From Google co-founder Brin spending $82m to fight a billionaire tax to Google and Meta funding a joint Super Pac, Silicon Valley is engaged in an existential fight for its political power at home

Tech billionaires have shelled out hundreds of millions of dollars ahead of the 2 June primary election in California, in an unrivaled attempt to influence who gets to run the state that Silicon Valley calls home.

The industry has used a cover-all-bases approach, funding candidates and ballot measures big and small, contributing to what looks to be the most expensive primary season in California history. The goal, experts say, is to gain both political and regulatory leverage that will perpetuate dominance in business.

Google co-founder Sergey Brin has spent $82m since January, more than any other donor, to fight a billionaire tax that’s up for a vote on the November ballot.

Democratic gubernatorial candidate Matt Mahan has received more donations than any other candidate, including from top executives at Google, Amazon, Snap, LinkedIn, Reddit and Palantir.

Crypto mogul Chris Larsen has funded three Super Pacs with $26m to sway campaigns across California, including giving $1m to back a primary candidate for state insurance commissioner.

Google and Meta have collectively funded a Super Pac with $10m to back assembly and senate candidates in local district races across the state.

Silicon Valley money is flowing toward city primaries as well as state-level ones, with tech-backed Pacs sponsoring voter guides suggesting how to vote on local tax measures.

Firm says its RTX Spark PC chip for Microsoft Windows will let AI agents replace the mouse and keyboard

• Business live – latest updates

A new front has opened up in the battle for dominance in AI chips, as Nvidia said its latest development could replace the mouse and keyboard in how people use computers.

The $5tn (£3.7tn) US semiconductor company has launched a “superchip” that puts AI capabilities into laptops and desktop computers, a move that will pit it against Intel, Apple, Qualcomm and AMD.

A new belief set is uniting some of the wealthiest men in the world around a ‘transhuman’ future – actual humanity be damned

Sam Altman, the chief executive of OpenAI, took to the Internet a few years ago to propose that homo sapiens would be the first species “to design our own descendants”. In his best case scenario, the “merge” between humans and artificial intelligence occurs at some point over the next 50 years. The alternative, where we remain simply human and the machines follow their own path, is more ominous. “If two different species both want the same thing and only one can have it – in this case, to be the dominant species on the planet and beyond – they are going to have conflict,” he wrote.

More recently, Elon Musk, the world’s richest man, who at one point last year was granted the power to reconfigure the US federal government, argued on his social media platform, X, that “it increasingly appears that humanity is a biological bootloader for digital superintelligence” – our role in the history of the cosmos reduced to that of the low level code that boots up a computer before you can run sophisticated programs on it.
