This is a monthly feature that runs down the month鈥檚 top 10 funding rounds in the U.S. Check out last month鈥檚 edition here.

September saw a couple of $1 billion rounds lead the way. However, the rounds were smaller in October, as cleantech and energy saw big raises but not at the billion-dollar level. Just like September, however, biotech played a starring role as investors kept the faith despite the sector鈥檚 typically long product development cycle.

Here鈥檚 a quick review of the top 10 rounds of October:

1. , $500M, cleantech: Cleantech continues to hold investor interest, especially cleantech companies that deal in carbon. Illinois-based carbon recycler LanzaTech locked up the biggest round last month, closing a $500 million commitment from to finance upcoming projects using its technology. The deal size could double if certain milestones are met. The company鈥檚 tech takes the carbon out of emissions and converts it into things such as sustainable fuels and material. Founded in 2005, the company has now raised more than $800 million, according to SA国际传媒 data.

2. , $450M, energy: One of the biggest problems with wind and solar energy is that both are intermittent, and lithium-ion batteries can only store energy for so long. Enter iron-air batteries, which can store energy longer and promise to be cheaper. That obviously is what is betting on, as it was the lead investor in a new $450 million round for Massachusetts-based Form Energy. The round also included investments from others, such as 鈥� . The 5-year-old startup plans to use the new funding to build a manufacturing facility for its batteries and ramp up production. Founded in 2017, the company has raised nearly $820 million, according to SA国际传媒.

3. , $401M, cybersecurity: Convertible notes could become more en vogue as the venture capital pullback continues. Last month, Eden Prairie, Minnesota-based Arctic Wolf went that route. The managed security provider raised $401 million in convertible notes led by existing investor . Convertible notes work like a short-term loan, but these notes are repaid to the investor at a later point in equity 鈥� i.e. after an IPO 鈥� typically at a discount, and can also include an interest rate. Arctic Wolf raised $150 million in a Series F in July 2021, taking the company鈥檚 valuation from $1.3 billion to $4.3 billion. At that time, then-CEO an IPO was likely the next logical move. However, that was a much different time. Founded in 2012, Arctic Wolf has raised nearly $900 million, according to SA国际传媒 data.

4. , $400M, media: Private equity giant must have liked 鈥淭op Gun: Maverick.鈥� The PE firm made a big $400 million last month in Skydance, the production house behind the summer blockbuster.

Then just last week, the startup closed a $200 million Series C led by Fifth Wall Climate, which also included a $100 million debt facility. That鈥檚 a lot of cash in a month.
