“We are a small number, a happy few, we are a group of brothers.” Shakespeare’s cry of King Henry V in the face of the Battle of Agencourt could be said to be the motto of today’s artificial intelligence elites.
Last night, OpenAI announced its partnership with AMD, introducing the latter 6 Gigawatt Instinct graphics processing unit to power AMD’s AI infrastructure. The agreement includes a warrant allowing OpenAI to acquire up to 10% of AMD’s shares, highlighting the deepening of alliances across the AI hardware competition.
This is based on a $100 billion agreement with OpenAI. NvidiaThe day came on the day Figma’s stock price skyrocket after CEO Sam Altman promoted the design platform at an on-stage demonstration.
But as my US colleagues pointed out, the OpenAI and AMD arrangement adds a new direction to the increasingly cyclical nature of AI’s corporate economy, with capital, capital and computing trajectories building and driving technology among the same few companies.
Nvidia provides funding to buy tips. Oracle helps you build the site. AMD and Broadcom are entering as suppliers. OpenAI supports demand.
This is a closely intertwined circular economy, and analysts fear that if something in that chain begins to weaken, they could face serious tensions.
As the AI arms race accelerates, questions are rising as to whether this “brotherhood” can carry the expectations of the entire industry.
And, like in the battles of Ajncourt, will they be remembered as influences on the AI field rather than their numbers?

Japanese bond vigilantes strengthen fiscal easing after Takaichi Sanae wins party vote
Japan’s government bond market, which has long been protected by the Bank of Japan’s yield curve control and decades of deflation, is facing a trial of faith under Takaichi Sanae, who is expected to become Japan’s first female prime minister.
The market expects Takaichi, who won the race that led Japan’s ruling LDP on Saturday, will merge aggressive fiscal policies with still dove-based central banks in fostering growth. This combination could boost long-term yields and could potentially stem the curve of Japanese government bonds.
