Is the honeymoon period for the AI investment bubble ready to meet reality? Researchers from a prominent bank think so.
Based on their research, two analysts have declared that the era of unchecked optimism around AI is ending, predicting 2026 will mark the technology’s most challenging year yet amid colliding realities.
In a report released 20 January 2026 named “The honeymoon is over for AI”, researchers Adrian Cox and Stefan Abrudan from Deutsche Bank have outlined three interlocking pressures: disillusionment in enterprise applications; supply chain dislocations; and surging public distrust.
According to their analysis, enterprises moving AI pilots to production are confronting stark limitations, including accuracy shortfalls in unpredictable settings, and costs that often exceed human labor equivalents.
Another finding was that, while innovators in Silicon Valley see revolutionary potential, most executives view gains as incremental — akin to a better saddle rather than a full vehicle upgrade. Also, the International Monetary Fund has cautioned that dashed productivity hopes could spark a broad market correction beyond AI firms.
Reports suggest that infrastructure strains are intensifying as AI demand outstrips capacity in chips, energy grids, talent, and water supplies. Hyperscalers have been sustaining massive investments via cash flows, but independent model developers face existential tests. This year, as AI pilot programs transition to full production, corporate users may wake up to the discovery of the gap between AI’s promise and its real-world utility.
The researchers note that distrust is poised to erupt into political and social uproar, fueled by lawsuits over copyrights and privacy, backlash against data center expansions, job loss fears, and US-China rivalry.
“Anxiety surrounding AI will escalate from a low murmur to a loud outcry,” the report warns, as regulators and the public demand accountability.
Markets have reacted swiftly: Nvidia shares dropped nearly 4%, Broadcom almost 5%, and the S&P 500 tech sector over 2% on Tuesday (US time). Yet the bank analysts have affirmed AI’s survival as a growth engine, urging investors to navigate the turbulence through diversified strategies.
