Disclosed round sizes in Houston are heavily skewed: Caturus’ $9.8B round on 2026-05-15 dwarfs the next-largest disclosed amounts, with NextDecade ($3.5B on 2026-06-25) and Rowan Digital Infrastructure ($3.0B on 2026-05-27) still well below that top figure. Below the top tier, the next discloseds fall into a much tighter range of large rounds (e.g., Texas LNG at $500M on 2026-07-13, Kraken Oil & Gas at $400M on 2026-05-11, and Via Renewables at $325M on 2026-05-06). Stage labeling also clusters: “Series Unknown” accounts for 31 of 50 entries, while Seed (9) and Series A/Series B (3 each) form smaller, distinct groups. The list’s timing runs from 2026-04-15 through 2026-08-04 (all 50 rows shown are in 2026), so the most recent set includes Coraa’s $100K on 2026-08-04 alongside larger disclosed deals the same day (Mariana Minerals at $310M on 2026-08-03).

Frequently asked

Which disclosed round is the outlier, and what sits immediately below it in the ranking?

Caturus is the clear outlier at $9.8B (2026-05-15). The very next-largest disclosed amount is $3.5B from NextDecade (2026-06-25), with Rowan Digital Infrastructure at $3.0B (2026-05-27) following right after.

How concentrated are funding sizes above $100M and above $1B in this Houston set?

For disclosed amounts, there are 11 rounds at or above $100M, including Main Street Capital ($1.2B on 2026-06-29) and Texas LNG ($500M on 2026-07-13). At or above $1B there are 5 disclosed rounds, spanning Caturus ($9.8B), NextDecade ($3.5B), Rowan Digital Infrastructure ($3.0B), Solaris Energy Infrastructure ($1.3B on 2026-05-05), and Main Street Capital ($1.2B).

Does the list lean toward any specific stage label, and what does that imply about comparability?

Series Unknown appears 31 times out of 50, versus 9 Seed rounds and 3 each for Series A and Series B. That means many deals—such as Pie (Series Unknown, 2026-08-04, undisclosed) and Centre Technologies (Series Unknown, 2026-06-24, undisclosed)—can’t be directly benchmarked by stage using the label alone.

Are energy or biotech deals more common than other sectors in this Houston feed?

Energy is the most frequent sector (16 appearances) and biotech is also prominent (6). Examples include Caturus (Energy, $9.8B on 2026-05-15) and Via Renewables (Energy, $325M on 2026-05-06), alongside Oorja Bio (Biotechnology, $30M on 2026-05-19) and Goldenrod Therapeutics (Biotechnology, $7M on 2026-06-04).

What does the time window look like from the oldest to newest round shown?

The rounds span from 2026-04-15 (Cadre Energy Solutions, undisclosed) to 2026-08-04 (Coraa at $100K, and EndoQuest Robotics on 2026-08-04 with undisclosed amount). All 50 rows shown are within 2026, with the newest day containing both smaller disclosed rounds and larger disclosed deals across different sectors.
