Nvidia’s (NVDA) billion-dollar strategic partnership with Nokia (NOK) sent Nokia shares up over 20% on Oct. 28, hitting their highest level in more than three years. But perhaps the real winner was named deeper in the press release: T-Mobile (TMUS).

Nvidia, already the world leader in chips crucial for artificial intelligence, wants to make its technology central to everyday life.

This week’s big rally in Nokia Oyj shares underscores how the 5G equipment maker and once-iconic phone brand is now emerging as a major European artificial intelligence play.

Nvidia will pay $1 billion for a 2.9% Nokia stake as part of a deal focused on AI and data centers, the Finnish telecom equipment maker said on Tuesday as its shares hit their highest level in nearly a decade.
