Despite initial doubts, the generative AI bubble shows no signs of bursting, with investments in the sector reaching a record $56 billion in 2024. According to data from financial tracker PitchBook, this represents a 192% increase from 2023, when investors poured $29.1 billion into generative AI startups across 691 deals.

The surge in funding was driven by major raises from big-name companies like OpenAI, Anthropic, and xAI, which secured significant investments and released new, competitive products. "We aren't seeing a slowdown in generative AI funding," said Ali Javaheri, an emerging technology analyst at PitchBook. "Big names continue to secure major raises and release new, competitive products."

The fourth quarter of 2024 saw deal value soar to $31.1 billion, with the closure of massive rounds like Databricks' $10 billion Series J, xAI's $6 billion Series C, Anthropic's $4 billion strategic investment from Amazon, and OpenAI's $6.6 billion round. Mergers and acquisitions, excluding "acqui-hire" deals, accounted for a relatively small share of generative AI investments in 2024, totaling $951 million.

U.S. companies attracted the bulk of generative AI backing last year, with startups outside the U.S. securing just $6.2 billion of all 2024 VC investments in the market. However, there were some notable exceptions, including Beijing-based Moonshot AI, which raised $1 billion in February, and French startup Mistral, which secured ~$640 million in June.

Looking ahead to 2025, Javaheri warns that the generative AI sector risks becoming oversaturated with startups in similar or identical verticals. He points to the example of AI coding assistants, where no fewer than four companies – Augment, Magic, Codeium, and Poolside – closed rounds exceeding $100 million last year. This trend may not be sustainable as investor pressure to show appreciable revenue growth increases.

Technical challenges and the vast computing costs needed to stay competitive may also pose additional challenges for generative AI ventures. According to Javaheri, "only the best-funded startups can continue to keep up with the pace needed for the most innovative models." This could lead to a focus on the infrastructure layer, where companies like data center startups Crusoe and Lambda have already secured significant funding.

Investment firm KKR predicts that soaring demand for data centers to support AI will boost global spending in the sector to $250 billion a year. This could be a boon for "infrastructure layer" generative AI players, which did well for themselves in 2024.

As the generative AI sector continues to grow, it remains to be seen how these trends will play out in the coming year. One thing is clear, however: the industry's rapid expansion shows no signs of slowing down, and investors are eager to capitalize on the opportunities presented by this emerging technology.
