AI Startup Funding Tracker
June 2026's top 15 funding rounds totaling $7.2B+ across AI inference infrastructure, fintech, cybersecurity, defense tech, space tech, and foundational AI
Baseten
The AI inference layer just became the most fundable segment in the entire AI stack — Baseten's $1.5B Series F, split across two tranches at $13B and $11B, reflects surging demand for infrastructure that runs models rather than builds them
Baseten, the San Francisco-based AI inference company, raised $1.5 billion in Series F funding led by Altimeter Capital, Conviction, and Spark Capital, with Sands Capital and Wellington Management as co-leads, plus IVP, Greylock, 01A, Blackbird, Durable Capital Partners, Verified Capital, Battery Ventures, and D.E. Shaw Ventures participating. The round closed across two tranches at $13 billion and $11 billion valuations. Baseten's platform manages GPU orchestration, autoscaling, observability, billing, and developer tooling so companies can deploy multi-model strategies combining frontier models with custom, post-trained models. Revenue has grown roughly 20x year-over-year, with the platform now processing more than one billion inference calls daily across 87 clusters spanning 18 clouds. Customers include Abridge, Clay, Cursor, Lovable, Mercor, and OpenEvidence. Capital will fund tripled headcount, expanded compute, and enterprise go-to-market.
Ramp
The seven-year-old spend-management platform sets a $44B valuation, making it one of the most highly valued private fintech companies in the US and the month's biggest non-AI-labeled megaround
New York-based Ramp, the spend-management software provider, secured $750 million in growth financing led by Iconiq, GIC, and Ontario Teachers' Pension Plan. The round set a $44 billion valuation for the seven-year-old company, ranking it among the most highly valued US fintech startups. Ramp's platform combines corporate cards, expense management, bill pay, and AI-driven finance automation for businesses, and the raise came in the same opening week of June that saw GIC anchor two separate nine-figure rounds — the other being Supabase.
Cyera
Valuation quadruples in 18 months to $12B as Cyera positions itself as the "trust layer" enterprises need to know what their AI agents can see and do — even as critics flag an 80x ARR multiple
Cyera raised $600 million led by Evolution Equity Partners, with participation from Cyberstarts and Temasek alongside existing investors Accel, AT&T Ventures, Blackstone, Coatue, and Spark Capital. The round quadruples Cyera's valuation over 18 months — from $3B in late 2024 to $6B (June 2025), $9B (January 2026), and now $12B — and pushes total funding past $2 billion. Cyera's AI-native platform discovers and classifies enterprise data at rest, in motion, and in use, and governs what AI agents can access. The company has passed $150 million in ARR, tripled revenue three years running, grown to 1,500+ employees across 18 countries, and completed five acquisitions including Ryft and Genie. Customers include Paramount, Chipotle, and Valvoline.
Impulse Space
Spacecraft and propulsion developer crosses $1B in total funding as demand grows for orbital transport and repositioning services beyond launch
Redondo Beach, California-based Impulse Space, a developer of spacecraft and propulsion systems for orbital transport and repositioning, raised $500 million in Series D funding led by 137 Ventures and Banner VC. The round brings the company's total investment to over $1 billion. Impulse Space builds in-space mobility vehicles that move payloads between orbits after launch — a capability increasingly in demand as satellite constellations and defense payloads require more flexible orbital placement than a rocket alone can provide.
Supabase
The open-source Firebase alternative sets a $10.5B valuation as GIC backs two separate nine-figure AI-adjacent rounds in the same week
Supabase, provider of an open-source platform for developers and AI app builders, closed $500 million in fresh funding led by GIC, setting a $10.5 billion valuation for the San Francisco-based company. Supabase provides a Postgres-based backend-as-a-service used heavily by AI-native startups to ship apps quickly, and its growth has tracked the broader AI app-building boom as more products embed generative AI features directly into their backend infrastructure.
Flourish
One of the largest seed-stage rounds ever recorded — $500M in initial funding for a New York startup building AI models inspired by the architecture of the human brain
Flourish, a New York-based startup building AI models inspired by the human brain, raised $500 million in initial seed-stage funding, with backers including Jeff Bezos, Lux Capital, and Google Ventures. The round is one of the largest seed rounds in US startup history and continues 2026's pattern of investors backing early-stage foundational AI bets even as OpenAI and Anthropic dominate headlines — a wager that brain-inspired architectures could offer efficiency or capability advantages over today's transformer-based models.
Suno
AI music-generation tool raises at a $5.4B valuation while still facing active lawsuits from multiple major record labels over training data
Suno, provider of AI tools for making music, raised $400 million in Series D funding led by Bond, setting a $5.4 billion valuation. The round arrived as Suno continues to face lawsuits from multiple music labels alleging its models were trained on copyrighted material without permission — litigation risk investors have so far priced through, given the product's rapid consumer adoption for text-to-song generation.
Generalist AI
San Mateo robotics startup targeting complex real-world physical tasks reaches a reported $2B valuation as physical AI attracts fresh capital alongside software-only bets
San Mateo, California-based Generalist AI, focused on AI-enabled robotics for complex real-world tasks, picked up $400 million in new funding led by Radical Ventures, reportedly at a $2 billion valuation. The company is part of a broader 2026 push into physical AI, where investors are betting that robotics capable of general-purpose manipulation and reasoning in unstructured environments represent the next major platform shift after language models.
AlphaSense
Nearly doubles its valuation to $7.5B on the back of $600M+ ARR — proof that AI-powered market and research intelligence is scaling as an enterprise software category
AlphaSense closed a $350 million funding round at a $7.5 billion valuation, nearly double its previous $4 billion mark, led by Vitruvian Partners, Accenture Ventures, and J.P. Morgan Asset Management, with D.E. Shaw Ventures, CapitalG, Goldman Sachs Alternatives, and Viking Global participating. The New York-based company, which uses AI to search and synthesize market intelligence, earnings calls, and research documents for corporate and financial clients, reported exceeding $600 million in annual recurring revenue in Q1 2026.

The Las Vegas "anti-Nvidia" cloud raises the largest Series B in Nevada history — an all-AMD alternative for memory-intensive AI workloads, nearly quadrupling its valuation in a year
TensorWave, the all-AMD AI cloud specializing in high-performance, memory-intensive workloads, raised $350 million in Series B funding co-led by Magnetar and AMD Ventures, with Maverick Silicon, Nexus Venture Partners, and Western Frontier participating. The round values the Las Vegas company at $1.55 billion, up from a $400 million valuation less than a year earlier. TensorWave runs one of the largest AMD-based AI training clusters in North America, with 8,192 Instinct MI325X GPUs online and more than 2 gigawatts of long-term data center capacity secured, positioning itself as an open-ecosystem alternative to capacity-constrained, Nvidia-dominated GPU supply chains.
General Intuition
A foundational AI model trained on gameplay mechanics raises at a $2.3B valuation — betting that video games are a rich, scalable training ground for spatial reasoning and agentic behavior
New York-based General Intuition, developer of a foundational AI model built on gameplay mechanics, secured $320 million in Series A funding at a $2.3 billion valuation, with Khosla Ventures leading and Jeff Bezos and General Catalyst participating. The company trains models on gameplay data to build spatial reasoning and real-time decision-making capabilities — a thesis that video games offer dense, structured, and scalable environments for training agentic AI systems beyond what static text or image datasets can provide.

Mach Industries
A three-year-old defense tech startup reaches a $1.8B valuation, confirming that national security AI and hardware remain a first-tier venture category alongside consumer and enterprise AI
Huntington Beach, California-based Mach Industries, a defense tech startup founded just three years ago, raised $300 million in Series C funding at a $1.8 billion valuation, led by Ribbit Capital and Infinite Capital. Mach Industries builds autonomous defense hardware and is one of several fast-growing defense tech companies — alongside Anduril and Peregrine Technologies — that raised significant capital in June 2026, underscoring institutional investors' growing appetite for national security technology.
Peregrine Technologies
AI software for public safety agencies hits a $6.8B valuation, placing govtech AI comfortably alongside top-tier enterprise SaaS on the strength of Sequoia's backing
San Francisco-based Peregrine Technologies, a provider of AI software for public safety agencies and government entities, secured $250 million in Series D financing led by Fifth Down Capital, Sequoia Capital, O.G. Venture Partners, and Goldcrest Capital, setting a $6.8 billion valuation. Peregrine's platform helps law enforcement and government agencies integrate and analyze disparate data sources in real time, and the round places it among the largest govtech AI valuations of 2026 — a category increasingly treated as a legitimate, well-capitalized venture segment rather than a niche.
Quantifind
Palo Alto risk intelligence platform closes $200M growth round as financial crime detection and national security analytics attract sustained institutional capital
Palo Alto-based Quantifind, developer of a risk intelligence platform for financial crime detection and national security, closed $200 million in growth financing led by Summit Partners. Quantifind's AI models help banks, fintechs, and government agencies screen for money laundering, sanctions evasion, and other financial crime risk signals across large, unstructured datasets — rounding out a strong June for AI applied to compliance, risk, and public-sector use cases alongside Peregrine Technologies and Taktile.
