Nvidia became the most valuable company in the world with a market cap of $3.33 trillion, overtaking Microsoft.

The US-based chip manufacturer has control over about 80% of the market for artificial intelligence chips.

“It’s Nvidia’s market; we’re all just trading in it,” a market strategist at a global brokerage firm said. Another analyst called Nvidia’s chips “the new gold or oil in the tech sector.”

Nvidia’s startling ascent in the stock market reached another milestone Tuesday as the chipmaker rose to become the most valuable company in the S&P 500. Investors now say the company is worth over $3.3 trillion.

Nvidia has seen soaring demand for its semiconductors, which are used to power artificial intelligence applications. Revenue more than tripled in the latest quarter from the same period a year earlier.

The company’s journey to be one of the most prominent players in AI has produced some eye-popping numbers. Here’s a look:

The S&P 500 and Nasdaq posted record closing highs for a third straight day on Wednesday after inflation data came in softer than expected but the indexes ended off the day's highs as the Federal Reserve projected only one interest rate cut this year.

The Fed's March projections included three quarter-percentage-point reductions. The U.S. central bank, in a statement at the end of its June 11-12 meeting, also said it left its policy rate unchanged, as expected.

While the demand for weight loss drugs continues to surge, one Wall Street firm is betting that Americans' love for doughnuts is too strong to give them up. 

Truist Securities on Monday upgraded Krispy Kreme to buy from hold, with analysts led by Bill Chappell saying that the negative impact of the glucagon-like peptide 1 (GLP-1) drugs has already been reflected in the stock's current valuation.

The influential investor’s widely anticipated live stream started 25 minutes late, with pounding drums and pictures of cats.

Suddenly the music gave way to a high-pitched drone as Keith Gill, the stock trader known as “Roaring Kitty,” appeared on camera. Wearing sunglasses and bandages — he never explained why, other than to say they were just for show — he cracked open a beer and spoke to hundreds of thousands of viewers who tuned in for investing advice — and instead got a rambling soliloquy that was light on financials.

Nvidia, Wall Street’s favorite artificial intelligence darling, is continuing to swell to staggering heights.

The AI chipmaker’s market capitalization rose to $3.019 trillion on Wednesday, nudging slightly past Apple’s also $2.99 trillion market cap and making it the second-largest publicly traded company in the US by that measure, just behind Microsoft’s market cap of $3.15 trillion.

Nvidia is now the third company in the US, behind Apple and Microsoft, to cross that $3 trillion mark.

A group backed by Wall Street heavyweights BlackRock BLK 0.15%increase; green up pointing triangle and Citadel Securities is planning to start a new national stock exchange in Texas, aiming to take on what they see as onerous regulation at the New York Stock Exchange and Nasdaq. 

When Trillium offered to buy Getty Images for $4 billion in April 2023, the Boston-based investment firm wouldn't disclose how it planned to finance the deal or how much money it managed.

That's because Trillium didn't plan to actually buy Getty, and its brokerage account had a balance of just $17.32.

The latest: The SEC and DOJ on Friday both charged Trillium and its CEO Scott Murray with securities fraud, essentially claiming that the Getty episode was a pump-and-dump scheme.

Normal trading resumed late Monday morning after the New York Stock Exchange said a technical issue had led to large fluctuations in the prices displayed for certain stocks, including Warren Buffett's Berkshire Hathaway.

A little after 11 a.m. ET, the NYSE said the issue involved the market's main electronic stock price publisher, but that most stocks had since reopened or were in the process of reopening.

The New York Stock Exchange on Monday morning said it resolved a technical problem that resulted in the halt of trading in stocks of several high-profile companies, including Class A shares of Warren Buffett’s Berkshire Hathaway Inc.

The shares resumed trading before midday Monday after a lengthy trading halt that appeared to show them changing hands for as low as $185.10, a drop of 99.97%. Experts said any trades actually executed at that level would almost certainly be invalidated.
