Google's $12B chip bet on Marvell and Cerebras' inference-first machine reshape AI's hardware map, as US agencies warn hackers are now using AI-generated exploits to target the power and water grid
Marvell gives Google an option to buy up to $12.2 billion in shares as their custom AI-chip partnership expands through 2033
Marvell Technology and Google announced on 19 August that Google has been granted a warrant to buy up to 58.97 million Marvell shares at $206.58 apiece — worth roughly $12.2 billion if fully exercised — as part of an expanded custom-silicon partnership. Most of the warrant vests only as Google hits agreed purchasing milestones through fiscal 2033, in tranches tied to every $500 million of chips bought, covering processors, networking and storage silicon built around Google's TPU ecosystem rather than TPUs themselves. Analysts estimated the expanded deal could bring Marvell roughly $120 billion in revenue through fiscal 2033. Marvell shares rose on the news while Broadcom, Google's existing lead custom-chip partner, fell more than 5%.
Takeaway Tying an equity warrant to purchase volume lets Google reward a second custom-silicon supplier without writing a bigger check today, and the market read it as a genuine hedge against Broadcom and Nvidia dependence, not just a supply contract.
CNBC →Cerebras unveils its CS-4 rack-scale AI system, claiming inference speeds up to 30 times faster than GPU-based services
Cerebras unveiled the CS-4 at its Supernova event in San Francisco on 19 August, its first system built on a new “Nexus” architecture that links three WSE-3 Turbo wafer-scale processors for a combined 750 petaFLOPs of compute and 129.6 petabytes/second of memory bandwidth. The company says the system delivers more than 4,400 tokens per second per user on the open-weight GPT-OSS-120B model, versus roughly 350 tokens per second on the fastest GPU-based inference services available today. First shipments are scheduled for later this quarter.
Takeaway Cerebras is explicitly no longer competing with Nvidia on training throughput — it's betting that inference speed, the metric that matters once a model is already built and deployed, is where wafer-scale chips can still win.
Cerebras →US cybersecurity agencies warn hackers are using AI-generated exploits to target Siemens controllers in water, energy and manufacturing plants
CISA, the NSA and the FBI issued a joint advisory on 20 August (AA26-231A) describing an “active threat” against Siemens S7 Series programmable logic controllers used across water and wastewater, energy, chemical, food and manufacturing facilities. The agencies said threat actors are scanning the internet for exposed, outdated or poorly secured S7 controllers and using AI-generated exploitation scripts disguised as legitimate monitoring tools to develop attack capability against them; several outlets linked the activity to concerns about Iran-affiliated actors amid rising US-Iran tensions. CISA said “this is not a theoretical risk,” warning a successful compromise could disrupt industrial processes, damage equipment and cause safety incidents, and recommended operators inventory their S7 devices, patch them, and take them off the open internet.
Takeaway This is one of the first joint US advisories to name AI-generated exploit code, not just AI-assisted reconnaissance, as the tool threat actors are using against physical infrastructure — a meaningfully different risk category than the usual phishing-and-ransomware warnings.
CISA →Amazon plans a sixfold expansion of Prime Air drone delivery to nearly 500 US cities and towns by the end of 2026
Amazon announced on 19 August that Prime Air drone delivery, currently live from 11 sites across roughly 10 metro areas in seven states, will expand to nearly 500 US cities and towns by year-end — a sixfold increase in coverage. The next wave of markets includes Chicago, Atlanta, Cleveland, Syracuse and Boise. Drones carry payloads up to 5 pounds, covering more than 60% of Amazon's most commonly ordered items, and can deliver in as little as 30 minutes; the company projects 1 million drone deliveries this year.
Takeaway Jumping from roughly 10 metro areas to nearly 500 cities in a matter of months suggests Amazon has cleared the regulatory and unit-economics hurdles that stalled Prime Air for a decade, not just refined the flight technology.
About Amazon →Ex-Nvidia AI research chief Sanja Fidler raises over $90 million to build “world models” for physical AI at new startup Veeda AI
Sanja Fidler, who spent eight years as Nvidia's VP of AI research in Toronto, has launched Veeda AI and raised more than $90 million in seed funding — among the largest seed rounds in Canadian history — announced 19 August. She co-founded the company with former Nvidia colleagues Huan Ling and Zan Gojcic, with backing from Khosla Ventures and Radical Ventures. Veeda is building “world models”: AI systems trained to simulate physical, spatial and movement dynamics for robotics and other physical-AI applications, rather than text or image generation.
Takeaway Another senior Nvidia researcher spinning out to chase world models rather than staying to build them in-house suggests physical-AI research talent now sees more upside striking out on its own than at the company that dominates the hardware underneath it.
SiliconANGLE →Google's Pixel 11 goes on sale worldwide, bundling six months of Google AI Pro as its main pitch over camera hardware
The Pixel 11 series — Pixel 11, Pixel 11 Pro, Pixel 11 Pro XL and a Pixel 11 Pro Fold — went on sale globally on 20 August, a week after being unveiled at Google's 12 August “Made by Google” event alongside the Pixel Watch 5 and a new Pixel Tag item tracker. US pricing starts at $899 for the base Pixel 11, up from the Pixel 10's $799 starting price, with the Pro Fold reaching $1,899; every model ships with six months of Google's AI Pro subscription included. The phones run Android 17 on Google's in-house Tensor G6 chip, with camera-processing features like “Magic Capture” as the headline hardware upgrade.
Takeaway Bundling a subscription instead of just cutting the price is Google's way of using the Pixel line to seed paid AI usage habits, even as the phones themselves get more expensive.

Apple settles its App Store fight with Brussels and Starlink makes another run at India's skies, as fresh funding rounds span babycare, coffee and paediatric care
Apple overhauls its EU App Store fees and settles with Brussels, replacing a disputed tiered structure with flat commissions
Apple announced on 18 August a settlement with EU regulators that replaces its earlier, disputed App Store fee structure in the bloc with a simplified flat-commission model, locking in a roughly 5% core technology fee alongside other changes, and loosens some restrictions on alternative app stores and marketplaces operating under the Digital Markets Act. The changes also touch Apple's App Tracking Transparency rules in Germany, resolving a separate dispute there. Reaction was split: some outlets framed it as Apple finally accepting lower EU fees, while Epic Games publicly dismissed the new terms as “junk,” arguing they still favour Apple's own payment rails.
Takeaway A settlement that satisfies EU regulators but draws public scorn from Epic shows Apple has calculated it can concede just enough to end the DMA fight in Brussels without giving up the App Store economics it still hopes to defend in the US.
TechCrunch →Starlink reapplies to India's space regulator for approval of its 30,000-satellite Gen-2 constellation
Starlink has submitted a fresh application to India's IN-SPACe regulator seeking approval for its Gen-2 satellite constellation — nearly 30,000 low-earth-orbit satellites operating at 340–615km altitude, including direct-to-device technology that would let the network connect straight to ordinary mobile phones. The company's earlier Gen-2 application was rejected because some features and frequency bands didn't align with Indian rules; only its smaller Gen-1 framework, covering 4,408 satellites for traditional broadband, was cleared in July 2025. No non-geostationary satellite operator — including Starlink, OneWeb or Jio's SES joint venture — has yet begun commercial operations in India.
Takeaway A second attempt at the same approval, this time built around direct-to-device connectivity, signals Starlink sees more strategic value in India's yet-to-launch satellite-to-phone market than in repeating its earlier broadband-only pitch.
Business Standard →Babycare quick-commerce startup Peeko raises ₹67.4 crore Series A to build out its Bengaluru dark-store network
Bengaluru-based Peeko, founded in 2025 by Chetan Sharma, Vivek Khetan and Abhijit Gairola, closed a ₹67.4 crore (over $7 million) Series A on 20 August led by Chiratae Ventures, with existing investor Stellaris Venture Partners and angel investors also participating. The company runs babycare-focused quick commerce and plans to reach six micro-markets and dark stores across Bengaluru by the end of 2026 for full delivery coverage, before expanding to new cities in 2026–27. The funds will go toward expansion, technology and hiring, building toward a broader “parenting partner” positioning beyond commerce.
Takeaway A babycare-only quick-commerce bet is a wager that parents will pay for curation and speed on a narrow, high-trust category that Blinkit and Zepto's general assortment doesn't specialise in.
Inc42 →Paediatric neurodevelopmental care platform Butterfly Learnings raises ₹65 crore pre-Series B led by Inflexor Ventures
Butterfly Learnings, founded by Dr Sonam Kothari and Dr Abhishek Sen, raised ₹65 crore in a pre-Series B round on 19 August led by Inflexor Ventures, with continued participation from existing investors Insitor Partners and Enzia Ventures. The company runs more than 90 centres across 22 Indian cities providing care for children with autism, ADHD and learning disabilities. New capital will expand its centre network, strengthen its technology platform, and commercialise an early autism-screening tool the company describes as a breakthrough.
Takeaway A ninety-centre network raising a pre-Series B rather than a first institutional round shows specialty paediatric care has moved past the pilot stage into a scaling business investors are willing to back at real volume.
Entrackr →Specialty coffee chain First Coffee raises $1.3 million pre-Series A to expand beyond Delhi, Punjab and Haryana
First Coffee, a grab-and-go specialty coffee brand founded in 2024 by Sohrab Sitaram and Shiv Dhawan, raised $1.3 million in a pre-Series A round announced 19 August, led by Japanese venture firm DG Daiwa Ventures with participation from BEENEXT and individual angels including Genesis Luxury co-founder Sanjay Kapoor. The round takes First Coffee's total funding to $2.5 million; the company currently runs 25 stores across Delhi, Punjab and Haryana and plans to use the capital for store expansion into Tier 2 markets, building out a corporate team, and brand marketing.
Takeaway A Japanese venture firm backing a 25-store regional coffee chain rather than a national player is a bet that India's specialty-coffee category still has room for several regional winners before consolidation sets in.
DealStreetAsia →IPO-bound Garuda Aerospace signs an MoU with Australia's Timed Automation Solutions on autonomous drone technology
Garuda Aerospace, the MS Dhoni-backed Indian drone maker preparing for an IPO, signed a memorandum of understanding on 19 August with Australia's Timed Automation Solutions (TAS), a provider of enterprise autonomous drone platforms including drone-in-a-box orchestration and fleet control. The non-exclusive agreement covers technical cooperation, knowledge sharing, and evaluating joint product distribution and development opportunities, including pilot deployments across Australia and New Zealand.
Takeaway A pre-IPO Indian drone maker lining up an Australian distribution and technology partner is a sign it wants a growth story that extends beyond the domestic market before it goes public.
BW Disrupt →HUL sues D2C challenger Beco's parent over an ad campaign alleging chemicals in Surf Excel and Vim
Hindustan Unilever filed suit in Delhi High Court against Kwick Living, the parent of eco-friendly cleaning brand Beco, over Beco's “#WarOnWhatsHidden” campaign, which claimed lab testing found chemicals — Benzisothiazolinone and Linear Alkylbenzene Sulfonate — in HUL's Surf Excel and Vim products. HUL alleges commercial disparagement, trademark infringement and passing off, objecting to Beco's use of HUL's registered taglines, including “Daag Achhe Hain,” to identify the targeted products. Justice Anup Jairam Bhambhani declined to grant Beco an immediate ad-interim injunction against HUL's suit and directed Beco to file its response, with the matter listed for hearing on 21 August.
Takeaway An FMCG giant suing a small D2C challenger over a disparagement campaign risks amplifying exactly the chemical claims it's trying to shut down — the lawsuit itself is now driving more attention to Beco's ad than the ad ever got on its own.
Business Standard →Lenny Rachitsky launches a vetted job board scoped to product, engineering, design and growth roles
Lenny Rachitsky, of Lenny's Newsletter and Podcast, launched LennysJobs.com on 18 August, a free job board deliberately limited to four “builder” roles — product management, engineering, design and growth/marketing — which he says are increasingly blending together. Every listed company is vetted to filter out ghost roles and generic staffing posts, the board includes a curated “Lenny 100” list of high-talent-density companies hiring, and it embeds AI tools that let candidates rate their fit, prep for interviews and customise resumes; paid newsletter subscribers get higher AI usage limits and a proactive agent that emails them new matching roles.
Takeaway Turning a newsletter's audience into a hiring pipeline is Lenny vertically integrating distribution into product — the job board only works because years of newsletter trust already vouches for what gets listed on it.

Dalal Street snaps a seven-day losing streak as Nifty and Sensex rebound on cooling Treasury yields, even as Wall Street slides on a 9% Walmart plunge and Trump's fresh threats send crude toward $94
S&P 500 — last session, Thu 20 Aug
7,641.16−66.82 · −0.87%
Nasdaq Composite — last session, Thu 20 Aug

Sensex jumps 628 points and Nifty snaps a seven-day losing streak as cooling Treasury yields lift sentiment
The Sensex gained 628.04 points (0.82%) to close at 77,537.72 on 20 August, snapping a four-day losing run, while the Nifty 50 rose 153.55 points (0.64%) to 24,231.85, ending its longest losing streak in 11 months. All sectoral indices ended in the green except Nifty Chemicals and Nifty PSU Bank, with Nifty Media (+2%) and Nifty Realty (+1.4%) leading gains; Eternal, Kotak Mahindra Bank, Bajaj Finance, ITC and Shriram Finance were among the biggest individual Nifty gainers. The rebound tracked a recovery in global risk sentiment after the US Treasury's expanded bond-buyback programme eased pressure on long-dated yields a day earlier.
Takeaway A single US debt-management announcement was enough to snap India's worst weekly losing streak in nearly a year, underlining how directly Dalal Street's mood is now tracking Washington's bond-market plumbing rather than domestic news flow.
Business Standard →Goldman Sachs buys a ₹52.7 crore stake in Shiprocket via bulk deal, extending the stock's post-listing rally
Goldman Sachs's India equity portfolio purchased 40.24 lakh Shiprocket shares — about 0.55% of the company — at ₹131 apiece via a bulk deal on the NSE on 19 August, a transaction worth roughly ₹52.7 crore. The purchase helped extend Shiprocket's rally the following session, with shares climbing as much as 9.4% intraday to a high of ₹155.69 on 20 August, days after the logistics platform's 35% premium listing.
Takeaway A marquee institutional investor buying into a stock within days of its debut, rather than waiting for a post-listing dip, is a vote of confidence that tends to matter more to other buyers than the listing pop itself.
Inc42 →Domestic institutions buy ₹3,538 crore of Indian equities as FIIs stay net sellers on August 20
Foreign institutional investors were net sellers of ₹583.4 crore in the Indian cash market on 20 August, while domestic institutional investors bought a net ₹3,537.7 crore — more than offsetting the foreign outflow. It continues a pattern through much of 2026 in which DII buying has repeatedly cushioned the market against FII selling pressure.
Takeaway Domestic mutual fund and insurance flows, not foreign money, remain the market's real shock absorber this year — a dynamic worth watching given how much more foreign capital India still has to attract.
Trendlyne →Brent crude jumps 2.4% to $93.78 after Trump threatens “crushing” economic action against Iran
Brent crude futures rose 2.4% to close at $93.78 a barrel on 20 August, with US WTI futures up 2.7% to $86.64, after President Trump posted on Truth Social threatening Iran with the “MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY” and warned that any country doing business with Iran would face consequences; prices had risen more than 3% intraday on the threat before paring gains. Treasury Secretary Scott Bessent said he would hold a press conference the following Monday to detail the administration's plan for economic pressure on Iran.
Takeaway Oil is now trading more on a single presidential social-media post than on inventory data or OPEC+ decisions, which is exactly the kind of volatility that punishes India's import bill and the rupee without warning.
CNBC →Walmart shares sink about 9% on soft US sales growth, dragging Wall Street lower even as India rallied
US stocks fell on 20 August as Treasury yields rebounded — the 10-year back above 4.7% and the 30-year past 5.25% — reversing the prior day's buyback-driven relief; the S&P 500 lost 66.82 points (0.87%) to 7,641.16 and the Nasdaq Composite fell 263.92 points (1.0%) to 26,067.17. Walmart shares dropped roughly 9% after the retailer reported US comparable-sales growth of 2.6%, below the roughly 3.8% analysts expected, with executives saying shoppers were making “trade-offs” amid high gas prices.
Takeaway A single disappointing same-store-sales number from the country's largest retailer reads as a more reliable gauge of US consumer health than any official data release this week, and it's not a reassuring one.

Varsity principle for today: size the position, not just the conviction. Zerodha Varsity's position-sizing chapter teaches capping risk at a set share of capital per trade — a common baseline is 5% — and sizing the trade off your stop-loss distance rather than off how confident you feel. It's the discipline this week's whipsaw was practically a case study for: a seven-day losing streak followed by a single 628-point reversal is exactly the kind of volatility where oversized bets in either direction do the most damage.
