AI & Tech
OpenAI investors reportedly float a funding round that would value the company above $1.2 trillion as Anthropic says Claude now leads 26% of its own AI research and development work, while a critical pre-authentication flaw surfaces in Check Point's management servers, Google's actively exploited Chrome zero-day hits its federal patch deadline, China's Z.ai claims Nvidia-comparable economics running entirely on domestic chips, AI-security startup MIND raises $72 million, and the EU's ambition to set global AI rules runs into its own lack of leverage
Check Point discloses a critical pre-authentication flaw letting attackers run code as root
Check Point disclosed CVE-2026-91843, a CVSS 9.8 stack-overflow vulnerability in the login process of its Security Management Server, Multi-Domain Security Management Server and Log Server products, per The Hacker News. A single login request with an abnormally long username can let an unauthenticated attacker execute code as root over the network; customers with automatic updates enabled are already protected, while others need to apply the LivePatch detailed in advisory sk1000155. No in-the-wild exploitation has been confirmed yet.
Takeaway A pre-auth path straight to root on the box that manages your firewall policy is close to a worst-case flaw — the real race now is whether defenders patch faster than someone reverse-engineers it into a working exploit.
The Hacker News →Google's actively exploited Chrome zero-day hits its federal patch deadline
CVE-2026-85046, a CVSS 8.8 type-confusion flaw in Chrome's V8 engine that Google patched on 3 September in Chrome 152.0.7977.82, was added to CISA's Known Exploited Vulnerabilities catalog the next day, setting 18 September as the deadline for US federal civilian agencies to apply the fix, per The Hacker News. It's the sixth actively exploited Chrome zero-day patched so far this year.
Takeaway Six actively-exploited Chrome zero-days patched in a single year, each already being used by attackers before the fix shipped, says the browser is now some of the most contested software on the internet.
The Hacker News →OpenAI investors reportedly float a new funding round above a $1.2 trillion valuation
Investors have approached OpenAI about a fresh funding round that would value the company above $1.2 trillion, up sharply from the $852 billion valuation set in its March round that raised $122 billion, per CNBC. OpenAI is said not to be in formal talks yet, and CFO Sarah Friar told CNBC's Jim Cramer the company "still has an incredible balance sheet"; CEO Sam Altman has separately said an IPO is unlikely before 2027.
Takeaway When investors are the ones showing up with a higher number rather than the company asking for one, that's a market pricing in more confidence about OpenAI's trajectory than any earnings report could justify.
CNBC →Anthropic says Claude now leads 26% of its own AI research and development work
Anthropic's new "R&D Automation Index" found that Claude led 26% of the company's measured AI research and engineering work in August 2026, up from under 1% in February, per Engadget. Roughly 30,000 Claude agents were running research and engineering tasks at any given time that month, and of more than a billion agent decisions reviewed, an internal safety monitor intervened in roughly one out of every 47,000.
Takeaway A company whose own product is doing a quarter of the work of building its successor turns "recursive self-improvement" from a hypothetical debate into a number you can watch climb month over month.
Engadget →China's Z.ai says it serves a 320-billion-parameter model entirely on domestic chips
Z.ai published a technical account of running its open-weight GLM-5.3-Flash model, a 320-billion-parameter multimodal system, on a cluster of more than 100,000 Chinese-made AI accelerators with no Nvidia hardware involved, per Implicator.ai. The company says it reached hardware utilization and per-token cost comparable to mainstream Nvidia GPUs, though it hasn't named the chip vendor or published throughput or power figures to back that up.
Takeaway An unverified claim from the vendor itself is still worth watching — if serving a serious open model at Nvidia-like economics on domestic silicon is even close to true, US export controls lose a lot of their bite.
Implicator.ai →AI data-security startup MIND raises $72 million to stop sensitive data leaking into AI tools
MIND, which builds AI-native data loss prevention software, raised a $72 million Series B led by Crosspoint Capital Partners with existing investors YL Ventures and Paladin Capital Group, per SiliconANGLE — bringing its total funding to $112 million a year after a $30 million Series A. The company says it grew revenue 17x and its customer base 8x over the past year, and became the first data-security company accepted into Anthropic's Cyber Verification Program.
Takeaway Venture money flowing specifically into tools that stop sensitive data leaking into AI systems, rather than out of them, is a sign the industry now treats the model itself as the exfiltration risk.
SiliconANGLE →The EU's ambition to set global AI rules runs into its own lack of leverage
European Commission President Ursula von der Leyen used her State of the European Union address to position the bloc as an AI rule-setter on par with Washington and Beijing, but the EU has no dominant frontier model of its own, per Euronews. Irish MEP Michael McNamara called the pledge "lip-service," pointing to the Commission's reversal on an AI Liability Directive and its push to loosen AI Act safeguards during recent "Omnibus" negotiations before backing off again.
Takeaway Writing the rules only matters if the companies you're regulating need something from you — and right now, neither OpenAI, Anthropic nor China's labs particularly do.

Product & Business
NSE's record ₹22,562 crore IPO is 55% subscribed by Day 2 as Kissht's parent OnEMI wins board approval for an ₹832 crore raise from mutual funds and Shapoorji Pallonji backs a Tata Sons listing against Noel Tata's objections, while Rebel Foods narrows FY26 losses 16%, OTPless elevates its co-founders to CEO and COO, and D2C brand Neeman's bets its next growth leg on 500 physical stores, even as OpenAI pilots sponsored AI agents inside ChatGPT and Apple Pay looks set to finally launch in India next month via Axis Bank
NSE's record ₹22,562 crore IPO is 55% subscribed by Day 2, institutional demand still soft
India's largest-ever IPO — National Stock Exchange's ₹22,562 crore offer-for-sale, priced in a ₹1,700-1,785 band — was 55% subscribed by the close of Day 2 on 18 September, per BusinessToday. Non-institutional investors booked 1.20 times and employees 1.26 times, while retail stood at 56% and qualified institutional buyers at just 19%, with the issue closing 21 September and listing targeted for 24 September.
Takeaway Big anchor and institutional books traditionally load up in an IPO's final session, but a QIB print this soft with only days left would be the clearest sign yet the market is repricing what an exchange monopoly is worth.
BusinessToday →Kissht parent OnEMI wins board approval for an ₹832 crore raise from mutual funds, not VCs
OnEMI Technology Solutions, parent of digital lender Kissht, approved a roughly ₹832.2 crore raise via preferential issue of 2.64 crore shares at ₹314.11 apiece to 34 non-promoter investors including Axis, HDFC, Groww and Bandhan mutual funds, MIT and WhiteOak, per Entrackr. Three-quarters of the proceeds go to NBFC subsidiary Si Creva Capital to scale Kissht's lending book.
Takeaway A roster of mainstream mutual funds and an endowment, not venture capital, underwriting this raise is a template other Indian fintech lenders eyeing a public listing will likely borrow.
Entrackr →Shapoorji Pallonji backs a Tata Sons listing, setting up a proxy fight with Noel Tata
After the RBI rejected Tata Sons' bid to surrender its NBFC registration on 11 September, the board met on 17 September to weigh next steps. Second-largest shareholder Shapoorji Pallonji Group said the RBI order gives "full clarity" and backed a public listing, directly opposing Tata Trusts chairman Noel Tata, who maintains the RBI's letter "does not mention listing" and wants Tata Sons kept private, per Business Standard.
Takeaway This has moved past regulatory technicality into an open proxy fight over control of India's largest conglomerate — whichever reading of the RBI letter wins decides whether Tata Sons' opaque trust structure survives another decade.
Business Standard →Rebel Foods narrows losses 16% as cloud-kitchen revenue crosses ₹1,952 crore
Cloud-kitchen operator Rebel Foods, which runs Faasos, Behrouz Biryani and Oven Story, posted FY26 operating revenue of ₹1,951.6 crore, up 21% from ₹1,617.4 crore a year earlier, per Entrackr. Net loss narrowed 16% to ₹281.8 crore while EBITDA loss nearly halved to ₹62.4 crore; India revenue grew 18% to ₹1,667.7 crore and international revenue grew 39% to ₹283.8 crore.
Takeaway Cloud kitchens shrinking losses without shrinking growth is real progress — the harder question is whether the India business alone turns structurally profitable before investors tire of subsidizing the international arm.
Entrackr →Authentication startup OTPless elevates its co-founders to CEO and COO
Bengaluru-based OTPless elevated co-founders Satyam Nathani to CEO and Tanmay Sagar to COO as incumbent CEO Bhavik Koladiya stepped away, per Entrackr. The 12-person, BharatPe-founder-backed startup has scaled past 300 million users and ₹36 crore in annualised revenue, up 2.5 times year-on-year, and says it has been profitable for the past two quarters.
Takeaway A 12-person team running profitably at 300 million-plus users is a sharp counterpoint to the idea that AI-era products need large headcount — lean infrastructure plays are quietly out-earning bigger consumer startups on unit economics.
Entrackr →D2C footwear brand Neeman's bets its next growth leg on 500 physical stores
Neeman's is planning a 500-store offline expansion over the next three years on its way to ₹1,000 crore in revenue, per D2C Insider Pulse and YourStory's daily roundup. The digital-first footwear brand expects to close the year to March 2027 at roughly ₹350 crore in revenue, up from more than ₹185 crore the prior fiscal year.
Takeaway A "digital-first" brand choosing stores over more ad spend for its next growth leg is a quiet admission that online customer acquisition has gotten too expensive — physical retail is now the cheaper channel.
D2C Insider →OpenAI pilots advertiser-run "Sponsored Agents" inside ChatGPT
OpenAI confirmed it is testing Sponsored Agents — labeled, advertiser-run AI agents that take over a ChatGPT conversation after a user taps an ad and can hand off to the business's own site — with Wayfair and Angi as early testers, per OpenAI's own announcement. The company also opened a Shopify App Store connector for US merchants and named HubSpot its first CRM ads partner.
Takeaway Letting the advertiser's own agent carry the conversation forward, rather than OpenAI's, is a way to monetize ChatGPT without diluting trust in the model's own answers — sublet the sales pitch, keep the "helpful assistant" moment for yourself.
OpenAI →Apple Pay looks set to finally launch in India next month, via Axis Bank
Apple Pay could launch in India as soon as October, with Axis Bank as its first banking partner enabling contactless payments on Axis credit cards, per BusinessToday citing Reuters. The RBI's own website briefly listed an October 2026 launch date, and some users have already seen Axis Bank terms-and-conditions pages when trying to add cards to Apple Wallet; the first version will support only Visa and Mastercard, with no UPI.
Takeaway Launching without UPI support in the world's largest real-time payments market says Apple would rather ship a smaller version of the product now than keep waiting years for a bigger one.

TCS leads Nifty losers as the Tata Sons governance dispute wipes out roughly ₹31,000 crore of group market value even as Adani group stocks rally on a bullish Jefferies note and FIIs turn net buyers for the first time in days, while Wall Street logs a weekly loss with the 10-year Treasury yield hovering near 5% and crude extends a third day of declines on progress repairing Saudi Arabia's damaged pipeline

TCS leads Nifty losers as the Tata Sons governance dispute intensifies
TCS fell more than 3% on 18 September after Tata Sons' board voted 4-1 to reappoint N. Chandrasekaran as executive chairman for another five-year term, a move opposed by Tata Trusts, reviving fears of a governance standoff at the group's holding company, per BusinessWorld. Tata group stocks collectively lost roughly ₹31,000 crore in market value in the same session, per Upstox and Equentis.
Takeaway A boardroom power struggle at the parent company, not IT-sector fundamentals, was the single biggest swing factor for TCS's stock this week.
BusinessWorld →Adani group stocks rally as Jefferies flags ports and transmission growth
Adani Ports & SEZ jumped 4.93% to close at ₹1,824 and Adani Enterprises rose 3.31% on 18 September after Jefferies flagged capacity expansion and improving cash flows across the group, per Upstox. The brokerage said Adani Ports is tracking toward its 1-billion-tonne cargo target by 2030, implying a 16% CAGR versus its own earlier 13% estimate.
Takeaway One bullish brokerage note was enough to make Adani Ports the day's best-performing large-cap stock — a reminder of how sentiment-driven the group's valuations remain.
Upstox →FIIs turn net buyers for the first time in days as DIIs keep up their support
Foreign institutional investors bought a net ₹599.5 crore in the cash segment on 18 September, snapping a stretch of outflows, while domestic institutional investors bought a net ₹1,019.7 crore the same day, per 5paisa's FII-DII tracker. For the month, FIIs remain net sellers of roughly ₹7,041 crore while DIIs have infused about ₹36,219 crore.
Takeaway Domestic funds have been the market's main shock absorber all September — FIIs turning buyers for even one session, however small, is worth watching for whether that cushion is finally easing.
5paisa →Wall Street logs a weekly loss as the 10-year Treasury yield hovers near 5%
US stocks were mixed on 18 September — the S&P 500 rose 0.17% to 7,650.50 and the Nasdaq gained 0.39% to 26,522.55, while the Dow slipped 0.18% — as investors weighed the Fed's rate hike to 3.75%-4% against a 10-year Treasury yield that briefly touched 5.012% earlier in the week, its highest since 2007, per Yahoo Finance. Both the S&P and the Dow still ended the week lower even after Friday's gains.
Takeaway Calm daily index moves are masking a real tightening in financial conditions as long-term yields grind higher — the weekly scorecard tells a different story than any single day's close.
Yahoo Finance →Crude extends a third day of declines as Saudi Arabia's pipeline repair progresses
Brent and WTI both eased for a third straight session on 18 September as traders weighed Saudi Arabia's progress restoring its attacked East-West pipeline against renewed Houthi-Saudi conflict risk, per CNBC. WTI traded near $100-101 a barrel and Brent near $102-104, still elevated versus pre-conflict levels tied to the broader Strait of Hormuz tensions.
Takeaway Oil is cooling from crisis highs but remains one headline away from reversing — that keeps inflation risk alive for both the Fed and the RBI even as prices ease.

Zerodha Varsity principle for today: With the Fed's rate hike and the 10-year Treasury yield brushing 5% dominating this week's market narrative, Varsity's chapter on direct bond investing is worth the read. The core idea: bond prices and interest rates move inversely, so when rates rise, existing lower-coupon bonds fall in price because newer bonds now offer better rates — exactly why rate-sensitive stocks and bonds alike came under pressure this week. What matters isn't a bond's coupon rate but its Yield to Maturity: the real return an investor earns buying at today's price and holding to maturity, which rises automatically as the bond's market price falls.
