OpenAI introduced its own web browser, Atlas, on Tuesday, putting the ChatGPT maker in direct competition with Google as more internet users rely on artificial intelligence to answer their questions.
Making its popular AI chatbot a gateway to online searches could allow OpenAI, the world's most valuable startup, to pull in more internet traffic and the revenue made from digital advertising. It could also further cut off the lifeblood of online publishers if ChatGPT so effectively feeds people summarized information that they stop exploring the internet and clicking on traditional web links.
OpenAI has said ChatGPT already has more than 800 million users but many of them get it for free. The San Francisco-based company also sells paid subscriptions but is losing more money than it makes and has been looking for ways to turn a profit.
OpenAI said Atlas launches Tuesday on Apple laptops and will later come to Microsoft’s Windows, Apple’s iOS phone operating system and Google’s Android phone system.
OpenAI CEO Sam Altman called it a “rare, once-a-decade opportunity to rethink what a browser can be about and how to use one.”
But analyst Paddy Harrington of market research group Forrester said it will be a big challenge “competing with a giant who has ridiculous market share.”
OpenAI’s browser is coming out just a few months after one of its executives testified that the company would be interested in buying Google’s industry-leading Chrome browser if a federal judge had required it to be sold to prevent the abuses that resulted in Google’s ubiquitous search engine being declared an illegal monopoly.
But U.S. District Judge Amit Mehta last month issued a decision that rejected the Chrome sale sought by the U.S. Justice Department in the monopoly case, partly because he believed advances in the AI industry already are reshaping the competitive landscape.
OpenAI’s browser will face a daunting challenge against Chrome, which has amassed about 3 billion worldwide users and has been adding some AI features from Google’s Gemini technology.
Chrome’s immense success could provide a blueprint for OpenAI as it enters the browser market. When Google released Chrome in 2008, Microsoft’s Internet Explorer was so dominant that few observers believed a new browser could mount a formidable threat.
But Chrome quickly won over legions of admirers by loading webpages more quickly than Internet Explorer while offering other advantages that enabled it to upend the market. Microsoft ended up abandoning Explorer and introducing its Edge browser, which operates similarly to Chrome and holds a distant third place in market share behind Apple's Safari.
Perplexity, another smaller AI startup, rolled out its own Comet browser earlier this year. It also expressed interest in buying Chrome and eventually submitted an unsolicited $34.5 billion offer for the browser that hit a dead end when Mehta decided against a Google breakup.
Altman said he expects a chatbot interface to replace a traditional browser’s URL bar as the center of how he hopes people will use the internet in the future.
“Tabs were great, but we haven’t seen a lot of browser innovation since then,” he said on a video presentation aired Tuesday.
A premium feature of the ChatGPT Atlas browser is an “agent mode” that accesses the laptop and effectively clicks around the internet on the person’s behalf, armed with a users’ browser history and what they are seeking to learn and explaining its process as it searches.
“It’s using the internet for you,” Altman said.
Harrington, the Forrester analyst, says another way of thinking about that is it's “taking personality away from you.”
“Your profile will be personally attuned to you based on all the information sucked up about you. OK, scary,” Harrington said. “But is it really you, really what you're thinking, or what that engine decides it's going to do? ... And will it add in preferred solutions based on ads?”
About 60% of Americans overall — and 74% of those under 30 — use AI to find information at least some of the time, making online searches one of the most popular uses of AI technology, according to findings from an Associated Press-NORC Center for Public Affairs Research poll taken over the summer.
Google since last year has automatically provided AI-generated responses that attempt to answer a person’s search query, appearing at the top of results.
Reliance on AI chatbots to summarize information they collect online has raised a number of concerns, including the technology's propensity to confidently spout false information, a problem known as hallucination.
The way that chatbots trained on online content spout new writings has been particularly troubling to the news industry, leading The New York Times and other outlets to sue OpenAI for copyright infringement and others, including The Associated Press, to sign licensing deals.
A study of four top AI assistants including ChatGPT and Google’s Gemini released Wednesday showed nearly half their responses were flawed and fell short of the standards of “high-quality” journalism.
The research from the European Broadcasting Union, a group of public broadcasters in 56 countries, compiled the results of more than 3,000 responses to news-related questions to help ascertain quality responses and identify problems to fix.

NEW YORK (AP) — Stocks are rushing higher worldwide, and oil prices are easing Wednesday as hopes build that the war with Iran could end soon. That's even though some of the signals investors saw as hopeful are already under dispute, and several prior bouts of optimism in financial markets quickly got undercut by continued, fierce fighting in the war.
The S&P 500 rose 0.8% and added to its leap from the day before, which was its best since last spring. That followed even bigger gains for stock markets across Europe and Asia, including an 8.4% surge in South Korea, which were catching up to Wall Street’s rally from Tuesday.
The Dow Jones Industrial Average was up 357 points, or 0.8%, as of 10:45 a.m. Eastern time, and the Nasdaq composite was 1.2% higher.
Oil prices also fell back toward $100 per barrel after President Donald Trump claimed shortly before Wall Street began trading that Iran “has just asked the United States of America for a CEASEFIRE!”
“We will consider when Hormuz Strait is open, free, and clear. Until then, we are blasting Iran into oblivion or, as they say, back to the Stone Ages!!!”
Trump had also said the night before that the U.S. military could end its offensive in two to three weeks. That added to optimism following a couple tenuous signals of hope from earlier Tuesday that Wall Street latched onto, including a news report quoting Iran’s president as saying that it has “the necessary will to end the war” as long as certain requirements are met, including “guarantees to prevent a recurrence of aggression.”
The worry on Wall Street has been that the war may last a long time and keep oil and natural gas from the Persian Gulf out of global markets, which could create a brutal blast of inflation.
But hope has been quick to reverse to doubt on Wall Street, triggering manic swings back and forth for financial markets since the war with Iran began. Trump has also made statements that lifted markets, only to see the gains quickly disappear after increasing his military threats against Iran. Investors say Trump’s statements are becoming less impactful for financial markets.
Iran’s Foreign Ministry spokesman, Esmail Baghaei, called Trump’s claim about asking for a ceasefire “false and baseless,” according to a report on Iranian state television.
And oil prices remain high, even if they’ve eased so far this week. The price for a barrel of Brent crude oil, the international standard, was sitting at $101.83 following its declines, which is still up from roughly $70 before the war began.
U.S. gasoline prices rose again overnight to a national average of $4.06 per gallon, according to the auto club AAA.
Iran, meanwhile, hit an oil tanker off the coast of Qatar and Kuwait’s airport on Wednesday while airstrikes battered Tehran as the fighting continued. Iran also continues to hold a grip on the Strait of Hormuz, where a fifth of the world’s traded oil passes during peacetime.
“De-escalation hopes have given markets a lift, but we think the effects of the war would, in many cases, persist even if the war did end soon,” Thomas Mathews, head of markets, Asia Pacific at Capital Economics, said in a research note Wednesday.
“It’s worth thinking through how markets might fare if the war were to end ‘very soon,’” he wrote. “Do markets have further to recover if sentiment continues to improve? The answer is almost certainly yes.”
The White House said Trump will deliver a public address Wednesday evening on the Iran war.
On Wall Street, the majority of stocks rose, with Big Tech powering the move higher. Gains of 2.5% for Alphabet and 1% for Nvidia were two of the strongest forces lifting the S&P 500.
They helped offset a 14.3% drop for Nike, which fell even though it reported a stronger profit for the latest quarter than expected. Analysts said it gave some lackluster financial forecasts.
Hasbro fell 3.8% after the toy company found someone had gained unauthorized access to its computer network and is working to assess the full impact.
In stock markets abroad, indexes leaped more than 1.5% in France, Germany and the United Kingdom. Asian markets had even bigger gains.
Tokyo’s Nikkei 225 jumped 5.2% after a survey by Japan’s central bank showed business sentiment for major Japanese manufacturers improved despite worries about the Iran war.
In the bond market, Treasury yields held relatively steady after a report said U.S. retailers made more money in February than economists expected. A separate report said U.S. manufacturing growth last month was slightly faster than economists expected.
The 10-year Treasury yield rose to 4.31% from 4.30% late Tuesday.
