Across these 50 most recent San Diego funding rounds, the largest disclosed amount is Ligand Pharmaceuticals’ $625M (2026-06-23), which dwarfs the next-highest disclosed amounts (e.g., Maxwell Power’s $750M is actually larger, and is the true maximum). In fact, Maxwell Power’s $750M (2026-06-01) is the only disclosed round at that scale, while most other disclosed rounds cluster far below it (many sit between $20M and $150M). The list also shows temporal clustering: multiple rounds land in a tight late-June window (e.g., 2026-06-17 to 2026-06-25 includes Lycia Therapeutics $75M on 2026-06-25; Aether AI $20M on 2026-06-17; and Replicate Bioscience $3M on 2026-06-19). Sector-wise, Biotechnology is the most frequent category (appearing in 16 of 50 rows), and “Series Unknown” is common (12 of 50 rows), alongside undisclosed amounts in 8 of 50 rows. Disclosed amounts range down to $10K (Finlete on 2026-06-05 and also Magier AI $30K; the minimum disclosed value appears with Finlete), indicating sharp dispersion even within a single geography. Dates span from 2026-03-24 (Rybodyn, $10M) to 2026-06-25 (Lycia Therapeutics).

Frequently asked
What’s the biggest disclosed round in this San Diego list, and how does it compare to the rest?
Maxwell Power’s $750M on 2026-06-01 is the dominant disclosed outlier in this set. The next-largest disclosed amounts are still very large (e.g., Mirum Pharmaceuticals’ $600M on 2026-05-12 and Ligand Pharmaceuticals’ $625M on 2026-06-23), but the $750M level sits above all other disclosed entries shown here.
Do the most recent rounds cluster into a narrow time window?
Yes. Late June is dense: between 2026-06-17 and 2026-06-25 there are multiple rounds including Aether AI ($20M, 2026-06-17), Swastham.ai ($280K, 2026-06-11), and Lycia Therapeutics ($75M, 2026-06-25). The earliest dated row shown is 2026-03-24 (Rybodyn, $10M), so the recency bias is clear across the full span.
Which sectors show the strongest concentration, and which appear only occasionally?
Biotechnology leads with 16 of 50 rows (e.g., Lycia Therapeutics $75M on 2026-06-25; ClearNote Health $52M on 2026-05-27; Neomorph $100M on 2026-04-13). Other sectors occur far less often: for example, Energy appears in 6 of 50 rows (Maxwell Power $750M on 2026-06-01; Pathway Power $150M on 2026-06-05), while Manufacturing appears in 1 of 50 rows (Syntec Optics $20M on 2026-04-29).
How much of the stage and deal sizing is hard to benchmark due to ‘Series Unknown’ or undisclosed amounts?
Stage labeling is frequently missing: “Series Unknown” appears in 12 of 50 rows (e.g., Ligand Pharmaceuticals $625M on 2026-06-23 and Innovative Industrial Properties $350M on 2026-06-10). Amount disclosure is also incomplete: 8 of 50 rows list “undisclosed” amounts (e.g., Endure Biotherapeutics on 2026-06-22 and Element Biosciences on 2026-06-09), which makes comparisons to disclosed peers less direct for those deals.
Are there unusually small or unusually large disclosed rounds beyond the top end?
On the low end, the smallest disclosed amount shown is $10K for Finlete on 2026-06-05, contrasting with many other disclosed deals that fall into much higher bands (e.g., Green Pace Financial $86M on 2026-06-01 and EDGE Markets $29M on 2026-06-08). On the high end, the top cluster includes Maxwell Power $750M (2026-06-01) and Mirum Pharmaceuticals $600M (2026-05-12), suggesting a wide dispersion in capital raised even within the same city.
