• President Trump announced Stargate, a $500 billion AI infrastructure venture, on Tuesday.
• Yet Elon Musk, now a key advisor to Trump, suggested the effort has raised far less than that.
• Trump called Stargate "the largest AI infrastructure project in history."

Stargate, a privately funded effort that Donald Trump announced on the second day of his presidency, is supposed to raise up to $500 billion to build AI infrastructure in the US.

But the joint plan between OpenAI, Oracle, and SoftBank may have only raised a fraction of that so far, according to Elon Musk, now one of Trump's closest advisors.

Musk responded to a post on X from OpenAI on Wednesday. OpenAI's post said that the venture "will begin deploying $100 billion immediately."

However, Musk's response to the post said that SoftBank has "well under $10B secured" for Stargate.

In response, OpenAI CEO Sam Altman, who appeared alongside Trump at the White House on Tuesday to unveil the effort, told Musk that his claim was wrong and invited him to come see a site where the funding is already being put to work.

Musk and Altman have a tense relationship and are locked in a legal battle. Musk founded xAI, which competes with OpenAI.

SoftBank declined to comment. Representatives for Musk and OpenAI did not immediately respond to requests for comment from Business Insider.

The exchange shows discord among some of the biggest names in the tech world just a few days into the second Trump administration. Since Trump's electoral comeback in November, many tech executives have shown more interest in working with Trump than they did as he prepared to take office the first time eight years ago.

The Stargate announcement represents an early collaboration between Big Tech and Trump. The president said Tuesday that the project would make investments over the next four years, make AGI possible in the US, and create new jobs. Trump called it "the largest AI infrastructure project in history."

Asked by CNBC about Musk's claims on Wednesday, Microsoft CEO Satya Nadella shied away from confirming or challenging them.

"All I know is, I'm good for my $80 billion," Nadella said, referencing Microsoft's plan to build out its AI abilities this year using OpenAI's models.

• Short-term-rental site AirDNA revealed its new list of best places to invest in an Airbnb or Vrbo.
• AirDNA ranked cities on measures including occupancy, revenue growth, and home prices.
• Smaller spots with regional tourism and sectors that need temporary housing dominated the 2025 list.

The best place to start an Airbnb may not be a big-name destination like Jackson Hole, Aspen, or Palm Springs.

Instead, promising places to invest in short-term rentals usually have a combination of regional tourism and populations that are reliant on temporary housing, like traveling nurses or graduate students, according to Jamie Lane, an economist at analytics site AirDNA.

"The markets that do best have a mix," Lane told Business Insider.

Indeed, many of the top spots in AirDNA's new ranking of the best places in the US to invest in short-term rentals were midsize cities with affordable homes and growth potential. AirDNA evaluated places based on factors including how many nights per year current Airbnb and Vrbo listings were booked, growth in revenue per listing in the past year, and the cost of homes and apartments currently for sale.

Cracking the top 10 is Frankfort, Kentucky, a city of just 28,000 residents located an hour east of Louisville in the heart of the Kentucky Bourbon Trail — a short drive to a dozen famous distilleries, Lane said.

"While it seems like a small city, it's in the middle of a massive tourism industry," he told Business Insider.

Fairbanks, Alaska, which appeared on last year's list but jumped to the No. 2 position this year, has a robust summer travel market and a need for temporary housing for workers at nearby hospitals and a University of Alaska campus.

On a national level, the rate of new Airbnbs and Vrbos opening across the US has slowed after a post-pandemic surge. New listings grew only by 6.8% in 2024 from the year prior, compared to 14.4% in 2023 and 22.1% in 2022, AirDNA data showed.

New hosts may also face crackdowns as cities continue to rewrite the rules on short-term rentals in attempts to preserve housing affordability for locals. Lane said places including Oahu, Hawaii, were dropped from the list due to their especially tight rules for Airbnbs and Vrbos.

Here are the top 11 cities that AirDNA highlighted as the best places to invest in an Airbnb or Vrbo in 2025.

For each place, we included the projected average revenue potential, the previous year's listing growth in that city, and the annual occupancy rate, all according to AirDNA. From Redfin, we sourced each city's median sale price for homes to get a sense of how much an investment property might cost.

• Federal job offers accepted before January 20 with start dates after February 8 'are revoked,' a government memo says.
• The Office of Personnel Management said agency heads can still seek "written approval" to renew a job offer.
• Agencies must also report monthly on job offers, new hires, departures, and head count, the memo said.

Newly hired federal workers expecting to start their new jobs next month could soon see their offers yanked by the federal government.

A memo providing further guidance on Trump's executive order mandating federal hiring freezes instructed federal agencies that "offers made and accepted prior to January 20" with an unconfirmed start date or later than February 8 "are revoked."

The memo, written by the US Office of Management and Budget and US Office of Personnel Management and sent to the heads of executive departments and federal agencies on January 8, states that if individuals were hired before noon on January 20 and have a start date earlier than February 8, their offers can remain in place.

"Those individuals should report to work according to their respective designated start date," the memo said.

Even if a job offer is rescinded, it might not be a done deal for the candidate. The memo said that the head of an agency can seek "written approval" from the OPM to renew the employee's offer after considering "essential mission priorities, current agency resources, and funding levels."

The memo also calls for reports from agencies included in the hiring freeze on the last day of each month. The reports call for information about candidates who were extended or accepted offers, new employees who started that month, and employees who departed that month. The report also calls for the total staff head count and any positions listed online, the memo said.

In a separate memo sent the same day, Charles Ezell, the acting director of the OPM, asked leaders of all federal agencies to evaluate their workforces and consider firing employees who have been there less than two years.

The memo requested that agencies identify all employees on probationary periods and "promptly determine whether those employees should be retained at the agency," by January 24.

Trump's federal hiring freeze went into effect on his inauguration day, preventing any vacant positions that existed before 11:59 a.m. on January 20 from being filled, and restricting the creation of new positions. There are some exceptions to the freeze, including roles tied to "immigration enforcement, national security, or public safety" and positions requiring "Presidential appointment or Senate confirmation."

The OPM move is in line with broader Trump administration efforts to reduce the size of the federal workforce.

The Department of Government Efficiency, the Elon Musk-led commission, is also working to recommend ways that the Trump administration could cut the size of the federal workforce, reduce regulations and federal budgets, and improve efficiency.

OPM declined to comment. The Trump administration and OMB did not immediately respond to requests for comment from Business Insider.
