Bankers Say Megadeal Window Is Narrowing After Democratic Midterm Wins

The Democrats' rout in the midterms has boardrooms treating the current merger-friendly regulatory climate as something with an expiration date. Executives are wondering if they might have one last chance to pull off a transformational transaction while M&A-friendly regulators remain in place under Trump.

The argument comes from the people who get paid to put deals together. Kevin Foley, co-head of investment banking at JPMorgan Chase, said companies should be ready to transact through another complicated operating environment.

"The biggest risk may be assuming that, sooner or later, things go back to normal," Foley said. "Standing still is always an option, but when industries are changing this fast, it's the wrong one."

Fernando Rivas, a senior Wells Fargo banker, was blunter at an industry conference in Boston on Thursday. He said a "now or never" mentality will return to drive M&A in the near term.

The numbers behind the rush

Trump's two terms account for an outsized share of the biggest deals. More than half of all announced transactions worth at least $50 billion that involved a U.S. company over the past two decades came while he was president, according to analysis of Bloomberg-compiled data.

This year's list is already long. Marvell Technology agreed this month to buy laser maker Lumentum Holdings in a takeover reported at $100 billion-plus, with other coverage putting the figure at roughly $115 billion. The Department of Justice cleared Paramount Skydance's $110 billion acquisition of Warner Bros. Discovery without antitrust remedies.

That second one matters for the argument bankers are making. A $110 billion media combination passed federal review with no remedies attached.

Why the clock matters

Megadeals can take months to negotiate and even longer to clear regulatory reviews around the world. Paul Nary, an assistant professor of management at the University of Pennsylvania's Wharton School, laid out the timeline.

"If you have a major transaction that is going to take time to put together and get through the process, you really have to start working on it now and probably announce it by the middle of 2027," Nary said. "There isn't that much time left."

His concern is the calendar. Companies that wait until a 2028 presidential campaign is in full swing risk seeing their deals become political footballs at the stump.

The bankers' premise is that a resurgent Democratic Party could work to frustrate the kind of blockbuster dealmaking that built up steam during Trump's second term. That is a forecast, not a policy.

Democrats will not take control of the Department of Justice or the Federal Trade Commission, leaving the administration's merger enforcers in place. But gaining control of both chambers of Congress will give the party new ways to interrogate large and sensitive M&A through hearings, investigations and subpoenas, as well as stoking public scrutiny of companies and regulators. Several large deals in the pipeline, and even some that have completed, could become early targets for the new-look Congress from January.

DoorDash's $17 billion takeover of Instacart parent Maplebear has drawn criticism from prominent Democrats including New York City Mayor Zohran Mamdani. Senators Ed Markey and Richard Blumenthal have targeted NextEra Energy's $67 billion purchase of Dominion Energy, warning it could reduce competition and raise costs for consumers. Senator Cory Booker has vowed congressional oversight to dissect the Paramount-Warner Bros. deal, which closed last month.

Paul Humphreys, global co-head of industrials at law firm Freshfields, said Congress will not investigate every transaction. "I would expect the focus to be on particular themes, especially affordability and accountability," he said. He added that Congress can call executives in, issue subpoenas and put a transaction under a political spotlight even after it has been cleared.

Not everyone on Wall Street is bracing. Brokerages said the recent AI selloff was overdone and downplayed the risk of Democratic regulation, according to a Nov. 9 report.

Marvell-Lumentum is the first real test

The Marvell deal is the obvious case study, and the market is not treating it as settled. Analysts put the odds of the deal closing near 50%, according to Bloomberg and Benzinga reports from Nov. 9 and 10.

The Motley Fool pointed to a gap on Nov. 6: Marvell agreed to pay $1,132 a share, while Lumentum stock was trading near $510. Barron's said both stocks were headed for historically bad weeks after the announcement.

Lumentum was up 15% in a broad technology rally on Wednesday after CoreWeave's earnings revived the AI trade.

There is also a trade-policy wrinkle in the same sector. Microsoft is asking the Trump team to drop an expected ban on Chinese optical transceivers used in AI data centers, according to reports on Nov. 10. Lumentum sits in the optical supply chain.

SpaceX and Tesla

Bloomberg flagged a possible SpaceX-Tesla combination as a major test of mega M&A in the new landscape, one that would be among the biggest and most politically sensitive corporate tie-ups ever attempted. Bloomberg News has reported that Elon Musk, who spent almost $500 million supporting Republican candidates in key midterm races, is pushing to announce a merger of his two largest companies by the first half of 2027. Shares in both SpaceX and Tesla have slumped amid concerns that a Democrat-led Congress will probe Musk's business and political dealings and look to slow the AI boom. Observers are watching for formal announcements from either company.

What to watch

The next marker is whether companies actually announce big deals before mid-2027, the timeline Nary gave. The Marvell-Lumentum review is an early test of how much weight regulators and the market give to the changing political map. With roughly even odds on that deal closing, the answer is still open.
