Key Insights: Cuts Without Conviction

For crypto, the data points to elevated open interest and steady funding. BTC OI rose to $83.1b from $82.8b at the start of the week (+0.4%), while ETH OI edged lower to $63.1b from $63.6b (-0.7%). Funding rates have been consistently positive, indicating a persistent willingness to pay for long exposure despite a rangebound spot price in both BTC and ETH and a bearish skew in options markets. This buildup leaves positioning sensitive to a macro surprise, where a sharp move in spot could quickly trigger liquidations or, conversely, fuel a breakout.

Outside of BTC and ETH, altcoins snapped their two-week winning streak, falling -5.17%. Breadth flipped negative at -72 (14 advancers, 86 decliners), a sharp reversal from last week’s broad rally (+80 breadth, +7.4% cap). The pullback highlights fading risk appetite, with participation narrowing and sector-specific catalysts struggling to offset broader weakness.

Within that backdrop, sector performance was largely uniform. Gains were led by Exchange tokens (+7.1%), Staking Services (+3.8%), and Perp Dexs (+1.6%), with ASTER and AVNT standing out after their recent airdrops revived the airdrop meta and spurred users to resume farming points in perp DEX protocols. Outside of a handful of winners, most sectors bled this week, with Social (-4.5%), DeFi (-9.4%), DePIN (-10.0%), Memecoins (-10.2%), and RWAs (-11.1%) all posting steep losses. The breadth of weakness across speculative segments points to fading risk appetite, as capital retreats from higher-beta trades and narrows toward defensive or narrative-driven pockets.

Our Take: Historically, periods of strong altcoin breadth and performance are often followed by a moderation phase, suggesting that participation could taper off in the weeks ahead unless a clear macro catalyst revives risk appetite. With the altcoin index now in altcoin season territory, we expect short-term momentum to cool, with gains likely to become even more selective and concentrated in sectors and protocols with clear catalysts.

Onchain rates were mixed this week, with stablecoin yields climbing while ETH rates weakened. USDC APY rose 9.7% WoW and USDT gained 15.9% WoW. The moves came as supply contracted significantly, with USDC on Aave losing 25% of its capacity. WETH yields slipped 13.8% WoW as Aave supply jumped nearly 14%, pointing to ETH accumulation by users chasing yield, and softer borrow appetite. The divergence reinforces how traders are selectively extending risk into stablecoin lending while shying away from ETH leverage.

Chain netflows showed sharp divergence across ecosystems, with Base seeing $271m outflows, continuing its struggle with user retention, thin liquidity, and reputational setbacks. Ethereum also recorded $87m outflows, tied to a 2.6m ETH exit queue. Meanwhile, BNB Chain posted $91m inflows, riding record activity, token burns, and post-CZ sentiment as it broke to new all-time highs.

RWAs extended gains, with aggregate AUM up 2.3% WoW. Ondo led with an 8.5% gain, pushing TVL to ~$1.66b as tokenised Treasuries trading drew strong demand post-Fed cuts. Maple rose 2.4%, surpassing $4b AUM on the back of syrupUSDC scaling across Solana and Arbitrum. Paxos gained 2.5%, with PAXG inflows tied to gold’s strength and stablecoin integrations. Ondo and Maple continue to anchor growth, positioning RWAs as one of the most structurally consistent themes in DeFi.

Our Take: Stablecoin yields and Arbitrum inflows highlight a sustained risk-on tilt, with traders selectively seeking looping yield via stables and chasing ecosystem narratives. RWAs remain the standout growth engine, and if Ondo and Maple sustain current momentum, tokenisation could become the primary driver of DeFi AUM growth heading into Q4.

Chainlink has surged to an oracle market dominance level not seen since April 2021 this week, with market share of oracle total value secured hitting 69.4%. The market share growth, which has been in a general upward trend since November 2023, coincides with Polymarket’s decision on September 12th to adopt Chainlink for resolving price-based bets. This is a major validation for the oracle, given Polymarket’s rise as what’s been dubbed ‘the wisdom of the crowds in financial form’, in an industry that bridges crypto-native infrastructure with non-native capital, that is regularly achieving $1b in trading volume per month. Beyond Polymarket, Chainlink’s multi-chain footprint, spanning Ethereum, Arbitrum, Base, and Solana, has reinforced its status as the default oracle layer across DeFi.

This resurgence matters because oracles are the invisible backbone of onchain finance. Over the past two years, Chainlink’s market share had eroded as rivals like Pyth and Redstone gained traction with faster, cheaper price feeds. The return to near 70% dominance highlights how institutional-facing, reliability-first demand is reasserting itself, particularly from platforms where trust in final settlement is critical.

Our Take: Chainlink’s momentum is likely to sustain. With Polymarket setting a precedent, other prediction and derivatives platforms could follow suit, especially those scaling into regulated environments. If this adoption wave sustains, Chainlink could push back above 70% dominance in late 2025, cementing itself once again as the oracle layer of choice for high-value DeFi and prediction markets.
