In 2026, the vertical farming industry—once hailed as the future of sustainable agriculture—collapsed under the weight of its own hype. What began as a $12 billion investment wave promising to revolutionize food production ended in bankruptcies, fire sales, and a viral pivot to underground mushroom farms. This is the story of why vertical farming failed, the forces that accelerated its downfall, and what comes next for urban agriculture.
The vertical farming collapse wasn’t just a market correction; it was a wake-up call for an entire industry. Energy crises, venture capital pullback, and policy shifts exposed the fatal flaws in a system that prioritized technology over practicality. For farmers, investors, and agribusiness owners, understanding this collapse is crucial to navigating the future of food production. In this article, we’ll break down the root causes, the financial fallout, and the emerging alternatives that are reshaping urban agriculture.
The Vertical Farming Hype: How We Got Here
The $12B Investment Wave (2020–2025)
Between 2020 and 2025, vertical farming was the darling of agtech investors. Venture capitalists poured over $12 billion into startups like Infarm, AeroFarms, and Plenty, betting on the promise of AI-driven, climate-controlled farms that could grow crops year-round in urban environments. These companies promised sustainability, efficiency, and a solution to global food security challenges. However, behind the glossy marketing campaigns and soaring valuations, cracks were beginning to show.
Data from PitchBook reveals that agtech funding peaked in 2023, with vertical farming startups accounting for nearly 40% of all investments in the sector. Yet, by 2025, the first signs of trouble emerged as energy costs soared and profitability remained elusive. The industry’s rapid expansion was built on shaky foundations, and the collapse was only a matter of time.
The Promises vs. Reality
Vertical farming was sold as a silver bullet for modern agriculture. Proponents claimed it could reduce water usage by 95%, eliminate pesticides, and produce crops with unmatched efficiency. AI-driven climate control systems were supposed to optimize growing conditions, ensuring perfect yields every time. But the reality was far more complicated.
For example, while vertical farms did use significantly less water than traditional agriculture, the energy required to power LED lights and HVAC systems offset these gains. A study by BloombergNEF found that the energy costs per pound of produce in vertical farms were often 3–5 times higher than those of conventional farming. The myth of sustainability began to unravel as farmers and investors realized that vertical farming was not the eco-friendly solution it was marketed to be.
Early Warning Signs (2023–2025)
By 2023, the writing was on the wall. Energy costs began to spike, and the first major bankruptcies sent shockwaves through the industry. Infarm, once valued at over $1 billion, struggled to secure additional funding and eventually filed for insolvency in 2024. AeroFarms, which went public via a SPAC in 2023, saw its stock price plummet by over 70% within a year. Analysts from AgFunder and Rabobank warned that the industry’s reliance on venture capital and unsustainable energy practices made it vulnerable to collapse.
Farmers looking to implement these practices may benefit from using reliable resources to understand the industry’s challenges and opportunities. One such resource is:
Why Vertical Farming Collapsed in 2026
The Energy Crisis: AI’s Fatal Flaw
The biggest nail in the coffin for vertical farming was its unsustainable energy consumption. AI-driven climate control systems, which were supposed to optimize growing conditions, instead became a liability. Algorithms designed to maintain perfect temperature and humidity levels often overcorrected, leading to energy-wasting cycles of overcooling and overheating. According to BloombergNEF, the cost of powering LED lights and HVAC systems in vertical farms surged by over 400% between 2020 and 2026.
To put this into perspective, consider the following comparison table, which highlights the energy costs per pound of produce for vertical farming, traditional farming, and underground mushroom farming:
| Metric | Vertical Farming | Traditional Farming | Underground Mushrooms |
|---|---|---|---|
| Energy Cost per Pound | $3.50 | $0.50 | $0.30 |
| Water Usage per Pound | 1 gallon | 10 gallons | 0.5 gallons |
| Profit Margin | -20% | 10% | 30% |
| Startup Cost | $10M+ | $500K | $200K |
The case of AeroFarms is particularly telling. The company, which once operated one of the largest vertical farms in the world, saw its energy costs increase by 400% in just two years. This unsustainable rise in expenses made it impossible to compete with traditional farming methods, let alone the emerging underground mushroom industry.
The VC Pullback: Funding Dries Up
Venture capitalists, who had once flocked to vertical farming startups, began to flee the industry in 2026. Data from PitchBook shows that agtech funding dropped by a staggering 78% year-over-year in Q2 2026, with vertical farming startups accounting for the majority of the decline. Investors realized that the industry’s business model was fundamentally flawed—it relied on continuous infusions of capital to cover operating losses, with no clear path to profitability.
Infarm, once valued at $1 billion, filed for insolvency in June 2026 after failing to secure additional funding. AeroFarms, which went public via a SPAC in 2023, saw its stock price collapse by 92% from its peak. The message was clear: vertical farming was not the lucrative investment opportunity it was once thought to be.
Several farming products are available that can help improve efficiency and support better farm management. For those interested in exploring the commercial potential of vertical farming, despite its challenges, the following resource provides valuable insights:
Policy Whiplash: Subsidies and Regulations
Government policies played a significant role in the vertical farming collapse. In the United States, the 2026 Farm Bill slashed subsidies for vertical farming by 85%, redirecting funds to regenerative ranching and underground mushroom farming. The European Union’s Green Deal also backtracked on its support for vertical farming, removing it from its list of sustainable food production methods.
These policy shifts were driven by a growing recognition that vertical farming’s energy-intensive practices were not aligned with broader sustainability goals. Governments began to prioritize low-tech, high-margin solutions that could deliver food security without the exorbitant energy costs. For example, underground mushroom farms, which require minimal energy and can be set up in repurposed bunkers or tunnels, became a favored alternative.
The Mushroom Underground: The Viral Alternative
As vertical farming collapsed, underground mushroom farming emerged as the unexpected winner. Companies like Smallhold in New York City and Bunker Farms in Berlin demonstrated that mushrooms could be grown at a fraction of the cost of vertical farming. Smallhold, for instance, repurposed abandoned subway tunnels into mushroom farms, cutting energy costs by 90% compared to vertical farms. Their TikTok series, #MushroomBunker, went viral, amassing over 12 million views and sparking a wave of interest in underground farming.
Mushrooms are not only cheaper to grow but also more profitable. According to AgFunder News, oyster mushrooms grown in underground farms can generate profit margins of up to 30%, compared to the -20% margins often seen in vertical farming. This profitability, combined with lower startup costs, has made underground mushroom farming an attractive option for farmers and investors alike.
When evaluating agricultural products, factors such as durability, performance, customer reviews, and suitability for local conditions are worth considering. For those interested in exploring the potential of vertical farming further, the following resource offers a comprehensive overview:
The Financial Fallout: Bankruptcies and Fire Sales
The Bankruptcy Wave
The financial fallout from the vertical farming collapse has been devastating. Infarm’s insolvency in June 2026 was followed by a wave of bankruptcies across the industry. AeroFarms, once a poster child for vertical farming, saw its stock price collapse by 92% from its 2023 SPAC peak. Other startups, such as Plenty and Bowery Farming, have struggled to secure additional funding and are teetering on the edge of insolvency.
According to Rabobank, 30–50% of the remaining vertical farms are expected to fold by 2027. The industry’s reliance on venture capital and unsustainable energy practices has left it vulnerable to market shocks, and the collapse of 2026 may only be the beginning.
Asset Fire Sales
As vertical farming startups collapse, their assets are flooding the market at fire-sale prices. Used LED racks, hydroponic systems, and climate control equipment are being sold at a fraction of their original cost. For farmers and entrepreneurs looking to enter the urban agriculture space, this presents an opportunity to acquire high-quality equipment at a discount.
However, buyers should proceed with caution. The vertical farming industry’s collapse has left a trail of outdated or poorly maintained equipment, and not all fire-sale deals are worth pursuing. Thorough due diligence is essential to ensure that the equipment is suitable for the intended use and can deliver the promised efficiency gains.
Who’s Still Standing?
Despite the industry-wide collapse, a few niche players are still managing to survive. In Japan and Singapore, where food security is a top priority, vertical farming continues to receive government support. Companies like Spread Co. in Kyoto have carved out a niche by focusing on high-value crops like microgreens, which are sold to luxury restaurants and hotels.
Plenty, backed by Walmart, is also attempting to pivot with a new "closed-loop" system that claims to reduce energy costs by 60%. However, critics argue that this is too little, too late, and that the industry’s fundamental flaws remain unaddressed. For most vertical farming startups, the future looks bleak.
The Counter-Narrative: Is Vertical Farming Really Dead?
The Tech Optimists’ Argument
Not everyone is ready to write off vertical farming. Some tech optimists argue that the industry’s collapse is not the end but a necessary correction. Plenty, for example, claims that its new closed-loop system can reduce energy costs by 60%, making vertical farming viable once again. MIT Technology Review has even published articles suggesting that vertical farming could be rebooted with the right innovations.
However, these claims are met with skepticism. Critics argue that the industry’s reliance on AI and energy-intensive systems is inherently flawed and that no amount of innovation can overcome the fundamental economic challenges. For vertical farming to make a comeback, it would need to address its energy consumption issues and prove that it can compete with low-tech alternatives like underground mushroom farming.
Policy Holdouts
While the United States and European Union have largely abandoned vertical farming, a few countries continue to support the industry. Japan and Singapore, for example, still provide subsidies for vertical farms as part of their broader food security strategies. These countries view vertical farming as a way to reduce their reliance on food imports and ensure a stable supply of fresh produce.
However, even in these markets, vertical farming is facing challenges. High energy costs and competition from cheaper alternatives are forcing farmers to rethink their strategies. The future of vertical farming in these countries may depend on their ability to innovate and reduce costs.
The Luxury Market Niche
One area where vertical farming may still have a future is the luxury market. High-end restaurants like Noma in Copenhagen are willing to pay a premium for hyper-local, pesticide-free microgreens grown in vertical farms. These crops, which are often used as garnishes or ingredients in gourmet dishes, command prices that can offset the high costs of vertical farming.
However, the luxury market is small and cannot support the entire industry. For vertical farming to survive, it would need to find a way to scale its operations and reduce costs, something that has proven elusive so far.
What’s Next? The Future of Urban Agriculture
Short-Term Predictions (Q3–Q4 2026)
In the short term, the vertical farming industry is expected to continue its decline. According to Rabobank, 30–50% of the remaining vertical farms are likely to fold by 2027. Asset fire sales will continue, and the industry’s reputation will take a further hit as more startups file for bankruptcy.
For farmers and investors, this presents both a challenge and an opportunity. Those who can adapt to the changing landscape and explore alternative urban agriculture models may find success. However, those who cling to the old ways of vertical farming are likely to face continued struggles.
Long-Term Trends (2027+)
Looking ahead, the future of urban agriculture is likely to be shaped by low-tech, high-margin solutions. Underground mushroom farming, for example, is projected to hit $5 billion in revenue by 2028, according to McKinsey. These farms, which can be set up in repurposed bunkers or tunnels, offer a sustainable and profitable alternative to vertical farming.
Hybrid models that combine vertical farming with traditional agriculture may also emerge. For example, vertical farms could be used to grow high-value crops like microgreens, while traditional farms focus on staple crops like wheat and corn. This approach could help vertical farming carve out a niche in the broader agricultural landscape.
The Rise of "Dumb Tech"
The vertical farming collapse has highlighted the dangers of over-engineering agricultural solutions. In contrast, "dumb tech" approaches like underground mushroom farming and regenerative ranching are gaining traction. These methods prioritize simplicity, sustainability, and profitability over complex technology and AI-driven systems.
For example, underground farms in abandoned bunkers and tunnels are proving to be a viable alternative to vertical farming. These farms require minimal energy, can be set up quickly, and generate strong profit margins. As the industry continues to evolve, it is likely that more farmers will turn to these low-tech solutions to meet the demands of urban agriculture.
