Shutterstock are joining forces in a merger valued at around $3.7 billion, the companies announced on Tuesday. The merger will allow the companies to expand their stock photo libraries as they face increasing competition from AI-powered image creation tools.

Getty Images is the bigger company of the two, and its shareholders will own approximately 54.7% of the new entity, while Shutterstock shareholders will own 45.3%. Getty Images also owns the iStock and Unsplash brands. The company will simply be called Getty Images.

In total, Getty expects to pay $331 million plus 319.4 million shares of its stock to acquire Shutterstock. At today's share price, that works out to a valuation of about $1.35 billion on Shutterstock, or about 7% more than what Shutterstock costs after today's price spike.
