As thousands of homes started to burn across Los Angeles on Jan. 7, fire hydrants stopped working. The rapid spread of flames in winds up to 100 miles per hour was happening too quickly for water pumps to keep up. It shocked the system and those fleeing the flames.

“This area is known for having fire issues, so you would think that they would be prepared for this,” said Joan Zoloth, 70, who said she first moved to the area when she was 6 years old.

Zoloth’s childhood home burned down in the Palisades Fire. Her own home around the corner and her son’s home nearby were also lost. 

“My mother was a teacher,” Zoloth said. “What people don’t realize is how much Malibu is filled with those types of people — not just movie stars.”

CNBC went to the wreckage of the Palisades Fire to ask officials what happened to the water system in LA, and what other cities can do to be better prepared. As many as 1 in 6 Americans now live in areas with significant wildfire risk. 

“A firefight at this size, such an urban conflagration, any system is going to have its challenges in maintaining water pressure,” said State Fire Marshall Daniel Berlant, of the California Department of Forestry and Fire Protection, known as Cal Fire.

Water pressure was the primary problem, rather than a lack of supply, fire officials and water experts told CNBC. 

Much of the water in the Palisades is provided by three 1 million gallon tanks that sit up in the hills, using gravity to maintain water pressure in the hydrants and homes they supply below.

Pumps forcibly move water from main lines and surrounding reservoirs to those tanks. The tanks were full when the fires started, but the pumps couldn’t replenish water in the tanks as quickly as firefighters were using it below. As the tanks depleted, so did the water pressure, until some 20% of hydrants ran dry.

“The hydrants would have run dry anywhere in the world with a fire event like this in the topography where this occurred,” said Greg Pierce, director of the UCLA Human Right to Water Lab.

Joan Zoloth lost three family homes in Malibu during the Palisades fire. She’s shown here at a family friend’s house where she’s staying in Venice, California, on January 21, 2025.

The closure of a 117 million gallon reservoir nearby complicated matters. Earlier this month, California Gov. Gavin Newsom and LA city council members called for investigations into why the Santa Ynez Reservoir hadn’t yet reopened after being drained almost a year ago to repair a tear in its cover.

“That would have made a difference,” Pierce said. “But even, by all accounts, if that reservoir was full, it wouldn’t have stopped the fire.”

Typically, fires are also fought by aircraft dropping water and fire retardant from above, but high winds kept them grounded for several hours on the first night of the fire.

Firefighters adapted with three tactics. They shuttled water through multiple engines connected to functional hydrants, drove it to locations in large water tenders, and pumped water directly from backyard swimming pools.

The LA Department of Water and Power said it quadrupled the water flow to the area and summoned 15 water tankers to directly refill fire trucks. It wasn’t enough.

The blame game

As immediate danger calmed, misinformation ran wild. The Federal Emergency Management Agency, or FEMA, reactivated its rumor response site, and the LA Fire Department directly responded to inaccurate social media posts.

President Donald Trump, for instance, claimed that water ran out in LA because of policies meant to protect a small endangered fish called the Delta smelt.

“It’s just simply false. It’s nonsense,” said Peter Gleick, co-founder of the Pacific Institute, a global water think tank. Gleick has been researching water issues for four decades.

On his first day back in office, Trump signed an executive order titled “Putting People Over Fish: Stopping Radical Environmentalism to Provide Water to Southern California.” After visiting with Newsom in LA, Trump signed another executive order directing federal officials to find ways to override “disastrous” California water policies. 

“There’s lots of conversations about California water policy and how we allocate water to protect fish or ecosystems versus deliver water to different kinds of users, but that had no role whatsoever to play in water availability for firefighting,” Gleick said.

Southern California reservoirs are at above-average levels for this time of year because of two plentiful rainy seasons, he added.

“Misinformation about how if we just had more water from Northern California in Southern California, that would have made the difference, that’s not true,” UCLA’s Pierce said. “Even if you have water stored fairly close by in the region, you can’t just move it quickly up to an area like the Palisades.”

That’s why billionaires Lynda and Stewart Resnick are also not to blame for the Palisades Fire, the water experts who spoke with CNBC said. 

The Resnicks own the Wonderful Company, which includes brands such as Pom and Fiji Water, and have sprawling farmlands in the San Joaquin Valley that grow pistachios, oranges and pomegranates. They’ve been the subject of attacks on social media, some of which are antisemitic, that blame them for the water pressure problems in LA because of their investment in a public-private water bank that’s 100 miles north of LA and that has no ability to impact water pressure in the Palisades.

“There’s absolutely no connection between the two. This is a localized problem,” said Felicia Marcus, former chair of the California State Water Resources Control Board.

The fires also resurfaced criticism around state and local water decisions, from taking down dams to not building enough reservoirs.

The real culprit is extremely dry conditions, experts told CNBC. Before the fires, LA saw close to zero rain since May, and 2024 was the hottest year on record for the planet, Gleick said.

“Higher temperatures means more demand for water by soils and vegetation and people and agriculture,” he said. “Climate change is in many ways a water problem. It’s being manifested by drought and floods and wildfires.”

More resilient water systems

This is not the first time hydrants ran dry in a major firefight. They’re designed to handle one or two structure fires, not hundreds burning at the same time.

Similar water pressure problems plagued the 1991 Oakland Hills Fire, which destroyed more than 3,000 homes, and two Ventura County fires that each burned more than 1,000 homes in 2017 and 2018

The problem extends beyond California. Texas saw the largest fire in its history last February. As population booms, more people are moving to areas at high risk of fires between dense developments and wildland. 

California is home to the top six cities at highest wildfire risk in the U.S., but Texas, Colorado and Oregon also have cities in the top 15.

A firefighting helicopter draws water from the first-ever installed Heli-Hydrant to quickly stop the Blue Ridge Fire in Yorba Linda, California, on October 28, 2020.

Yorba Linda Water District

There are three key components to making water systems more resilient, Pierce said: increasing water supply, improving local infrastructure, and bolstering power.

After a 2008 fire that destroyed 280 homes, Yorba Linda Water District in California addressed all three. It added backup generators at water pump stations that had failed during the fire, added a long-planned underground reservoir, and installed a first-of-its-kind water tank called a Heli-Hydrant.

That $70,000 tank can automatically refill itself and is reserved for helicopters to dip from, reducing the length of flight times between water pickups and drops. It was used to quickly stop the Blue Ridge Fire in 2020.

“Cal Fire was able to jump on it and use our Heli-Hydrant, trigger it and keep the fire to five acres,” said John DeCriscio, who was operations manager at the Yorba Linda Water District at the time. “That was a huge success.”

San Francisco implemented a comprehensive solution after the city was almost completely destroyed in the 1906 earthquake and resulting fire, which also caused most hydrants to run dry. 

In 1913, the city developed a unique fire-suppression water system separate from the rest of the city’s water. Seawater enters the system from 52 suction connections along the waterfront, and it’s pumped in from fireboats and two high-pressure pumping stations. There are more than 200 underground cisterns to store backup water. A high-elevation reservoir and two large-capacity tanks use gravity, not pumps, to feed special high-pressure emergency hydrants that can be seen around the city with black, red and blue tops.

There are other solutions that cities can implement.

A company called Rain is working on autonomous, unmanned aircraft for dropping water on fires. In Japan, an autonomous system of water cannons protects a cultural heritage site with 200-year-old thatched roof houses.

Cost is the main reason these solutions haven’t been implemented widely. 

“There’s always this delicate balance of being afraid to go to your customers and raise their rates, but if you don’t raise their rates, you can’t do these extra things,” said Marcus, the former state water board chair. “It’s the kind of thing that keeps you up at night when you manage one of these agencies.”

Apple’s China iPhone sales grows for the first time in two years

Apple's China iPhone sales grows for the first time in two years

Apple iPhone sales in China rose in the second quarter of the year for the first time in two years, Counterpoint Research said, as the tech giant looks to turnaround its business in one of its most critical markets.

Sales of iPhones in China jumped 8% year-on-year in the three months to the end of June, according to Counterpoint Research. It’s the first time Apple has recorded growth in China since the second quarter of 2023.

Apple’s performance was boosted by promotions in May as Chinese e-commerce firms discounted Apple’s iPhone 16 models, its latest devices, Counterpoint said. The tech giant also increased trade-in prices for some iPhone.

“Apple’s adjustment of iPhone prices in May was well timed and well received, coming a week ahead of the 618 shopping festival,” Ethan Qi, associate director at Counterpoint said in a press release. The 618 shopping festival happens in China every June and e-commerce retailers offer heavy discounts.

Apple’s return to growth in China will be welcomed by investors who have seen the company’s stock fall around 15% this year as it faces a number of headwinds.

U.S. President Donald Trump has threatened Apple with tariffs and urged CEO Tim Cook to manufacture iPhones in America, a move experts have said would be near-impossible. China has also been a headache for Apple since Huawei, whose smartphone business was crippled by U.S. sanctions, made a comeback in late 2023 with the release of a new phone containing a more advanced chip that many had thought would be difficult for China to produce.

Since then, Huawei has aggressively launched devices in China and has even begun dipping its toe back into international markets. The Chinese tech giant has found success eating away at some of Apple’s market share in China.

Huawei’s sales rose 12% year-on-year in the second-quarter, according to Counterpoint. The firm was the biggest player in China by market share in the second quarter, followed by Vivo and then Apple in third place.

“Huawei is still riding high on core user loyalty as they replace their old phones for new Huawei releases,” Counterpoint Senior Analyst Ivan Lam said.

Like Google, China's biggest search player Baidu is beefing up its product with AI to fight rivals

Chinese tech giant Baidu has bolstered its core search platform with artificial intelligence in the biggest overhaul of the product in 10 years.

Analysts told CNBC the move was a bid to keep ahead of fast-moving rivals like DeepSeek, rather than traditional search players.

“There has been some small pressure on the search business but the focus on AI and Ernie Bot is a key move ahead,” Dan Ives, global head of tech research at Wedbush Securities, told CNBC by email. Ernie Bot is Baidu’s AI chatbot.

“Baidu is not waiting around to watch the paint dry, full steam ahead on AI,” he added.

Baidu AI overhaul

Baidu is China’s biggest search engine, but — as is also being seen by Google — the search market is being disrupted.

Users are flocking instead to AI services such as ChatGPT or DeepSeek, which shocked the world this year with its advanced model it claimed was created at a fraction of the cost of rivals.

But Kai Wang, Asia equity market strategist at Morningstar, also noted that short video platforms such as Douyin and Kuaishou are also getting into AI search and piling pressure on Baidu.

To counter this, Baidu made some major changes to its core search product:

  • Users can now enter more than a thousand characters in the search box, versus 28 previously;
  • Questions can be asked in a more direct and conversational manner, mirroring how people now use chatbots;
  • Users can ask questions through voice but also prompt the seach engine with pictures and files;
  • Baidu has integrated its AI chatbot features, which enable users to generate photos, text and videos, into the product.

“This is more aligned with how people use ChatGPT and DeepSeek in terms of how they look for answers,” Wang said.

Outside of China, Google has also been looking to enhance its core search product with AI, highlighting how search has been under pressure from the burgeoning technology.

Baidu on the offense

Baidu was one of China’s first movers when it came to AI, releasing its first models and ChatGPT-style product Ernie Bot to the public in 2023. Since then, it has aggressively launched updated AI models.

However, the Beijing-headquartered company has also faced intense competition from fellow tech giants like Alibaba and Tencent, as well as upstarts such as DeepSeek.

These companies have also been launching new models and infusing AI into their products and Baidu’s stock has fallen behind as a result. Baidu shares have risen around 2.5% this year, versus a 30.5% surge for Alibaba and a 20% rise for Tencent.

“This is a defensive and offensive move … Baidu needs to be aggressive and perception-wise show they are not the little brother to Tencent on the AI front,” Wedbush Securities’ Ives added.

LONDON — ElevenLabs, a London-based startup that specializes in generating synthetic voices through artificial intelligence, has revealed plans to be IPO-ready within five years.

The company told CNBC it is targeting major global expansion as it prepares for an initial public offering.

“We expect to build more hubs in Europe, Asia and South America, and just keep scaling,” Mati Staniszewski, ElevenLabs’ CEO and co-founder, told CNBC in an interview at the firm’s London office.

He identified Paris, Singapore, Brazil and Mexico as potential new locations. London is currently ElevenLabs’ biggest office, followed by New York, Warsaw, San Francisco, Japan, India and Bangalore.

Staniszewski said the eventual aim is to get the company ready for an IPO in the next five years.

“From a commercial standpoint, we would like to be ready for an IPO in that time,” he said. “If the market is right, we would like to create a public company … that’s going to be here for the next generation.”

Fundraising plans

ElevenLabs was valued at $3.3 billion following a recent $180 million funding round. The company is backed by the likes of Andreessen Horowitz, Sequoia Capital and ICONIQ Growth, as well as corporate names like Salesforce and Deutsche Telekom.

Staniszewski said his startup was open to raising more money from VCs, but it would depend on whether it sees a valid business need, like scaling further in other markets. “The way we try to raise is very much like, if there’s a bet we want to take, to accelerate that bet [we will] take the money,” he said.
