Venture Funding Rounds This Week: Tenstorrent Leads, Billion-Dollar Series A (19–25 October 2026)

Venture funding rounds this week were defined by two very different billion-dollar cheques: a Series E for a ten-year-old chip company and a Series A for a one-year-old AI lab. For the week of 19–25 October 2026, Crunchbase News counted ten US rounds of $160M or more, adding up to about $4.3B, and Tech.eu tracked more than 65 European deals worth over €1.5B. This roundup is part of our venture capital and startup finance hub, and it follows last week’s roundup, which covered the quieter 12–18 October stretch led by Modal Labs. Every figure below is as reported by the cited source, and amounts described as “reported” have not been independently confirmed by the companies.

Which were the largest venture rounds this week?

Tenstorrent led with a $1.5B Series E, followed by Flapping Airplanes at $1B, Legora at $550M, Neolix at $400M and ASI at $325M. Eight rounds worldwide cleared the $200M mark.

Tenstorrent, the Santa Clara AI processor company led by chip architect Jim Keller, raised $1.5B in a Series E that Crunchbase News reports was led by Trace Capital and Innovation X and valued the ten-year-old business at $6.2B. The round is the largest US venture deal since Databricks and River AI in August, and it reinforces the thesis that investors are willing to fund alternatives to Nvidia at the silicon layer rather than only at the model layer. Right behind it, Flapping Airplanes, an AI lab that is barely a year old, closed a $1B Series A led by Lux Capital and Index Ventures. TechCrunch puts the valuation at $6B, and Crunchbase notes the round came less than ten months after a $180M seed. The company is working on models that are cheaper to train and run, which is exactly the efficiency pitch that has become fashionable as compute bills balloon.

Europe produced the third-largest deal. Swedish legal AI company Legora raised $550M in a Series E led by Atreides Management at an $8.8B valuation, according to Tech.eu, up from $5.6B at its $600M Series D roughly six months earlier. In China, driverless delivery vehicle maker Neolix raised a $400M Series E led by Boyu Capital, with Alibaba’s AEF NextGen Fund, Monolith Management, Granite Asia and Vertex joining, as reported by Dealroom. Back in the US, Boston-based ASI took $325M in a Series C led by Spark Capital at a reported $3B valuation to build AI for critical infrastructure, Xona Space Systems raised a $250M Series D led by Future Ventures at a reported $2.45B valuation for its satellite navigation constellation, and Pathos AI secured $237M in a Series E led by Bristol-Myers Squibb at a post-money valuation of around $3B.

The $200M tier was unusually crowded. Warp Sciences raised a $215M Series A led by Lightspeed for AI and robotics in life sciences. Whop, a marketplace for online businesses, took a $200M Series D co-led by Sequoia and Shopify Ventures at a $5.1B valuation. Star Therapeutics raised $200M from OrbiMed and Janus Henderson after Incyte bought its subsidiary Vega earlier in the year. And Warhound, co-founded by Anduril founder Palmer Luckey and Colossal’s Ben Lamm, emerged from stealth with a $200M seed to breed and equip military working dogs. Arda Industries rounded out the top ten with a $160M Series A led by Altimeter, Accel and Khosla Ventures at a $1.5B valuation, on top of a previously undisclosed $72M seed. The table below lists the fifteen rounds we consider most significant for the week.

Where did the money go by sector?

AI infrastructure and AI-native software took the bulk of dollars, followed by biotech and health, defense and space, and industrial software. Fintech remained subdued, consistent with Crunchbase’s Q3 data.

Of the ten largest US rounds, at least seven are AI-first businesses: Tenstorrent (silicon), Flapping Airplanes (models), ASI (infrastructure AI), Pathos (AI drug development), Warp Sciences (AI and robotics for life sciences), Arda (AI for manufacturing) and Whop, which markets itself around AI-enabled commerce tooling. Add Legora, Pigment, Blackwall, Daytona and Tractian from outside the US top ten and the pattern is unmistakable: the applied-AI layer is now absorbing growth capital at the same pace the model layer did eighteen months ago. Our analysis of venture capital investment by sector from 2024 to 2026 tracks how this concentration has built up over multiple quarters.

Biotech and health had a solid week beneath the AI headlines. Pathos AI ($237M), Star Therapeutics ($200M) and Warp Sciences ($215M) were all in the US top ten, and India’s largest deal was Even Health’s $50M Series B led by Khosla Ventures, which Inc42 reports pushed healthtech to $60.6M of the country’s weekly total. Defense and space continued their 2026 run: Xona ($250M), Warhound ($200M), Portugal’s Beyond Vision (over €28M for autonomous drones, co-led by Índico Capital and Lince Capital) and Israel’s Mave ($28M Series A led by Red Dot Capital for AI security agents) all closed. Industrial and physical AI was represented by Tractian’s $130M Series D led by Sapphire Ventures at a $1.4B valuation, Formic’s $50M mixed equity and debt round and Enact’s $30M pre-seed in Switzerland.

Fintech, by contrast, had a thin week. The notable rounds were Cognitive Credit ($40M strategic growth from Summit Partners, UK), Coast ($35M growth equity led by Thomvest, US) and Slingshot Insurance ($27M seed co-led by Rally Ventures and Skyward Group). That fits Crunchbase’s report, published on 20 October, that fintech funding fell 21% in Q3 2026 as deal counts thinned. Energy and climate saw Commonwealth Fusion Systems take $85M for fusion-ready semiconductors, per TechCrunch, and Cura Climate raise $10M for low-carbon cement in Calgary.

Which regions outside the US raised?

Europe rebounded to more than 65 deals worth over €1.5B, led by Sweden and France. India slowed to about $184M, China delivered a $400M robovan round, and MENA was quiet.

Europe. Tech.eu’s weekly tracking shows European tech raising over €1.5B across more than 65 deals, with four exits. Legora’s $550M Series E was the anchor, but Paris-based Pigment’s $250M Series E was arguably the more interesting signal: it was led by the Scaleup Europe Fund managed by EQT, the vehicle designed to keep late-stage European champions from relying solely on US growth investors, and The Next Web reports a $2.3B valuation with Nvidia planning to participate. Estonia’s Blackwall raised $100M in a Series C led by AVP at a $2.2B valuation, four times its 2025 mark, making it one of Europe’s most valuable cybersecurity scale-ups. Croatia’s Daytona hit a $1B valuation with a $60M Series B led by FirstMark for its AI agent cloud, becoming the country’s third unicorn according to Tech.eu. Smaller rounds included Enact ($30M pre-seed, Switzerland), Beyond Vision (over €28M, Portugal) and Foundational (£8.2M pre-seed, UK). For context on who writes these cheques, see our guide to the top venture capital firms in the UK and Europe.

India. Inc42 counted $184M across 17 deals for 19–23 October, down 22% in value and 32% in deal count from the prior week. AI led with $93.9M across six deals, including Different’s $48M seed led by General Catalyst and Lightspeed, AuxoAI’s $20.7M Series A led by NTTVC and Firstwork’s $15M Series A led by Earlybird. Even Health’s $50M Series B was the largest single round. DealStreetAsia also reported Premji Invest, Norwest and Lok Capital committing up to ₹1,000 crore (about $106M) to MSME lender Vegafin. Our directory of the top venture capital firms in India and Southeast Asia profiles the most active of these investors.

China, Japan and Korea. Neolix’s $400M Series E was the largest round in Greater China, and Dealroom describes it as the biggest robovan deal in China this year. DealStreetAsia noted that Suzhou Dongshan Precision filed for a Hong Kong listing of up to HK$10.67B, and that OrbiMed closed its sixth Asia healthcare fund at about $1.05B. The IPO market in Korea offered a warning sign, with data centre firm Elice reportedly falling 32% on debut.

Southeast Asia. The region’s headline was an exit rather than a round: Mynt, the parent of GCash, listed in Manila on 20 October at a valuation of around $7B and closed flat, per DealStreetAsia. Singapore’s Blue Whale Energy raised a $4M seed and Zevero added $8.33M.

Gulf, Israel and Türkiye. MENA had no mega-round; Wamda’s most recent large items were Saudi pre-seed deals such as Ghanem ($1.5M). Israel was represented by Mave’s $28M Series A and by Vintage Investment Partners, the Tel Aviv-founded fund-of-funds, which raised $920M in new capital. In Türkiye, Tech.eu recorded ACT Venture Partners backing drone communications start-up Arke Telekom with €1M. Our overview of the top venture capital firms in the Middle East, Türkiye and Israel explains why the region’s activity is so lumpy from week to week.

What seed and Series A rounds stood out?

Early-stage rounds were enormous by historical standards: a $1B Series A, a $215M Series A, a $200M seed and a $160M Series A all closed in the same week, alongside more conventional $10M to $50M deals.

The headline early-stage rounds were Flapping Airplanes ($1B Series A), Warp Sciences ($215M Series A), Warhound ($200M seed) and Arda Industries ($160M Series A). These are not “Series A” in any traditional sense; they are growth-sized bets on teams whose founders have already built something large. The pattern is a clear expression of the barbell effect we described earlier this year: capital clusters around proven operators at the very top and around capital-efficient seed companies at the bottom, with the middle squeezed.

Among the more conventional early rounds, several deserve attention. Different, the Indian AI company, raised a $48M seed led by General Catalyst and Lightspeed. Maxinsights in Santa Clara raised a $30M seed led by Peak XV Partners to collect first-person video as training data for robots; Crunchbase reports it has captured over two million hours of footage. Enact Intelligence in Switzerland took a $30M pre-seed from Redalpine, Notion Capital and Firstminute, with Yann LeCun and Mistral CEO Arthur Mensch among the angels. Slingshot Insurance raised a $27M seed in Minneapolis to power small add-on policies sold at checkout. Foundational in London raised £8.2M pre-seed led by Inflection for satellite laser ranging, and Cotierra in Zurich raised $3M for decentralised biochar reactors in Colombian coffee regions.

What unites the stand-outs is a physical or data moat rather than a pure software wrapper around a frontier model: robot training data, military working dogs, laser ground stations, biochar hardware. Investors are increasingly asking seed founders what they own that a model provider cannot replicate in a quarter.

Which exits, IPO filings and acquisitions landed?

Mynt listed in Manila at about $7B, Zetwerk and Jio Platforms closed heavily subscribed Indian offerings, Anthropic’s public S-1 was reported as imminent, and Instacart was reported to have explored a sale.

The week’s most-watched non-event was Anthropic. PYMNTS, citing a Yahoo Finance report from 21 October, said the company could make its IPO paperwork public as early as Friday 23 October, clearing the way for a November listing. As of the weekend no public S-1 had appeared on EDGAR, so the filing remains reported rather than confirmed. Expectations cited in the same coverage are extraordinary, with talk of a raise of up to $100B at valuations between $1.2T and $2T, which would make it the largest venture-backed listing ever and reshape every ranking of the biggest venture-backed exits by year. The same coverage noted softer IPO conditions elsewhere, including Elice’s 32% first-day drop in Korea and Firmus Grid shelving its listing.

Asia delivered the completed exits. Mynt, the GCash parent backed by Globe, Ayala and Ant, debuted on 20 October at its 6.60 peso offer price and closed flat, valuing it at roughly $7B. In India, Zetwerk’s $518M IPO, backed by Peak XV and Accel, was fully subscribed on institutional demand, and Jio Platforms’ $3.2B offering was fully covered within two hours of public bidding, according to DealStreetAsia. Inc42 reported that Mygate will amalgamate with adtech company AdOnMo by 5 December, with Zomato parent Eternal taking a 4.4% stake in the combined entity.

In the US, TechCrunch reported on 24 October that Instacart had discussed selling itself to DoorDash and to Uber, with no deal reached. In Europe, Tech.eu listed Omnidocs acquiring WoodWing, Workflex acquiring rhome and Standard Chartered agreeing to buy Zodia Custody. None of these carried disclosed prices.

Which VC funds closed?

Seaya Nova (€600M first close), Inspired Capital Fund IV ($450M), Vintage Investment Partners ($920M), Inovia Fund VI ($200M first close) and Bison Ventures Fund II ($160M) were the week’s notable fund announcements.

Madrid-based Seaya announced a €600M first close for Seaya Nova on 22 October, a growth fund that will lead or co-lead Series B to D rounds of €20M to €50M in European tech companies, with the European Investment Fund anchoring through the European Tech Champions Initiative. Tech.eu notes the fund was raised in about six months and that Seaya has opened a London office. Two days earlier, on 20 October, Seattle’s Bison Ventures confirmed a $160M Fund II for AI applied to the physical economy, up from a $135M debut, and Canada’s Inovia Capital announced a $200M first close toward a $325M Fund VI focused on AI-native founders in cybersecurity, infrastructure, energy, robotics and quantum.

On 21 October, New York’s Inspired Capital, co-founded by Alexa von Tobel and Penny Pritzker, closed a $450M Fund IV for pre-seed to Series A investments across frontier AI, quantum, defense, fintech and robotics. The same day, Vintage Investment Partners, the Tel Aviv-founded fund-of-funds and secondaries manager, disclosed $920M in new capital, taking firm assets above $4.8B; that is a meaningful liquidity signal for European and Israeli managers whose LPs want secondary exits. DealStreetAsia added OrbiMed’s roughly $1.05B sixth Asia healthcare fund and Pantheon’s $6B global secondaries close, the latter above a $3.5B target with new Asian and Middle Eastern LPs.

These closes land in a fundraising market that remains bifurcated. Established brands and specialist growth vehicles are closing quickly, while first-time managers still take 18 months or more. Our tracker of venture capital funds currently raising in 2026 lists which vehicles are still open, and our guide to the venture capital fundraising process and timeline explains why a first close is announced long before the final one.

What does this week say about the market?

Capital is abundant but concentrated: a handful of AI, defense and biotech names absorbed most of the dollars, Europe showed real depth, and the IPO window is open but selective ahead of Anthropic’s filing.

Three readings stand out. First, the US top ten was roughly $4.3B against about $1.65B the previous week, but that swing is almost entirely two companies. Strip out Tenstorrent and Flapping Airplanes and the remaining eight rounds total about $1.8B, which is close to a normal 2026 week. Headline totals continue to be driven by concentration rather than breadth, a point Crunchbase itself has made repeatedly this year.

Second, Europe is no longer a footnote in these roundups. Three European companies (Legora, Pigment, Blackwall) would have made the US top ten on size, and the Scaleup Europe Fund’s lead in Pigment shows that the continent’s late-stage capital gap is being addressed with structured policy capital rather than hope. Seaya Nova’s €600M first close points the same way. Investors tracking the top venture capital firms in the United States will note that Sequoia, Lightspeed, Accel, Khosla and General Catalyst all appeared as leads in non-US deals this week.

Third, exits are happening, but mostly in Asia and mostly for fintech and manufacturing rather than AI. Mynt, Zetwerk and Jio Platforms are large, profitable or near-profitable businesses. The AI exit story remains hypothetical until Anthropic’s S-1 appears, and the cautionary tales (Elice’s debut, Firmus Grid’s shelved listing) show that public investors are not writing blank cheques. Crunchbase’s 19 October report that LatAm funding jumped 26% in Q3, meanwhile, is a reminder that recovery is spreading beyond the usual hubs even when weekly headlines stay US-centric.

What should founders raising now take from it?

Lead with a defensible asset, expect investors to benchmark you against AI-native peers, use European and Asian growth capital where it fits, and prepare for a longer process if you are not in a favoured sector.

The founders who closed large rounds this week share a trait: each controls something scarce. Tenstorrent has silicon and a famous architect, Flapping Airplanes has a research team investors believe can cut training costs, Xona has orbital assets, Warhound has a biological pipeline and a defense distribution partner, Maxinsights has two million hours of proprietary video. If your pitch is a layer on top of someone else’s model, you will be asked why the model provider will not ship your feature. Have an answer grounded in data, hardware, regulation or distribution.

Geography matters more than it did a year ago. A European Series C founder can now plausibly run a process that includes the Scaleup Europe Fund, Seaya Nova, Atreides and US growth funds in parallel, which improves terms. An Indian founder should note that AI took half of the week’s domestic dollars, and that US firms (Khosla, General Catalyst, Lightspeed, NTTVC) led the three largest rounds. Founders outside these favoured categories should budget for a longer timeline and more meetings, and should treat fund closes such as Inspired Capital’s and Bison’s as a map of who has fresh dry powder for pre-seed and Series A.

Finally, keep an eye on the public market. If Anthropic files and prices well in November, growth-stage valuations for AI infrastructure will reset upward almost immediately; if it stumbles, expect late-stage rounds to slow before the holidays.
