Nvidia pares gains after Amazon launches newest AI chip

The problem with being the king is that everyone’s trying to get their hands on your shiny crown.

Shares of Nvidia pared gains after Amazon publicly launched its custom chip, called the Trainium3, as part of its AWS re:Invent 2025 event in Las Vegas.

The company said these chips can cut costs associated with training and using AI models by up to 50% compared to GPU-based systems offered by the likes of Nvidia and Advanced Micro Devices.

The potential for increased competition, particularly from Google, which is reportedly in talks to sell its custom TPUs codesigned with Broadcom to Meta, has been a drag on Nvidia shares as of late, as this has the potential to weigh on its market share and profitability.

Nvidia came into the week trading at a record discount to Broadcom, the custom chip specialist, based on 12-month price-to-earnings ratios.

Even as traders fret over competition, however, it’s clear that leading tech companies are building for a future in which Nvidia is still the dominant player. For instance, Amazon said that the next edition of this custom chip (Trainium4) “will support Nvidia NVLink Fusion high-speed chip interconnect technology.”

In other words, Amazon is preparing for a world in which its upcoming chips will be used in tandem with Nvidia’s offerings.

SpaceX gets a wave of bullish ratings from Wall Street analysts

SpaceX received more than a dozen positive analyst calls on Tuesday — including from major Wall Street banks — as they initiate coverage on Elon Musk’s space and AI company.

SpaceX went public on June 12 at a $2.2 trillion valuation, the largest debut in history. While the company hasn’t yet posted a profit, it seems to have convinced Wall Street that it will get there and grow its valuation on the way.

Of the at least 17 analysts that gave a rating on Tuesday, all but one gave it a “buy” or “outperform” rating. MoffettNathanson was "neutral."

The ratings come as SpaceX joined the Nasdaq 100 index, a benchmark tech-heavy basket of companies that underpins millions of portfolios. The inclusion adds built-in demand for the stock from index funds and ETFs.

Still, SpaceX fell more than 5% on Tuesday amid a broader sell-off, and is currently effectively flat from its opening price of $150 a share.

Nike sinks to lowest level since 2014 after warning of “challenged” sales environment in Q4 report

Did Nike do it?

Investors had a mixed reaction after the global sports apparel company reported its fourth quarter earnings on Tuesday after the bell. Shares initially rose 5% as Nike beat out Wall Street expectations amid a hefty tariff refund bonus. However, the stock then sank to its lowest level since August 2014 in postmarket trading.

Here are the Q4 numbers:

  • Revenue of $11.0 billion (estimate: $10.8 billion).

  • Adjusted earnings per share of $0.20 (estimate: $0.12).

Ahead of this report, Nike warned that results would be flattered by a one-time tariff refund (now estimated at roughly $0.52 per share for the bottom line). That gave the company an extra cushion in snapping its streak of seven quarters of year-over-year profit declines.

Over the past year, the company had been punished by tariffs on imported goods, stagnant consumer spending, and increasing competition from other footwear brands like New Balance, Adidas, and Hoka.

Outgoing CFO Matthew Friend deemed it an “increasingly challenging operating environment, where sell-through remains challenged.”
