Aave accounts for 48% of active loans as DeFi lending surges 30% to $26.1B

DeFi lending just had a very good summer. Total active loans across major decentralized lending protocols climbed to $26.1 billion in August, up from $20.1 billion in June. That’s roughly 30% growth in two months, and Aave is eating nearly half the pie.

The protocol commands approximately $12.5 billion in outstanding loans, good for about 48% of total market share.

The competitive landscape beneath Aave

While Aave towers over the field, the runners-up are putting up respectable numbers of their own. Morpho sits in second place with $5.1 billion in active loans. Spark rounds out the top three at $2.1 billion.

The gap between first and second is telling: Aave holds more than double Morpho’s loan book, and nearly six times Spark’s.

Aave’s growth trajectory in detail

Active loans in July averaged around $10.3 billion, representing roughly a 10% increase from the prior month.

By August, that figure had jumped to $12.5 billion.

On the deposit side, Aave founder Stani Kulechov noted that total deposits crossed the $30 billion mark in August. That represents a 30% increase over the quarter.

Why the lending rebound matters

The broader $26.1 billion figure is significant because DeFi lending had been contracting for several months before this summer’s turnaround. The market went through a period where borrowers pulled back, utilization rates declined, and protocol revenues shrank accordingly.

Most on-chain borrowing is leveraged positioning. Traders deposit ETH or other volatile assets as collateral, borrow stablecoins, and use those stablecoins to buy more crypto.

For Aave specifically, the combination of growing deposits and growing loans translates directly to protocol revenue. Aave collects a spread between borrowing and lending rates, and that spread multiplied by a $12.5 billion loan book generates meaningful cash flow. The protocol’s token economics route a portion of that revenue toward stakers and governance participants.

Morpho’s $5.1 billion position reflects its approach of offering optimized lending rates through peer-to-peer matching, essentially cutting out some of the spread that pool-based protocols like Aave capture.

Spark’s $2.1 billion book is tied closely to the MakerDAO ecosystem, reflecting steady demand for DAI-denominated borrowing.
