AI funding tracker: major rounds 2024 to 2026
A reference of the rounds that built the bubble, with sources cited where each number came from
What this tracker covers and what it does not
Foundation-model labs: the top of the stack
These are the companies building general-purpose frontier models. Five players dominate the round-size league table. As of early 2026, OpenAI and Anthropic alone account for more committed primary capital than every other AI company combined.
What the foundation-lab numbers actually mean
Infrastructure and inference: the picks and shovels
Three companies stand out in the AI infrastructure layer for non-public capital activity: Cerebras went all the way to an IPO, Groq pivoted toward Gulf-state infrastructure financing, and Together.ai is positioning as the open-source-first inference cloud.
Cerebras Systems
IPO May 2026 · approx $40B implied
Wafer-scale AI accelerator company. Raised $1.1B at an $8.1B valuation in September 2025, then $1B at $23B in February 2026, then priced an IPO in May 2026 at $185 per share with an implied market cap of approximately $40B (roughly $99B fully diluted). Revenue scaled from $24.6M in 2022 to $510M in 2025 per the S-1 disclosure.
Groq
Sep 2025 · $6.9B
Inference-only chip company built around its LPU architecture. Series D in August 2024: $640M at $2.8B post-money, led by BlackRock with Cisco, KDDI, Samsung Catalyst, Neuberger Berman. September 2025 follow-on: $750M at approx $6.9B post-money. Plus a $1.5B commitment from Saudi Arabia in February 2025 to fund a Dammam data center, structured as infrastructure commitment, not pure equity.
Together.ai
Feb 2025 · $3.3B
Open-source-first AI cloud and inference platform. Series B in February 2025: $305M, General Catalyst and Prosperity7 co-led, Salesforce Ventures, Nvidia, Kleiner Perkins, Coatue participating. $3.3B post-money, up from a reported $1.25B the prior year.
Hugging Face
Aug 2023 · $4.5B
Model hub and open-source community platform. Series D in August 2023: $235M at $4.5B post-money. Investors included Google, Amazon, Nvidia, Intel, AMD, Qualcomm, IBM, Salesforce, Sound Ventures. Reported FY2024 revenue approximately $130M per third-party trackers. No publicly confirmed primary round in 2024 or 2025 at the time of writing.
Magic
Aug 2024 · approx $1.5B reported
AI-coding lab building a long-context coding model. August 2024: $320M, led by Eric Schmidt and Alphabet's CapitalG, with Atlassian, Sequoia, Elad Gil, Jane Street, Nat Friedman and Daniel Gross. Total funding to date approximately $465M. Specific post-money valuation for the August round was not publicly disclosed; prior reporting (Reuters) indicated a target above $1.5B.
Enterprise AI applications: tools sold into the Fortune 500
These are the AI-native application companies selling primarily into enterprise IT, legal, finance, and knowledge-work organizations. The unit-economic story here is healthier than at the model-lab layer: most of these companies cite real ARR figures (Glean over $100M, Harvey targeting $100M, Writer with strong Fortune 500 logos).
Media generation: video, voice, music, image
The creative-tool layer. The interesting structural fact here is that one of the largest and most profitable companies in the cohort, Midjourney, has taken zero venture capital. Two companies in the cohort (Suno, Udio) face active litigation from major record labels.
Runway
Apr 2025 · $3B
AI video generation. Series D in April 2025: $308M, General Atlantic led, with Nvidia, SoftBank, Fidelity, Baillie Gifford. $3B post-money, up from a previous $1.5B. Later reporting indicates a Series E at approx $5.3B.
Synthesia
Jan 2025 · $2.1B
Enterprise AI avatar video. Series D in January 2025: $180M, NEA led, with GV, MMC, FirstMark, WiL, Atlassian Ventures, PSP Growth. $2.1B post-money. Later $200M Series E in January 2026 led by GV with Nvidia NVentures at $4B post.
ElevenLabs
Jan 2025 · $3.3B
AI voice generation. Series C in January 2025: $180M, a16z and ICONIQ Growth co-led, with NEA, WiL, Valor, Endeavor Catalyst, Lunate. $3.3B post-money. Subsequent February 2026 round: $500M at $11B, Sequoia led, per CNBC and TechCrunch.
Pika Labs
Jan 2024 · approx $530M
AI video generation. Series A in January 2024: approx $80M, Lightspeed led, with Spark Capital and angel investors including Andrej Karpathy and Elad Gil. Approximately $530M valuation reported. A subsequent Series B in 2024 added approximately $80M more.
Suno
Late 2025 · $2.45B
AI music generation. Series B in May 2024: $125M, Lightspeed led, with Nat Friedman, Daniel Gross, Matrix, Founder Collective. $500M post-money reported. Series C in late 2025 at $2.45B post-money on approximately $200M in revenue per TechCrunch. Suno faces active litigation from the major US record labels.
Udio
Apr 2024 · undisclosed post
AI music generation, founded by ex-DeepMind researchers. Seed round of $10M announced April 2024, a16z led, with will.i.am, Common, UnitedMasters, Mike Krieger. Like Suno, Udio is subject to major-label copyright litigation.
Midjourney
No VC · approx $300M 2024 revenue
AI image generation. Bootstrapped. Zero outside venture capital. Cited as profitable since the first months of 2022. Multiple third-party trackers put 2024 revenue in the $200M to $300M range; one tracker cites $500M ARR by 2025 and an internal valuation of approximately $10B. Treat the implied-valuation figures as third-party estimates, not official disclosures.
Stability AI
Jun 2024 · rescue round
Maker of Stable Diffusion. June 2024 rescue financing of approximately $80M, led by an investor group including Sean Parker (as executive chairman), Greycroft, Coatue, Sound Ventures, Lightspeed, O'Shaughnessy Ventures, Eric Schmidt, and others. CEO Emad Mostaque had departed in March 2024 amid an investor-mutiny situation; Prem Akkaraju took over as CEO. Valuation not officially disclosed but widely reported as well below the previously cited $1B mark.
The reverse acqui-hires: when a buyout looks like a license
A new deal structure took shape in 2024: Big Tech hires the founders, licenses the technology, and pays investors back, without filing for a formal acquisition. Three of these landed inside a four-month window and triggered active FTC and CMA inquiries. Pull these out separately because the cap-table consequences look nothing like a normal round.
Mar 2024
Microsoft - Inflection AI
Microsoft hired Mustafa Suleyman (Inflection CEO, ex-DeepMind co-founder) and most of the senior team to lead the newly formed Microsoft AI consumer division. Microsoft paid Inflection approximately $650M in licensing fees. Inflection had previously raised approximately $1.525B at a $4B valuation in June 2023. The licensing payment was structured to make Inflection investors close to whole. The FTC opened an inquiry into whether the structure was designed to evade an acquisition review.
Jun 2024
Amazon - Adept
Amazon hired Adept CEO David Luan (ex-OpenAI VP Engineering) plus co-founders Augustus Odena, Maxwell Nye, Erich Elsen, Kelsey Szot, and other employees to Amazon's AGI team. Amazon took a non-exclusive license to Adept's technology. Adept had raised approximately $415M total, including a $350M Series B in March 2023 at over $1B valuation. Adept continued nominally as an independent company with a remaining team. FTC inquired.
Aug 2024
Google - Character.AI
Google paid approximately $2.7B for a non-exclusive license to Character.AI's technology and the rehire of co-founders Noam Shazeer and Daniel De Freitas, plus key researchers. Shazeer had previously worked at Google and left in 2021. Character.AI had been valued at $1B in 2023. The Department of Justice opened an inquiry into whether the structure circumvented antitrust review. This is the deal that crystallized the pattern.
The meta-observation: what shape this funding cycle actually has
Most of the public commentary on the 2024-2026 AI funding cycle reaches for the word "bubble" without specifying what kind of bubble. There are at least three distinct shapes layered on top of each other, and they have different risks. The first shape is hyperscaler-driven capex into AI infrastructure. Big Five hyperscaler capex is on track for over $600B in 2026 per multiple industry trackers, roughly 75% of which is AI-related. This is being financed with a mix of operating cash flow, free-cash-flow contraction (Strategas estimates a 16%+ FCF shrink at the hyperscalers over the next 12 months), and roughly $108B of debt issued in 2025 alone with projections of approximately $1.5T over the coming years. This is a balance-sheet bet, not a venture bet. If frontier model demand stalls, the public-market hit lands on Amazon, Microsoft, Google, Meta, and Oracle first. The second shape is private-market concentration into the top five labs. Nearly two-thirds of US venture deal value went to AI in H1 2025, up from 23% in 2023, with most of that flowing to a handful of names. OpenAI plus Anthropic alone now account for more committed primary capital than the rest of the AI cohort combined. The Bank of America Global Fund Manager Survey in late 2025 was the first in two decades to show a majority of fund managers worrying that companies are overspending. That is a sentiment indicator, not a fundamental one, but it is a meaningful regime shift. The third shape is circular financing among the largest players. Nvidia invests in OpenAI; OpenAI commits to Nvidia compute purchases; Microsoft invests in OpenAI; OpenAI uses Microsoft Azure; Amazon invests in Anthropic; Anthropic runs on AWS. The cash flows back to the strategic investor. This is not new (telecom did versions of it in the late 1990s), and it is not inherently a fraud signal. But it means traditional revenue-quality analysis is hard, because so much of the customer base is also the funding base. None of this implies a crash. It does imply that the shape of the cycle is being driven by capital allocation at the very top of the stack, not by bottom-up product unit-economics at the application layer. Treat the round sizes accordingly.
What to watch through the rest of 2026
A short list of the verifiable forward indicators that will tell you which way this cycle resolves. None of these are predictions. They are the tape to watch.
- Hyperscaler free cash flow trajectory through 2026 reported earnings. Strategas projected over 16% FCF contraction; the actual prints will say whether AI capex is being financed through operating cash or through debt.
- OpenAI primary-market markup velocity. The cadence of $157B (Oct 2024) to $300B (Mar 2025) to $852B (Mar 2026) cannot continue indefinitely without an IPO or a structural change.
- Cerebras post-IPO trading. The first publicly traded pure-play AI infrastructure name (post-IPO May 2026 at approximately $40B implied) becomes the price-discovery instrument for the rest of the chip cohort.
- Court resolution on Suno and Udio. The major-label suits filed in 2024 are the cleanest copyright test cases for generative media. A ruling either way reshapes the music-generation funding thesis.
- Regulatory resolution on the reverse acqui-hires. FTC, DOJ, and CMA inquiries on Microsoft-Inflection, Amazon-Adept, and Google-Character.AI are open as of writing. A consent decree or a forced unwind would change the structure of future Big Tech minority deals.
- Anthropic / Google milestone tranches. The reported $30B contingent on milestones inside the up-to-$40B Google commitment is one of the cleanest publicly visible cases of contingent strategic AI capital. The tranche releases will be readable as a signal of Anthropic performance.
- Sovereign wealth participation share. MGX (UAE), the Saudi PIF, Qatar Investment Authority, GIC (Singapore), and Mubadala have appeared as anchor or co-lead investors in xAI, OpenAI, Anthropic, Mistral, and Groq. Their share of the next round of marquee deals will tell you how Gulf and East Asian sovereign capital is sizing the AI trade.
- Enterprise revenue at the application layer. Glean over $100M ARR, Harvey targeting $100M, ElevenLabs over $330M, Writer with Fortune 100 logos. The application-layer companies are the only part of the cohort with a SaaS-style revenue ramp visible from the outside. Watch their net retention numbers.
