Types of US Market Debuts: Traditional IPO vs Direct Listing vs SPAC Explained

When a US company decides to go public, it has three main routes to choose from: a Traditional IPO, a Direct Listing, or a SPAC. Each route works differently, and understanding the difference helps you make smarter decisions when you want to apply for a US IPO or invest in newly listed US stocks..

Why US Companies Don't All Take the Same Route to Go Public

In India, almost every company that goes public follows the same SEBI-regulated IPO process. You apply through your broker, shares are allotted, and the stock lists on NSE or BSE on a fixed date.

The US market works differently. The Securities and Exchange Commission (SEC) allows companies three distinct ways to list their shares on US exchanges. Each route has different rules around who gets to buy early, how the share price is set, and what protections exist for retail investors.

Route 1: Traditional US IPO — The Most Common Path

A traditional US IPO is what most people mean when they say a company "went public." The company creates new shares, sells them to the public through a structured process, raises fresh capital, and lists on a US stock exchange like NYSE or NASDAQ. It remains the most common route for US companies to go public.

How a Traditional US IPO Works (6-12 Month Process)

The process typically takes 6 to 12 months from start to finish. Here is how it unfolds:

Step 1: Hire Investment Banks The company hires investment banks called underwriters. These are firms like Goldman Sachs, Morgan Stanley, or JPMorgan. The lead underwriter is called the "book-runner" and manages the entire process.

Step 2: File the S-1 The company files an S-1 registration statement with the SEC. This is a detailed public document covering the company's financials, business model, key risks, and how it plans to use the money it raises.

Step 3: SEC Review The SEC reviews the S-1 and can ask for revisions or clarifications. This review process typically takes 75 to 120 days.

Step 4: The Roadshow Company executives travel to meet large institutional investors such as pension funds, mutual funds, and hedge funds. The goal is to build interest and get a sense of what price investors are willing to pay.

Step 5: Pricing Based on the demand built during the roadshow, the underwriters set the IPO price. This is the price at which shares are first sold — almost always to institutional investors, not retail buyers.

Step 6: Listing The stock starts trading on the exchange. The opening price on Day 1 is set by live market demand and is often different from the IPO price.

Who Underwrites the IPO? (Goldman Sachs, Morgan Stanley, JPMorgan)

Investment banks do more than just handle the paperwork. They also guarantee the company will raise the amount it is targeting. If institutional demand falls short, the underwriters step in and buy the unsold shares themselves.

For major IPOs, multiple banks share the role. Goldman Sachs and Morgan Stanley, for example, co-underwrote Airbnb's IPO.

Pros and Cons of Traditional IPO for Indian Investors

Pros:

• Large, established companies typically choose the traditional IPO route, which can serve as a quality signal
• The S-1 is a publicly available document, giving you detailed financial information to research before you buy
• Strong SEC oversight means the company has been thoroughly scrutinised before listing

Cons:

• The IPO price is set by institutions. By the time you buy on Day 1, you are often paying a premium over what institutions paid
• Lock-up periods, typically 90 to 180 days, prevent insiders from selling after listing. Once those lock-ups expire, a wave of insider selling can push the price down
• A large first-day jump does not automatically make the stock a good buy at that level

Route 2: Direct Listing — Going Public Without Issuing New Shares

In a direct listing, a company lists its existing shares on a stock exchange without creating new shares or hiring underwriters. No fresh capital is raised. The company simply opens a market for shares that already exist, held by early employees, founders, and venture capital investors.

Spotify used this route in April 2018. Slack followed in 2019, Palantir in 2020, and Coinbase in 2021.

What is a Direct Listing? (No Underwriters, No New Shares Issued)

Here is a simple way to think about it. In a traditional IPO, the company bakes a new cake and sells slices to the public. In a direct listing, the company just opens a shop where people who already own cake slices can sell them to anyone who wants to buy.

Because no new shares are created, the company does not raise fresh capital. Instead, existing shareholders such as early investors and employees get a chance to sell their shares to public buyers from Day 1.

There is no institutional pre-allocation and no IPO price. The opening price on Day 1 is set entirely by the natural supply and demand between buyers and sellers on the exchange.

Note: In a direct listing, no investment bank sets an IPO price. Instead, financial advisors assign a reference price the day before listing as a rough market anchor. The actual opening price is set entirely by live buyer and seller activity on the exchange.

Direct Listing vs Traditional IPO: 5 Key Differences for Investors

The most important takeaway: in a direct listing, there is no pre-set IPO price that institutions paid at a discount. The stock opens at whatever the market decides. This can mean more volatility on Day 1, but it also means the opening price reflects genuine market demand rather than a negotiated institutional price.

Can Indian Investors Buy Shares in a Direct Listing?

Yes. Once a company lists on NYSE or NASDAQ through any method, you can buy its shares on INDmoney exactly as you would buy any other US stock. There is no difference in how you access the shares after listing, regardless of whether the company used a traditional IPO, a direct listing, or a SPAC.

Route 3: SPAC — The 'Blank Check Company' Route to Public Markets

A SPAC, or Special Purpose Acquisition Company, is a shell company with no actual business of its own. It goes public through an IPO, raises money from investors, and then uses that money to acquire a private company and bring it to public markets.

SPACs became extremely popular between 2019 and 2021. DraftKings, Lucid Motors, Virgin Galactic, and OpenDoor all went public this way. The results for most retail investors who stayed invested have not been good.

What is a SPAC?

Imagine you read a headline: "Blank Check Company Raises $500 Million in IPO." That blank check company is a SPAC.

Here is what makes it unusual. When you buy into a SPAC IPO, you do not yet know which company it will eventually acquire. You are trusting the SPAC's management team to find a worthwhile target within a set timeframe. If they find a company you like, you hold. If you do not like the target, you can redeem your shares for the original purchase price (typically $10 per share in the US market).

This is why it is called a blank check company. You hand over the money before knowing exactly where it will go.

How a SPAC Works: The 4-Step Process

Step 1: SPAC IPO The SPAC lists on a stock exchange and raises money from public investors. Shares are typically priced at $10 each. The cash goes into a trust account where it earns interest while the management team searches for a target.

Step 2: Search for a Target (18-24 Months) The SPAC's management team, called the "sponsor," has 18 to 24 months to find a private company to acquire. If no deal is completed in that window, the SPAC dissolves and investors receive their money back from the trust.

Step 3: Shareholder Vote Once a target is identified, SPAC shareholders vote on whether to approve the deal. Investors who do not like the chosen target can redeem their shares for the trust value instead of participating in the merger.

Step 4: De-SPAC Merger If the vote passes, the SPAC merges with the target company. The previously private company becomes publicly listed, either taking a new stock ticker or inheriting the SPAC's. This event is called a de-SPAC transaction.

Famous SPAC Deals: DraftKings, Lucid Motors, Virgin Galactic, OpenDoor

DraftKings (2020): Online sports betting company DraftKings went public by merging with Diamond Eagle Acquisition Corp. The stock climbed from around $10 at the time of the merger to over $70 in March 2021, a gain of more than 500% in under a year. One of the rare SPAC success stories.

Lucid Motors (2021): Electric vehicle maker Lucid merged with Churchill Capital Corp IV. The stock surged past $55 in early 2021 on expectations of competing with Tesla. By 2025, Lucid's share price had fallen to well below $5, a decline of over 90% from its peak.

Virgin Galactic (2019): Space tourism company Virgin Galactic merged with Social Capital Hedosophia. The stock rose sharply after the merger on hype around commercial spaceflight, then declined steadily as launch timelines kept getting extended.

OpenDoor (2020): Real estate technology company OpenDoor merged with Social Capital Hedosophia II. It peaked during the 2021 housing boom and fell sharply as rising interest rates hurt demand for its business model.

The pattern is consistent: SPACs often attract companies that either could not meet the bar for a traditional IPO or preferred to avoid the scrutiny of that process. Many of those companies were early-stage, heavily loss-making, or reliant on optimistic multi-year projections.

Why Many SPACs Disappoint: The Track Record

The data on SPAC performance is discouraging for retail investors. Research by academics Michael Klausner and Michael Ohlrogge, published in peer-reviewed finance journals, found that the average SPAC stock returned approximately negative 40% or more within 12 months of completing its merger.

Several structural reasons explain this:

• Sponsor Dilution: SPAC sponsors typically receive 20% of the SPAC's shares for free as their compensation, often called "founder's shares." This dilutes the value of every other shareholder's stake before the target company even lists.
• Information Imbalance: Sponsors spend months negotiating with the target and know far more about the company's condition than public investors do. This imbalance tends to work against retail investors.
• Redemption Erosion: When a large percentage of shareholders redeem their shares before the merger closes, the SPAC ends up with significantly less cash. This weakens the combined company's financial position from the very start.
• Hype-Driven Valuations: Many SPAC mergers were announced at sky-high valuations built on projections about revenues the company had not yet earned. When those projections failed to materialise, share prices fell sharply.

The SEC moved to address these issues beginning in 2022 with proposed rules requiring stricter disclosures in SPAC merger documents and changes to how forward-looking financial projections could be presented to investors. SPAC deal activity dropped significantly following the regulatory tightening.

Traditional IPO vs Direct Listing vs SPAC Listing Comparison

Which Type Should Indian Investors Pay Attention To?

For most Indian investors buying US stocks on INDmoney, the practical answer is straightforward. Focus on traditional IPOs and direct listings from companies with established revenue and a clear business model.

Traditional IPOs from well-known companies come with extensive public disclosure through the S-1 filing. You can read through the financials, understand the risks, and make an informed decision before buying on Day 1.

Direct listings offer the same access for you after listing, with the added feature that the opening price is set by pure market demand rather than by institutions who may have paid a discounted IPO price.

SPACs are a different category entirely. The combination of sponsor dilution, information imbalance, and a documented track record of post-merger underperformance makes them a high-risk choice. Unless you have done detailed research on both the SPAC and its acquisition target, and you fully understand the dilution mechanics, SPACs are better suited to experienced investors who can absorb the risk.
