Recognising Hype Cycles in Emerging Sectors and Private Markets
In recent years, investors in Australia and globally have increasingly expressed concern that they are missing out on what might be the next big boom: artificial intelligence, climate tech, biotech, digital infrastructure and a wave of private equity deals. While many of these emerging sectors do present genuine opportunities, there is also a risk of being swept up in hype cycles, where high expectations and exuberant valuations precede disillusionment or correction. For any prudent investor or business, recognising those cycles – and resisting FOMO – can be the difference between participation in a durable trend and suffering losses or overpaying for risk.
Understanding Hype Cycles
A hype cycle refers to a pattern in the public, investor, or media perception of a new technology or sector. Gartner popularised a framework that traces an arc from an early innovation trigger, through inflated expectations, into a trough of disillusionment and then onto more realistic foundations. That same pattern can occur across any sector.
What makes private markets especially vulnerable is that valuations are less transparent, time horizons are longer, liquidity is limited and many companies are early stage pre-revenue. The promise can appear much greater because failure is often less visible until it is large and too late. That amplifies FOMO: it is easier to hear about the success stories than the many things that did not work out.
How FOMO Manifests in Emerging Sectors and Private Markets
In Australia, surveys show that roughly one third of investors say they feel FOMO regarding private asset opportunities, citing companies like SpaceX or OpenAI as examples of what they think they may be missing.
Many investors do not fully appreciate the structural differences between public and private markets including valuation timing, liquidity, risk of failure and regulatory exposure.
Examples of sectors currently subject to hype include:
AI and Data Infrastructure: Firms in AI-related infrastructure have seen soaring investor interest. One tech firm, for example, formerly focused on bitcoin mining, pivoted towards AI infrastructure and saw its value rise dramatically—riding what appears to be the AI/data centre boom. Others have failed to live up to the hype and seen their valuation decline significantly.
Environmental Transition / Clean Energy: There is a proliferation of funds and projects in clean energy, decarbonisation, electric vehicle supply, carbon credits. One private equity fund raised around A$350 million to invest in a variety of net-zero and sustainability themes.
Recognising the Warning Signs
To avoid being caught in an overheated stage of a hype cycle, there are several red flags and diagnostics to pay attention to:
Valuations rising faster than revenues or realistic business economics. When investor enthusiasm pushes up valuations because of projected growth rather than current earnings, the risk is that projections are too optimistic. Businesses may be growing, but perhaps not fast enough to justify the prices being paid in private funding rounds or secondary markets.
A gap between public narrative and private traction. If much of the buzz is coming from media, policy announcements, or analyst reports, but few companies are demonstrating sustainable profitability or scalable business models, the sector may be in the phase of inflated expectations.
Heavy concentration of hype among certain kinds of investors or deal structures. Retail or less experienced investors may be more susceptible; closed-end funds with long lock-ups and occasional, non-transparent disclosures may hide risk. If many investors are chasing deals simply because others are doing so, without independent diligence, this is dangerous.
Regulatory, technological or supply-chain risk that is underplayed. Emerging sectors often suffer from regulatory uncertainties, shifting policy incentives, or technological bottlenecks. For example, clean energy or carbon markets may depend heavily on government subsidies, policy continuity, or infrastructure (like grid access) that is not yet mature.
Liquidity risk and valuation lag. In private markets, valuations are often infrequent. What looks like strong performance may actually be last-quarter truths, not reflective of current stress. Also, when there is a downturn, exit opportunities (IPO, M&A) may be limited, reducing ability for investors to realise gains or cut losses.
Signs of fatigue or cooling in follow-on capital. If the newest funding rounds demand much higher performance to raise money, or fewer new entrants or funds are launching in the sector, that can indicate the crest of the hype curve is being reached.
Strategic Responses: How to Resist FOMO
Recognising hype is only the first step. The more difficult part is resisting the pull of FOMO, especially when peers, media, or clients seem to be jumping in. The following strategic responses help preserve capital and position for long-term gains.
Always begin with alignment of risk appetite, investment horizon and portfolio diversification. Investors need to define what they are willing to lose, what outcomes they seek and over what timeframe. Without that clarity, FOMO can lead to overexposure to speculative bets.
Undertake rigorous due diligence, especially in emerging sectors. This includes deep investigation of business models, unit economics, path to profitability, what regulatory risks exist, what the competitive landscape is and what supply-chain and scaling challenges exist. Speak with multiple stakeholders: customers, suppliers, regulators.
Focus on proven operators or funds that have track records across cycles. In private markets, managers who have navigated downturns before and who have transparent disclosures are more valuable than managers who simply have bold visions. Sector specialists can offer deeper insight, but only if they are capable of adjusting course when market conditions shift.
Monitor leading indicators of bubble risk. Look for metrics like margin compression, lower incremental returns on new investments in the sector, declining valuations in public comparables, weakening demand even as supply (or investment inflows) continues to increase.
Be cautious of “all-in” behavior. Sometimes opportunity is real; other times, temptation arises to put more capital in emerging sectors than prudence should allow. Ensuring that exposure to any one sector or theme remains bounded helps absorb potential corrections without catastrophic loss.
Think about liquidity and exit. In private markets especially, you must understand when and how you will exit. Whether through sale, IPO, secondary market or other means—if exit paths are thin or crowded, what looks like a promising niche may instead be a trap of locked up capital.
Examples of “Hype vs. Reality”
Australia has recent experience of both sides of the spectrum. An example illustrates the gap between promise and actual outcomes, showing how hype can mislead but also where opportunity has won through.
One example in the ASX market is DigiCo, a data centres-focused REIT floated with high expectations. The IPO was promoted on the narrative of data growth, AI, and need for infrastructure. Since listing the share price has fallen significantly reflecting concerns about the quality of assets growth prospects profitability. It offers a cautionary tale of how the hype among institutional and retail investors doesn’t always match underlying fundamentals.
There is also evidence that many Australian businesses remain “stuck” in the AI or design-and-make hype cycle. According to reporting, many firms have adopted AI rhetoric and invested in pilot projects, but find converting those into scalable, profitable operations harder than expected. High costs, labour shortages, uncertain return on heavy investment and the regulatory burden have cut into margins. Thus, while AI remains a driver of innovation, many organisations are now adjusting expectations downward from the initial hype.
The Benefits of Awareness: Why It Pays to Recognise and Wait
Recognising that a sector may be in the inflated expectations part of a cycle provides strategic advantages. First, one can get in earlier before the hype peaks—or wait until disillusionment and then buy in when valuations are more reasonable. Second, avoiding overpaying for risk helps preserve capital, which is essential in private markets where losses are magnified by leverage, illiquidity, or slow growth. Third, a disciplined stance can lead to stronger long-term performance: companies or funds with resilient business models often survive cycles, adapt and capture growth when hype subsides. Finally, credibility matters: for institutional investors, advisers, or businesses themselves, preserving trust and avoiding reputational loss is important.
Emerging sectors and private markets will continue to draw investor attention and excitement. Many of the most powerful innovation and value-creation stories of the next decade are likely to come from areas that are currently hyped. But the pull of FOMO carries real risk. Inflated expectations, opaque valuations, regulatory and scaling risk and liquidity constraints compound to make early investor enthusiasm a double-edged sword.
Investors and businesses benefit by being especially methodical: setting clear goals, demanding evidentiary rigor from claims, attending to exit paths and resisting narratives that sound compelling but are thin on detail. The sectors of AI, energy transition, ag-tech, digital infrastructure, among others, will likely produce winners but recognising which companies or funds are built for longevity rather than just riding the wave of hype is essential. In short, avoiding FOMO means not only watching the horizon but also keeping both eyes on what lies underfoot.
