ONDO and Jupiter Rally Shows Altcoin Appetite Is Back — But Not Altseason

What the rally actually signals

In ONDO, the demand signal was visible in both price and turnover. Yellow.com reported that Ondo Finance’s ONDO token gained roughly 13% in the 24 hours to May 4, 2026, trading near $0.313 with about $137.7 million in volume and a market cap near $1.52 billion . Phemex’s market snapshot the same day listed ONDO among leading altcoin gainers at +11.70%, while Bitcoin was up 0.49% and Ethereum 0.82% over the previous 12 hours . BanklessTimes separately reported that ONDO had broken above an eight-month descending trendline with $120.7 million in 24-hour turnover .

Those snapshots are not identical, but they point in the same direction: traders were willing to bid a token tied to the real-world-asset theme .

Jupiter adds the DeFi side of the story. Recent altcoin market coverage listed JUP alongside ONDO and other sudden movers . Longer-range 2026 analysis has framed Jupiter as part of Solana’s high-speed DeFi infrastructure, while placing Ondo among projects tied to tokenized assets and synthetic cash flows .

Taken together, the signal is not that every altcoin is healthy. It is that capital is again chasing recognizable themes: RWA, DeFi infrastructure, and tokens with fresh momentum .

Why it still is not altseason

Altseason is a breadth claim, not a price-pop label. CoinMarketCap’s method defines Altcoin Season as a period when 75% of the top 100 coins, excluding stablecoins and some asset-backed tokens, outperform Bitcoin over the past 90 days . BlockchainCenter uses a similar 75% hurdle for the top 50 coins and showed an Altcoin Season Index of 35 with the status ‘It is not Altcoin Season’ on May 9, 2026 .

MEXC market commentary likewise said an index reading of 35 remained firmly in Bitcoin Season territory, even while long-term charts hinted at a possible future rotation . That gap between single-token momentum and market-wide breadth is the whole point: ONDO and JUP can rally while most major altcoins still fail to beat Bitcoin on the index’s 90-day test .

The market looks selective, not indiscriminate

Crypto.com’s May 2026 outlook described the Altcoin Season Index as still in the low thirties, corroborating a Bitcoin-led phase, while noting rotation toward assets with concrete milestones . Phemex’s snapshot similarly described sector rotation and selective risk appetite rather than a broad sweep across altcoins .

Some analysts expect this selectivity to persist. ForkLog reported that CoinEx Research chief analyst Jeff Ko predicted the absence of a traditional altcoin season in 2026 and said liquidity may be ‘ruthlessly selective’ rather than lifting the entire long tail . AInvest analysis also argued that 2026 altcoin growth could be structured around RWA tokenization and DeFi infrastructure, not blanket speculation .

What would confirm a real shift

Three signals would matter most before calling this a true altcoin season:

• Breadth above the threshold. The Altcoin Season Index would need to approach or exceed 75 under CoinMarketCap or BlockchainCenter-style definitions .
• Sustained outperformance versus Bitcoin. More large altcoins would need to beat Bitcoin over the same 90-day window, not merely rise in U.S. dollar terms while BTC remains the stronger relative trade .
• Rotation beyond a few leaders. Leadership would need to broaden beyond one-day movers and a handful of RWA or DeFi names; current commentary still describes rotation toward specific milestones and sector catalysts .

Bottom line

ONDO and Jupiter are credible evidence that altcoin risk appetite is improving . They are not credible evidence, yet, that altseason has arrived. The stronger headline is selective rotation: traders are rewarding RWA and DeFi narratives, while broad market indicators still show Bitcoin leading or altcoins trailing relative to the 75% benchmark .
