This article is for bettors who need to understand what WebRTC and HLS actually are, why the technical differences matter for betting outcomes, and whether upgrading to faster streaming can actually give you an edge.
What HLS and WebRTC Actually Are
HLS stands for HTTP Live Streaming. It's the dominant streaming protocol used by most major platforms - Netflix, YouTube, traditional sports streaming apps. HLS was designed in 2009 by Apple to solve a specific problem: delivering smooth, high-quality video over inconsistent internet connections.HLS works by breaking video into small chunks (usually 6-10 seconds each), encoding those chunks at multiple quality levels, and delivering them to your device via standard web protocols. Your device buffers several chunks ahead of what you're currently watching to prevent stuttering if your connection drops momentarily.
That buffering is great for video quality. It's terrible for live betting. Those 6-10 second chunks, plus encoding time, plus buffering, plus network transit time, add up to 15 to 45 seconds of latency depending on your connection quality and the platform's configuration.
WebRTC stands for Web Real-Time Communication. It was designed for video conferencing - think Zoom or Google Meet - where latency kills the experience. Nobody wants a 20-second delay when they're trying to have a conversation. WebRTC prioritizes speed above everything else.
Instead of chunking video and buffering ahead, WebRTC streams in real-time with minimal buffering. It accepts some risk of stuttering or quality drops in exchange for getting the video to you as fast as physically possible. Latency with WebRTC typically runs under 1 second, often as low as 500 milliseconds or less.
For watching a movie, HLS is superior. For betting on the outcome of the next corner kick, WebRTC is the only protocol that gives you a fighting chance.
Why Latency Matters More Than You Think
A 20-second delay doesn't sound significant until you map it onto the pace of a football match. A counterattack from midfield to a shot on goal takes maybe 8 seconds. A corner kick from awarded to taken to cleared is 5 seconds. A throw-in is 3 seconds.If you're watching on HLS with a 20-second delay, you're seeing events that happened 20 seconds ago. When you place a bet on "Next Team to Score" because you see the home team pressing high, that pressing sequence already ended 15 seconds ago. The ball's already back at midfield, the attack is over, and the market has moved on.
The sportsbook isn't watching your HLS stream. They're receiving data from official feeds that are faster than broadcast, sometimes from scouts physically at the stadium transmitting in real time. When an event happens, the book's odds algorithm reacts within milliseconds.
You're betting based on information that's 20 seconds old against an algorithm processing information that's 0.2 seconds old. That's not a competitive disadvantage. That's structural impossibility. You can't overcome a 20-second information gap with better analysis or faster decision-making.
The Technical Breakdown: Why HLS Is Slow
HLS wasn't designed for speed, so understanding why it's slow helps you understand why it's everywhere despite being terrible for betting.Chunking and Segmentation
HLS breaks video into segments. Each segment is typically 6 seconds long. That means the platform has to wait for 6 seconds of video to happen, encode it, upload it to a server, then deliver it to your device. Right there, you've added 6+ seconds before the video even starts traveling to you.
Adaptive Bitrate Streaming
HLS creates multiple versions of each chunk at different quality levels (480p, 720p, 1080p). Your device picks the appropriate quality based on your connection speed. This switching takes time and adds latency as your device requests different quality tiers.
Buffering
To prevent stuttering, HLS buffers 2-3 chunks ahead of what you're watching. If each chunk is 6 seconds, that's 12-18 seconds of buffering. Combined with encoding and delivery time, you're looking at 15-25 seconds of latency under good conditions, 30-45 seconds under poor conditions.
CDN Distribution
HLS uses Content Delivery Networks (CDNs) to distribute video globally. The video might travel from the stadium to a CDN server in one region, then to another CDN closer to you, then to your device. Each hop adds latency.
All of these design decisions make sense for on-demand video or live streams where a 30-second delay doesn't matter. For live betting where events resolve in 5 seconds, these delays are catastrophic.
How WebRTC Solves the Latency Problem
WebRTC takes the opposite approach. Instead of optimizing for quality and reliability, it optimizes for speed.No Chunking
WebRTC streams continuously without breaking video into segments. There's no "wait 6 seconds to encode a chunk" step. Video is encoded and transmitted as fast as the connection allows.
Direct Peer-to-Peer Connection
WebRTC establishes a direct connection between the video source and your device when possible, bypassing CDN infrastructure. Fewer hops means less latency. When peer-to-peer isn't possible, WebRTC uses optimized relay servers that prioritize speed over distribution.
Minimal Buffering
WebRTC buffers only what's necessary to handle tiny network hiccups - often just a few hundred milliseconds. If your connection drops, you'll see stuttering or freezing rather than smooth playback from a buffer. That's a tradeoff WebRTC makes intentionally: accept occasional quality issues to minimize delay.
Adaptive Quality in Real-Time
Like HLS, WebRTC adjusts quality based on connection speed. But instead of switching between pre-encoded chunks, WebRTC adjusts encoding on the fly. This happens faster and with less latency penalty.
The result is sub-second latency. In optimal conditions, WebRTC can deliver video with 300-500ms delay. Even under poor conditions, it rarely exceeds 2 seconds.
For live betting, that difference is everything. At 500ms latency, you're seeing the corner kick roughly when it happens. At 20 seconds latency, you're seeing it after it's resolved.
The Tradeoffs: Why Not Everyone Uses WebRTC
If WebRTC is so much faster, why doesn't every platform use it? Because speed comes at a cost.Video Quality
WebRTC accepts lower video quality when necessary to maintain speed. If your connection can't handle 1080p in real-time, WebRTC will drop to 720p or lower without buffering ahead to smooth things out. HLS would buffer and deliver 1080p with a delay. For entertainment viewing, HLS looks better.
Infrastructure Cost
WebRTC requires different server infrastructure than HLS. CDNs are optimized for HLS delivery. Switching to WebRTC means building or buying new infrastructure, which is expensive. Mass-market platforms prioritize cost efficiency over speed.
Device Compatibility
Older devices and browsers don't support WebRTC well. HLS works everywhere because it's just HTTP requests - any device with a web browser can handle it. WebRTC requires newer standards and more processing power. Platforms that want maximum reach stick with HLS.
Scale
HLS scales easily to millions of viewers because CDNs distribute the load. WebRTC's peer-to-peer model works well for smaller audiences but gets complicated at scale. A major sporting event with 10 million viewers is easier to deliver via HLS.
These tradeoffs explain why mass-market streaming apps still use HLS. For Netflix or YouTube, a 20-second delay doesn't matter. For mainstream sports apps targeting casual viewers who aren't betting, quality and reliability matter more than speed.
But for betting platforms targeting serious bettors, speed is the only thing that matters. That's why the industry is splitting.
The Tiered Betting Experience in 2026
The betting landscape in 2026 has effectively created two classes of bettors based on streaming technology.Tier 1: WebRTC Platforms for Sharp Bettors
Some crypto sportsbooks, Asian bookmakers, and betting exchanges have adopted WebRTC streaming. These platforms cater to high-volume, informed bettors who need real-time data to make decisions. The video quality might be worse, the stream might stutter occasionally, but the latency is under 1 second.
If you're betting on these platforms, you're seeing events roughly when they happen. You're not fully level with court-siders who are physically present, but you're close enough that your football analysis matters more than your information speed.
Tier 2: HLS Platforms for Recreational Bettors
Most regulated US and UK sportsbooks still use HLS or rely on third-party broadcasters with HLS feeds. These platforms target recreational bettors who prioritize ease of use and video quality over speed. The stream looks great, it never stutters, but you're 15-30 seconds behind.
If you're betting on these platforms, every live bet you place is fighting against structural latency. You think you're making informed decisions, but you're reacting to outdated information. The platform knows this, accepts it, and prices markets accordingly.
The gap between Tier 1 and Tier 2 is the gap between competitive live betting and entertainment betting disguised as competitive betting.
Can You Tell Which Protocol You're Using?
Most platforms don't advertise their streaming protocol. They just say "watch live" without specifying whether that's real-time or 30-second-delayed live.Here's how to check:
Compare to Live Score Apps
Open a live score tracking app (Fotmob, FlashScore, ESPN) alongside your betting stream. These apps receive official data feeds that are usually faster than broadcast. If the score updates on the app 15+ seconds before you see the goal on your stream, you're watching HLS.
Look for "Low Latency" or "Real-Time" Marketing
Platforms using WebRTC often advertise it as a competitive advantage. They'll use phrases like "sub-second latency," "real-time streaming," or "low-latency video." If you don't see this language, assume HLS.
Test the Delay
If you have access to another source showing the same match (TV broadcast, another streaming service), play them side-by-side. The delay between them tells you which is faster. WebRTC should be within a second of the fastest available source.
Check Your Video Quality
If the stream looks flawless and never stutters even on a mediocre connection, it's probably HLS with heavy buffering. If the quality fluctuates and you see occasional freezing, it might be WebRTC prioritizing speed.
Most bettors never check. They assume "live" means real-time and don't realize they're betting 20 seconds into the past.
Does WebRTC Actually Give You an Edge?
Having a faster stream doesn't guarantee profit, but it eliminates one major structural disadvantage.If you're betting micro-markets (next corner, next throw-in, next point scored), WebRTC is the minimum requirement to not be systematically exploited. Even with WebRTC, you're still competing against court-siders and official data feeds that are faster, but you're close enough that your analysis can matter.
If you're betting broader markets (next goal in the next 15 minutes, final result, total goals), the protocol matters less. A 20-second delay doesn't change the analysis when you're betting on outcomes that play out over 10-20 minutes. You're looking at tactics, fatigue, substitutions - things that don't resolve in seconds.
The real value of WebRTC is it removes the gaslighting. With HLS, you feel like you're making informed decisions when you're actually blind. With WebRTC, you're at least seeing what's happening when it's happening. Whether you make good decisions with that information is up to you.
Why Mainstream Books Aren't Switching to WebRTC
If WebRTC is better for betting, why aren't DraftKings, FanDuel, and Bet365 switching?Because their customers don't demand it. Recreational bettors don't know the difference between HLS and WebRTC. They see a stream, they bet, they lose, they don't question whether the stream was delayed. The book makes more money from these customers than they would from sharp bettors on WebRTC who might actually win.
There's also a cynical calculation: if recreational bettors are betting into delayed information, they're more likely to lose. The house edge is effectively higher because bettors are making decisions based on outdated data. Why would the book fix that?
Sharp books that want to attract informed bettors switch to WebRTC because speed is a selling point to that audience. Recreational books that want to maximize handle from casual users stick with HLS because it's cheaper and their customers don't care.
The market is segmenting. If you're serious about live betting, you migrate to platforms with WebRTC. If you're betting for fun, you stay on HLS platforms and accept that you're paying for entertainment rather than competing on fair terms.
The Future: Will HLS Disappear?
Probably not entirely, but the trend is clear. As WebRTC infrastructure improves and becomes cheaper, more platforms will adopt it for betting streams even if they keep HLS for non-betting video content.Some platforms are implementing hybrid systems: HLS for the main broadcast with better quality, and a separate WebRTC stream for users actively betting. This gives casual viewers the smooth experience they expect while offering serious bettors the speed they need.
The economic incentive is there. Platforms that can credibly claim "real-time streaming" have a competitive advantage when courting sharp bettors and high-volume users. As those users continue migrating away from mainstream books toward offshore and crypto platforms with better latency, regulated books will eventually need to compete on speed or lose that segment entirely.
But the mass market will probably stay on HLS for years. Most people betting $20 on a Sunday game don't know what latency is and don't care. They're betting for entertainment, not edge. HLS is good enough for that use case.
The split is permanent: WebRTC for serious bettors, HLS for everyone else.
What You Should Do About This
If you're betting live with any frequency, find out what protocol your platform uses.If you're on HLS and betting micro-markets, you're getting robbed. Either switch to a WebRTC platform or stop betting those markets. There's no analysis good enough to overcome a 20-second information disadvantage on events that resolve in 5 seconds.
If you're on HLS and betting broader markets, the protocol matters less but you should still shop for better options. Faster information is always better, even if it's not always decisive.
If you're on WebRTC, you're at least playing the same game as other informed bettors. You're still behind court-siders, still behind official data feeds, but you're close enough that skill matters.
The uncomfortable reality is that most bettors will never switch because they don't know this distinction exists. Books don't advertise "our stream is 30 seconds delayed," they just say "watch live and bet in-play." The information asymmetry is built into the marketing.
If you're reading this, you now know. What you do with that knowledge is up to you.
FAQ
Can I use a VPN to get faster streams?Probably not. VPNs often add latency rather than reduce it because your traffic has to route through the VPN server. The protocol (HLS vs WebRTC) matters more than your connection routing. If anything, a VPN makes HLS slower.
Will WebRTC work on my phone?
Most modern smartphones support WebRTC through their browsers and apps. Older devices might struggle with the processing requirements, but anything from the last 3-4 years should handle it fine.
Why doesn't the book just tell me which protocol they use?
Because they don't want you thinking about latency. If recreational bettors realized their stream was 20 seconds delayed, they might stop betting live or demand better technology. Books benefit from bettors not knowing they're disadvantaged, so they don't advertise the delay.
