A new cast of boutique banks is fuelling a fresh fervour for blank-cheque companies — one of Wall Street’s hottest and most controversial products during the pandemic-era bull market.

Special purpose acquisition vehicles, or Spacs, exploded in popularity during the Covid-19 crisis, with around 600 deals in the US raising a record $163bn in 2021 before the frenzy died down as global stocks tumbled the following year due to rising interest rates. 

But the market has revved up again since Donald Trump won his second term as president, despite volatility sparked by his tariffs delaying several traditional initial public offerings. There have been 44 Spac offerings this year raising $9bn, compared with 57 raising $9.6bn during the whole of 2024, Dealogic data shows.
