AI & Tech
Anthropic overtakes OpenAI on revenue as AI funding surges and safety scrutiny intensifies
AI inference-chip startup Etched raises $700M, valuation doubles to $21B in under a month
Etched, which builds server racks with chips designed specifically for AI inference, closed a $700 million Series D led by Jane Street on 18 August at a $21 billion valuation — more than double the $10.3 billion mark from its Series C just weeks earlier in July, and up from $5 billion last December. The company says it has booked over $1 billion in orders and needed just 44 days to go from receiving test chips from TSMC to running inference workloads, versus a typical six months or more.
Takeaway A pure inference-chip startup doubling its valuation in under a month suggests investors now see serving AI models cheaply, not just training them, as the next infrastructure bottleneck worth funding.
TechCrunch →OpenAI launches ChatGPT for Teens with content limits and parental controls
OpenAI rolled out a dedicated ChatGPT experience for 13-to-17-year-olds on 18 August, adding stricter restrictions around topics like self-harm and romantic or sexual conversations, plus optional parental controls. The teen version also introduces a “Study Mode” that offers guiding questions and step-by-step support instead of direct answers, with scheduled “Study Hours” parents or teens can set.
Takeaway Building the launch around study habits rather than only crisis-content filters suggests OpenAI is trying to get ahead of the “AI as tutor vs. AI as cheat tool” debate before schools or regulators force the issue.
TechCrunch →Meta's landmark youth-harm trial opens in Oakland federal court
Opening arguments began 18 August in Oakland before Chief Judge Yvonne Gonzalez Rogers in a case brought by a coalition of state attorneys general accusing Meta of designing Facebook and Instagram features to addict children and misleading the public about platform safety. Meta has said potential damages could reach $1.4 trillion — close to its roughly $1.5 trillion market cap — with the trial expected to run six to eight weeks and CEO Mark Zuckerberg and Instagram head Adam Mosseri both expected to testify.
Takeaway With damages estimated near Meta's entire market value, this trial functions less like ordinary litigation risk and more like a stress test of the engagement-optimized feed as a business model.
NPR →Reddit starts turning text posts into AI-narrated videos
Reddit began testing a “Play” mode that converts selected text posts and top comments into short videos with AI-generated voiceover and synced on-screen text, labelled “Real conversation voiced by AI.” The web version launched 17 August with iOS and Android following a day later, limited for now to select English-language communities that Reddit curates by hand — a move CEO Steve Huffman previewed on the company's July earnings call.
Takeaway Reddit competing with the third-party TikTok accounts that already repackage its threads into narrated video suggests text-first platforms are running out of room to avoid short video on their own terms.
TechRepublic →Hacker claims to have stolen 3.6 million employee records from McDonald's, Vodafone, TCS and others via Azure
A threat actor using the handle “TheHatman” has been posting internal employee directories on cybercrime forums, claiming they were pulled from victim companies' Azure/Entra tenants using compromised credentials rather than a platform-wide flaw. Reported figures include roughly 1.7 million records from McDonald's, about 800,000 from TCS, 425,000 from Vodafone and 250,000 from HCL Technologies, with researchers pointing to infostealer malware or weak MFA enforcement as the likely cause rather than a Microsoft vulnerability.
Takeaway This is a reminder that the biggest practical AI-adjacent security risk right now isn't a novel model attack — it's old-fashioned credential theft against the identity systems everything else depends on.
BleepingComputer →Anthropic's revenue run rate surges to $65 billion, overtaking OpenAI's in Q2
Anthropic told investors its annualized revenue run rate surpassed $65 billion at the end of July, up from $47 billion in May, with its roughly $11.5 billion in Q2 revenue topping OpenAI's reported $6.7 billion for the same quarter — the first time it has done so. Coverage attributes part of the gap to continued strength in Anthropic's Claude Code coding tool alongside slowing ChatGPT growth, and notes Anthropic posted a positive operating result for the quarter.
Takeaway A coding-tool-driven revenue lead over the company that popularized consumer AI suggests the stickiest near-term AI revenue isn't chatbots — it's developers who don't easily switch once a workflow is built around one tool.

Product & Business
Shiprocket lists as India's startup funding spans fintech to health-tech, and Silicon Valley faces its own reckonings
Razorpay launches Vulcan, its own AI foundation model for payments
Razorpay launched Vulcan, which it describes as India's first transformer-based foundation model built specifically for payments, developed with Nvidia for training and AWS SageMaker for deployment. Co-founder Harshil Mathur said the model was trained on roughly 3 trillion data points across 4 billion payments and reads about 3,000 signals per transaction to handle routing, fraud detection and checkout in one model instead of several; in beta across more than 51,000 businesses, Razorpay reported an 8–10% improvement in payment success rates and 8x more international card fraud caught.
Takeaway A payments processor building its own foundation model rather than buying fraud and routing tools off the shelf signals that infrastructure-heavy fintechs now see proprietary AI as a moat, not just a feature.
Business Standard →AI-lending platform Rezolv raises $12.5M Series A, valuation up 4x in a year
Rezolv, an AI-native lending-tech platform founded in 2024 by former Kissht executives Karan Mehta and Sonali Jindal, raised a $12.5 million Series A led by Norwest Venture Partners, with Vertex Ventures SE Asia & India and existing investor 3one4 Capital also participating. The round values the company at $51.2 million, roughly four times its $12.8 million post-seed valuation a year earlier; Rezolv works with more than 22 banks and NBFCs including AU Small Finance Bank and ICICI Bank, and says its tools have improved collection and resolution rates by 35%.
Takeaway A fourfold valuation jump for a debt-collection AI startup shows investors are pricing “AI applied to unglamorous back-office lending” as aggressively as they price consumer-facing AI.
DealStreetAsia →Shiprocket debuts on NSE and BSE today after its IPO was subscribed nearly 100 times
Shiprocket's ₹1,617 crore IPO — priced between ₹92 and ₹97 a share — closed subscribed 99.38 times overall, with qualified institutional buyers alone bidding for 122.8 times their portion, when bidding wrapped on 14 August. Shares are scheduled to list on NSE and BSE today, 19 August; grey-market trading ahead of listing pointed to an opening price of roughly ₹130, a premium of more than 30% over the issue price, though that figure is a pre-listing estimate rather than a confirmed close.
Takeaway A near-100x subscribed logistics-tech IPO is a vote of confidence in India's e-commerce fulfilment layer, not just in flashier consumer-app listings.
Business Standard →DeHaat's consumer food spin-off Honest Farms raises ₹35 crore pre-Series A
Honest Farms, the pesticide-free food brand spun off from agri-tech company DeHaat, raised ₹35 crore in a pre-Series A round led by OTP Ventures, with Sadev Capital and Maiuni Ventures also participating. DeHaat co-founder Adarsh J Srivastava will lead the brand as CEO; it currently sells more than 100 products across 3,000-plus retail stores in over 120 cities plus quick-commerce and e-commerce channels, and aims to grow annual recurring revenue to ₹200 crore and reach 10,000-plus stores within 12–18 months.
Takeaway A farm-tech company spinning off and separately funding a branded consumer label suggests it sees more near-term value in owning the retail shelf than staying a pure B2B supply-chain business.
Entrackr →Child-development startup Lissun raises ₹48 crore Series A, backed by Zerodha's Rainmatter
Lissun, a Gurugram-based startup running development centres for children with special needs and developmental delays under its “Sunshine by LISSUN” brand, raised ₹48 crore in a Series A round led by Colossa Ventures, with Physis Capital, RPSG Capital Ventures, IvyCap Ventures and Zerodha's Rainmatter Capital among the participants. The company plans to use the funds to expand its centre network and build AI-led diagnostic and care tools on its own clinical data.
Takeaway Rainmatter's participation is notable — India's largest retail-broking-linked fund is quietly building a healthcare bench outside the fintech sector it's usually associated with.
StartupTalky →Geospatial-data startup NeoGeo raises $20 million Series A to expand overseas
NeoGeo, a Gurugram-based geospatial technology company founded in 2019, raised $20 million in a Series A round led by Neev II Fund and Aavishkaar Capital. The company builds GIS platforms for urban governance, infrastructure and natural-resource management, has completed more than 200 projects, mapped over 5 lakh square kilometres and manages 550-plus positioning-reference stations; it plans to use the funds for product expansion and entry into Middle East and Americas markets.
Takeaway A sizable Series A for a mapping-infrastructure company points to urban-governance data becoming a fundable category of its own, rather than a feature bundled into logistics or real-estate platforms.
Business Standard →OpenAI's design lead: designers feel miserable not because AI is replacing them, but because their role is undefined
Ian Silber, OpenAI's head of product design, told Lenny Rachitsky that despite surveys showing designers as tech's most anxious cohort, “this is the best time in history to be a designer” — and that the real problem is role ambiguity, not job loss. He argues engineers absorbed a 10–100x productivity jump from AI while design workflows haven't compressed the same way, leaving the job shifting from producing artifacts to directing a generator: steering, evaluating and owning user understanding.
Takeaway If engineering's AI-driven productivity leap already reset how much one engineer is expected to ship, design teams still sized on the old designer-per-engineer ratio are likely to feel that mismatch first.
Lenny's Newsletter →DOJ reportedly investigating Andreessen Horowitz over board seats at rival AI and data companies
Bloomberg reported on 17 August that the US Department of Justice has spent nearly a year investigating whether Andreessen Horowitz's board seats at Databricks (held by co-founder Ben Horowitz) and Fivetran (held by partner Martin Casado) violate a Clayton Act provision that generally bars one person from sitting on the boards of competing companies. The DOJ has not decided whether to pursue enforcement, and other VCs have reportedly been surprised by the probe, in part because a16z's founders originally said the firm wouldn't take board seats at all.
Takeaway As VCs hold increasingly concentrated stakes and board seats across an entire AI and data stack, this probe tests whether decades-old antitrust board-interlock rules still fit how venture ownership actually works today.

Crude spike and Middle East tensions push Sensex to a third straight losing session
The Sensex fell 492.70 points (0.63%) on 18 August as Brent crude rose to about $91 a barrel and the temporary US-Iran ceasefire on Strait of Hormuz shipping lapsed, reviving fears over Middle East supply disruption; the Nifty 50 closed lower for a sixth straight session. IT and realty stocks led the declines while healthcare and auto names outperformed, and the rupee weakened slightly against the dollar alongside rising domestic bond yields.
Takeaway A losing streak this long, with IT leading the declines, suggests foreign-flow-sensitive, dollar-earning sectors are absorbing both the oil shock and a weaker rupee at the same time.
Business Standard →30-year US Treasury yield hits a 19-year high, triggering a chip-stock selloff
The 30-year US Treasury yield climbed to roughly 5.31–5.33% on 18 August, its highest level since 2007, driven by heavy government debt issuance and persistent tariff- and energy-driven inflation; the 10-year yield hovered near 4.7%. Semiconductor and AI-infrastructure names were hit hardest — Nvidia fell about 2.3%, Micron 6–7%, AMD 4.3% and the Philadelphia Semiconductor Index around 3.7% — dragging the Nasdaq Composite down 1.33% on the day.
Takeaway Because AI-infrastructure stocks are priced on distant future earnings, rising long-term yields make the entire buildout more expensive to finance — which is why chipmakers, not the broader market, took the sharpest hit.
Kiplinger →Milky Mist Dairy shares jump nearly 30% on market debut
Temasek-backed Milky Mist Dairy Food listed on the NSE and BSE on 18 August at ₹165 a share, an 18% premium over its ₹140 issue price, after its ₹1,553 crore IPO was subscribed 56.12 times, with qualified institutional buyers bidding for 155.83 times their portion. The stock later touched an intraday high of ₹181.50, a gain of nearly 30% over the issue price.
Takeaway A 56x-subscribed IPO that keeps climbing well past its listing premium points to strong post-listing retail buying, not just pre-listing institutional demand — a pattern worth watching if it repeats across this IPO wave.
India Infoline →Nifty 50 companies post their fastest profit growth in 10 quarters
Nifty 50 companies reported 18% year-on-year profit growth in the June quarter (Q1 FY27), the fastest pace in 10 quarters, according to a Motilal Oswal report, with sales up 18% and EBITDA up 15% excluding oil marketing companies. Just five companies — ONGC, Hindalco, Reliance, JSW Steel and Bharti Airtel — accounted for 60% of the total earnings increase, while mid-cap earnings rose 23%, an 11-quarter high.
Takeaway With five stocks driving 60% of the earnings beat, the “broad-based recovery” headline masks a fairly concentrated rally — a stumble at any one of those five could disproportionately dent next quarter's earnings narrative.

Varsity principle for today: position sizing — the size of a loss matters more than how often you lose. Recovering from a big loss is mathematically harder than it feels: a 50% loss requires a 100% gain just to break even. Zerodha Varsity's position-sizing chapter argues that staying in the game long enough, through disciplined bet-sizing on every trade, matters more to long-term survival than any single winning trade.
