Altcoins Hyperliquid, Pump.fun Post Double-Digit Weekly Gains as Bitcoin Nears $90K

In brief

• Bitcoin’s range-bound price action is triggering a classic capital rotation into high-beta altcoins.
• A falling U.S. Dollar Index is reinforcing expectations for looser financial conditions and asset inflation.
• Analysts say only altcoins with strong fundamentals and narrative momentum will sustain gains in a crowded market.

Altcoins including Hyperliquid, River, and Pump.fun have seen a sustained rally over the past week, notching double-digit gains over the period. Hyperliquid is the clear winner among the top 100 coins by market cap, surging 65% over the past week, according to CoinGecko data. Pump.fun, Canton and River and followed closely with 33.6%, 23.3% and 21.8% gains respectively. The surge in altcoins comes as Bitcoin consolidates between $95,000 and $81,000, which has seen the top crypto’s dominance form a local top around 59.94 to 59.50. Bitcoin is currently trading at $89,373, up 1.9% on the day, per CoinGecko data.

Meanwhile, the past week has seen altcoin dominance explode from roughly 6.7% to 7.06%. “Traders are looking for quick wins in projects that have solid fundamentals,” Rachel Lin, CEO and Co-founder of SynFutures, told Decrypt. As a result, users on prediction market Myriad, owned by Decrypt’s parent company Dastan, flipped bullish on Pump.fun’s outlook Wednesday after a week of bearish sentiment. Myriad traders now place a 56% chance on PUMP’s next move taking it to $0.005 rather than $0.001. Interestingly, a market on Hyperliquid’s outlook that resolved when it hit $30 Tuesday also showed a late flip to bullish sentiment after a week in which bears dominated. Myriad users expect Hyperliquid’s airdrop will occur before Pump.fun’s, assigning a 54% chance to this outcome.

The trend signals where speculative capital is moving during a period of macro uncertainty, revealing a shift in risk appetite beneath the market’s surface.  Supportive macro backdrop The U.S. Dollar Index (DXY), which measures the dollar against a basket of major currencies, has trended lower from nearly 110 in January 2025 to 95.70 this week. This dollar softness reinforces expectations of looser financial conditions. “The value of the dollar is great," U.S. President Donald Trump told Fox News Tuesday.

Most people don’t realize what Trump just said:

For 12+ months, the US Dollar has been in a sharp decline, falling -10% in 2025 in its worst year since 2017.

Minutes ago, for the first time, President Trump commented on the decline in the USD:

“The U.S. dollar’s relative oversupply compared to other assets is manifesting in depreciation and sector rotations,” Lacie Zhang, Market Analyst at Bitget Wallet, told Decrypt. “This potential asset inflation underscores the need for diversified portfolios to capitalize on these inflows.” Zhang noted that each altcoin’s surge is driven by a distinct catalyst. “River benefits from capital inflows and high short-term trading volumes, while Hyperliquid gains from strong silver trading activity, boosting project revenues,” the analyst said. Pump.fun’s role as meme coin infrastructure, meanwhile, “signals renewed interest in the meme sector, encouraging projects to focus on real utility and community-driven momentum.”

Such selectivity suggests a maturing market, SynFutures’ Lin said, noting that, “A few winners are emerging, but there are so many more tokens than before that liquidity for tokens that don’t capture mindshare won’t accrue value.” Analysts see a phased recovery forming for the altcoin sector in the coming months. “Following Q4 2025’s corrections, the altcoin market is in a bottoming phase in Q1 2026, with opportunities for phased rebounds driven by improving sentiment and liquidity,” Zhang said. She emphasized that projects prioritizing fundamentals such as adoption and innovation will build the long-term resilience needed to navigate short-term volatility. For now, the rally in select altcoins stands as a testament to capital seeking opportunity, even as the crypto market waits for Bitcoin to decisively reclaim its bullish momentum.
