On October 21, 2021, shares of Digital World Acquisition Corp. (DWAC) opened at roughly $10 — a typical price for a blank-check company. By October 22, the stock had hit a peak of more than $131, a surge of more than 800% from its pre-announcement price. At one point intraday, gains exceeded 1,200%.

What caused the surge? A merger announcement. But to understand why a merger announcement produced that kind of price movement, you need to understand how SPACs work — and why they create the conditions for extreme short-term volatility.

What Is a SPAC?

A Special Purpose Acquisition Company (SPAC) is a publicly traded shell company with no business operations of its own. It raises money from investors through an IPO — typically at $10 per share — with the stated goal of using those funds to acquire a private company and take it public. Because SPACs do not yet have a business when they go public, they are sometimes called "blank-check companies."

The SPAC structure solves a problem for private companies: going public through a traditional IPO is expensive, slow, and unpredictable. Merging with a SPAC is faster, cheaper, and gives the target company more control over its valuation.

For investors who buy into the SPAC at IPO, the value proposition is essentially: trust us to find a good deal. Most SPACs trade near $10 — their cash-in-trust value per share — until a merger target is announced. The announcement is when the speculation begins.

Why Did DWAC Surge So Dramatically?

Three factors combined to produce DWAC's extraordinary price movement:

1. The target was Donald Trump. The TMTG merger was not just a financial event — it was a political and cultural flashpoint. Retail investors who were politically aligned with Trump bought shares as a form of financial participation in the project. This demand was not driven by traditional discounted-cash-flow analysis. 2. SPACs structurally suppress pre-announcement information. Because SPACs are legally prohibited from disclosing their merger targets in advance, investors have no way to price in the target's value before the announcement. When the announcement comes, all of that repricing happens at once — creating the conditions for dramatic gaps between the pre- and post-announcement price. 3. Short interest and options amplified the move. When a heavily shorted stock surges, short sellers are forced to buy shares to cover their positions, pushing the price higher still. Options — contracts that give the holder the right to buy shares at a set price — become extremely valuable when a stock moves sharply, which attracts additional speculative buying.

The Structural Problem the SEC Identified

The DWAC case illustrates a fundamental tension in the SPAC model. The entire premise of a SPAC is that the sponsor finds a target after going public. But the SEC's investigation found that DWAC's sponsor had been targeting TMTG before the IPO — meaning the IPO price of $10 per share was set without investors knowing they were effectively buying into a Trump Media acquisition vehicle.

This is why the structure mattered legally, not just economically: investors made decisions based on a false premise.

The Post-Merger Reality

After the merger closed in March 2024 and the stock began trading under the ticker DJT, the share price was highly volatile and at times traded at significant premiums to the company's underlying financial metrics. TMTG reported minimal revenue — the business model of Truth Social had not yet produced substantial income — yet the stock commanded a market capitalization far in excess of what fundamental analysis would support. For economics students, this is a case study in how narrative, sentiment, and political identity can temporarily decouple market prices from fundamentals.
