Public market statistics at a glance
Public market statistics show a market that is still large, still global, and still changing shape. The headline numbers point to a world with roughly 44,000 listed companies, $125 trillion in global listed-company market capitalization, and a public-equity base that remains heavily concentrated in a few markets (OECD Corporate Governance Factbook 2025).

Public market size and concentration
The most important public market statistics are not just the raw counts. They show how ownership, listings, and market value are distributed across regions and exchanges.
Key takeaway: the public market is broad in company count but far more concentrated in market value.
At the end of 2024, the OECD said the United States accounted for half of global listed-company market capitalization (OECD Corporate Governance Factbook 2025). That means a relatively small number of markets still carry a disproportionate share of global listed equity value.
The same OECD dataset shows that Asia accounted for 58% of listed companies while holding 27% of market capitalization (OECD Corporate Governance Factbook 2025). That gap matters because it suggests many Asian listings are smaller on average than the global value share implies. Europe, meanwhile, held nearly 6,500 listed companies and 13% of market capitalization (OECD Corporate Governance Factbook 2025), reinforcing the same point: company counts do not translate evenly into value.
At-a-glance market concentration
| Region or market | Listed companies | Market capitalization | Source |
|---|---|---|---|
| United States | Half of global listed-company market cap | Half of global listed-company market cap | OECD Corporate Governance Factbook 2025 |
| Asia | 58% of listed companies | 27% of global market cap | OECD Corporate Governance Factbook 2025 |
| Europe | Nearly 6,500 listed companies | 13% of global market cap | OECD Corporate Governance Factbook 2025 |
| Worldwide | About 44,000 listed companies | USD 125 trillion | OECD Corporate Governance Factbook 2025 |
This kind of split is why public market statistics are useful for more than market-size trivia. They show where capital formation is happening, where investor attention is concentrated, and how diversified the listed universe really is.
IPO and listings activity
IPO statistics reveal the pace at which new companies enter public markets. The SEC figures in the dataset show a market that accelerated from 2024 into 2025 on both count and proceeds.
IPO count trends
In 2024, SEC IPOs totaled 246 (SEC IPOs). In 2025, IPOs totaled 374, with quarterly counts of 84, 96, 111, and 83 (SEC IPOs). That is a clear increase in issuance volume, and the quarterly pattern shows the strongest activity in the third quarter.
Breakdown by issuer type adds another layer:
- U.S. issuers: 140 IPOs in 2024 and 227 in 2025 (SEC IPOs).
- Non-U.S. issuers: 106 IPOs in 2024 and 147 in 2025 (SEC IPOs).
- Corporate issuers: 186 IPOs in 2024 and 226 in 2025 (SEC IPOs).
- Blank check/SPAC issuers: 58 IPOs in 2024 and 144 in 2025 (SEC IPOs).
- Fund issuers: 2 IPOs in 2024 and 4 in 2025 (SEC IPOs).
IPO count and proceeds table
| Metric | 2024 | 2025 | Source |
|---|---|---|---|
| Total IPOs | 246 | 374 | SEC IPOs |
| U.S. issuer IPOs | 140 | 227 | SEC IPOs |
| Non-U.S. issuer IPOs | 106 | 147 | SEC IPOs |
| Corporate issuer IPOs | 186 | 226 | SEC IPOs |
| Blank check/SPAC IPOs | 58 | 144 | SEC IPOs |
| Fund issuer IPOs | 2 | 4 | SEC IPOs |
| Total IPO proceeds | $39,212.6 million | $70,130.8 million | SEC IPOs |
| Average IPO proceeds | $159.4 million | $187.5 million | SEC IPOs |
| Median IPO proceeds | $53.6 million | $105.3 million | SEC IPOs |
The money raised also moved higher. Total IPO proceeds were $39,212.6 million in 2024 and $70,130.8 million in 2025 (SEC IPOs). Average proceeds rose from $159.4 million to $187.5 million, while median proceeds rose from $53.6 million to $105.3 million (SEC IPOs). That median jump is notable because it suggests the typical deal size increased materially, not just the very largest offerings.
The issuer-type proceeds data points to different capital-raising profiles:
- U.S. issuer IPO proceeds: $32,473.2 million in 2024 and $60,925.5 million in 2025 (SEC IPOs).
- Non-U.S. issuer IPO proceeds: $6,739.4 million in 2024 and $9,205.3 million in 2025 (SEC IPOs).
- Corporate IPO proceeds: $30,412.8 million in 2024 and $43,222.1 million in 2025 (SEC IPOs).
- Blank check/SPAC IPO proceeds: $8,669.2 million in 2024 and $26,792.0 million in 2025 (SEC IPOs).
- Fund IPO proceeds: $130.6 million in 2024 and $116.7 million in 2025 (SEC IPOs).
Why IPO proceeds matter
The volume of IPOs tells you how many businesses are coming public. Proceeds tell you how much capital the market is allocating to those entrances. When both counts and dollar totals rise together, the message is not subtle: public market issuance is not only more frequent, it is also more capital-intensive.
Exchange-by-exchange market data
Public market statistics become more useful when you look at individual exchange operators. The dataset includes SEC, Nasdaq, ICE, FESE, WFE, and TWSE figures that help show scale in different corners of the market.
Nasdaq and NYSE
Nasdaq reported 5,249 companies listed securities across its U.S., Nordic, Baltic, and First North exchanges as of December 31, 2024 (Nasdaq 2024 10-K). It also reported 4,075 total listings on The Nasdaq Stock Market as of that date (Nasdaq 2024 10-K).
Within that U.S. market, Nasdaq said:
- 1,383 listings were on the Nasdaq Global Select Market (Nasdaq 2024 10-K).
- 1,366 listings were on the Nasdaq Global Market (Nasdaq 2024 10-K).
- 1,326 listings were on the Nasdaq Capital Market (Nasdaq 2024 10-K).
Nasdaq also said the combined U.S. market capitalization of its listed securities was about $34.4 trillion as of December 31, 2024, while its European listed companies represented about $2.0 trillion in market capitalization (Nasdaq 2024 10-K).
ICE said more than 70% of S&P 500 companies were listed on the NYSE as of December 31, 2024 (ICE 2024 10-K). It also said NYSE had 75% of ETF AUM, or roughly $7.8 trillion (ICE 2024 10-K).
That same ICE filing gives useful activity metrics:
- NYSE cash handled volume was 2,436 million shares in 2024 versus 2,231 million in 2023 (ICE 2024 10-K).
- NYSE cash market share matched was 19.7% in 2024 versus 19.9% in 2023 (ICE 2024 10-K).
- NYSE equity options volume averaged 9,375 thousand contracts in 2024 versus 7,900 thousand in 2023 (ICE 2024 10-K).
- Total equity options volume averaged 44,360 thousand contracts in 2024 versus 40,369 thousand in 2023 (ICE 2024 10-K).
- NYSE share of total equity options was 21.1% in 2024 versus 19.6% in 2023 (ICE 2024 10-K).
Other major market snapshots
FESE said listed companies on member markets reached nearly 7,200 on average in 2024, and listed-company market capitalization reached €14.1 trillion at the end of December 2024 (FESE Annual Statistical Report 2024). It also said there were 219 listings in 2024 raising €61.1 billion, with about half of those listings being IPOs (FESE Annual Statistical Report 2024).
WFE said its equity markets covered 53,601 listed companies in December 2024, with market capitalization of $120,809,774.84 million and value of share trading of $14,431,297.26 million (WFE Dashboard: December 2024). It also reported 5,094,832.62 thousand trades, $51,739.52 million in investment flows, 15,308,434,886 options contracts traded, and 2,606,187,182 futures contracts traded in December 2024 (WFE Dashboard: December 2024).
TWSE said it had 1,031 listed stock companies at end-2024, including 37 newly listed stock companies, 174 listed ETFs, and 35,777 listed warrants (TWSE 2024 Market Highlights). TWSE also reported market capitalization of NTD 73,898,668 million and a market capitalization-to-GDP ratio of 289.23% at end-2024 (TWSE 2024 Market Highlights).

These figures are not directly comparable line by line, because each organization measures a different perimeter. But they are still useful together because they show the depth of public-market infrastructure and the scale of the listed ecosystem.
Retail, household, and institutional ownership
Public market statistics are not just about companies and exchanges. They also describe who owns the market.
The ICI said worldwide regulated open-end fund assets reached $68.9 trillion in 2023, with $33.6 trillion in the United States, $21.5 trillion in Europe, $9.7 trillion in Asia-Pacific, and $4.0 trillion in the rest of the world (ICI 2024 Fact Book Quick Facts). It also said U.S.-registered investment company net assets were $33.9 trillion in 2023 (ICI 2024 Fact Book Quick Facts).
Household participation
The household-side numbers are especially important:
- 71.5 million US households owned funds in 2023 (ICI 2024 Fact Book Quick Facts).
- 54.4% of US households owned funds in 2023 (ICI 2024 Fact Book Quick Facts).
- 74% of households had tax-advantaged retirement savings in 2023 (ICI 2024 Fact Book Quick Facts).
- The US retirement market totaled $38.4 trillion in 2023 (ICI 2024 Fact Book Quick Facts).
- DC plan and IRA assets invested in mutual funds totaled $11.9 trillion in 2023 (ICI 2024 Fact Book Quick Facts).
Those figures show why public markets matter to ordinary savers. They sit inside retirement portfolios, mutual funds, ETFs, and long-term savings vehicles that touch tens of millions of households.
Fund and ownership split table
| Metric | Figure | Source |
|---|---|---|
| Worldwide regulated open-end fund assets | $68.9 trillion | ICI 2024 Fact Book Quick Facts |
| US-registered investment company net assets | $33.9 trillion | ICI 2024 Fact Book Quick Facts |
| Mutual funds within US-registered investment company net assets | $25.5 trillion | ICI 2024 Fact Book Quick Facts |
| ETFs within US-registered investment company net assets | $8.1 trillion | ICI 2024 Fact Book Quick Facts |
| US households owning funds | 71.5 million | ICI 2024 Fact Book Quick Facts |
| US households owning funds | 54.4% | ICI 2024 FactBook Quick Facts |
| US retirement market | $38.4 trillion | ICI 2024 Fact Book Quick Facts |
| DC plan and IRA assets in mutual funds | $11.9 trillion | ICI 2024 Fact Book Quick Facts |
Institutional ownership is just as striking. OECD said institutional investors held 47% of total global equity holdings at the end of 2024 (OECD Corporate Governance Factbook 2025). In the United States, they held 69% of listed equity at the end of 2024 (OECD Corporate Governance Factbook 2025).
That gap between household participation and institutional control helps explain why public markets can feel both broad and concentrated at the same time. Many households participate indirectly through funds and retirement accounts, while large institutions still own a dominant share of listed equity.
What the public market statistics suggest
The data points in this topic line up around a few clear themes.
1. The public market is huge, but value is concentrated
With roughly 44,000 listed companies and $125 trillion in global market capitalization, the public market is vast (OECD Corporate Governance Factbook 2025). But the distribution is uneven. The United States accounts for half of global listed-company market capitalization, while Asia holds 58% of the listed companies and only 27% of the market value (OECD Corporate Governance Factbook 2025).
2. New issuance improved materially
SEC IPO activity rose from 246 in 2024 to 374 in 2025, while total proceeds increased from $39,212.6 million to $70,130.8 million (SEC IPOs). The median deal size also climbed from $53.6 million to $105.3 million (SEC IPOs).
3. Exchange infrastructure remains deeply scaled
Nasdaq, NYSE, FESE, WFE, and TWSE each show a different angle on listed-market scale. The common pattern is that public markets support thousands of listings, trillions in capitalization, and massive daily trading activity (Nasdaq 2024 10-K; ICE 2024 10-K; FESE Annual Statistical Report 2024; WFE Dashboard: December 2024; TWSE 2024 Market Highlights).
4. Ownership runs through funds and institutions
The ICI data show 71.5 million US households owning funds and 54.4% of US households participating in funds in 2023 (ICI 2024 Fact Book Quick Facts). At the same time, OECD said institutional investors held 47% of global equity holdings and 69% of listed equity in the United States at the end of 2024 (OECD Corporate Governance Factbook 2025).
5. The public market still matters to everyday savers
The retirement and fund data are the bridge between market statistics and household finance. A $38.4 trillion US retirement market, $33.9 trillion in U.S.-registered investment company net assets, and $11.9 trillion in DC plan and IRA assets invested in mutual funds are not niche numbers; they are the financial backdrop for long-term savings in the United States (ICI 2024 Fact Book Quick Facts).
Public market statistics therefore tell a simple story with a lot of texture: the listed economy is enormous, highly centralized at the top, and still central to household wealth, institutional portfolios, and capital formation.
