Oaktree Capital Management, an asset manager, has closed its eleventh opportunities fund on $16 billion, marking the firm's largest vehicle yet and continuing a steady stream of mega-funds from asset managers and private equity firms.

Oaktree, owned by parent company Brookfield Asset Management, has invested in various industries including crude petroleum, natural gas, coal, consumable fuels and environmental facilities services.

The $16 billion close by Los Angeles-based Oaktree adds to an active November for mega-funds—defined as a vehicle that has raised over $5 billion.

On Nov. 15, The Carlyle Group announced it was targeting between $8 billion and $10 billion for its sixth flagship Asia-focused fund. A few days earlier, HPS Investment Partners said it was seeking $9.5 billion for its fifth junior debt fund.

General Atlantic announced it had closed its sixth flagship fund on $7.8 billion Nov. 10, and EQT said it had raised €15.7 billion (about $17.7 billion) for its fifth infrastructure fund Nov. 2.

Oaktree closed its 10th opportunities fund on $3.6 billion in 2016.
