Solar stocks sold off overnight as investors see Donald Trump leading in the U.S. presidential election.

Solar stocks are falling on fears that a possible Trump victory would spell trouble for the Inflation Reduction Act, which has fueled a clean energy boom in the U.S. through tax credits to expand solar energy.

The benchmark Invesco Solar ETF was down 7% in overnight trading on brokerage Robinhood. The solar panel manufacturer First Solar tumbled 8% overnight. Residential solar stocks Sunrun and Sunnova fell 6% and 2.6%, respectively. Inverter manufacturer Enphase tumbled 5% and Nextracker was down nearly 5%.

Trump’s campaign platform calls for the termination of the IRA, which he refers to as the “Socialist Green New Deal.” The IRA is one of President Joe Biden’s signature achievements. The law passed on party-line vote in 2022 without any Republican support.

Trump is leading in the electoral college and is projected to win the key swing state of North Carolina, according to NBC News. The future of the IRA, however, will depend not only on whether Trump wins the White House, but whether Republicans also secure control of Congress.

Kamala Harris’ campaign chair Jen O’Malley Dillon told staff in an email Tuesday that the clearest path to victory for the vice president lies in the so-called Blue Wall states of Pennsylvania, Michigan and Wisconsin.

WASHINGTON — In the first few years after founding Coinbase, CEO Brian Armstrong shied away from Washington, D.C. But as his ambitions for his crypto exchange scaled, so too did his need to curry favor on Capitol Hill.

“About five or six years ago, we realized that crypto was getting big enough that we needed to go really engage actively in a policy effort, so I started coming out to D.C.,” Armstrong, who started Coinbase in 2012, told CNBC in September, following a day of meetings with political leaders.

Now, it’s practically Armstrong’s full-time job, and Coinbase’s money is all over the nation’s capital. The company was one of the top corporate donors this election cycle, giving more than $75 million to a group called Fairshake and its affiliate PACs, including a fresh pledge of $25 million to support the pro-crypto super PAC in the 2026 midterms. Armstrong personally contributed over $1.3 million to a mix of candidates up and down the ballot.

The tech industry’s biggest names have dotted Washington for years to try and push their agendas as their market caps have expanded, but for Coinbase, the matter is potentially existential.

SEC Chair Gary Gensler sued the firm last year over claims that it sells unregistered securities. A judge has since ruled that the case should be heard by a jury. Coinbase has fought back vociferously, and has also said that it wants to work with regulators to come up with a proper set of laws governing the nascent industry.

Meanwhile, Coinbase faces a growing list of competitors.

In the company’s latest quarterly earnings report last week, Coinbase missed on the top and bottom lines due to lower transaction revenues and a drop in subscription and services revenues. The shares plummeted 15%.

Data from CCData shows the exchange is losing spot market share to industry rivals like Crypto.com. And investors have many new options for accessing bitcoin and ethereum since the SEC greenlit spot funds this year. BlackRock’s ETF chief Samara Cohen told CNBC that 75% of its bitcoin buyers are crypto investors who are new to Wall Street.

Washington can’t save Coinbase from the competition, but the company is betting that, with favorable lawmakers in place, it can be the leader in a thriving industry rather than under the constant threat of lawsuits and Wells notices.

Armstrong said his D.C. visits normally took place once or twice a year. Then it got to be at least a quarterly occasion. And the pace has only increased.

“In the beginning, a lot of people didn’t know what crypto was,” Armstrong said of his earlier trips. Now, “the discussion has advanced, really, to, how do we pass clear rules, create legislation in the United States?”

Paul Grewal, Coinbase’s chief legal officer, attended a fundraiser in San Francisco in June that raised $12 million for former President Donald Trump. It was hosted by venture capitalist David Sacks, a former Trump critic who became an outspoken supporter when he became the Republican nominee.

Grewal later joined a fundraiser in Nashville in July for the former president.

Trump has never shown much of an aptitude for the nuances of crypto, but he’s welcomed the industry’s financial support. He was applauded in the summer, when he vowed to fire Gensler as head of the SEC if he wins.

Grewal told CNBC that he’s had “many conversations” behind closed doors with both the Trump camp as well as Democratic Vice President Kamala Harris’ campaign. Heading into Election Day on Tuesday, the candidates were in a virtual dead-heat.

“What I think we’re hearing from both campaigns is they get it,” Grewal said. “They understand that in swing state after swing state, there are enough voters who care about crypto that the candidate and their campaigns need to give voice to the concerns of those voters in supporting sensible rules for crypto, sensible legislation coming out of Congress, and that’s very encouraging.”

Grewal said that Trump “came earlier to this pro-crypto view,” but said that Harris recognizes the need for “an agenda focused on promoting sensible rules for crypto as much as any other technology.”

But Coinbase’s political interests as an organization have been focused exclusively on Congressional races, as the company looks to help assemble a group of lawmakers with favorable views of the industry.

The Stand With Crypto Alliance, launched by Coinbase last year, has developed a grading system for House and Senate candidates across the country.

In the Ohio Senate race, for example, the organization gives Democratic incumbent Sen. Sherrod Brown, who chairs the banking committee, an “F” grade, versus an “A” grade for his Republican rival Bernie Moreno, a blockchain entrepreneur. Some $40 million of crypto money has been directed at defeating Brown, and one PAC has paid for five ads designed to boost awareness of Moreno. The race is very close and is crucial in determining which party will control the Senate.

Stand with Crypto, which has enrolled 1.4 million advocates across the country, is also working to mobilize digital asset owners living in swing states. This effort involved a cross-country bus tour through battlegrounds focused on getting these residents registered to vote.

“It’s really extraordinary, given how razor-thin the margin of victory was in the 2020 election, to see crypto not only be an issue, but potentially a determinative issue in terms of the presidential cycle,” Faryar Shirzad, Coinbase’s chief policy officer, said in an interview.

Shirzad said that last year, he and his team concluded that the only way to get politics out of crypto was “to build our own political operation.” He said the goal is to “neutralization the politicization of the crypto issue and talk about it on the merits.”

Coinbase is far from alone. Nearly half of all corporate money raised this election comes from crypto firms.

Fairshake, one of the top spending PACs this cycle, told CNBC it’s raised around $170 million this election and disbursed approximately $135 million.

Ripple Labs is another one of Fairshake’s top political donors.

The company, which has spent more than $100 million battling Gensler, has given around $50 million to Fairshake. Several executives have also contributed to a mix of Democratic and Republican candidates in races across the country.

Ripple’s head of U.S. public policy, Lauren Belive, told CNBC at a fintech conference in Las Vegas that the company was motivated by the SEC’s overreach.

“We really wanted to put people into office that could learn about this technology and understand this technology, because we need Congress to act and to create federal statutes and not have this enforcement regime,” said Belive. She added the regulator has issued over 100 enforcement actions against crypto-aligned companies.

Silicon anodes appear to be leading the way in the race to commercialize next-generation battery technologies for electric vehicles.

The buzz around silicon-based anodes, which promise improved power and faster charging capabilities for EVs, has been growing in recent months — just as the hype around solid-state batteries seems to have fizzled.

It comes as increasing EV sales continue to drive up global battery demand, prompting auto giants to team up with major cell manufacturers on the road to full electrification.

While some OEMs (original equipment manufacturers) have inked deals with solid-state battery developers, carmakers such as Mercedes, Porsche and GM have all bet big on silicon anodes to deliver transformative change in the science behind EVs.

A recent report from consultancy IDTechEx described the promise of advanced silicon anode materials as “immense” for improving critical areas of battery performance, noting that this potential hadn’t gone unnoticed by carmakers and key players in the battery industry.

It warned, however, that challenges such as cycle life, shelf life and — perhaps most importantly — cost, need to be addressed for widespread adoption.

Venkat Srinivasan, director of the Collaborative Center for Energy Storage Science at the U.S. government’s Argonne National Laboratory in Chicago, said silicon anodes appear to have the edge over solid-state batteries.

“If there’s a horse race, silicon does seem to be ahead at least at this moment, but we haven’t commercialized either one of them,” Srinivasan told CNBC via videoconference.

Srinivasan said five years ago silicon-anode batteries had a calendar life of roughly one year, but recent data appears to show a dramatic improvement in the durability of these materials, with some tests now projecting a three to four-year calendar life.

Unlike the cycle life of a battery, which counts the number of times it can be charged and discharged, the calendar life measures degradation over time. Typically, the calendar life of a battery refers to the period in which it can function at over 80% of its initial capacity, regardless of its usage.

Srinivasan said solid-state batteries, long billed as the “holy grail” of sustainable driving, still have a long way to go before they can match the recent progress made by silicon anodes.

“That transition still has to be made in solid-state with their metal batteries and that’s why I think you’re hearing from people that, hey, it looks like that promise hasn’t panned out,” Srinivasan said.

“That doesn’t mean we won’t get there. It may happen in a few years. It just means that it feels like today silicon is in a different part of the technology readiness level.”

Japan’s Toyota and Nissan have both said they are aiming to bring solid-state batteries into mass production over the coming years, while China’s SAIC Motor Corp reportedly said in early September that its MG brand would equip cars with solid-state batteries within the next 12 months.

Nonetheless, analysts remain skeptical about when solid-state batteries will actually make it to market.

Georgiev said several industry players have been looking into the potential of silicon anodes, from well-established anode suppliers in China and South Korea to new players like Taiwan’s ProLogium and U.S. manufacturers Group14 and Sila Nanotechnologies.

“Especially in the West, advances in the area of silicon anodes [are] seen as strategic opportunity to catch up with China, which dominates the graphite-based anode supply chains with Chinese anode producers holding 98% of the global anode market for batteries,” Georgiev said.

“However, there are significant technical challenges going to 100% silicon anode such as silicon expansion affecting the longevity of the batteries and currently there are several routes to produce silicon anodes,” he added.

Taiwanese battery maker ProLogium debuted the world’s first fully silicon anode battery at the Paris Motor Show last month, saying it’s new fast-charging battery system not only surpassed traditional lithium-ion batteries in performance and charging efficiency but also “critical industry challenges.”

ProLogium, citing test data, said it’s 100% silicon anode battery could charge from 5% to 60% in just 5 minutes, and reach 80% in 8.5 minutes. It described the advancement as an “unmatched achievement in the competitive EV market,” which will help to reduce charging times and extend the range of EVs.

Fastmarkets’ Georgiev said a big question mark over the commercialization of silicon anodes is the cost of production and whether any of the major silicon-anode producers “could produce material at scale with a consistent quality and at a competitive price — [a] major requirements of OEMs.”

“At this stage silicon anodes are used more as an additive to graphite-based anodes and in the years to come we expect to see increase of silicon share in anode, but in combination with graphite, while 100% silicon anodes will take longer time to enter the mass market,” he added.

Saudi state oil giant Aramco reported a 15.4% drop in net profit in the third-quarter on the back of “lower crude oil prices and weakening refining margins,” but maintained a 31.05 billion dividend.

Marqeta shares tumbled more than 30% in extended trading on Monday after the company issued weaker-than-expected guidance for the fourth quarter.

Here’s how the company did compared with Wall Street estimates, based on a survey of analysts by LSEG:

• Loss per share: 6 cents, adjusted vs. 5 cents expected
• Revenue: $128 million vs. $128.1 million expected

While third-quarter results showed a slight disappointment on the top and bottom lines, Marqeta’s forecast for the current period was more concerning.

The payment processing firm said revenue in the fourth quarter will increase 10% to 12% from a year earlier. Analysts were looking for growth of over 17%, according to LSEG.

Marqeta, which primarily functions as a card-issuing platform, attributed the guidance miss to “heightened scrutiny of the banking environment and specific customer program changes.” The company has been struggling for a while, and its stock is now down more than 80% from its peak in 2021, the year it went public. The stock was down 15% for the year prior to the report.

Total processing volume of $74 billion was up more than 30% from a year earlier. Net revenue and gross profit were up 18% and 24%, respectively.

Marqeta’s digital commerce business sells payment technology designed to detect potential fraud and ensure that money is properly routed. It also issues customized physical cards that look like a credit or debit card that can be used for point-of-sale purchases.

The company has been trying to break into the buy-now, pay later business with a recently launched product called Marqeta Flex. The service brings BNPL from lenders like Affirm or Klarna to any credit card wherever Mastercard and Visa are accepted.

“It’s an orchestration layer, but it’s tied to issuing and processing and disputes and chargebacks,” CEO Simon Khalaf told CNBC at Money2020 in Las Vegas last week. “So it is not actually a Wild West in BNPL. It is actually very well established. And there is a reason why a lot of people are jumping to it.”
