Vistra Plunges 14% as Democratic Sweep Hits Power Stocks

Vistra shares fell more than 14% on Wednesday, on track for their lowest close in more than 18 months, as a Democratic midterm sweep triggered a broad selloff across power stocks. NRG Energy dropped 11% and Constellation Energy slid 6% in sympathy.

The slide hit independent power producers hardest — companies Wall Street had cast as eventual winners from AI-driven electricity demand and rising power prices. Investors now worry that newly elected officials will slow the data-center buildout and tighten regulation on the energy sector.

Raymond James analysts called the Democratic sweep of Congress "a significant policy shock" that adds "considerable" uncertainty to the artificial-intelligence buildout. Still, they cautioned against an "excessive knee-jerk selloff."

"We remain constructive on the longer-term electricity and natural-gas demand opportunity, but the timing, geography and economics are increasingly uncertain," the Raymond James analysts said.

Why did Texas stocks take the biggest hit?

Much of the sharhest damage concentrated on power producers exposed to ERCOT, Texas's grid operator. In Texas, Gina Hinojosa defeated Gov. Greg Abbott to become the state's first Democratic governor in more than 30 years and its first Latina governor.

Wells Fargo analysts noted Wednesday that Texas hosts about 20% of the cumulative U.S. data-center pipeline and close to 30% of planned gigawatt additions through 2028. Hinojosa campaigned on a pledge to hold off on new data centers until the state legislature meets in January. Abbott had already halted permit approvals pending state-agency reviews.

Texas, alongside Virginia and California, leads the nation in operating data centers and planned facilities. Data centers have grown unpopular across the political spectrum, with winning candidates campaigning on affordability and infrastructure concerns tied to their growth.

Is the demand thesis actually dead?

Not according to Evercore ISI. The common state-level policy thread is more about cost allocation — large energy consumers paying 100% of their power consumption — than a rejection of load growth, the firm's analysts said.

"We read the result as a pace-and-returns risk including moratoria, permitting pauses, fixed-charge and potentially [return on equity] pressure rather than a reversal of the demand thesis," the Evercore ISI analysts said.

Ira Joseph, a senior research associate at Columbia University's Center on Global Energy Policy, told MarketWatch that Texas has always pursued a pragmatic, "all of the above" energy policy.

"Data-center demand growth in West Texas, which is not a particularly populated area of the state or of the country, will continue to move ahead," Joseph said. If you're building data centers, it makes sense to build them as close to the generating fuel source as possible, he added.

Joseph said newly elected Texas politicians are unlikely to change oil and gas policy, with the possible exception of stricter rules on flaring and venting for natural gas.

What does the sweep mean for oil?

The election also moved crude markets. Renewed expectations of a peace deal pushed Brent futures, the global benchmark traded in London, down more than 8% on Wednesday.

Joseph said the Democratic sweep could affect issues around the war with Iran — and by extension global oil and gas production. "There's going to be more pressure on the administration to end the war, make peace and solve some issues," he said. The same applies to the Russia-Ukraine conflict, he added.

RBC analysts said they don't believe the Trump administration's Iran policy will shift "materially" despite Republicans losing both chambers. The administration "likely keeps the blockade and threatening strikes while testing if latest diplomatic attempts can land a deal" — swapping some control over the Strait of Hormuz for nuclear constraints, they said.

"If Iran stays rigid, escalation to break the stalemate is more likely than not," the RBC analysts said, likely through "surgical" strikes. Democrats could cut war funding, but lame-duck Republicans will probably increase defense spending before January, they added.

"History suggests Congress won't defund the war either — during the Iraq war, Congress never cut funding despite voting to end it, and Bush deployed troops even after losing both chambers," the RBC analysts noted.

TD Cowen analysts see crude settling into a "higher-for-longer" regime regardless. "We see crude-oil markets settling into a 'higher-for-longer' regime, with fair value for Brent crude oil remaining in the $90-$100 [a barrel] range, and potential for upside via risk premium so long as the Middle East and Russia-Ukraine conflicts remain unresolved," they said.

The chip side of the AI trade took its own hit Wednesday, with Micron and other semiconductor stocks slipping as election results struck at data-center optimism.
