There is concern that subscribers might be negatively affected if Netflix acquires Warner Bros. Discovery’s streaming and movie studios businesses. One of the biggest fears is that the merger would lead to higher prices due to less competition for Netflix.

During a US Senate hearing Tuesday, Netflix co-CEO Ted Sarandos suggested that the merger would have an opposite effect.

Sarandos was speaking at a hearing held by the US Senate Judiciary Committee’s Subcommittee on Antitrust, Competition Policy, and Consumer Rights, “Examining the Competitive Impact of the Proposed Netflix-Warner Brothers Transaction.”

Sarandos aimed to convince the subcommittee that Netflix wouldn’t become a monopoly in streaming or in movie and TV production if regulators allowed its acquisition to close. Netflix is the largest subscription video-on-demand provider by subscribers (301.63 million as of January 2025), and Warner Bros. Discovery is the third (128 million streaming subscribers, including users of HBO Max and, to a smaller degree, Discovery+).

Speaking at the hearing, Sarandos said: “Netflix and Warner Bros. both have streaming services, but they are very complementary. In fact, 80 percent of HBO Max subscribers also subscribe to Netflix. We will give consumers more content for less.”

During the hearing, Democratic senator Amy Klobuchar of Minnesota asked Sarandos how Netflix can ensure that streaming remains “affordable” after a merger, especially after Netflix issued a price hike in January 2025 despite adding more subscribers.

Sarandos said the streaming industry is still competitive. The executive claimed that previous Netflix price hikes have come with “a lot more value” for subscribers.

“We are a one-click cancel, so if the consumer says, ‘That’s too much for what I’m getting,’ they can cancel with one click,” Sarandos said.

When pressed further on pricing, the executive argued that the merger doesn’t pose “any concentration risk” and that Netflix is working with the US Department of Justice on potential guardrails against more price hikes.

Sarandos claimed that the merger would “create more value for consumers.” However, his idea of value isn’t just about how much subscribers pay to stream but about content quality. By his calculations, which he provided without further details, Netflix subscribers spend an average of 35 cents per hour of content watched, compared to 90 cents for Paramount+.

The Netflix stat is similar to one provided by MoffettNathanson in January 2025, finding that in the prior quarter, on average, Netflix generated 34 cents in subscription fees per hour of content viewed per subscriber. At the time, the research firm said Paramount+ made an average of 76 cents per hour of content viewed per subscriber.

Downplaying Monopoly Concerns

Netflix views Warner as “both a competitor and a supplier,” Sarandos said when subcommittee chair Republican senator Mike Lee of Utah asked why Netflix wants to buy WB’s film studios, per Variety. The streaming executive claimed that Netflix’s “history is about adding more and more” content and choice.

During the hearing, Sarandos argued that streaming is a competitive business and pointed to Google, Apple, and Amazon as “deep-pocketed tech companies trying to run away with the TV business.” He tried to downplay concerns that Netflix could become a monopoly by emphasizing YouTube’s high TV viewership. Nielsen’s The Gauge tracker shows which platforms Americans use most when using their TVs (as opposed to laptops, tablets, or other devices). In December, it said that YouTube, not including YouTube TV, had more TV viewership (12.7 percent) than any other streaming video-on-demand service, including second-place Netflix (9 percent). Sarandos claimed that Netflix would have 21 percent of the streaming market if it merged with HBO Max.

Some children affected by measles in the ongoing South Carolina outbreak have developed a serious complication of the disease called encephalitis, or swelling of the brain, state epidemiologist Linda Bell said on Wednesday.

The South Carolina measles outbreak began in October with a handful of infections. As of February 3, cases have climbed to 876, with 700 of those being reported since the beginning of the year. The surge could mean another bad year of measles for the United States, which had more than 2,267 cases—the highest in 30 years—in 2025. Declining vaccination rates across the country are driving the resurgence.

Encephalitis is a rare but severe complication of measles that can lead to convulsions and cause deafness or intellectual disability in children. It usually occurs within 30 days of an initial measles infection and can happen if the brain becomes infected with the virus or if an immune reaction to the virus causes inflammation in the brain. Among children who get measles encephalitis, 10 to 15 percent die.

It’s not known how many children in South Carolina have developed this serious complication. Under state law, measles cases must be reported to the South Carolina Department of Public Health, but measles hospitalizations and complications do not need to be disclosed.

“We don’t comment on the outcomes of individuals, but we do know that inflammation of the brain, or encephalitis, is a known complication of measles,” Bell told reporters during a media briefing on Wednesday. “Anytime you have inflammation of the brain, there can be long-term consequences, things like developmental delay and impacts on the neurologic system that can be irreversible.”

The department is aware of 19 measles-related hospitalizations in the state, including some due to pneumonia, which occurs in about one in 20 children with measles and is the leading cause of death for children who get measles.

Bell also said that several pregnant women who were exposed to the virus required administration of immune globulin, a concentrated solution of antibodies. It provides temporary protection against measles for unvaccinated individuals. Measles exposure during pregnancy can cause preterm birth or miscarriage.

A rarer type of brain swelling called subacute sclerosing panencephalitis, or SSPE, can occur years after a measles infection. In September, the Los Angeles County Department of Public Health reported the death of a school-age child due to SSPE. The child was originally infected with measles as an infant before they were old enough to receive the measles vaccine, the first dose of which is recommended for children between 12 and 15 months old.

After recovering from the initial measles illness, the child developed SSPE, in which the virus remains dormant in the brain before triggering an inflammatory response that destroys brain tissue over time. The condition usually appears seven to 10 years after a person appears to recover from the initial measles infection. An estimated two in 10,000 people who get measles eventually develop SSPE.

The measles, mumps, and rubella (MMR) vaccine is the best way to prevent measles and serious complications associated with it.

Over 7,000 more doses of the MMR vaccine were given statewide in South Carolina this January compared to January 2025, a 72 percent increase. In Spartanburg County, the center of the outbreak, over 1,000 more doses were given this January compared to January 2025, a 162 percent increase. So far, January was the best month for measles vaccination during the outbreak, Bell said.

Five years ago, mathematicians Dawei Chen and Quentin Gendron were trying to untangle a difficult area of algebraic geometry involving differentials, elements of calculus used to measure distance along curved surfaces. While working on one theorem, they ran into an unexpected roadblock: Their argument depended on a strange formula from number theory, but they were unable to solve or justify it. In the end, Chen and Gendron wrote a paper presenting their idea as a conjecture, rather than a theorem.

Chen recently spent hours prompting ChatGPT in the hopes of getting the AI to come up with a solution to the still unsolved problem, but it wasn’t working. Then, during a reception at a math conference in Washington, DC, last month, Chen ran into Ken Ono, a well-known mathematician who had recently left his job at the University of Virginia to join Axiom, an artificial intelligence startup cofounded by one of his mentees, Carina Hong.

Chen told Ono about the problem, and the following morning, Ono presented him with a proof, courtesy of his startup’s math-solving AI, AxiomProver. “Everything fell into place naturally after that,” says Chen, who worked with Axiom to write up the proof, which has now been posted to arXiv, a public repository for academic papers.

Axiom’s AI tool found a connection between the problem and a numerical phenomenon first studied in the 19th century. It then devised a proof, which it helpfully verified itself. “What AxiomProver found was something that all the humans had missed,” Ono tells WIRED.

The proof is one of several solutions to unsolved math problems that Axiom says its system has come up with in recent weeks. The AI has not yet solved any of the most famous (or lucrative) problems in the field of mathematics, but it has found answers to questions that have stumped experts in different areas for years. The proofs are evidence of AI’s steadily advancing math abilities. In recent months, other mathematicians have reported using AI tools to explore new ideas and solve existing problems.

The techniques being developed by Axiom may prove useful outside the world of advanced math. For example, the same approaches could be used to develop software that is more resilient to certain kinds of cybersecurity attacks. This would involve using AI to verify that code is provably reliable and trustworthy.

“Math is really the great test ground and sandbox for reality,” says Hong, Axiom’s CEO. “We do believe that there are a lot of pretty important use cases of high commercial value.”

Axiom’s approach involves combining large language models with a proprietary AI system called AxiomProver that is trained to reason through math problems to reach solutions that are provably correct. In 2024, Google demonstrated a similar idea with a system called AlphaProof. Hong says that AxiomSolver incorporates several significant advances and newer techniques.

Ono says the AI-generated proof for the Chen-Gendron conjecture shows how AI can now meaningfully assist professional mathematicians. “This is a new paradigm for proving theorems,” he says.

Axiom’s system is more than just a regular AI model, in that it is able to verify proofs using a specialized mathematical language called Lean. Rather than just search through the literature, this allows AxiomProver to develop genuinely novel ways of solving problems.

Another one of the new proofs generated by AxiomProver demonstrates how the AI is capable of solving math problems entirely on its own. That proof, which has also been described in a paper posted to arXiv, provides a solution to Fel’s Conjecture, which concerns syzygies, or mathematical expressions where numbers line up in algebra. Remarkably, the conjecture involves formulas first found in the notebook of legendary Indian mathematician Srinivasa Ramanujan more than 100 years ago. In this case AxiomProver did not just fill in a missing piece of the puzzle, it devised the proof from start to finish.
