Nokia added roughly €5.6 billion in market value in a single trading session this week, and the reason has nothing to do with phones. The Finnish company's shares jumped 9.64% to close at €11.20 in Helsinki on Thursday, according to TS2's market coverage, its sharpest single-day move in weeks, driven by a new defense AI partnership and fresh signs that its bet on AI-driven optical networking is converting into real, booked business.
The catalyst was twofold. Nokia disclosed a defense AI collaboration with NestAI, delivering three integrated capabilities built for NATO operational requirements: AI-enabled command-and-control running on deployable 5G networks, mission planning with assured connectivity, and earlier threat detection in environments where communication access is limited. Nokia Defense chairman Mikko Hautala framed the significance plainly in comments reported by Benzinga, noting that AI only works in the field when it has secure, resilient connectivity behind it. Separately, Nokia landed roughly €1 billion in AI and cloud-related optical network orders, giving investors concrete evidence that the AI infrastructure buildout is translating into actual revenue rather than speculative hype, as detailed in NewsCase's analysis of the announcement.
From Telecom Hardware to AI Infrastructure Play
What makes this rally notable is how thoroughly it's rewriting Nokia's investment story. First-quarter sales to AI and cloud customers jumped 49% and now make up 8% of total company sales, with the Optical Networks unit, which handles fiber data transmission, growing 20%. Nokia raised its 2026 growth target for Network Infrastructure to 12% to 14%, citing accelerating demand. This mirrors broader momentum captured in our AI industry statistics and generative AI market data, where infrastructure spending continues to outpace even bullish analyst forecasts.
JPMorgan responded by lifting its price target to $21 from $14, and CFRA more than doubled its own target, arguing Nokia now deserves to trade more like an optical networking peer than a legacy telecom equipment vendor. The comparison to Ericsson, Nokia's longtime Swedish rival, is instructive. Ericsson shares also climbed nearly 7% on the same news cycle, and the two companies' fortunes remain closely linked heading into earnings season. Ericsson reports second-quarter results on July 14, with Nokia following on July 23.
Why the AI Halo Comes With Real Risk
Not everyone is convinced the rally reflects fundamentals catching up to price. Nokia now trades at roughly 79 times earnings, a multiple one analyst described as the stock "basking in the glow of the AI halo." That's a meaningful risk if AI infrastructure spending slows, component delays push out order timelines, or margins fail to expand as quickly as the market currently expects.
This mirrors a broader pattern across the AI infrastructure sector, similar to what's happened with Nvidia's server supply chain and other hardware players benefiting from hyperscaler capital expenditure documented in our Nvidia AI statistics coverage. The gap between narrative and confirmed earnings is exactly where volatility lives.
Why This Matters for Business
I've advised companies on AI strategy for four years, and Nokia's transformation is a useful case study in how traditional infrastructure companies can reposition around AI demand without necessarily building a foundation model themselves. For businesses evaluating vendors in networking or defense technology, this pivot is worth understanding alongside our broader look at what AI automation means for legacy infrastructure providers repositioning around AI demand.
What to Watch
The two upcoming earnings reports from Ericsson and Nokia will be the real test of whether defense AI partnerships and optical order growth are producing sustainable profit gains. Business leaders in adjacent infrastructure sectors should watch closely, since Nokia's pivot offers a template other established hardware companies may try to replicate.
