Amazon has closed the account of AI educator and YouTuber Nick Saraev after he placed four orders for Nvidia's DGX Spark, and Epic Games CEO Tim Sweeney says the retailer has been canceling his orders since he tried to buy two Nvidia GPUs. Saraev posted about it over the weekend, and Amazon has not explained either case. Check out the official posts down below:
What Happened To Nick Saraev's Orders
Saraev, who has more than 500,000 subscribers on YouTube, placed four separate DGX Spark orders on Amazon last Saturday. The screenshots he shared show every order with the same message: "Your order was canceled. You have not been charged for this order." All of them were for the same listing, a DGX Spark with 128GB of memory and 4TB of storage, which sells for close to $7,000. Across the four orders, the screenshots add up to seven units.
A few hours after his first post, Saraev shared the email Amazon sent him. It reads "After a careful review of your account, we have made the final decision to close your Amazon account," and says the decision followed a verification process. Saraev said he called Amazon before the closure and was given "some vague verification shpiel." He went through the verification steps, and the account was closed anyway. In a reply to Sweeney, he wrote that he had never had problems with Amazon before and "we'd all appreciate a bit more transparency."
Tim Sweeney's Canceled Orders
Sweeney replied to Saraev's post the same day. His account is still open, but he says Amazon kept taking his everyday orders and then canceling them right before their delivery dates, starting after he tried to buy two Nvidia GPUs. He did not say which cards he ordered or how many orders were canceled.
Sweeney has been one of the loudest voices in gaming on hardware prices. Last November, he posted that "RAM price increases will be a real problem for high-end gaming for several years" because factories were moving DRAM production to AI data centers. In an interview with Edge magazine in September, he said AI companies can "outbid the entire entertainment industry for all the components" and predicted "a continual supply crisis for all gaming-relevant hardware for the next three years."
Other Buyers Report The Same Thing
X user @PurzBeats replied that Amazon "canceled the order when I tried to buy my 5090, twice." In September, a user on Nvidia's developer forum wrote that an Amazon account was hit with suspicious activity locks while trying to buy two Asus Ascent GX10 units, which use the same GB10 chip as the DGX Spark. That buyer got two DGX Sparks from Micro Center instead.
Amazon has not made a public statement about any of the cancellations or about purchase limits on AI hardware. Retailers commonly cap how many units of scarce hardware one customer can buy to slow down scalpers, and the DGX Spark has been listed as out of stock on Nvidia's own marketplace. Closing a customer's account over hardware orders is much less common, and Amazon's email to Saraev gives no specific reason.
What Is The Nvidia DGX Spark?
The DGX Spark is Nvidia's desktop AI computer. It was first shown at CES 2025 under the name Project Digits and went on sale in October 2025. The system measures 150mm by 150mm by 50.5mm, weighs 2.6 pounds, and runs on Nvidia's GB10 Grace Blackwell Superchip, which pairs a 20-core Arm CPU with a Blackwell GPU.
- Up to 1 petaflop of FP4 AI performance
- 128GB of LPDDR5X unified memory shared by the CPU and GPU
- Up to 4TB of NVMe storage
- 6,144 CUDA cores with fifth-generation Tensor Cores
- ConnectX-7 networking at up to 200Gb/s, 10Gb Ethernet and Wi-Fi 7
- 240W external power supply
Nvidia says one DGX Spark can run AI models with up to 200 billion parameters and fine-tune models with up to 70 billion parameters locally. Two units can be linked through ConnectX-7 to run models with up to 405 billion parameters. Partner versions are sold by Acer, Asus, Dell, Gigabyte, HP, Lenovo and MSI, and Micro Center carries it in the US.
DGX Spark Prices Keep Going Up
The 128GB DGX Spark launched at $3,999. In February, Nvidia raised it to $4,699 worldwide, saying on its developer forum that the change came from constrained memory supply. The 128GB model is now listed at $6,950 on Nvidia's marketplace, nearly double its launch price. Nvidia added a 64GB model in October, sold only through partners and starting at $4,999.
Gaming graphics cards are going through the same squeeze, with Nvidia reportedly charging board partners up to 30% more for GeForce RTX GPU and memory packages. For more on that, check out Ready Your Wallets, Nvidia Is Expected To Raise GeForce RTX GPU Prices By Up To 30% Amid Memory Cost Surge.
