Tesla bull calls battery cost declines “good deflation” that could boost EV sales
Longtime Tesla bull ARK invest recently identified battery cost declines as a form of “good deflation” that could lead to a boost in EV sales.
To support its observations, ARK Invest used the 2022 Nissan Leaf EV’s price as an example. A few years ago, Nissan announced that the 2016 Leaf SV and SL variants would come standard with its 30kWh battery pack for an EPA-rated 107 miles of range. Nissan’s suggested manufacturer’s prices for the SV and SL were $34,200 and $36,790, respectively. ARK calculated that the 2016 Nissan Leaf would cost ~$39,000 in today’s dollars.
Today, the 2022 Leaf with a 40 kWh battery pack costs $27,400, that’s $11,600 less than the 2016 version with an additional range of 42 miles. The Nissan Leaf’s pricing reveals that it costs less to produce an EV with more milage today than five years ago.

Battery cost declines could decrease EV production costs and improve range, which may boost electric vehicle sales in the long run. An increase in electric vehicle sales could lead to growth in the EV market.
In contrast to “good deflation,” ARK also identified an example of “bad deflation” in the auto industry, specifically in the used car market. The investment management firm noted a decline in used car prices over the past few months, indicated by the Manheim Used Vehicle Index.
“While [ARK Invest] believe[s] the decline in battery costs is likely to translate into lower prices, boosting EV sales, the drop in used car prices could be signaling weakening demand for traditional gas-powered cars,” wrote Sam Korus in ARK’s newsletter.
In its July 2021 publication, The Manheim Market Report (MMR) stated there were declines in prices every week last month. The used car market saw price declines accelerating through mid-July that slowed over the last two weeks. The MMR did not differentiate between used gas-powered vehicles or second-hand cars.
However, the used car market for EVs seems to be growing. Some countries, including the United States and Canada, are already considering tax credits and rebates for second-hand EVs.
As a frontrunner in the latest EV revolution, Tesla seems to be leading the charge in the used car market for electric vehicles as well. After making headways in the new passenger car market, the Tesla Model 3 had become a dominating force in the used car market in countries like the United States and the United Kingdom.
Given everything discussed above, it seems both forms of deflation ARK Invest discussed suggest that EV sales will increase, both in the new and used car market. More governments worldwide are readily committing to decreasing carbon emissions and transitioning to clean energy sources which would greatly affect the future of the auto market as well.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.
This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.
Tesla Q2 2026 Earnings Results
- Non-GAAP EPS – $0.33 reported vs. $0.53 expected
- Revenues – $28.236 billion reported vs. $26.4 billion expected
- Free Cash Flow- -$1.092B
- Profit -$ 4.751B
Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.
Tesla shares closed today down just over 1 percent, trading at $374.01.
In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.
Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
You can stream it below. Additionally, we will be doing our Live Blog on X and Facebook.

Tesla is about to make parking in busy lots less stressful than ever
Tesla is about to make parking in busy parking lots at businesses and other points of interest less stressful than ever by allowing drivers more control over where they park and how, CEO Elon Musk confirmed on X.
Tesla has been working to improve the parking performance of vehicles utilizing the Full Self-Driving suite, but now it is looking to add more customization, allowing drivers to choose the specific space they park in, but also potentially the orientation the car pulls into the spot:
It’s coming soon
— Elon Musk (@elonmusk) July 21, 2026
Musk has reiterated on X twice over the past several weeks that Tesla is working to make things with the FSD suite based more on the driver’s specific preferences and behaviors that were seen in past drives.
Essentially, it sounds like if you tend to park away from a business to avoid other vehicles, Tesla FSD will soon recognize that preference of yours and start parking further away as well. Additionally, the prospect of assigned parking spaces has been something many owners have voiced concerns about.
Living in a community with assigned parking spaces makes using FSD incredibly difficult as it will rarely park in the correct spot when there are so many to choose from. This is also pertinent in work settings where there are sometimes assigned parking spaces.
The updates to Tesla’s Full Self-Driving suite in terms of listening to driver preferences with parking are also extending to routing. Tesla announced yesterday that with the release of its 2026 Summer Update, it was adding Automatic Navigation and Preferred Routes:

Tesla has always maintained the idea that any human input is bad input, and that, ideally, Tesla Full Self-Driving will always make the right decision. Of course, this is all in theory, but the issue is that so many of Tesla’s interventions have come because it does something that is not necessarily wrong, but perhaps not what the driver would prefer.
Taking these preferences into account will help Tesla alleviate some of the potentially unnecessary interventions that drivers perform.

Tesla starts preparing for Optimus in its smartphone app
Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.
Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:
A Dedicated “Robot” Phone Key Authentication
Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.
Tesla shows rapid teardown of Model S and X lines, paving the way for Optimus at Fremont
Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.
This is a great security feature that will eliminate at least face-value and low-level threats.
Home Data Collection and System Alerts
This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.
There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.
Other Changes
Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.
