Update, September 4, 5:15PM ET: NVIDIA has denied Bloomberg's report. Speaking to CNBC, the chipmaker said that it had inquired with the US Department of Justice and has not been subpoenaed. It added that it was "happy to answer any questions regulators" have about its business. The headline of this story has been changed to reflect this denial. The original story follows unedited.

The DOJ has sent subpoenas to NVIDIA and other companies as part of an antitrust probe, as reported by Bloomberg. The federal government is seeking evidence that the company violated antitrust laws with regard to its AI processors. The presence of these subpoenas means the DOJ is one step closer to launching a formal complaint.

Officials speculate that NVIDIA is making it difficult for other companies to switch hardware suppliers and that it “penalizes buyers that don’t exclusively use its artificial intelligence chips.” This probe started in June, but recently escalated to include legally binding requests for information.

At the root of the DOJ probe is NVIDIA’s recent acquisition of RunAI, a company that makes software for managing AI computing tasks. The concern is that this purchase will make it harder for business customers to switch away from NVIDIA chips, as it would also necessitate a change in software.

However, that’s not the only reason behind this investigation. Regulators are also looking into whether NVIDIA gives preferential treatment to customers who exclusively use its technology or buy its complete systems. This special treatment allegedly includes first dibs on hardware and related supplies and unique pricing models.

NVIDIA has offered a terse response, telling Bloomberg that it “wins on merit, as reflected in our benchmark results and value to customers, who can choose whatever solution is best for them.” The inference here is that the company’s market dominance comes down to hard work and not sweetheart deals. 

The investigation is still in its early days, as it hasn’t yet blossomed into a formal complaint. The company’s stock took a hit ahead of the DOJ announcement, but that was likely due to continuing delays for its Blackwell AI chip. However, the stock is still up more than double this year as the AI boom continues to do its thing.

Lyft is rolling out a new price lock feature that caps the cost of rides, in an attempt to solve the problem of cost unpredictability for those who rely on the platform for daily commutes. The company says this tool will even work during peak hours, when rides are usually at their most expensive. There are, however, some caveats.

First of all, there’s a required monthly subscription price to use this service, though it’s only $3 per month. There’s also a curious lack of details regarding how exactly the cap works. Does it just average past rides and exclude peak pricing? Is there a limit to just how much can be capped? We reached out to Lyft and will update this post if we hear anything.

One thing is certain. Lyft is planning on this feature being a hit. It has suggested that commuters will take 40 percent more rides once the price lock tool becomes commonplace. However, it's worth noting that Lyft is the one that sets the prices in the first place, so it caused the instability that this tool sets out to solve. 

There’s also a promotion to advertise the price lock mechanism: 100 customers who are starting new jobs will receive free “first day” rides. This will be handled via LinkedIn. Just 100 rides? That seems pretty stingy for a company as large as Lyft, but what do I know?

This isn’t the first time Lyft has tried its hand at a subscription-based service. The company’s Pink subscription service has been an on-again/off-again thing for years. This is more or less a bundle of add-ons at this point. Pink stopped offering ride discounts but began offering perks like free priority pickups and three free cancellations per month. This program is still live, at $10 per month or $100 per year.
