The rise in major initial public offerings in 2026 has raised a clear question: are equity markets close to a peak?
SpaceX has gone public, while AI companies including OpenAI and Anthropic are preparing for possible listings. Large IPOs often appear when confidence is high, valuations are supportive and companies believe public markets will provide the capital they need.
Companies may try to list before conditions weaken, while strong demand for new shares can suggest that optimism is becoming excessive. However, IPO activity does not reliably predict a market downturn.
IPOs usually confirm conditions that are already in place. Companies list when economic growth is firm, capital is available and demand for equities is strong. The current pipeline therefore reflects a supportive market backdrop rather than providing clear evidence that markets are about to fall.
The amount of new equity entering the market also appears manageable. Even very large companies often sell only a small percentage of their shares when they first list.
SpaceX was valued at $2.1 trillion, but only a limited portion of the company was made available for public trading. As a result, its weighting in the Nasdaq 100 remains relatively modest. Index funds will need to buy the shares during the next rebalance, but this is a normal process and is unlikely to cause major disruption across portfolios.
New IPO supply is also being offset by share buybacks. Corporate repurchases are expected to reach $1.9 trillion in 2026, while Nvidia has announced an $80 billion buyback. These programmes remove shares from the market, helping to balance the additional supply created by new listings.
Demand is another important factor. Many of the companies preparing to list operate within the AI sector, where interest remains strong. This means the new shares are entering an area that already attracts substantial capital.
The listings may also address a gap in the public market. Until now, direct access to foundational AI model developers has been limited. Potential IPOs from OpenAI and Anthropic would give shareholders a more direct route into the commercial development of advanced AI.
These companies also need large amounts of capital. Building AI models requires investment in computing power, data centres and global infrastructure. Public markets offer the scale of funding needed to support that expansion.
SpaceX’s listing establishes a public valuation benchmark for the space and aerospace industry, which has remained largely private. The company also has links to AI infrastructure and ambitions that may include space-based data centres.
