How Tech Innovations Have Altered iGaming in the US

While the iGaming and remote betting market in the US remains largely immature and burgeoning in nature, it has continued to experience marked growth since 2018.

At this time, the US Supreme Court struck down the controversial PAPSA legislation, which had previously prohibited sports betting at federal level. Since then, more than 30 states have legalised this practice, contributing to a total online gambling market that was worth $2.65 billion in 2025.

Overall, online gambling in the US is expected to grow at a Compound Annual Growth Rate (CAGR) of 16.4% between now and 2028, at which point it will deliver a total of $7.61 billion.

Another key driver of this seemingly relentless growth in technological advancement. But what are the key innovations and how have they changed iGaming in the US?

#1. The Rise of Flash and HTML5 Technology

In many ways, the growth of iGaming stateside has largely been empowered by the ability of operators to tap into existing technology stacks.

These are largely owned and used by British operators like William Hill, who have entered into various strategic partnerships with US betting brands and provided considerable expertise across various verticals. This has certainly helped the US market to benefit directly from HTML5 and Flash technologies, which have helped to create more seamless and enjoyable iGaming experiences across both desktop and mobile devices.

The newly updated and integrated flash technology is particularly effective, as this drives faster average page loading times through desktop browsers. Of course, this also negates the need to download any third-party software, with only a plug-in required to access high quality games’ libraries. As for HTML5 technology, this arguably consumes even less processing power than Flash and subsequently runs a little faster.

This advanced programming language also offers considerably easier multimedia integration, which in turns makes it easier to access slots and casino games on mobile devices and browsers such as Safari and Chrome.

US casino platforms now leverage Flash and HTML5 technology to provide a more accessible, enjoyable and seamless iGaming experience across all devices, while ensuring that mobile users don’t have to compromise on graphics, audio or the number of titles that they’re able to play on the move.

#2. The Emergence of Crypto Casinos

The global blockchain marketplace also represents big business, with this sector set to grow at an incredible CAGR of 85.9% between now and 2030.

Of course, blockchain and its underlying distributed ledger technology has many applications, but it’s perhaps best known for powering cryptocurrencies and iconic first-generation tokens like Bitcoin (BTC).

The blockchain and iGaming markets have collided of late too, with the latter having observed a significant rise in the number of crypto and BTC casinos over the course of the last few years.

This trend has continued at pace in the US and UK, with many casinos now accepting various crypto tokens while offering players a diverse and increasingly secure iGaming experience (many such platforms have integrated 256-bit SSL encryption into their websites). We have also seen far more emphasis put on the security side of this, with providers increasing the level of encryption to help secure customers’ cryptocurrency.

Interestingly, the ewallet PayPal has responded to this by developing support for the transfer of selected cryptocurrencies with several different exchanges and crypto wallets

This is key, as PayPal not only offers quick, secure and low-cost transactions, but it also enables you to connect a bank account, credit card and now crypto email address to your account. Because of this, you can potentially manage multiple online casino payment methods through a single interface, making crypto and BTC gambling more accessible than ever before. This is another key factor when determining how to choose the best PayPal casinos online, while it has also increased the iGaming audience in regions such as the US, UK and Europe.

This means more unique player accounts and higher revenues for operators over time, without compromising on the overall experience or security of individual financial transactions.

#3. Creating Virtual and Augmented Reality Based Casino Games

If you look at the evolution of iGaming over the course of the last decade, you’ll see that technology has largely been focused on replicating a corporeal gambling experience online and through mobile devices. This process has involved live casino evolution and the integration of live dealers, while table game iterations of roulette and blackjack have become more authentically paced.

The next, and arguably final frontier for this evolution is being powered by virtual and augmented reality, with a number of casinos, titles and slot games now utilising VR to mirror a first-hand gambling experience in the comfort of your own home.

This has certainly helped to US market, particularly when appealing to older player demographics who are accustomed to offline casinos and brick-and-mortar establishments in locations such as Las Vegas and Atlantic City.

While AR technology (which combines both real and corporeal elements) is less widely used in iGaming, both innovations have made online gambling more popular and will continue to alter the landscape further going forward.
