Concrete ($CT): Exchange Listing Timeline

TL;DR

Concrete ($CT)’s TGE and initial spot-market launches were concentrated on September 30, 2026. The earliest record is Binance Alpha at 08:00 UTC, followed by spot trading on Coinbase, Bitget, Gate, OKX, and others at around 10:00 UTC. Additional perpetual markets followed on October 1, before listings on Upbit and Bithumb on October 19 expanded its presence in the Korean market.

As of 2026-10-23 UTC, the user-supplied records show $CT across trading platforms including Binance Alpha, Coinbase, OKX, Gate, Bitget, Upbit, Bithumb, Bybit, and Binance. Binance Alpha is distinct from spot trading on Binance’s main exchange.

Key Milestones

The supplied material cites official Concrete information stating that $CT’s Token Generation Event (TGE) was September 30, 2026. Official Concrete announcement

The listing sequence shows the following launch path:

1. September 30: TGE + Alpha / major spot markets
2. September 30 to October 1: concentrated perpetual-contract launches
3. October 19: Upbit and Bithumb listings in the Korean market

This follows a typical sequence of “concentrated initial liquidity → derivatives follow-up → regional market expansion.”

Spot Listing Timeline

All times below are UTC, organized by the effective times in the supplied exchange-event records. Multiple trading pairs on the same exchange with the same effective time are grouped together. The XT entry uses the official announcement time cited in the material; the discrepancy with the event record is retained below the table.

The XT event record in the supplied material gives 2026-09-30 10:00 UTC, but the official XT announcement it cites specifies CT/USDT trading opening at 2026-09-30 10:05 UTC and withdrawals opening at 2026-10-01 10:05 UTC. The table uses the announced trading time and does not treat the two records as the same precise point in time. Official XT announcement

Earliest spot records:

• Including Binance Alpha: Binance Alpha, September 30 at 08:00 UTC
• Considering only conventional exchange spot markets: Coinbase, Bitget, Gate, and OKX, around September 30 at 10:00 UTC
• XT’s official announcement time: September 30 at 10:05 UTC

Perpetual Listing Timeline

Perpetual launches were concentrated approximately 1–24 hours after the initial spot launch, showing that exchanges and derivatives markets began offering leverage, short exposure, and funding-rate trading very early. For price structure, this generally means that launch-phase volatility may be driven by spot buying and amplified by derivatives leverage and liquidations.

What This Timeline Means

First, initial liquidity was relatively concentrated.
$CT entered multiple spot markets on September 30, so early price discovery would be concentrated among several major exchanges. Differences in pair depth, regional user composition, and market-making arrangements may create short-lived price gaps.

Second, derivatives arrived very quickly.
Perpetuals on OKX, Aster, Bybit, Bitget, Gate, and Binance followed rapidly after the TGE. Early-listing analysis therefore needs to focus on funding rates, open interest, and liquidation volume alongside spot trading volume.

Third, the Korean market was a second-stage expansion.
Upbit and Bithumb listed on October 19, approximately 19 days after the initial launch. Upbit offered CT/BTC, CT/KRW, and CT/USDT, while Bithumb offered CT/KRW. This may increase local liquidity in the Korean market, but it may also bring regional premiums or discounts.

Data definitions.
The times above come from the supplied exchange-listing event records, using effective_at as the effective time. Multiple trading pairs on the same exchange with the same effective time are grouped together. The original Aster records contain duplicate or near-duplicate entries, so only one entry is retained at the exchange-and-product level. XT’s time instead follows the specific trading time in its official announcement. An exchange “listing record” does not establish that trading is available in every region as of the report date. Actual availability still depends on account location, product status, and exchange rules.

Conclusion

Concrete ($CT)’s main launch date was 2026-09-30: Binance Alpha came first, followed by spot trading on several major exchanges. Derivatives coverage expanded on 2026-10-01, followed by entry into Upbit and Bithumb on 2026-10-19.

Conclusion. To study $CT’s initial price performance, treat September 30, 08:00–10:00 UTC as the first price-discovery window, the October 1 perpetual listings as the leverage-volatility window, and the October 19 Korean exchange listings as a second regional-liquidity event.

Source and editorial note: This article was added to Thoughts based on the timeline supplied by the user, preserving the scope of the material as of 2026-10-23 UTC. No Surf, external translation service, or independent online verification was used in this task, and exchange-event data was not queried again. The TGE, listing records, announcement details, and Aster deduplication explanation are organized from the supplied material. The XT table entry was changed to 10:05 UTC according to the announcement cited in the material; the original event record’s 10:00 UTC is retained separately in the body. Binance Alpha is distinct from spot trading on Binance’s main exchange, and a Binance perpetual record does not prove a main-exchange spot listing. CT/U is preserved exactly as supplied, without assuming which asset U represents. The timeline identifies observation windows and does not prove that a listing event caused any particular price change. No monitoring was established and no trades were executed in this task.
