New York just got put on notice from the unlikeliest person.
The Big Apple's newest mayor was supposed to Make New York Great Again.
But Trump dropped a bombshell when NYSE Dallas plans hit his desk.
Trump Calls NYSE Texas Expansion "Unbelievably Bad" for New York
President Trump just handed Zohran Mamdani the worst news of his first month in office.
Trump blasted the New York Stock Exchange's plans to expand operations to Dallas in a blistering Truth Social post that exposed exactly why financial firms are fleeing the Big Apple.
"Building a New York Stock Exchange in Dallas is an unbelievably bad thing for New York," Trump wrote.
The President said the move posed a "big test" for New York's newly inaugurated mayor.
That's putting it mildly.
Mamdani just took office January 1 as America's first democratic socialist mayor of New York City.
The 34-year-old campaigned on rent freezes, city-owned grocery stores, universal childcare, and jacking up taxes on anyone earning over $1 million.
He promised to make buses "fast and free" while raising the corporate tax rate from 7.25% to 11.5%.
Bernie Sanders swore him in at City Hall while Alexandria Ocasio-Cortez led the opening remarks.
Now Trump's warning about the NYSE expansion has Democrats squirming in their seats.
Because Wall Street isn't just expanding to Dallas – it's running for its life from Mamdani's socialist agenda.
The numbers tell the brutal truth Mamdani doesn't want to discuss.
Texas now employs 519,000 financial sector workers compared to 507,000 across the entire state of New York.
Read that again.
The Lone Star State has already passed New York in total finance jobs.
Wall Street Flees to Y'all Street as Business Exodus Accelerates
JPMorgan Chase now employs 31,000 people in Texas versus just 24,000 in New York.
That's despite the bank opening a brand new $3 billion Park Avenue headquarters last year.
Goldman Sachs is building an 800,000 square-foot campus in Dallas costing $500 million.
Charles Schwab moved its headquarters to suburban Dallas.
Elliott Management decamped to West Palm Beach.
AllianceBernstein fled to Nashville.
Between 2020 and March 2023, more than 370 investment companies managing $2.7 trillion in assets relocated their headquarters.
The vast majority fled high-tax states like New York and California for Texas and Florida.
New York and California each lost firms managing close to $1 trillion in assets.
Dallas Mayor Eric Johnson sees what's happening and isn't shy about it.
"Dallas is America's first Sanctuary City from Socialism," Johnson told FOX Business.
He predicted an "avalanche of Wall Street firms moving to Dallas" under Mamdani.
"New York has a mayor who is openly hostile towards the business community and is pushing for higher taxes on job creators," Johnson explained.
The NYSE expansion announced plans to launch NYSE Texas as a fully electronic equities exchange headquartered in Dallas.
The exchange involves reincorporating NYSE Chicago into Texas.
Texas is already home to more NYSE-listed companies than any other state, representing over $3.7 trillion in market value.
The new Dallas location joins the upstart Texas Stock Exchange, which secured $161 million in funding from BlackRock, Citadel Securities, and Charles Schwab.
TXSE received SEC approval to operate as a national exchange and plans to begin trading by late 2026.
Nasdaq also announced it's opening a new regional headquarters in Dallas.
All three exchanges will operate electronically with no traditional trading floor.
Governor Greg Abbott welcomed the moves with open arms.
"Texas is swiftly becoming America's financial hub," Abbott declared after the TXSE approval.
Between 2012 and 2022, more than 361,000 California residents relocated to Texas, taking roughly $21 billion in taxable income with them.
Over 380,000 New Yorkers moved to Florida during the same period, carrying an estimated $37 billion in taxable income.
The exodus accelerated as Mamdani's election approached.
Texas has constitutionally banned financial transaction taxes and created specialized business courts specifically designed to attract capital from coastal cities.
The state offers no income tax, lighter regulations, and a governor who celebrates business rather than attacking it.
Socialist Mayor Mamdani's Policies Drive Financial Hub Migration
Mamdani campaigned promising to prove "there is no problem too big for government to solve."
He pledged "honest budgeting" while proposing massive spending increases.
But New York City ended 2025 with a staggering $380 million budget deficit.
The city's budget surplus of $97 billion in 2021-2022 has completely evaporated.
Mamdani wants to raise corporate taxes to the highest in the nation while freezing rents on roughly 2 million apartments.
He supports city-owned grocery stores run by public employees.
His plan calls for shuttering natural gas plants that supply 500 megawatts of reliable energy.
And he's proposing a wealth tax on the rich and higher income taxes to fund his agenda.
Nobody who creates wealth or jobs is going to stick around for that treatment.
Mamdani told voters "I was elected as a democratic socialist, and I will govern as a democratic socialist."
Wall Street heard him loud and clear.
The firms managing trillions of dollars are already gone or making exit plans.
Trump knows what happens when socialist mayors take over major cities.
He watched Bill de Blasio drive New York into the ground for eight years.
Now de Blasio's protégé Mamdani wants to finish the job.
Trump's warning about the NYSE expansion wasn't just commentary.
It was a prediction of what's coming for New York under democratic socialist governance.
The financial capital of America is moving to Dallas and Miami whether Mamdani likes it or not.
And there's nothing Bernie Sanders or AOC can do to stop it.
