The crypto market was under pressure as the new month kicked off, with investors digesting the risks of the latest DeFi hack and the latest opinion from a federal court on when to treat crypto assets as securities.

On Tuesday, bitcoin was lower by 1.1% at $28,867.96, according to Coin Metrics. It ended July down 3.93%.

Ether, which has joined bitcoin in recent months as a sort of large cap, blue-chip trade in crypto, was down by 1.4%, after finishing July down by 3.35%. It was under extra pressure due to a recent exploit in DeFi giant Curve, however.

“Ethereum is sort of the king of DeFi and is viewed as one of the most important liquidity providers in DeFi,” said Josh Gilbert, an analyst at investment firm eToro. “It is a massive project so it’s not going to come under as much pressure as smaller alts but that Curve issue is ultimately the reason we’re seeing weakness in Ethereum right now.”

Altcoins fell after a federal judge said some crypto assets are securities regardless of the context in which they are sold. This opinion contradicted an earlier ruling from the same district court that said Ripple’s XRP may not be categorized as a security in all circumstances.

XRP fell 3%. Tokens named in the recent SEC lawsuits against Binance and Coinbase as potential securities were lower, including those tied to the Solana and Cardano networks, which fell more than 2%. Polygon’s matic token lost 1.75%.

DeFi giant hacked

Other smaller coins, specifically in the DeFi segment of the market, were in the red, too. CRV, the native token of Curve Finance, a stablecoin-focused decentralized exchange, has fallen 2.8% in the past 24 hours, according to CoinGecko. Aave has fallen nearly 9% in the same period, and the tokens tied to Compound and the Synthetix network were down 10% and 7.3%, respectively.

Curve, a stablecoin exchange built on Ethereum, was exploited Sunday due to a bug in the smart contract programming language called Vyper. The hacker targeted three liquidity pools for tokens paired with ether and CRV as well as several ERC-20 tokens issued on Alchemix (alETH), Metronome Synth (smETH) and JPEG’d (pETH). It drained as much as $100 million worth of cryptocurrency from the platform, including $20 million of CRV and a version of ether, according to CryptoQuant.

“We’ve unfortunately had this scenario in crypto a few times over the past 12 to 18 months. Whenever investors hear the word hack … it puts the whole crypto market on the backfoot and that’s what’s happening here,” Gilbert said.

Bitcoin volumes have also dropped significantly from their recent highs and have failed to reclaim them despite the price of bitcoin showing so much resilience this year. It traded in a tight range throughout July, neither breaking above the key level of $31,500 nor below the $25,200, and it’s up 74% for the year.

“We had a lot of buzz recently around the Blackrock ETF but that can only drive bitcoin for so long and for so far. We got plenty of optimism with it but that initial optimism is fading slightly,” Gilbert said. “When bitcoin heads south so do most altcoins … and they’re selling off a little bit further given what we’re seeing with Curve.”

Tech, semiconductor stocks bounce on tariff optimism, Nvidia jumps 7%

Technology stocks bounced Tuesday after three rocky trading sessions, spurred by rising optimism that President Donald Trump could potentially negotiate tariff deals with world leaders.

Nvidia led the Magnificent Seven group’s gains, rallying about 7%. Meta Platforms, Amazon, Tesla, Apple and Microsoft jumped at least 4% each. Alphabet rose about 3%.

The sector is coming off a wild trading session after speculation that the White House could potentially delay tariffs fueled volatile swings. Alphabet, Meta Platforms, Amazon and Nvidia finished higher, while Apple, Microsoft and Tesla posted losses.

Trump’s wide-sweeping tariff plans have sparked violent turbulence over the last three trading sessions. Trading volume on Monday hit its highest in nearly two decades. Technology stocks gyrated after the Nasdaq Composite posted its worst week in five years and the Magnificent Seven group lost $1.8 trillion in market value over two trading sessions.

Semiconductor stocks also rebounded Tuesday, with the VanEck Semiconductor ETF jumping more than 5% to build on a more than 2% gain from the previous session. Advanced Micro Devices, Lam Research and Micron Technology jumped about 6%.

Chipmakers were excluded from the recent tariffs, but have come under pressure on worries that higher duties could diminish demand for products they are used in and slow the economy. The sector is also expected to see tariffs further down the road.

Elsewhere, Broadcom surged 9% after announcing a $10 billion share buyback plan through the end of the year. Marvell Technology also bounced more than 9% after agreeing to sell its auto ethernet business for $2.5 billion in cash to Infineon Technologies.

Digital health startup Transcarent takes Accolade private in 1 million deal

Digital health startup Transcarent on Tuesday announced it completed its acquisition of Accolade in a deal valued at roughly $621 million. 

Transcarent first announced the acquisition in January, and the company said it has received all necessary shareholder and regulatory approvals to carry out the transaction. Accolade shareholders received $7.03 per share in cash, and its common stock will no longer trade on the Nasdaq, according to a release.

“Adding Accolade’s people and capabilities will significantly enhance our existing offerings,” Transcarent CEO Glen Tullman said in a statement. “We’re creating an entirely new way to experience health and care. We are truly better together.” 

Transcarent offers at-risk pricing models to self-insured employers to help their workers quickly access care and navigate benefits. As of May, the company had raised around $450 million at a valuation of $2.2 billion. Transcarent also earned a spot on CNBC’s Disruptor 50 list last year.

Accolade offers care delivery, navigation and advocacy services. The company went public during the Covid pandemic in 2020 as investors began pouring billions of dollars into digital health, but the stock tumbled in the years following.

Accolade is the latest in a string of digital health companies to exit the public markets as the sector struggles to adjust to a more muted growth environment. 

Transcarent said the executive leadership team will report to Tullman and includes representatives from both organizations. Accolade’s Kristen Bruzek will serve as executive vice president of care delivery operations, for instance.  

Tullman is no stranger to overseeing major deals in digital health. He previously helmed Livongo, which was acquired by the virtual-care provider Teladoc in a 2020 agreement that valued the company at $18.5 billion.

General Catalyst and Tullman’s 62 Ventures led the acquisition’s financing, with additional participation from new and existing investors, the release said. The companies also leveraged cash from their combined balance sheet, and JP Morgan led the debt financing.

Drone delivery startup Zipline expands to Texas with Walmart partnership

Drone delivery startup Zipline expands to Texas with Walmart partnership

Zipline, a startup that delivers everything from vaccines to ice cream via electric autonomous drones, expanded its service to the Dallas area on Tuesday through a partnership with Walmart.

In Mesquite, Texas, about 15 miles east of Dallas, Walmart customers can sign up to receive orders within 30 minutes, delivered on Zipline’s newest unmanned aerial vehicles, known as P2 Zips.

The drones are capable of carrying up to eight pounds worth of cargo within a 10-mile radius, and can land a package on a space as small as a table or doorstep. The company, which ranked 21st on CNBC’s 2024 Disruptor 50 list, plans to expand soon in the Dallas metropolitan area.

Zipline CEO and co-founder Keller Rinaudo Cliffton said P2 Zips have “dinner plate-level” accuracy. They employ lift and cruise propellers and feature a fixed wing that helps them maneuver quietly, even through rain or gusts of wind up to 45 miles per hour.

In the delivery process, a P2 Zip will hover around 300 feet above ground level and dispatch a mini-aircraft with a container called the delivery zip, which descends on a long tether and moves into place using fan-like thrusters before setting down and allowing package retrieval.

Both the P2 Zip and the delivery zip use cameras, other sensors and Nvidia chips to determine what’s happening in the environment around them, and to avoid obstacles while making a delivery.

In March 2025, Zipline announced that its drones have logged more than 100 million autonomous miles of flight to-date, a number equivalent to flying more than 4,000 loops around the planet, or 200 lunar round trips, the company said in a video to mark the milestone.

Since it began operations in 2016, Rinaudo Cliffton said, Zipline has completed around 1.5 million deliveries, far more than competitors in the West. Wing, a Zipline rival focused on residential deliveries, has reported more than 450,000 deliveries since 2012.

Zipline initially focused on logistics in health care, making deliveries by drone to clinics and hospitals in nations where infrastructure sometimes impeded timely access to life-saving medicines, blood, vaccines and personal protective equipment. The company, valued at $4.2 billion in a 2023 financing round, is now making deliveries in Rwanda, Ghana, Nigeria, Côte d’Ivoire, Kenya, Japan and the U.S., and expanded well beyond hospitals and clinics.

In addition to Walmart, customers include Sweetgreen, Chipotle and other quick-serve restaurants, as well as health clinics and hospital systems such as Cleveland Clinic and Mayo Clinic.

Zipline’s launch in Mesquite comes days after President Donald Trump’s announcement of widespread tariffs roiled markets on concern that companies would face rising costs and a slowdown in consumers spending. Rinaudo Cliffton said he doesn’t anticipate massive impediments to Zipline’s business, as its drones are built in the U.S., with manufacturing and testing in South San Francisco.
