02 Monthly totals swing on a few closings

March looked like a record month. It was the month OpenAI closed. Take out the $1B rounds and every month looks much like the last.

03 Two names at the top

Read the totals with the big rounds taken out

When a headline says funding rose or fell, check whether a $10B round closed that month. For the market most founders raise in, watch the total without $1B rounds and the median round. Both barely moved.

How this was measured Show
  • 9,849 venture equity rounds announced between 1 October 2025 and 30 September 2026, of which 7,984 disclosed an amount. Counted by announcement date, and only rounds we serve through the API.
  • Venture equity means rounds into private companies. Debt, convertible notes, grants, PIPEs, secondaries, pre-IPO and private equity rounds are left out, and so are raises by listed companies.
  • One raise counts once, however many publications covered it. Amounts are converted to USD at the rate on the announcement date.
  • Every round over $1B gets reported. Small rounds often do not, so the true total under $10M is higher than shown here. Doubling it would still leave rounds of $1B or more with more than half of the money.
  • Round counts rose late in the window as our coverage widened, so this report compares money and medians rather than counts.
