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.

Figma spikes after raising full-year sales outlook as the software company leverages AI for growth

Figma jumped postmarket Thursday after posting impressive sales in Q1, surpassing Wall Street expectations and raising its full-year guidance. The key numbers:

  • Q1 revenue of $333.4 million (compared to analyst estimates of $316 million).

  • Q2 sales guidance of $348 million to $350 million (estimate: $329.7 million).

  • Full-year revenue between $1.422 billion and $1.428 billion (up from previous guidance of $1.37 billion).

The digital design software firm is the latest company to diminish investor fears about AI-induced disruption by making the technology work for them. Like Atlassian or Datadog, Figma said it was able to use AI to its advantage, bringing more customers on board and getting them to spend more.

In the press release, Praveer Melwani, Figma CFO, said:

As AI gets better, Figma is accelerating and customer usage and workflows on our platform are deepening. Our platform and AI products drove faster growth for both new customer acquisition and expansion within existing accounts.

Revenue grew 46% year over year in Q1 2026, an acceleration from growth of 40% in Q4 2025.

Infleqtion reports Q1 adjusted loss, offers modest boost to full-year sales guidance

Infleqtion is falling in postmarket trading after reporting a Q1 adjusted loss from operations of $13.2 million and sales of $9.5 million.

Management modestly upgraded its sales guidance to “at least” $40 million for 2026, adding that language to enhance the target provided in early April. Revenues of $40 million would mark an increase of roughly 23% compared to the $32.5 million generated in 2025, and an acceleration from growth of 12% last year.

The company utilizes neutral-atom technology to make quantum sensors used in clocks and antennas in addition to computers.

“Q1 reinforced our confidence that quantum is gaining momentum as the market shifts toward deployable systems, real applications, and measurable customer value,” said CEO Matt Kinsella. “Across computing, sensing, and software, we are seeing expanding customer activity especially in national security, space, and hybrid quantum-AI applications.”

Shares are roughly flat since February 13, which is just before the company went public via a SPAC, after being down 35% near the end of March, and then up nearly 30% in mid-April.

The quantum computing space benefited from the return of speculative appetite in April after the US and Iran agreed to a ceasefire. The cohort was later bolstered after Nvidia unveiled a suite of open models designed to leverage AI to improve calibration and error correction for quantum computers.

Applied Materials rallies after better-than-expected Q2 results, strong sales guidance

Shares of Applied Materials are gaining in postmarket trading after the company reported robust Q2 results and a sales outlook that indicate building momentum.

  • Net sales: $7.9 billion (compared to analyst estimates of $7.7 billion and guidance for $7.65 billion, plus or minus $500 million).

  • Adjusted earnings per share: $2.86 (estimate: $2.68, guidance: $2.68, plus or minus $0.20).

For Q3, the company anticipates net sales of $8.95 billion (plus or minus $500 million; estimate: $8.15 billion) with adjusted EPS of $3.36 (plus or minus $0.20; estimate: $2.88).

“The growth in AI that Applied has been investing for is now in full force,” CFO Brice Hill said in the press release.

Management has consistently indicated that it expects demand to pick up in the second half of this year, but its first-half results have already blown away expectations by a wide margin. All this appetite for semiconductors to support AI compute is fantastic news for companies like Applied Materials that make the equipment to produce these specialized chips.

Shares of Applied Materials closed near a record high ahead of this report, up more than 70% year to date.
