Microsoft Corp., the biggest backer of Sam Altman’s OpenAI, and BlackRock Inc., which has an executive on the artificial intelligence startup’s board, are joining forces with one of its chief rivals.

Three months ago, Wall Street punished the world’s largest technology firms for spending enormous amounts to develop artificial intelligence, only to deliver results that failed to justify the costs.

At his party’s inaugural investment summit last week, UK Prime Minister Keir Starmer positioned himself as a champion for artificial intelligence. Appearing alongside former Google Chief Executive Officer Eric Schmidt, Starmer called AI an “opportunity,” rather than something to be scared of, and said his country “needs to run towards” it.

A French artificial intelligence startup, simply called H, has raised $220 million in initial financing from a slew of billionaires and venture capitalists on the promise of building the next generation of powerful AI tools.

Google DeepMind has released a new version of AlphaFold, a landmark tool for predicting protein structures, that puts the artificial intelligence software on a path to make breakthroughs in biology research and bolster a business that Google’s AI chief says could be worth north of $100 billion.

Industrial production is one of the dirtiest corners of the corporate world. A startup from former Google engineers thinks it can clean it up with artificial intelligence.

Twitter Inc., which is trying to defend itself against Elon Musk’s $43 billion takeover bid, has a poison pill in place, so the next obvious move on the hostile M&A to-do list is likely already being contemplated: a white knight.
