OpenAI has invested $43 million in cybersecurity startup Adaptive Security, marking its first investment in the industry.

As the AI business market expands, the demand for cybersecurity is expected to increase, prompting big tech companies to enhance their cybersecurity infrastructure through investments and mergers and acquisitions.
