From mainframe dinosaurs to AI-native infrastructure—February 24, 2026 marks the moment AI stopped augmenting and started replacing.
The $30 Billion Message
At 9:30 AM Eastern Time on February 24, 2026, IBM shareholders watched in disbelief as the stock began a cascade that would end with a 13.15% single-day decline—the company’s worst performance in decades . The trigger? Not a missed earnings report, not a regulatory investigation, but a simple blog post from Anthropic announcing that Claude Code can now automate COBOL modernization .
By day’s end, IBM had lost over $30 billion in market value. The message was unmistakable: No system is too legacy, no code too ancient, to escape AI’s reach.
The COBOL Trap: Why This Matters
COBOL (Common Business-Oriented Language) turns 67 this year. Yet this aging programming language still processes 95% of all U.S. ATM transactions and runs critical systems in finance, aviation, and government agencies worldwide . Trillions of lines of COBOL code remain in production, supported by a rapidly shrinking workforce of aging developers.
For decades, IBM has built a lucrative business around this reality—providing mainframe systems, maintenance services, and modernization consulting. The company’s recent focus on “hybrid cloud and AI” couldn’t shield it from an AI that directly attacks its most defensible legacy moat.
Anthropic’s announcement was precise: Claude Code can now handle the “exploration and analysis phases” of COBOL modernization—work that previously required massive consulting teams and months of effort . The implication is terrifying for legacy vendors: if AI can understand and transform COBOL, it can do the same for any aging codebase.
The Broader AI Infrastructure Boom
While IBM’s collapse dominated headlines, other AI infrastructure stories signaled where capital is flowing instead:
Amazon’s $12 Billion Bet on Louisiana
Amazon announced a $12 billion investment in Louisiana to build a new AI data center campus, creating over 2,200 direct and indirect jobs . The facility will support AWS’s AI and cloud computing infrastructure, part of Amazon’s planned $200 billion capital expenditure for 2026 . This isn’t speculative spending—it’s the physical foundation of the AI economy.
OpenAI’s Strategic Pivot
OpenAI announced it is adjusting its “Stargate” project strategy, temporarily shelving self-built infrastructure in favor of deeper collaboration with Oracle and SoftBank . This pragmatic shift recognizes that speed matters more than control in the AI infrastructure race. Simultaneously, OpenAI forged multi-year partnerships with four consulting giants—Accenture, BCG, Capgemini, and McKinsey—to deploy its Frontier enterprise AI agent platform . The message: AI agents are entering the enterprise at scale, and they need consulting muscle to land.
Hardware and Chips: The Enablers
ASML, the Dutch lithography giant, revealed an EUV light source breakthrough that promises to increase chip production by 50% by 2030 . This matters because every AI data center, every model training run, every autonomous system depends on the continued scaling of semiconductor manufacturing.
SK Hynix chairman Chey Tae-won committed to expanding HBM (High Bandwidth Memory) production, explicitly citing AI-driven market uncertainty as both challenge and opportunity .
Governance and Geopolitics
The Canadian government announced that “all options are on the table” in responding to OpenAI, with the AI minister scheduled to meet OpenAI’s safety team today . This reflects growing global unease about concentrated AI power.
Meanwhile, European Central Bank President Christine Lagarde offered a contrarian perspective: even if Europe isn’t leading in frontier AI models, it can still benefit enormously by applying AI to its industrial strengths—particularly manufacturing and robotics, where European firms already lead in adoption .
The Workforce Time Bomb
Former Citigroup innovation executive Rob Garrick issued a stark warning: AI robots will outnumber human workers within decades . His reasoning is brutally simple: corporate management is optimized for profitability, and AI offers a path to radically lower labor costs. “Human employees will be left far behind,” Garrick told CNBC .
This isn’t distant speculation. Toyota has already contracted Agility Robotics’ humanoid robots for its Canadian factory . Samsung integrated Perplexity AI into Galaxy devices, enabling voice-activated AI that can access and control phone functions . Uber formed a dedicated autonomous vehicles division, aiming to make self-driving commercially viable . The physical AI revolution is accelerating.
The Strategic Implications for Leaders
- No legacy system is safe. If COBOL—the most entrenched enterprise language—can be disrupted by AI, every proprietary system should be considered at risk. Leaders must ask: “What would happen if AI could replace our core systems tomorrow?”
- Infrastructure is the new competitive advantage. With Amazon spending $200 billion this year alone, the gap between AI haves and have-nots will widen rapidly. Organizations must secure access to compute, data, and talent.
- Partnerships beat building. OpenAI’s pivot from self-built infrastructure to Oracle/SoftBank collaboration acknowledges a truth for most organizations: focus on application, not foundation.
- Governance is catching up. From Canadian regulatory warnings to European industrial strategy, governments are moving from observation to intervention. Compliance will become a constraint—and an opportunity.
The COBOL Moment
February 24, 2026 will be remembered as the day AI proved it could eat not just software, but the infrastructure beneath software. IBM’s $30 billion loss is a down payment on a larger truth: in the AI-native era, no code is too old, no system too sacred, no business model too entrenched.
The only question for leaders is whether they’ll be the ones writing the AI code—or watching their stock price when someone else does.
