The AI bubble is showing signs of bursting. Defensive strategies for SMEs/mid-market companies: diversification, realistic ROI and anti-fragile positioning.


In May 2025, a Reddit post titled "My god there is an enormous crash just waiting to happen" garnered over 1,570 upvotes and nearly 600 comments. The message was clear: AI company valuations are disconnected from their actual revenue, investments exceed all economic rationality, and a brutal correction seems inevitable.
This isn't an isolated alarm bell. Goldman Sachs analysts estimate that AI infrastructure investments will reach $1 trillion in the coming years, with returns on investment still uncertain. Sequoia Capital has calculated an "AI revenue gap" of $500 billion between infrastructure spending and revenue generated by AI applications.
For SME and mid-market company leaders in France and Belgium, the question is no longer whether a correction will occur, but how to prepare for it. This article breaks down the signs of the AI bubble and offers concrete strategies to transform this risk into a competitive advantage.
Nvidia, symbol of the AI gold rush, saw its market capitalization exceed $3 trillion in 2024. The price-to-earnings ratio of many AI companies ranges between 50 and 200, compared to a historical average of 15 to 20 for the S&P 500. This disconnect echoes the Internet bubble of 2000, where "eyeballs" replaced revenue as a valuation metric.
Hyperscalers (Microsoft, Google, Amazon, Meta) are building data centers at a frantic pace. Meta announced a $65 billion investment for 2025. The problem: actual demand for AI inference remains below installed capacity. When supply structurally exceeds demand, prices collapse and margins follow.
The B2B AI tools market currently includes over 15,000 startups. The majority will never achieve profitability. Acquisitions and closures will accelerate in 2025-2026. If your business depends on a niche AI tool, you risk seeing your supplier disappear or pivot abruptly.
According to a 2024 Gartner study, 30% of generative AI projects will be abandoned after the pilot phase by 2025. Marketing promises exceed the actual capabilities of tools. This growing disappointment fuels skepticism that can turn into rejection.
Large enterprises can absorb the failure of a €2 million AI project. For an SME with an annual technology budget of €200,000, a bad AI investment can compromise digital transformation for three years.
Three vulnerabilities specific to SMEs and mid-market companies:
At AISOS, we observe that 60% of SMEs consulting with us have invested in AI tools without defining clear success metrics. This absence of framework makes any objective evaluation of return on investment impossible.
The golden rule: never depend on a single supplier for a critical function. Here's how to apply this principle to your AI infrastructure.
List all AI tools used in your company, including "shadow AI" adopted by teams without IT validation. For each tool, identify:
For critical uses, test and maintain connections with at least two LLM providers. Concrete examples:
This redundancy has a cost, but it protects you against unilateral price increases, service outages, and changes in terms of use.
Before adopting an AI tool, verify that you can export your data in a standard format. Custom prompts, fine-tunings, and knowledge bases must remain your property and be transferable.
Enthusiasm for AI has generated unrealistic expectations. To avoid disappointments, adopt a rigorous evaluation methodology.
For each AI project, calculate a score based on four criteria:
RICE Score = (Reach × Impact × Confidence) / Effort
Ruthlessly prioritize projects with the best score. Abandon those based on unverified assumptions.
Too many companies deploy AI without a baseline. How can you know if you've gained 20% productivity if you haven't measured initial productivity?
Metrics to track mandatory:
With an AI project failure rate estimated at 70-80% (source: Gartner), your business case must integrate this probability. A project promising €100,000 in gains with a 30% chance of success has an expected value of only €30,000.
The concept of anti-fragility, developed by Nassim Taleb, describes systems that strengthen under stress. Here's how to apply it to your AI strategy.
Tools change, skills remain. Train your teams to:
An employee who understands AI can switch from ChatGPT to Claude in one day. An employee who has memorized specific prompts is lost if the interface changes.
During a correction period, companies that invested in AI as "human replacement" will suffer. Those who used it to enhance their distinctive capabilities will prosper.
What AI will not replace:
Invest in these areas alongside your AI projects.
Don't deploy 100% of your innovation budget in AI today. Keep 20 to 30% in reserve to:
An AI crash will have consequences on how businesses search for information. AI answer engines (ChatGPT, Perplexity, Gemini) might see their usage evolve, but they won't disappear.
A stock market correction doesn't erase established usage patterns. Google survived the bursting of the Internet bubble. LLMs will survive the bursting of the AI bubble, probably in consolidated form around three or four major players.
Companies that have built their thematic authority and presence in sources cited by LLMs will benefit from a lasting advantage. AISOS audits reveal that companies mentioned in AI responses today retain this position in 85% of cases six months later, even after major model updates.
The predicted AI crash is not a fatality to endure, but a scenario to integrate into your strategic planning. Companies that will emerge stronger are those that will have:
The Internet bubble destroyed thousands of overvalued companies, but it also enabled the emergence of Amazon, Google, and digital commerce fundamentals. The AI bubble will probably follow the same pattern: destruction of excesses, consolidation around viable players, and massive opportunities for prepared companies.
Your next step: audit your current AI dependency and build your resilience plan. Leaders who act now will have a decisive advantage when the correction arrives.
