The artificial intelligence boom is entering a new phase. After years in which investment in the sector was largely concentrated in venture capital and private markets, some of the industry’s most valuable companies are now exploring the possibility of accessing public capital. Among them, OpenAI occupies a uniquely prominent position, not only because of its technological influence but also because it has become the company most closely associated with the emergence of generative artificial intelligence as a mainstream economic phenomenon.

Reports that OpenAI has filed documentation with the Securities and Exchange Commission have intensified speculation about stock market quoting, that could happen within days. While insisting that no final decision has been made, the move for OpenAI nevertheless reflects a broader trend: the gradual transition of artificial intelligence from a venture-capital story to a public-market investment theme.

From technological breakthrough to financial asset

The interest concerning a potential OpenAI floatation is not difficult to explain. Since the launch of ChatGPT in late 2022, the company has become the public face of a technological transformation whose economic implications are still being debated. Generative AI has begun having a huge impact on sectors ranging from software development and professional services to healthcare and education. And precisely for this reason, it attracts a large amount of investment.

In this context, OpenAI’s value extends beyond its products or revenues. The company has become, in many respects, a proxy for investor confidence in the future of artificial intelligence itself. And for this, investors look at OpenAI as representative of the entire AI sector.

The capital-intensive reality of AI

Yet behind the excitement lies a more complex reality. Unlike many previous software revolutions, artificial intelligence is exceptionally capital-intensive. And while the growth currently looks positive, this capital is coming principally from figures within the same industry, creating what increasingly looks like a bubble.

The development of increasingly sophisticated models requires enormous investments in computing infrastructure, advanced semiconductors, energy consumption, and highly specialised research talent. The race towards ever more capable systems has effectively become an arms race in computational resources, creating substantial financing requirements even for the sector’s most successful companies.

For OpenAI, access to public markets could therefore provide advantages that extend beyond prestige or liquidity. A successful IPO would strengthen the company’s ability to fund future development while reducing dependence on a relatively small group of private investors and strategic partners.

At the same time, becoming a public company would introduce new constraints. Shareholders tend to prioritise predictable growth, profitability, and transparency, objectives that do not always align comfortably with the long-term and often experimental nature of frontier AI research. And it remains to be seen whether the industry can find confidence in investors from outside the bubble.

Competition is intensifying

Another factor likely to influence investor sentiment is the increasingly competitive nature of the AI landscape.

Two years ago, OpenAI appeared to enjoy a considerable first-mover advantage. Today, however, the competitive environment appears greatly different. Anthropic has emerged as a serious challenger in enterprise applications, while Google and Meta continue to deploy enormous financial and technical resources in pursuit of their own AI ambitions. Meanwhile, Chinese technology firms are rapidly narrowing the gap despite restrictions on access to advanced semiconductor technology.

The implication is clear: investors evaluating OpenAI will not simply be assessing the prospects of a single company but the sustainability of its competitive advantage in a market where technological leadership remains fluid and barriers to entry, while significant, are not insurmountable.

The fluctuations of the technology market are known to all. In the late 1990s, the first search engines on the scene did not survive in the same way as Google, which in time, has monopolised a large part of the market.

Valuation versus profitability

The central question surrounding any future IPO ultimately concerns valuation.

Much of the optimism surrounding artificial intelligence rests on expectations of future economic gains rather than demonstrated profitability. Although revenues across the sector are growing rapidly, the costs associated with model development and deployment remain high, as the continuing development of technologies continues.

This tension between growth expectations and economic fundamentals is hardly new. Financial history is laden with examples of transformative technologies that ultimately justified investor enthusiasm, but only after periods of excessive speculation and market corrections.

The comparison with the dot-com era is therefore unavoidable. While artificial intelligence already possesses practical applications that many internet start-ups of the late 1990s lacked, current valuations nevertheless reflect assumptions about future adoption, productivity gains, and revenue generation that remain difficult to verify. And, if what happened in the dot-com era is a hint a what might happen, there will likely be an initial period of instability, of the arrival and disappearance of actors, and only after several years will the markets calm down and investors gain confidence.

A test for the AI economy

Viewed in this light, an OpenAI IPO would represent more than the listing of a highly successful technology company. It would constitute one of the first major market tests of whether investors believe the AI revolution can generate returns commensurate with the extraordinary capital currently being invested in it.

While AI will more than likely be the direction of future travel, Open AI as well as the whole of the industry will have to work hard to instil confidence in prospective investors.
