With the Climate Bill that includes funding for EV buying incentives approaching its final round of voting and news about possible details on the funding running rampant, I will attempt to consolidate as much knowledge as possible into one place.
First of all, I and others here at Teslarati have written numerous articles covering EV incentives. These articles will help you understand how incentives have been voted on recently and how EV incentives in the US compared to the rest of the world. Some of the most notable include this article about US State level EV incentives, this article about how the “union made” incentive was scrapped earlier this year and this opinion piece about what Elon Musk thinks about EV incentives and how he hopes the US will move away from ICE vehicles.
A personal favorite from outside of Teslarati, Martyn Lee of the EV News Daily podcast has laid out a couple of perspectives from Twitter in one of his most recent episodes.
Martyn does a fantastic job of laying out a couple of perspectives on the EV incentives, how some are proposing to pay for them, and reading from experts examining the bill. One such expert is Tom Randall of Reuters, who has posted numerous Twitter threads on the topic. His most notable is the one linked below, where he covers the basics of incentives, who will qualify, and other notes surrounding the legislative process/votes.
Interesting EV tax credit details in the new Manchin deal: $7.5k credit per new vehicle and $4k for a used EV (or 30% of price, whichever is less). The credits expire at the end of 2032—with no manufacturer caps. A bunch of new limitations include ?1/

Some important notes from the thread are that used cars will also qualify for a tax rebate of up to $4,000 (as long as your salary is below $75,000 individually or $150,000 for joint filers), and new cars will only qualify if they are under $55,000, new SUVs and trucks will have to be below $80,000, and used vehicles must cost less than $25,000 to qualify.
For those who need a consolidated explanation of what will allow a vehicle to access the incentive, u/mad691 on the r/Electric Vehicles subreddit has posted a spreadsheet that includes all current plugin models and their possible federal rebates if the bill, in its current form, passes. The sheet consists of the qualifications that manufacturers must meet for customers to access the tax rebate along the top row.
Listed on the left are the current incentives available for each model. Then the following five columns highlight whether the vehicle may qualify in the future under the new proposal. These qualifications would disqualify the vehicle from the incentives. Finally, on the right are two columns that highlight the possible rebate of the vehicle and the change in rebate from the current system (red being negative, black being positive change).
Possible Federal EV Incentives from u/Mad691 on Reddit
While the sheet is not fleshed out completely, especially looking at the battery material clause and battery component clause columns, it can at least give a sense of what vehicles may qualify and which may not. Any of the three middle columns (Car Price, Truck+SUV Price, and Assembled in America) are instant disqualifiers and represent the vast majority of disqualifications from the incentives.
Some surprising results from the table include GM’s offerings that would once again be available for the rebate, the laundry list of vehicles not assembled in the US that would no longer qualify for the tax credits, as well as the long list of PHEVs that will continue to receive the full $7,500 in tax credits despite small batteries and lackluster fuel economy (specifically looking at the Jeep Wrangler 4xe with 14 miles of EV range and the BMW X5 with 30 miles of EV range).
This news should be taken with a huge grain of salt as voting and editing the bill have not yet been completed. However, it can give a basic understanding of what incentives may become available if the bill were to pass.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
