American companies are buying each other at a pace that hasn’t been seen before. US M&A deal value hit $1.89 trillion over the trailing four quarters, a record that nearly triples the levels recorded back in Q2 2023.

The numbers behind the boom

The rebound is especially striking when measured against the dealmaking drought of 2023. By Q2 of that year, M&A activity had cratered. Fast forward to now, and the trailing four-quarter total has roughly tripled from that trough.

Globally, the picture looks similar. LSEG data showed a 30% year-over-year increase in M&A value for the first half of 2025, confirming this isn’t just an American phenomenon.

Here’s the wrinkle, though. While aggregate deal value is at record highs, deal count is actually down about 11% year-over-year. In English: fewer deals are getting done, but each one is significantly larger. The megadeals are back.

What’s fueling the fire

Several forces converged to produce this record. The most obvious is the stabilization of borrowing costs. After years of rate hikes that made leveraged buyouts and debt-financed acquisitions painfully expensive, the financing environment has loosened enough for dealmakers to sharpen their pencils again.

The decline in deal count despite record value also suggests that regulatory scrutiny may still be filtering out smaller or more speculative transactions. Antitrust reviews remain a factor, even if the overall appetite for dealmaking has clearly returned.

What this means for investors and crypto

For crypto investors, the connection is less direct but increasingly relevant. As traditional finance undergoes this wave of consolidation, the infrastructure for bridging TradFi and digital assets becomes a logical acquisition target. Companies with blockchain-based settlement technology, tokenization platforms, or compliant crypto custody solutions sit squarely in the sightline of larger financial institutions looking to modernize through acquisition rather than internal development.

The fact that this M&A boom hasn’t yet intersected meaningfully with crypto-native companies is itself a signal. It suggests the space is still early enough that major acquirers haven’t moved in force, but late enough that the capabilities being built are genuinely useful to traditional financial players.

There’s a risk angle here too. Record deal values driven by fewer, larger transactions mean concentration risk is rising. The 11% decline in deal count suggests the market is already somewhat top-heavy.
