin HK sample on X, confidence in this paragraph is lower than for the US sections.

5. US Options Flow

Post-close scan of 162 liquid names, as of 2026-08-29 05:41 ET; interpretation only. US equities only.

Deeper reads:

First, AMZN's two-sided positioning is the most interesting. On one side, the $295 call with vol/OI of 14.8 (48k contracts opened, $41.4M premium); on the other, the $265 put expiring in 2 days with vol/OI of 193.8 — the strongest new-position signal in the entire scan. $AMZN closed +3.97% at $266.43, one of the few mega-caps that rose. The short-dated put reads as protection on realized gains, while the 83-day $295 call is a directional bet on AI cloud plus the retail peak season. Together: large accounts are bullish on Amazon over the medium term but hedged against a two-day give-back.

Second, semiconductor options flow contradicts semiconductor KOL sentiment. NVDA $200 puts (33d) at vol/OI 45.8 and $16.9M of new premium; AMD $410 puts (34d) at vol/OI 74.5 and $10.9M; KLAC $224 puts at $21.2M with 60% IV. Stacked together, this is systematic downside protection for September semis — in direct conflict with the uniformly bullish fundamental narrative from @SKundojjala, @dnystedt and @jukan05 in Section 3. The reasonable reading is that holders of large semi长 positions are buying insurance rather than flipping short, since NVDA $200 calls (138d) simultaneously drew $70.6M in premium.

Third, the MU $1300 call (139d, 63% IV, spot ~$933) is a pure convexity bet. Struck 39% above spot, and set against SK Hynix's "shortage through 2030" comments plus the Micron Taiwan strike risk, that $26.6M of premium is buying a runaway-memory-price tail scenario, not a base case. The coexisting $700 call ($19.7M) is deep-ITM stock replacement — on the same expiry, large money is buying both leverage and convexity.

Overall sentiment: market-wide Put/Call premium ratio is 0.82, still in bullish territory. But structurally, the largest bullish premium sits in medium-to-long-dated calls on mega-cap weights (MSFT/AMZN/NVDA), while the most actively opened contracts are almost uniformly short-dated puts on SPY/QQQ/NVDA/AMD. "Long-term bullish, short-term hedged" is the cleanest picture of this weekend's options market — logically consistent with @RyanDetrick's September seasonality warning and @biancoresearch's jump in hike probability.
