News Today, Oct 20: Jio IPO, Microsoft Agents, Amazon Nuclear

Published: October 20, 2026 | Category: AI | By Mahesh

Tuesday, October 20, 2026 brought a mix of a record IPO about to open, agent security from Microsoft, open models from Nvidia and a nuclear power deal from Amazon. Here is what happened across IT and the wider technology world.

Microsoft launches Guardian Agents to watch AI agents it says cannot be trusted

Microsoft Corp. (NASDAQ: MSFT) introduced new security features on Monday, led by Guardian Agents, which monitor the AI agents a company uses [1]. Guardian Agents is part of Project Perception, a product Microsoft introduced in June [1]. Hayete Gallot, Microsoft's security business chief, wrote that frontier models, regardless of origin, cannot be trusted, and said the reason is unpredictability: the models are trained to achieve tasks, not to follow organisational norms or judgment [1]. Microsoft Defender now has an agent detection feature that can find up to 60 types of agents that employees bring into the workplace, including Claude Code, Codex and OpenClaw [1]. New controls also limit agents' access to data and systems, adjust their permissions to the task and require human approval when an agent appears to be making risky decisions [1].

Chief executive Satya Nadella wrote earlier this month on his blog that enterprises should stop relying on model providers' assurances and keep systems the AI labs do not control to watch and control the agents they launch [1]. TechCrunch calls the move both surprising and self-serving, since Microsoft wants enterprises to buy agent security from it rather than from the labs whose agents are being watched, though it adds that the logic is sound because monitors should be separate from suppliers, as auditors are from the organisations they audit [1]. Microsoft is also an inaugural member of Nvidia's Open Agent Safety Platform, which more than 100 other companies support and which isolates agents in secure environments and can stop their behaviour through hardware, something like a kill switch [1].

"We simply can't outsource responsibility for what intelligence does on our behalf."

Nvidia releases open Nemotron 3.5 models for enterprise agents and AI PCs

Nvidia Corp. (NASDAQ: NVDA) announced Nemotron 3.5 Super VL, a 120-billion-parameter open-weight model for enterprise agents that it says matches the accuracy of its larger Nemotron 3 Ultra on instruction-following and tool-use tasks [2]. It also released two lighter Bolt models meant to run locally on AI PCs with the RTX Spark chip and on DGX Spark workstations: Bolt 74B-A9B for local agent tasks such as multistep reasoning and web browsing, and a smaller E4B for conversational agents [2]. Super VL and Bolt 74B-A9B are available now, with E4B due later this month [2]. Nvidia claims Super VL finishes tasks faster than competing models from Anthropic and OpenAI once post-trained on specific agentic tasks, and it lists Skydance, EY, Ramp, CrowdStrike, Perplexity and Salesforce as users [2]. Those are Nvidia's own claims, and TechCrunch notes that such claims are standard at model launches [2].

Kari Briski, Nvidia's vice president of open models and software, said organisations can post-train Super VL on their own data and run it on their own infrastructure [2]. TechCrunch frames the launch as Nvidia leaning into companies that want to run their own open models while the proprietary labs, which are both Nvidia's customers and investments, turn to other chips such as AWS's Trainium and Cerebras [2]. The local Bolt models also push the idea of private agents on personal machines, though TechCrunch notes that privacy-wary consumers may hesitate to give agents access to family, health and financial information [2].

Amazon backs a 960 MW, 12-reactor nuclear plant in Indiana

Amazon.com Inc. (NASDAQ: AMZN) announced on Monday that it will fund development of a proposed 960-megawatt nuclear plant in Indiana and be the first customer for its power, with American Electric Power operating the plant and X-energy supplying 12 Xe-100 small modular reactors [3]. The site is a demolished coal plant just south of Terre Haute [3]. It is the second commercial agreement between Amazon and X-energy and three times the size of the first, announced two years ago, and the companies say they ultimately plan 5 gigawatts of new US nuclear capacity by 2039 [3]. Unlike many newly announced power plants, these reactors would connect to the public grid, although Amazon says the power would also serve its data centres [3].

The timeline depends on X-energy delivering its first plant at a Dow Chemical site at Seadrift, Texas, where it has yet to break ground and where the state of Texas has sued the chemical plant over alleged non-compliance with water and solid-waste rules [3]. X-energy debuted on Nasdaq in April at $23 a share, rose 27 percent on its first day and has since fallen by nearly two-thirds [3]. TechCrunch adds that experts say mass manufacturing of small reactors often takes about a decade to produce benefits [3].

Jio's record IPO opens tomorrow with up to ₹30,213 crore on offer

Jio Platforms opens its IPO for subscription on October 21 and closes it on October 23, with shares expected to list on October 28 [5][6]. The issue is a fresh sale of up to 27 crore (270 million) shares with a face value of ₹10, priced at ₹1,065 to ₹1,119, which makes up to ₹30,213 crore at the top of the band [4][5]. Bids start at 12 shares and rise in multiples of 12, which is ₹13,428 at the top of the band by my arithmetic [5]. Shares worth up to ₹500 crore are reserved for eligible employees and up to ₹2,500 crore for eligible Reliance Industries shareholders [5]. None of the existing investors is selling, and Reliance Industries holds 66.43 percent [5]. Anchor bidding was scheduled for October 19, and I did not find a published anchor figure.

Reuters reports that the top of the band values Jio at about $108.3 billion, which would make it India's fourth-biggest company by market capitalisation behind Reliance Industries, Bharti Airtel and HDFC Bank [6]. Jio plans to use up to ₹275 billion ($2.89 billion) of the proceeds to repay borrowings at its telecom unit, run by Mukesh Ambani's son Akash [6]. The offer follows the National Stock Exchange listing in September that raised $2.3 billion, and in 2020 Jio raised more than $20.5 billion from 13 global investors for a stake of about 33 percent [6]. Figures differ by source: before the official band, PTI-based reports expected ₹37,700 crore ($3.8 billion) at ₹1,150 to ₹1,220 a share, while the filing-based numbers give up to ₹30,213 crore, so the lower figure is the one to use [5][7].

What to Watch Next

Four things to follow. First, Jio's subscription from October 21 to October 23, with listing expected on October 28 [5]. Second, the anchor allotment figure from October 19, which was not published in the sources I could read [4]. Third, whether X-energy delivers its first Seadrift plant, since the Amazon timeline depends on it [3]. Fourth, whether enterprises adopt agent monitoring that sits outside the AI labs, as Microsoft and Nvidia's safety platform propose [1].
