OpenAI releases Chrome competitor browser “ChatGPT Atlas,” sending Google shares down

ChatGPT currently poses little threat to Google’s search business, but an OpenAI browser — and the data that comes with it — could change everything.

OpenAI took aim at Google today with its own AI-powered web browser called “ChatGPT Atlas.” The new browser, which is currently only available for Macs, aims to merge ChatGPT with a modern web browser.

An OpenAI team member on the livestream called it “a new kind of browser for the next era of the web.” The newly-unveiled browser could help OpenAI further insert itself into users’ interactions with their computers, and prompt users to more extensively incorporate OpenAI tools in their daily lives.

The initial screen the user sees in the new browser looks a lot like ChatGPT, with a text box in the center. But instead of just entering in the name of a website or search query, users can ask the browser questions. This may take you directly to a website, but it also might search through your tabs and browser history, or pull information together from around the web to deliver a response. Atlas is built on Chromium, the open source version of Google’s Chrome browser.

Google’s AI overviews aim to do a similar thing in response to a search query, but Atlas can deliver answers without pages of search results. Google’s Chrome browser has been key to its domination of online advertising, generating $54.2 billion last quarter alone. Even a small slice of that market would help OpenAI offset the massive losses it is incurring as it ramps up its ambitious infrastructure plans.

One of the key features in Atlas is a persistent “Ask ChatGPT” button which grants the chatbot access to the contents of the webpage being viewed, letting the user ask questions about what is on the page. However, when I tried to ask Atlas questions about the front page of the New York Times, a message popped up that said “ChatGPT is unable to access the contents of this website,” likely due to the ongoing lawsuit between OpenAI and the newspaper.

That’s a reminder that the contents of your journey around the web can be used to train future models. Atlas does give users the ability to opt out, but the setting is turned on by default (but not for Business or Enterprise subscribers). Users can also open an “incognito mode” tab that will not remember what you search for, or what sites you visit.

Atlas has a deep memory — not only does it remember your searches and what sites you visit — your ChatGPT history is available to Atlas as well to help customize responses (this can also be disabled).

Listed as a “preview” feature, Atlas also has a built-in “Agent mode” that will control the web browser to complete tasks on its own. In the livestream, a demo showed Atlas visiting a supermarket website, and adding items to an order based on a recipe. The task took about 2 minutes to fill the cart.

Shares of Google took a nosedive before the announcement on Tuesday, dropping as much as 4%. After the livestream announcing Atlas, shares recovered slightly, but the stock was still down about 1.7%.

Rivian sure picked a bad time for its AI Day as investors dump tech stocks

The event coordination team at Rivian is probably having a bad one, as investors dumped the stock ahead of its “Autonomy and AI Day” amid a broader AI trade sell-off.

Heading into the event that began at noon ET, Rivian shares were down 5%, following a strongly negative reaction to Oracle’s earnings results. The stock began climbing as Rivian’s event started, but remains in the red on the day.

A year flush with tariffs and the end of the EV tax credit has pushed Rivian to pitch a techier version of its future. During Thursday’s event, Rivian said its forthcoming vehicles would ditch Nvidia chips for its own AI chips produced by Taiwan Semiconductor.

The vehicles will feature lidar sensors, enabling “level 4” autonomous driving (similar to Google’s Waymo), the company said. According to CEO RJ Scaringe, the updates will allow Rivian to “pursue opportunities in the rideshare space,” hinting at future robotaxi plans, which rivals Tesla and Lucid have already begun.

Wall Street appears skeptical of Rivian, with Morgan Stanley this week downgrading the stock to “underweight” and dropping its price target to $12. Lucid, which in October announced it’s planning a privately owned autonomous car built with Nvidia tech, also received a downgrade.

Robinhood tumbles after November trading volumes post monthly drop across equities, options, and crypto

Robinhood Markets is getting crushed today, and not just because it’s the place where people go to buy AI stocks (which are under big pressure after Oracle’s earnings report). As stocks retreated in November, activity on the platform did, too.

(Robinhood Markets Inc. is the parent company of Sherwood Media, an independently operated media company subject to certain legal and regulatory restrictions.)

The brokerage reported that November trading volumes fell across equities, options, and crypto compared to October. Equity notional volumes were down 37% month on month, options contracts traded were off 28%, and crypto notional volumes fell double digits. The bright spot: its prediction markets business is still in boom mode, with 3 billion contracts traded, up 20% versus the prior month.

Cantor Fitzgerald analyst Brett Knoblauch trimmed his price target on the shares to $152 from $155 following this release, noting that this monthly decline was somewhat expected.

Oracle’s underwhelming results are kneecapping the AI trade

The nasty reception to Oracle’s quarterly results, which included a small revenue miss along with much more capex and cash burn than analysts had anticipated, is cascading through the rest of the AI trade.

Among the names getting hit hard:

AI chip behemoths Nvidia, Broadcom, and Advanced Micro Devices.
Neoclouds CoreWeave, Nebius, IREN, and Cipher Mining.
Infrastructure providers GE Vernova and Vertiv Holdings.
Server companies Super Micro Computer, Dell, and HP Enterprise.

While stocks have recovered strongly since their November 20 intermediate low, that’s been more about bullishness on Google and its partners as well as global growth than the AI trade broadly.

Only one member of the VanEck Semiconductor ETF is negative during this time: Nvidia. The second-worst performer of the bunch over this stretch is AMD, another AI GPU provider.

PetMed soars after disclosing $4-per-share buyout offer from investment firm

PetMed Express soared after disclosing that it had received a take-private buyout offer from Singapore investment firm SilverCape Investments, valuing the company at a significant premium.

SilverCape would pay $4 per share, a 125% premium from the $1.77 the stock closed at on Wednesday. Shares soared 50% in early trading to $2.65.

PetMed said its board would evaluate the offer.

The company, which has been public sine 1997, has reported stagnating sales and slipped into unprofitability in 2024. The online pet pharmacy is down 60% this year and down 96% since its peak in 2018.
