Upbit Listing Notice Alert

Detect new Upbit listing announcements the instant they are posted. Capitalize on Korean exchange listing notice pumps with ultra-fast alerts.

Why Upbit listing announcements cause massive price pumps

Upbit is South Korea's largest cryptocurrency exchange, processing billions of dollars in daily trading volume. When Upbit publishes a new coin listing notice, the token's price on international exchanges (Binance, OKX, Bybit) often jumps sharply: across 67 Upbit spot listings tracked since April 2026, the median best traded price within 24 hours of the announcement was +33.2% above the last pre-announcement price (listing price reaction statistics). This is known as the "Upbit listing effect."

The Korean crypto market operates somewhat independently due to regulations, creating the famous "Kimchi premium". New Upbit listings attract massive Korean retail buying pressure, which spills over to global markets. Traders who detect Upbit listing announcements first can position on other exchanges before the pump reaches them.

How to get Upbit listing notice alerts

Connect to our WebSocket. From the Tokyo endpoint, filter for Upbit only with the ?cex=upbit parameter; the Seoul endpoint carries both Korean exchanges, so pass the same ?cex=upbit filter there if you want Upbit alone.

# Upbit listings only (Tokyo endpoint)
import json, websocket

def on_message(ws, msg):
    data = json.loads(msg)
    if data["type"] == "announcement":
        print(f"UPBIT LISTING: {data['ticker']}")
        # Execute your trade here

websocket.WebSocketApp(
    "wss://jp.cryptolisting.ws?cex=upbit",
    header=["X-API-Key: YOUR_KEY"],
    on_message=on_message,
).run_forever()

Three endpoints — pick the closest to your bot

We dispatch Upbit listings from two AWS regions — Tokyo and Seoul; the third endpoint, N. Virginia, carries Robinhood only. Same API key works on all three. Pick by your bot's location, not by what you trade:

• Tokyo — wss://jp.cryptolisting.ws — global feed (Binance, Upbit, Bithumb). Best if your bot lives in AWS Tokyo / Asia-Pacific (Japan). Seoul → Tokyo network hop on the Upbit detection side.
• Seoul — wss://kr.cryptolisting.ws — Korea-region mirror in AWS Seoul, carrying Upbit and Bithumb. Best if your bot is co-located in Korea and trades Upbit. Eliminates the Seoul → Tokyo detection hop: ultra-fast end-to-end.

Quick start — Seoul endpoint from a Korea-based bot:

Upbit listing notice detection speed

We monitor Upbit's announcement and notice channels continuously, 24 hours a day. When a new listing notice is published, we detect it and broadcast the structured event to every connected subscriber within milliseconds. Two endpoints, two latency profiles: from wss://jp.cryptolisting.ws (Tokyo), the announcement crosses a Seoul → Tokyo network hop on the detection side — Upbit's servers are in Seoul. From our Seoul endpoint wss://kr.cryptolisting.ws, that hop disappears: a Korea-based trading bot gets ultra-fast end-to-end. The Seoul endpoint dispatches both Korean exchanges, Upbit and Bithumb — purpose-built for Korea-based traders.

Either way, we are faster than any other listing alert provider — including other WebSocket services. Our edge comes from purpose-built low-latency infrastructure optimized at every layer. No unnecessary overhead.

Upbit vs Binance listing announcements

Both exchanges cause significant price movements on listing notices, but the dynamics differ. Binance listing announcements tend to have a more gradual impact because Binance is globally accessible. Upbit listing notices create sharper, faster pumps because the Korean market reacts explosively, and international traders need time to catch up. This makes speed even more critical for Upbit announcements.

Multi-exchange monitoring

You don't have to choose. Subscribe to both Upbit and Binance simultaneously:

"wss://jp.cryptolisting.ws?cex=upbit,binance"

Or leave the cex parameter empty to receive listing announcements from all monitored exchanges (Binance, Upbit, Bithumb — plus Robinhood on its own US endpoint — and more as they are added). See the full API reference for details.

Upbit listing WebSocket API & KRW market notices

Stream Upbit KRW market listing notices over our real-time WebSocket API. Each notice — new listings, caution releases and trading-support (거래지원) changes — arrives as structured JSON with microsecond timestamps, ready for your bot. A dedicated Seoul endpoint gives Korea-based bots the lowest end-to-end latency. Building a bot? Follow the Upbit & Bithumb listing bot tutorial in Python, and see what a caution release (유의종목 지정 해제) means.

Frequently asked questions

What kind of Upbit listings does CryptoListing.ws cover?

All new KRW market listings on Upbit, the dominant Korean exchange. We deliver each new Upbit KRW listing within milliseconds of publication. Use ?cex=upbit to subscribe to Upbit only, or combine with bithumb for full Korean market coverage.

Why are Upbit listings important for traders?

Upbit KRW listings regularly produce Kimchi premium moves: Korean retail demand is large and the local won market is segmented from global liquidity. Across 67 Upbit spot listings tracked since April 2026, the median best traded price within 24 hours of the announcement was +33.2% above the last pre-announcement price — a peak, not a guaranteed return. Full figures: listing price reaction statistics.

Should I use the Tokyo or Seoul endpoint?

For Upbit specifically, our Seoul endpoint offers the lowest latency since both our Seoul endpoint and Upbit's infrastructure are in Korea. The Tokyo endpoint adds a Japan-Korea network hop. If your trading bot is hosted in Korea, use Seoul; if hosted globally, Tokyo is fine for most strategies.

How does latency to Korea affect my fills?

Network round-trip from Tokyo to Seoul is roughly 36 ms. From the US it can exceed 150 ms. For Upbit listing pumps that can move tens of percent in seconds, every saved millisecond matters. SpeedTrial lets you measure real end-to-end timing from your own infrastructure.

Can I subscribe to Upbit and Binance together?

Yes. Use ?cex=upbit,binance on a single connection to receive announcements from both exchanges through one WebSocket stream. The publisher field on each message tells you which exchange it came from, so your bot can route orders to the correct venue.

How do I get Upbit announcements in English?

Upbit publishes its listing announcements in Korean on its official notice page. CryptoListing.ws normalizes each Upbit announcement into a structured, language-neutral WebSocket message — the ticker, listingType and market fields are the same regardless of the original Korean text — and pushes it in real time within milliseconds of publication. You do not need to read Korean or run a translator: subscribe with ?cex=upbit and parse the fields directly. The free SpeedTrial tier lets you test the live Upbit feed at zero cost before choosing a plan.
