Opendoor Borrowed $650 Million at 0% and Spent Part of It Buying Back Its Own Stock the Same Day

Opendoor announced on August 13, 2026 that it is issuing $650 million of convertible senior notes due August 15, 2030, and that the notes carry a coupon of 0%. At the same time, it is buying back about 45.3 million of its own shares. Both halves of that sentence are unusual, and they are connected.

What a 0% convertible actually is

A convertible note is a bond that the holder can exchange for shares instead of taking cash repayment. Because that conversion right has value, investors accept a lower interest rate than they would demand on ordinary debt — and when the right is valuable enough, they accept no interest at all.

Opendoor is therefore borrowing $650 million for four years and paying no interest on it. What it gives up instead is the possibility of dilution: if the share price rises far enough, noteholders convert and the share count grows.

The 35% premium is the price of that option. Noteholders only benefit from converting if the stock reaches roughly $4.71, so the company keeps the full upside between $3.49 and that level.

Where the $650 million goes

The headline figure is not what reaches the business. Three uses split it.

The capped call is a hedge bought from banks that offsets the dilution if conversion happens, effectively raising the price at which the company suffers real dilution. It costs cash up front — here about $52.5 million — and is standard practice alongside a convertible issue.

Why repurchase shares while raising money

This is the part that reads as contradictory. The company repurchases roughly 45.3 million shares at $3.49, about $158 million, representing 5% of shares outstanding as of July 28, 2026. It is the first repurchase in Opendoor's history as a public company, authorised by the board on August 12, 2026.

The logic is not that the company wants fewer shares and more debt for their own sake. A concurrent repurchase is a routine feature of convertible issuance because of who holds these notes. A large share of the demand comes from funds running convertible arbitrage: they own the note and run an offsetting equity hedge so that their return depends on the note's terms rather than on the direction of the share price. Establishing those hedges adds supply to the market precisely while the deal is being placed. A company repurchasing at the same moment absorbs the other side of that flow.

The net effect is that Opendoor converts part of a debt raise into a lower share count, at a price it has effectively set at $3.49, while still adding roughly $440 million of cash for expanding home inventory and market footprint. For a company whose business model is holding houses on its own balance sheet, inventory capacity is the constraint that money relieves.

What the tape recorded

The announcement crossed our tape at 10:08 UTC on August 13 — 06:08 in New York, before the regular session opened. No intraday price was available to measure the headline against in the minutes that followed, so we make no reaction claim here. The reference price that matters for the terms is the August 12 close of $3.49, which is fixed in the deal documents rather than being a market reaction to the news.
