Cardano (ADA)
For Cardano (ADA) and all other altcoins I will discuss today, ETF approvals are imminent in October. Cardano’s approval date is set for 26th October. By that date, the SEC must decide on the Grayscale ADA ETF filing. It has already extended this review various times. The SEC will either approve or reject Grayscale ADA ETF filing. So, this time around, it’s all or nothing.
According to Polymarket, currently there’s a 90% approval expectation. Polymarket is a prediction and betting platform. So, such SEC approval is a critical milestone for Cardano. It can trigger major price movement and institutional inflows.
The SEC also made some changes in the review process. It reduced the maximum time between filing and launching an ETF. Previously, this was 240 days. Now it’s a mere 75 days. So, it’s good to see the changing ETF landscape in the US. The period leading up to 26th October, may see quite a bit of volatility. On the other hand, there’s also high market anticipation.
Next month is definitely one to watch for Cardano 🔥
The SEC must decide on Grayscale’s standalone Cardano $ADA ETF application by October 26 🇺🇸

With a current ADA price of 79 cents, this looks like a good entrance. The ADA market cap is $28.9 billion. ADA’s ATH is still $3.09, from September 2021.
Ripple (XRP)
Ripple (XRP) has a few more spot ETF filings pending. There are 6 pending XRP spot ETF filings that I expect the SEC to decide on in October 2025. The final approval dates are tightly packed together in a timeline as follows:
- •18th October: Grayscale XRP ETF decision
- •19th October: 21Shares XRP ETF decision
- •20th October: Bitwise XRP ETF decision
- •23rd October: CoinShares and Canary Capital XRP ETF decisions
- •24th October: WisdomTree XRP ETF decision
🚨 XRP ETF FILINGS with the SEC 🚨
1️⃣ Bitwise – $5B
2️⃣ Canary Capital – $200M
3️⃣ 21Shares – $7B
4️⃣ WisdomTree – $113B
5️⃣ ProShares – $70B (XRP, Short, Ultra, UltraShort)
6️⃣ Grayscale – $40B
7️⃣ CoinShares – $5B
8️⃣ Volatility Shares – $5B (XRP, 2x, -1x)
9️⃣ Franklin Templeton – … pic.twitter.com/KPXOS4WOXY— John Squire (August 30, 2025)
There’s also a Franklin Templeton XRP ETF filing. However, the SEC is not expected to rule on this until 14th November. So, as you can see, busy ETF times ahead for Ripple. If we look at Polymarket, the expectation is as high as 97%.

These filings were made under the 240‑day ruling. So, there’s no guarantee that the SEC will approve them. There’s, of course, always the possibility that the SEC won’t approve these filings. However, in that case, expect renewed filings under the new 75‑day fast‑track ruling. This will push a launch back to Q1 2026. On the other hand, approval will see the XRP price flying.
I’ve been doing more research and even though #XRP#ETFs fall under the old 240‑day process with October deadlines, I think the SEC is unlikely to approve. XRP futures only reach the 6‑month mark Oct 21, so filings will likely be rejected and re‑filed under the new 75‑day… pic.twitter.com/zp5XfZ1Twf

The current XRP price is $2.85 with a $170 billion market cap. XRP under $3 looks like a good entry point.
Solana (SOL)
Solana (SOL) is the next of today’s altcoins in line for an SEC ETF approval in October. Between 10th and 16th October 5 SOL ETF filings are due for SEC review.
🚨 Solana Momentum is Building Fast

— CryptoKing (September 20, 2025)
There are some heavy hitters involved in these filings. For instance, Grayscale, VanEck, 21Shares, Canary, and Bitwise. Like Ripple, they were still filed under the 240‑day rule.
In early September, Polymarket saw an 82% approval chance for this year. An approval would make Solana the third major Layer‑1 network to gain regulated ETF access in the United States. That’s, of course, after Bitcoin and Ethereum. Such an approval would most likely be attracting billions in institutional inflows. Not to mention that it would spark a price surge.
Xrp ETF 2025 approval odds at 87% on polymarket…
Personally think closer to 100%.

The recent SEC rule changes, make for a different regulatory landscape. Especially if we take the Genius Stablecoin Act onboard as well. These should have a positive impact on Solana’s ecosystem development. For example, its DeFi use cases.
🚨 SEC just approved new listing rules.
Spot crypto ETFs (like XRP, SOL) can now be launched in just 75 days — down from 240.
October could trigger the next ETF wave. Buckle up. 🚀#XRP#ETF#Crypto#Ripple#SOL#SECpic.twitter.com/xvpIc62SGa

Recently, the SOL price went up to $250. However, under the current market conditions, all altcoins suffer. The current SOL price is $209 with a $113 billion market cap. Be aware that SOL has an infinite supply. Still, in a bull run, SOL could go anywhere between $800 and $1,000.
Chainlink (LINK)
Chainlink (LINK) currently has two major LINK ETF filings with the SEC.
- Grayscale filed an S‑1 registration for a spot

However, there have been no exact final decision dates publicly announced yet. So, both filings are waiting for these dates to be announced. Nonetheless, a date in Q4 2025 is expected.
Chainlink is working hard to strengthen its institutional credibility. It recently announced two major partnerships:
- The Intercontinental Exchange (ICE). This brings high‑quality derived forex and precious metals’ data on‑chain.

These partnerships reinforce Chainlink’s role as a decentralized oracle provider. It bridges TradFi with Web3.
So, looking at the LINK price, I always wonder why it’s not at least $100. However, the current LINK price is $21.28 with a $14 billion market cap. A price around $20 is a good entry for LINK, in my book.
Stellar (XLM)
With Stellar (XLM) we’re looking at two spot ETF filings.
- The Hashdex Nasdaq Crypto Index US ETF. This is the primary ETF holding Stellar (
XLM) approved by the SEC as of 24th September 2025. It operates under the new streamlined listing rules with a 75‑day window of approval. The ETF also includesXRPandSOL.🔥 As of Sep 25, the Hashdex Nasdaq Crypto Index US ETF can now hold assets other than $BTC and $ETH, this would mark one of the first ETFs to hold Stellar $XLM, which makes up 0.34% of the fund alongside $XRP & $SOL.

— Matze XRP 2023👻 (September 24, 2025)
Both filings have an expected review and potential approval timeline in late 2025, possibly stretching into early 2026.
But first, let’s get back to the Hashdex Nasdaq Crypto Index US ETF. As you could see, this is a U.S.-regulated ETF portfolio. This makes Stellar more accessible to institutional and retail investors. It has the potential to boost liquidity and price due to increased demand through regulated channels.
Here we go…

The current XLM price is 36 cents with an $11.6 billion market cap. It’s slightly down on the day, but up by 275 % over 1 year.
