10 Apr 2026
Chapter 1: What is the main topic discussed in this episode?
Here's your morning TNB Tech Minute for Friday, April 10th. I'm Danny Lewis for The Wall Street Journal. CoreWeave is partnering with Anthropic to run its Claude artificial intelligence models, adding another frontier AI model provider to its cloud platform.
According to CoreWeave, the collaboration will initially focus on a, quote, phased infrastructure rollout with the potential to expand over time. The cloud services provider says with the addition of Anthropic, nine of the top 10 AI model providers now use its platform.
Alibaba's new AI video generation tool is leading a global ranking that tracks models' capabilities, signaling the growing competitiveness of Chinese companies in the space. The model, called Happy Horse 1.0, has held the first place rank on third-party website Artificial Analysis's text-to-video leaderboard since the AI model was released earlier this month.
Chapter 2: What partnership has CoreWeave formed with Anthropic?
But the video generation model's provenance had been a mystery until today, when Alibaba revealed itself to be the developer. A spokesperson at Alibaba's new AI unit, TokenHub, says Happy Horse is currently under an internal beta test.
Chinese AI video players now dominate the top of artificial analysis' leaderboard after OpenAI discontinued its Sora video platform app and other video functionalities last month as part of a strategic shift. And we exclusively report that the White House warned staff not to improperly leverage their positions to place well-timed bets on prediction and futures markets.
People familiar with the matter say the White House management office sent a warning in a staff-wide email on March 24th, the day after President Trump announced a sudden pause of strikes against Iran. According to Dow Jones market data, more than $760 million worth of oil futures contracts changed hands about 15 minutes before the sudden shift in policy.
And more recently, three PolyMarket accounts earned more than $600,000 by correctly betting on the timing of this week's Iranian ceasefire. A Trump spokesman says the prohibition against insider trading wasn't out of the ordinary. PolyMarket has a data partnership with Dow Jones, the publisher of The Wall Street Journal.
