Citi's Radke: AI splits software into winners like Microsoft and losers like Adobe

Citi's Tyler Radke says AI is splitting software into winners and losers. Radke, co-head of US software equity research, told Bloomberg Television that AI is lifting growth at Microsoft, Palantir, and Snowflake. He expects Microsoft's revenue growth to top 20%, up from 18% in the quarter ended June 30. Office costs under $100 a month and bundles security and Copilot, while rivals charge hundreds of dollars, leaving room to raise prices. Adobe and smaller application vendors face pressure as IT budgets shift to AI, he said. Salesforce agreed to buy Braze for $47.50 per share in cash. Radke questions whether Salesforce can speed up organic growth after half a dozen large deals. If financing stays costly, he expects scale to decide who survives.

US presses China to widen market access for Mastercard and Citigroup in Bangkok talks

US Treasury officials pressed China this week to widen market access for Mastercard and Citigroup, an official said. The delegation, led by Deputy Secretary Francis Brooke, met the People's Bank of China (PBOC) and the finance ministry on the sidelines of the Group of 20 and IMF-World Bank meetings in Bangkok. Regulatory approval was part of the deal reached last month between Presidents Donald Trump and Xi Jinping, the official said. Mastercard now runs yuan card payments through a joint venture with NetsUnion Clearing Corp. Approval would let it operate independently. Citigroup is seeking a wholly owned securities licence and plans to raise its China securities staff to about 100, people familiar said. It applied in late 2021. On October 13, China allowed Visa to start preparing a wholly owned domestic card-clearing business.
