Amazon commits up to $25bn more to Anthropic in decade-long cloud deal

Amazon will invest up to an additional $25bn in Anthropic, extending a relationship that already made Amazon the AI startup's largest backer.
In return, Anthropic has committed to spending more than $100bn on Amazon Web Services cloud infrastructure over the next decade.
The expanded collaboration includes joint development of up to 5 gigawatts of new compute capacity.
Anthropic's $5bn funding tranche, reported separately, is part of the broader infrastructure and investment agreement.
The deal deepens Anthropic's dependence on AWS as its primary cloud and compute provider, concentrating infrastructure risk with a single hyperscaler.

Why it matters: Anthropic committing over $100bn in AWS spend across a decade converts what was a financial investment into a structural revenue guarantee for AWS. This reduces AWS revenue volatility tied to AI…

Arbitrum freezes $71M in ETH linked to Kelp DAO exploit

Arbitrum's security council froze 30,766 ETH worth approximately $71 million connected to an exploit of Kelp DAO.
The funds were moved to an intermediary wallet that cannot be accessed without a further Arbitrum governance decision.
Council member Griff Green said the action was taken with input from law enforcement and was not made lightly.
The freeze represents a direct intervention by a layer-2 network's governance body into on-chain asset movement, a step with significant precedent implications for decentralised networks.

Why it matters: Arbitrum's freeze establishes that layer-2 governance councils can unilaterally immobilize on-chain assets in response to exploits, with law enforcement coordination. This directly reprices the…

Bank of Korea governor backs CBDC and deposit tokens, silent on stablecoins

Shin Hyun-song, who began his four-year term on Tuesday, pledged to advance Project Hangang's second phase, a wholesale blockchain-based CBDC pilot, and to expand deposit token use.
Shin made no mention of won-pegged stablecoins despite active South Korean legislative efforts to legalise them under the Digital Asset Basic Act, with discussions expected to resume after June 3 elections.
During his tenure as BIS head of the Monetary and Economic Department, Shin published a paper arguing stablecoins fail the monetary property of 'unity' due to blockchain fragmentation across chains with differing fees, security and decentralisation.
The BOK had reportedly paused its CBDC work last year as stablecoin momentum grew; the new governor's address suggests a reorientation back toward central bank-controlled digital instruments.
South Korea's Ministry of Economy and Finance is separately preparing a tokenized deposit pilot for selected government expenses, with a full rollout targeted for Q4 2026 beginning in Sejong City.
Shin also cited plans to modernise currency markets for 24-hour foreign exchange trading and to increase scrutiny of crypto markets and non-bank finance.

Why it matters: The BOK governor's explicit endorsement of Project Hangang Phase 2 and deposit tokens, combined with silence on won-pegged stablecoins, signals that South Korea's central bank will actively compete…

Crypto scammers impersonate Iranian authorities to extort stranded Hormuz shipping

Greek maritime risk firm Marisks warned on Monday that unknown actors are sending shipping companies fraudulent messages posing as Iranian security services and demanding bitcoin or USDT for Strait of Hormuz transit clearance.
Marisks believes at least one vessel targeted by Iranian gunfire on April 18 had received and acted on these fraudulent instructions before attempting to transit the strait.
Roughly 20,000 oil tankers and freighters remain stranded in the Gulf following Iran's closure of the strait from late February and a subsequent U.S. Naval blockade imposed approximately a week ago.
The scam is credible to recipients because Iran itself proposed on April 9 to charge legitimate crypto tolls for transit, with spokesperson Hamid Hosseini indicating fees of around $1 per barrel of oil payable in bitcoin.
Chainalysis senior intelligence analyst Kaitlin Martin warned that any cryptocurrency payments linked to Iranian-controlled waterways could constitute 'material support' under U.S. And international sanctions, including those targeting the Islamic Revolutionary Guard Corps.
A temporary U.S.-Iran ceasefire is set to expire on April 23, with no certainty that a second round of talks in Pakistan will proceed.

Why it matters: Iran's April 9 proposal to charge crypto tolls for Hormuz transit, now being exploited by scammers, creates a sanctions minefield for any shipping company that pays either party. Chainalysis's…

UnitedHealth beats Q1 estimates by widest margin in five years, raises full-year outlook

UnitedHealth posted quarterly profit above Wall Street estimates, with the beat described as the widest margin in five years.
The company raised its full-year profit outlook, signalling management confidence that cost pressures are abating.
Medical costs, which had weighed heavily on prior results, showed signs of improvement in the quarter.
Management detailed corporate changes alongside the results, indicating structural as well as financial repositioning.
The stock surged on the earnings release, leading the Dow Jones index on the day.

Why it matters: UNH's widest beat in five years, combined with a raised full-year outlook and explicit signals that medical cost trends are improving, directly challenges the sector-wide narrative that post-pandemic…

The listing raised HK$20 billion (US$2.6 billion), the largest Hong Kong IPO so far this year.

The company's Shenzhen-listed shares have risen fourfold over the past year, reflecting sustained investor demand for AI infrastructure components.
Victory Giant is chaired by billionaire Chen Tao.

Why it matters: Victory Giant's 50% debut pop on a $2.6bn raise confirms that Hong Kong investors are willing to pay a significant premium for direct Nvidia supply chain exposure at a time when AI infrastructure…

DoorDash adopts stablecoin payouts via Stripe-backed Tempo blockchain

DoorDash will use Tempo, a payments blockchain co-developed by Stripe and Paradigm, to issue stablecoin payouts to merchants and Dashers across more than 40 countries.
The rollout starts with cross-border payout flows where settlement speed and cost differences are most acute; exact go-live timing was not disclosed.
Stripe is deploying Tempo as core infrastructure for its money-management products, enabling businesses in more than 100 countries to hold, send and receive stablecoins alongside traditional currencies.
Coastal Bank and Latin American fintech ARQ are also running stablecoin payment operations on Tempo, covering markets including Mexico, Colombia, Argentina and Brazil.
Tempo, which launched last month with Mastercard, UBS, Klarna and Visa as infrastructure partners, offers sub-second settlement, fixed dollar-denominated fees and private transaction channels designed for enterprise payment workloads.
Stripe previously acquired stablecoin infrastructure firm Bridge for $1.1 billion in 2024 and crypto wallet provider Privy, building out a stablecoin stack that now processes parts of its nearly $2 trillion in annual payment flows.

Why it matters: Stripe's deployment of Tempo across DoorDash, Coastal Bank, and ARQ, combined with the Bridge and Privy acquisitions, positions Stripe as the dominant enterprise stablecoin rails operator before any…

Trump blocks United-American merger talk, seeks buyer for Spirit Airlines

President Trump stated his opposition to a potential United Airlines-American Airlines merger, effectively cooling speculation about a large-scale domestic airline consolidation.
American Airlines CEO dismissed talk of a United megamerger, triggering a decline in American's share price.
Trump separately said he wants 'somebody' to buy Spirit Airlines, which is in active talks with the Trump administration about a potential government investment.
Transportation Secretary characterised United CEO's proposal to acquire American as 'interesting', signalling the administration is engaging with industry proposals selectively rather than categorically blocking consolidation.
Bipartisan senators have separately pressed the CEOs of United and American on the reported merger, adding congressional scrutiny to the regulatory and White House pressure.

Why it matters: Trump's opposition to a UAL-AAL merger removes the primary re-rating catalyst for American Airlines equity, which had been trading with a consolidation premium embedded. AAL reverts to being valued…

Iran war drives jet fuel shortage, pushing airfares up 24% ahead of summer

Air fares have risen approximately 24% as the Iran war disrupts jet fuel supply chains and forces flight rerouting, according to research cited by the BBC.
Long-haul flight costs have increased by around $100 per ticket due to the fuel price impact, per a Reuters-cited study.
Airlines are warning of an imminent jet fuel shortage severe enough to threaten summer flight schedules, with some carriers already cancelling routes or adding fuel surcharges.
The Dutch government confirmed the EU holds production and reserves equivalent to five months of jet fuel supply, offering partial reassurance on near-term availability.
UK carriers are lobbying the government to relax noise regulations and cut flight taxes as the fuel crunch tightens operational constraints.

Why it matters: The EU's five-month reserve buffer, combined with the IEA's earlier six-week warning, suggests the depletion window has already partially consumed. European network carriers with low hedge ratios and…

EU battery EV registrations surge 51% in March as Iran war lifts fuel costs

BEV registrations in 15 key EU and EFTA markets rose 51% month-on-month in March to 224,000 units, according to New Automotive and E-Mobility Europe.
EVs accounted for 22% of all new passenger car sales in those markets during the month, the highest share on record for the period.
First-quarter registrations totalled 500,000 units, a 33.5% increase on the same period a year earlier, indicating the March spike is part of a broader trend rather than a single-month anomaly.
The primary demand driver cited is the Iran war pushing gasoline and diesel prices to multi-year highs, prompting consumers to accelerate switches away from combustion-engine vehicles.
Chinese EV brands are positioned to capture a disproportionate share of incremental demand, potentially accelerating their European market penetration.

Why it matters: Chinese EV brands, led by BYD and SAIC, are the structural beneficiaries of Iran-war-driven fuel cost acceleration in Europe. Legacy European OEMs with higher BEV cost bases and slower model rollouts…
