Rounds
Nuclear startup Blue Energy raised $380M (equity + debt) led by VXI Capital to build prefabricated nuclear reactors in existing shipyards for AI data centers. The MIT spinout's approach reduces capital costs from $10K/kW to $2K/kW and build times from 10 years to 2. First project: a 1.5 GW plant in Port of Victoria, Texas, partnered with Crusoe for AI data centers, with construction starting Q3 2026 and nuclear power by 2031. After Valar Atomics ($450M on Apr 4), Blue Energy is the second nuclear-for-AI startup to raise a mega round this month. Total raised: $425M.
Autonomous aircraft company Reliable Robotics raised $160M Series D at ~$1B valuation, led by Nimble Partners. Founded by former SpaceX Director of Flight Software Robert Rose and SpaceX avionics lead Juerg Frefel, the company builds the first FAA-certifiable system for fully automated operation of existing fixed-wing aircraft. Selected for the DOT eIPP advanced aviation pilot program with commitments for 200+ systems from commercial and military customers. Total raised: ~$300M.
News & Signals
Trump extends ceasefire hours before expiration, blockade remains
In a dramatic last-minute move, Trump extended the US-Iran ceasefire hours before it was set to expire on Tuesday April 22, citing Iran's 'seriously fractured' government and Pakistan's mediation request. The naval blockade of Iranian ports remains in effect. US officials gave Iran 3-5 days to engage in negotiations. But Iran seized two ships in the Strait of Hormuz in retaliation, refusing to negotiate 'under shadow of threats.' The S&P recovered to a new all-time high on Tuesday (+0.8-1.05%) on the ceasefire extension news.
Meta will track employee keystrokes and screen activity to train AI, no opt-out
Meta began installing 'Model Capability Initiative' (MCI) tracking software on employee laptops to capture keystrokes, mouse movements, and screenshots to train AI agents. There is no opt-out. The tracking covers activity across Google, LinkedIn, Wikipedia, GitHub, Slack, and Atlassian. CTO Bosworth: 'There is no option to opt out.' Employees are upset. The move represents the most aggressive corporate AI training data collection yet announced, and raises questions about whether other tech companies will follow.
SpaceX-Cursor $60B deal details emerge: acquisition option + $10B collaboration fee
More details emerged on SpaceX's preemption of Cursor's $2B fundraise. SpaceX (merged with xAI) offered a $10B 'collaboration fee' upfront and the right to acquire Cursor for $60B after SpaceX's summer IPO. Microsoft had also explored buying Cursor. Cursor halted its fundraise to evaluate the offer. The deal would create the most vertically integrated AI development stack in the industry: xAI's Grok models powering Cursor's code editor, all within SpaceX's infrastructure.
Boeing and Tesla Q1 earnings: defense wins, EVs under pressure
Boeing reported revenue of $22.22B (beating $21.78B est.) with 143 planes delivered (+10% YoY) and a record $695B backlog. Tesla reported revenue of $22.39B (missing $22.64B est.) but beat on EPS ($0.41 vs $0.37 est.) with gross margins up 478bps YoY to 21.1%. However, Tesla raised capex guidance to $25B from $20B. The pattern: defense and aerospace (Boeing) are thriving on the Iran war tailwind, while consumer EV (Tesla) faces margin pressure from the $99/bbl oil environment that paradoxically helps EVs compete but squeezes margins on everything else.
VC Mood on X
Monday's mood was defined by infrastructure conviction despite geopolitical noise. "Blue Energy $380M for nuclear reactors, Reliable Robotics $160M for autonomous aircraft, Valar Atomics $450M two weeks ago. The market is telling you the next decade of venture returns will come from atoms, not bits," one deep-tech investor posted. The nuclear-for-AI thesis now has two unicorn-track companies (Valar and Blue Energy) raising nearly $1B combined in April alone.
The Meta keystroke tracking story was the most discussed corporate news. "Meta is recording every keystroke, mouse movement, and screenshot from its employees to train AI. No opt-out. This is where the 'AI needs data' thesis meets the 'employee rights' wall," one enterprise investor posted. The question cascading through VC portfolios: will other employers follow? If so, the market for enterprise AI training data becomes radically cheaper, but the legal and HR implications are uncharted.
The ceasefire extension was read as a net positive but not a resolution. "Trump extended because he needs time, not because there is a deal. Iran seized two ships the same day. We are in a holding pattern, not a peace process," one geopolitics-focused investor posted. DB at 800 companies.
