Tesla is trying to placate some solar customers who say they faced sudden price hikes earlier this year, according to new filings with the U.S. district court in San Jose, California.

In a Thursday filing, customers’ attorneys wrote, “Tesla informed counsel for Plaintiffs that Tesla had recently launched a program for customers who signed Solar Roof contracts before the April 2021 price changes to return those customers to their original pricing (if they were subject to a price increase in April 2021).”

As of Friday afternoon, further details of this program were not apparent on Tesla’s solar websites nor the Engage website for customers and advocates of the company. CNBC reached out to plaintiffs’ attorneys and Tesla to get further details about the program. They did not immediately respond.

This spring, frustrated Tesla solar customers sued the company after experiencing surprise price increases.

Filings in three separate lawsuits alleged that Tesla solar customers had already signed contracts with Elon Musk’s electric vehicle and renewable energy venture, and even prepared to have solar photovoltaics installed at their homes, when they were surprised by sudden price hikes that required additional payments to move ahead with their installations.

The price hikes were not trivial. For example, plaintiff Matthew Amans’ solar roof price shot up from around $72,000 per his original contract to around $146,000, according to lawsuit filings.

Those lawsuits were later consolidated into Amans v Tesla, Inc.

Tesla hiked prices for its solar installations at least twice early this year, and made it a requirement for customers ordering solar panels or roof tiles to order the Powerwall home energy storage system as well. Later, CEO Elon Musk revealed that the company would not be able to make enough Powerwalls to keep up with demand this year because of the ongoing microchip shortage.

Overall, solar remains a fairly small part of Tesla’s business. Tesla reported energy generation and storage revenue of $801 million in the second quarter of 2021, with a cost of revenue of $781 million for that division. The company does not break out revenue from solar on its own — the unit includes revenue from its lithium-ion battery energy storage systems, which range from home backup batteries to giant, utility-scale systems.

By way of comparison, Tesla booked $10.2 billion in automotive sales during the quarter.

Here’s the legal filing.

IONNA and Casey’s to bring more fast charging to the US Midwest

Charging network IONNA is partnering with Casey’s, one of the US’s largest convenience store and pizza chains, to bring DC fast charging to EV drivers across the Midwest.

Starting this year, Casey’s customers can plug into IONNA’s 400 kW charging stations while grabbing a slice or stocking up on road-trip essentials. Eight “Rechargeries” are already under construction in six states and are expected to open in 2025:

  • Little Rock, Arkansas
  • Vernon Hills, Illinois
  • McHenry, Illinois
  • Terre Haute, Indiana
  • Parkville, Missouri
  • Kearney, Missouri
  • Blackwell, Oklahoma
  • Waco, Texas

The Casey’s deal pushes IONNA past 900 charging bays in construction or operation — more than double what it had just three months ago. IONNA says the partnership will “expand,” but doesn’t provide specifics.

“This partnership with Casey’s is key to expanding our presence in America’s heartland,” said IONNA CEO Seth Cutler. “With a shared respect and commitment to delivering quality customer experience, we are pleased to add Casey’s to our growing network of partners.”

Google and Anthropic announce cloud deal worth tens of billions of dollars

Google and Anthropic announce cloud deal worth tens of billions of dollars

Google, Anthropic agree to cloud deal worth tens of billions of dollars

Anthropic and Google officially announced their cloud partnership Thursday, a deal that gives the artificial intelligence company access to up to one million of Google’s custom-designed Tensor Processing Units, or TPUs.

The deal, which is worth tens of billions of dollars, is the company’s largest TPU commitment yet and is expected to bring well over a gigawatt of AI compute capacity online in 2026.

Industry estimates peg the cost of a 1-gigawatt data center at around $50 billion, with roughly $35 billion of that typically allocated to chips.

While competitors tout even loftier projections — OpenAI’s 33-gigawatt “Stargate” chief among them — Anthropic’s move is a quiet power play rooted in execution, not spectacle.

Founded by former OpenAI researchers, the company has deliberately adopted a slower, steadier ethos, one that is efficient, diversified, and laser-focused on the enterprise market.

Anthropic launches Claude Sonnet 4.5, its latest AI model

A key to Anthropic’s infrastructure strategy is its multi-cloud architecture.

The company’s Claude family of language models runs across Google’s TPUs, Amazon’s custom Trainium chips, and Nvidia’s GPUs, with each platform assigned to specialized workloads like training, inference, and research.

Google said the TPUs offer Anthropic “strong price-performance and efficiency.”

“Anthropic and Google have a longstanding partnership and this latest expansion will help us continue to grow the compute we need to define the frontier of AI,” said Anthropic CFO Krishna Rao in a release.

Anthropic’s ability to spread workloads across vendors lets it fine-tune for price, performance, and power constraints.

According to a person familiar with the company’s infrastructure strategy, every dollar of compute stretches further under this model than those locked into single-vendor architectures.

Google, for its part, is leaning into the partnership.

“Anthropic’s choice to significantly expand its usage of TPUs reflects the strong price-performance and efficiency its teams have seen with TPUs for several years,” said Google Cloud CEO Thomas Kurian in a release, touting the company’s seventh-generation “Ironwood” accelerator as part of a maturing portfolio.

Claude’s breakneck revenue growth

Anthropic’s escalating compute demand reflects its explosive business growth.

The company’s annual revenue run rate is now approaching $7 billion, and Claude powers more than 300,000 businesses — a staggering 300× increase over the past two years. The number of large customers, each contributing more than $100,000 in run-rate revenue, has grown nearly sevenfold in the past year.

Claude Code, the company’s agentic coding assistant, generated $500 million in annualized revenue within just two months of launch, which Anthropic claims makes it the “fastest-growing product” in history.

While Google is powering Anthropic’s next phase of compute expansion, Amazon remains its most deeply embedded partner.

The retail and cloud giant has invested $8 billion in Anthropic to date, more than double Google’s confirmed $3 billion in equity.

Still, AWS is considered Anthropic’s chief cloud provider, making its influence structural and not just financial.

Its custom-built supercomputer for Claude, known as Project Rainier, runs on Amazon’s Trainium 2 chips. That shift matters not just for speed, but for cost: Trainium avoids the premium margins of other chips, enabling more compute per dollar spent.

AWS outage ripples across internet, puts pressure on Amazon ahead of earnings

Wall Street is already seeing results.

Rothschild & Co Redburn analyst Alex Haissl estimated that Anthropic added one to two percentage points to AWS’s growth in last year’s fourth quarter and this year’s first, with its contribution expected to exceed five points in the second half of 2025.

Wedbush’s Scott Devitt previously told CNBC that once Claude becomes a default tool for enterprise developers, that usage flows directly into AWS revenue — a dynamic he believes will drive AWS growth for “many, many years.”

Google, meanwhile, continues to play a pivotal role. In January, the company agreed to a new $1 billion investment in Anthropic, adding to its previous $2 billion and 10% equity stake.

Critically, Anthropic’s multicloud approach proved resilient during Monday’s AWS outage, which did not impact Claude thanks to its diversified architecture.

Still, Anthropic isn’t playing favorites. The company maintains control over model weights, pricing, and customer data — and has no exclusivity with any cloud provider. That neutral stance could prove key as competition among hyperscalers intensifies.

JB Straubel’s Redwood snags 0M to deploy more US-made battery storage

Redwood Materials, founded by former Tesla CTO and cofounder JB Straubel, has raised $350 million in new funding to scale its US-made battery storage systems and critical materials operations. The company is ramping up to meet surging demand from AI data centers and the clean energy sector.

The oversubscribed Series E round was led by Eclipse, with participation from NVentures, NVIDIA’s venture capital arm, and other new strategic investors.

As global supplies tighten, the US is racing to secure domestic production of critical materials like lithium, nickel, cobalt, and copper. In July, Redwood and GM signed a non-binding memorandum of understanding to turn new and second-life GM batteries into energy storage systems. Redwood launched a new venture in June called Redwood Energy that repurposes both new and used EV battery packs into fast and cost-effective energy storage systems.

Redwood says large-scale battery storage is the fastest and most scalable way to enable new AI data center rollout while unlocking stranded generation capacity and stabilizing the grid. Battery storage also helps industrial facilities electrify and balance renewable energy output. The company aims to deliver a new generation of affordable, US-built energy storage systems designed to serve the grid, heavy industry, and AI data centers, reducing dependence on imported Lithium Iron Phosphate batteries.
