New York City’s Council puts OpenAI, Anthropic, Google and Meta executives under oath over rogue AI agents as a suspected AI-assisted breach exposes some 25,000 Shinhan Bank customers in South Korea, even as Barclays expands its Claude Code rollout bankwide, Marvell and Cisco lean further into AI infrastructure at dueling investor events, and Apple preps a multilingual expansion for its still-new AI Siri
Takeaway Today’s AI stories split into institutions finally answering for agents that have already caused real harm — a council hearing under oath, a bank breach — even as the commercial AI buildout keeps moving regardless.
NYC Council puts OpenAI, Anthropic, Google and Meta executives under oath over rogue AI agents
The New York City Council convened a rare Committee of the Whole hearing on October 5, with executives from OpenAI, Anthropic, Google and Meta testifying under oath about AI safety risks, per coverage from City & State NY and 6sqft. Council Speaker Julie Menin unveiled a package of bills that would give whistleblowers a cut of any fines the city recovers from AI companies, let New Yorkers sue developers whose systems cause harm, and require independent pre-sale validation plus an emergency kill switch for AI systems sold in the city.
Takeaway A city council, not Washington, is the one actually writing kill-switch and right-to-sue rules right now — local governments aren’t waiting for federal AI policy to catch up.
City & State NY →Suspected AI-assisted breach exposes 25,000 Shinhan Bank customers in South Korea
An attacker likely used an AI penetration-testing tool to bypass identity verification and extract customer data from a loan-recruiter service tied to South Korea’s Shinhan Bank, exposing names, phone numbers, income and borrowing limits for about 25,000 customers, per The Korea Times and Korea Herald. Security analysts found traces of an AI tool called ARTEX AI on a server linked to the attack, and smaller breaches hit other lenders the same week — KB Kookmin (119 customers) and Hana Bank (89); the Financial Supervisory Service has opened an emergency on-site inspection.
Takeaway AI tools lowering the skill needed to probe for vulnerabilities is starting to show up as a volume problem — several banks hit in the same week, not just one.
The Korea Times →Barclays scales Claude Code bankwide, targets 50% developer adoption by year-end
Barclays is extending its use of Anthropic’s Claude across software development and operations, with more than 16,000 employees already using it and roughly 120,000 emails a day now processed through Claude-based triage, per Anthropic’s own newsroom. The bank is targeting 50% of its developer population using Claude Code by the end of 2026, rising toward a majority in 2027.
Takeaway A tier-one bank naming a specific adoption target, not just running a pilot, is a concrete sign enterprise AI coding tools are past the experimental stage in regulated industries.
Anthropic →Marvell heads into today’s Investor Day on a 37% revenue surge, AI-infrastructure bets front and center
Marvell reported 37% revenue growth to $2.7 billion in its most recent quarter and is guiding to roughly $3.15 billion next quarter, ahead of its October 6 Investor Day in New York, where it’s detailing its AI-infrastructure and custom-silicon roadmap, including an expanded Google relationship it says becomes a major contributor from 2028, per Nasdaq.com.
Takeaway The AI-infrastructure capex story propping up chipmakers all year isn’t slowing — Marvell is using today’s event to extend its own guidance further out, not just defend current numbers.
Nasdaq →Cisco opens WebexOne 2026, pitching AI woven into the physical office
Cisco kicked off its multi-day WebexOne 2026 conference on October 5 in Austin, with Chief Product Officer Jeetu Patel and more than 35 customer case studies — including Meta, AMD, United Airlines and Deutsche Telekom — showcasing new AI-collaboration and “Intelligent Workplace” product features, per Cisco’s own newsroom. The event runs through October 8.
Takeaway Enterprise AI positioning is shifting from standalone chatbots to AI woven into physical offices and meeting rooms — a bet Cisco is now building its product roadmap around.
Cisco Newsroom →Apple says its rebuilt Siri adds five more languages “this October” — no firm date yet
Apple’s overhauled, Gemini-powered Siri launched in English with iOS 27 on September 14, and the company says French, Japanese, Korean, Portuguese and Spanish support follows this month, per Engadget and 9to5Mac. Apple has not confirmed an exact date within October.
Takeaway Shipping one language at a time is a notably cautious rollout next to competitors pushing simultaneous multilingual launches — worth watching whether Apple holds that pace.

Product & Business
Snapdeal parent AceVector opens at an 11.5% discount on its stock-market debut as Tata Capital’s own ₹15,500 crore IPO opens for subscription to a muted start, even as Jio Platforms wraps global investor roadshows ahead of India’s largest-ever offering and Myntra opens early access to its Big Fashion Festival a day ahead of Flipkart’s own festive sale
Takeaway Three of India’s biggest IPOs are visible at once — one already discounted on debut, one subscribing today, one still finishing its pitch — a reminder a mega-IPO wave doesn’t guarantee every listing lands well.
Snapdeal parent AceVector opens at an 11.5% discount on its stock-market debut
AceVector shares opened at ₹28.32 on the NSE and ₹28.30 on the BSE on October 5 — an 11.5% discount to the ₹32 issue price — after its ₹420 crore IPO closed 4.93-5.07 times subscribed, per the Free Press Journal and Inc42. The discount reflects market caution toward the company’s loss-making e-commerce business despite its diversified digital portfolio spanning Snapdeal, Unicommerce and Stellaro Brands.
Takeaway A moderately-subscribed book doesn’t always translate into a steady debut — investors priced in Snapdeal’s underlying losses even after a respectable subscription number.
Free Press Journal →Jio Platforms wraps global roadshows, moves toward filing its red herring prospectus
Jio Platforms has completed investor roadshows across the US, UK, Dubai, Singapore and Hong Kong, led by Akash Ambani and Isha Ambani, and is now preparing to file its red herring prospectus for what would be India’s largest-ever IPO, per the Free Press Journal and Kotak Neo. The roughly $3.8 billion fresh-issue offering could value the company near $137 billion; SEBI issued its final observations on the draft papers on August 28.
Takeaway Wrapping the roadshow and moving to the RHP is the concrete next procedural step before pricing — a sign the listing is close, even without a confirmed date yet.
Free Press Journal →Tata Capital’s ₹15,500 crore IPO opens for subscription to a muted start
Tata Capital’s IPO opened for subscription October 6-8 at a price band of ₹310-326 a share, after the company cut its target valuation to about ₹1,39,000 crore from ₹1,46,000 crore ahead of launch, per Outlook Business and Business Standard. The issue got off to a muted start, with overall bidding at roughly 21% in the first two hours — QIB demand led at 29%, retail at 19%.
Takeaway A valuation cut going into launch, followed by a slow first morning of bidding, suggests investors are pricing this IPO more cautiously than the headline size implies.
Outlook Business →Myntra opens Insider early access to its Big Fashion Festival today, ahead of Flipkart’s own sale
Myntra’s fourth annual Big Fashion Festival gives Myntra Insiders loyalty members early access starting October 6, ahead of the full sale opening October 7, with more than 23 lakh styles from 6,000-plus domestic and international brands, per Madhyamam. The company expects 8 million shoppers, with a 10% bank-offer discount plus an extra 15% off via its Kotak Mahindra co-branded card.
Takeaway Opening two days ahead of Flipkart’s Big Billion Days is a deliberate move to capture festive fashion spend before the broader e-commerce rush hits.

Sensex and Nifty snap their eight-week losing streak with a modest Monday bounce as a Reuters poll finds the RBI’s Wednesday rate call now a genuine toss-up between a hike and a hold, even as Brent eases back from last week’s $102 spike and persistent FII selling keeps this year’s outflows at a record pace
Takeaway Monday’s half-percent bounce is relief after an eight-week slide, not a turnaround, and Wednesday’s RBI call — now a real coin-flip per Reuters — is the next test for whether it holds.

Sensex and Nifty snap their eight-week losing streak with a modest Monday bounce
The Sensex closed up 472.77 points (0.66%) at 72,382.47 and the Nifty ended 133.80 points (0.6%) higher at 22,555.75 on Monday, October 5, as Indian benchmarks reopened after the Gandhi Jayanti/weekend break and snapped their four-day losing run, per Business Standard. The bounce was helped by easing crude prices and reduced bets on aggressive global rate hikes.
Takeaway A half-percent bounce after an eight-week slide reads as relief, not a trend reversal — Wednesday’s RBI call is the next real test.
Business Standard →RBI’s rate call is no longer a formality — a Reuters poll now favors a hike, not a hold
The RBI’s Monetary Policy Committee meets October 5-7, with its decision due Wednesday, and a Reuters poll found nearly 60% of surveyed economists (35 of 61) now expect a 25-basis-point hike to 5.50% — which would be the RBI’s first hike since 2023 — as retail inflation has moved back above the 4% target and global bond yields have risen. The remaining panelists still expect a hold at 5.25%, where the RBI has kept rates for five straight meetings.
Takeaway Don’t treat Wednesday’s decision as a done-deal hold — the market is genuinely split between that and the RBI’s first hike in three years.
Octagon AI →Brent eases back after last week’s spike past $102 on a third US carrier deployment
Brent crude jumped 4.4% to settle at $102.31 a barrel on October 1 after the US reportedly deployed a third aircraft carrier strike group, the USS Theodore Roosevelt, to the Middle East, joining the USS George H.W. Bush and USS George Washington, per CNBC. By Monday, crude had eased back from that peak, which Kotak Neo cited as a tailwind for Monday’s bounce in Indian equities.
Takeaway Oil remains the single biggest swing factor for both Indian equities and the RBI’s inflation math this week — a further spike would complicate Wednesday’s decision.
CNBC →Record FII selling defined the eight-week slide now in the rear-view
The eight-week losing streak that just ended was driven largely by foreign institutional investors, who have been persistent net sellers of Indian equities through much of 2026; multiple market trackers put cumulative 2026 FII outflows above the full-year 2025 total, against a backdrop of high US yields and rupee pressure, per 5paisa.
Takeaway Until FII flows actually turn, rally attempts like Monday’s are likely to stay shallow and news-driven rather than structural.
5paisa →Jio Platforms’ near-$137 billion IPO looms as the next big market event
With Jio Platforms’ global roadshows complete and the company moving toward filing its red herring prospectus, traders are increasingly treating India’s largest-ever IPO as a looming liquidity event that could reshape flows just as the market tries to build on Monday’s bounce, per the Free Press Journal and Kotak Neo.
Takeaway A listing this size would absorb significant investor cash around the same window as the RBI decision — worth watching for knock-on liquidity effects on the broader market.

Investing concept for today, via Upstox: Market Talk’s explainer on rate-decision days notes they’re among the most volatile trading days of the year, second only to Budget day — and walks through the real 2015 example of then-RBI Governor Raghuram Rajan unexpectedly holding rates at 8% instead of the widely-priced-in cut to 7.75%, which sent the Sensex surging nearly 300 points because markets move on the gap between expectation and outcome, not the decision in isolation. Heading into Wednesday’s call, a well-telegraphed hike could move prices less than a surprise hold.
