The biggest IT funding deals to watch span AI coding, AI infrastructure, cybersecurity and enterprise procurement. This is a curated watchlist of five reported financings selected to show different parts of the technology stack—not a definitive ranking of the world’s largest or most important deals. The examples were reported in July and September 2026, so they are not a same-day snapshot.
Five reported IT funding deals
Each entry separates the reported amount raised from any disclosed valuation and identifies the financing stage or instrument where available. Investor participation offers context, but does not by itself establish a company’s commercial success or technical quality.
| Company | Reported financing | Focus and location | Investors and date |
|---|---|---|---|
| Cognition | Over $2 billion raised; reported valuation of $48 billion. The amount is reported as “over” $2 billion, not as an exact total. | AI coding startup based in New York. | Led by a16z, Accel, Founders Fund, General Catalyst and Avenir. Reported by Axios Pro Rata on September 9, 2026. Axios Pro Rata |
| Celero Communications | $275 million Series C; reported valuation of north of $3 billion. | Digital signal processing technology for AI infrastructure; based in Irvine, California. | Named investors include Atreides Management, Valor Equity Partners, CapitalG, Sutter Hill Ventures and Maverick Silicon. Reported by Axios Pro Rata on September 9, 2026. Axios Pro Rata |
| Cylake | $245 million in convertible notes. This is a financing instrument, not a reported priced equity round or named Series. | Cybersecurity platform focused on operational sovereignty; based in Sunnyvale, California. | Named investors include Lightspeed, Picture Capital and Redpoint Ventures. Reported by Axios Pro Rata on September 9, 2026. Axios Pro Rata |
| ThreatLocker | $190 million Series F. | Cybersecurity. The company said the funding would support AI-related security controls, platform development and international expansion, starting with a U.K. office. | Elephant led, with continued backing from D. E. Shaw Ventures and Arthur Ventures and a new investment from Koch Disruptive Technologies. Reported by Tech Startups on July 29, 2026. The article says ThreatLocker reported protecting more than 70,000 organizations; that is the company’s claim, not an independently audited figure. Tech Startups |
| Freehand | $75 million financing; a Series label was not stated in the cited report. | Enterprise procurement software using autonomous AI agents for supplier, invoice, payment and reconciliation workflows. | Co-led by Battery Ventures and NewRoad Capital Partners, with participation from PSP Growth and Nexus Venture Partners. Reported by Tech Startups on July 29, 2026. Tech Startups |
What the mix of deals shows—and does not show
AI appears across several layers
Cognition applies AI to coding, Celero supplies signal-processing technology for AI infrastructure, and Freehand targets procurement workflows. These are distinct applications, not interchangeable measures of one market. Freehand’s financing, in particular, is one applied-AI example; it does not establish a broad investor preference for procurement software.
Cybersecurity funding has different forms
ThreatLocker’s Series F and Cylake’s convertible notes are not the same type of financing. A convertible note can convert into equity under its terms, so its headline amount should not be treated as a priced equity valuation or given an invented Series designation. The reports do not provide a valuation for either company in these deals.
#1 Best Overall
Deal size is not company value
The amount raised describes financing; valuation is a separate figure. Cognition’s reported valuation is $48 billion alongside funding of over $2 billion, while Celero’s valuation is described only as north of $3 billion alongside a $275 million Series C. The latter wording does not establish an exact valuation.

KPMG Private Enterprise’s Venture Pulse Q1 2026: Global Analysis of Venture Funding uses PitchBook data provided April 15, 2026, with a data cutoff of March 31, 2026. Its global median deal-size chart lists $2.0 million, $5.9 million, $7.0 million and $20.0 million by stage; a separate chart by series lists $0.5 million, $3.0 million, $0.2 million, $14.3 million, $28.6 million, $57.6 million and $143.0 million. The extracted chart information does not reliably preserve which value belongs to each stage or series, so no one figure should be assigned to a named category here. In any case, those early-2026 global medians predate the July and September financings above. Read KPMG’s Venture Pulse Q1 2026 report.
Rank #2
For another dated comparison, Crunchbase News called Fireworks AI’s $1.505 billion Series D at a $17.5 billion valuation the largest round in its U.S. weekly list published July 17, 2026. The same roundup said Spectro Cloud raised more than $100 million in a Series D led by Goldman Sachs Alternatives, bringing its total capital raised to $260 million. These are additional reported deals, not entries in the five-company watchlist above. Read Crunchbase News’s July 17 roundup.

How to read a funding headline
- Check the date and geography. These examples were reported across July and September 2026 and do not describe one synchronized funding cycle. The Crunchbase comparison is specifically a U.S. weekly list.
- Identify the instrument. A Series C, Series F, convertible notes and financing without a stated Series label are materially different descriptions.
- Separate amount from valuation. A large round does not mean the company’s valuation is the same amount, and a reported valuation may be qualified rather than exact.
- Keep claims attributed. For example, ThreatLocker’s reported organization count is its own claim as relayed by Tech Startups.
- Do not infer performance from investors. A list of participating funds identifies financing context, not proof of product quality, market fit or future returns.
