Crypto enters September split on whether August's rally has legs

Bitcoin rallied roughly 24% in August, one of its strongest months of the year, and carries that momentum into a September packed with scheduled catalysts, BeInCrypto reported: a wave of token unlocks in the first week, a Federal Reserve rate decision, and a Senate vote that could reshape how the US regulates crypto altogether.

• Sept 1 — Sui (SUI): 13.53M tokens, about $9.73M, 0.33% of released supply
• Sept 2 — Ethena (ENA): 40.63M tokens, about $6.05M, all to the Ethena Foundation
• Sept 6 — Hyperliquid (HYPE): 9.92M tokens, about $797M by Tokenomist's estimate, 2.37% of released supply
• Sept 15 — Senate's first procedural vote on the Clarity Act market-structure bill
• Sept 16 — Federal Reserve rate decision, 2:00 pm ET

The Hyperliquid unlock deserves the closest attention. At about $797 million, it dwarfs the Sui and Ethena releases combined and equals 2.37% of HYPE's released supply hitting the market in a single day, per Tokenomist data cited by BeInCrypto. Ethena's allocation goes in full to its own Foundation rather than early investors, which tends to matter less for immediate sell pressure than unlocks that land in outside wallets instead of a foundation treasury.

The ETF side flipped first. US spot Bitcoin ETFs logged a $201.8 million net outflow on August 28, ending a nine-day inflow streak that had followed Bitcoin's largest weekly dollar gain on record. Weekly inflows across the group had cooled by more than half in the days before that. Bitcoin reserves held on Binance climbed to roughly 687,000 BTC, the highest level of 2026 according to CryptoQuant. That's roughly 70,000 BTC above the level seen in late April.

GSR's Andy Baehr, a 25-year Wall Street derivatives veteran, reads the same setup differently. He spent the summer counseling patience through what he called a "super slow summer" of thin volumes, after digital asset funds bled a record $8 billion across eight straight weeks of outflows. Then spot ETFs added nearly $2 billion in net inflows over five days, options activity picked back up, and funding rates on perpetual futures reinflated.

All of those are good market structure signs that this kind of rally is for real, and we can expect more energy to follow.

Baehr also wants the Clarity Act passed this year — the same bill facing a procedural Senate vote on September 15, with the ethics and stablecoin-yield provisions that could sink it still unresolved.

The Fed decision carries weight too. Baehr frames continued dollar-debasement trades favoring bitcoin and gold, tied to US federal debt crossing $40 trillion, as the reason this setup differs from past rallies that failed to hold.

Analyst Crypto Rover takes the opposite view, pointing to spot cumulative volume delta — a measure of whether real buying or leveraged futures positioning is driving a price move — that stayed flat through the weekend rally.

History offers mixed comfort. Bitcoin has averaged a 3.08% loss in September since 2013, according to Coinglass, the weakest month of the year on average. The last three Septembers reversed that pattern, closing up 5.16% in 2025 and 7.29% in 2024.

Traders get their answer on demand versus leverage only after the Fed decides on September 16, the Senate votes the day before, and the Hyperliquid unlock actually lands.
