Market Opportunity

The firm’s advisory and capital markets platform is designed to support clients through a broad range of financial and operational inflection points.
According to PwC, global M&A deal values increased 36% between 2024 and 2025, driven in part by a rise in transactions valued at more than $5 billion. PwC reported that megadeals increased from 63 transactions in 2024 to 111 transactions in 2025, while the Americas accounted for approximately 60% of global deal value. The firm also noted that deal values in the Americas increased 55% year over year, reflecting continued activity across the transaction landscape despite broader economic and geopolitical uncertainty. This sustained level of deal activity, alongside generational ownership transitions occurring across the middle market, supports continued demand for the independent advisory and capital markets services Market Street Capital provides.
