US spot Bitcoin ETFs acquire 18,991 BTC in five days, outpacing new supply

US spot Bitcoin ETFs have bought 18,991 BTC over five days, far outpacing new supply minted during that period. The Bitcoin all-time high by June 30 market sits at 2.7% YES, down slightly from earlier levels, while Bitcoin dipping to $60,000 in April looks increasingly unlikely.

Market reaction

The September and December all-time high markets are at 10.5% and 18.0% YES, respectively. The largest move in the last 24 hours was a 2-point spike in the September market. The ETF inflows have not yet shifted sentiment toward near-term all-time highs; traders remain cautious. Geopolitical context matters here too: President Trump’s comments on a near-complete deal to end the US-Israel-Iran conflict have pushed markets toward risk-on positioning, which benefits Bitcoin.

Why it matters

Total volume across these markets is $917 in USDC, which is thin. The cost to move prices by 5 percentage points varies: the September market requires $5,933, making it more resistant to large swings, while the June market needs only $959 for a similar move and is far more susceptible to volatility. Institutional buying at this pace (18,991 BTC in five days) can stabilize prices during geopolitical uncertainty, but the low liquidity in these prediction markets means the odds may not yet reflect the full impact of these inflows.

What to watch

At current odds, a YES share for an all-time high by June is priced at 2.7¢, offering a 37x return if it resolves. The two things that would support this bet: continued ETF inflows at or above the current pace, and further US-Iran diplomatic progress. Watch for announcements from asset managers like BlackRock or Fidelity regarding new Bitcoin allocations, which could move these markets quickly given the thin liquidity.
