Constraint Is the New Strategy: GPU Prices Surge, Tech Founders Buy Banks, and PE Bets on Patience
Nvidia Blackwell GPU rentals hit $4.08 an hour — up 48% in two months. OpenAI signs its first permanent London office. Nir Zuk agrees to buy a California bank. And Eurazeo posts record fundraising while the headlines look elsewhere.
This week didn't produce a single defining headline. What it produced instead was something harder to summarise but more useful to track: a series of signals suggesting that the global tech economy is entering a phase shaped less by ambition and more by constraint. Compute is getting scarce and expensive. AI expansion is running into energy limits and regulatory friction in Europe. Fintech's boldest players are buying actual banks rather than building around them. And the private equity managers posting the strongest fundraising numbers are doing it with the least glamorous strategy imaginable — buying assets, holding them, and waiting.
These aren't disconnected stories. They share an underlying logic. The easy phase of AI deployment — the phase where you could build fast, test broadly, and figure out unit economics later — appears to be closing. What's replacing it requires more discipline, more patience, and more willingness to engage with the parts of the economy that were never going to be disrupted overnight. Physical infrastructure. Banking licences. Long-duration income assets. The stuff that doesn't go viral.
Here's what the week looked like, with the numbers checked and the hype filtered out.
AI: The Compute Shortage Is Now an Industry-Wide Problem
The Ornn Compute Price Index, published on the Bloomberg Terminal on April 13, confirmed something that AI infrastructure teams had been feeling for weeks: Nvidia Blackwell GPU rental prices hit $4.08 per hour — a 48% rise from $2.75 just two months ago. The cause, according to Vultr CEO J.J. Kardwell, is straightforward: "This is the most severe compute shortage I've seen in over five years of running this company. Data center construction cycles are too long. All electricity capacity available through 2026 has already been reserved."
The consequences are showing up at the product level. Anthropic's Claude API recorded 90-day uptime of 98.95% as of April 8 — below the industry standard of 99.99%. That's the kind of reliability gap that affects enterprise procurement decisions in a real way. Retool's founder and CEO David Hsu said publicly this week that he considers Claude the best enterprise model but switched to OpenAI because "Anthropic has been constantly down." In late March, Anthropic began limiting user token consumption on weekday mornings — a visible sign of supply pressure. Nvidia's Blackwell hardware remains on backorder, with a reported backlog of approximately 3.6 million units. Analysts expect the imbalance to persist until at least 2029.
Against that backdrop, OpenAI's London announcement on April 13 looked like two stories at once. The company signed a lease for 88,500 square feet at Regent's Quarter in King's Cross — capacity for over 500 employees, more than double its current 200-person UK headcount. London will become its largest research hub outside San Francisco. That part is an expansion story. The other part is less positive: OpenAI paused its UK Stargate infrastructure project earlier this month, citing high energy costs and regulatory hurdles. Talks with project partner Nscale are continuing, but the data centre build is on hold. So the talent is coming. The compute may not follow as fast as planned.
The broader AI picture this week is one of a sector running up against physical limits that software ambition alone can't solve. Energy availability, data centre construction timelines, and hardware supply chains don't respond to funding announcements. For the enterprises trying to deploy AI at scale, those physical constraints are becoming the dominant planning variable — more so than model capability.
Startups: A Two-Speed Market, and the Gap Is Widening
The startup funding environment in the week of April 12 reinforced what Q1's record $300 billion quarter had already made clear: capital is flowing toward AI at a pace that leaves most other sectors competing for what's left. OECD data puts AI's share of global VC at 61% in 2025 — up from roughly 30% in 2022. That's not a rebalancing. It's a structural shift.
In Europe specifically, AI ventures now account for over 60% of VC deal value. There are approximately 11,000 active AI startups across the region, according to industry analysis published this week. That's a lot of companies competing for a relatively thin slice of capital below the tier of companies large enough to attract transatlantic mega-rounds. The Foley & Lardner April 2026 market report noted that horizontal application software has fallen 21% since ChatGPT launched in late 2022. Vertical software is down 34% in the last twelve months. The AI infrastructure tier, by contrast, is up 473% over the same period.
What's getting funded below the megaround tier follows a consistent pattern: companies with proprietary data, embedded workflows, and clear enterprise revenue paths. Legal AI, compliance automation, healthcare workflows, and industrial operations platforms are all drawing capital. The playbook has shifted from "build with AI" to "build something that only becomes possible because of AI." Founders who can demonstrate that distinction — with specific numbers and customer evidence — appear to be finding Series A and B rounds. Those who can't are finding the process considerably longer.
Fintech: The Banking Layer Itself Is Now in Play
The most interesting fintech story of the week wasn't a payments app or a stablecoin announcement. It was Nir Zuk, founder of Palo Alto Networks and co-founder of agentic banking platform eOS, agreeing to acquire Liberty Bank in Irvine, California — a $440 million community lender — as a launchpad for AI-native financial services. Zuk applied to the Federal Reserve Bank of San Francisco under the Change in Bank Control Act. Fintech investors Betsy and Daniel Cohen are expected to join the deal.
Columbia University professor Todd Baker described it plainly to American Banker: this appears to be "a demonstration project." The goal is to introduce AI-based core banking systems into a small US bank "in a low-risk, small-scale way" — and if it works, use Liberty as a template for wider expansion. Zuk already ran a version of this in Israel through Esh Bank, which now operates on eOS's agentic platform covering core banking, payments, loans, and compliance. If Liberty gets regulatory approval, it would be eOS's first US deployment.
Zuk isn't alone in this direction. Palmer Luckey's Erebor Bank received a national banking charter in February. OpenAI acquired the personal finance platform Hiro this week. Elon Musk has signalled plans for X Money. The pattern, as Banking Dive noted, is that "tech billionaires and firms" are moving directly into the regulated financial system rather than building around it. That's a different kind of disruption from what fintech has typically attempted — and in a friendlier regulatory environment, more of it seems likely.
Separately, Paradigm — the crypto VC firm that launched the largest dedicated crypto fund in history in 2021 — confirmed in late February it is raising a new $1.5 billion fund that will invest in AI, robotics, and frontier technologies alongside crypto. The move reflects a practical recognition that the sector boundaries between crypto, AI, and fintech are dissolving. One concrete application Paradigm has been exploring: agent-driven payments, where autonomous AI systems execute transactions using blockchain rails. That intersection of AI decision-making and programmable settlement may generate more durable investment theses than either technology alone.
European PE: Patience Is Paying Off
While the AI funding cycle generates most of the week's headlines, European private equity managers are quietly posting some of the most consistent performance numbers in the market. Eurazeo reported record fundraising of €5.5 billion in 2025 — up 28% year on year, marking three consecutive years of annual fundraising growth above 20%. Total AUM reached €39 billion, up 8% year on year. The co-CEOs described 2026 as an environment where "capital rotation is outpacing the market," with exits and redeployment moving at pace. Significant exit volume is expected through the year.
The firm's positioning — mid-market European companies, private debt, infrastructure, and real estate — hasn't changed dramatically. What's changed is the macro environment around it. With interest rates moderating, bid-ask spreads narrowing on real assets, and US investors increasingly interested in European entry valuations (PitchBook expects US investors to account for one in four European PE deals in 2026), the strategy that looked cautious in 2022 looks well-positioned now. Eurazeo's co-CEOs put it simply: "In a polarised market, Eurazeo consolidated its position as a leading player in the European mid-market."
The EQT-Coller Capital deal, announced in January and now progressing toward a Q3 close, adds another dimension. EQT agreed to acquire Coller Capital for up to $3.7 billion — entering the secondaries market where deal volume hit $226 billion in 2025, up 41%, and is expected to more than double by 2030. The secondaries market exists, at its core, because private equity holding periods are extending. LPs need liquidity options that don't depend on IPO windows or trade buyers. EQT's move — paying a full price to acquire 35-year secondaries expertise and $50 billion in AUM — is a bet that liquidity management will become as important as deal origination in the next phase of private markets.
The underlying logic of European PE this week was the same as it has been for two years: buy cash-generating assets at reasonable entry prices, optimise operations, hold through volatility, and let compounding do its work. In a market where AI infrastructure is consuming capital at extraordinary rates and compute is physically constrained, that approach looks less conservative than it might have a year ago.

Four Things to Watch Next Week
Zuk's Federal Reserve application has a comment deadline of April 30. Watch for regulatory responses and whether any competing bids or objections emerge before then.
OpenAI paused the UK data centre project over energy costs and regulation. Any resolution — or further delay — with Nscale will signal how quickly European AI infrastructure build-out can actually happen.
With Claude API uptime below the 99.99% industry standard, enterprise customers are making decisions. Watch for whether CoreWeave's multi-year Anthropic supply deal changes the reliability picture.
Management flagged "significant exit volume expected in 2026." Q2 transaction announcements from the European mid-market will test whether the exit environment is actually improving or still constrained.
The thread through this week's stories may be simpler than it looks: constraint is forcing a kind of precision that the last few years of AI expansion didn't require. GPUs are scarce. Energy is scarce. Banking licences take time. Long-duration assets require patience. The companies — and investors — adapting to those realities now are likely to look better positioned in two years than those still optimising for speed alone.
