Altcoin Season 2026 Starting? These Are Potential Altcoins You Must Monitor

The crypto market entered a busier phase in September 2026. Altcoin season, potential altcoins, and crypto bullishness have again become widely discussed topics after a number of alternative assets began recording gains and market indices showed recovery.

BlockchainCenter data as of September 23, 2026 shows the Altcoin Season Index at 53, still in the transition zone and not yet reaching the 75 mark used as the altcoin season threshold. 

CoinMarketCap also uses a similar approach, measuring how many of the top 100 crypto assets are able to outperform Bitcoin over 90 days.

This means the market is starting to give more room to altcoins, but not all assets are moving in the same direction. Conditions like this make asset selection and volume monitoring more important than simply chasing tokens that are currently rising.

Key Takeaways

• The Altcoin Season Index has not reached level 75, so there is no confirmation of a full altseason.
• GIGA, RAY, SOL, TURBO, and XG are included in the list of altcoins discussed by CoinMarketCap Community.
• Altcoin performance still depends on liquidity, Bitcoin, trading volume, and market sentiment.

List of Potential Altcoins in 2026 Worth Monitoring

A CoinMarketCap Community article published by Crypto News Land on September 23, 2026 discussed five assets considered worth watching ahead of a potential increase in retail investor participation. Those five assets are GIGA, RAY, SOL, TURBO, and XG.

It should be noted that CoinMarketCap Community is a community content channel. CoinMarketCap explicitly states that the material comes from community contributors and asks readers to do their own research or DYOR. 

Therefore, the term “potential” in this article refers to assets that are interesting to monitor, not an investment recommendation or a guarantee that prices will rise.

1. GIGA

Gigachad (GIGA) is a memecoin running on the Solana network. This token is in the high-risk asset segment that is highly dependent on liquidity, community activity, and market sentiment.

CoinMarketCap data shows GIGA has around 9.3 billion tokens in circulation out of a maximum of 10 billion. The price and volume of this token can change quickly because its market capitalization is much smaller than major assets such as SOL.

These characteristics make GIGA relevant to monitor when retail investor interest in memecoins rises again. However, its volatility also means price reversals can happen quickly.

2. Raydium (RAY)

Raydium (RAY) has a different character because this token is directly tied to DeFi and trading activity in the Solana ecosystem.

CoinMarketCap recorded RAY at around IDR 33,018 with a market capitalization of around IDR 8.9 trillion and 24-hour trading volume of around IDR 1.26 trillion in data updated on September 23, 2026. Raydium's TVL was also recorded at around IDR 23.81 trillion.

RAY's movement in recent weeks has also been quite strong. CoinMarketCap AI analysis on September 22 noted that RAY had risen around 39.92% in seven days and 131.89% in 30 days, before experiencing a mild correction due to profit-taking.

This performance makes RAY interesting to observe if trading and DeFi activity on Solana continues to increase.

3. Solana (SOL)

Solana (SOL) is an asset with a much larger market capitalization than GIGA and TURBO. Because of that, SOL's movement is also often an important indicator for seeing the broader strength of the Solana ecosystem.

CoinMarketCap data on September 23, 2026 shows SOL at around US$119, after rising around 26.92% in 30 days. During the same period, SOL also recorded several sessions of gains as the crypto market generally began to recover.

SOL's position is important because several assets in this list, including RAY and GIGA, have ties to the Solana ecosystem.

If capital inflows into that network increase, tokens that have trading activity and network usage can also receive greater attention. Still, ecosystem correlation does not mean every Solana token automatically follows SOL's movement.

TURBO and XG Are Two Altcoins to Watch

4. Turbo (TURBO)

Turbo (TURBO) is an Ethereum-based memecoin with a highly speculative character. This token is known for its creation history involving GPT-4 in a memecoin creation experiment in 2023.

On September 23, 2026, CoinMarketCap data showed TURBO's price at around IDR 19.80, with a market capitalization of around IDR 1.36 trillion and 24-hour trading volume of around IDR 283.66 billion. Almost the entire maximum supply of 69 billion TURBO has been circulating.

TURBO's price has also shown gains in recent sessions. CoinMarketCap historical data recorded a price of around US$0.001123 on September 23, up around 5.61% in 24 hours based on that converter's data.

However, there is a factor to note. CoinMarketCap AI noted that Bitget delisted the TURBO/USDT trading pair in September 2026. Reduced trading access on certain exchanges can affect liquidity, although TURBO remains available on other platforms.

5. XG

XG is also listed among the assets in the CoinMarketCap Community article. The CoinMarketCap page for XG currently displays the asset with the name GIGA and ticker XG, so the token's identity needs to be noted so it is not confused with Gigachad (GIGA), which has a different ticker.

CoinMarketCap data shows XG has a total supply of around 472.15 million tokens, a maximum of 1 billion, and a circulating supply of around 135.43 million tokens. 

The page is still in preview page status, so fundamental and market information for this asset is relatively limited compared with tokens that already have more complete market pages.

These conditions mean XG needs to be treated more carefully. Liquidity, the exchanges where the token is traded, project activity, and official information developments are factors that need to be checked before drawing conclusions about its prospects.

Has Altcoin Season 2026 Started?

The answer has not been confirmed.

The Altcoin Season Index from BlockchainCenter was at 53 on September 23, 2026. That figure is still between the Bitcoin Season and Altcoin Season zones. BlockchainCenter sets 75 as the threshold when at least 75% of the assets in the group they measure outperform Bitcoin over 90 days.

CoinMarketCap uses a different method but a similar principle. CMC compares the performance of the top 100 crypto assets against Bitcoin over 90 days and calls the condition Altcoin Season when at least 75% of those assets outperform Bitcoin.

Therefore, gains in several altcoins are not enough to say the market has entered altseason.

There are several other indicators that can be observed:

• Bitcoin dominance: a decline in Bitcoin dominance can indicate capital is starting to move into altcoins.
• ETH/BTC: Ethereum strengthening against Bitcoin is often used to gauge changes in market leadership.
• Altcoin volume: price increases accompanied by larger volume give a different picture than increases with thin liquidity.
• Stablecoin liquidity: an increase in stablecoin liquidity can provide fuel for trading activity.
• Market breadth: the more altcoins outperform Bitcoin, the stronger the indication of capital rotation.

In other words, looking for which altcoins have the potential to rise should not rely only on one token's chart. Broader market conditions remain the main factor.

What Are the Risks of Buying Altcoins When the Market Turns Bullish?

The early phase of an altcoin rally often tempts investors to chase assets that have already moved the fastest. The problem is that prices that rise quickly can also fall at the same speed. Humans do have a remarkable talent for treating a green chart as a personal invitation.

GIGA and TURBO, for example, are in the memecoin category that is heavily influenced by sentiment and trading activity. Meanwhile, RAY is more closely tied to Solana DeFi activity, and SOL has broader network fundamentals. XG has more limited market information, so its risks need special attention.

Investors also need to pay attention to market cap, volume, liquidity, token supply, token unlocks, network activity, and project developments. Price increases without adequate volume or liquidity support can make prices more prone to correction.

Therefore, the list of potential altcoins in 2026 such as GIGA, RAY, SOL, TURBO, and XG is better used as a watchlist, not a list of tokens that are guaranteed to be profitable.

Altcoin Season is a period when most altcoins outperform Bitcoin over a certain measurement period. CoinMarketCap uses a threshold of 75% of the top 100 crypto assets outperforming Bitcoin over 90 days.

Has Altcoin Season 2026 started?

It has not been broadly confirmed because the Altcoin Season Index is still below the 75 threshold. BlockchainCenter recorded an index of 53 on September 23, 2026.

Which potential altcoins in 2026 are discussed?

A CoinMarketCap Community article from Crypto News Land lists GIGA, RAY, SOL, TURBO, and XG as the five assets discussed. The article is community content, so the list should be treated as research material, not an investment recommendation.

Are GIGA and XG the same token?

They cannot simply be equated. The CoinMarketCap page for XG displays the name GIGA with the ticker XG, while Gigachad uses the ticker GIGA, so the contract and project identity need to be checked before transacting.

Why is RAY interesting to monitor during altseason?

RAY is closely tied to Raydium's activity, one of the trading and DeFi protocols in the Solana ecosystem. An increase in Solana activity and liquidity can be one of the factors influencing demand for RAY.

Is TURBO a memecoin?

Yes. TURBO is an Ethereum-based memecoin with a maximum supply of 69 billion tokens, and almost all of that supply is already in circulation.
