- Private equity backs (Green Line) has grown by more than 475%.
This indicates that there is no shortage of entrepreneurs and ideas in the US.

The public market supports household wealth, innovation and economic growth
Certainly, the private and public markets work together.
While the private market often offers the flexibility that early stages and high-growth companies need to scale, the open market offers a well-defined regulatory and liquidity framework that reduces capital costs and promotes accountability beneficial to the broader society.
Still, as highlighted in Nasdaq’s New, there are challenges created by this trend of more companies staying private. White Paper:

Make the public markets attractive again
As the public market plays a key role in economic growth, employment, R&D and household wealth, it is important to address the issues that contribute to the decline of the public market.
A recent NASDAQ whitepaper highlighted some common-sense reforms that could help reinvigorate the public markets and, ultimately, the US economy.
These include:
- Reduce the burden of regulations Expand disclosure requirements to the size of the company, as adopted in the UK, and publish by simplifying quarterly reports or providing six-month reports.
- Modernizing proxy voting Processes such as streamlining communications with shareholders, raising ownership thresholds to submit proposals, and the level of shareholder support required to resubmit proposals.

Revitalizing the open market will help unlock a stronger American economy
These structural changes will help create economics that will strengthen the US open market and encourage more companies to continue to be public.
Over time, the US stock market will play an even more important role in supporting economic progress and economic security for everyone.
