Constellation Energy plans to reopen the Three Mile Island nuclear plant in Pennsylvania

9/23/24 9:03AM

On Friday, Constellation Energy said that it has plans to reopen the Three Mile Island nuclear plant in Pennsylvania, the site of a nuclear meltdown that destroyed the second reactor at the power station in 1979.

The plant, which continued to operate safely for years after the accident, was eventually closed down in 2019 for economic reasons. But the conditions that led to its shutdown no longer hold, as demand for clean electricity soars thanks to growing demand for data centers. That has made boring old utilities stocks the best performers in the S&P 500 Index this year (chart), with Constellation Energy shares contributing significantly to that trend, having gained more than 120% in 2024.

But where are America’s nuclear power plants? We’ve mapped out the location of all 54, according to data from the Energy Information Administration.

Once operational, Three Mile Island would be the fifth nuclear power plant in Pennsylvania. Only Illinois, which has 6 nuclear plants, would have more. The rest are predominantly in eastern states, although the country’s largest is Palo Verde Station in Arizona, which has a total capacity of 3,937 megawatts — enough to power some 4 million homes.

For decades, America’s nuclear output plateaued, with new reactors in Georgia the first to be built from scratch in the US for more than 30 years. If demand for electricity to power the AI wave continues to boom, they won’t be the last.

Report: Uber considers full Delivery Hero takeover to take on DoorDash outside the US

Uber appears to be considering upping its competition with DoorDash outside the US, exploring a potential full takeover of Frankfurt-listed Delivery Hero, Bloomberg reports. Earlier this week the US-based ride-hailing service disclosed a 19.5% stake in the food delivery company, but now that could go higher.

The $11.8 billion German company could be particularly vulnerable to a takeover right now, with its CEO having recently stepped down following pressure from activist investors to sell off assets. A full acquisition would give Uber a massive foothold in over 60 countries to combat DoorDash’s European-focused Wolt unit.

Uber has been involved in a lot of deal-making of late, mostly in the autonomous vehicle space, where it now has more than 30 partnerships globally.

Uber extended its losses on the news and is currently down around 1.7%.

Meta released a Reddit dupe. Reddit investors don’t like it.

Fresh on the heels of releasing a Snapchat dupe, which sent Snap down earlier this month, Meta seems to be meddling with Reddit, quietly releasing a Reddit-like Facebook app called Forum yesterday. After news of the “dedicated space built for deeper discussions, real answers and the communities you care about,” Reddit’s stock is down 4.5% today.

Last month, Reddit’s earnings report handily beat analysts’ expectations, but it continues to struggle with the perception that bigger tech companies — including Meta — investing heavily in AI will eat its lunch. The stock is down nearly 40% year-to-date.

Report: OpenAI’s Q1 revenue was $5.7 billion, beating Anthropic

The neck-and-neck race between OpenAI and Anthropic as the AI companies barrel toward their expected IPOs this year is shaking out some internal numbers for would-be investors to ponder.

The Information is reporting that OpenAI’s first-quarter revenue was ~$5.7 billion, about $1 billion ahead of Anthropic’s revenue for the same period.

The Wall Street Journal recently reported that Anthropic is on course to more than double its first-quarter revenue of $4.8 billion to $10.9 billion in the second quarter. It is not known what OpenAI is projecting for Q2.

Recently, The New York Times reported that Anthropic’s current fundraising round seeking to raise between $30 billion and $50 billion comes with a valuation of up to $950 billion, putting it ahead of OpenAI’s latest reported valuation of $850 billion.

Alphabet’s Waymos are still getting caught in floods after recall

Waymo, the self-driving subsidiary of Alphabet, has paused operations in Atlanta after a new report of a vehicle driving into a flooded roadway and getting stuck, TechCrunch reports. The news comes just weeks after the company recalled its fleet of nearly 4,000 driverless cars to deal with a previous flood incident in San Antonio, where the service is also paused.

After that incident, Waymo instituted an “interim remedy” to make the vehicles “exclude additional operating conditions that present an elevated risk of encountering a flooded, higherspeed roadway,” but added that it was still “developing the final remedy for this recall.”

As we’ve noted, Waymo has mostly kept its rollout — now public in 11 cities — to more temperate climates, as severe weather poses more challenges to autonomous vehicles.

Report: Anthropic is in talks to use Microsoft’s custom AI chips

Anthropic is in talks to rent custom AI chips from Microsoft, according to a report from The Information, as the Claude coder’s scramble for compute continues.

During the first wave of the generative-AI boom, companies rushed to get their hands on Nvidia’s GPUs, as they were the only game in town if you wanted to build new models.

But as the role of inference has shifted to a top priority, with companies focusing on actually running models to make money, they’ve started shopping around, buying chips tailored for the task, and in some cases decided to make their own.

Additionally, Anthropic has become something of a victim of its own success at rolling out products that can be quickly adopted by enterprise clients. That rapid, wide-scale adoption has revealed significant compute constraints. Anthropic is now, effectively, looking for any and all compute capacity it can find, striking deals with CoreWeave, Amazon, Google and Broadcom, and even xAI.

Amazon and Google have both seen hot demand for their custom inference chips. But Microsoft is still trying to get its custom Maia chips into the mix, after encountering delays.

If Microsoft lands Anthropic as a customer for its Azure-based Maia computing services, it could open the door for other companies seeking another option for meeting the sky-high demand for AI inference, as agentic models gobble up trillions of tokens.
