Reddit soars after suing Anthropic, alleging it trained AI on personal user data without permission

While other AI companies have played by the rules, Reddit says Anthropic has officially crossed the line.

Reddit shares popped nearly 8% Tuesday afternoon after the social media platform filed a lawsuit against AI startup Anthropic. In the suit, Reddit alleges Anthropic engaged in “unlawful and unfair business acts” by using its data without permission.

Reddit alleges that Anthropic, in particular, has been using personal information from its users to train AI models.

The lawsuit, filed in San Francisco, says that other AI giants have respected the platform’s rules, which is why Reddit has entered formal licensing partnerships with companies like OpenAI and Google. Reddit has become a key player in the generative-AI boom, thanks to its massive archive of user-generated content that’s become prime training material for AI models like Anthropic’s Claude.

“While Reddit has always been of the mind that the community should be open to all humans looking for connection and community, it has never allowed its platform and the countless communities who find a home on it to be appropriated by commercial actors seeking to create billion-dollar enterprises and offering nothing in return to Reddit and its users,” the lawsuit states.

Reddit said it’s seeking damages and aims to compel Anthropic to comply with its contractual and legal obligations. Reddit shares are down about 28% year to date, but have more than doubled over the past year.

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.”
