Big Tech’s experiencing growing conservative support that could change the tide.

Public support for Donald Trump used to be scarce in Silicon Valley, the land of tech billionaires, but something of a systems reboot is taking place.

“Nobody’s excited about Biden right now,” claimed David Sacks, an influential investor, on his popular All In podcast. “There’s a lot of people who I do think support Trump.”

The billionaire venture capitalist is holding a fundraiser for Trump at his mansion on “billionaire’s row” in San Francisco on Thursday evening.

He acknowledged the fundraiser in a post on X, formerly Twitter, that also included an endorsement of the former president.

Mr Sacks wrote that he believed that "the Biden administration has veered badly off course" and that "President Trump can lead us back".

Tickets for the event at his home are reportedly selling for up to $300,000 (£234,000). It is Trump's first fundraiser since being convicted on all 34 criminal charges in the New York hush-money trial.

The event has drawn controversy in the famously left-wing American city.

A 10-metre (33 foot) inflatable chicken that bears a passing resemblance to the former president and sports a striped prisoner’s uniform was there to greet him mockingly when he arrived to drum up dollars for his current presidential run.

Tech entrepreneur Jason Calacanis, who co-hosts All In and does not support Trump, said he's getting "crucified" by friends asking why he associates with Mr Sacks.

California was once a red state, home to Republican presidents Ronald Reagan and Richard Nixon, but a Republican presidential candidate has not won here since the 1980s.

Loyalty to the Democratic Party is still the most common currency among the titans of tech.

But a red tide - or at least a ripple - may be coming, fuelled by local frustrations, and emboldened by pro-Trump billionaires like Elon Musk.

The tech entrepreneur and richest man in the world, according to Forbes, helped usher Trump back onto X after he purchased the platform formerly known as Twitter.

The reason for the support of the tech executives is varied. Some see him as the ultimate “disrupter,” a term often used in Silicon Valley to describe out-of-the-box leaders. Others fear President Biden’s proposal to raise taxes for the uber-rich.

There is also the issue of regulation. Although Big Tech has enemies in both parties, the clamour to introduce stricter rules on competition and privacy has in recent years been louder among Democrats.
