AI investment reshapes markets

Artificial intelligence has established itself as the engine of a global cycle of investment and infrastructure that is reshaping capital markets, according to a report from Bancolombia published by Bloomberg Línea on October 8, 2026. Unlike the technology euphoria of the late 1990s, this boom rests on solid financial foundations and a massive mobilization of private corporate capital.

The phenomenon operates through a feedback loop in which large technology corporations demand unprecedented processing capacity. This drives investment in data centers, microchips and power grids, transforming the basic infrastructure of the global economy. The magnitude of this spending is reconfiguring valuations on stock exchanges and pushing software development firms to seek financing in primary markets.

According to data published by Bloomberg Línea, the technology industry mobilized $406 billion in 2025, with projections of reaching $770 billion in 2027. For its part, the International Monetary Fund estimates that private investment in this technology could exceed $2 trillion in 2026. This flow is highly concentrated: just five firms (Oracle, Microsoft, Meta, Alphabet and Amazon) absorb 81% of investment in the global technology ecosystem.

This level of spending is equivalent to about 1.6% of US GDP, according to estimates from the asset manager GMO. To finance this expansion, companies are turning to capital markets. Bloomberg Línea reported that Anthropic is considering an initial public offering of up to $100 billion, while OpenAI expects to raise at least $60 billion to sustain its advanced model development operations.

In the medium term, it will be worth watching whether this pace of capital investment, projected at $830 billion for the nine largest cloud providers in 2026 (a 79% annual increase), translates into real productivity gains for the rest of the economic sectors, or whether it deepens the digital infrastructure gap between advanced and emerging economies.
