Nvidia Invests in OpenAI With $100 Billion to Build Out More AI Data Centers
The first gigawatt of Nvidia systems will be deployed in late 2026 as the push for more and bigger AI infrastructure continues.

OpenAI and Nvidia have struck one of the biggest partnerships in AI, with Nvidia pledging to invest up to $100 billion in OpenAI while supplying the compute power needed to build the company’s next generation of models.
The deal, announced Monday in a letter of intent, calls for OpenAI to deploy at least 10 gigawatts of Nvidia systems for AI data centers over the coming years. The first phase, one gigawatt, is scheduled for the second half of 2026 on Nvidia’s upcoming Vera Rubin platform, named for the late dark-matter astronomer. Nvidia’s investment will grow in scale as each new system is deployed.

«Everything starts with compute,» said OpenAI CEO Sam Altman in a statement. «Compute infrastructure will be the basis for the economy of the future, and we will utilize what we’re building with Nvidia to both create new AI breakthroughs and empower people and businesses with them at scale.»

This partnership is notable as AI research is increasingly constrained by access to massive computing resources. By securing a long-term pipeline of Nvidia hardware, OpenAI seeks to guarantee its ability to keep pace with rivals like Google, Anthropic, Microsoft and Meta.
For Nvidia, the deal makes it more than just a supplier. By gradually taking a large stake in OpenAI, it positions itself at the center of the AI boom, buying into the biggest AI company.
«This is the biggest AI infrastructure project in history,» Nvidia CEO Jensen Huang said in a statement.

The completion of this deal will take years. If the partnership holds, it could define how quickly AI advances, what kinds of models OpenAI can deliver in the future and how accessible those models will be to the global population.
OpenAI is already using Nvidia systems in its Stargate I data center, a sprawling facility in Abilene, Texas, that is still under construction.

Microsoft’s Gaming Copilot AI Now Can Help You Beat That Tough Boss on PC
Gaming Copilot won’t play the game for you but it will give you advice.
Microsoft’s Gaming Copilot, a beta AI assistant meant to help gamers, is out now on PC and will come to the Xbox mobile app next month, the company said in a blog post on Monday. Microsoft says Gaming Copilot will launch on PC gaming handhelds, like the ROG Xbox Ally and Xbox consoles in the near future.

Gaming Copilot is still in beta and is available to users 18 and older and in all regions except China. Players can ask Copilot questions using the AI assistant’s voice mode for recommendations, help and other insights.
PC players will now see Gaming Copilot in the Game Bar, an on-screen overlay that you can call up during a gaming session. Gaming Copilot launches next month on the Xbox app for iOS and Android.
With voice mode, you can have a conversation with Copilot about your gaming, asking for tips and guidance on quests or boss battles. There’s a push-to-talk feature that lets you assign a key to quickly bring up Gaming Copilot. It’ll also be possible to pin a Gaming Copilot widget on-screen, which Microsoft calls Mini Mode, to interact with the AI assistant.
«When you ask Copilot a question, it combines this understanding with your player activity on Xbox and public sources of information from the Bing search engine for its response,» a Microsoft spokesperson said in a statement. «We are also working on a way for creators to contribute and curate the information that Gaming Copilot shares for their games.»
It’s uncertain if Gaming Copilot is pulling information from game guides found online, on sites such as CNET’s sister site IGN, Polygon or The Gamer. Writing game guides is often time-consuming and labor-intensive. These sites gain a substantial amount of traffic through guides, however, often via search engines. AI giving users answers directly could eat away at this significant traffic driver.
With Microsoft investing heavily in AI, throwing $13 billion into ChatGPT-maker OpenAI, the company is finding ways to put the technology in everything from Windows to Notepad. AI is also helping Microsoft’s Google Search competitor, Bing.
Microsoft’s continued AI investments, along with its strong cloud support and dominance in enterprise, led Wall Street to shower the company with support. AI hype, along with other factors, helped propel Microsoft to a $3 trillion valuation last year.
(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)
Microsoft Research also showed off a new AI model, Muse, that could generate gameplay visuals, mainly for video game ideation.
How to use Gaming Copilot on PC
- Install the Xbox app on PC.
- Press Windows + G to open Game Bar.
- Click on the Copilot icon.
- Log in to your Microsoft account for full functionality.
How to use Gaming Copilot on mobile
- Install the Xbox app.
- Tap on the Copilot icon.
- Begin conversing with Copilot. It should sync with the game you’re playing on PC.

We Found the 7 Best Places to Sell Your Used and Unwanted Electronics in 2025
Your old tech devices don’t have to go in the trash after an upgrade. We’ve found the top marketplaces that will pay you for your used electronics.
What to consider
Know the value
Before you decide to sell, you can check any trade-in service to get an idea of the value of your electronics.
Check multiple services
There’s no such thing as one price. Check around at multiple trade-in stores to see if the value changes.
Beware of scams
Only sell your electronics at places with buyer and seller protections so you can keep your cash.
Be honest
If you aren’t totally honest about the condition of your device, you won’t get the kind of money you thought you were going to get.
Technology is constantly evolving, and companies are always pushing new and more innovative gadgets. If you want to keep up with the latest wave of tech, you’ll need to upgrade often, from iPhones to wireless earbuds. And that’s definitely true right now following Apple’s recent iPhone 17 and AirPods Pro 3 releases. But what happens to our old devices when we upgrade to something new and shiny? Usually, they just end up cluttering our drawers. From previous-gen phones to old headphones and aging gaming consoles, we all have stuff we no longer use, taking up space we don’t have.
The good news is that retired devices aren’t entirely useless. Several online marketplaces exist where you can sell them for a few extra bucks. If you’ve recently upgraded to a new phone, replaced your laptop or want to save up for a new one, selling your unwanted devices can be a great way to declutter and make some money. And if a gadget still works, you can also consider trading it for a discount on a new one.
Selling your old gadgets is a smart move. Even if you don’t plan to buy something new right away, having a little extra money never hurts, and recycling responsibly is a bonus.
From Apple gear and smartwatches to gaming consoles and fitness trackers, I’ve rounded up the best places for you to sell used electronics. These services offer competitive rates and various ways to cash in, whether you’re looking for trade-ins or straight-up payments. Our team at CNET has personally used many of these platforms, giving us a solid foundation to help you choose the right one.
What is the best place to sell used electronics?
Regarding value, ease of use and knowing you’re protected against scams, Swappa is one of the best options out there. There are some great options available if all you want to do is put your phone or tablet in a box and get paid a few days later but if your goal is to make the most money and do so quickly, you’ll find this is the ideal option.
Swappa allows you to list your own tech at whatever price you think is fair, and the company helps you make that decision by giving you a look at what other versions of your products are selling for. When you sell on Swappa, you sell directly to another person. If someone is interested in making a purchase but would like additional photos or details, they can request them directly from you.
When it’s time to make a purchase, Swappa ensures you are paid quickly and the buyer is assured that you’ll ship the product promptly. Everyone wins and the Swappa staff are involved in the whole process to avoid scams.
Best places to sell used electronics for 2025
Pros
- Very few limits on hardware you can sell
- Extremely helpful staff
- Protections for buyers and sellers
- Quick payout
Cons
- Frequently requires negotiating with the buyer
- PayPal-only
Where many of the other services on this list have you send hardware to them for evaluation and payout, Swappa is a direct-to-consumer service. You list the hardware you want to sell with photos and whatever price you want to start at and, once the listing is approved by staff, you’ll be listed for any buyer looking to make a purchase. If you’re buying, Swappa is sure to enforce timelines on shipping and payment so everyone is treated fairly. While this method requires a little more work on behalf of the seller, the result is frequently a much higher payout and the Swappa team protects both sides of the transaction from any shady behavior.
Pros
- Quick payout
- Decent seller protections
Cons
- Amazon-only payout
- Limited hardware accepted
Amazon’s trade-in program works a lot like its retail store. You do an easy search for an electronic item, enter any necessary details (storage, screen size and so on) and then select the device’s condition. Amazon will then make an offer for your electronic gadget and, if you accept it, provide a free shipping label for the item. The number of items Amazon accepts spans a wide spectrum, including video doorbells, wireless routers and other home security devices.
Once you ship the item, Amazon will inspect it to ensure the item matches your original description. If it all checks out, your Amazon account will be credited with an Amazon eGift card for the offer amount. If the item is in better condition than you described, Amazon’s customer service promises to pay you more. If you’d rather trade in a device in person, Amazon has a list of locations where you can take Amazon devices and select phones. Amazon states that even nonworking devices can be accepted. The drawback? Your money is sent exclusively to your Amazon account.
Pros
- Multiple payment options
- Great hardware library
Cons
- 2-day shipping costs more
Unlike the previous services for selling electronics online, ItsWorthMore will pay you through your choice of PayPal, Zelle, gift card or an old-fashioned paper check. The process for selling electronic goods entails answering some questions about the old cell phone, tablet, Apple Watch (or other Apple device) or computer you’re selling. ItsWorthMore will then give you an offer and, if you accept it, provide you with a prepaid shipping label. During the checkout process, you can select how you want to receive your payment.
You also have the option to pay $15 for two-day shipping as well as a 24-hour processing time. Otherwise, standard shipping and a turnaround target time of 72 hours. Processing can take up to five business days. When your device is received, ItsWorthMore will verify if the indicated working condition is accurate, which means checking whether it’s in good condition, fair, broken and so on. If there’s a discrepancy, you’ll have a chance to ask for the device back or accept the revised offer.
Pros
- In-store experience is super convenient
- Recycling options are available if the value is low
- Many kinds of hardware accepted
Cons
- Best Buy gift card only
Getting a quote from Best Buy is as simple as picking a product category, manufacturer, model and condition. Once you’ve filled out the questionnaire, the tool will estimate the unwanted device and give you an instant quote. The offer amount, if you choose to accept it, will only be awarded as store credit in the form of a Best Buy gift card. The company lists a handful of stores that don’t participate in the trade-in program.
Best Buy’s payment turnaround time is slower than other services, but the company accepts a wider variety of gadgets, matching nearly every type of electronic device it sells. This includes various laptop options, smartphone options, wearables, digital camera options and video game consoles. You can trade in your gaming system, video games and an iPhone or iPad at the same time, for example.
Pros
- Fast turnaround after a quote is made
- Custom quotes for unlisted hardware
- Multiple payout options
Cons
- Offer adjustment process after delivery can take a while
BuyBackWorld will buy a range of products, including phones, tablets, iPods, cameras, game consoles, computers, headphones, drones and more. You can even get a custom quote for products that aren’t listed on the site. After getting a quote and selecting how you want to be paid, send your items to BuyBackWorld. Once they receive your shipment, they’ll inspect your items and you’ll get paid. If the quote is adjusted after inspection, you can accept the new offer or have your device returned to you.
Pros
- In-store experience is convenient
- In-store recycling is helpful
Cons
- Apple gift card only
- Limited non-Apple trade in opportunities
Apple’s trade-in program will take devices from a range of companies, not just its own. Currently, Apple will accept your laptop, smartphones, tablets, watches and «other» devices and old equipment. If the company doesn’t have a trade-in offer for your device, like iPods or AirPods, Apple will recycle it free of charge. Apple states it will take two to three weeks to complete the online trade-in process.
If you want to place your order for a new device right now, the company will credit your payment method with the trade-in value once it’s processed. Alternatively, if Apple Stores are open in your area, you can visit the store and get an instant store credit for your trade-in. It’s especially helpful with the launch of the iPhone 16. Using Apple’s trade-in service makes sense if you’re already planning on buying a new iPhone or Mac. It’s not a worthwhile option for someone who wants to buy the latest Samsung Galaxy, for instance.
Pros
- Many hardware types accepted
- Direct Deposit payments
Cons
- Turnaround time is a little long
BackMarket makes it very easy to trade in your old gear for cash in your account, quickly. The company accepts phones, tablets, game consoles, and even headphones with payouts of up to $700 depending on the product and its condition. Getting started is quick and easy, all you have to do is answer a few questions and then you’ll see the offer. If you accept, you ship your device out (which is free), and then once it’s inspected they send you the money.
Factors to consider when selling your used electronics
Know the value: Nearly every service will tell you the value of your tech before you actually list it, by asking a series of questions about the current state of your tech. Using any of those services will let you know what you can expect to make before you make any decisions.
Check multiple services: Every service offers a different price for just about everything, and while most of the time those differences are only a couple of dollars in either direction, you will occasionally find significantly better offers depending on the time of year. For example, if you’re selling a phone, its value is typically at its highest just before a new phone is released.
Beware of scams: If you’re using a service that lets you talk directly to a person who might be buying, it’s important to keep that conversation on the service you’re using. Don’t start separate conversations, especially if that person is promising to pay you more or help you avoid seller’s fees.
Be honest: If your tech has some scratches or damage, be sure to claim this damage. Failure to do so will end in not getting the amount you were promised, and in some cases, can result in your getting banned from selling other tech in the future.
Used electronics FAQs
Are used electronics worth anything?
Broadly speaking, if you have something less than five years old and it’s in good condition, there’s a good chance you could sell it. With smartphones and tablets, anything made by Apple tends to sell for more, even when it’s slightly older.
What do I do if I can’t sell my used electronics?
If you’ve looked up the value of your tech and it’s not much, but you still want to get it out of the house, you can still recycle that tech responsibly instead of throwing it away. We recommend using the Best Buy recycling service, which can be used in the store or online.
What if my used electronics have swollen or damaged batteries?
If you’re trying to get rid of something with a swollen or puffy battery, please do not throw it away or attempt to ship it to a sales facility. Swollen batteries represent a significant fire risk and should be disposed of quickly and correctly. The best way to do this is to look up e-waste facilities in your area and safely deliver either just the battery or the whole device to that facility.
