Kalshi launches $10 promo code "DIMERS for "The Open" live odds

The Kalshi code DIMERS has officially launched for The British Open, now guaranteeing a $10 Kalshi sign-up bonus after their first $10 trade on the platform. Registering on Kalshi with the code DIMERS takes under five minutes and provides immediate access to Kalshi's full prediction market catalog — including the golf markets currently live for The Open Championship on July 16th.

The Kalshi code DIMERS is the same code whether you find it described as a Kalshi referral code, a Kalshi promo code, or simply a Kalshi code. These terms are used interchangeably across the platform and its affiliate network — they all refer to the same registration code that triggers the sign-up bonus and unlocks a new account. This article explains the difference, confirms the current Kalshi sign-up bonus offer, and covers what Kalshi odds are showing for The Open Championship.

How to Use the Kalshi Promo Code DIMERS for The Open:

1. Visit Kalshi.com or download the Kalshi app.
2. Create a new account and enter the Kalshi code DIMERS in the referral or promo code field during sign-up.
3. Complete identity verification — required for all new Kalshi accounts.
4. Place your first trade of $10 — your $10 Kalshi sign-up bonus is credited immediately after.
5. Bonus funds are available on all open Kalshi prediction market contracts.

Important: The Kalshi code DIMERS must be entered at registration. It cannot be applied to an account that already exists.

Kalshi Referral Code vs. Kalshi Promo Code vs. Kalshi Code: Is There a Difference?

One of the most common questions Dimers readers have when searching for a Kalshi code is whether a "Kalshi referral code," a "Kalshi promo code," and a "Kalshi code" are different things. The short answer: no. All three terms describe the same registration field on Kalshi's sign-up page, and entering DIMERS in any of them activates the same $10 Kalshi sign-up bonus.

The terminology varies because different affiliates, review sites, and users describe the same code field in different ways. Kalshi itself labels the field differently across its web and app interfaces — sometimes "referral code," sometimes "promo code," sometimes simply "code." Regardless of what the field is labeled when you register, the Kalshi code DIMERS works in all of them.

What matters is that the code is entered at registration — not after the fact — and that the account is new. The Kalshi code DIMERS cannot be applied retroactively, and the sign-up bonus is limited to one per user.

Is Kalshi Betting? What "Kalshi Betting" Actually Means

Searches for "Kalshi betting" are common — and understandable. For most people in the US, trading on the outcome of a golf tournament maps intuitively to the concept of sports betting. But Kalshi operates under a fundamentally different legal and structural framework than a sportsbook, and the distinction is worth understanding before you fund an account.

Kalshi is not a sportsbook. It is a CFTC-regulated prediction market exchange — the first federally licensed prediction market in the United States. On a sportsbook, you place a bet against the house, which has built a margin into every line it offers. On Kalshi, you trade a contract against another user through a regulated exchange. There is no house on the other side. Kalshi earns a small transaction fee on each trade, but it does not set prices or take positions against users.

When people search "Kalshi betting," what they are typically looking for is: can I trade on golf outcomes on Kalshi, and how does it work? The answer is yes — Kalshi has active golf markets, including a full outright winner market for The Open Championship, and the Kalshi code DIMERS gives new users funded access to those markets from day one. But the mechanics of how Kalshi works are closer to trading a financial contract than placing a wager.

This distinction also has practical implications:

• No house edge baked into the price. Kalshi odds reflect exchange supply and demand — not a sportsbook margin.
• You can exit a position before resolution. If you buy a Kalshi contract at 60¢ and it moves to 75¢, you can sell your position for a profit before the event concludes — just like trading a stock.
• Kalshi is available in US states where prediction market trading is permitted — a footprint governed by its CFTC-regulated status, though its sports contracts remain the subject of active litigation.

Polymarket vs. Kalshi: Which Platform and Code Is Right for The Open Championship?

The Polymarket vs. Kalshi question is the most common comparison Dimers readers face when evaluating US prediction markets. Both platforms are legal, both carry the code DIMERS for new users, and both have active golf markets for The Open Championship. Here is the full side-by-side:

The Polymarket code DIMERS (Trade $20, Get $50) offers a larger sign-up bonus and higher total trading power — $70 vs. $20 — at a higher deposit threshold. The Kalshi code DIMERS (Trade $10, Get $10) has a lower barrier to entry and is the right choice for traders who want Kalshi's specific regulatory framework, its political and economic market catalog, or its limit-order exchange structure.

On The Open Championship specifically, both boards agree on the shape of the field: Scottie Scheffler is the clear favorite on both (12% on each), with Rory McIlroy second and the English duo of Matt Fitzpatrick and Tommy Fleetwood close behind. The Polymarket vs. Kalshi decision does not have to be exclusive. Both codes can be activated simultaneously — each code applies to a separate platform registration, and the bonuses do not conflict.
