Does the 2026 IPO boom suggest markets are near a peak?

Many clients have asked us whether recent and planned mega initial public offerings (IPOs) are a sign that the market might be close to a top.

We explain what that means and look at what historic data indicates.

Is IPO activity a signal that markets are overheating?

Investors think in cycles, essentially repeating periods of economic growth, slowdowns, and recoveries.

If someone is calling the top or peak of the market, they are suggesting that assets like stocks might be overvalued and we could be about to see sell-offs. In the slowdown after a peak, you can also expect to see wider economic impacts such as rising unemployment and reduced consumer spending.

When IPOs pick up, investors often assume we are late in the cycle when optimism is high and companies rush to list before conditions turn. There is some historical evidence for this, but it can be misleading.

IPOs tend to reflect strength that is already in place rather than being an indicator that predicts what comes next. Companies go public when demand is strong, valuations are supportive, and capital is available – conditions typically associated with a solid economic backdrop.

Today is no exception: economic growth remains robust, reinforcing investor confidence and supporting risk appetite. Even without the current pipeline, today’s macroeconomic backdrop would likely have supported a pick-up in IPO activity.

Is equity supply becoming a problem for investors?

IPOs move equity from private to public markets, and large deals can temporarily absorb capital. But the scale of today’s market matters.

Even highly valued companies do not always have an immediate market impact, particularly given the scale of today’s equity markets and the limited shares available for trading.

Despite its $2.1 trillion valuation, SpaceX only listed a small portion of its shares, resulting in a relatively modest weighting in the Nasdaq 100. While index funds will need to buy shares as part of the upcoming rebalance, this is a routine process rather than a market-moving event. In short, it’s a landmark listing, but one that is unlikely to materially impact portfolios.

At the same time, companies are buying back their own shares at a record pace with JP Morgan estimating corporate buybacks will be $1.9 trillion in 2026. Nvidia’s recent $80 billion buyback is a striking example of equity supply being reduced, at a magnitude similar to the issuance coming from the SpaceX IPO.

Crucially, this is not supply coming into a soft market, it is arriving in one of the strongest areas of demand. Artificial intelligence (AI) continues to be a top priority for investors, many of whom are still looking to build exposure. As a result, new IPOs are effectively filling a gap rather than creating excess supply.

AI’s role in this cycle

AI sits at the centre of the current IPO wave and is a key reason why this cycle feels different. Many companies preparing to list are directly tied to the AI ecosystem.

These are not low-capex businesses. AI requires massive investment in compute, data centres, and global infrastructure. Public markets provide the depth of capital needed to support that expansion.

The listings of OpenAI and Anthropic could offer the first direct exposure to foundational AI models, giving investors a clear path to AI-driven growth and monetisation.

SpaceX introduces a different dynamic. Its listing sets a public benchmark for space and aerospace, an industry largely private until now. It also extends beyond aerospace, with growing exposure to AI and ambitions that could reach areas like space-based data centres.

What can we learn from past IPOs?

An important lesson is that share price performance on the first day of a public listing often matters far less than long-term fundamentals.

Some of the most successful companies, such as Amazon, Microsoft, and Nvidia, saw strong debuts, while others like Google and Meta had more mixed initial reactions. What mattered was not the first day, but the decades that followed.

Microsoft’s stock surged 69% on its first day of public trading compared to Meta, which lost 18% of its value in two days. However, both have proved to be strong long-term investments.

The common thread among long-term winners is clear: durable competitive advantages, large and expanding markets, and the ability to generate significant cash flow over time.

Confident markets

Ultimately, IPO booms do not necessarily mark the end of a cycle. In many cases, they signal that markets are confident and functional enough to fund the next phase of growth.

If anything, the more important driver has been the strength of the economic backdrop at the time of a listing. Robust growth tends to support both issuance and subsequent performance.

The recent pick-up in IPO activity is not a late-cycle warning; it reflects a strong macro backdrop, reopening capital markets, and a powerful structural tailwind from AI. Demand remains deep, supply is manageable, and investors are gaining access to a new generation of high-growth businesses.
