Good evening,
Hope your week’s treating you well so far. Today’s newsletter is all about one thing: Anthropic just showed us what happens when AI stops being “a feature” and starts eating entire industries.
✨TODAY’s HIGHLIGHTS
Anthropic’s Industry Blitz: Anthropic rolls out Claude Cowork legal plugins, Claude Code Security, and COBOL modernization – and entire categories of legacy software suddenly look fragile.
$1 Trillion SaaSpocalypse: Software incumbents from Salesforce to IBM shed hundreds of billions in value as Wall Street prices in AI agents replacing per-seat SaaS.
AI vs. “Per-Seat” Pricing: The classic “more employees = more licenses” model is breaking as AI agents handle work without needing seats, pushing the shift to outcome-based pricing.
Security Gets an AI Upgrade: Claude Code Security enters research preview, giving defenders frontier-level vulnerability detection that used to require elite security teams.
The Lithium Boom is Heating Up
Thanks to growing demand, lithium stock prices grew 2X+ from June 2025 to January 2026. $ALB climbed as high as 227%. $LAC hit 151%. $SQM, 159%.
This $1B unicorn’s patented technology can recover 3X more lithium than traditional methods. That’s earned investment from leaders like General Motors.
Now they’re preparing for commercial production just as experts project 5X demand growth by 2040. They’ve announced what could be one of the US’ largest lithium production facilities and have rights to approximately 150,000 lithium-rich acres across North and South America.
Unlike public stocks, you can buy private EnergyX shares alongside 40,000+ other investors. Invest for $11/share by the 2/26 deadline.
This is a paid advertisement for EnergyX Regulation A offering. Please read the offering circular at invest.energyx.com. Under Regulation A, a company may change its share price by up to 20% without requalifying the offering with the Securities and Exchange Commission.
🛠️ TOOL OF THE DAY
This week’s spotlight isn’t a cute little productivity app. It’s Anthropic Claude Cowork and Claude Code, the duo behind the “Anthropic just destroyed an industry” headline.
What it is
Claude Cowork is an agentic work environment that lets Claude plan, execute, and iterate through multi-step workflows – not just answer prompts. Legal, finance, sales, and support teams get domain-specific “plugins” that feel more like AI teammates than chatbots.
Claude Code is the developer-facing side: an AI coding agent that lives in your terminal and now branches into security scanning and legacy modernization (yes, including COBOL).
Who it’s for
Developers who want AI to actually ship code, not just autocomplete.
Legal, compliance, and ops teams drowning in documents and workflows.
Small businesses that can’t afford big consulting projects but still need automation.
If you’ve ever wished your “AI tool” could run a full process end-to-end instead of giving you snippets, this is built for you.
Highlights
Legal plugins for Cowork: Automate contract review, NDA triage, compliance checks, vendor risk, and templated responses with playbook-based reviews tailored to your org.
Industry-shaking impact: Launch of the legal plugin coincided with sharp drops in legal software and data providers as investors realized the platform layer is now a direct competitor.
Claude Code Security: New capability that scans codebases for subtle, high-severity vulnerabilities and proposes patches for human review, in limited research preview for enterprise, teams, and open-source maintainers.
COBOL modernization: Claude Code can help explore, analyze, and modernize COBOL systems that used to need huge consulting teams and multi-year projects..
Play with it on a non-production project first so you can map how these agents actually behave in your environment.
📊 AI INDUSTRY INSIGHTS
Anthropic’s Claude Cowork legal plugin triggered a massive selloff across legal and data-software firms, wiping roughly hundreds of billions in market cap as stocks like Thomson Reuters, RELX, and London Stock Exchange Group fell sharply. Markets aren’t just reacting to “another AI feature” – they’re pricing in the idea that core legal workflows may move into AI-first environments rather than traditional SaaS tools.
Why it matters: If you build vertical SaaS or sell knowledge work as a service, this is your warning shot – AI platforms can suddenly become your direct competitor and distribution channel in one move.
Anthropic launched Claude Code Security, a new capability that scans entire codebases for subtle, high-severity vulnerabilities and proposes targeted patches for human review, in a limited research preview. It’s aimed at giving defenders frontier-level capabilities before attackers fully weaponize similar models, with expedited access for open-source maintainers.
Why it matters: For small teams and open-source projects without full security staff, this shrinks the gap between “we hope it’s safe” and “we can continuously harden our code” using AI as a force multiplier.
Claude Code’s ability to analyze and modernize massive COBOL codebases – documenting workflows, mapping dependencies, and surfacing risks – spooked investors, contributing to IBM’s steepest one-day share drop in decades and broader concern around legacy software vendors. Anthropic argues AI flips the economics of legacy modernization: understanding old systems is no longer more expensive than rewriting them.
Why it matters: If your business depends on maintaining or integrating with legacy platforms, AI-powered modernization is about to compress multi-year projects into months – threatening some service lines but opening huge opportunities for those who adopt it early.
