Nvidia pays $6 billion to license AI coding startup Poolside as Broadcom seeks up to $80 billion to bankroll Anthropic's chip buildout, while a perfect-10 Entra ID flaw already under attack forces Microsoft into emergency mode
Nvidia strikes a $6 billion licensing deal with AI coding startup Poolside, plus a $1 billion investment at a $12 billion valuation
Nvidia agreed on 20 August to a non-exclusive $6 billion license for Poolside's “Model Factory” — the system behind its Laguna family of open-weight coding models — alongside a separate $1 billion investment in Poolside at a $12 billion pre-money valuation, according to a letter to investors reported by Newcomer and confirmed by Bloomberg. About 109 Poolside employees who worked on Laguna received job offers from Nvidia as part of the arrangement. Poolside's three co-founders, including Jason Warner and Eiso Kant, are staying on and the company will keep operating independently — unlike Meta's Scale AI deal or Google's Character AI deal, no leadership is departing. The license itself is non-exclusive, meaning Poolside can still sell the same technology to other buyers.
Takeaway Structuring this as a licence-plus-minority-stake rather than an acquihire lets Nvidia buy influence over a model-building startup's output without triggering the antitrust scrutiny or leadership exodus that soured Meta's Scale AI and Google's Character AI deals.
The Next Web →Nevada approves up to 8,000 robotaxis for Tesla, Uber and Waymo across Las Vegas and Clark County
The Nevada Transportation Authority unanimously approved commercial robotaxi permits covering all of Clark County on 20 August, replacing an earlier interim order that had capped Tesla at just 10 vehicles. Tesla was authorized for up to 5,000 robotaxis, Waymo for up to 1,000, and Uber will field vehicles through partnerships with Motional and Zoox. Tesla's Cybercab chief engineer Eric Early told the hearing the 5,000 figure “has always been a ceiling for us,” adding the company would be “extremely happy and satisfied” to reach 2,500 vehicles within the next year.
Takeaway The gap between the 8,000-vehicle ceiling regulators just approved and the fleet size Tesla itself says it can realistically field next year shows permitting is now running ahead of the actual robotaxi supply chain, not behind it.
TechCrunch →Broadcom seeks up to $80 billion in off-balance-sheet debt to bankroll Anthropic's AI chip buildout
Broadcom is in talks with lenders to raise $70–80 billion in debt — with some reports putting the ceiling as high as $100 billion — to finance AI chip purchases for Anthropic and other customers, Bloomberg and CNBC reported on 21 August. The structure under discussion includes a senior tranche of roughly $45–70 billion and a junior tranche of around $30–35 billion, with Blackstone and Apollo Global Management among the investors in talks to participate. Under the arrangement, Anthropic wouldn't buy the chips outright — investors would finance the purchase and lease the hardware to the company instead. It extends a partnership Broadcom, Apollo and Blackstone unveiled in June, which committed $35 billion toward Anthropic's compute buildout with a target of delivering more than 20 gigawatts of compute to top AI labs by 2028.
Takeaway AI infrastructure financing is migrating off corporate balance sheets and into special-purpose vehicles that lease hardware back to the AI lab — exactly the kind of “shadow credit” structure bond investors have started flagging as a risk if AI demand ever cools faster than the debt gets repaid.
CNBC →Google rolls out a “Preferred Sources” button that publishers can embed to fight AI-driven traffic losses
Google released an embeddable “Preferred Sources” button on 20 August that publishers can place on their own pages; when a reader clicks it, the site is added as a preferred source across Google Search, Discover and Google News, and the reader is returned to where they left off. Google says people have already selected more than 600,000 unique sources since the button went live, and that internal studies found readers are twice as likely to click through to a source they've marked as preferred. It follows Google's earlier rollout of Preferred Sources inside AI Mode and AI Overviews in May 2026; Google also said it will let users customize their Discover feed via a three-dot menu within days.
Takeaway This is a self-help tool, not compensation — it asks publishers to do the marketing work of getting readers to click an embed, to claw back some of the clicks that Google's own AI Overviews are the biggest reason they lost in the first place.
TechCrunch →Samsung raises advanced foundry chip prices by up to 15% as AI demand fills its 4nm lines
Samsung raised prices on new orders for its 4-nanometre SF4 process by 10–15% for US and Chinese customers and 5–10% for Taiwanese customers, with its 5nm SF5 process also rising 10–15% and even its older 8nm line increasing by nearly 10%, Reuters reported on 19 August. The increases took effect in July. Samsung's SF4 line at its Pyeongtaek, South Korea facility has run at full capacity since late 2025, as surging AI chip demand has pushed TSMC's leading-edge capacity to saturation and sent some customers — reportedly including Google, for chips on the SF4 process — toward Samsung as an alternative.
Takeaway The AI boom's chip bottleneck is visibly rewriting the foundry pecking order: Samsung is turning TSMC's overflow demand into its first real pricing power in years, not through better technology but simply because TSMC is sold out.
Tom's Hardware →Microsoft patches a perfect-10 Entra ID flaw that was already being exploited before disclosure
Microsoft disclosed CVE-2026-69836 on 21 August, a maximum-severity (CVSS 10.0) vulnerability in Entra ID caused by unsafe deserialization of untrusted data, which let unauthenticated attackers remotely execute code with no user interaction required. Discovered by Microsoft principal security engineer Robert Fitzpatrick, the flaw was already being exploited in the wild before Microsoft disclosed it, though the company hasn't said who was behind the attacks or how widespread they were. Because Entra ID is a Microsoft-operated cloud service, the company was able to fully mitigate the vulnerability on its own infrastructure — “there is no action for users of this service to take,” Microsoft's advisory states.
Takeaway A perfect 10.0 score in the identity layer underneath most enterprise Microsoft 365 and Azure tenants — one that was already under attack before anyone outside Microsoft knew it existed — is a reminder that cloud identity providers, not endpoints, are now the highest-value single point of failure in corporate security.
The Register →Anthropic's annualized revenue tops $65 billion as it prepares an IPO expected to rival SpaceX's record debut
Anthropic told investors its annualized revenue run rate climbed to roughly $65 billion in July 2026, up from about $9 billion at the end of 2025 and $47 billion in May, CNBC and Bloomberg reported on 17 August. The company's Q2 revenue alone exceeded $11.5 billion, and investors reportedly expect it to finish 2026 between $100–120 billion in run rate. Bloomberg separately reported on 20 August that Anthropic now expects its IPO — which could be filed publicly as soon as the end of August — to match or exceed the roughly $1.77 trillion size of SpaceX's record-setting June 2026 debut, with some investor valuation expectations reaching $2 trillion or higher. For comparison, OpenAI's annualized revenue was reported at roughly $40 billion as of the end of July.
Takeaway Anthropic pulling ahead of OpenAI on revenue while sizing its IPO to rival SpaceX suggests the “AI leader” narrative in public markets may end up being decided by enterprise and coding-agent revenue, not by which lab has the most-hyped consumer chatbot.
CNBC →OpenAI previews a safety system designed to catch misuse without breaking its zero-data-retention promise
OpenAI announced Private Safety Processing (PSP) on 19 August, a system that lets automated processes detect misuse patterns across related API interactions while preserving Zero Data Retention guarantees for eligible enterprise customers. Under PSP, flagged activity produces only a narrowly scoped signal — the category of concerning activity — rather than exposing raw customer content to OpenAI staff, and stored content is encrypted with customer-controlled keys OpenAI personnel cannot access; the one carve-out is suspected CSAM imagery, which remains subject to mandatory review and reporting under US law. OpenAI says PSP is being tested with a small group of early customers now, with broader rollout and a technical white paper planned for September.
Takeaway This directly answers the tension in Anthropic's own zero-retention-plus-monitoring pitch to enterprises — “can you get compliance-grade privacy without losing abuse detection” has become a genuine competitive battleground between the two labs, not just a policy footnote.

Sachin Bansal's Navi takes its first outside money and Stripe pays $8 billion for OpenRouter, as New York overtakes Silicon Valley in tech jobs and Zepto, Atomberg, Augmont and Temple all queue up for India's IPO market
Sachin Bansal's Navi takes its first-ever outside capital with a $100 million investment from Prosus
Navi Limited, the fintech founded by Flipkart co-founder Sachin Bansal, is getting a proposed $100 million investment from Dutch investor Prosus — the first institutional capital the company has taken after running largely on Bansal's own money since 2018, TechCrunch and YourStory reported on 19 August. The deal values Navi at roughly $1.3 billion, and Prosus said it reflects confidence in Navi's “business model, execution capabilities and long-term growth potential.” Navi Finserv's lending book has crossed ₹130 billion (about $1.4 billion) in assets under management, and the company is separately said to be preparing an IPO targeting around ₹3,000 crore (about $314 million). The investment is subject to closing conditions including Competition Commission of India clearance.
Takeaway After eight years of deliberately avoiding VCs, taking outside money right before an IPO isn't about needing cash — it's about buying a credible anchor valuation to point to when pricing the public offering.
TechCrunch →Smart-appliance maker Atomberg files for a ₹450 crore IPO as early backers line up partial exits
Atomberg, the smart-fan and appliance maker founded in 2012 by Manoj Meena and Sibabrata Das, filed its draft red herring prospectus with SEBI on 21 August for a ₹450 crore fresh issue plus an offer-for-sale of up to 7.65 crore shares. A91 Partners, the company's largest shareholder at 21%, is offloading 3.77 crore shares, with Temasek-backed V-Sciences selling 1.22 crore shares and Jungle Ventures about 99 lakh shares. Of the fresh proceeds, ₹150 crore is earmarked for brand and performance marketing and ₹100 crore for R&D.
Takeaway A ₹100 crore R&D line item inside a fan-and-appliance IPO shows the “smart appliance” category is now competing on IoT and software differentiation, not just energy-efficiency marketing.
Entrackr →Gold and silver platform Augmont Enterprises' ₹825 crore IPO gets subscribed 2.74 times on day one
Augmont Enterprises, which runs an integrated gold and silver platform across 24 Indian states through its Augmont SPOT (business-facing) and Gold For All (consumer-facing) arms, opened its ₹825 crore IPO on 21 August at a price band of ₹750–788 per share — a ₹620 crore fresh issue plus a ₹205 crore offer-for-sale. The issue was subscribed 2.74 times on its opening day, Business Standard reported, with retail investors moving fastest to fill their quota. Allotment is expected 27 August, with listing tentatively set for 31 August.
Takeaway Strong retail demand for a gold-and-silver infrastructure platform, rather than the metal itself, shows investors betting on India's bullion trade digitizing rather than on where the gold price goes next.
Business Standard →Zepto pushes its IPO to early-to-mid 2027 after investors balk at its $7 billion private valuation
Zepto now aims to list between February and May 2027, having originally targeted a 2026 listing, after institutional investors valued the quick-commerce company well below its roughly $7 billion private valuation over profitability and cash-burn concerns, Forbes India and Inc42 reported this week. Co-founder and CEO Aadit Palicha told employees at a 31 July town hall that the company intends to go public once its financial performance improves and market conditions support a stronger valuation; the company closed a pre-IPO private placement of more than ₹1,000 crore (about $105 million) on 1 August.
Takeaway Choosing to wait a year rather than list at a lower valuation is a bet that Zepto's numbers will improve faster than quick-commerce sentiment will sour further — a bet its rivals' continued cash burn makes riskier by the month.
Inc42 →Deepinder Goyal's health-wearable startup Temple seeks a $500 million valuation, up from $190 million in February
Temple, the metabolic-health wearable startup Deepinder Goyal launched after stepping down as Eternal CEO, is gearing up for a fresh funding round at a $500 million valuation — more than 2.5 times the $190 million valuation it raised $54 million at in February from Peak XV Partners, Steadview Capital, Vy Capital and Info Edge, StartupTalky reported on 21 August. The company has also run a partial ESOP buyback at a $375 million valuation to reward early employees. Temple's first product, a forehead-worn device that measures the body's metabolic state in real time, is set to launch soon priced between ₹75,000 and ₹80,000.
Takeaway A valuation jump this steep before the flagship product has even shipped is a bet on Goyal's own track record as much as on the wearable itself — investors are pricing in a repeat of Zomato's execution, not evidence of Temple's yet.
StartupTalky →IPO-bound edtech Imarticus Learning acquires Singapore's BELLS Institute for ₹800 crore
Imarticus Learning acquired Singapore-based BELLS Institute of Higher Learning for approximately ₹800 crore in its first-ever international acquisition, positioning Singapore as the Mumbai-based edtech company's regional hub for Southeast Asia. The deal comes as Imarticus prepares to file its draft red herring prospectus within four to five months for a planned ₹1,000 crore IPO, aiming to deepen its enterprise learning, AI, data-analytics and workforce-development capabilities in the region.
Takeaway Buying international reach before filing IPO paperwork, rather than after, lets Imarticus tell public-market investors a growth story that isn't just “more Indian students” — it's betting global scale is worth more to its valuation than a cleaner balance sheet.
Inc42 →Stripe agrees to acquire AI model-routing startup OpenRouter for more than $8 billion
Stripe agreed to acquire OpenRouter — a routing layer giving developers one API to reach more than 400 AI models across dozens of providers, with automatic failover and per-token pricing — for more than $8 billion in cash and stock, Stripe confirmed on its own newsroom around 21 August, after Axios first reported the figure on 17 August. OpenRouter takes roughly a 5% cut of inference spend and claims 8–10 million developers routing tens of trillions of tokens weekly. The price is more than five times the $1.3 billion valuation OpenRouter fetched just three months earlier in its May 2026 Series B, backed by CapitalG, a16z and Menlo Ventures.
Takeaway Stripe is trying to become the toll booth for AI model traffic the same way it became the toll booth for internet payments — except this market doesn't yet bill per transaction the way payments infrastructure does, so the multiple is a bet the billing model catches up.
Stripe Newsroom →New York overtakes San Francisco as the top US tech talent market for the first time in 13 years
CBRE's 2026 report found New York's metro tech workforce reached 394,300 jobs versus the Bay Area's 375,730 — the first time New York has led in the 13 years CBRE has tracked the metric, the firm reported on 21 August. Finance added 90,530 tech jobs since 2022 while the core tech industry cut 21,262 over the same period; AI-specific roles grew 45% year-over-year nationally, with both cities adding more than 20,000 AI jobs since mid-2025. San Francisco still leads CBRE's broader weighted index (81.98 versus New York's 70.38), which factors in R&D investment and talent-pipeline depth, not just raw headcount.
Takeaway Wall Street is now a bigger driver of AI hiring growth than the tech industry itself — the center of gravity for AI talent may be following the money into finance, not staying anchored in Silicon Valley.

Dalal Street ends flat after a whipsaw week as Bitcoin's 22% weekly surge outshines equities, even as Brent crude tops $94 on Trump's looming “economic D-Day” against Iran

Sensex and Nifty end nearly flat as Dalal Street pauses after last week's whipsaw
The Sensex inched up just 3.11 points (0.00%) to close at 77,540.83 on 21 August, while the Nifty 50 rose 20.15 points (0.08%) to 24,252.00, in a volatile, rangebound session where gains in metal and realty stocks offset selling in IT, FMCG, auto and pharma. The near-flat finish follows a week that saw a seven-day losing streak snap on Thursday with a 628-point Sensex rally, itself a reversal of the prior week's slide — leaving the index essentially where it stood days ago despite the intervening swings.
Takeaway A week that included a seven-day losing streak, a single-day 628-point rally, and a virtual dead stop is exactly the kind of chop where traders sizing positions off conviction rather than risk tend to get whipsawed the hardest.
HDFC Sky →Domestic institutions buy ₹2,124 crore of Indian equities as FIIs stay net sellers
Foreign institutional investors were net sellers of ₹542.70 crore in the Indian cash market on 21 August, while domestic institutional investors bought a net ₹2,124.10 crore — nearly four times the size of 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 tops $94 a barrel, its highest since July, as Trump's “economic D-Day” against Iran looms
Brent crude rose to $94.24 a barrel on 21 August, its highest level since July and on track for a second consecutive weekly gain of around 6%, as markets braced for new US measures aimed at isolating Iran's economy. Treasury Secretary Scott Bessent said details of the plan — which President Trump has described as an “economic D-Day” — would be announced the following Monday, with the measures potentially affecting countries that continue trading with Tehran, including China, the largest buyer of Iranian crude.
Takeaway Oil is trading more on the timing of a single press conference than on inventory data or OPEC+ decisions, which is exactly the kind of volatility that punishes India's import bill and the rupee without much warning.
Trading Economics →Bitcoin surges 22% for the week, its best run since March 2024, lifting crypto-linked stocks along with it
Bitcoin settled above $77,000 on 21 August, up 22% for the week — its best five-day performance since March 2024 — after the US Treasury's announcement of expanded long-dated bond buybacks boosted liquidity and bitcoin ETFs pulled in $1.6 billion of inflows over the week, CNBC reported. Crypto-linked equities rode the wave: Strategy gained nearly 12%, while Coinbase, Circle Internet Group and BitMine Immersion Technologies each rose roughly 10%. Coinbase CEO Brian Armstrong also publicly endorsed the bipartisan Clarity Act on CBS News, arguing the crypto-market-structure legislation would protect consumers and prevent another FTX-style collapse.
Takeaway Risk appetite is roaring back in crypto even as equities stay cautious — a reminder that bitcoin's rallies are now driven more by macro liquidity signals like Treasury buybacks than by anything happening inside the crypto industry itself.
CNBC →Tempsens Instruments' ₹650 crore IPO draws strong demand with grey-market premium near 58%
Tempsens Instruments' ₹650 crore IPO, priced in a band of ₹285–300 per share, opened for subscription on 20 August and runs through 24 August ahead of a 28 August listing. Its grey-market premium was running around ₹175 a share — roughly 58% over the upper end of the price band — as of 19 August, implying an estimated listing price near ₹475 if the premium holds.
Takeaway IPO street remains hot even as the secondary market stays flat — investors are still willing to pay up for a fresh listing story while showing far less enthusiasm for stocks already trading.

Varsity principle for today: accept uncertainty as the cost of being in the market. Zerodha Varsity's risk-management chapter argues markets never offer perfect knowledge, and professional trading requires accepting that losses and drawdowns are unavoidable rather than something to fight — traders who can't accept a loss tend to hold on too long hoping to avoid realizing it. It's a fitting frame for a week that swung from a seven-day losing streak to a 628-point rally to a near-dead-flat close: the discipline isn't predicting which day you get, it's surviving all three.
