A tech tycoon whose parents fled communism has issued a dire warning about a looming dystopia under the leadership of New York City's new mayor Zohran Mamdani.

Antonio García Martínez, director of app building platform Base, fears the Big Apple will see a surge in crime, anti-Semitic attacks and further insolation among its wealthiest citizens.

The San Francisco native is in the process of relocating from California to New York but warned that his new home may soon look eerily similar to the hellish scenes at home he is eager to escape.

San Francisco has suffered from soaring crime, homelessness and open air drug use which has been exacerbated by a series of liberal policies.

Martínez sounded the alarm on Mamdani as 'prognostications from someone who saw this movie in SF', suggesting he fears the city will end up like his home.

He predicted rent will skyrocket, the quality of public schools will diminish and that the local media will be 'flying cover for all of it'.

Martínez shared his terrifying prophesy on social media just minutes after Mamdani was officially declared mayor-elect.

'Great time to mention that I've officially given up on the SF home search, and am moving to NYC to be closer to the Base team,' Martínez tweeted Tuesday night.

'My parents might have fled communism, but I'm moving to newly-elected socialism to work on onchain hyper-capitalism. Man plans and God laughs.'

He said he was abandoning real estate shopping in San Francisco because it was 'too expensive, too much hassle' and was 'not even sure I want to be here long-term.'

But he also disclosed his apparent fears for the city he will soon call home. 

Citing the crime way that has ravaged the Bay Area lately, Martínez warned that under Mamdani's leadership New Yorkers can expect a rise in unfettered shoplifting, car break-ins, assaults and all types of criminal activity.
