Biden is going after corporate giants for being too big. Here's who he's targeted so far.

• Joe Biden's administration is going after big corporations with antitrust lawsuits.
• It's an aggressive approach that makes Biden stand out compared to his predecessors.
• High-profile cases include Live Nation, Google, Apple, Amazon, Meta, Microsoft, OpenAI, and others.

President Joe Biden is really leaning into his pro-labor image.

The Biden administration has launched investigations and antitrust lawsuits against several mega corporations, many in the tech sector, that it accuses of behaving like monopolies — and it's setting him apart from his predecessors.

"This is definitely a different agenda than previous presidents," Rebecca Allensworth, an antitrust expert at Vanderbilt University, told Business Insider. "I think that Biden is saying … consolidation and the power that large companies have gotten over the last 20, 30 years isn't good for the American consumer or for Americans in general. I think it's very much a deliberate attempt to take away on some of that market power that these big corporations have accumulated."

Big Tech leaders, even those who are typically aligned with Democrats, are not happy about it. Some have urged Vice President Kamala Harris to make changes at the Federal Trade Commission if she is elected president, namely by replacing FTC Chair Lina Khan, who has led the antitrust efforts.

Here are some of the biggest companies Khan and Biden have targeted.

Nvidia and OpenAI

Federal investigators have been given the green light to investigate the biggest names in artificial intelligence: Nvidia, the leading producer of AI chips, and OpenAI, which created ChatGPT. With a divide-and-conquer approach, the Department of Justice and the Federal Trade Commission will investigate Nvidia and OpenAI, respectively, to sniff out potential antitrust violations in the AI arms race, according to The New York Times. The FTC will also investigate Microsoft and its multibillion-dollar investment in OpenAI.

Live Nation

In May, the Justice Department filed an antitrust lawsuit against Ticketmaster's parent company, Live Nation Entertainment, which Attorney General Merrick Garland accused of "anti-competitive and illegal" business practices that have stifled innovation and led to worse experiences for fans, artists, promoters, and vendors.

Google

After a yearslong antitrust case against Google, a federal judge ruled in August that the company violated antitrust law by spending billions to keep its search engine as the default on web browsers.

Prosecutors asked the judge to implement "behavioral and structural remedies" that could include breaking up its business or reorganizing it, which would implicate other tech giants like Apple.

Google CEO Sundar Pichai said he disagrees with the antitrust ruling and intends to appeal it, a process that "will likely take many years," he said.

Apple

The Justice Department filed an antitrust lawsuit against Apple in March, accusing the company of taking over the smartphone market by "delaying, degrading, or outright blocking" the competition. The company has created a "smartphone monopoly," the Justice Department argued, using restrictive policies, accessories, and software.

Amazon

The FTC took Amazon to court last year, accusing the company of luring customers into signing up for its Prime subscriptions. The FTC claimed that Amazon "knowingly duped millions of customers." A Business Insider investigation previously found that the company was aware of its confusing sign-up infrastructure for years but did not act on it. Meanwhile, an antitrust suit brought against Amazon by the FTC is set to begin in 2026.

Meta

The FTC and dozens of states filed suit against Meta, formerly Facebook, accusing the company of buying up Instagram and WhatsApp to quash competition.

"I think there's a reason why they have one big monopolization case, at least, against each of the four major American tech companies," Allensworth told BI. "Tech is too dominant. Tech has a dangerous level of market power, and it's oppressing competition and creating products that are more dangerous and more expensive than they need to be."

The Biden administration is targeting more than just tech, however. It has also intervened in the merger of JetBlue and Spirit Airlines, which a federal judge ultimately blocked, and Kroger's bid to acquire Albertsons Companies, which is still pending following an FTC lawsuit.

Collectively, it sends a clear message to companies that "the problem goes beyond tech," Allensworth said. "Other sectors, too, suffer from concentration and could do with a bit of antitrust enforcement."

But while the administration can bring investigations and litigation, the outcome is out of its hands.

"It really lies with the courts, and the courts are not immune to political change, but less susceptible to the winds of politics," Allensworth said.
