Biggest US Funding Rounds This Week: Modal's $750M Leads

Crunchbase's weekly ranking found just two U.S. rounds at or above $200M this week -- Modal Labs' $750M Series D and Icon's $200M Series D -- with investors otherwise sticking to the $60M-to-$135M range across AI, biotech and construction tech.

THE RUNDOWN

1

Only two of this week's ten biggest U.S. rounds reached $200M or more -- Modal Labs' $750M Series D and Icon's $200M Series D -- a thinner mega-round crop than recent weeks.

2

Seven of the ten rounds went to AI-adjacent or healthtech companies, reinforcing which sectors are still commanding premium checks.

3

The $60M-to-$135M cluster, including North.cloud, Mueon, Stand and Souffle Therapeutics, shows where most 'big' rounds actually land once the outliers are excluded.

Crunchbase notes deal activity held steady -- it's specifically the very largest checks that thinned out, not the overall pace of financing.

A week with no $300M-plus round is a useful tell. It's not a sign the AI funding boom is over -- Modal alone still raised $750M -- but it's a reminder that the mega-round pace of the past few months was never guaranteed to be a steady cadence. GPs should track this weekly list for three or four consecutive weeks before reading anything into a single quiet one.

Analysis

Crunchbase's weekly tally of the biggest U.S. funding rounds, covering October 10-16, found a noticeably thinner crop of mega-deals than recent weeks, with investors sticking closer to the middle of the pack than the very top. The full ranking put AI infrastructure and healthtech back atop the list:

  • Modal Labs -- $750M Series D (led by Accel, at a $15.75B valuation): AI cloud infrastructure for running GPU workloads.
  • Icon -- $200M Series D (co-led by Baillie Gifford and BlackRock): robotic 3D-printed construction technology.
  • Souffle Therapeutics -- $135M Series B (led by Juvia Group, part of a larger syndicate): RNA-based therapies.
  • Estuary Biotherapeutics -- $103M total ($93M Series A led by RA Capital Management plus an earlier $10M seed): gene therapies for ADPKD, a common inherited kidney disease.
  • Labelbox -- $100M+ Series E (led by Infinitum Partners): data-labeling and reinforcement-learning infrastructure for frontier AI models.
  • Suki -- $90M Series E (backers include Healthier Capital and Crosslink Capital, no single lead named): AI voice assistant for clinicians.
  • Abby Care -- $82M Series C (led by Transformation Capital): platform paying family members as caregivers.
  • Stand -- $70M Series C (led by Saga Ventures, at a $1B valuation): insurance technology for homes exposed to natural disasters.

“- Modal Labs -- $750M Series D (led by Accel, at a $15.75B valuation): AI cloud infrastructure for running GPU workloads.”

Crunchbase's framing is that investors 'scaled back on giant rounds' this week, with only two financings in the hundreds of millions compared to a steadier run of $200M-plus deals in prior weeks. However, the outlet is careful to note this isn't a broad pullback -- deal volume held roughly flat, and most of this week's checks still landed in healthy nine-figure territory. What thinned out was specifically the very top of the distribution, the handful of $300M-plus rounds that had become almost routine earlier in the AI funding cycle.
