Braze stock jumped 51.5% to $45.51 on October 20. The jump came after Salesforce agreed to buy the company for $47.50 a share in cash. After the jump, Braze shares traded below the price Salesforce promised to pay. Traders have a name for that gap. Its size shows how investors price a deal that has not closed.
The deal in two numbers
Salesforce signed a definitive agreement to buy Braze. Braze makes software that businesses use to message their customers. A definitive agreement is a signed contract. It goes a step past early talks or a letter of interest.
Holders of Braze Class A common stock will receive $47.50 in cash for each share they own. Class A common stock is a type of ordinary Braze share.
Salesforce valued the deal at about $5.66 billion in enterprise value. Enterprise value is the price of the whole business. To get it, you start with the value of the shares. You add the company's debt and subtract its cash.

Salesforce stock fell 1.4% on the same day, as of 1:48 p.m. Eastern time. The S&P 500, an index that tracks 500 large US companies, rose 0.28% by the end of trading.
This split is common on the day a buyer announces a deal. The buyer's stock slips, and the target, the company being bought, jumps. The buyer's shareholders give up company cash. The target's shareholders receive it.
The gap between $45.51 and $47.50
At $45.51, Braze traded below the $47.50 offer. Traders call this gap the deal spread. It is the difference between the target's market price and the cash the buyer has agreed to pay.

A holder who could collect $47.50 the next morning would not sell for $45.51. The gap exists because Salesforce has not paid. The payment might not arrive at all.
Merger arbitrage traders are a group of investors who build a business on this gap. They buy the target's shares after a buyer announces a deal. They hold those shares until closing, the day the deal completes. At closing, the buyer pays the agreed cash. The trader keeps the difference.
On deal day, the two sides of that trade meet. Some Braze holders sold on October 20 and locked in the jump. Arbitrage traders bought those shares at a price that left room for their own return. The $45.51 price is where those two groups agreed.
Buyers of those shares earn the gap as payment for two things: time and risk.
The first cost: waiting
Salesforce expects the deal to close in its fiscal year 2028. A fiscal year is the yearly period a company uses for its accounts. Salesforce's fiscal year runs on its own schedule, separate from the calendar year.
A trader who buys Braze at $45.51 ties up money until closing. That money could earn interest somewhere else in the meantime. On October 20, the 10-year yield closed at 5.12%. The 10-year yield is the interest rate the US government pays to borrow for 10 years. It gives a rough sense of what a saver can earn on safe money while waiting.
The longer the wait, the more interest a trader gives up. Traders demand a wider gap for a longer wait. Higher interest rates add to the cost of waiting. Traders tend to price a deal due to close within weeks nearer its offer than one expected to take a year or more.
The second cost: the deal could fail
Salesforce listed what it called customary closing conditions. These are the standard steps a deal must clear before it closes. Braze's shareholders must vote to approve the deal. The companies must receive the required regulatory approvals. Regulators here are the government agencies that review mergers for harm to competition.
If either step fails, the deal can collapse. Braze stock would lose the support of the $47.50 offer. It could drift back toward the price it held before October 20.
That makes the trade lopsided. If the deal closes, the trader earns the gap between $45.51 and $47.50. If it breaks, the trader can give back much of the 51.5% jump. A small, likely gain sits against a large, less likely loss.
Traders set the size of the gap as their rough price for those odds. A narrow gap means traders see little risk and a short wait. A wide gap means they see more of one or both.
The risk Salesforce removed
Salesforce expects to pay for Braze with cash. The company said that, for now, it does not expect to need debt financing. Debt financing means paying with borrowed money. Traders factor that detail into the spread.
Some buyers depend on borrowed money to pay for a deal. If lenders pull back or borrowing costs climb, the buyer can struggle to fund the purchase. Traders call this financing risk, and they widen the gap to cover it. By paying with cash, Salesforce takes that risk off the list.
The cash payment removes a second link. In a stock deal, the buyer pays with its own shares. The target's price moves up and down with the buyer's stock. Braze holders are due a fixed $47.50 in cash. Salesforce's 1.4% drop on October 20 does not change that amount.
That leaves two main risks inside the Braze gap: the approvals and the wait.
Reading a deal spread for yourself
You can watch the same mechanics in any announced cash deal. The offer sets the anchor. The expected closing date and the odds of approval set the gap below it.
If Braze's price moves closer to $47.50, traders are pricing less risk or a shorter wait. If it moves further from the offer, they are pricing more. Traders can move the gap either way on news about the shareholder vote or the regulatory reviews.
Interest rates are a separate input. The Federal Reserve, the US central bank, holds its policy meeting on October 27 and 28. The Fed is due to announce its rate decision on October 28. The Fed uses that rate to set the return on cash held in the banking system. Traders use that return as the yardstick for the cost of waiting.
If you own either stock
If you own Braze, the stock trades as a claim on a future cash payment of $47.50. The offer anchors its price while the deal waits to close. Traders move it more on approval news and the cost of money than on Braze's quarterly results.
If you own Salesforce, the deal is a use of the company's cash. Salesforce stock dipped 1.4% on deal day, a day the broad index rose.
The gap between $45.51 and $47.50 is the price traders put on time and doubt. Watch it to see how sure they are the deal will close, and how long they expect to wait.
